Mercedes PRE-SAFE / Driver Assistance Package uses stereo camera + radar. Here's exactly what it means for your windshield replacement.

|---|---|---|
| PRE-SAFE Brake | Yes — stereo camera | Camera angle may shift |
| Active Lane Keeping Assist | Yes — stereo camera | Camera angle may shift |
| Active Blind Spot Assist | Radar + camera | Camera angle may shift |
| Distance Pilot DISTRONIC | Radar + camera | Camera angle may shift |
| Active Speed Limit Assist | Yes — camera reads signs | Camera angle may shift |

Mercedes-Benz requires calibration any time the windshield is removed on an ADAS-equipped GLS. The stereo camera + radar system is particularly sensitive — the dual-camera setup requires precise alignment.
For the X167 (2020+), calibration is mandatory — every trim has ADAS standard. For the X166 (2013–2019), it depends on your trim — not all X166 GLS models have the Driver Assistance Package.
Our recommendation: Given the GLS's higher replacement costs, insurance is almost always the best route. Comprehensive coverage covers glass and calibration with little or no out-of-pocket cost. We handle the entire claim for you.
