Chevy Safety Assist (Silverado, Equinox, Tahoe, Suburban, Traverse), GMC Pro Safety (Sierra, Yukon, Acadia), Cadillac ADAS (Escalade, CT5, Lyriq), and Buick Driver Confidence (Enclave, Encore GX) all depend on a single forward-facing camera mounted at the top of the windshield — and a long-range millimeter-wave radar hidden behind the Chevy bowtie, GMC red emblem, Cadillac crest, or Buick tri-shield (or in a lower-bumper sensor pod on certain Silverado HD, Yukon, Escalade, Lyriq trims). Short-range corner radars sit in the rear bumper corners on most 2022+ trims. Super Cruise-equipped Cadillac (Escalade, CT5, Lyriq) and select Chevy (Bolt EUV, Silverado) trims require an extended dynamic step plus a DLC-learned GRBL handshake on top. Removing that windshield breaks the camera geometry. Legendary Auto Glass performs GM forward-camera static and dynamic calibration in-house via GDS2 / MVI / GM SPS / GMDI, plus long-range radar re-aim behind the brand emblem where equipped, plus extended dynamic + GRBL handshake on Super Cruise trims, plus corner-radar aim on 2022+ trims — same appointment as your windshield replacement, OEM-spec glass, documented pre- and post-scan report.

Chevy Safety Assist, GMC Pro Safety, Cadillac ADAS, and Buick Driver Confidence are sibling driver-assistance suites built around a single-lens forward-facing camera mounted at the top center of the windshield, just below the rearview mirror. The camera reads lane geometry, traffic signs, vehicles ahead, and pedestrians. A separate long-range millimeter-wave radar sensor is mounted at the front of the vehicle on most trims — most commonly hidden behind the front brand emblem (Chevy bowtie, GMC red, Cadillac crest, Buick tri-shield), or on certain trims located in a lower-bumper sensor pod (Silverado HD, Yukon, Escalade, Lyriq). On most 2022+ trims, additional short-range corner radars sit in the rear bumper corners. The camera, the long-range radar, and the short-range corner radars are paired inputs that feed Automatic Emergency Braking, Forward Collision Alert, Front Pedestrian Braking, Lane Keep Assist with Lane Departure Warning, Following Distance Indicator, IntelliBeam, Adaptive Cruise Control, Rear Cross Traffic Alert, Lane Change Alert with Side Blind Zone Alert, Reverse Automatic Braking, HD Surround Vision, and (on Cadillac trims and select Chevy trims) Super Cruise hands-free highway driving. Super Cruise adds a high-definition map database plus a lidar-mapped geo-restriction layer, and requires a separate DLC-learned GRBL (geo-referenced) handshake. That entire geometry stack is calibrated to within a fraction of a degree at the factory. When we remove your windshield, the camera calibration is broken. The radar calibration can also be disturbed by any front-end work that touches the grille or bumper area.
Single-lens forward-facing camera mounted in a bracket at the top-center of the windshield, just below the rearview mirror — the same physical location across Silverado, Equinox, Tahoe, Suburban, Traverse (Chevy); Sierra, Yukon, Acadia (GMC); Escalade, CT5, Lyriq (Cadillac); Enclave, Encore GX (Buick). The long-range millimeter-wave radar is hidden behind the front brand emblem — Chevy bowtie, GMC red, Cadillac crest, Buick tri-shield — on most trims, or sits in a lower-bumper sensor pod on certain Silverado HD, Yukon, Escalade, Lyriq trims. Short-range corner radars are mounted in the rear bumper corners on most 2022+ trims. Super Cruise-equipped trims additionally carry an HD-map database and require a DLC handshake to confirm geo-restriction map coverage before hands-free driving will engage.
Any windshield removal and replacement, windshield bracket adjustment, suspension work, front-end collision repair, wheel-alignment change, or anything that disturbs the front emblem or bumper fascia invalidates the factory camera and radar calibration. GM does not separately mark which leg was tripped; the GM published procedure is to recalibrate both whenever the camera is disturbed, and to re-aim the long-range radar whenever the front radar has been disturbed. Short-range corner-radar aim is a separate required step on every 2022+ trim where corner radar is equipped. Super Cruise trims additionally require the extended dynamic calibration step and a DLC-learned GRBL handshake to confirm HD-map geo-restriction is active. Buick Driver Confidence Plus trims step the procedure up further — the additional short-range corner radars require their own aim stage as a separate required step.
