116Driving and operatingEngine exhaust9Danger
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 80. 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.Caution
Fuel grades other than those listed on page 3 132, 3 185 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.

118Driving and operatingManual transmission

dependent on driving conditions.
To engage manual mode, move the
selector lever towards A/M. The
current gear will appear in the
transmission display.
To engage first gear, depress foot
brake and move selector lever
towards + or -. Shift to a higher or
lower gear by moving selector lever to
+ or -. Gears can be skipped by
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.Rocking the vehicle
Rocking 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.

120Driving and operatingManual modeIf a higher gear is selected when the
engine speed is too low, or a lower
gear when the speed is too high, the
shift 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.Electronic driving

effected in manual mode.Fault
In the event of a fault, control indicator
W is shown in the transmission
display. Continued driving is possible
provided the vehicle is driven with
care and anticipation.
Have the cause of the fault remedied
by a workshop.
Interruption of power
supply The clutch is not disengaged if there
is an interruption of the power supply
when a gear is engaged. The vehicle
cannot move.
If the vehicle battery is discharged,
start the vehicle using jump leads
3 171.
If the cause of the fault is not a discharged vehicle battery, seek the
assistance of a workshop.
If neutral cannot be selected, the
vehicle must only be towed with the drive wheels raised off the ground
3 174.
Towing the vehicle 3 174.Brakes
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.

prevents the wheels from locking.

124Driving and operatingRide control systems
Traction Control system
The Traction Control system (TC) is a
component part of the Electronic
Stability Program (ESP® Plus
) which
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
TC is operational as soon as the
ignition is switched on and control
indicator b extinguishes in the
instrument cluster. A corresponding
message also appears in the Driver
Information Centre 3 84.
