SAFETY
This very important section describes the safety
systems that your vehicle may be equipped with,
and provides instructions on how to use them
correctly.
ACTIVE SAFETY SYSTEMS
The vehicle may be equipped with the following
active safety devices:
Anti-Lock Brake System (ABS)
Active Torque Vectoring (ATV) System
Dynamic Steering Torque (DST) System
Drive Train Control (DTC) System
Electronic Stability Control (ESC) System
Hill Descent Control (HDC) System
Hill Start Assist (HSA) System
Panic Brake Assist (PBA) System
Traction Control System (TCS)
For system operation, see the following pages.
ANTI-LOCK BRAKE SYSTEM (ABS)
An integral part of the braking system, the ABS
prevents one or more wheels from locking and
slipping in all road surface conditions, regardless
of the intensity of the braking action. The system
ensures that the vehicle can be controlled even
during emergency braking, allowing the driver to
optimize stopping distances.
The system intervenes during braking when the
wheels are about to lock, typically in emergency
braking or low-grip conditions where locking may
be more frequent. The system also improves control and stability of
the vehicle when braking on a surface where the
grip of the left and right wheels varies, such as in
a corner.
The Electronic Braking Force Distribution (EBD)
system works with the ABS, allowing the brake
force to be distributed between the front and rear
wheels.
System Intervention
The ABS equipped on this vehicle is provided with
the "Brake-By-Wire", Integrated Brake System
(IBS), function. With this system, the command
given by pressing the brake pedal is not
transmitted hydraulically, but electrically.
Therefore, the light pulsation that is felt on the
pedal with the traditional system is no longer
noticeable.
ACTIVE TORQUE VECTORING (ATV)
S
YSTEM — IF EQUIPPED
The dynamic drive control is used to optimize and
balance the drive torque between the wheels of
the same axles. The ATV system improves the grip
in turns, sending more drive torque to the
external wheel.
Given that, in a turn, the external wheels of the
car travel more than the internal ones and
therefore turn faster, sending a higher thrust to
the external rear wheel allows for the car to be
more stable and to not suffer an "understeer"
condition. Understeer occurs when the vehicle is
turning less than appropriate for the steering
wheel position.
WARNING!
The ABS contains sophisticated electronic
equipment that may be susceptible to
interference caused by improperly installed
or high output radio transmitting equipment.
This interference can cause possible loss of
anti-lock braking capability. Installation of
such equipment should be performed by
qualified professionals.
Pumping of the Anti-Lock Brakes will
diminish their effectiveness and may lead to
a collision. Pumping makes the stopping
distance longer. Just press firmly on your
brake pedal when you need to slow down or
stop.
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can it
increase braking or steering efficiency
beyond that afforded by the condition of the
vehicle brakes and tires or the traction
afforded.
The ABS cannot prevent collisions, including
those resulting from excessive speed in
turns, following another vehicle too closely,
or hydroplaning.
The capabilities of an ABS equipped vehicle
must never be exploited in a reckless or
dangerous manner that could jeopardize the
user’s safety or the safety of others.

DYNAMIC STEERING TORQUE (DST)
S
YSTEM
DST uses the integration of the Electronic
Stability Control (ESC) system with the electric
power steering to increase the safety level of the
whole vehicle.
In critical situations (e.g. braking on surfaces with
different grip conditions), the ESC system
influences the steering through the DST function
to implement an additional torque contribution
on the steering wheel in order to suggest the
most correct maneuver to the driver.
The coordinated action of the brakes and steering
increases the safety and control of the vehicle.

NOTE:
The DST feature is only meant to help the driver
realize the correct course of action through small
torques on the steering wheel, which means the
effectiveness of the DST feature is highly depen -
dent on the driver’s sensitivity and overall reac -
tion to the applied torque. It is very important to
realize that this feature will not steer the vehicle,
meaning the driver is still responsible for steering
the vehicle.
DRIVE TRAIN CONTROL (DTC) SYSTEM
Some models of this vehicle are equipped with an
All-Wheel Drive (AWD) system, which offers an
optimal drive for countless driving conditions and
road surfaces. The system reduces tire slipping to
a minimum, automatically redistributing the
torque to the front and rear wheels as needed. To maximize fuel savings, the vehicle with AWD
automatically passes to Rear-Wheel Drive (RWD)
when the road and environmental conditions are
such that they wouldn't cause the tires to slip.
When the road and environmental conditions
require better traction, the vehicle automatically
switches to AWD mode.