GM does not always illuminate a dashboard warning when calibration is incorrect — particularly for partial miscalibrations where the camera or radar is only slightly off-axis. Automatic Emergency Braking will brake at the wrong distance — usually too late, sometimes for the wrong target. Forward Collision Alert will trigger at the wrong range. Front Pedestrian Braking will react to phantom or missed targets. Lane Keep Assist with Lane Departure Warning will steer toward an off-center lane position or fail to engage. Adaptive Cruise Control will pace the wrong lead vehicle, including cars in adjacent lanes during a lane change. Rear Cross Traffic Alert can report false negatives on real vehicles. On Super Cruise trims the geometry is even more critical — the forward camera reads lane geometry AND the system runs a GRBL handshake against the HD-map database to confirm geo-restriction coverage. A miscalibrated camera will silently produce a wrong GRBL handshake, and Super Cruise hands-free driving may disengage unexpectedly, fail to engage at all, or engage in stretches where it should not. Most drivers will not feel anything is wrong until the system fails to react in an actual emergency. AGSC-certified tooling and the per-OEM published procedure matter — the long-range radar re-aim behind the Chevy bowtie, GMC red, Cadillac crest, or Buick tri-shield is the leg most often skipped at non-OEM shops.
When we remove your GM windshield, the forward camera comes with it (or is detached from the glass and must be reattached to the new windshield). Either way, the precise factory geometry GM established at the assembly plant is now broken. The camera is aligned to a fraction-of-a-degree tolerance — a 0.5° error at the camera translates to a lane-line position error of several feet at 100 yards ahead. Static and dynamic calibration — plus long-range radar re-aim behind the Chevy bowtie, GMC red emblem, Cadillac crest, or Buick tri-shield — re-teach the camera and the radar where straight-ahead is so AEB, Forward Collision Alert, Front Pedestrian Braking, Lane Keep Assist, Following Distance Indicator, IntelliBeam, Adaptive Cruise Control, Rear Cross Traffic Alert, Lane Change Alert with Side Blind Zone Alert, Reverse Automatic Braking, and HD Surround Vision react on the road the car actually sees — not a road that is several feet offset from reality. On Super Cruise-equipped Cadillac trims (and select Chevy trims) the geometry is even more critical: the forward camera reads lane geometry AND the system runs a GRBL handshake against an HD-map database to confirm geo-restriction coverage. A miscalibrated camera will silently produce a wrong GRBL handshake and Super Cruise hands-free driving may disengage unexpectedly or fail to engage. The long-range radar re-aim is a separate required step; skipping it leaves AEB and Adaptive Cruise Control operating with a mis-aimed radar even after the camera leg is corrected.
Every major ADAS suite uses a windshield-mounted camera — but the radar placement (behind the Chevy bowtie, GMC red emblem, Cadillac crest, or Buick tri-shield on GM, behind the Hyundai "H" or Kia "K" emblem on Hyundai/Kia, behind the grille on Toyota, behind the front "H" emblem on Honda, in a bumper pod on Ford), the procedure generation logic, and the trim-year matrix all differ. Specialized tooling and per-OEM procedures (GM GDS2 / MVI / GM SPS / GMDI) matter. Generic "ADAS calibration" without model-specific protocol is how the long-range radar re-aim behind the brand emblem gets skipped or done wrong.
Single-lens forward-facing windshield camera at top-center, just below the rearview mirror — shared mounting geometry across Silverado, Equinox, Tahoe, Suburban, Traverse (Chevy), Sierra, Yukon, Acadia (GMC), Escalade, CT5, Lyriq (Cadillac), and Enclave, Encore GX (Buick). A separate long-range millimeter-wave radar is hidden behind the Chevy bowtie, GMC red, Cadillac crest, or Buick tri-shield on most trims, or sits in a lower-bumper sensor pod on certain Silverado HD, Yukon, Escalade, Lyriq trims. Short-range corner radars sit in the rear bumper corners on most 2022+ trims. Super Cruise-equipped Cadillac (and select Chevy) trims add an HD-map database plus a lidar-mapped geo-restriction layer requiring a DLC-learned GRBL handshake.
