Air suspension
Operates automatically when the
vehicle is driven. The air suspension
system constantly adjusts the ride
height according to the vehicle load.
Caution
To ensure safe operation of the air
suspension system, do not exceed the maximum permissible gross
vehicle weight rating. Refer to
identification plate 3 204 or the
vehicle documents.
For further information on the air
suspension system, refer to the
operating instructions supplied.

126Driving and operatingRemote control
When increased ground clearance orimproved vehicle access is required,the suspension can be raised or
lowered using the remote control.
Caution
Ensure there is adequate
clearance and that there are no
obstructions when adjusting the
suspension height.
The remote control unit is magnetic
and may be fixed to any metal part of the vehicle or stored in its holder.
With the engine running, press theappropriate button for 2 seconds to
adjust the suspension height.
Indicator light will flash intermittently
while height adjustment is in progress
and illuminates when complete.
If the ignition is switched on with
engine not running, the suspension
height can only be lowered.
Notice
Handle with care, protect from
moisture and high temperatures and
avoid unnecessary operation.
Pre-programmed settings
Adjusts the suspension height to one
of three pre-programmed positions.l:lowered positionk:normal positionj:raised positionCaution
If an obstacle is detected while
raising or lowering, the
suspension height is returned to the normal position after a delay.
This does not guarantee damage-
free operation. Ensuring sufficient
clearance and freedom from
obstacles is the responsibility of the driver.
Manual settings
Manual adjustment can only be
performed when the vehicle is
stationary.
Select by pressing h for 2 seconds,
then R to raise, or S to lower.
To exit, press any of the pre-
programmed buttons.
Notice
Obstacle detection is not available
during manual adjustment.
When a certain low speed is
exceeded or when the ignition is
switched off, height adjustment is deactivated automatically and the
suspension height is returned to the
normal position.
Service mode
When the vehicle is stationary, press
i for 5 seconds to put the vehicle into
service mode. The indicator light will
illuminate.
Page 129 of 239

Driving and operating127When service mode has been
activated, the air suspension master
switch must be turned off.
To exit service mode, press i again
for 5 seconds.
Fault
If a fault is detected, i will flash
intermittently. If service mode has
been activated and there is a fault, h,
S and R will flash simultaneously.
Have the cause of the fault remedied
by a workshop.Engine exhaust9 Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Diesel particle filter
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving without
any notification.
The filter is cleaned by periodically
burning off the soot particles at high
temperature. This process takes
place automatically under set driving
conditions. Autostop is not available
and fuel consumption may be higher
during this period. The emission of
smells and smoke during this process is normal.
Under certain driving conditions, e.g.
short distances, the system cannot
clean itself automatically.
If cleaning of the filter is required and
if previous driving conditions did not
enable automatic cleaning, it will be
indicated by illumination of control
indicator A 3 87. Seek the
assistance of a workshop
immediately.Caution
If the cleaning process is
interrupted, there is a risk of
provoking severe engine damage.
Cleaning takes place quickest at high engine speeds and loads.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
