deactivate high beam assist.
Pushing the indicator lever to activate manual high beam will also
deactivate high beam assist.Headlight flash in conjunction with
high beam assist
Headlight flash by pulling indicator
lever once will not deactivate high beam assist when high beam is off.
Headlight flash by pulling indicator
lever once deactivates high beam
assist when high beam is on.
142LightingActivate temporary flashing by
holding the lever just before the
resistance point. Turning lights will
flash until lever is being released.
To activate three flashes, tap the
lever briefly without passing the
resistance point. With a trailer
connected, the turn signal flashes
six times and tone frequency
changes.
Front fog lights
Operated by pressing >.
Light switch in position AUTO:
switching on front fog lights will switch headlights on automatically.
Rear fog light
Operated by pressing ø.
Light switch in position AUTO:
switching on rear fog light will switch
headlights on automatically.
Light switch in position 8: rear fog
light can only be switched on with
front fog lights.
The vehicle rear fog light is
deactivated when towing a trailer or a
plug is connected with the socket, e.
g. when a bicycle carrier is used.
Parking lights
When the vehicle is parked, the
parking lights on one side can be
activated:
1. Switch off ignition.
2. Move turn signal lever all the way up (right parking lights) or down
(left parking lights).
Confirmed by a signal and the
corresponding turn signal control
indicator.
178Driving and operatingDrive 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 up to a torque split of 50%
to 50%. Depending on the driving
conditions, i.e. steady state driving,
All wheel drive system transfers a
minimum amount of torque for fuel
efficiency. Additionally the torque
vectoring between the rear wheels is
distributed depending on the vehicle
dynamic and surface.
This is possible because the All wheel drive system operates with two
clutches, one on each side.
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 3 277.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 R 3 107.
Active emergency braking 3 201.
Antilock brake system Antilock brake system (ABS)
prevents the wheels from locking.
Driving and operating217Detection zones
The system sensors cover a zone of
approx. 3.5 metres parallel on both
vehicle sides and approx. 3 metres
rearwards on side blind zone alert
(A) and approx. 50 metres rearwards
on lane change alert (B) on parallel
lanes. The zones start at each
exterior mirror. The height of the zone
is approx. between 0.5 metres and
2 metres off the ground.
Deactivation
Activation or deactivation of the lane
change alert can be set in the vehicle personalisation menu in the Info-
Display.
Vehicle personalisation 3 125.
Info-Display 3 119.
The system is deactivated if the
vehicle is towing a trailer.
Deactivation is indicated by a
message in the Driver Information
Centre.
System limitations Occasional missed alerts can occur
under normal circumstances or in
sharp curves. The system can
temporarily alert of objects in the blind spot at specific weather conditions(rain, hail etc). Driving on a wet road
or in the transitions from a dry area to
a wet area can cause the control
indicator F to light up, as water
splash can be interpreted as an
object. Otherwise the control indicator F may illuminate due to guardrails,
signs, trees, shrubs or other immobile
objects. This is normal operation and
the system does not need to be
serviced.The system may not operate properly
when:
● Ice, snow, mud, stickers, magnets, metal plates, or
anything else covers the sensors.
● Driving in heavy rainstorms.
● The vehicle had an accident or if the area surrounding the
detection sensor is damaged or
not properly repaired.
● There are extreme temperature changes.
● The vehicle is towing a trailer
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 Driver Information
Centre. Seek the assistance of a
workshop.
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.

266Vehicle careThe legally permissible minimumtread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap round front wheels and rear wheels periodically. Ensure that
the direction of rotation of the wheels
remains the same.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
Changing tyre and wheel size
If tyres of a different size than those
fitted at the factory are used, it may be necessary to reprogramme the
speedometer as well as the nominal
tyre pressure and make other vehicle
modifications.After converting to a different tyre
size, have the label with tyre
pressures replaced and the tyre
deflation detection system
reinitialised. 3 2639 Warning
The use of unsuitable tyres or
wheels may lead to accidents and will invalidate the vehicle
operating permit.
Wheel covers
Wheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination
requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
not have a rim protection ridge.
Wheel covers must not impair brake
cooling.
9 Warning
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
Vehicles with steel wheels: When
using locking wheel nuts, do not
attach wheel covers.
Tyre chains
Tyre chains are only permitted on the
front wheels.