NOTE:

There may be a brief delay in shifting to
AWD mode after a tire slipping event occurs.
If the system failure symbol switches on, after
starting the engine or while driving, it means
that the AWD system is not working properly. If
the warning message activates frequently, it is
recommended to carry out the maintenance
operations.
ELECTRONIC STABILITY CONTROL (ESC)
S
YSTEM
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 sensors installed on the
vehicle to determine the path that the driver
intends to follow and compares it with the
vehicle’s effective path. When the real path
deviates from the desired path, the ESC system
intervenes to counter the vehicle’s oversteer or
understeer.
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 wheel.
System Intervention
The intervention of the system is indicated by the
flashing of the ESC Warning Light on the
instrument panel, to inform the driver that the
vehicle stability and grip are critical.
WARNING!
Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase the
traction afforded by prevailing road
conditions. ESC cannot prevent accidents,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent accidents resulting from loss of
vehicle control due to inappropriate driver
input for the conditions. Only a safe,
attentive, and skillful driver can prevent
accidents. The capabilities of an ESC
equipped vehicle must never be exploited in
a reckless or dangerous manner which could
jeopardize the user’s safety or the safety of
others.

HILL DESCENT CONTROL (HDC)
S
YSTEM — IF EQUIPPED
The HDC function is an integral part of the
Electronic Stability Control (ESC) system, keeping
the vehicle at a constant speed while descending
a hill by actively controlling the brakes.
HDC aims to create vehicle stability and safer
driving in various situations, including poor grip
conditions and steep descents.
The system has three different modes:
Off: the system is deactivated
Enabled: the system is enabled and ready
to intervene when the activation conditions
are met
Active: the system actively controls the
vehicle speed Enabling The System
To enable the system, push the HDC switch
located on the steering wheel.
HDC Switch
The system is enabled if the car speed is below
20 mph (30 km/h). The system stays enabled
until the car speed reaches 37 mph (60 km/h),
the system is disabled at speeds above 37 mph
(60 km/h).
Activation of the HDC system is indicated by the
white icon appearing in the instrument
cluster display.
HDC Symbol Activation Of The System
Once enabled, the HDC system will activate
automatically if the vehicle is driven on a downhill
slope with sufficient gradient, greater than 8%.
The speed set for the HDC system can be
adjusted using the SET switch located on the
steering wheel.
HDC Speed SET Switch
Once the desired speed has been reached,
release the SET switch and the HDC system will
maintain the set speed. After set speed is
established, the HDC system will automatically
brake to keep the vehicle at the set speed if the
accelerator pedal is released and the vehicle gets
close to the set speed.
It is possible to reduce the set speed with the
brake pedal. When the pedal is released, the
system will adjust the set speed to the new
current speed.
Vehicle modifications, or failure to properly
maintain your vehicle, may change the
handling characteristics of your vehicle, and
may negatively affect the performance of the
ESC system. Changes to the steering system,
suspension, braking system, tire type and
size or wheel size may adversely affect ESC
performance. Improperly inflated and
unevenly worn tires may also degrade ESC
performance. Any vehicle modification or
poor vehicle maintenance that reduces the
effectiveness of the ESC system can
increase the risk of loss of vehicle control,
vehicle rollover, personal injury and death.
WARNING!

