NOTE Risk of damagetothe chassis from
loweredvehicle level
If electronic levelcontrol is malfunctioningor
readjusts while youare driving, thevehicle
levelmay be lowered.

Drivecarefully.
The levelofthe vehicle depends on vehicle load
and theload distribution. Electronic levelcontrol
adjusts thelevel of therear axle automaticallyon
vehicles withanair-sprung rear axle.The vehicle
levelistherebyalwaysmaintained at thedriving
level, regardless of vehicle load. Driving dynamics
remain unaffected. The height difference
between thesides of thevehicle maybeupto
0.4 in (1 cm).
Electronic levelcontrol is notengine-dependent
and is onlyoperational when theignition is
switched on. The electronic levelcontrol com‐
pressor worksaudibly.

If thecompressor worksconstantly or starts
up severaltimes per minute, electronic level
control is malfunctioning.
Depending on thevehicle equipment, electronic
levelcontrol switches between manual and auto‐
matic mode depending on either thevehicle
speed or theposition of theparking brake.
If electronic levelcontrol switches depending on
vehicle speed, manual operation is automatically
activated when thevehicle is stationary. Youmay
raise or lowerthe vehicle level. If yousubse‐
quently drivefasterthan 6mph (10km/h), man‐
ual mode is automaticallydeactivated and auto‐
matic mode sets thevehicle level.
If electronic levelcontrol switches depending on
theparking brakeposition,manual mode is auto‐
maticallyactivated when theparking brakeis
applied. Youmay raise or lowerthe vehicle level
to load and unload. If yourelease theparking
brake, manual mode is automaticallydeactivated
and automatic mode sets thedriving level.
When working on thevehicle or changing a
wheel, youcan deactivateelectronic levelcontrol
(/ page126).
If electronic levelcontrol is malfunctioningorthe
vehicle levelistoo high or toolow,anaudible sig‐
nal sounds.
The drivingand steering characteristicsofthe
vehicle will be noticeably different. Electronic
levelcontrol adjusts thevehicle leveltothe nor‐
mal levelassoon as possible. Continue driving
carefullyuntil theaudible signal stops. Onlythen
is thevehicle at normal level.
Automatic mode and electronic levelcontrol
automaticallyswitchonagain to restorethe vehi‐
cle level, depending on theoption selected:
R
when theparking brakeisreleased
R
from speeds of approximately6mph
(10km/h)
If theelectronic levelcontrol compressor threat‐
ens to overheat, e.g. due to repeated raising or
lowering within ashortperiod, electronic level
control is deactivated. Youcan raise or lowerthe
vehicle levelagain afterapproximately
one minute.
Raising and lowering thevehicle level
Certain special equipmentenables other opera‐
tion options:
R
Ambulance: raising thevehicle levelabove
thedriving level(centerposition) is notpossi‐
ble. Only thelowest position and thedriving
levelcan be set.
R
Speed signal: in order to operateelectronic
levelcontrol, theparking brakemustnot be
applied. Electronic levelcontrol can be oper‐
ated manuallyupto6.2 mph(10 km/h).If
this speed is exceeded, driving levelwill be
setautomatically.
R
Castermodule, 30 min: electronic levelcon‐
trol can be operatedupto30min after
switching offthe ignition.
