160Driving and operatingDectivation
The system can be deactivated.
Press V repeatedly until Forward
Collision Alert Off appears in the
Driver Information Centre.
General information9 Warning
Forward collision alert is just a
warning system and does not
apply the brakes. When
approaching a vehicle ahead too
rapidly, it may not provide you
enough time to avoid a collision.
The driver accepts full
responsibility for the appropriate
following distance based on traffic, weather and visibility conditions.
The complete attention of the
driver is always required while
driving. The driver must always be
ready to take action and apply the
brakes.
System limitations
Forward collision alert is designed to warn on vehicles only, but may reactalso to other objects.
In the following cases, forward
collision alert may not detect a vehicle ahead or sensor performance is
limited:
● on winding roads
● when weather limits visibility, such as fog, rain, or snow
● when the sensor is blocked by snow, ice, slush, mud, dirt,
windscreen damage or affected
by foreign items, e.g. stickers
Following distance indication
The following distance indication
displays the distance to a preceding
moving vehicle. The system uses the
front camera in the windscreen to
detect the distance of a vehicle
directly ahead in your path. It is active
at speeds above 40 km/h.When a preceding vehicle is detected
ahead, the distance is indicated in
seconds, displayed on a page in the
Driver Information Centre 3 96 . Press
MENU on the turn signal lever to
select Vehicle Information
Menu ? and turn the adjuster
wheel to choose following distance
indication page.
The minimum indicated distance is
0.5 s.
If there is no vehicle ahead or the vehicle ahead is out of range, two
dashes will be displayed: -.- s.

Driving and operating161Parking assist
The parking assist makes parking
easier by measuring the distance between the vehicle and obstacles,
and giving acoustic signals. It is the
driver, however, who bears full
responsibility for the parking
manoeuvre.
The system consists of four ultrasonic parking sensors in the rear bumper. If
the vehicle is equipped with a front
parking assist the system consists of
four additional ultrasonic parking
sensors in the front bumper.
Activation
After ignition is switched on, the rear
parking assist is activated.
The front parking assist can also be activated at a low speed by pressing
r .
An illuminated LED in the parking
assist button indicates that the
system is ready to operate.
An obstacle is indicated by a buzzing
sound. The interval between the sounds becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm, the buzzing is continuous.
If r is pressed once within an
ignition cycle, the front parking assist
is reactivated if the vehicle speed
goes below a certain value and if the
vehicle speed has not exceeded
25 km/h beforehand.
Deactivation
Deactivate the system by pressing
r .
The LED in the button will go out and
Park Assist Off will be displayed in the
Driver Information Centre.
If the parking assist is deactivated
manually, it will be reactivated
automatically the next time the
ignition is switched on.
The system is deactivated
automatically at a certain speed.
Fault
In the event of a fault in the system, a
vehicle message is displayed in the Driver Information Centre.
Additionally, a vehicle message is
displayed in the Driver Information
Centre if a malfunction of the system
due to temporary conditions, e.g.
snow covered sensors is detected.

168Driving and operatingCaution
The system is intended to help thedriver within a defined speed
range to discern certain traffic
signs. Do not ignore traffic signs
which are not displayed by the
system.
The system does not discern any other than the conventional traffic
signs that might give or end a
speed limit.
Do not let this special feature
tempt you into taking risks when
driving.
Always adapt speed to the road
conditions.
The driver assistance systems do not relieve the driver from full
responsibility for vehicle
operation.
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
● no active steering
If the driver is active, no warning will
be issued.
ActivationThe lane departure warning system isactivated by pressing ). The
illuminated LED in the button
indicates that the system is switched
on.
When the control indicator ) in the
instrument cluster illuminates green,
the system is ready to operate.
The system is only operable at
vehicle speeds above 56 km/h and if
lane markings are available.
When the system recognises an
unintended lane change, the control
indicator ) changes to yellow and
flashes. Simultaneously a chime
sound is activated.

Driving and operating177The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 225.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
The maximum permissible vertical
coupling load (75 kg) is specified on
the towing equipment identification
plate and in the vehicle documents.
Always aim for the maximum load,
especially in the case of heavy
trailers. The vertical coupling load
should never fall below 25 kg.
Rear axle load
The permissible axle loads (see
identification plate or vehicle
documents) must not be exceeded.Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.
Stowage of coupling ball bar
The bag with the coupling ball bar is
stowed in the rear stowage
compartment on the floor.
Place the strap through the lashing
eye, wrap around twice and tighten
the strap to secure the bag.
Fitting the coupling ball bar
Disengage and fold down the socket. Remove the sealing plug from the
opening for the coupling ball bar and
stow it.

Fuses
Data on the replacement fuse must
match the data on the defective fuse.
In a box above the positive terminal of
the battery are some main fuses. If
necessary have them changed by a workshop.
Before replacing a fuse, turn off the
respective switch and the ignition.
A blown fuse can be recognised by its melted wire. Do not replace the fuse
until the cause of the fault has been
remedied.
Some functions are protected by
several fuses.
Fuses may also be inserted without existence of a function.
Note
Not all fuse box descriptions in this
manual may apply to your vehicle.
When inspecting the fuse box, refer
to the fuse box label.

200Vehicle caretread life. After changing to winter
tyres, be alert for changes in vehicle
handling and braking.
If using winter tyres, make sure to use ● tyres of the same brand and tread
type on all four wheel positions.
● only radial ply tyres of the same size, load range and speed ratingas the tyres originally fitted at the factory.
Winter tyres with the same speed
rating as the tyres originally fitted at
the factory may not be available for H,
V, W, Y and ZR speed rated tyres. If using winter tyres with a lower speed
rating, never exceed the tyre's
maximum speed capability.

Directional tyres
Fit directional tyres such that they roll in the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring system.
Tyre pressure 3 236.
The tyre pressure information label
on the left or right door frame
indicates the original equipment tyres
and the correspondent tyre
pressures.
For countries outside the European
Union, the tyre pressure is
independent of the tyre load.
