57) If the space-saver wheel (for
versions/markets, where
provided) is used, the ABS keeps
operating. Always remember
that the space-saver wheel, being
smaller than the original wheel,
provides less grip.ESC (Electronic
Stability Control)
SYSTEM
(for versions/markets, where provided)
The ESC system improves the
directional control and stability of the
vehicle in various driving conditions.
The ESC system corrects the vehicle’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 uses the sensors in
the vehicle to determine the trajectory
required by the driver through steering
and compares it with the real trajectory
of the vehicle. When the real trajectory
deviates from the desired trajectory, the
ESC system intervenes to counter the
car’s understeer or oversteer.
❒Oversteer: occurs when the vehicle is
turning more than it should according
to the angle of the steering wheel.
❒Understeer: occurs when the vehicle
is turning less than it should
according to the angle of the steering
wheelThe ESC system also includes the
following subsystems:
❒Hill Holder
❒ASR
❒HBA
❒ERM
❒HDC
58) 59) 60)
SYSTEM INTERVENTION
This is signalled by the flashing of
warning light
in the instrument panel,
to inform the driver that the vehicle is
in critical stability and grip conditions.
SYSTEM ACTIVATION
The ESC system switches on
automatically when the engine is
started and cannot be switched off.
82
KNOW YOUR VEHICLE
HILL HOLDER SYSTEM
This system is an integral part of the
ESC system and facilitates starting on
slopes.
It is automatically activated in the
following conditions:
❒uphill: vehicle stationary on a road
with a gradient higher than 5%,
engine running, brake pressed and
gearbox in neutral or gear (other than
reverse) engaged;
❒downhill: vehicle stationary on a road
with a gradient higher than 5%,
engine running, brake pressed and
reverse gear engaged.
When setting off, the ESC system
control unit maintains the braking
pressure on the wheels until the torque
necessary for starting is reached, or
in any case for a maximum of 2
seconds, allowing your right foot to be
moved easily from the brake pedal to
the accelerator.
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.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 first gear,
so that it is parked in safe conditions
(for further information read the
"Parking" paragraph in the "Starting
and driving" chapter).
ASR (AntiSlip
Regulation) SYSTEM
It is an integral part of the ESC system.
It 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.
Depending on the slipping conditions,
two different control systems are
activated:
❒if the slipping involves both drive
wheels, the ASR 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.
62)
Engagement/ disengagement of the
ASR system
The ASR system switches on
automatically each time the engine is
started.
Whilst driving, the ASR can be switched
off and subsequently switched on
again by pressing the ASR OFF button
fig. 125.
61)
On some versions, the intervention of
the system is indicated by a message
shown on the display.
When the system is not active, the LED
on the button ASR OFF turns on and,
on some versions, a message appears
on the display.
If the ASR is disengaged during driving,
it is automatically reactivated when
the vehicle is next started.
125F1A0324
83
When travelling on snowy roads with
snow chains, it may be helpful to turn
the ASR off: in fact, in these conditions,
the driving wheels slipping when
moving off gives you better traction.
HBA SYSTEM
(Hydraulic Brake Assist)
The HBA system is designed to
improve the vehicle’s braking capacity
during emergency braking. The system
detects emergency braking by
monitoring the speed and strength with
which the brake pedal is pressed,
thereby applying the optimal brake
pressure.
This can reduce the braking distance:
the HBA system therefore completes
the ABS.
Maximum assistance from the HBA
system is obtained by pressing the
brake pedal very quickly. In addition,
the brake pedal must be pressed
continuously during braking, avoiding
intermittent presses, to benefit from the
system.
Do not reduce pressure on the brake
pedal until braking is not necessary
anymore.
The HBA system is deactivated when
the brake pedal is released.
63) 64) 65)
ERM ELECTRONIC ROLLOVER
MITIGATION SYSTEM
(Electronic Rollover Mitigation)
The system monitors the tendency of
the wheels to rise from the ground if the
driver performs extreme manoeuvres
like quick steering to avoid an obstacle,
especially in poor road conditions.
If these conditions occur, the system
intervenes on the brakes and engine
power to reduce the possibility that the
wheels are raised from the ground.
It is not possible to avoid the tendency
to roll over if this is due to reasons
such as driving on high side gradients,
collision with objects or other vehicles.
66)
HILL DESCENT CONTROL
(HDC) SYSTEM
It is an integral part of the ESC and is
aimed at keeping the vehicle at a
constant speed during a descent,
operating autonomously on the brakes
in various ways at the same time. In this
way the vehicle stability and completely
safe driving are guaranteed, above all
in poor grip conditions and/or steep
descents.
To activate the system reach a speed
slower than 25 km/h and press the
dedicated key A fig. 126; the LED on
the button turns on and the display
gives a specific message.
126F1A0300
84
KNOW YOUR VEHICLE
65) The HBA system is an aid for the
driver, who must always pay full
attention while driving. The
responsibility always rests with
the driver. 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.
66) The performance of a vehicle
with ERM must never be tested
in imprudent or dangerous ways,
with the possibility of putting
the safety of the driver or other
people at risk.
IMPORTANT
8) 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 that can be covered
depends on the temperature of
the brakes and therefore on the
gradient, load and speed of the
vehicle.
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 slipping more than
the others), thereby transferring the
drive force to that which has greater
grip on the ground.
This function can be activated manually
by pressing button A on the dashboard
fig. 127 and operates under 50 km/h.
When this speed is exceeded, it is
automatically deactivated (the LED on
the button is still on) and it is
reactivated again when the speed falls
below 30 km/h.
