■ Transfer box and underguard
■ Engine oil pan and underguard
Observe the following: ■ Do not spray high-pressure water directly at the vehicle seals
■ The wheels must be removed to clean all mud and stones from the
brake calipers and to check brake
pad wear
■ The areas on the upper side of the underguards must be cleared of
stones, to prevent damage to the
engine oil pan and the fuel tankBrakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek the assistance of a workshop before
continuing your journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 84.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.ABS starts to regulate brake pressure as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting off, the system performs a self-test which may be audible.
Control indicator u 3 85.
Fault9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During

Tyre pressureCheck 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.
Use the valve cap key to make
unscrewing the valve caps easier.
The valve cap key is located on the
inside of the tank flap.
Tyre pressure 3 207.
The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare tyre to the
pressure specified for full load.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
The tyre pressure tables show all
possible tyre combinations 3 207.
For the tyres approved for your
vehicle, refer to the EEC Certificate of
Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
If the tyre pressure shall be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition.
Tyre pressure monitoring
system The tyre pressure monitoring system
checks the pressure of all four wheels
once per minute when vehicle speed
exceeds a certain limit.Caution
Tyre pressure monitoring system
warns only about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure. If
wheels without sensors are mounted,
the tyre pressure monitoring system
is not operational. Retrofitting of
sensors is possible.
Notice
In countries where the tyre pressure monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.

Vehicle care191
If using a car wash, comply with the
car wash manufacturer's instructions.
The windscreen wiper and rear
window wiper must be switched off.
Remove antenna and external
accessories such as roof racks etc.
If you wash your vehicle by hand,
make sure that the insides of the
wheel housings are also thoroughly
rinsed out.
Clean edges and folds on opened
doors and the bonnet as well as the
areas they cover.Caution
Always use a cleaning agent with
a pH value of 4 to 9.
Do not use cleaning agents on hot surfaces.
Have the door hinges of all doors
greased by a workshop.
Do not clean the engine compartment with a steam-jet or high-pressure jet
cleaner.
When cleaning with a high-pressure
jet cleaner, ensure a minimum
distance of 30 cm when working
around the tailgate to prevent
unintended unlocking.
Thoroughly rinse and leather-off the
vehicle. Rinse leather frequently. Use
separate leathers for painted and
glass surfaces: remnants of wax on
the windows will impair vision.
Exterior lights
Headlight and other light covers are
made of plastic. Do not use any
abrasive or caustic agents, do not use an ice scraper, and do not clean them
dry.
Polishing and waxing Wax the vehicle regularly (at the
latest when water no longer beads).
Otherwise, the paintwork will dry out.
Polishing is necessary only if the paint
has become dull or if solid deposits
have become attached to it.
Paintwork polish with silicone forms a
protective film, making waxing
unnecessary.Plastic body parts must not be treated with wax or polishing agents.
Windows and windscreen wiper blades
Use a soft lint-free cloth or chamois leather together with window cleanerand insect remover.
When cleaning the rear window,
make sure the heating element inside
is not damaged.
For mechanical removal of ice, use a
sharp-edged ice scraper. Press the
scraper firmly against the glass so
that no dirt can get under it and
scratch the glass.
Clean smearing wiper blades with a
soft cloth and window cleaner.
Sunroof
Never clean with solvents or abrasive
agents, fuels, aggressive media
(e.g. paint cleaner, acetone-
containing solutions etc.), acidic or
highly alkaline media or abrasive
pads. Do not apply wax or polishing
agents to the sunroof.
