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.

moving the selector lever repeatedly
at short intervals.
Stopping the vehicle
In automatic or manual mode,
first gear is engaged and the clutch is
released when the vehicle is
stopped.In R, reverse gear remains
engaged.
When stopping on gradients, engage parking brake or depress the foot
brake.To prevent overheating of the
clutch, an intermittent audiblewarning may sound as a signal to
depress the foot brake or apply the
parking brake.
Switch off engine if stopping for a
lengthy period, e.g. in traffic jams.
When the vehicle is parked and the
driver's door is opened, a warning
chime will sound if neutral is not
selected or the foot brake has not
been depressed.
Engine braking
Automatic mode
When driving downhill, the manual transmission automated does not
shift into higher gears until a fairly
high engine speed has been
reached.It shifts down in good time
when braking.
Manual mode
To utilise the engine braking effect,
select a lower gear in good time when
driving downhill.

116Driving and operating
Rocking the vehicleRocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud, snow or a hole.Move the
selector lever between R and A/M (or
between + and -) in a repeat pattern,
while applying light pressure to the
accelerator pedal.Do not race the
engine and avoid sudden
acceleration.
Parking
Apply the parking brake.The most recently engaged gear (see
transmission display) remains
engaged.With N, no gear is engaged.
When the ignition is switched off, the
transmission no longer responds to
movement of the selector lever.
If the ignition is not switched off, or the
parking brake has not been applied, a warning chime will sound upon
opening the driver's door.
Manual mode If a higher gear is selected when the
engine speed is too low, or a lower
gear when the speed is too high, theshift is not executed. This prevents
the engine from running at too low or
too high an engine speed.
If engine speed is too low, the
transmission automatically shifts to a
lower gear.
If engine speed is too high, the
transmission only switches to a higher gear via kickdown.

118Driving and operatingBrakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when you depress the
brake pedal firmly. You need to use
considerably more force for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing your journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 79.
If the brake pads wear to a
predetermined point, the braking
system will require inspection. Seek
the assistance of a workshop.
Control indicator F 3 80.Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.
ABS starts to regulate brake pressure as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
Control indicator u 3 80.
Fault
If control indicators u and A
illuminate with the messages CHECK
ABS and CHECK ESP in the Driver
Information Centre, there is a fault in the ABS. The brake system remains
operational but without ABS
regulation.9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
If control indicators u, A , R and
C illuminate, the ABS and ESP are
deactivated and the message
BRAKING FAULT is shown in the
Driver Information Centre. Seek the
assistance of a workshop.
Have the cause of the fault remedied
by a workshop.
