What changes the price for a Mercedes GLS450

• Windshield-mounted camera. On the GLS450, Mercedes-Benz Driver Assistance uses a multifunction camera mounted near the rearview mirror; Mercedes-Benz requires the multifunction camera to be calibrated when the windshield is replaced, with a XENTRY diagnostic scan.
• Calibration is its own charge. Where a GLS450 has a windshield camera it is calibrated after the glass is set; what ADAS recalibration costs explains the range.

Mercedes Benz GLS450: repair or replace?

A chip smaller than a quarter or a crack shorter than about three inches can usually be repaired — faster and far cheaper than a full replacement. Replacement is the safer choice when the damage is longer than a dollar bill, sits in the driver’s line of sight, reaches the edge of the glass (which weakens the whole windshield), or goes through both layers. A qualified shop can confirm which option your Mercedes Benz GLS450 qualifies for.

Does insurance cover a Mercedes Benz GLS450 windshield?

Whether insurance covers your Mercedes Benz GLS450 windshield depends on your comprehensive coverage and deductible. A few states require insurers to waive the glass deductible entirely, and some insurers waive it for small chip repairs. See our guides to states with zero deductible for comprehensive glass claims and states with glass endorsement coverage to check the rules in your state.
