Four wheel drive system
System which permits the selection of a transmission mode in relation to the driving conditions.
Three transmission modes are available and can be selected manually by the driver in accordance with his requirements.
You can change transmission mode when
stationary or while driving.
The transmission mode can be selected by
turning the control A.
Selecting the transmission
mode
4WD AUTO (position 1)
The vehicle operates with four wheel drive and
provides optimum traction for all levels of grip.
This is the vehicle's normal and regular
operating mode, the distribution of the torque
between the front and rear axles is controlled
automatically.
The distribution favours the front wheels,
the transfer of torque to the rear wheels is
managed electronically by the control unit
in relation to the level of grip, so providing
optimum road holding.
4WD LOCK (position 2)
The vehicle operates with four wheel drive in
this mode also.
It is recommended when grip is particularly
poor or difficult (sand, mud, slopes, ...).
2WD (position 3)
The vehicle operates with front two wheel drive.
This is suitable for use on a tarmac roads or
where the driver considers that there is no risk
of loss of grip (dry road).
Display in the instrument panel
The transmission mode is displayed in the
form of an intermittent display in the instrument
panel screen when the transmission mode is
selected.The selection of this mode is
recommended when the level of grip
permits.

Associated systems which guarantee the directional stability of the vehicle within the limits of the laws of physics:
- t raction control (TCL),
-

a
ctive stability control (ASC).
Traction control and active stability control
Traction control optimises traction to prevent
wheel spin, by acting on the brakes of the
driving wheels and on the engine.
Active stability control acts on the brake of one
or more wheels and on the engine to keep the
vehicle on the trajectory required by the driver.Activation
These systems are activated automatically
each time the vehicle is started.
The illumination of this warning lamp
in the instrument panel indicates
that the ASC and TCL systems are
deactivated.
Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, ...), it may be advisable to deactivate
the ASC system, so that the wheels can move
freely and regain grip.
This is indicated by flashing of this
symbol on the instrument panel
screen.
Trajectory control systems
F Press this button, located to the right of the steering wheel, until the symbol appears in
the instrument panel screen.
Operation
They operate when the vehicle speed is higher
than 10 mph (15 km/h).
They come into operation in the event of a grip
or trajectory problem.