Chevy Safety Assist baseline trims and Buick Driver Confidence baseline trims use static calibration only. Most Cadillac ADAS and GMC Pro Safety trims require static plus dynamic plus long-range radar re-aim behind the brand emblem. Super Cruise trims (Cadillac Escalade, CT5, Lyriq, select Chevy Bolt EUV and Silverado trims) require static plus dynamic plus long-range radar re-aim plus the extended dynamic step plus the DLC GRBL handshake. 2022+ trims with short-range corner radars require an additional corner-radar aim. AGSC-certified tooling and the per-OEM published GDS2 / MVI / GM SPS / GMDI procedure matter.
Single-lens forward-facing windshield camera in a bracket at the top-center, just below the rearview mirror. A separate millimeter-wave radar sits behind the grille; on some TSS 3.0 trims a second corner radar sits in the bumper. Driver-monitoring camera added inside the cabin on some 2022+ models.
Static and dynamic calibration required. The OEM published procedure covers the windshield-mounted camera, the grille-mounted radar, and (when equipped) the in-cabin driver-monitoring camera. Radar re-aim is a separate required step on every TSS 3.0 trim where radar is present. Lexus Safety System+ vehicles share the Toyota published procedure family. TSS 2.0 / 2.5 trims use static target only.
Single-lens forward-facing windshield camera in a bracket at the top-center, just below the rearview mirror. A separate millimeter-wave radar sits behind the front Honda "H" emblem on most 2018+ models, or in a lower-bumper sensor pod on certain trims (2022+ Civic, 2023+ CR-V, most Pilot and Passport models).
Camera plus radar calibration depending on year and trim. Earlier Honda Sensing trims use static target calibration only. Current Honda Sensing trims require both static and dynamic procedures plus bumper-radar re-aim whenever radar is equipped. AcuraWatch-equipped Acuras follow the same OEM published procedure family.
Stereo camera pod (two cameras in one bracket) at the top-center of the windshield, below the rearview mirror. No radar sensor — the cameras do all the work.
Static target calibration only. Subaru requires the vehicle be placed at a fixed distance from a printed target board, on level ground, with a specific tire pressure and fuel level. No driving required and no radar calibration involved.
Single-lens forward-facing windshield camera plus front-radar cluster (behind the Ford grille emblem or in a lower-bumper pod). Co-Pilot360+ BlueCruise trims add an extension to the dynamic calibration step for hands-free highway driving.
Static and dynamic calibration required. Radar re-aim required when front radar is equipped. BlueCruise trims require both static and dynamic steps.
Single-lens forward-facing windshield camera at the top-center, just below the rearview mirror. A millimeter-wave radar hidden behind the Hyundai "H" or Kia "K" emblem in the grille on most HDA-equipped trims from 2022 onward.
Static only on 2019-2021 SmartSense + Drive Wise trims without HDA. Static plus dynamic plus grille-radar re-aim on Hyundai HDA-equipped Palisade, Sonata, Tucson, Santa Fe, Elantra 2022+, Ioniq 5 and Kia HDA-equipped Telluride, Sorento, Sportage 2022+, K5 2022+, EV6, EV9.
Same forward-camera geometry — single-lens windshield-mounted, top-center, just below the rearview mirror — and the same long-range radar placement convention (radar hidden behind the front brand emblem on most trims or in a lower-bumper sensor pod on certain Silverado HD, Yukon, Escalade, Lyriq trims). The difference between Super Cruise and standard GM ADAS is the hands-free driving layer: Super Cruise adds an HD-map database, a lidar-mapped geo-restriction layer, an extended dynamic step to confirm hands-free driving readiness, and a DLC-learned GRBL handshake to confirm the HD-map geo-restriction is active. Without the GRBL handshake the car has no geo-restriction confirmation and hands-free driving will fail to engage.