TIRE PRESSURE MONITORING SYSTEM
(TPMS)
The vehicle is equipped with a Tire Pressure
Monitoring System (TPMS) that sends the
inflation pressure information of each tire to the
control unit, and will signal the driver in the event
of insufficient tire pressure.
The TPMS uses wireless technology with wheel
rim mounted electronic sensors to monitor tire
pressure levels. Sensors, mounted to each wheel
as part of the valve stem, transmit tire pressure
readings to the receiver module.
Tire pressure will vary with temperature by
approximately 1 psi (7 kPa) for every 12°F
(6.5°C). This means that when the outside
temperature decreases, the tire pressure will also
decrease. Tire pressure should always be set
based on cold inflation tire pressure. This is
defined as the tire pressure after the vehicle has
not been driven for at least three hours, or driven
less than 1 mile (1.6 km) after a three hour
period. The cold tire inflation pressure must not
exceed the maximum inflation pressure molded
into the tire sidewall. The tire pressure will also
increase as the vehicle is driven. This is normal,
and there should be no adjustment for this
increased pressure.
See

Ú
page 224 for information on how to
properly inflate the vehicle’s tires.
The TPMS will signal the driver if pressure falls
below the warning limit for any reason, including
the effects of low temperature and normal loss of
pressure from the tire.
The TPMS will stop indicating insufficient tire
pressure when pressure is equal to or greater than
the prescribed cold inflation level. Therefore, if
insufficient tire pressure is indicated by the ( )
warning light displaying in the instrument cluster,
increase the inflation pressure up to the
prescribed cold inflation value.

The system will automatically update, and the
TPMS Warning Light will turn off once the system
receives the updated tire pressures. The vehicle
may need to be driven for up to 20 minutes above
15 mph (24 km/h) in order for the TPMS to
receive this information.

NOTE:
The TPMS cannot indicate sudden tire pressure
drops (e.g. if a tire bursts). In this case, proceed
with caution and avoid abrupt steering.
Operating Example
For example, your vehicle may have a
recommended cold (parked for more than three
hours) placard pressure of 33 psi (227 kPa). If the
ambient temperature is 68°F (20°C), and the
measured tire pressure is 28 psi (193 kPa), a
temperature drop to 20°F (-7°C) will decrease
the tire pressure to approximately 24 psi
(165 kPa). This tire pressure is low enough to turn
on the Tire Pressure Monitoring Warning Light.
Driving the vehicle may cause the tire pressure to
rise to approximately 28 psi (193 kPa), but the
TPMS Warning Light will still be on. In this
situation, the TPMS Warning Light will turn off
only after the tires are inflated to the vehicle’s
recommended cold placard pressure value.
WARNING!
The system has not been designed to
prevent impacts and cannot detect possible
conditions leading to an accident in
advance. Failure to take into account this
warning may lead to serious or fatal injuries.
The system may activate, assessing the
trajectory of the vehicle, for the presence of
reflecting metal objects different from other
vehicles, such as safety barriers, road signs,
barriers before parking lots, tollgates, level
crossings, gates, railways, objects near road
constructions sites or higher than the vehicle
(e.g. a fly-over). In the same way, the system
may intervene inside multi-story parking lots
or tunnels, or due to a glare on the road
surface. These possible activations are a
consequence of the real driving scenario
coverage by the system and must not be
regarded as faults.
The system has been designed for road use
only. If the vehicle is driven on a track, the
system must be deactivated to avoid
unnecessary warnings. Automatic deacti
-
vation is signaled by the dedicated warning
light/symbol switching on in the instrument
panel

