134Driving and operatingDrive 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.

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 maydamage 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.

140Driving and operating
Activation
At speeds below approx. 50 km/h,
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 50 km/h, 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 87.
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.