Single-lens forward-facing windshield camera at top-center of the windshield, just below the rearview mirror (same mounting location as standard GM ADAS), plus a long-range millimeter-wave radar most commonly hidden behind the front Cadillac crest emblem (or in a lower-bumper sensor pod on certain Escalade and Lyriq trims). Short-range corner radars in the rear bumper corners on most 2022+ trims. Super Cruise adds an HD-map database with a lidar-mapped geo-restriction layer — the car must read the map and confirm coverage before hands-free driving will engage.
Available on Cadillac Escalade, CT5, and Lyriq (and select Chevy Bolt EUV, Silverado trims). Static calibration on the forward camera plus dynamic confirmation on a prescribed route plus long-range radar re-aim behind the Cadillac crest emblem (or the Chevy bowtie on Bolt EUV / Silverado) plus an extended dynamic step to confirm hands-free driving readiness plus a DLC-learned GRBL handshake to confirm HD-map geo-restriction is active and the hands-free driving system will engage. The GRBL handshake is its own separate step on top of the extended dynamic calibration — without it the car has no geo-restriction confirmation, and Super Cruise hands-free driving will fail to engage or engage in stretches where it should not.
Single-lens forward-facing windshield camera at top-center of the windshield, just below the rearview mirror. A separate long-range millimeter-wave radar hidden behind the front Chevy bowtie, GMC red, Cadillac crest, or Buick tri-shield on most trims (or in a lower-bumper sensor pod on certain Silverado HD, Yukon, Escalade, Lyriq trims). Short-range corner radars in the rear bumper corners on most 2022+ trims.
Chevy Safety Assist baseline trims (Silverado, Equinox, Tahoe, Suburban, Traverse base trims through model year 2022) and Buick Driver Confidence baseline trims (Enclave, Encore GX base trims) use static target calibration only — no driving required. GMC Pro Safety and Cadillac ADAS baseline trims (CT5, Escalade, Lyriq without Super Cruise) require static plus dynamic plus long-range radar re-aim behind the front brand emblem, but no GRBL handshake (no hands-free driving). 2022+ trims equipped with short-range corner radars across all four brands add a corner-radar aim step on top.
Every windshield-mounted ADAS camera gets recalibrated one of two ways. Chevy Safety Assist baseline trims (Silverado, Equinox, Tahoe, Suburban, Traverse base trims) and Buick Driver Confidence baseline trims (Enclave, Encore GX base trims) use static target calibration only. Cadillac ADAS (CT5, Escalade without Super Cruise, Lyriq base) and GMC Pro Safety require static plus dynamic; the long-range radar hidden behind the Chevy bowtie, GMC red, Cadillac crest, or Buick tri-shield is re-aimed as a separate required step. Super Cruise trims (Cadillac Escalade, CT5, Lyriq with hands-free package; select Chevy Bolt EUV and Silverado trims) add the extended dynamic step plus the DLC-learned GRBL handshake. 2022+ trims equipped with short-range corner radars add a corner-radar aim step on top.
Vehicle stays on a level lift, on level ground, in a controlled bay. A manufacturer-issued printed target board sits at a precise measured distance and height in front of the car. The scan tool drives the camera module through its re-learn. Result is geometry-precise to OEM tolerance. The right step for most Chevy Safety Assist baseline trims (Silverado, Equinox, Tahoe, Suburban, Traverse base trims through model year 2022) and most Buick Driver Confidence baseline trims (Enclave, Encore GX base trims).
A scan tool drives a prescribed road-driving routine at a prescribed speed on well-marked roads while the camera module re-learns where the lane lines and lead vehicles actually are. Required on top of static for most Cadillac ADAS trims (CT5, Escalade, Lyriq) and most GMC Pro Safety trims (Sierra, Yukon, Acadia). Super Cruise trims add an extended dynamic step to confirm hands-free driving readiness. The static step establishes geometry; dynamic confirms performance under real driving conditions.
