WHAT IS INVOLVED IN A WHEEL ALIGNMENT SERVICE?
A wheel alignment will include inflating your tires to the correct air pressure, inspecting the steering and suspension system, aligning the vehicle to manufacturer's specifications and a test drive to ensure all systems are aligned to the straight-ahead position and working properly.
If yourcar manufacturer requires the recalibrations of features associated with Advanced Driver Assistance Systems as part of the alignment service, a Safety Systems Alignment will be required to recalibrate cameras, sensors and radars along with a test drive to ensure these systems are working properly.
Failure to perform OEM required recalibrations may cause a vehicle to operate erratically, which may contribute to collisions or other safety issues.
HOW DO I KNOW IF MY VEHICLE REQUIRES SAFETY SYSTEMS RECALIBRATION?
The most common manufacturers that may require a recalibration of ADAS features as part of an alignment service are:
• BMW • Audi • Ford • Lincoln • Jeep • Kia • Dodge • Subaru • Volkswagen • Chrysler • Porsche • Chevrolet • GMC • Hyundai • Infinity • Lexus • Mercedes Benz • Toyota
*Most of our locations are equipped with the latest technology to perform Safety System Alignments but capability varies per location.
