SAFETY

of putting the safety of the driver or other
people at risk.
IMPORTANT
26)
Prolonged use of the system may
overheat the braking system. If the brakes
overheat, the HDC system, when active,
will be gradually deactivated after suitably
informing the driver (the LED on the button
turns off): it can be reactivated only when
the brakes have cooled sufficiently. The
distance you can travel depends on the
brake temperature and thus on the slope,
the load and the vehicle speed.
TRACTION PLUS
SYSTEM
(for versions/markets, where provided)
Traction Plus is a driving aid,
useful for setting off in poor grip
conditions on non-homogeneous road
surfaces (snow/asphalt, ice/asphalt,
mud/asphalt, etc.), which allows the
drive force to be distributed adequately
on the engine axle when one of the two
drive wheels slips.
Traction Plus acts by braking the
wheel with poor grip (or the one which
slips more than the others), thereby
transferring the drive force to those
which have greater grip on the ground.
This function can be turned on
manually by pressing the (A) button
fig. 164 on the dashboard and works
below a level of 50 km/h. Over this
speed, it is automatically deactivated
(the LED on the button is still on) and it
is reactivated again when the speed is
below 30 km/h.

TRACTION PLUS OPERATION
When the engine is started the system
is disabled.
To activate the "Traction Plus" system,
press the button (A) fig. 164: the LED
on the button switches on.
164 F1A0645
The activation of the Traction Plus
system involves the following functions
being switched on:
inhibition of the ASR function, in
order to fully exploit the engine torque;
the differential locking effect on
the front axle, through the braking
system, to improve traction on irregular
grounds.
If the "Traction Plus" system is faulty,
the "general failure" instrument panel
warning light comes on steady.
When travelling on snowy roads with
snow chains, it may be helpful to turn
the Traction Plus on and thus inhibiting
the ASR function: in fact, in these
conditions, slipping of the drive wheels
when moving off makes it possible to
obtain better traction.
WARNING
74)
The Traction Plus system acts
effectively only on road surfaces that are
not homogeneous and/or differentiated
between the two drive wheels.
75)
Until the setting off manoeuvre is
terminated, fully depress the accelerator
pedal in order to transfer all the drive
torque to the wheel with the best grip.
