Intelligent Light System* (bi-xenon
headlamps*) The Intelligent Light System is a system which
adjusts the headlamps automatically to suit
the prevailing driving and weather conditions.
The bi-xenon headlamps offer enhanced func-
tions to improve illumination of the road sur-
face, e.g. depending on the vehicle speed or
weather conditions. The system includes the
active light function, motorway mode and
extended range foglamps. The system is only
active when it is dark.
You can activate or deactivate the "Intelligent
Light System" using the on-board computer
(Y page 106). Active light function The active light function is a system that
moves the headlamps according to the steer-
ing movements of the front wheels. In this
way, relevant areas remain illuminated while
driving. This allows you to recognise pedes-
trians, cyclists and animals.
Motorway mode
Motorway mode increases the range of the
beam.
Active:
R
If you are driving at speeds above
110 km/ha nd do not make any large steer-
ing movements for 1000 m.
R If you are driving at speeds above
130 km/h.
Motorway mode remains active unless your
speed drops speeds below 80 km/h.
Not active: if you are driving at speeds below
80 km/h. 82

X
Wheels and tyres: check the tyre tread
depth and tyre pressure.
X Check for damage and remove foreign
objects, e.g. small stones, from the
wheels/tyres.
X Replace any missing valve caps.
X Replace dented or damaged wheels.
Checklist after driving off-road Driving over rough terrain places greater
demands on your vehicle than driving on nor-
mal roads. After driving off-road, check the
vehicle. This allows you to detect damage
promptly and reduce the risk of an accident
to yourself and other road users.
X Deactivate the LOW RANGE off-road gear
(Y page 114).
X Deactivate DSR (Y page 113).
X Set the differential lock setting to AUTO on
the selector wheel (Y page 116).
X Lower the vehicle level again to a level suit-
able to the road conditions, e.g. to the high-
way/high-speed level.
X Clean the headlamps and rear lights and
check for damage.
X Clean the front and rear licence plates.
X Clean the wheels/tyres with a water jet and
remove any foreign objects.
X Clean the wheels, wheel arches and the
vehicle underside with a water jet; check
for foreign objects and damage.
X Check whether twigs or other parts of
plants have become trapped. These
increase the risk of fire and can damage
fuel pipes, brake hoses or the rubber bel-
lows of the axle joints and propeller shafts.
X After the trip, examine without fail the
entire undercarriage, wheels, tyres, brakes,
bodywork structure, steering, chassis and
exhaust system for damage.
X After driving for extended periods across
sand, mud, gravel, water or in similarly dirty
conditions, have the brake discs, wheels, brake pads/l
inings and axle joints checked
and cleaned.
X If you detect strong vibrations after off-road
travel, check for foreign objects in the
wheels and drive train and remove them if
necessary. Foreign objects can disturb the
balance and cause vibrations. Travelling uphill

R
Drive quickly to overcome the rolling resist-
ance. The vehicle could otherwise dig itself
into the sand.
R Drive in the tracks of other vehicles, if pos-
sible. Make sure that the ruts are not too
deep, that the sand is firm enough and that
your vehicle has sufficient ground clear-
ance. Ruts
Observe the following rules when driving
along ruts in off-road terrain or on roads with
loose gravel:
! Check that the ruts are not too deep and
that your vehicle has sufficient clearance.
Otherwise, your vehicle could be damaged
or bottom out and get stuck.
R Select the LOW RANGE off-road gear
(Y page 114).
R Select a higher vehicle level.
R Avoid high engine speeds.
R Select shift range 1.
R Drive slowly.
R Where ruts are too deep, drive with the
wheels on one side on the middle section
of turf if possible. Driving abroad
Points to remember
An extensive Mercedes-Benz Service network
is also available in other countries. The
Service Hotline's current telephone numbers
for use when you are abroad are to be found
in the "Service24h" chapter of the Service
Booklet.
Only low-octane fuel is available in certain
countries.
You can find further information about fuel
grades on (Y page 172). Symmetrical dipped beam
If your journey takes you to countries where
vehicles are driven on sides of the road oppo-
site to the country in which the vehicle is reg-
istered, your headlamps must be switched to
symmetrical dipped beam. Oncoming traffic
will be dazzled less.
X Have the headlamps switched over at a
qualified specialist workshop, e. g. a
Mercedes-Benz Service Centre. G
Risk of accident
Remember to set the headlamps back to
asymmetrical dipped beam when you return
to driving on the same side of the road as that
of the country in which your vehicle was reg-
istered. You may otherwise dazzle the oncom-
ing traffic and could cause an accident. Trailer towing*
Folding out the ball coupling
Before you can tow a trailer with your vehicle,
you must fit the ball coupling.
The telescopic lever is under the boot/lug-
gage compartment mat on the left-hand side. G
Risk of accident
Make sure that the ball coupling is fully
engaged both when it is folded in and when it
is folded out. The indicator lamp is not lit.
Do not pull the telescopic lever if a trailer is
attached. The trailer could otherwise come
loose. Trailer towing*

Do not clean the wiper blades too often,
and avoid rubbing too hard, as this could
result in damage to the graphite coating.
This could cause wiper noise.
X Fold the wiper arms away from the wind-
screen.
X Clean the wiper blades carefully with a
damp cloth.
X Fold the wiper arms back again before
switching on the ignition.
Cleaning the headlamps X
Clean the plastic lenses of the headlamps

scratch or damage the plastic lenses of the
headlamps.
Cleaning the sensors* X
Clean sensors :for the driving systems
with water, car shampoo and a soft cloth. !
If you clean the sensors using a high-pres-
sure cleaner or steam cleaner, observe the
manufacturer's information on maintaining
the correct distance between the vehicle
and the high-pressure cleaner.
Cleaning the reversing camera* X
Use clear water and a soft cloth to clean
camera lens :.
! Do not clean the camera lens and the area
around the reversing camera with a high-
pressure cleaner.
Cleaning the exhaust tail pipes Impurities combined with the effects of road
grit and corrosive environmental factors may
cause flash rust to form on the surface. Reg-
ular care of the exhaust tail pipes will ensure
that their original shine is restored.
!
Do not clean the exhaust tail pipes with
alkaline-based cleaning agents such as
wheel cleaner.
X Clean the exhaust tail pipes with a chrome
care product approved by Mercedes-Benz.
Trailer coupling* The ball coupling must be cleaned if it
becomes dirty or corroded.
