108Driving and operatingIdle speed control
To increase the idle speed press the
switch. After a few seconds the
function will be activated.
The function will be deactivated
when:
■ The clutch pedal is depressed
■ The accelerator pedal is depressed
■ MTA is not in neutral N
■ Vehicle speed is above 0 mph
■ Control indicator A, W or C

To increase or decrease the fast idle
speed rate, consult a workshop.
Overrun cut-off
The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but accelerator is released.
Stop-start system The stop-start system helps to save
fuel and to reduce the exhaust
emission. When conditions allow, it
switches off the engine as soon as the
vehicle is at low speed or standstill,
e.g. at a traffic light or in a traffic jam.
It starts the engine automatically as
soon as the clutch is depressed. A vehicle battery sensor ensures that
an Autostop is only performed if the
vehicle battery is sufficiently charged
for a restart.
Activation The stop-start system is available assoon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.Deactivation
Deactivate the stop-start system
manually by pressing the stop-start
Î button. LED in the button
illuminates when the system is
deactivated.
Autostop
If the vehicle is at low speed or
standstill, activate an Autostop as
follows:
■ depress the clutch pedal
■ shift the selector lever to N
■ release the clutch pedal

Master switchCaution
The air suspension system must
be switched off when the vehicle is being towed, jump‐started, raised
off the ground or transported.
Do not switch off the air
suspension system when driving.
The master switch is located on the
door pillar.
Remote control
When increased ground clearance or
improved vehicle access is required,the suspension can be raised or
lowered using the remote control.
The remote control unit is magnetic
and can be fixed to any metal part of
the vehicle.
With the ignition switched on, press
the appropriate button for 2 seconds
to adjust the suspension height.
Indicator light will flash intermittently
while height adjustment is in progress
and illuminates when complete.
Handle with care, protect from
moisture and high temperatures and
avoid unnecessary operation.
Pre-programmed settings Adjusts the suspension height to oneof three pre-programmed positions.
The buttons are only functional when
the engine is running.l=lowered positionk=normal positionj=raised position
Manual settings
Manual adjustment can only be
performed when the vehicle is
stationary.
Select by pressing button h for 2
seconds, then button R to raise, or
button S to lower.
To exit, press any of the pre-
programmed buttons.
When the vehicle is moving, manual
adjustment will exit automatically. If

112Driving and operating
Service modePress button i for 5 seconds to put
the vehicle into service mode. The indicator light will illuminate. When
service mode has been activated, the
air suspension master switch must be turned off.
To exit service mode, press button
i again for 5 seconds.
Fault If a fault is detected, i button will
flash intermittently. If the service
mode has been activated and there is a fault h, S and R buttons 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
and 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 79. Seek the
assistance of a workshop immediately.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
Page 115 of 201

Driving and operating113Caution
Fuel grades other than those listedon page 3 127, 3 174 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
If control indicator Z flashes, the
permitted emission limits may be
exceeded. Lift your foot off the
accelerator until Z stops flashing and
is steadily illuminated. Contact a
workshop immediately.
Malfunction indicator light 3 79.Manual transmission

stationary depress the clutch pedal, pull up the collar on the selector lever
and engage the gear.
If the gear does not engage, set the
lever in neutral, release the clutch
pedal and depress again; then repeat
gear selection.
Do not slip the clutch unnecessarily.
When operating, depress the clutch pedal completely. Do not use the
