Obstacles may damage the following parts
of the vehicle:
R
the chassis
R the drive train
R the 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 co-driver
direct you.
i We recommend that you additionally
carry a shovel and a recovery rope with
shackle in the vehicle.
R Ensure that loads and items of luggage are
securely stowed or lashed down
(Y page 232).
R Before driving off-road, stop the vehicle and
shift to a low gear.
R If the surface demands it, temporarily
deactivate ASR when pulling away
(Y page 58).
R Only drive off-road with the engine running
and a gear engaged.
R Drive slowly and smoothly. Walking pace is
necessary in many situations.
R Avoid spinning the drive wheels.
R Make sure that the wheels always remain
in contact with the ground.
R Drive 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.
R Check the water depth before fording.
R Watch out for obstacles (e.g. rocks, holes,
tree stumps and ruts).
R Avoid 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
workshop. 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 yourselfa
nd otherroad 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:
X Activate ASR (Y page 58).
X Clean the headlamps and tail lamps and
check them for damage.
X Clean the front and rear license plates.
X Clean the windshield, windows and exterior
mirrors.
X Clean the steps, door sills and grab
handles.
This increases safety of footing.
X Clean the wheels/tires, wheel housings
and the underbody of the vehicle with a
water jet.
This increases road grip, especially on wet
road surfaces.
X Check the wheels/tires and wheel
housings for trapped foreign objects and
remove them.
Trapped foreign objects can damage the
wheels/tires and may be flung out from the
vehicle when you continue driving.
X Check the underbody for trapped branches
or other parts of plants and remove them.
Trapped branches or other parts of plants
increase the risk of fire and can cause
damage to fuel lines, brake hoses and the
rubber bellows of axle jointsa nd drive
shafts.
X Clea nthe brake disks, brake pads and axle
joints, particularly after operation in sand,
mud, grit/gravel, water or similarly dirty
conditions.
X Check the entire floor assembly, the tires,
wheels, bodywork structure, brakes, 154
Driving tipsDriving and parking
steering, chassis and exhaust system for
any damage.
X Check the service brake for operating
safety, e.g. carry out a brake test.
X If you notice strong vibrations after driving
off-road, check the wheels and drive train
for foreign objects again. Remove any
foreign objects which can lead to
imbalances and thus cause vibrations. Driving systems
Cruise control
Important safety notes Observe the notes on braking in the "Driving
tips" section (Y
page 150).
If you fail to adapty our driving style or if you
are inattentive, cruise control can neither
reduce the risk of an accident nor override the
laws of physics. Cruise control cannot take
road, weather and traffic conditions into
account .Cruise control is only an aid.Y ou are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in
good time.
Do not use cruise control:
R in traffic conditions that are unsuitable for
driving at a constant speed, e.g. in heavy
traffic, on winding roads or off-road
R on slippery roads. Brakin goraccelerating
may cause the drive wheel sto lose traction
and the vehicle could then skid.
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
If there is a change of drivers, make sure that
you inform the new driver about the set cruise
speed.
General notes Cruise control maintains the speed of the
vehicle for you.
Use cruise control if road and traffic
conditions make it appropriate to maintain a steady speed for a prolonged period. You can
set any speed from 20 mph upwards in
increments of 1 mph.
Use cruise control if road and traffic
conditions make it appropriate to maintain a
steady speed for a prolonged period. You can
set any speed from 20 mph upwards in
increments of 1 mph.
i
If you have set km/h as the unit for the
digital speedometer (Y page 185), you can
set any speed from 30 km/h upwards in
increments of 1 km/h.
i Cruise control should not be activated
when driving off-road or on construction
sites.
Cruise control may not be able to maintain
the stored speed on uphill or downhill
gradients. If the gradient evens out and the
vehicle's speed does not fall below 20 mph
(30 km/h), the stored speed is resumed.

WARNING
If you call up the stored speed and it differs
from the current speed, the vehicle
accelerates or decelerates. If you do not know
the stored speed, the vehicle could accelerate
or brake unexpectedly .There is a risk of an
accident. Pay attention to the road and traffic
conditions before calling up the stored speed.
If you do not know the stored speed, store the
desired speed again.
X Briefly pull the cruise control lever towards
you 0006.
X Release the accelerator pedal.
Cruise control is activated and resumes the

Important safety notes PARKTRONIC is only an aid. It cannot replace
your own awareness of the immediate
surroundings. You are responsible for safe maneuvering, parking and pulling away. When
maneuvering, parking and pulling away, make
sure that there are no persons, animals or
objects in the maneuverin
garea.
PARKTRONIC does not account for obstacles
that are:
R beneath its detection range, e.g. persons,
animals or objects
R above its detection range, e.g. overhanging
loads, overhangs or truck loading ramps
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates the distance
between yourv ehicle and an objec tvisually
and audibly.
Your vehicle features two separate sound
emitters with different frequencies for the
warning tones. The warning ranges in front of
and behind the vehicle are indicated by
different warning tones.
PARKTRONIC is activated automatically when
you:
R tur nthe key to position 2in the ignition lock
R release the parking brake and
R move the selector lever to D,Nor R.
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). PARKTRONIC is
reactivated at speeds below 10 mph
(16 km/h).
PARKTRONIC monitors the area around your
vehicle with sensors in the front and rear
bumpers.
Range of the sensors !
Pay particular attention to obstacles
above or below the sensors when parking,
such as flower pots or trailer towbars.
PARKTRONIC does not recognize such
objects when they are in the immediate
vicinity of the vehicle. You could damage
the vehicle or objects. Driving systems

Important safety notes G
WARNING
If you install a ball coupling other than the one
delivered with the vehicle, the trailer tow hitch
and the rear axle may be overloaded. 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.
Only install the ball coupling delivered with
the vehicle or a ball coupling that is designed
to meet your trailer towing requirements. Do
not modify the ball coupling or the trailer tow
hitch. G
WARNING
If you use a ball coupling that is not approved
for your vehicle, it may cause excessive strain
on the trailer tow hitch. This can cause
damage to the vehicle and the trailer may
come loose during the journey. The handling
may be impaired and the rear axle may be
overloaded. This may lead to an accident
involving serious or even fatal injury. Therefore note the following:
R
Only install a ball coupling that is approved
for your vehicle.
R Before the journey, make sure that the ball
coupling is correctly installed and secured.
To do this, observe the operating
instructions of the ball coupling
manufacturer.
R Do not make any modifications to the ball
coupling or the trailer tow hitch.
You must observe the operating instructions
