Drive systems
All-wheel drive
The All-wheel drive system enhances
driving characteristics and stability,
and helps to achieve the best
possible driveability regardless of
ground surface. The system is always
active and cannot be deactivated.
The torque is distributed steplessly
between the wheels of the front and rear axle, depending on the driving
conditions. Additionally the torque
between the rear wheels is distributed
depending on the surface.
For optimum system performance,
the vehicle's tyres should not have
varying degrees of wear.
If a service message is displayed in
the Driver Information Centre, the
system may have limited functionality (or be completely disabled in some
cases, i.e. the vehicle switches to
Front-wheel drive). Seek the
assistance of a workshop.
Towing the vehicle 3 268.
200Driving and operating
The advanced parking assist system
manoeuvres the driver into a parking slot by giving instructions on the
Driver Information Centre and
acoustic signals. The driver must
control acceleration, braking, steering
and gear shifting.
The system uses the sensors of the
parking assist system in combination
with two additional sensors on both
sides of the front and rear bumper.
Activation
When searching for a parking slot, the
system is ready to operate by
pressing button (.
The system can only be activated at
a speed up to 30 km/h and the system searches for a parking slot at a speed
up to 30 km/h.
The maximum allowed parallel
distance between the vehicle and a
row of parked cars is 1.8 metres.
Functionality
When the vehicle passes a row of
cars and the system is activated, the
advanced parking assist system
begins looking for a suitable parking
slot. When a suitable slot is detected, a visual feedback and acoustic
signals are given in the Driver
Information Centre.
If the driver does not stop the vehicle
within 10 metres after a parking slot is
proposed, the system starts to search
for another suitable parking slot.
