The instrument panel displays a message, and may also illuminate the general or critical warning lamps if adaptive dynamics develops a system fault. See OVERVIEW.
In the event of a system fault, some reduction in ride comfort may be experienced. If the fault persists, consult a retailer/authorized repairer.
ELECTRONIC AIR SUSPENSION LIMITATIONS
The electronic air suspension system:
- Does not raise the vehicle if there are insufficient air reserves in the system. Insufficient air reserves may occur due to frequent height adjustments within a short period of time. Run the engine without making further suspension height requests to replenish the air in the system.
- May not operate if the engine is not running.
- Operates without the engine running if:
- The auto stop/start system switches off the engine.
- A request to lower the suspension is made within one minute of the vehicle’s ignition being switched off.
- A height change is canceled.
- The rear height adjust feature is operating.
- Stops operating shortly after a door is opened. If the door is closed within 90 seconds, the operation resumes.
- Only lowers the vehicle when a door is open if sufficient air reserves are available to return it to its original height.
