DISABLING/ENABLING ELECTRONIC LEVEL CONTROL

Adjusting Car To Normal Level (Air Suspension)

1. If air suspension accumulators of the air suspension are filled, only the ignition has to be switched on. If air pressure in the accumulators is too low, the compressor comes on and loads the battery. In this case, the battery must be charged, or the engine must be started.
2. Stop the vehicle and apply the brake.
3. Close vehicle doors.
4. Tap the right-hand rocker switch in the center console in the appropriate direction until the vehicle has reached the low level. Then set the vehicle to the normal level.
5. The middle indicator light next to the rocker switch is on permanently. If a further indicator light should come on, a different level is adjusted.

Note. To avoid controlling the air suspension level during a wheel alignment check/adjustment, switch the level control off during the alignment. Switch it on again after work is completed.

Switching Off Electronic Level Control (Air Suspension)

1. BEFORE switching off air suspension, adjust car to normal level. See «Adjusting Car To Normal Level (Air Suspension)»(ref-170237-S00702932932005011200000) .
2. Switch on ignition, with engine off.
3. Push rocker switch forwards for 5-10 seconds. The message "Car May Now Be Lifted" appears in the variable control display of the instrument panel.