Insufficient Tire Pressure Indication
If an insufficient pressure value is detected on
one or more tires, the warning light in the
instrument cluster will display alongside the
dedicated messages, the system will highlight the
tire or tires with insufficient pressure graphically,
and an acoustic signal will be emitted.In this case, stop the vehicle, check the inflation
pressure of each tire, and inflate the necessary
tire or tires to the correct cold inflation pressure
value, shown on the display or in the dedicated
TPMS menu.
TPMS Temporarily Disabled:
TPMS Check Message
When a system fault is detected, the TPMS
Warning Light will flash on and off for 75 seconds,
and then remain on solid. The system fault will
also sound a chime. If the ignition is cycled, this
sequence will repeat, provided that the system
fault still exists. The TPMS Warning Light will turn
off when the fault condition no longer exists. A
system fault can occur due to any of the following:
Jamming due to electronic devices or driving
next to facilities emitting the same radio
frequencies as the TPMS sensors.
Installing some form of aftermarket window
tinting that affects radio wave signals.
Packed snow or ice around the wheels or
wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with
TPMS sensors.
After the punctured tire has been repaired with
the original tire sealant contained in the tire kit,
the previous condition must be restored so that
the warning light is off during normal driving.
TPMS Deactivation
The TPMS can be deactivated by replacing all
four wheel and tire assemblies (road tires) with
wheel and tire assemblies that do not have TPMS
sensors, such as when installing winter wheel
and tire assemblies on your vehicle. To deactivate the TPMS, first replace all four
wheel and tire assemblies (road tires) with tires
not equipped with Tire Pressure Monitoring
System (TPMS) sensors. Then, drive the vehicle
for 20 minutes above 15 mph (24 km/h). The
TPMS will chime, the TPMS Warning Light will
flash on and off for 75 seconds and then remain
on. The instrument cluster will display the
“SERVICE TPM SYSTEM” message and then
display dashes (--) in place of the pressure values.
Beginning with the next ignition switch cycle, the
TPMS will no longer chime or display the
“SERVICE TPM SYSTEM” message in the
instrument cluster. Instead, dashes (--) will
remain in place of the pressure values.
To reactivate the TPMS, replace all four wheel
and tire assemblies (road tires) with tires
equipped with TPMS sensors. Then, drive the
vehicle for up to 20 minutes above 15 mph
(24 km/h). The TPMS will chime, the TPMS
Warning Light will flash on and off for 75 seconds
and then turn off. The instrument cluster will
display the “SERVICE TPM SYSTEM” message
and then display pressure values in place of the
dashes. On the next ignition switch cycle the
“SERVICE TPM SYSTEM” message will no longer
be displayed, as long as no system fault exists.

NOTE:

The TPMS is not intended to replace normal
tire care and maintenance, or to provide
warning of a tire failure or condition.
The TPMS should not be used as a tire
pressure gauge while adjusting your tire
pressure.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS
pressures and warning have been
established for the tire size equipped on your
vehicle. Undesirable system operation or
sensor damage may result when using
replacement equipment that is not of the
same size, type, and/or style. The TPMS
sensor is not designed for use on
aftermarket wheels and may contribute to a
poor overall system performance or sensor
damage. Customers are encouraged to use
Original Equipment Manufacturer (OEM)
wheels to ensure proper TPMS feature
operation.
Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended
that you take your vehicle to an authorized
dealer to have your sensor function checked.
After inspecting or adjusting the tire pressure
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the
valve stem, which could damage the TPMS
sensor.

PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones, nails,
glass, or other objects lodged in the tread or
sidewall. Inspect the tread for cuts and cracks.
Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the
tires (including spare) for proper cold inflation
pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel, or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
EXHAUST GAS
The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.
Whenever a change is noticed in the sound of the
exhaust system, when exhaust fumes can be
detected inside the vehicle, or when the
underside or rear of the vehicle is damaged, have
a competent mechanic inspect the complete
exhaust system and adjacent body areas for
broken, damaged, deteriorated, or mispositioned parts. Open seams or loose connections could
permit exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust
system each time the vehicle is raised for
lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS
WARNING!

Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you. To
avoid breathing (CO), follow these safety tips:

Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If you are required to drive with the trunk/
liftgate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to
prevent carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in a
closed area, such as a garage, and never sit
in a parked vehicle with the engine running
for an extended period. If the vehicle is
stopped in an open area with the engine
running for more than a short period, adjust
the ventilation system to force fresh, outside
air into the vehicle.
Guard against carbon monoxide with proper
maintenance. Have the exhaust system
inspected every time the vehicle is raised.
Have any abnormal conditions repaired
promptly. Until repaired, drive with all side
windows fully open.
When exiting the vehicle, always make sure
the ignition is in the off position, remove the
key fob from the vehicle, and lock your
vehicle.
