Driving and operating
Automatic transmission
The automatic transmission permits
automatic gearshifting (automatic
mode) or instruction gearshifting
(instruction mode).
Transmission display
The transmission display is shown in
the Driver Information Centre 3 91,
located in the centre of the instrument
cluster.
The mode or selected gear is shown
in the transmission display.

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 Instruction mode.
-------------------------------------------------------------------------------------------------------------------------------------------------------------
Driving and operating
137
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
Parking
Apply the electrical parking brake and
engage P.
The ignition key can only be removed
when the selector lever is in position
P.
Sport mode
Suspension and steering become
more direct and provide better
contact with the road surface. The
engine reacts more quickly to
accelerator pedal movements.
Automatic gear changing is also more
responsive.
Sport mode can reduce the vehicle's
fuel economy. Use normal mode
whenever possible.
Note
Sport mode may be unavailable if
the charging level of the vehicle
battery is too low.
Activation
Press SPORT to switch on Sport
mode.

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 instruction mode can be
achieved whilst accelerating. If the
engine speed is too low, the
transmission will automatically shift to
a lower gear, even in instruction 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 instruction 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 increases engine
speed to quickly bring the
catalytic converter to the required
temperature.
Kickdown
In both automatic and instruction 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 3 122.
Fault
In the event of a fault in the automatic
transmission, control indicator Z
illuminates in the instrument cluster
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
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.

