142Driving and operatingEmergency operation under
extreme cold temperatures9 Warning
This emergency operation may
only be carried out in case of
extremely cold temperatures and if the vehicle is parked on a levelsurface.
In countries with extreme cold
temperatures it may be necessary to
park the vehicle without applied
parking brake.
This is an emergency operation to
avoid freezing of the parking brake.
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
Automatic cleaning process
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases.
The start of saturation of the particle
filter is indicated by the temporary illumination of % or H ,
accompanied by a message in the
Driver Information Centre.
As soon as the traffic conditions
permit, regenerate the filter by driving at a vehicle speed of at least 40 mph
until the control indicator
extinguishes.
Notice
On a new vehicle, the first particle
filter regeneration operations may
be accompanied by a burning smell,
which is normal. Following
prolonged operation of the vehicle at very low speed or at idle, you may,
in exceptional circumstances, notice
the emission of water vapour at the
exhaust on acceleration. This does
not affect the behaviour of the
vehicle or the environment.
Cleaning process not possible
If % or H stays on, accompanied
by an audible signal and a message,
this indicates that the particle filter
additive level is too low.
The reservoir must be topped-up
without delay. Seek the assistance of
a workshop.

The automatic transmission permits
automatic gearshifting (automatic
mode) or manual gearshifting
(manual mode).
Manual shifting is possible in manual
mode by tapping the selector lever to + or - 3 148.
Transmission display
The mode or selected gear is shown
in the Driver Information Centre.
In automatic mode, the driving
programme is indicated by D.

towards the left in position M.
Tap selector lever upwards + to shift
to a higher gear.
Tap the selector lever downwards - to
shift to a lower gear.
If a higher gear is selected when
vehicle speed is too low, or a lower
gear when vehicle speed is too high,
the shift is not executed. This can
cause a message in the Driver
Information Centre.
In manual mode, no automatic
shifting to a higher gear takes place
at high engine revolutions.
Gear shift indication
The symbol R or S with a number
beside it is indicated when
gearshifting is recommended for fuel
saving reasons.
Shift indication appears only in
manual mode.
Electronic driving programmes
● Following a cold start, the operating temperature
programme increases engine
speed to quickly bring the
catalytic converter to the required
temperature.
● Special programmes automatically adapt the shifting
points when driving up inclines or
down hills.
● In snowy or icy conditions or on other slippery surfaces, the
electronic transmission controlenables the driver to select
manually first, second or third
gear for starting off.
Kickdown Pressing down the accelerator pedal
beyond the kickdown detent will lead
to maximum acceleration
independent of selected driving
mode. The transmission shifts to a
lower gear depending on engine
speed.
Fault
In the event of a fault a message is
displayed in the Driver Information
Centre. Vehicle messages 3 103.
Electronic transmission control
enables only third gear. The
transmission no longer shifts
automatically.
Do not drive faster than 62 mph.
Have the cause of the fault remedied by a workshop.
150Driving and operatingWhen clutch slip is detected for a
specific time, the engine power will be
reduced. A warning is displayed in the Driver Information Centre. Release
the clutch.Caution
It is not advisable to drive with the hand resting on the selector lever.
Gear shift indication 3 96.
Stop-start system 3 139.
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 the 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 m 3 95.
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.
After starting off, the system performs
a self-test which may be audible.
Control indicator u 3 95.
Adaptive brake light
During full braking, all three brake
lights flash for the duration of ABS
control.
152Driving and operatingDynamic braking when vehicle is
moving
When the vehicle is moving and the
switch m is kept pulled, the electric
parking brake system will decelerate the vehicle, but will not apply
statically.
As soon as the switch m is released,
dynamic braking will be stopped.
Automatic operation
Automatic operation includes
automatic application and automatic
release of the electric parking brake.
The electric parking brake can also be
applied or released manually by using
the switch m.
Automatic application: ● The electric parking brake is automatically applied when the
vehicle is stationary and the
ignition is switched off.
● j illuminates in the instrument
cluster and a display message
pops up to confirm the
application.Automatic release:
● Parking brake releases automatically after moving off.
● j extinguishes in the instrument
cluster and a display message
pops up to confirm the release.
If the vehicle is equipped with an
automatic transmission and the brake
