What is an ADAS alignment and how does it work?

An ADAS alignment is a calibration of the components in an Advanced Driver Assistance System.

Vehicles equipped with ADAS rely on special sensors, cameras, and radar units that are mounted on the body that are able to detect lane markings, road features, and obstacles. Data from these sensors, along with that from steering and suspension sensors, help to enhance the driving experience and improve vehicle safety. ADAS attempts to do so by performing driver tasks, such as automated parallel parking, adaptive cruise control. It also might activate safety features, such as lane departure warnings, emergency braking, or pedestrian avoidance.

In order for these features of ADAS to work correctly, all of the sensors and electronics associated with the ADAS system must be calibrated and aligned correctly. Because the ADAS system can take control of your brake or steering systems during activation, all of the sensors and cameras must be set properly. For example, if a camera is not aligned as it should be, some features might not activate when needed - or they might cause more harm than good.


How is a an ADAS Alignment done?

The specific procedures a technician would follow for an ADAS alignment will differ somewhat from one vehicle make and model to the next. A general set of steps a technician would take include:

  • Perform a traditional four-wheel alignment on the vehicle to confirm camber, caster, and toe angles are within specifications
  • Inspect all cameras, sensors, and radar units for obvious signs of damage
  • Connect a diagnostic tool that can read data coming from each component in the system in order to confirm all electronic parts are reading and functioning correctly
  • Clean the vehicle's windshield to ensure a clear viewing window for the in-car camera
  • Clear the area around the vehicle to ensure a clutter-free environment during calibration, so the collision avoidance camera does not improperly calibrate to a foreign object
  • Place reflectors and reference tools in strategically located spots around the outside of the vehicle, per the manufacturer's alignment instructions
  • Follow all on-screen instructions on the diagnostic tool and complete the calibration/alignment process

How do I know if my vehicle needs an ADAS alignment?

Not all vehicles come equipped with ADAS, although it is becoming more popular on passenger vehicles. Modern ADAS incorporates a variety of sensors, cameras, and radar units. When they are functioning properly, ADAS can be a valuable tool to provide drivers with potentially life-saving maneuvers and other services. When working incorrectly, on the other hand, the system can either not function at all, or might actually be counterproductive. Examples of problems that indicate an inspection and alignment of your ADAS include:

The brakes are applied automatically when no emergency or danger exists

The brakes do not engage automatically when an emergency or danger is present

You get a warning light or sound from the ADAS even when no particular safety issue exists

The check engine light comes on

Other questions customers ask

What are the disadvantages of ADAS?
ADAS is a system that incorporates several features to assist a driver by sensing the world around the vehicle and taking action automatically to (for instance) avoid a crash, maintain a speed or distance from another vehicle, and stay in a lane on the roadway. ADAS can malfunction, however. And when it does, it might pull your vehicle across the centerline of the road or onto the shoulder. It might apply the brakes even when there is no danger simply because a radar malfunctioned or sensed an object that does not really need to be avoided.
What happens if I don't calibrate my windshield?
If you get your windshield replaced on an ADAS equipped vehicle and do not have the system recalibrated, the collision avoidance camera might not read correctly and malfunction. When this happens, ADAS might work incorrectly and create a dangerous driving condition.
Do all new cars have ADAS?
Nearly every new vehicle has some form of ADAS, whether something as simple as a lane departure warning chime when you start veering off the road, all the way up to vehicles that parallel park autonomously.
