Driving and operating135
■ 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
Driving and operating137
Fault
Failure mode of electrical parking
brake is indicated by control indicator
j 3 85.
In the event of a fault, to apply
electrical parking brake: pull and hold the switch m for a few seconds. If
control indicator m illuminates,
electrical parking brake has been
applied successfully.
To release electrical parking brake:
push and hold the switch m for a few
seconds. If control indicator m
extinguishes, electrical parking brake has been released successfully.
If control indicator m flashes:
electrical parking brake is not fully
applied or released. When m is
continuously flashing, with ignition
switched on depress brake pedal,
release electrical parking brake and
retry applying.
If m continues to flash, do not drive
the vehicle. If necessary, place
wedge blocks or equivalent in front of and behind wheels to prevent vehiclemovement. Seek the assistance of a
workshop to have the cause of the
fault remedied.
Brake assist
If the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the brake pedal for as long as full braking is required. Maximum brake force is
automatically reduced when the
brake pedal is released.
Hill start assist The system helps prevent unintendedmovement when driving away on
inclines.
When releasing the foot brake after
stopping on an incline, the brakes
remain on for a further 2 seconds. The brakes release automatically as soon
as the vehicle begins to accelerate.Ride control systems
Electronic Stability Control Electronic Stability Control (ESC)
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip. It also
prevents the drive wheels from
spinning.
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the wheels are braked individually. This
considerably improves the driving
stability of the vehicle on slippery road
surfaces.
ESC is operational as soon as control indicators b and t extinguish in the
instrument cluster after switching on the ignition.
When ESC is active b flashes 3 86.
146Driving and operatingTrailer hitch
General information
The coupling ball bar is kept in a bag,
fastened with a strap and is stowed
below the floor cover in the load
compartment.
Only use towing equipment that has
been approved for your vehicle.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
Control indicator á illuminates in the
instrument cluster when a trailer is
connected to the vehicle 3 90.
Driving characteristics and
towing tips In the case of trailers with brakes,
attach the break-away stopping cable
to the eye - not to the coupling ball
bar.If no eye is available, loop cable
around coupling ball bar. Ensure
cable is crossed under the vertical
coupling socket to ensure the trailer
nose cannot drop to the ground if it
becomes separated from the trailer
hitch. Do not allow the cable to drag
along the ground and always allow
enough slack to permit full turning.
Follow the instructions supplied with
the towing equipment.
Before attaching a trailer, lubricate
the coupling ball. However, do not do
so if a stabiliser, which acts on the coupling ball, is being used to reduce snaking movements. For trailers with
low driving stability, the use of a
friction-type stabiliser is strongly
recommended.
Do not drive faster than 50 mph, even
in countries where higher speeds are
permitted. When driving uphill, do not drive faster than 20 mph in 1st gear,
or 30 mph in 2nd gear.
If the trailer starts snaking, drive more slowly, do not attempt to correct the
steering and brake sharply if
necessary.When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 207.
Trailer towing Trailer loads
The permissible trailer loads are
vehicle-dependent and engine-
dependent maximum values which
must not be exceeded. The actual
trailer load is the difference between
the actual gross weight of the trailer
and the actual coupling socket load
with the trailer coupled.
When the trailer load is being
checked, therefore, only the trailer
wheels - and not the jockey wheel -
must be standing on the weighing
apparatus.
The permissible trailer loads are
specified in the vehicle documents. In general, they are valid for gradients
up to max. 12 %.
Driving and operating1499Warning
Towing a trailer is permitted only
when the coupling ball bar is fitted correctly. If the coupling ball bar
cannot be properly attached, seek the assistance of a workshop.
Eye for break-away stopping cable
In the case of trailers with brakes,
attach the break-away stopping cable
to the eye - not to the coupling ball
bar.
Dismounting the coupling ball bar
Unlock coupling ball bar and remove
key. Push lever to the left, towards the
coupling ball bar and turn it
downwards. Pull coupling ball bar out of coupling housing.
Remove any rust or dirt from area
around the coupling housing and
coupling ball bar connection before
inserting sealing plug in the hole.
Place the coupling ball bar in the bag supplied, fasten it with the strap and
stow it below the floor cover in the
load compartment.
Do not use steam-jet cleaners or
other high-pressure cleaners to clean
the coupling ball bar.
Trailer stability assist If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is
selectively braked until the snaking ceases. While system is working keep steering wheel as still as possible.
Trailer stability assist (TSA) is a
function of the Electronic Stability
Control 3 137.
Vehicle care155Washer fluid
Fill with clean water mixed with a
suitable quantity of washer fluid which
contains antifreeze. For the correct mixing ratio refer to the washer fluid
container.
Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
Do not spray washer fluid onto
windscreen in freezing weather, to avoid ice forming and impairing
vision.
In cold weather, do not fill the washer
fluid reservoir more than three
quarters full, to allow enough room for expansion if the fluid freezes, and to
prevent damage to the reservoir.
Brakes In the event of minimum thickness of
the brake lining, a squealing noise
sounds during braking.
Continued driving is possible but
have the brake lining replaced as
soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.Brake fluid9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes, skin, fabrics and painted surfaces.
The brake fluid level must be betweenthe MIN and MAX marks.
When topping up, ensure maximum cleanliness as contamination of the
brake fluid can lead to brake system
malfunctions. Have the cause of the
loss of brake fluid remedied by a
workshop.
