Note:
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 control unit.
Change of cable harness.
When adjusting level the height shall be measured with a tape measure, hook the tape measure in the middle of the rim flange at the bottom and measure up to the fender's edge.
The adjustment method may absolutely not be interrupted!
Test conditions:
Before level adjustment is performed the motor must be turned on and off so that the air suspension is adjusted.
Any stresses in the chassis are released by rolling the vehicle back and forth for a short time.
Battery voltage above 12V.
Ignition on.
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.
Procedure:
Start the function.
Follow the instructions in the program.
After completed adjustment the tire pressure monitoring (see function in the ABS-system) must be initiated again.
