Before adjusting your headlamps, you must make
sure that the air suspension has been adjusted to
the proper ride height. In order to do this:

2. Make sure the air suspension switch in the
luggage compartment is in the ON position.
3. Turn the ignition key to the ON position.
4. Open and close the driver's door to allow the
air suspension to fully level.
