This function is used to make the height level sensors operational, these are connected to the ICM control unit.
Note:
If the optional equipment Xenon headlights is installed on the vehicle, then height level sensors are installed on the wheels left front and left rear. Among other things, height level values are used for light width control of the Xenon headlights, therefore it is important to check the light setting after completed level adjustment.
Level adjustment to make the height level sensors operational is required if the following jobs have been done on the vehicle:
Change of height level sensors.
Change of ICM control unit.
Failure of level sensors in ICM control unit.
Height level sensors are made operational via diagnosis, therefore it is not necessary to measure the height with a tape measure.

The vehicle must stand on level ground.
The vehicle's current load may not be changed. Doors may not be opened and the engine may not be started. This may lead to incorrect settings in the chassis.
