Climate control151
Active carbon filterIn addition to the particle filter, theactive carbon filter reduces odours.
Filter replacement must be carried out
during a regular service.
Air conditioning regular
operation In order to ensure continuously
efficient performance, it is
recommended that air conditioning
should be operated for a few minutes once a month, irrespective of the
weather and time of year.
Service
For optimal cooling performance, it is recommended to annually check the
climate control system, starting
three years after initial vehicle
registration, including:
■ functionality and pressure test
■ heating functionality
■ leakage check
■ check of drive belts■ cleaning of condenser and evaporator drainage
■ performance check
156Driving and operating
Do not operate accelerator pedal.
Press and release Engine Start/Stop:
an automatic procedure operates the
starter with a short delay until the
engine is running, see Automatic
Starter Control.
Before restarting or to switch off the engine when vehicle is stationary, press Engine Start/Stop once more
briefly.
During an Autostop, the engine can
be started by depressing the clutch
pedal 3 157.
Emergency shut off during
driving If the engine needs to be switched offduring driving in case of emergency,
press Engine Start/Stop for longer
than 2 seconds or press twice briefly
within 5 seconds.9 Danger
Switching off the vehicle engine
during driving may cause loss of
power support of brake and
steering systems. Assistance
systems and airbag systems are
disabled. Lighting and brake lights will extinguish. Therefore powerdown the engine and ignition while
driving only in case of vehicle
emergency.
Starting the vehicle at low
temperatures
Starting the engine without additional heaters is possible down to -25 °С for
diesel engines and -30 °C for petrol
engines. Required is an engine oil
with the correct viscosity, the correct
fuel, performed services and a
sufficiently charged vehicle battery.
With temperatures below -30 °C the
automatic transmission requires a
warming phase of approx. 5 minutes.
The selector lever must be in position
P .
Automatic Starter Control
This function controls the engine
starting procedure. The driver does
not need to hold the key in position 3
or to hold Engine Start/Stop pressed.
Once applied, the system will go on
starting automatically until the engine
is running. Because of the checking
procedure, the engine starts running
after a short delay.
Possible reasons for a non-starting
engine:
■ Clutch pedal not operated (manual transmission).
■ Brake pedal not operated or selector lever not in P or N
(automatic transmission).
■ Timeout occurred.
Turbo engine warm-up Upon start-up, engine available
torque may be limited for a short time, especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully
protect the engine.
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 pedal is released.
Driving and operating169Caution
It is not advisable to drive with thehand resting on the selector lever.

Drive systems
All-wheel drive
The All-wheel drive system enhances
driving characteristics and stability,
and helps to achieve the best
possible driveability regardless of
ground surface. The system is always active and cannot be deactivated.
The torque is distributed steplessly
between the wheels of the front and rear axle, depending on the driving
conditions. Additionally the torque
between the rear wheels is distributed
depending on the surface.
For optimum system performance,
the vehicle's tyres should not have
varying degrees of wear.
If a service message is displayed in
the Driver Information Centre, the
system may have limited functionality
(or be completely disabled in some
cases, i.e. the vehicle switches to
Front-wheel drive). Seek the
assistance of a workshop.
Towing the vehicle 3 264.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 3 106.
Antilock brake system Antilock brake system (ABS)
prevents the wheels from locking.
192Driving and operating
Emergency automatic brakingAfter the brake preparation and just
before the imminent collision, this
function automatically applies limited
braking to reduce the impact speed of the collision.
Below a speed of 11 mph the system
can apply full braking.
Forward looking brake assist
In addition to the brake preparation
system and emergency automatic
braking, the forward looking brake
assist function makes the brake assist more sensitive. Therefore,
depressing the brake pedal less
strongly results in immediate hard
braking. This function helps the driver brake quicker and harder before the
imminent collision.9 Warning
Active emergency braking is not
designed to apply hard
autonomous braking or to
automatically avoid a collision. It is designed to reduce the vehicle
speed before a collision. It may not
react for stopped vehicles,
pedestrians or animals. After a
sudden lane change, the system
needs a certain time to detect the
next preceding vehicle.
The complete attention of the
driver is always required while
driving. The driver shall always be ready to take action and apply the
brakes and steer to avoid
collisions. The system is designed to work with all occupants wearingtheir seat belts.
System limitations
The active emergency braking has
limited or no function during rain,
snow or heavy dirt, as the radar
sensor can be covered by a water
film, dust, ice or snow. In case of
sensor blockage, clean the sensor
cover.
In some cases, the active emergency braking system may provide an
automatic braking in situations that
seem to be unnecessary, for instance
in parking garages, due to traffic signs
in a curve or due to vehicles in
another lane. This is normal
operation, the vehicle does not need
service. Firmly apply the accelerator
pedal to override the automatic
braking.

Notice
After production, the system
requires a calibration. For optimal performance, drive as soon as
possible on a straight highway road
with roadside objects, e.g. guardrails
and barriers for some distance.
Fault
Occasional missed alerts can occur
under normal circumstances or in
sharp curves. Otherwise the system may light up due to guardrails, signs,trees, shrubs or other immobile
objects. This is normal operation and
the system does not need to be
serviced.
Lane change alert may not operate
when the left or right corners of the
rear bumper are covered with mud,
dirt, snow, ice or slush. Cleaning
instructions 3 267.
In the event of a fault in the system or if the system does not work due to
temporary conditions, a message is
displayed in the DIC. Seek the
assistance of a workshop.
Rear view camera The rear view camera assists the
driver when reversing, by displaying a view of the area behind the vehicle.
The view of the camera is displayed
in the Colour-Info-Display.9 Warning
The rear view camera does not
replace driver vision. Note that
objects that are outside the
camera's field of view and the
advanced parking assist sensors,
e.g. below the bumper or
underneath the vehicle, are not
displayed.
Do not reverse the vehicle by only looking at the Info-Display and
check the surrounding area
behind and around the vehicle
before reversing.
Activation
Rear view camera is automatically
activated when reverse gear is
engaged.