Driving and operating
Caution
It is not advisable to drive with the
hand resting on the selector lever.
Fuel economy mode 3 122.
Drive systems
All-wheel drive
All-wheel drive is an active-on-
demand system that engages
automatically, with no action required
by the driver. Depending on the
driving environment, the vehicle
switches between two-wheel drive
and four-wheel drive, to give the
vehicle more traction and stability
when necessary.
If the front wheels begin to slip, the
rear wheels will automatically begin to
drive the vehicle as required. More
torque is transferred to the wheels
that have the most traction, so the
vehicle has optimum grip at all times.
There may be a slight engagement
noise during hard use.
As well as enabling the vehicle to be
driven off-road, this system also
enables the vehicle to be driven on
normal roads without incurring
excessive tyre and drivetrain wear or
causing poor control.
Ensure tyres (including the spare) are
inflated to the correct pressure
prevailing road conditions. For
optimum system performance, the
vehicle's tyres should not have
varying degrees of wear.
If control indicator B flashes in the
instrument cluster during driving, All-
wheel drive is temporarily disabled. If
B
flashes continuously, there is a fault
in the system; seek the assistance of
a workshop.
All-wheel drive control indicator B
On-road driving
The increased traction of All-wheel
drive vehicles offers greater driving
control in adverse road conditions,
particularly heavy snow and ice.
However, All-wheel drive vehicles are
not "skid-proof" and do not decrease
stopping distances.
All-wheel drive vehicles have a higher
centre of gravity than conventional
vehicles. Always approach curves at
an appropriate driving speed. Do not
attempt to go as fast through turns as
-------------------------------------------------------------------------------------------------------------------------------------------------------------
Driving and operating
141
you might in a conventional vehicle.
Strong crosswinds can affect the
normal steering of the vehicle. Drive
slower under strong crosswind
conditions.
Off-road driving
● Avoid protruding objects (such as
rocks or tree stumps) that may
damage the underbody and tyres
of your vehicle.
● Test the brakes after operating in
mud, to clear excess mud from
the braking surfaces.
● Grip the steering wheel when
travelling over rough terrain.
Terrain conditions can cause
rapid and unexpected movement
in the steering.
The ground clearance, ramp angle,
angle of approach and departure and
wading depth need to be considered,
especially in hilly conditions and
when wading, to prevent the vehicle
becoming stuck and possibly
damaged.
Vehicle dimensions 3 209.
Towing the vehicle 3 196.
Driving through water
Do not exceed the maximum wading
depth 3 209.
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 5 km/h, 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 3 120. 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 service
operations 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 over
mechanical components and cause
localised overheating and failure of
parts, especially in the engine
compartment.
-------------------------------------------------------------------------------------------------------------------------------------------------------------
142
Driving and operating
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
● 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
tank
Brakes
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 85.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.
-------------------------------------------------------------------------------------------------------------------------------------------------------------
Driving and operating
143
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.
Fault
9 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
hard braking, the vehicle can no
longer be steered and may
swerve.
You can continue driving, provided
you drive with care and anticipation.
Have the cause of the fault remedied
by a workshop.
Parking brake
Electrical parking brake
Applying when vehicle is stationary
Pull switch m, the electrical parking
brake operates automatically with
adequate force. For maximum force,
e.g. parking with a trailer or on
inclines, pull switch m twice.
The electrical parking brake can
always be activated, even if the
ignition is off.
Do not operate electrical parking
brake system too often without
engine running as this will discharge
the battery.
Before leaving the vehicle, check the
electrical parking brake status.
Control indicator m 3 85.
Releasing
Switch on ignition. Keep foot brake
depressed and then push switch m.
If the foot brake is not depressed
when attempting to release electrical
parking brake, a warning chime will
sound and control indicator -
illuminates in the instrument cluster
-------------------------------------------------------------------------------------------------------------------------------------------------------------
144
Driving and operating
Drive away function
With the engine running, selecting a
forward gear (instruction transmission)
or engaging D (automatic
transmission) and then depressing
the accelerator pedal automatically
releases the electrical parking brake.
This is not possible when the switch
m
is pulled at the same time.
This function also helps driving away
on inclines.
Aggressive drive away may reduce
life time of wear parts.
Dynamic braking when vehicle is
moving
When the vehicle is moving and the
switch m is kept pulled, a warning
chime will sound and the electrical
parking brake system will decelerate
the vehicle, but will not apply
statically.
As soon as the switch m is released,
dynamic braking will be stopped.
Fault
Failure mode of electrical parking
brake is indicated by control indicator
j
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 vehicle
movement. 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 unintended
movement 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.
-------------------------------------------------------------------------------------------------------------------------------------------------------------
Driving and operating
145
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 87.
9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
Deactivation
With ESC active, if wheels are
slipping on wet, snowy or icy roads,
engine speed may not increase when
accelerator pedal is depressed. The
vehicle may not move.
Switch off ESC function, to allow
engine rpm to increase, by pressing
t
briefly. Control indicator t
illuminates in the instrument cluster.
ESC is reactivated by pressing t
again. The control indicator
extinguishes.
Control indicator t 3 87.
Hydraulic brake assist
When the ESC function comes into
action and recognises any
emergency situation requiring hard
braking, it automatically delivers
increased braking pressure to the
wheels.
Active rollover protection
If the vehicle moves in an unstable
manner, this function helps the
vehicle maintain normal stability.
-------------------------------------------------------------------------------------------------------------------------------------------------------------
146
Driving and operating
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.
Fault
If there is a fault in the system the
control indicator b illuminates
continuously. The system is not
operational.
Have the cause of the fault remedied
by a workshop.
Descent control system
The Descent control system (DCS)
allows the vehicle to travel at a low
speed without depressing the foot
brake. The vehicle will automatically
decelerate to a low speed and remain
at that speed when the system is
activated. Some noise or vibration
from the brake system may be
apparent when the system is active.
Caution
Use only when descending steep
grades while driving off-road. Do
not use when driving on normal
road surfaces. Unnecessary
usage of the DCS function, such
as while driving on normal roads,
may damage the brake system
and the ESC function.
Activation
At speeds below approx. 50 km/h,
press u. The green control indicator
u
flashes in the instrument cluster, to
show DCS is in operation. DCS will
not activate at speeds above
50 km/h, even if the button is pressed.
Deactivation
Press u again. The green control
indicator u extinguishes. Depressing
the foot brake or accelerator will also
cause the system to be deactivated.
Fault
The yellow control indicator u flashes
to indicate that the system is not
ready for conditions to operate, due to
the high temperature (approx.
350 - 400 °C) of friction material,
through severe or repeated braking. It
will extinguish when the temperature
drops below 350 °C.
The yellow control indicator u
illuminates when there is a
malfunction in the system, due to the
extremely high temperature
(over 400 °C) of friction material,
through severe or repeated braking. It
will extinguish when the temperature
drops below 350 °C. These
-------------------------------------------------------------------------------------------------------------------------------------------------------------
Driving and operating
147
temperatures may differ according to
vehicle conditions or outside
conditions.
Flashing or illumination of the yellow
control indicator u reminds the driver
that the friction material needs to cool
down: drive the vehicle without
braking as much as possible. If the
control indicator does not extinguish,
have the cause of the fault remedied
by a workshop.
DSC control indicators u 3 86.
Automatic level control
The rear level of the vehicle is
automatically adjusted to the load
conditions while driving. Suspension
and ground clearance are increased,
which improves driving conditions.
The automatic level control is
activated after the vehicle has been
driven for some distance, depending
on the vehicle load and the road
conditions.
Do not use full payload in the event of
a fault. Have the cause of the fault
remedied by a workshop.
Headlight range adjustment 3 106.
