ACTIVE SAFETY SYSTEMS
ABS SYSTEM
33) 34) 35) 36) 37) 38) 39)
This system, which is an integral part of
the braking system, prevents one or more
wheels from locking and slipping in all
road surface conditions, irrespective of
the intensity of the braking action,
ensuring that the vehicle can be
controlled even during emergency
braking and optimising stopping
distances.
System intervention
The driver can feel that the ABS system
has come into action because the brake
pedal pulsates slightly and the system
gets noisier: this is entirely normal with
the system operating.
ASR (AntiSlip Regulation) SYSTEM
40) 41) 42)
This is an integral part of the ESC system
and automatically operates in the event
of one or both drive wheels slipping, loss
of grip on wet roads (aquaplaning) and
acceleration on slippery, snowy or icy
roads, etc.
System intervention
The system operates on the engine
power and brakes.
This is indicated by the flashing of the
warning light
on the instrument panel,
to inform the driver that the car is in
critical stability and grip conditions.
BRAKE ASSIST SYSTEM (assistance
during emergency braking)
The system, which cannot be turned off,
recognises emergency braking (on the
basis of the brake pedal operating speed)
and speeding up the response of the
braking system.The Brake Assist device
is deactivated if there is a ESC system
failure.
MSR (Motor Schleppmoment
Regelung) SYSTEM
The system prevents the drive wheels
from possibly locking, which could
happen, for example, if the accelerator
pedal is released suddenly or in the case
of a sudden downshifting in conditions of
poor grip.
In this conditions, the engine braking
effect could cause the drive wheels to
slip, resulting in a loss of vehicle stability.
In these situations, the system
intervenes, restoring torque to the
engine in order to conserve vehicle
stability and increase vehicle safety.
DST SYSTEM (Dynamic Steering
Torque)
46)
This function integrates Dual Pinion
active steering into the operation of ESC.
For particular manoeuvres, the ESC
system controls the steering to actuate a
steering torque and assist the driver in
the best possible way.
The system operates the brakes and
steering in a coordinated manner to
increase the suspension and safety level
of the car as a whole.The steering
provides additional torque on the
steering wheel.
EBD SYSTEM
The EBD system is an integral part of the
ESC system and intervenes during
braking, distributing the brake force
optimally between front and rear wheels.
This guarantees greater braking stability
for the car, preventing sudden locking of
the rear wheels and the consequent
instability of the car.
ESC SYSTEM
28) 29) 30) 31) 32)
The ESC system improves the directional
control and stability of the car in various
driving conditions.
66
SAFETY
The ESC system corrects the car’s
understeer and oversteer, distributing
the brake force on the appropriate
wheels.The torque supplied by the
engine can also be reduced in order to
maintain control of the vehicle.
The ESC system comprises the active
safety systems such as: ABS, EBD, ASR,
HILL HOLDER, BRAKE ASSIST, MSR,
CBC, “ELECTRONIC Q2”, DST.
The ESC system switches on
automatically when the engine is started
and cannot be switched off.
System intervention
This is indicated by the flashing of the
warning light
on the instrument panel,
to inform the driver that the car is in
critical stability and grip conditions.
CBC (Cornering Brake Control) SYSTEM
This system acts when braking on
corners, optimising the distribution of
brake pressure on the four wheels: the
system prevents the wheels on the inside
of the corner (less affected by the weight
of the car) from locking, ensuring better
stability and direction for the car.
HILL HOLDER SYSTEM
This is an integral part of the ESC system
and facilitates starting on uphill or
downhill slopes by operating the brakes:
IMPORTANTThe Hill Holder system is
not a parking brake; therefore, never
leave the car without having engaged the
handbrake, turned the engine off and
engaged first gear, so that it is parked in
safe conditions (for further information
read the "Parking" paragraph in the
"Starting and driving" chapter).
IMPORTANTThere may be situations on
small gradients (less than 5%), with car
laden, in which the Hill Holder system
may not activate, causing a slight
reversing motion and increasing the risk
of collision with another vehicle or object.
The driver is, in any case, responsible for
safe driving.
“ELECTRONIC Q2” SYSTEM (“E-Q2”)
The "Electronic Q2" system intervenes
during acceleration on corners, braking
the inner drive wheel and thus increasing
the traction of the outer wheel (which
bears more of the car’s weight): the
torque is thus distributed optimally
between the drive wheels in accordance
with the driving conditions and road
surface, permitting particularly effective,
sporty driving.
WARNING
28)
The ESC system cannot alter the natural
laws of physics, and cannot increase grip,
which depends on the condition of the road.
29)
The ESC system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
30)
The capability of the ESC system must
never be tested irresponsibly and
dangerously, in such a way as to compromise
personal safety and the safety of others.
31)
For the correct operation of the ASR
system, the tyres must of necessity be the
same make and type on all wheels, in perfect
condition and, above all, of the prescribed
type and dimensions.
32)
Do not take unnecessary risks, even if
your vehicle is fitted with the ESC and ASR
systems. Your driving style must always be
suited to the road conditions, visibility and
traffic. The driver is always responsible for
road safety.
33)
When the ABS intervenes and you feel
the brake pedal pulsating, do not reduce the
pressure, but hold it down firmly and
confidently; in doing so you will brake in the
shortest distance possible, depending on the
current road conditions.
34)
To obtain the maximum efficiency of the
braking system, a bedding-in period of about
500 km is needed: during this period it is
better to avoid sharp, repeated and
prolonged braking.
35)
If the ABS intervenes, this indicates that
the grip of the tyres on the road is nearing its
limit: you must slow down to a speed
compatible with the available grip.
67
36)
The ABS cannot overrule the natural
laws of physics, and cannot increase the grip
available according to the condition of the
road.
37)
The ABS cannot prevent accidents,
including those due to excessive speed on
corners, driving on low-grip surfaces or
aquaplaning.
38)
The capability of the ABS must never be
tested irresponsibly and dangerously, in
such a way as to compromise personal
safety and the safety of others.
39)
For the correct operation of the ABS, the
tyres must of necessity be the same make
and type on all wheels, in perfect condition
and, above all, of the prescribed type and
dimensions.
40)
The ASR cannot overrule the natural
laws of physics, and cannot increase the grip
available according to the condition of the
road.
41)
The ASR system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
42)
The capability of the ASR must never be
tested irresponsibly and dangerously, in
such a way as to compromise personal
safety and the safety of others.
43)
The HBA system can’t overrule the
natural laws of physics, and can’t increase
the grip available according to the condition
of the road.
44)
The HBA system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
45)
The features of the HBA system must
never be tested in imprudent or dangerous
ways, with the possibility of putting the
safety of the driver, occupants or other road
users at risk.
46)
DST is an aid for driving and does not
relieve the driver of responsibility for driving
the vehicle.
TPMS (Tyre Pressure
Monitoring System)
(where provided)
47) 48) 49) 50) 51) 52) 53) 54) 55)
DESCRIPTION
The vehicle can be equipped with the tyre
pressure monitoring systemT.P.M.S.
which informs the driver about the tyre
inflating condition through viewing on the
display specific warning messages.
This system comprises a radio frequency
transmitter fitted to each wheel (on the
wheel rim inside the tyre), which is able to
send information on the tyre inflation
pressure of each wheel to the control
unit.
IMPORTANT NOTES ABOUTTHE TPMS
The fault indications are not stored and
will therefore not be displayed after the
engine has been switched off and then on
again.
If the fault conditions persist, the control
unit will send the relative indications to
the instrument panel only after the car
has been in motion for a short time.
