Notice
In the event of an accident with
airbag deployment, the engine is
turned off automatically if the vehicle
comes to a standstill within a certain time.
108Driving 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 and may
take up to 25 minutes. Typically it
needs 15 minutes. 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 the cleaning of the filter is required
and if previous driving conditions did
not enable automatic cleaning, it will
be indicated by control indicator %.
Depending on version, a warning
message may also appear in the
Driver Information Centre 3 80.
Control indicator % illuminates when
diesel particle filter is full. Start cleaning process as soon as possible to avoid damage to the engine.
Cleaning process To activate cleaning process,
continue driving, keep engine speed
above 2000 rpm. Shift down if
necessary. Diesel particle filter
cleaning is then started.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.
Control indicator % extinguishes as
soon as the self-cleaning operation is
complete.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
Caution
Fuel grades other than those listed on pages 3 120, 3 166 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of
110Driving and operatingManual transmission

The manual transmission automated (MTA) permits manual (manual
mode) or automatic gear shifting
(automatic mode), both with
automatic clutch control.
Transmission display
Shows the mode and current gear.
Starting the engine Depress the foot brake when starting
the engine.
If the foot brake is not depressed, a
warning message appears in the
Driver Information Centre together
with a warning chime 3 86 and the
engine cannot be started.
Notice
The volume of the warning chime can also be adjusted via the Driver
Information Centre 3 80.
When the foot brake is depressed, the
transmission automatically shifts to
N (neutral) and the engine can be
started. There may be a slight delay.
Autostop
During an Autostop, if the gearshift
lever is in position N, select another
gear, otherwise release the brake
pedal or move the lever to +, – or R to
enable an automatic restart of the
engine.

The driver will be alerted to an
incorrect gear selection by an audible warning chime in conjunction with a
message in the Driver Information
Centre 3 80. The system will
downshift, selecting the most
appropriate gear automatically.
If R is selected, reverse gear is
engaged. The vehicle starts to move
when the foot brake is released. To
start off quickly, release the foot brake
and accelerate immediately after
engaging a gear.
Move the selector lever towards A/M
to engage automatic mode; the
transmission shifts to other gears
automatically, dependent on driving
conditions.
To engage manual mode, move the
selector lever towards A/M. The
current gear will appear in the
transmission display.
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 audible
warning chime 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.
112Driving 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 engine speed is too low, the
transmission automatically shifts to a
lower gear.In manual mode, no automatic
shifting to a higher gear takes place at high engine revolutions. If engine
speed is too high, the transmission
only switches to a higher gear via
kickdown 3 112.
When gearshifting is recommended
to improve fuel economy, control
indicator [ or Ò illuminates in the
Driver Information Centre 3 76.
Electronic driving
programmes
Eco mode EWhen automatic mode is engaged,
the Eco mode can be selected to
reduce fuel consumption.
Eco mode selects the most suitable gear depending on the speed of the
vehicle, the engine speed and the
intensity with which the accelerator is pressed.
Activation
Press the E button on the selector
lever housing. Control indicator E is
shown in the transmission display to
indicate activation.
Deactivation
Eco mode is switched off by:
■ pressing the E button again,
■ switching to manual mode.
In order to protect the transmission at
extremely high clutch temperatures,
an intermittent audible warning chime may sound. In such cases, depress
the foot brake, select N and apply the
parking brake to allow the clutch to
cool down.
Driving and operating113
KickdownIf the accelerator pedal is pressedpast the pressure point, the
transmission shifts to a lower gear depending on engine speed. Full
engine power is available for
acceleration.
If engine speed is too high the
transmission switches to a higher
gear, even in manual mode. Without
kickdown this automatic shift is not
effected in manual mode.
Fault
In the event of a fault, control indicator s is shown in the transmission
display.
Continued driving is possible,
provided the vehicle is driven with
care and anticipation. A warning
message may appear in the Driver
Information Centre in conjunction with
a warning chime 3 86.
Notice
The volume of the warning chime
can also be adjusted via the Driver
Information Centre 3 80.Have the cause of the fault remedied
by a workshop.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 the brake pedal
is depressed firmly. Considerably
more force is needed 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 75.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.
114Driving and operating
ABS starts to regulate brake pressureas 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.
After starting off the system performs
a self-test which may be audible.
Control indicator u 3 75.
Fault9 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 nolonger be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Parking brake Manual parking brake
Always apply parking brake firmly
without operating the release button,
and apply as firmly as possible on a
downhill or uphill slope.
To release the parking brake, pull the lever up slightly, press the release
button and fully lower the lever.
To reduce the operating forces of the
parking brake, depress the foot brake
at the same time.
A warning chime will sound if a certain speed is exceeded with the parking
brake applied.
Notice
The volume of the warning chime can also be adjusted via the Driver
Information Centre 3 80.
Control indicator R 3 75.
Brake assist
If the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the
brake pedal for as long as full braking is required. Maximum brake force is
automatically reduced when the
brake pedal is released.
