Turn and lane-change signalslever up:right turn signallever down:left turn signal
A resistance point can be felt bymoving the lever.
Move the lever past the resistance
point to switch on constantly. When
the steering wheel moves opposite,
the turn signal is automatically
deactivated. Switch off manually by
moving the lever to its original
position.
Tap shortly to switch on for three
flashes, e.g., when changing lanes.
Move the lever to the resistance point
and hold for flashing until lever is
released.
If you forget to cancel the turn and
lane-change signals for more than
twenty seconds, the volume of the
audible signal will increase if the
speed is above 60 km/h.Front fog lights

Driving and operating157When the time to a potential collision
with a vehicle in front gets too small
and a collision is imminent, a warning
is displayed in the Driver Information
Centre.
Simultaneously a warning chime
sounds. Depress the brake pedal and
steer the vehicle, if it is required by the
situation.
Operation conditions The following condition must be
fullfilled for proper operation:
The speed must be between 5 km/h
and 140 km/h.
Activation To use forward colision alert, active
safety braking has to be activated in
the vehicle personalisation 3 103.
Selecting the alert sensitivity
The alert sensitivity has to be set to
close, normal or distant in the vehicle
personalisation menu 3 103.Deactivation
The system can only be deactivated
by deactivating the active emergency
braking in the vehicle personalisation
3 103.
System limitations Forward collision alert is designed to
warn on vehicles only, but may react also to other objects.
In the following cases, forward
collision alert may not detect a vehicle
ahead or sensor performance is
limited:
● Driving on winding or hilly roads.
● During nighttime driving.
● Weather limits visibility, such as fog, rain, or snow
● The windscreen is damaged or affected by foreign items, e.g.
stickers.
Active emergency braking
Active emergency braking can help to reduce the damage and injury from
crashes with vehicles, pedestrians
and obstacles directly ahead, when acollision can no longer be avoided
either by manual braking or by
steering. Before the active
emergency braking applies, the driver
is warned by the forward collision
alert 3 156 or the front pedestrian
protection alert 3 159.
The feature uses various inputs (e.g. camera 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 may not react to
animals. 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.

Deactivation Active emergency braking can be
deactivated in the vehicle
personalisation menu 3 103. If
deactivated a message is displayed in the Driver Information Centre.
System limitations
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 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.
● Detecting a vehicle when weather limits visibility, such as in
fog, rain, or snow.
● During nighttime driving.● Weather limits visibility, such as fog, rain, or snow.
● The windscreen is damaged or affected by foreign items, e.g.
stickers.
Complete attention is always required while driving, and you should be
ready to take action and apply the
brakes and/or steer the vehicle to
avoid crashes.
Fault
In case the system requires a service, a message is displayed in the Driver
Information Centre.
If the system does not work as it
should do, vehicle messages are
displayed in the Driver Information
Centre.

Caution
For optimal operation of the
system, it is important to keep the
lense of the camera in the tailgate between the number plate lightsalways clean. Rinse the lense with water and wipe with a soft cloth.
Do not clean the lense with a
steam-jet or high-pressure jet
cleaner.

Lane departure warning
The lane departure warning system
observes the lane markings between
which the vehicle is driving via a front camera. 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 signals.
● No brake pedal operation.
● No active accelerator operation or speeding-up.
Driving and operating175If the driver is active, no warning will
be issued.
Activation
The lane departure warning system is activated by pressing ½. The system
is switched on when the LED in the
button is not illuminated.
The system is only operable at
vehicle speeds above 60 km/h and if
lane markings are available.
When the system recognises an
unintended lane change, the control
indicator ) flashes yellow.
Simultaneously a chime sound is
activated.
Deactivation

pressing ½, the LED in the button
illuminates.
At speeds below 60 km/h the system
is inoperable.
Fault
In the event of a fault, F

workshop to have the system
checked.
The lane departure warning system
may not operate properly when:

● There are adverse environmental
conditions like heavy rain, snow,
direct sunlight or shadows.
The system can not operate when no
lane marking is detected.
System limitations The system performance may not
operate properly when:

Driving and operating181Trailer hitch
General information
The factory-fitted towing equipment is
folded up under the rear bumper
fascia.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment. Only use
towing equipment that has been
approved for your vehicle.
To avoid vehicle damage, the power
tailgate cannot be operated with the
radio remote control when a trailer is
electrically connected.
The bulb outage detection function for trailer brake light cannot detect a
partial bulb outage, e.g. in case of four
times five watt bulbs, the function only detects lamp outage when only a
single five Watt lamp remains or none remain.
Fitting of towing equipment could
cover the opening of the towing eye.
If this is the case use the coupling ball
bar for towing.Driving characteristics and
towing tips
Before attaching a trailer, lubricate the coupling ball. However, do not do so if a stabiliser, which acts on thecoupling ball, is being used to reduce
snaking movements.
During trailer towing do not exceed a
speed of 80 km/h. A maximum speed
of 100 km/h is only appropriate if an
oscillation damper is used and the
permissible gross trailer weight does
not exceed the vehicle’s curb weight.
For trailers with low driving stability
and caravan trailers, the use of an
oscillation damper is strongly
recommended.
If the trailer starts snaking, drive more slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 239.Trailer towing
Trailer loads The permissible trailer loads are
vehicle and engine-dependent
maximum values which must not be
exceeded. The actual trailer load is the difference between the actual
gross weight of the trailer and the
actual coupling socket load with the
trailer coupled.
The permissible trailer loads are
specified in the vehicle documents. In general, they are valid for gradients
up to 12%.
The permissible trailer load applies
up to the specified incline and at sea
level. Since engine power decreases
as altitude increases due to the air
becoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10%
for every 1000 metres of altitude. The gross train weight does not have to be reduced when driving on roads with
slight inclines (less than 8%, e.g.
motorways).
