ABS
This is an integral part of the braking
system, which prevents one or more
wheels from locking or slipping
regardless of the road surface
conditions and braking intensity,
ensuring control of the vehicle even
during emergency braking.
The system intervenes when braking
and the wheels are about to lock,
typically in emergency braking or
low-grip conditions, when locking may
be more frequent.
The ABS ensures the direction of the
vehicle while braking and optimises the
braking distances at the same time.
The system also improves control and
stability of the car when braking on a
surface where the grip of the left and
right wheels varies, or when braking on
corners.
The system is completed by EBD
(Electronic Braking Force Distribution),
which distributes the braking action
between the front and rear wheels.
IMPORTANT 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.
50)
SYSTEM INTERVENTION
The driver can feel that the ABS has
come into action because the brake
pedal pulsates slightly and the system
gets noisier: it means that the car
speed should be altered to suit the type
of road surface.
51) 52) 52) 53) 54) 55) 56) 57)
MSR SYSTEM
(Motor Schleppmoment Regelung)
This system is an integral part of the
ABS and intervenes, if there is sudden
downshifting, restoring torque to the
engine, thereby preventing excessive
drive at the drive wheels which,
especially in poor grip conditions, could
lead to a loss in stability of the vehicle.
WARNING
50) The ABS exploits the grip
available to the full, but it cannot
improve it. Therefore, you should
take great care when driving on
slippery surfaces, without taking
unnecessary risks.51) When the ABS intervenes and
you notice the brake pedal
pulsating, keep the pedal pushed
down and don’t be alarmed. This
will help you to stop in the
shortest distance possible,
depending on the road conditions.
52) If the ABS intervenes, it means
you have almost reached the grip
limit between the tyres and the
road surface: slow down to make
sure that you drive in accordance
with the available grip
53) The ABS can’t overrule the
natural laws of physics, and can’t
increase the grip available
according to the condition of the
road.
54) The ABS cannot prevent
accidents, including those due to
excessive speed on corners,
driving on low-grip surfaces or
aquaplaning.
55) 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.
56) For the correct operation of the
ABS, it is essential that the tyres
are of the same make and type on
all wheels, in perfect condition
and, above all, of the specified
type and dimensions.
81
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
After reaching the desired speed,
release the accelerator and brake
pedals completely (the LED on the
button flashes). If you want to
increase/decrease the speed, press the
accelerator/brake pedals again.
IMPORTANT Do not use the device
with the gearbox in neutral position.
IMPORTANT It is important to engage a
gear suitable for the set speed, to
prevent the engine from stalling.
When this function is active the brake
lights turn on automatically.
While the HDC system is operating it is
also possible to take control of the
vehicle again by pressing the brake and
accelerator pedals.
If the function is not made available
when the button is pressed, this could
be due to brake overheating. In this
case, wait a few minutes before using
the function again.
IMPORTANT The system is available for
speeds below 25 km/h.IMPORTANT Above 25 km/h the HDC
system deactivates but is still ready
to operate (the LED on the button
remains on) when the speed is again
below 25 km/h. If the speed exceeds
50 km/h, the HDC system deactivates
completely (the LED on the button
switches off) and the function does not
operate autonomously on the brakes
anymore. To reactivate it, press the
dedicated button again when the speed
is again below 25 km/h.
8)
WARNING
58) The ESC system can’t overrule
the natural laws of physics, and
can’t increase the grip available
according to the condition of
the road.
59) The ESC system cannot prevent
accidents, including those due to
excessive speed on corners,
driving on low-grip surfaces or
aquaplaning.60) 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.
61) The performance of the ESC and
ASR systems must not encourage
the driver to take unnecessary
risks. Driving style must always be
adapted to road conditions,
visibility and traffic. The driver is,
in any case, responsible for safe
driving.
62) For the ESC and ASR systems to
function correctly, all four tyres
must be the same brand and type,
must be in excellent condition
and, above all, must be of the
prescribed type and size.
63) The HBA system cannot increase
tyre grip on the road over the
limits imposed by laws of physics:
always drive carefully according
to the conditions of the road
surface.
64) The HBA system cannot prevent
accidents, including those due to
excessive speed on bends,
travelling on low-grip surfaces or
aquaplaning.
85
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
SYSTEM ACTIVATION/
DEACTIVATION
When the system is active, if the vehicle
gets close to one of the limit lines or
one of the two lane demarcation lines,
the driver is warned with an acoustic
signal (coming from the crossed line
side if the vehicle is equipped with the
radio navigation system) along with
the corresponding direction warning
light (
or) lighting up.
If the driver turns on the direction
indicator in order to change lanes or for
overtaking, then the system will switch
off the driver warning.
If the driver keeps deliberately with the
lane change manoeuvre, the system
interrupts the warning, remaining
enabled if the operating conditions are
not satisfied or active if the operating
conditions are exceeded (see the
dedicated paragraph).SWITCHING OFF THE
SYSTEM
Manual mode
The system can be switched off by
pressing button A fig. 128 on the
dashboard.
The LED on the button switches on and
a message appears on the display to
confirm that the system has been
switched off.
Automatic mode
If the Start&Stop is active the system
deactivates automatically. The system
will reactivate and check its operating
conditions again after the vehicle has
been started.
SYSTEM FAILURE
In the case of malfunction the system
signals the fault to the driver with a
message on the display, an acoustic
warning and switching on of the icon
on the display (for versions/markets,
where provided).IMPORTANT INFORMATION
The Driving Advisor cannot operate due
to a not perfectly balanced and
excessive load.
The operation of the system can be
adversely affected in some cases
by the morphology of the territory/road
being driven on (e.g. driving over
humps), poor visibility conditions (e.g.
fog, rain, snow), extreme light
conditions (e.g. glare of the sun,
darkness), lack of cleanliness
or damage, even partial, to the
windscreen in the area in front of the
camera.
The Driving Advisor cannot operate
following a malfunction of the following
safety systems: ABS, ESP, ASR and
Traction Plus.
The operation of the system can be
adversely affected by poor visibility
conditions (e.g. fog, rain, snow),
extreme light conditions (glare of the
sun, darkness), lack of cleaning or
damage, even partial, to the
windscreen in the area in front the
camera.
The area of the windscreen by the
camera must not be partly or totally
obscured by objects (e.g. stickers,
protective film, etc.).
92
KNOW YOUR VEHICLE
WARNING
78) If the camera loses its position
due to a load variation, the system
may not work temporarily to allow
the camera to perform an
autocalibration.
79) The Driving Advisor is not an
automatic driving system and
does not replace the driver in
controlling the trajectory of the
car. The driver is personally
responsible for maintaining a
sufficient level of attention to the
traffic and road conditions and
for controlling the trajectory of the
car safely.
80) In the case of indistinct,
overlapping or missing lane
demarcation lines, the system
may not assist the driver: in this
case the Driving Advisor will be
inactive.
