6.
Start and run the engine for a minimum of three minutes.
7. When instructed by T4, use the special tool to measure and record the height setting from each wheel center to the
calibrated level surface.
CAUTION: Set the ride height to NORMAL and wait until the system stops adjusting. This is indicated by
the NORMAL height symbol on the air suspension switch being illuminated and all other symbols being
extinguished.
CAUTION: The ride height measurements are made between the vehicle lower suspension arm fixings
and the flat, level surface. If the ride height calibration procedure is carried out on a vehicle lift, the
measurements must be made to a position at the same level as the vehicle lift platform.
CAUTION: Make sure the vehicle is not moved once it has been positioned to take measurements.
