LED headlights
LED headlight system contains a
variety of particular LEDs in each
headlight which enables the control of different lighting programs.
Light distribution and intensity of light
are variably triggered depending on
the lighting conditions, road type and
driving situation. The vehicle adapts
the headlights automatically to the
situation to enable optimal light
performance for the driver.

Lighting139The following lighting functions are
available with light switch in position
AUTO or 9.
Town light
Activated automatically at a speed up to approx. 55 km/h and in situations
with exterior ambient light. The light is
wide and symmetrical. A special
beam pattern is designed to avoid
glare for other road users.
Country light
Activated automatically at a speed
above approx. 55 km/h when driving
in rural areas. The illumination of the
current lane and the side of the road is improved. Oncoming and
preceding vehicles are not dazzled.
Curve light
Particular LEDs, based on steering
angle and speed, are additionally
triggered to improve lighting in
curves. This function is activated at
speeds from 40 km/h to 70 km/h and
reacts to steering angle.
Corner light
When turning off, depending on the
steering angle and the turn signal light, particular LEDs are triggered
which illuminate the direction of
travel. It is activated up to a speed of
40 km/h.
Reverse parking function To assist driver's orientation when
parking, both corner lights and
reversing light illuminate when
headlights are on and reverse gear is
engaged. They remain illuminated for
a short time after disengaging reverse gear or until driving faster than
7 km/h in a forward gear.
High beam assist This feature allows the high beam to
function as main driving light at night.
The camera in the windscreen
detects the lights of oncoming or
preceding vehicles. Each LED on
right or left side can be triggered or
faded out particulary according to the
traffic situation. This gives the best
light distribution without glaring other
road users. Once activated, high
beam assist remains active and
switches high beam on and off
depending on surrounding

Battery discharge protection Vehicle battery state of charge
function
The function guarantees longest
vehicle battery life via a generator
with controllable power output and
optimised power distribution.To prevent discharge of the vehicle
battery when driving, the following
systems are reduced automatically in
two stages and finally switched off:
● auxiliary heater
● heated rear window and mirrors ● heated seats
● fan
In the second stage, a message
which confirms the activation of the
vehicle battery discharge protection
will be displayed in the Driver
Information Centre.

156Climate controlMaintenanceAir intake
The air intake in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.
Pollen filter The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
Air conditioning regular
operation
In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
month, irrespective of the weather
and time of year. Operation with
cooling is not possible when the
outside temperature is too low.
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
162Driving and operatingBefore restarting or to switch off the
engine when vehicle is stationary, press Engine Start/Stop once more
briefly.
Manual transmission: during an
Autostop, the engine can be started
by depressing the clutch pedal
3 163.
Automatic transmission or manual
transmission automated: during an
Autostop, the engine can be started
by releasing the brake pedal 3 163.
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 two seconds or press twice briefly within five seconds.9 Danger
Switching off the engine during
driving may cause loss of power
support for brake and steering
systems. Assistance systems and
airbag systems are disabled.
Lighting and brake lights will
extinguish. Therefore power down the engine and ignition while
driving only when required in case of 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.
five 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).
● Brake pedal not operated (manual transmission
automated).
● 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.
166Driving and operatingIf an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during the restart might be noticeable.
Note
If a trailer or a bike carrier is
attached, early Autostop and late
restart is deactivated.
Parking9 Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply the parking brake. Activate the manual
parking brake without pressing the release button. Apply as
firmly as possible on a downhill slope or uphill slope. Depress
brake pedal at the same time to
reduce operating force.
For vehicles with electric
parking brake, pull switch m for
a minimum of one second until
control indicator m illuminates
constantly and electric parking
brake is applied 3 111.
● Switch off the engine. ● If the vehicle is on a level surface or uphill slope, engage
first gear or set the selector
lever to position P before
removing the ignition key or
switching off ignition on
vehicles with power button. On
an uphill slope, turn the front
wheels away from the kerb.
If the vehicle is on a downhill
slope, engage reverse gear or
set the selector lever to position
P before removing the ignition
key or switching off ignition on
vehicles with power button.
Turn the front wheels towards
the kerb.
● Close the windows and the sunroof.
● Remove the ignition key from the ignition switch or switch off
ignition on vehicles with powerbutton. Turn the steering wheel until the steering wheel lock is
felt to engage.
For vehicles with automatic
transmission, the key can only
be removed when the selector
lever is in position P.
For vehicles with manual
transmission automated, the key can only be removed from
the ignition switch when the
parking brake is applied.
● Lock the vehicle.
● Activate the anti-theft alarm system.
● The engine cooling fans may run
after the engine has been
switched off 3 233.
Caution
After running at high engine
speeds or with high engine loads,
operate the engine briefly at a low load or run in neutral for
