When lowering the vehicle, other people could become trapped if their limbs are between the vehicle body and the tyres or underneath the vehicle.
If you park a vehicle with air suspension, the air suspension can remain active for up to an hour, even if the vehicle is switched off. If you then raise the vehicle using the jack, the air suspension will attempt to even out the vehicle level.
The jack can tip over.
This prevents the vehicle level from being automatically readjusted or manually raised or lowered.
Modifying the vehicle frame may greatly impair braking and handling characteristics. It could also result in exceeding the permissible height for the vehicle.
The vehicle level may be too high, too low or asymmetrical.
The driving and steering characteristics of the vehicle may be noticeably different.
If electronic level control is malfunctioning or readjusts while you are driving, the vehicle level may be lowered.
The level of the vehicle depends on vehicle load and the load distribution. Electronic level control adjusts the level of the rear axle automatically on vehicles with an air-sprung rear axle. The vehicle level is thereby always maintained at the driving level, regardless of vehicle load. Driving dynamics remain unaffected. The height difference between the sides of the vehicle may be up to 1 cm.
Electronic level control is not engine-dependent and is only operational when the vehicle is switched on. The electronic level control compressor works audibly.
If the compressor works constantly or starts up several times per minute, electronic level control is malfunctioning.
Depending on the vehicle's equipment, electronic level control switches between manual mode and automatic mode. This is dependent on the driving speed or the parking brake position.
If electronic level control switches depending on vehicle speed, manual operation is automatically activated when the vehicle is stationary. You may raise or lower the vehicle level. If you subsequently drive faster than 10 km/h, manual mode is automatically deactivated and automatic mode sets the vehicle level.
If electronic level control switches depending on the parking brake position, manual mode is automatically activated when the parking brake is applied. You may raise or lower the vehicle level to load and unload. If you release the parking brake, manual mode is automatically deactivated and automatic mode sets the driving level.
When working on the vehicle or changing a wheel, you can deactivate electronic level control More.
If electronic level control is malfunctioning or the vehicle level is too high or too low, a warning tone sounds.
The driving and steering characteristics of the vehicle will be noticeably different. Electronic level control adjusts the vehicle level to the normal level as soon as possible. Drive on carefully until the warning tone stops. Only then is the vehicle at normal level.
when the parking brake is released
from speeds of approximately 10 km/h
If the electronic level control compressor is in danger of overheating, for example, due to repeated raising or lowering within a short period, electronic level control is deactivated. You can raise or lower the vehicle level again after a few minutes.