Chevy Safety Assist, GMC Pro Safety, Cadillac ADAS, and Buick Driver Confidence forward-camera calibration — plus long-range radar re-aim behind the Chevy bowtie, GMC red, Cadillac crest, or Buick tri-shield where equipped, plus extended dynamic + DLC-learned GRBL handshake on Super Cruise trims (Cadillac Escalade, CT5, Lyriq, select Chevy Bolt EUV and Silverado), plus short-range corner-radar aim on 2022+ trims — is performed at the same appointment as the windshield replacement. No extra trip, no subcontracted handoff. You leave with documented evidence that Automatic Emergency Braking, Forward Collision Alert, Front Pedestrian Braking, Lane Keep Assist with Lane Departure Warning, Following Distance Indicator, IntelliBeam Auto High Beams, Adaptive Cruise Control, Rear Cross Traffic Alert, Lane Change Alert with Side Blind Zone Alert, Reverse Automatic Braking, HD Surround Vision, and (where equipped) Super Cruise hands-free highway driving are within GM tolerance.
Before we touch the glass, we scan your GM for stored Chevy Safety Assist / GMC Pro Safety / Cadillac ADAS / Buick Driver Confidence fault codes and confirm the exact recalibration procedure the OEM publishes for your model year and trim — including whether your vehicle is Super Cruise-equipped (most 2021+ Escalade Premium Luxury and Platinum, 2020+ CT5 Premium Luxury, 2023+ Lyriq, select 2022+ Chevy Bolt EUV and 2024+ Chevy Silverado trims) and whether the long-range millimeter-wave radar hidden behind the Chevy bowtie, GMC red, Cadillac crest, or Buick tri-shield is present and undisturbed. We use GM GDS2 / MVI / GM SPS / GMDI tooling to read the calibration state of the forward camera, the long-range radar, the short-range corner radars, and (on Super Cruise trims) the HD-map GRBL handshake state — the four diagnostics we reset during the calibration step.
We install OEM-spec glass with the correct mounting bracket geometry for your Silverado, Equinox, Tahoe, Suburban, Traverse, Sierra, Yukon, Acadia, Escalade, CT5, Lyriq, Enclave, or Encore GX. Aftermarket windshields without the proper bracket flatness create camera alignment errors that no amount of post-install calibration can fully correct. On Super Cruise-equipped Escalade, CT5, Lyriq (and select Chevy Bolt EUV and Silverado trims) we also confirm the long-range radar hidden behind the Cadillac crest (or Chevy bowtie) is undisturbed and that the HD-map geo-restriction is current before the GRBL handshake step — a stale HD-map database that cannot pass the GRBL handshake will block Super Cruise engage regardless of how clean the camera leg is.
GM published procedures differ across brands and trim tiers and they do not always line up. Chevy Safety Assist baseline trims and Buick Driver Confidence baseline trims use static target calibration only. Most Cadillac ADAS and GMC Pro Safety trims (and most chevrolet, Buick Driver Confidence Plus trims) require static plus dynamic — plus long-range radar re-aim behind the front emblem. Super Cruise trims require static plus dynamic plus long-range radar re-aim plus the extended dynamic step to confirm hands-free driving readiness plus the DLC-learned GRBL handshake to confirm HD-map geo-restriction is active. The 2022+ trims with short-range corner radars add a corner-radar aim step on top. We follow the GM GDS2 / MVI / GM SPS / GMDI published procedure family for whichever tier your vehicle falls into and document the resulting four-diagnostic cluster state on the post-calibration report.
You leave with a documented pre- and post-calibration report — showing the forward-camera module passed GM tolerance, the long-range millimeter-wave radar (behind the Chevy bowtie, GMC red, Cadillac crest, or Buick tri-shield) is within re-aim spec, the short-range corner radars (where equipped) have been aimed, and (on Super Cruise trims) the HD-map GRBL handshake has succeeded and the hands-free driving system will engage. This is your evidence that Automatic Emergency Braking, Forward Collision Alert, Front Pedestrian Braking, Lane Keep Assist with Lane Departure Warning, Following Distance Indicator, IntelliBeam Auto High Beams, Adaptive Cruise Control, Rear Cross Traffic Alert, Lane Change Alert with Side Blind Zone Alert, Reverse Automatic Braking, HD Surround Vision, and (where equipped) Super Cruise hands-free highway driving are operating on calibrated geometry.
