Rear doors
Important safety notes
GWARNING
If you open a rear door, you could:
Rendanger other people or road users
Rbe caught by oncoming traffic
This is particularly the case if you open the
rear door more than 90°. There is a risk of an
accident and injury.
Only open the rear doors when traffic condi-
tions permit. Always make sure that the rear
doors are properly locked.
GWARNING
If you open the rear doors 90°, the rear lights are no longer visible. The vehicle will then be
difficult for other road users to see or will not
be seen by them at all, particularly if it is dark
or visibility is poor. There is a risk of an acci-
dent.
You should therefore ensure in this and simi-
lar situations that the vehicle is visible from
the rear in accordance with the relevant
national regulations, by using the warning tri-
angle, for instance.
!Make sure that there is sufficient clearance
when opening the rear doors. You could oth-
erwise damage the vehicle and objects in
close range of the rear doors.
You can lock the rear doors at an angle of 90°,
180° and 270°. Always make sure that the open
rear door is correctly engaged in the detent.

Changing bulbs
Important safety notes
GDANGER
Xenon bulbs carry a high voltage. You can get an electric shock if you remove the cover of
the Xenon bulb and touch the electrical con-
tacts. There is a risk of fatal injury.
Never touch the parts or the electrical con-
tacts of the Xenon bulb. Always have work on
the Xenon bulbs carried out at a qualified spe-
cialist workshop.
GWARNING
Bulbs, lamps and connectors can get very hot
when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before
changing a bulb.
!Make sure the bulbs are always securely
installed.
If your vehicle is equipped with Bi-Xenon bulbs,
you can recognize this by the following: the cone
of light from the Xenon bulbs moves from the
top to the bottom and back again when you start
the engine. For this to be observed, the low-
beam headlamps must be switched on before
starting the engine.
The bulbs and lamps are an essential compo-
nent of vehicle safety. You must therefore make
sure that these function correctly at all times.
Have the headlamp setting checked regularly.
RAlways switch off the vehicle's lighting sys-
tem before changing a bulb.
This will prevent a short circuit.
RDo not touch the glass tube of new bulbs with your bare hands. Always use a clean, lint-free
cloth or only touch the base of the bulb when
installing.
Even minor contamination can burn into the
glass surface and reduce the service life of the
bulbs.
RDo not use a bulb that has been dropped or
that has scratches on its glass tube.
The bulb could explode.
ROnly use bulbs in closed lamps which have
been designed for this purpose.
ROnly use spare bulbs of the same type and
with the prescribed voltage
RProtect the bulbs from moisture when in use.
If the new bulb still does not light up, consult a
qualified specialist workshop.
RHave the LEDs and bulbs of the following
lamps changed at a qualified specialist work-
shop:
-the additional turn signals in the exterior
mirrors
-the high-mounted brake lamp
-LED daytime running lamps (Bi-Xenon
headlamps)
-Bi-Xenon lamps (Bi-Xenon headlamps)
-front fog lamps
If you require assistance changing bulbs, con-
sult a qualified specialist workshop.

When loading your vehicle for driving off-road or
on a construction site, keep the vehicle's centerof gravity as low as possible.
Checklist before driving off-road
XCheck the fuel and DEF levels (Ypage 161)
and top up (Ypage 128).
XEngine: check the oil level (Ypage 221) and
add oil (Ypage 223).
Before driving up or down steep gradients, fill
the oil to the maximum level.
iIf you drive up or down steep gradients, the
4 symbol may appear in the display. The
engine operating safety is not put at risk if you
have filled the engine oil to the maximum level
before the journey.
XVehicle tool kit: check that the jack is work-
ing (Ypage 241).
XMake sure that a lug wrench (Ypage 241),
wooden underlay for the jack, a robust tow
cable and a folding spade are carried in the
vehicle.
XWheels and tires: check the tire tread depth
(Ypage 249) and tire pressure
(Ypage 251).
Rules for driving off-road
!Always bear the vehicle's ground clearance
in mind and avoid obstacles, e.g. deep ruts.
Obstacles may damage the following parts of
the vehicle:
Rthe chassis
Rthe drive train
Rthe fuel and supply tanks
For this reason, you should always drive
slowly when driving off-road. If you have to
drive over obstacles, have the front
passenger direct you.
iWe recommend that you additionally carry a
shovel and a recovery rope with shackle in the
vehicle.
REnsure that loads and items of luggage are
securely stowed or lashed down
(
Ypage 213).
RBefore driving off-road, stop the vehicle and
shift to a low gear.
RIf the surface demands it, temporarily deacti-
vate ASR when pulling away (Ypage 55).
ROnly drive off-road with the engine running
and a gear engaged.
RDrive slowly and smoothly. Walking pace is
necessary in many situations.
RAvoid spinning the drive wheels.
RMake sure that the wheels always remain in
contact with the ground.
RDrive with extreme care over unknown terrain
where you can only see for a short distance.
As a precaution, get out of the vehicle to take
a look at the route to be taken in advance.
RCheck the water depth before fording.
RWatch out for obstacles (e.g. rocks, holes,
tree stumps and ruts).
RAvoid edges where the surface could crumble
or break away.
Checklist after driving off-road
!If you detect damage to the vehicle after
driving off-road, have the vehicle checked
immediately at a qualified specialist work-
shop.
Off-road driving places a higher demand on your
vehicle than normal road operation. Check your
vehicle after driving on rough terrain. By doing
so you will notice any damage in good time and
reduce the risk of an accident for yourself and
other road users. Clean your vehicle thoroughly
before driving on public roads.
Observe the following points after driving off-
road, on construction sites and before driving on
public roads:
XVehicles with all-wheel drive: deactivate
all-wheel drive (Ypage 147).
XActivate ASR (Ypage 55).
XClean the headlamps and tail lamps and
check them for damage.
XClean the front and rear license plates.
XClean the windshield, windows and exterior
mirrors.
XClean the steps, door sills and grab handles.
This increases safety of footing.
XClean the wheels and tires, wheel arches and
the underbody of the vehicle with a water jet.
This increases road grip, especially on wet
road surfaces.

