FOUR WHEEL DRIVE SYSTEM
WITH ELECTRONIC CONTROL
4WD AUTO (position 1)
The vehicle operates with four wheel
drive and provides optimum traction re-
gardless of the level 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
guaranteeing optimum road holding.
Three transmission modes are avail-
able and can be selected manually
by the driver in accordance with his
requirements.
You can change transmission mode
when stationary or while driving at a
speed below 60 mph (100 km/h) .
The transmission mode can be selected
by turning the control A .
Display on the instrument panel
The transmission mode is displayed in
the form of an intermittent display on
the instrument panel screen when the
transmission mode is selected.
Selecting the transmission mode
The selection of this mode is recom-
mended when the level of grip permits.
2WD (position 3)
The vehicle operates with front two
wheel drive.
This mode corresponds to use on a
tarmacked road on which the driver
considers that there is no risk of loss of
grip (dry road).
4WD LOCK (position 2)
The vehicle operates with four wheel
drive in this mode also.
It is recommended when grip is particularly
p o o r o r d i f fi c u l t ( s a n d , m u d , s l o p e s , . . . ) .
System which permits the selection of
a transmission mode in relation to the
driving conditions.