67) 68)
86
KNOW YOUR VEHICLE
Traction Plus operation
The system is deactivated when
starting. To activate the Traction Plus
system, press button A fig. 127: 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
warning light on the instrument
panel switches on constantly.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
67) The Traction Plus system acts
effectively only on road surfaces
that are not homogeneous and/or
differentiated between the two
drive wheels.
68) 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.
TPMS (Tyre
Pressure
Monitoring System)
(for versions/markets, where provided)
69) 70) 71) 72) 73) 74) 75) 76) 77)
DESCRIPTION
The tyre pressure monitoring system
(TPMS) warns the driver of low tyre
pressure on the basis of the cold
inflation pressure prescribed for the
vehicle.
Changes in outside temperature may
cause tyre pressure to vary. This means
that a decrease in the outside
temperature corresponds to a decrease
in the tyre pressure.
Tyre pressure must always be adjusted
according to the cold inflation pressure.
Cold tyre inflation pressure is the tyre
pressure after letting the vehicle stand
for at least three hours or a travel
shorter than 1.6 km after an interval of
three hours.
The cold tyre inflation pressure must
not exceed the maximum inflation
pressure value printed on the side of
the tyre.
127F1A0325
87
The tyre pressure also increases while
driving the vehicle: this is a normal
condition and does not require any
adjustment of the pressure.
The TPMS continues to advise the
driver of the low tyre pressure condition
until this is corrected; the warning
continues until the pressure
corresponds or exceeds the pressure
prescribed for the cold tyres. When the
tyre low pressure control warning
light
switches on constantly, the
inflation pressure must be adjusted until
it reaches the pressure prescribed for
cold tyres. After the automatic update
of the system, the tyre pressure control
warning light switches off. You may
need to drive the vehicle for about 20
minutes at a speed higher than 20
km/h to allow the TPMS to receive this
information.
NOTE
❒The TPMS does not replace the
normal tyre maintenance service and
does not indicate any fault in a tyre.
❒Therefore, the TPMS should not be
used as pressure switch while
adjusting the tyre inflation pressure.❒Driving with insufficient tyre pressure
causes their overheating and can
result in tyre failure. The low inflation
pressure reduces fuel efficiency
and tyre tread life and may also affect
handling and braking performance
of the vehicle.
❒The TPMS does not replace the
correct tyre maintenance. It is up to
the driver to maintain the correct tyre
pressure level measuring it with a
suitable pressure switch. This is
necessary even if the decrease in the
inflation pressure value does not
cause the tyre pressure control
warning light to switch on.
❒The TPMS warns the driver of any
condition of insufficient tyre pressure
If this drops below the insufficient
pressure limit for any reason including
low temperature and normal
pressure loss of the tyre.
❒The seasonal temperature changes
affect tyre pressure.
The TPMS uses wireless devices with
electronic sensors mounted on the
wheel rims to constantly monitor the
value of tyre pressure. The sensors
mounted on each wheel as part of the
valve stem transmit various information
of the tyres to the receiver module, in
order to calculate the pressure.WARNING Monitoring and maintaining
the correct pressure in all four tyres
are particularly important.
Tyre pressure
monitoring system low
pressure warnings
The system warns the driver if one or
more tyres are flat by switching on
the warning light
on the instrument
panel (together with a warning message
and an acoustic signal).
In this case, stop the vehicle as soon as
possible, check the inflation pressure
of each tyre and inflate to the cold tyre
pressure value prescribed for the
vehicle. The system will automatically
update and after receiving the tyre
pressure update the tyre pressure
control warning light switches off. You
may need to drive the vehicle for about
20 minutes at a speed higher than 20
km/h to allow the system to receive this
information.
88
KNOW YOUR VEHICLE
TPMS operation faults
The system fault is indicated by
warning light
which first flashes for
75 seconds and then stays on steadily.
This can occur in any of the following
situations:
❒interference caused by electronic
devices or radio frequency emissions
similar to those of the TPM sensors.
❒Application of tinted films which
interfere with the signals of the radio
waves.
❒Presence of snow or ice on the
wheels or the wheel arches.
❒Use of snow chains.
❒Use of wheels/tyres not equipped
with TPM sensors.
❒The space-saver wheel is not
equipped with the tyre pressure
control sensor. Therefore, the tyre
pressure is not controlled by the
system.
❒If the space-saver wheel replaces a
tyre with a pressure lower than the
insufficient pressure limit, an acoustic
signal will be emitted and the warning
light
will switch on at the next
ignition cycle.❒When the original tyre is repaired or
replaced and it is mounted back on
the vehicle to replace the space-
saver wheel, the TPMS will update
automatically and the warning light
will switch off, provided that the
pressure of none of the four tyres is
below the insufficient pressure limit.
You may need to drive the vehicle for
about 20 minutes at a speed higher
than 20 km/h to allow the TPMS
to receive this information.IMPORTANT
INFORMATION
WARNING
69) The TPMS is optimised for the
original tyres and wheels
provided. TPMS pressures and
alerts have been defined
according to the size of the tyres
mounted on the vehicle. Using
equipment with different size,
type or kind may cause irregular
system operation or sensor
damage. Non-original spare
wheels can damage the sensor.
Do not use tyre sealant or
balancing weights if the vehicle is
equipped with TPMS as these
may damage the sensors.
70) If the system signals a pressure
decrease on a specific tyre, it is
recommended to check the
pressure on all four tyres.
71) TPMS does not relieve the driver
from the obligation to check the
tyre pressure every month; it is
not even to be considered a
replacing system for maintenance
or a safety system.
