Driving and operating163Limited-slip rear axle
Rear-wheel drive vehicles may be
equipped with an automatic locking
rear differential which automatically
controls the torque transmitted to
each rear wheel, enhancing traction
in the event of soft ground, mud or
snow-covered road surfaces.9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
When vehicle speed reaches
30 km/h, or once the rear wheels
return to surfaces with normal grip,
e.g. paved roads, the system
automatically deactivates,
sometimes accompanied by a noise
(with no consequence to vehicle
behaviour).
The system can also be deactivated
manually once normal grip conditions have resumed by briefly releasing the
accelerator.
Driver assistance
systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation.
Cruise control
The cruise control can store and
maintain speeds of 30 km/h and
above. Deviations from the stored
speeds may occur when driving uphill or downhill. The stored speed will
flash in the Driver Information Centre
3 106.
For safety reasons the cruise control
cannot be activated until the brake
pedal has been operated once.
Do not use the cruise control if it is not advisable to maintain a constant
speed.
With manual transmission
automated, only activate cruise
control in automatic mode.
Control indicators m and U 3 105.
Switching on the system
Press m, control indicator U
illuminates green in the instrument
cluster.
164Driving and operatingCruise control is now in standby mode
and a corresponding message
appears in the Driver Information
Centre.
Accelerate to the desired speed and
press < or ]. The current speed is
now stored and maintained and the
accelerator pedal can be released.
Control indicator m illuminates green
in the instrument cluster together with
U and a corresponding message
appears in the Driver Information
Centre.
Vehicle speed can be increased by
depressing the accelerator pedal.
The stored speed flashes in the
instrument cluster. When the
accelerator pedal is released, the
previously stored speed is resumed.
Cruise control remains activated
while gearshifting.
The speed is saved until the ignition
is switched off.
Increase speed
With cruise control active, the vehicle speed can be increased continuously
or in small increments by holding
down or tapping < repeatedly.
When the switch is released the
current speed is stored and
maintained.
Alternatively, accelerate to the
desired speed and store by pressing
< .
Reduce speed
With cruise control active, the vehicle speed can be decreased
continuously or in small increments
by holding down or tapping ]
repeatedly.
When the switch is released the
current speed is stored and
maintained.
Driving and operating165Deactivation of the functionality
Press $: cruise control is deactivated
and the green control indicator m
extinguishes in the instrument cluster.
Automatic deactivation: ● vehicle speed drops below 30 km/h
● the brake pedal is depressed
● the clutch pedal is depressed
● selector lever in N
The speed is stored and a
corresponding message appears in
the Driver Information Centre.
Activation of the functionality
Press R at a speed above 30 km/h.
If the stored speed is much higher
than the current speed, the vehicle
will accelerate powerfully until the
stored speed is obtained.
Pressing < will also reactivate the
cruise control function, but at the
current vehicle speed only, not the stored speed.
Switching off the system
Press m, green control indicators U
and m extinguish in the instrument
cluster.
Speed limiter
The speed limiter prevents the
vehicle exceeding a preset maximum
speed above 30 km/h.Switching on the system
Press U, control indicator U
illuminates yellow in the instrument
cluster.
Speed limiter function is now in
standby mode and a corresponding
message appears in the Driver
Information Centre.
Driving and operating167Switching off the system
Press U.
Yellow control indicator U
extinguishes in the instrument cluster.
Maximum speed limiterIn accordance with local or national
regulations, the vehicle may be
equipped with a fixed maximum
speed limiter that cannot be disabled.
If equipped, a warning label indicating the fixed maximum speed limit (90 to
130 km/h) is located on the
instrument panel.
Deviations from the maximum speed
limit may occur briefly when driving
downhill, for physical reasons.
A warning chime may sound for
10 seconds if the vehicle briefly
exceeds the set limit.
Vehicles also equipped with speed
limiter: the maximum speed cannot
be exceeded by depressing the
accelerator pedal firmly beyond the
point of resistance.Active emergency braking
Active emergency braking can help to reduce the damage and injury from
crashes with vehicles directly ahead,
when a collision can no longer be
avoided either by manual braking or
by steering. The feature uses various
inputs (e.g. camera sensor, radar
sensor, brake pressure, vehicle
speed) to calculate the probability of a frontal collision.9 Warning
This system is not intended to
replace the driver responsibility for driving the vehicle and looking
ahead. Its function is limited to
supplemental use only to reduce
the vehicle speed before a
collision.
The system only detects vehicles
driving in the same direction of
traffic.
After a sudden lane change, the
system needs a certain time to
detect the next preceding vehicle.
The driver must always be ready
to take action and apply the brakes and steer to avoid collisions.
