Hyundai Highway Driving Assist (Elantra, Sonata, Tucson, Santa Fe, Palisade, Ioniq 5, Kona) and Kia Highway Driving Assist (Forte, K5, Sportage, Sorento, Telluride, EV6, Seltos) both depend on a single forward-facing camera mounted at the top of the windshield — and on HDA-equipped trims, a millimeter-wave radar hidden behind the Hyundai "H" or Kia "K" emblem in the grille. Removing that windshield breaks the camera geometry. Legendary Auto Glass performs Hyundai and Kia forward-camera static and dynamic calibration in-house, plus grille-radar re-aim behind the Hyundai "H" or Kia "K" emblem where equipped — same appointment as your windshield replacement, OEM-spec glass, documented pre- and post-scan report.

Hyundai Highway Driving Assist (HDA) and Kia Highway Driving Assist (HDA) 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, and pairs with a millimeter-wave radar module hidden behind the Hyundai "H" or Kia "K" emblem in the grille on most HDA-equipped trims from 2022 onward. Both brands publish the geometry problem in similar terms: the camera and the radar are paired inputs that both feed Highway Driving Assist, Smart Cruise Control, Forward Collision-Avoidance Assist, and Lane Following Assist, and those inputs are calibrated to within a fraction of a degree at the factory. When we remove your windshield, the camera calibration is broken. On HDA trims (2019 Palisade, 2019 Telluride, most 2022+ HDA and SCC trims, EV lineup), the radar calibration is also disturbed by anything that touches the grille area, including the kind of bumper cover removal that frequently happens alongside a windshield replacement.
Single-lens forward-facing camera in a bracket at the top-center of the windshield, just below the rearview mirror — the same physical location on Elantra, Sonata, Tucson, Santa Fe, Palisade, Ioniq 5, Kona (Hyundai) and Forte, K5, Sportage, Sorento, Telluride, EV6, Seltos (Kia). Hyundai SmartSense and Kia Drive Wise share the same published mounting geometry across all HDA-equipped trims from 2019 onward. The millimeter-wave radar sits behind the Hyundai "H" emblem in the grille on most Hyundai HDA-equipped trims (2019 Palisade and broader from 2022 onward) and behind the Kia "K" emblem in the grille on most Kia HDA-equipped trims (2019 Telluride and broader from 2022 onward). The Driver Attention Warning system uses a separate in-cabin IR camera on some 2022+ Santa Fe, Sonata (Hyundai), Sorento, and Telluride (Kia) trims and has its own alignment step.
Any windshield removal and replacement, windshield bracket adjustment, suspension work, front-end collision repair, wheel-alignment change, or anything that moves the grille-mounted millimeter-wave radar invalidates the factory calibration. Hyundai and Kia do not separately mark which leg was tripped; both OEMs publish the procedure as "recalibrate the camera whenever the windshield is disturbed, and re-aim the grille-mounted radar whenever the bumper or grille has been disturbed." The model-year matrix determines which static / dynamic / radar-aim steps apply — most 2022+ HDA trims and the EV lineup (Ioniq 5, Ioniq 6, EV6, EV9) require the static + dynamic + radar re-aim stack; earlier SmartSense + Drive Wise trims (2019-2021) without HDA use static only.
Hyundai and Kia do not always illuminate a dashboard warning when calibration is incorrect — particularly for partial miscalibrations where the camera is only slightly off-axis. Forward Collision-Avoidance Assist will brake at the wrong distance or for the wrong target. Smart Cruise Control will pace the wrong lead vehicle, including cars in adjacent lanes during a lane change. Highway Driving Assist will steer toward an off-center lane position. Navigation-based Smart Cruise Control (NSCC) can apply phantom braking at interchanges and curves because the speed-set logic is using a miscalibrated forward-camera horizon. Lane Following Assist will track the wrong lane center. Driver Attention Warning can become erratic and either lock out the system or fail to alert a drowsy driver. Safe Exit Warning and Rear Cross-Traffic Collision-Avoidance Assist can produce false alerts or fail to alert. Most drivers will not feel anything is wrong until the system fails to react in a real emergency.
