Driving and operating133Drive 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
3 207 and are suitable for the
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
3 85.
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 notattempt to go as fast through turns as
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 3 204.

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

136Driving and operatinghard braking, the vehicle can nolonger 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
3 89.Drive away function
With the engine running, selecting a
forward gear (manual 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.

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.

138Driving and operating9Warning
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
button t briefly. Control indicator t
illuminates in the instrument cluster.
ESC is reactivated by pressing button 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.
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.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.

Driving and operating139
Activation
At speeds below approx. 30 mph,
press button u. The green control
indicator u flashes in the instrument
cluster, to show DCS is in operation.
DCS will not activate at speeds above 30 mph, even if the button is pressed.
Deactivation
Press button 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
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.

140Driving and operatingDriver assistance
systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation.
Cruise control
The cruise control can store and
maintain speeds above 25 mph.
Deviations from the stored speeds
may occur when driving uphill or
downhill.
For safety reasons the cruise control
cannot be activated until the foot
brake has been operated once.
Do not use the cruise control if it is not advisable to maintain a constant
speed.
With automatic transmission, only activate cruise control in automatic
mode.
Control indicator m 3 90.

Resume stored speed
Press the + RES button at a speed
above 25 mph. The stored speed will
be obtained.
Deleting the stored speed The stored speed will be deleted by
pressing the e button or
switching off the ignition.Parking assist
The parking assist system makes
parking easier by measuring the
distance between the vehicle and obstacles to the front and rear, and
giving acoustic signals. It is the driver,
however, who bears full responsibility for the parking manoeuvre.
The system consists of four ultrasonic
parking sensors in both the front and
rear bumpers.
Control indicator r 3 86.
Activation
With the ignition on, the system must
be activated manually.
Press button r on the instrument
panel. The LED in the button will
illuminate and will activate when a
forward gear or reverse gear is
engaged and the electrical parking
brake is released.
An obstacle is indicated by an
acoustic signal. The interval between
the sounds becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than

142Driving and operating
30 cm, the signal is continuous. The
acoustic signal may differ depending
on the type of object detected.
Deactivation
To deactivate, press the button again
and the LED in the button will
extinguish. The control indicator r
in the instrument cluster will illuminate
until the vehicle speed exceeds
18 mph.
The system is deactivated
automatically when the vehicle speed is above 5 mph or when selector leveris in neutral (automatic transmission
in N or P).
If the b button is pressed again, the
LED in the button will extinguish and
the system will be reactivated as soon
as a forward gear or reverse gear is
engaged and the electrical parking
brake is released.
Fault
In the event of a fault in the system,
control indicator r illuminates in the
instrument cluster.If the acoustic signal sounds 3 times
continuously when there are no
obstacles near the front or rear
bumper, there is a fault in the system. Have the cause of the fault remedied
by a workshop.
Important hints for using the
parking assist system9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Special attention has to be paid to
low obstacles which can damage
the lower part of the bumper.
Caution
Performance of the system can be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
system can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles in the vicinity
(e.g. off-road vehicles, mini vans,
vans). Object identification and correct distance indication in the
upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross-section, e.g. objects of
narrow size or soft materials, may
not be detected by the system.
Parking assist systems do not
detect objects outside the
detection range.
