HILL HOLDER SYSTEM
(for versions/markets, where provided)
It's integral to the ESP system. It automatically
activates with the following conditions:
❒uphill: vehicle stationary on a road with a gradient
higher than 5%, engine running, brake pedal
pressed and gearbox in neutral or gear other than
reverse;
❒downhill: vehicle stationary on a road with a
gradient higher than 5%, engine running, brake
pedal pressed and reverse gear engaged.
At pickup, the ESP system control unit will keep
braking pressure on the wheels until reaching the
required torque for starting or, in any case, for
a maximum of 2 seconds in order to move easily the
right foot from the brake pedal to the accelerator
pedal. When two seconds have elapsed, without
starting, the system is automatically deactivated,
gradually releasing the braking pressure. During this
release stage, the typical brake disengagement noise
indicating that the vehicle is going to move
imminently will be heard.Failure indications
IMPORTANT The Hill Holder system is not a parking
brake; therefore, never leave the vehicle without
having engaged the handbrake, turned the engine off
and engaged the first gear.
WARNING
For the correct operation of the ESP and
ASR systems, the tyres must be the
same make and type on all wheels, in perfect
condition and, above all, of the type, make and
size recommended.

ASR SYSTEM (Anti-Slip Regulation)
(for versions/markets, where provided)
This is a traction control system that cuts in
automatically every time one or both drive wheels
slip.
Depending on how slippery the road is, two different
control systems are activated:
❒if slipping involves both driving wheels, the ASR
function intervenes reducing the power
transmitted by the engine;
❒if the slipping only involves one of the drive
wheels, it intervenes automatically braking the
wheel that is slipping.
The action of the ASR system is especially useful in
the following conditions:
❒slipping of the inner wheel round bends due to
dynamic variations in the load of excessive
acceleration;
❒excessive power transmitted to the wheels, also in
relation to road surface conditions;
❒acceleration on slippery, snowy or icy road
surfaces;
❒in the case of loss of grip on a wet surface
(aquaplaning).
WARNING
For the correct operation of the ESP and
ASR systems, the tyres must be the
same make and type on all wheels, in perfect
condition and, above all, of the type, make and
size recommended.
MSR SYSTEM (engine drive regulation)
This is an integral part of the ASR system that, in the
event of a sudden gear down shift, cuts in and
provides torque to the engine thus preventing
excessive drive wheel drive which, especially in poor
grip conditions, can lead to a loss of stability.

TRACTION PLUS SYSTEM(for versions/markets, where provided)
Traction Plus is a help with driving and setting off in
poor grip conditions (snow, ice, mud, etc.) which
allows the drive force to be evenly distributed over
the same axle when both wheels are slipping.
In effect, Traction Plus acts by braking the wheels
with poor grip (or those slipping more than the
others), thereby transferring the drive force to those
which have more grip on the ground.
This function can be turned on manually by pressing
the T+ button fig. 92 on the dashboard and works
below a level of 30 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
The system is deactivated when starting up. To
activate the "Traction Plus" system, press the button
(T+ fig. 92): the LED on the button switches on.
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.
