may be a fault in the diesel particle
filter 3 84. Cleaning is not possible,
seek the assistance of a workshop
immediately.Caution
If the cleaning process is
interrupted, there is a risk of
provoking severe engine damage.
Cleaning takes place quickest at high engine speeds and loads.
Do not switch off the engine until the
cleaning process is complete. This is
indicated by the extinguished control
indicator %.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
Caution
Fuel grades other than those listed on pages 3 143, 3 202 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.

Never shift to P or R while the vehicle
is moving.
The engine can only be started with
lever in position P or N. Depress foot
brake or apply electrical parking
brake before starting.
Do not accelerate while engaging a
gear. Never depress the accelerator
pedal and brake pedal at the same
time.
When a gear is engaged, the vehicle
slowly begins to creep when the foot
brake is released.
Engine braking To utilise the engine braking effect,
select a lower gear in good time when
driving downhill - see Manual mode.
Use of the engine braking effect, as
opposed to the use of the foot brake
when driving downhill, can extend the
life of the brakes.Rocking the vehicle
Rocking the vehicle is only
permissible if the vehicle is stuck in
water, ice, sand, mud, snow or a dip.
Move the selector lever between D
and R in a repeat pattern while
applying light pressure to the
accelerator pedal when the vehicle is in gear. Do not race the engine and
avoid sudden acceleration.
If the vehicle cannot be released after
rocking the vehicle several times,
your vehicle may need to be towed
3 188.
Parking
Apply the electrical parking brake and engage P.
The ignition key can only be removed
when the selector lever is in position
P .
130Driving and operatingManual mode
Move selector lever out of position D
towards the left and then forwards or backwards.
<=Shift to a higher gear.]=Shift to a lower gear.
Tip selector lever in the appropriate
direction. It then returns to the centre
position.
Gearshifting in manual mode can be
achieved whilst accelerating. If the
engine speed is too low, the
transmission will automatically shift to a lower gear, even in manual mode,
to prevent the engine from stalling.
If a higher gear is selected when
vehicle speed is too low, or a lower
gear when vehicle speed is too high,
the shift is not executed.
In manual mode, no automatic
shifting to a higher gear takes place
at high engine revolutions.
Gears can be skipped by moving the selector lever repeatedly at short
intervals.
After stopping, 1st gear is
automatically selected. When starting
on slippery surfaces, tip selector lever forwards to engage 2nd gear.
To move back to position D, move
selector lever back to the right.
Electronic driving
programmes ■ Following a cold start, the operating
temperature programme increasesengine speed to quickly bring the
catalytic converter to the required
temperature.Kickdown
In both automatic and manual modes, if the accelerator pedal is pressed
down completely the transmission
shifts to a lower gear depending on
engine speed. Full engine power is
available for acceleration.
Fuel economy mode
Activate fuel economy mode to allow
the transmission to adapt gearshift
patterns, improving the vehicle's fuel
economy.
Driving and operating131
Activation
In automatic mode, press button
s ; control indicator s
illuminates in the instrument cluster 3 88.
The settings of certain electronic
systems are adapted to reduce fuel
consumption:
■ The engine reacts less quickly to the accelerator pedal.
■ Automatic upshift points occur sooner and downshift points occur
later.
■ The transmission locks itself to the engine at cruising speeds, to
improve efficiency and increase
power and torque.
■ The fuel supply is automatically cut-
off more quickly during vehicle
deceleration. Overrun cut-off
3 124.
Do not use fuel economy mode whilst towing, e.g. a trailer.Deactivation
Fuel economy mode is switched off
by pressing button s again;
control indicator s extinguishes in
the instrument cluster.
Fault
In the event of a fault in the automatic
transmission, control indicator Z
illuminates in the instrument cluster 3 84 . Automatic shifting may be much
harsher than normal or, in the case of
a serious fault, cancelled altogether.
Have the cause of the fault remedied
by a workshop.