When we remove your Hyundai or Kia 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 Hyundai or Kia 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 — and grille-radar re-aim where radar is equipped — re-teach the camera and the radar where straight-ahead is so Highway Driving Assist, Smart Cruise Control, Navigation-based Smart Cruise Control, Forward Collision-Avoidance Assist, Lane Following Assist, Blind-Spot Collision-Avoidance Assist, Rear Cross-Traffic Collision-Avoidance Assist, Safe Exit Warning, and Driver Attention Warning react on the road the car actually sees — not a road that is several feet offset from reality. The radar re-aim is a separate required step on every Hyundai HDA trim and every Kia HDA trim where the millimeter-wave radar is equipped; skipping it leaves the pre-collision and cruise logic 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 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 matter. Generic "ADAS calibration" without model-specific protocol is how the radar re-aim behind the Hyundai or Kia emblem gets skipped or done wrong.
Single-lens forward-facing windshield camera in a bracket at the top-center, just below the rearview mirror — shared mounting geometry across Elantra, Sonata, Tucson, Santa Fe, Palisade, Ioniq 5, Kona (Hyundai) and Forte, K5, Sportage, Sorento, Telluride, EV6, Seltos (Kia). A separate millimeter-wave radar sits behind the Hyundai "H" or Kia "K" emblem in the grille on every HDA-equipped trim from 2022 onward. The Hyundai "H" emblem and Kia "K" emblem hide the radar in the same grille location on both brands. Driver-monitoring IR camera on some 2022+ Santa Fe, Sonata, Sorento, Telluride trims as a separate alignment step.
Static calibration only on 2019-2021 SmartSense + Drive Wise trims without HDA. Static plus dynamic plus grille-radar re-aim required 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. Radar re-aim behind the Hyundai "H" or Kia "K" emblem is a separate required step whenever the grille area has been disturbed. Navigation-based Smart Cruise Control (NSCC) on HDA trims depends on the camera leg of calibration — phantom braking at interchanges is a common symptom if the leg is skipped.
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 on Chevy/Cadillac, long-range radar hidden behind the front emblem or in a lower-bumper pod, plus short-range corner radars on most 2022+ trims. Super Cruise trims add HD-map geo-restriction plus DLC handshake.
Static calibration only on Chevy Safety Assist baseline trims. Static plus dynamic plus long-range radar re-aim on Super Cruise trims with extended dynamic + GRBL handshake. Short-range corner-radar aim on 2022+ trims where equipped.
Same forward-camera geometry — single-lens windshield-mounted, top-center, just below the rearview mirror — and the same grille-radar placement convention (radar hidden behind the brand emblem in the grille). The difference between Hyundai and Kia is the model-year rollout: Hyundai launched HDA on the 2019 Palisade and broadened across Sonata, Tucson, Santa Fe, Elantra, Kona, Ioniq 5 from 2020-2022. Kia launched on the 2019 Telluride and broadened across K5, Sportage, Sorento from 2021-2022 and EV6, EV9 from 2022-2023.
Single windshield-mounted forward camera at the top-center of the windshield plus a millimeter-wave radar hidden behind the Hyundai "H" emblem in the grille on most Hyundai HDA trims from 2022 onward. Driver Attention Warning IR camera added on some 2022+ Santa Fe and Sonata trims with its own alignment step.
Hyundai launched HDA on the 2019 Palisade. Static calibration only on 2019-2021 SmartSense trims without HDA (Elantra, Sonata, Tucson, Santa Fe, Kona). Static plus dynamic plus grille-radar re-aim behind the Hyundai "H" emblem required on 2020+ Sonata, 2022+ Tucson, 2022+ Santa Fe, 2022+ Elantra, 2022+ Kona, and the EV lineup (Ioniq 5 2022+, Ioniq 6 2023+) where radar is equipped. Navigation-based Smart Cruise Control (NSCC) on HDA trims adds a map-data-dependent speed-set layer that relies on a calibrated forward-camera horizon.
Single windshield-mounted forward camera at the top-center of the windshield plus a millimeter-wave radar hidden behind the Kia "K" emblem in the grille on most Kia HDA trims from 2022 onward. Driver Attention Warning IR camera added on some 2022+ Sorento and Telluride trims with its own alignment step.
Kia launched HDA on the 2019 Telluride. Static calibration only on 2019-2021 Drive Wise trims without HDA (Forte, Seltos, pre-2022 K5 and Sportage). Static plus dynamic plus grille-radar re-aim behind the Kia "K" emblem required on 2022+ Sorento, 2022+ Sportage, 2022+ K5, and the EV lineup (EV6 2022+, EV9 2023+) where radar is equipped. Forte and Seltos top trims use Forward Collision-Avoidance Assist with Smart Cruise Control without the full HDA highway steering layer but still require forward-camera calibration after windshield replacement.
