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.
61)
Engagement/ disengagement of the
ASR system
The ASR is switched on automatically
each time the engine is started.
While driving, the ASR can be switched
off and subsequently switched on
again by pressing the ASR OFF button
(A fig. 101).
62)
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.
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 skidding 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 an 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 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 no longer
necessary.
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.

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.
The tyre pressure also increases while
driving the vehicle: this is a normal
condition and does not require any
adjustment of the pressure.

SAFETY

Presence of snow or ice on the
wheels or the wheel arches.
Use of snow chains.
Use of wheels/tyres not equipped
with TPMS 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 turn on at the next
start-up.
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.
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)The 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.
72)Tyre pressure must be checked with
tyres cold. Should it become necessary for
whatever reason to check pressure with
warm tyres, do not reduce pressure even
though it is higher than the prescribed
value, but repeat the check when tyres are
cold.
73)The TPMS cannot indicate sudden tyre
pressure drops (for example when a tyre
bursts). In this case, stop the vehicle,
braking with caution and avoiding abrupt
steering.74)The system only warns that the tyre
pressure is low: it is not able to inflate
them.
75)Insufficient tyre inflation increases fuel
consumption, reduces the tread duration
and may affect your ability to drive the
vehicle safely.
76)Always refit the valve stem cap after
inspecting or adjusting tyre pressure. This
prevents dampness or dirt from entering
the valve stem and thus the pressure
control sensor from being damaged.
77)The tyre repair kit (Fix&Go) provided
with the vehicle (for versions/markets,
where provided) is compatible with the
TPMS sensors; using sealants not
equivalent with that in the original kit may
adversely affect its operation. If sealants
not equivalent with the original ones are
used, it is recommended to have the
TPMS sensor operation checked by a
qualified repair centre.

SNOW TYRES
The performance of these tyres is
considerably reduced when the tread
depth is less than 4 mm. Replace them
in this case.
IMPORTANT When using snow tyres
with a maximum speed index below the
one that can be reached by the vehicle
(increased by 5%), place a notice in
the passenger compartment, plainly in
view, which states the maximum speed
allowed by the snow tyres (as per EC
Directive).
All four tyres should be the same (brand
and track) to ensure greater safety
when driving and braking as well as a
good manoeuvrability.
Remember that you should not change
the rotation direction of the tyres.
204)
WARNING
204)The maximum speed for snow tyres
marked “Q” is 160 km/h, while it is 190
km/h for “T” tyres and 210 km/h for "H"
tyres. You should, however, always stick to
the speed limits of the highway code.
SNOW CHAINS
The use of snow chains should be in
compliance with local regulations of
each country.
Snow chains can be fitted to the tyres
of the front wheels (drive wheels) only.
Use of Lineaccessori MOPAR snow
chains is recommended. Check the
tension of the snow chains after the first
few metres have been driven.
58)
IMPORTANT With snow chains, use the
accelerator with extreme care to
prevent, or to limit as much as possible,
slipping of the drive wheels that could
cause chain breakage, resulting in
damage to the car body or mechanical
components.
IMPORTANT For versions fitted with
225/75 R16 tyre, use snow chains with
max. thickness 16 mm.
When travelling on snowy roads with
snow chains, it may be helpful to turn
the ASR off: in fact, in these conditions,
the drive wheels skidding when setting
off gives you better traction.
WARNING
58)Keep the vehicle's speed down when
snow chains are fitted; never exceed 50
km/h. Avoid potholes, do not drive over
steps or pavements, and do not drive long
distances over roads without snow, to
avoid damaging both your vehicle and the
road surface.