Towing a trailer
Notes on trailer towing
Important safety notes
GWARNING
Installing an unsuitable ball coupling may
result in overloading of the trailer tow hitch
and the rear axle. This applies especially if the ball coupling in question is longer or angled
differently. This could seriously impair the
driving characteristics and the trailer can
come loose. There is a risk of an accident.
You should only ever install a ball coupling
that has the permissible dimensions and that
is designed to meet your trailer-towing
requirements. Do not modify the ball coupling
or the trailer tow hitch.
GWARNING
If the ball coupling is not correctly installed
and secured, it could come loose while driving and endanger other road users. There is a risk
of an accident and injury.
Install and secure the ball coupling as descri-
bed in the ball coupling manufacturer's instal-
lation instructions. Make sure that the ball
coupling is correctly installed and secured
before every journey.
GWARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The vehi- cle/trailer combination could even rollover.
There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary.
Always observe the operating instructions pro-
vided by the manufacturers of the trailer cou-
pling and the ball coupling.
Couple and decouple the trailer carefully. When backing up the towing vehicle, make sure
154Towing a trailer
Driving and parking

ing to. Information is available from the police
and local authorities.
Observe the following when towing a trailer:
RPractice driving around bends, stopping and
backing up at a place where there is no traffic.This enables you to gain experience and get
used to the new handling characteristics.
RBefore driving, check:
-that the trailer tow hitch and ball coupling
are secure
-that the safety switch for a braked trailer is
functioning properly
-that the safety chains are secure and not
damaged
-that the electrical connections are secure
-that the lights are working
-that the wheels are in good order and the
tire pressure is correct
RAdjust the exterior mirrors to provide an
unobstructed view of the rear section of the
trailer.
RIf the trailer is equipped with an individual
braking system, check before each journey
whether the brakes are functioning correctly.
RIf the trailer has electronically controlled
brakes, pull the vehicle/trailer combination
away carefully. Brake manually using the
brake controller and check that the brakes
are working.
RSecure the load on the trailer according to the
applicable specifications and current stand-
ards on securing loads (
Ypage 215).
RWhen driving with a trailer, check at regular
intervals that the load is secured and that the
brakes and lights are working.
RBear in mind that the handling will be less
stable when towing a trailer than when driving
without one. Avoid sudden steering move-
ments.
RThe vehicle/trailer combination is heavier,
accelerates more slowly and has a decreased
gradient climbing capability and a long er
brak

ing distance.
It is more susceptible to crosswinds and
requires cautious steering.
RIf possible, do not brake suddenly, but rather
moderately at first so that the trailer can acti-
vate its brakes. Then increase the force on the
brake pedal.
RIf the automatic transmission repeatedly
shifts between gears when driving on inclines, restrict the shift range. Select shift range
4,3,
2 or 1.
Driving in a low gear and at a low speed
reduces the risk of damaging the engine.
RWhen driving on a downhill gradient, shift to a
low gear and take advantage of the engine's
braking effect.
Avoid continuous brake application as this
may overheat the vehicle brakes and, if instal-
led, the trailer brakes.
RIf the coolant temperature increases dramat-
ically while the air-conditioning system is
switched on, switch off the air-conditioning
system.
Coolant heat can also be dissipated by
switching the airflow and the temperature of
the heater/air conditioning to the maximum
level. Open the windows if necessary.
RWhen overtaking, pay particular attention to
the extended length of your vehicle/trailer
combination.
Due to the length of your vehicle/trailer com-
bination you need an additional distance
before you can return to your original lane.
Uncoupling a trailer
GWARNING
If you uncouple a trailer with the overrun
brake engaged, you could trap your hand
between the vehicle and the trailer drawbar.
There is a risk of injury.
Do not uncouple a trailer if the overrun brake
is engaged.
!Do not disconnect a trailer with an engaged
overrun brake. Otherwise, your vehicle could
be damaged by the rebounding of the overrun
brake.
XMake sure the selector lever of the automatic
transmission is in position P.
XApply the parking brake of the vehicle.
XClose all doors.
XApply the parking brake of the trailer.
XIn addition, secure the trailer against rolling
away with a wheel chock or similar object.
