wheel arches when the vehicle is being
lowered.
& WARNING Risk of injury due to the jack
tipping over
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.
Before raising the vehicle, press the
#
Service button on the remote control for
the air suspension.
This prevents the vehicle level from being
automatically readjusted or manually
raised or lowered.
& WARNING Risk of accident due to lowered
or raised chassis frame
If the chassis frame is adjusted, the braking
and driving characteristics can be severely
impaired. You could also exceed the permissi-
ble vehicle height.
Adjust the driving level before driving off.
#
& WARNING Risk of accident due to a mal-
function of electronic level control
The vehicle level may be too high, too low or
asymmetrical.
The driving and steering characteristics of the
vehicle may be noticeably different.
Adapt your driving style to the changed
#
driving characteristics.
Stop, paying attention to road and traffic
#
conditions.
Consult a qualified specialist workshop.
#
* NOTE Risk of damage to the chassis from
lowered vehicle level
If electronic level control is malfunctioning or
readjusts while you are driving, the vehicle
level may be lowered.
Pay attention to the road conditions and
#
ensure there is sufficient ground clear-
ance.
Drive carefully.
#
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 0.4 in (1 cm).
Electronic level control is not engine-dependent
and is only operational when the vehicle is
switched on. The electronic level control compres-
sor 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 6 mph (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 auto-
matically 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
( page 129).
/
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 vehi-
cle 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 nor-
mal level.
To restore the vehicle level, automatic mode and
electronic level control automatically switch on
again depending on the option selected:
