Operation
Note
● If the c on
venience turn signals are operat-
ing (three flashes) and the other convenience
turn signals are switched on, the active part
stops flashing and only flashes once in the
new part selected.
● The turn signals only
work when the igni-
tion is switched on. The corresponding warn-
ing lamp or flashes in the instrument
panel. The control lamp flashes when the
turn signals are operated, provided a trailer is
correctly attached and connected to the vehi-
cle. If a turn signal bulb is defective, the con-
trol lamp flashes at double speed. If the trail-
er turn signal bulbs are defective, the control
lamp does not light up. Change the bulb.
● The main beam headligh
ts can only be
switched on if the dipped beam headlights
are already on. The warning lamp then
comes on in the instrument panel.
● The headlight flasher come
s on for as long
as you pull the lever – even if no other lights
are switched on. The warning lamp then
comes on in the instrument panel.
● When the parking ligh
ts are switched on,
the headlight and the tail light on the corre-
sponding side of the vehicle light up. The
parking lights will only work if the key is re-
moved from the ignition. If said light is on, an
audible warning will be emitted while the
driver door is open.
● If the turn signal lever is left on after the
key h
as been taken out of the ignition lock,
an acoustic signal sounds when the driver door is opened. This is intended as a remind-
er to sw
it
ch off the turn signal, unless you
wish to leave the parking light on. Coming Home/Leaving Home Func-
tion*
The Coming Home function is controlled man-
ually
.
The Leaving Home function is control-
led with a photosensor.
If the Coming Home or Leaving Home func-
tion is connected, the front side and dipped
lights, the tail lights and the number plate
light will light up to provide assistance.
Coming home function
The Coming Home function is activated by
switching off the ignition and briefly flashing
the lights. When the driver door is opened,
the Coming Home lighting comes on. If the
driver door is already open when the lights
are flashed briefly, the Coming Home lighting
comes on immediately.
When the last door of the vehicle or the rear
lid is closed, the Coming Home function
starts and the switching off the headlights is
delayed.
The Coming Home lighting switches off in the
following cases: ●
On comp l
etion of the time period establish-
ed for the delay in switching off the lights af-
ter all the vehicle doors and the rear lid have
been closed.
● If, 30 seconds after being connected, any
doors or the r
ear lid remain open.
● If the light switch is turned to position .
● If the ignition is switched on.
Automatic
Leaving Home function
The Leaving Home function is activated when
the vehicle is unlocked if:
● the light control is in position and
● the photo
sensor detects “darkness”.
The Leav
ing Home lighting switches off in the
following cases:
● If the time period for the delay in switching
off the hea
dlights has ended
● If the vehicle is locked again.
● If the light switch is turned to position .
● If the ignition is switched on.
Manual
Leaving Home function
In vehicles without an automatic headlight
system (light sensor), if the manual Coming
Home function is activated when leaving the
car, upon returning to the car and unlocking
it the manual Leaving Home function will be
activated automatically.

Mechanical steering lock
The steering column is locked when the key
is removed from the ignition lock and the ve-

Activating the steering lock
● Park the vehicle ›››

● Remove the ignition key.
● Turn the steering wheel slightly until the

Turn the steering wheel slightly to release

Electromechanical steering
In vehicles with electromechanical steering,
the assisted steering function automatically
adjusts according to vehicle speed, steering
wheel torque and wheel orientation. The
power steering only works when the engine
is running.
You should take into account that you will
need considerably more power than normal
to steer the vehicle if the power steering is
not working correctly or at all.
Power-assisted steering
Power-assisted steering helps the driver in
critical situations. In counter-steering, it as-
sists by applying additional torque ››› .
WARNING
Power-assisted steering, together with the
ESC, help s
the driver to control vehicle steer-
ing in critical situations. However, the driver
is ultimately responsible for steering the ve-
hicle at all times. Power-assisted steering
does not remove this responsibility. Starting and stopping the en-

Driver assistance systems
Electronic differential lock (XDS)* When taking a curve, the driveshaft differen-
tial
mec
hanism allows the outer wheel to turn
at a higher speed than the inner wheel. In
this way, the wheel that is turning faster (out-
er wheel) receives less drive torque than the
inner wheel. This may mean that in certain
situations the torque delivered to the inner
wheel is too high, causing the wheels to
spin. On the other hand, the outer wheel is
receiving a lower drive torque than it could
transmit. This causes an overall loss of lateral
grip on the front axle, resulting in understeer
or “lengthening” of the trajectory.
The XDS system can detect and correct this
effect via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the driver's
desired trajectory is much more precise.
The XDS system works in combination with
the ESC and is always active, even when ASR
traction control is disconnected or the ESC is
in Sport mode.
Brake servo The brake servo increases the pressure you
ap
p
ly
to the brake pedal. It works only when
the engine is running . If the brake servo is not functioning, e.g. due
to a malf
unction, or if the vehicle is being
towed, you will have to press the brake pedal
considerably harder to make up for the lack
of servo assistance. WARNING
The braking distance can also be affected by
ext ern
al factors.
● Never let the vehicle coast with the engine
switc
hed off. Failure to follow this instruction
could result in an accident. The braking dis-
tance is increased considerably when the
brake servo is not active.
● If the brake servo is not working, for exam-
ple when the
vehicle is being towed, you will
have to press the brake pedal considerably
harder than normal. Start-Stop System*

Vehicles with an automatic gearbox – Use the foot brake to bring the vehicle to a
stop and k
eep the brake pedal pressed
down with your foot. The engine will switch
off. The warning lamp will appear in the

Operatin
g and safety warnings WARNING
● The Re ar As
sist does not make it possible
to precisely calculate the distance from ob-
stacles (people, vehicles, etc.) and nor can it
overcome the system's own limits, hence us-
ing it may cause serious accidents and inju-
ries if used negligently or without due care.
The driver should be aware of his/her sur-
roundings at all times to ensure safe driving.
● The camera lens expands and distorts the
field of
vision and displays the objects on the
screen in a different, vague manner. The per-
ception of distances is also distorted by this
effect.
● Some objects may, due to the resolution of
the disp
lay screen - not be displayed in a sat-
isfactory manner or may not be displayed at
all. Take special care with thin posts, fences,
railings or trees that might not be displayed
on screen and could damage the vehicle.
● The rear assist has blind spots where it is
not pos
sible to represent people or objects
(small children, animals and certain objects cannot be detected in its field of vision). Mon-
itor the
v
ehicle's surrounding area at all
times.
● Keep the camera lens clean, free of ice and
snow
, and do not cover it.
● The system is not a replacement for driver
awar
eness. Supervise the parking operation
at all times, as well as the vehicle's surround-
ing area. Adapt your speed and driving style
at all times to suit visibility, weather, road
and traffic conditions.
● Do not be distracted from the traffic by
looking at
the screen.
● The images on the rear assist screen are
only tw
o-dimensional. Due to a lack of spatial
depth, protruding parts or holes in the road,
for example, are more difficult to detect or
may not be seen at all.
● Vehicle load modifies the representation of
the orientation lines
displayed. The width
represented by the lines diminishes with ve-
hicle load. Pay special attention to the vehi-
cle's surroundings when the inside of the ve-
hicle of the luggage compartment is carrying
a heavy load.
● In the following situations, the objects or
other vehic
les shown in the navigation sys-
tem display appear to be further away or
closer than they really are: Pay special atten-
tion:
– On moving from a horizontal plane to a
slope.