Every windshield-mounted ADAS camera gets recalibrated one of two ways. Most 2019 through 2021 Hyundai SmartSense and Kia Drive Wise trims without HDA use static target calibration only. 2022 and newer Hyundai HDA trims and most Kia HDA trims — plus the full Hyundai and Kia EV lineup (Ioniq 5, Ioniq 6, EV6, EV9) — pair static with a dynamic road-driven step, and add a separate grille-radar re-aim behind the Hyundai "H" or Kia "K" emblem.
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 2019-2021 SmartSense and Drive Wise trims without HDA — including Hyundai Elantra, Sonata, Tucson, Santa Fe, Kona and Kia Forte, Seltos, K5 (pre-2022), Sportage (pre-2022).
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 2022+ Hyundai HDA-equipped trims (Palisade, Sonata, Tucson, Santa Fe, Elantra 2022+, Ioniq 5) and 2022+ Kia HDA-equipped trims (Telluride, Sorento, Sportage 2022+, K5 2022+, EV6, EV9). The static step establishes geometry; dynamic confirms performance under real driving conditions.
Hyundai SmartSense and Kia Drive Wise forward-camera calibration — and grille-radar re-aim behind the Hyundai "H" or Kia "K" emblem on HDA-equipped trims (2019 Palisade, 2019 Telluride, 2022+ HDA trims and the EV lineup) — is performed at the same appointment as the windshield replacement. No extra trip, no subcontracted handoff. You leave with documented evidence that Highway Driving Assist, Smart Cruise Control, Forward Collision-Avoidance Assist, Lane Following Assist, Blind-Spot Collision-Avoidance Assist, and Rear Cross-Traffic Collision-Avoidance Assist are within Hyundai or Kia tolerance.
Before we touch the glass, we scan your Hyundai or Kia for stored SmartSense / HDA or Drive Wise / HDA fault codes and confirm the exact recalibration procedure the OEM publishes for your model year — including whether your specific Hyundai trim is HDA-equipped (most 2022+ Palisade, Sonata, Tucson, Santa Fe, Elantra 2022+, Ioniq 5, and 2019 Palisade), or your Kia trim is HDA-equipped (2019 Telluride, 2022+ Sorento, 2022+ Sportage, 2022+ K5, EV6, EV9). We also confirm whether the grille-mounted millimeter-wave radar behind the Hyundai "H" or Kia "K" emblem is equipped and undisturbed, and whether the Driver Attention Warning IR camera on your trim (some 2022+ Santa Fe, Sonata, Sorento, Telluride) needs its own separate alignment step.
We install OEM-spec glass with the correct mounting bracket geometry. Aftermarket windshields without the proper bracket flatness create camera alignment errors that no amount of post-install calibration can fully correct. On HDA-equipped trims we also confirm the grille-mounted millimeter-wave radar behind the Hyundai "H" or Kia "K" emblem is undisturbed and ready for re-aim — the HDA modal procedure on 2019 Palisade and 2019 Telluride requires the radar-aim datum to match the OEM-published reference before the dynamic step will pass.
Hyundai and Kia procedures differ by generation and trim — and they do not always line up. Most 2019 through 2021 SmartSense and Drive Wise trims without HDA use static target calibration only. 2022 and newer Hyundai HDA trims (Palisade, Sonata, Tucson, Santa Fe, Elantra 2022+, Ioniq 5) and 2022+ Kia HDA trims (Telluride, Sorento, Sportage 2022+, K5 2022+, EV6, EV9) require static plus dynamic procedures, and the grille-mounted millimeter-wave radar behind the Hyundai "H" or Kia "K" emblem is re-aimed to OEM spec using OEM-compatible tooling. Navigation-based Smart Cruise Control (NSCC) on HDA-equipped trims is then verified against the calibrated forward-camera horizon so the map-data speed-set layer operates on accurate lane geometry.
You leave with a documented pre- and post-calibration report — showing the SmartSense / Drive Wise or HDA modules passed Hyundai or Kia tolerance, which sub-systems were calibrated (camera-only on 2019-2021 SmartSense + Drive Wise trims; camera plus dynamic plus grille-radar re-aim on 2022+ HDA trims and the EV lineup), and the system status at handoff. This is your evidence that Highway Driving Assist, Smart Cruise Control, Navigation-based Smart Cruise Control, Forward Collision-Avoidance Assist, Lane Following Assist, Blind-Spot Collision-Avoidance Assist, Rear Cross-Traffic Collision-Avoidance Assist, and Safe Exit Warning are operating on calibrated geometry.