If control indicator g illuminates in
the instrument cluster when the
engine is running, this may indicate a
fault in the transmission electronics
3 84. The electronics switch to the
emergency running programme, fuel
consumption may increase and the
driveability of the vehicle may be
affected. Seek the assistance of a
workshop.Interruption of power
supply
The clutch is not disengaged if the
vehicle battery is discharged and a
gear has been selected. The vehicle
cannot move. The selector lever
cannot be moved out of position P or
N .
If the battery is discharged, start the
vehicle using jump leads 3 187.
If the battery is not the cause of the
fault, release the selector lever:
1. Switch off ignition and remove the
key.
2. Depress and hold foot brake.
134Driving and operating
Towing the vehicle 3 188.
Driving through water
Do not exceed the maximum wading
depth 3 204.
Check the depth of water: choose the
lowest entry and departure angles
before entering. Maintain a steady
engine speed, to help prevent water
from entering the exhaust system, but do not exceed 3 mph, to avoid
splashing the water.
Drive with the flow wherever possible,
not against it. If you have to drive
against the flow, try to drive at an
angle to it, so that the leading corner
of the vehicle will help deflect water
from the engine compartment. Avoid
splashing the water - if the ignition
system becomes wet, the engine may
stall.
Avoid water entering the air intake
system. If water enters the air intake
system, engine seizure with severe
costly damage may result.
Test the brakes after leaving the
water - wet brakes are less effective
than dry ones. Perform the serviceoperations for wading , involving
checks for water contamination, at
the earliest opportunity.
Service checks after wading
Check for the ingress of water into the following:
■ Brake fluid reservoir
■ Air cleaner element
■ Engine
■ Transmission
■ Axles
■ Interior of vehicle
Renew any lubricating oil or hydraulic
fluid that has a milky appearance,
indicating contamination with water.
Cleaning
Clean the vehicle thoroughly and as
soon as possible after driving off-
road.
Do not let mud remain dry on any part
of the vehicle as it becomes abrasive
and can damage paint, glass, seals,
bearings and brake components. If
left to build up, mud can seriously
affect the airflow through and overmechanical components and cause
localised overheating and failure of
parts, especially in the engine
compartment.
Ensure the radiator core and the area between the radiator and intercooler/
oil cooler (where installed) is cleaned, to maintain proper cooling air flow.
Check the radiator and cooler cores
for blockage (sand, silt etc.).
Check the tyre treads.
Clean and check the mechanical
parts of the vehicle, particularly the following areas:
■ Driveshafts, including sealing bellows
■ Front brake calipers, pads and discs
■ Front suspension
■ Clutch fork sealing bellows
■ Rear brake calipers, pads and discs
■ Rear suspension
■ Fuel tank and underguard
■ Breathers, axles and fuel tank
■ Load sensing valve
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
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 operating147
The permitted trailer load applies up
to the specified incline and up to an
altitude of 1000 metres above sea
level. Since engine power decreases
as altitude increases due to the air
becoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10 % for every 1000 metres of additional
altitude. The gross train weight does
not have to be reduced when driving
on roads with slight inclines (less than 8 %, e.g. motorways).
The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 198.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
The maximum permissible vertical
coupling load (80 kg) is specified on
the towing equipment identification
plate and in the vehicle documents.
Always aim for the maximum load,especially in the case of heavy
trailers. The vertical coupling load
should never fall below 25 kg.
When measuring the vertical coupling load, ensure the drawbar of the
loaded trailer is at the same height as
it will be when the trailer is coupled
with the towing vehicle loaded. This is
particularly important for trailers with
tandem axle.
Rear axle load When the trailer is coupled and the
towing vehicle is fully loaded
(including all occupants), the
permissible rear axle load (see
identification plate or vehicle
documents) must not be exceeded.
National regulations regarding
maximum speeds for vehicles towing a trailer must be observed.Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.
Towing equipment with
detachable coupling ball bar The coupling ball bar is kept in a bag,
fastened with a strap and is stowed
below the floor cover in the load
compartment.