Operation conditions
The system is operational at a vehicle
speed between 15 km/h and
100 km/h.
Activation The system is automatically activewhen the ignition is switched on.
Functionality
When driving in the speed range
mentioned above and a risk of
collision with the vehicle ahead is
imminent, l will flash and a warning
chime sounds.
The indicator light l and the chimes
stop when the system detects that a
collision is not imminent anymore.
Just before the imminent collision, the system brakes automatically to
reduce the impact speed of the
collision or prohibit a crash.
168Driving and operating9Warning
Do not rely on the system to brake
the vehicle. Active emergency
braking will not brake outside of its
operating speed range and only
responds to detected vehicles.
Deactivation and re-activation
Active emergency braking can be
deactivated with the vehicle
stationary and the ignition switched
on:
Toggle through the Driver Information Centre with the buttons on the right
stalk tip until message AEBS
ACTIVE appears.
To deactivate the system, press and
hold one of the two buttons for
approx. 3 seconds. Message AEBS
DEACTIVATED is displayed and l
illuminates in the instrument cluster until system is re-activated again.
To re-activate the system, press and hold one of the two buttons for
approx. 3 seconds. Message AEBS
ACTIVE is displayed and l
disappears.
Vehicle messages 3 107.
We recommend to deactivate the
system in the vehicle personalisation
in the following cases:
● when the vehicle is being towed
● before using an automatic car wash with ignition switched on
● if the windscreen has been damaged close to the camera
● if the front bumper has been damagedConditions for re-activation
The Active emergency brake system can only be re-activated if:
● the gear lever is not in neutral
● parking brake is not activated
● vehicle is not cornering
System limitations In some cases, the active emergencybraking 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 if the situation and the
surroundings permit.
In the following cases, active
emergency braking performance is
limited:
● driving on winding or hilly roads
● detecting all vehicles, especially vehicles with a trailer, tractors,
muddy vehicles, etc.
Driving and operating173● the rear doors are not closedcorrectly
● the vehicle had a rear-end accident
● there are extreme temperature changes
Lane departure warning The lane departure warning system
uses a front camera to observe the
lane markings between which the
vehicle is driving. The system detects
lane changes and warns the driver in
the event of an unintended lane
change via visual and acoustic
signals.
Criteria for the detection of an
unintended lane change are:
● no operation of turn lights
● no active steering
If the driver is performing these
actions, no warning will be issued.Activation
The lane departure warning system is activated by pressing ì in the roof
console. The LED in the button
extinguishes to indicate that the
system is switched on.
When control indicator ì 3 103
illuminates in the instrument cluster,
the system is ready to operate. A
corresponding message also
appears in the Driver Information
Centre 3 106.
Control indicator ì extinguishes
when the system is not ready to warn the driver.
The system is only operable at
vehicle speeds above 60 km/h and if
lane markings are available and
detected.
If the turn lights are not operated
when changing lanes, i.e. an
unintended lane change is detected,
224Vehicle careFor mechanical removal of ice, use a
sharp-edged ice scraper. Press the
scraper firmly against the glass so
that no dirt can get under it and
scratch the glass.
Remove dirt residues from smearing
wiper blades by using a soft cloth and window cleaner. Also make sure to
remove any residues such as wax,
insect residues and similar from the
window.
Wheels and tyres Do not use high-pressure jet
cleaners.
Clean rims with a pH-neutral wheel
cleaner.
Rims are painted and can be treated
with the same agents as the body.
Paintwork damage
Rectify minor paintwork damage with a touch-up pen before rust forms.
Have more extensive damage or rust areas repaired by a workshop.Underbody
Some areas of the vehicle underbody
have a PVC undercoating while other
critical areas have a durable
protective wax coating.
After the underbody is washed, check
the underbody and have it waxed if
necessary.
Bitumen / rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.
Before and after winter, wash the
underbody and have the protective
wax coating checked.
Towing equipment
Do not clean the coupling ball bar with a steam-jet or high-pressure jet
cleaner.Interior care
Interior and upholstery Only clean the vehicle interior,
including the instrument panel fascia
and panelling, with a dry cloth or
interior cleaner.
Clean leather upholstery with clear
water and a soft cloth. In case of
heavy soiling, use leather care.
The instrument cluster and the
displays should only be cleaned using
a soft damp cloth. If necessary use a
weak soap solution.
Clean fabric upholstery with a
vacuum cleaner and brush. Remove
stains with an upholstery cleaner.
Clothing fabrics may not be
colourfast. This could cause visible
discolourations, especially on light-
coloured upholstery. Removable
stains and discolourations should be
cleaned as soon as possible.
Clean seat belts with lukewarm water or interior cleaner.
