The function of this system can also be tempo-
rarily reduced due to obstructions such as
mud, dirt or ice on the fascia/bumper. In such
cases, a dedicated message will be shown on
the display and the system will be deactivated.
This message can sometimes appear in condi -
tions of high reflectivity (e.g. tunnels with
reflective tiles or ice or snow). When the condi -
tions limiting the system functions end, it will
go back to normal and complete operation.
In certain cases, this dedicated message
could be displayed when the radar is not
detecting any vehicles or objects within its
view range.
If atmospheric conditions are not the reason
behind this message, check if the sensor is
dirty. It could be necessary to clean or remove
any obstructions in the area.
If the message appears frequently, even in the
absence of atmospheric conditions such as
snow, rain, mud or other obstructions, contact
an authorized dealer for a sensor alignment
check.
In the absence of visible obstructions, manu -
ally removing the decorative cover trim and
cleaning the radar surface could be required.
Have this operation performed at an autho -
rized dealer.
NOTE:

It is recommended that you do not install
devices, accessories or aerodynamic attach
-
ments in front of the sensor or darken it in any
way, as this can compromise the correct func -
tioning of the system.
Frontal Collision Alarm With Active Braking — If
Equipped
If this function is selected, the brakes are
operated to reduce the speed of the vehicle in
the event of potential frontal impact.
This function applies an additional braking
pressure if the braking pressure applied by the
driver does not suffice to prevent potential
frontal impact.
The function is active with speed above 2 mph
(4 km/h).

NOTE:

When using an automatic car wash it is recom -
mended to deactivate the system through the
settings of the radio system. The system may
detect the presence of a car, a wall or another
obstacle and activate.
Driving In Special Conditions
In certain driving conditions, system interven -
tion might be unexpected or delayed. The
driver must therefore be very careful, keeping
control of the vehicle to drive in complete
safety.Driving close to a bend.
The vehicle ahead is leaving a roundabout.
Vehicles with small dimensions and/or not
aligned in the driving lane.
Lane change by other vehicles.
Vehicles traveling at right angles to the
vehicle.

NOTE:

In particularly complex traffic conditions,
the driver can deactivate the system manu -
ally through the Information and Entertain -
ment system.
If the driver depresses the brake pedal fully
or makes an excessive steering maneuver
during system operation, the automatic
braking function may deactivate (e.g. to
allow a possible maneuver to avoid the
obstacle).
The FCW system is automatically deacti -
vated when operating in race mode and a
warning message will be displayed on the
instrument cluster.

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 pres-
sure 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 233 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. There
-
fore, if insufficient tire pressure is indicated by
the ( ) warning light displaying in the instru -
ment 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 pres -
sure 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 recom -
mended 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
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 conse -
quence 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

Supplemental Restraint Systems (SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask an authorized
dealer.
The air bag system must be ready to protect
you in a collision. The Occupant Restraint
Controller (ORC) monitors the internal circuits
and interconnecting wiring associated with the
electrical Air Bag System Components. Your
vehicle may be equipped with the following Air
Bag System Components:

Air Bag Warning Light
The Occupant Restraint Controller
(ORC) monitors the readiness of the
electronic parts of the air bag system
whenever the ignition switch is in the
START or ON/RUN position. If the ignition
switch is in the OFF position or in the ACC posi -
tion, the air bag system is not on and the air
bags will not inflate.
The ORC contains a backup power supply
system that may deploy the air bag system
even if the battery loses power or it becomes
disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in
the instrument panel for approximately four to
eight seconds for a self-check when the igni -
tion switch is first in the ON/RUN position.
After the self-check, the Air Bag Warning Light
will turn off. If the ORC detects a malfunction
in any part of the system, it turns on the Air
Bag Warning Light, either momentarily or continuously. A single chime will sound to alert
you if the light comes on again after initial
startup.
The ORC also includes diagnostics that will illu
-
minate the instrument panel Air Bag Warning
Light if a malfunction is detected that could
affect the air bag system. The diagnostics also
record the nature of the malfunction. While
the air bag system is designed to be mainte -
nance free, if any of the following occurs, have
an authorized dealer service the air bag
system immediately.The Air Bag Warning Light does not come on
during the four to eight seconds when the
ignition switch is first in the ON/RUN posi -
tion.
The Air Bag Warning Light remains on after
the four to eight-second interval.
The Air Bag Warning Light comes on inter-
mittently or remains on while driving.

NOTE:

If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant
Restraint Controller (ORC) may also be
disabled. In this condition the air bags may not
be ready to inflate for your protection. Have an
authorized dealer service the air bag system
immediately.
Do not use the Automatic Locking Mode to
restrain occupants who are wearing the
seat belt or children who are using booster
seats. The locked mode is only used to
install rear-facing or forward-facing child
restraints that have a harness for
restraining the child.

Redundant Air Bag Warning Light
If a fault with the Air Bag Warning
Light is detected, which could affect
the Supplemental Restraint System
(SRS), the Redundant Air Bag
Warning Light will illuminate on the instrument
panel. The Redundant Air Bag Warning Light
will stay on until the fault is cleared. In addi -
tion, a single chime will sound to alert you that
the Redundant Air Bag Warning Light has
come on and a fault has been detected. If the
Redundant Air Bag Warning Light comes on
intermittently or remains on while driving have
an authorized dealer service the vehicle imme -
diately.

Front Air Bags
This vehicle has front air bags and lap/
shoulder belts for both the driver and front
passenger. The front air bags are a supple -
ment to the seat belt restraint systems. The
driver front air bag is mounted in the center of
the steering wheel. The passenger front air
bag is mounted in the instrument panel, above
the glove compartment. The words “SRS
AIRBAG” or “AIRBAG” are embossed on the air
bag covers.

Driver And Passenger Front Air Bag
Features
The Advanced Front Air Bag system has multi -
stage driver and front passenger air bags. This
system provides output appropriate to the
severity and type of collision as determined by
the Occupant Restraint Controller (ORC),
which may receive information from the front
impact sensors (if equipped) or other system
components.
The first stage inflator is triggered immediately
during an impact that requires air bag deploy -
ment. A low energy output is used in less
severe collisions. A higher energy output is
used for more severe collisions.
This vehicle may be equipped with a driver
and/or front passenger seat belt buckle
switch that detects whether the driver or front
passenger seat belt is buckled. The seat belt
buckle switch may adjust the inflation rate of
the Advanced Front Air Bags.

This vehicle may be equipped with driver and/or
front passenger seat track position sensors that
may adjust the inflation rate of the Advanced
Front Air Bags based upon seat position.

Front Air Bag Operation
Front Air Bags are designed to provide addi -
tional protection by supplementing the seat
belts. Front air bags are not expected to
reduce the risk of injury in rear, side, or roll -
over collisions. The front air bags will not
deploy in all frontal collisions, including some
that may produce substantial vehicle damage
— for example, some pole collisions, truck
underrides, and angle offset collisions.
On the other hand, depending on the type and
location of impact, front air bags may deploy in
crashes with little vehicle front-end damage
but that produce a severe initial deceleration.
Because air bag sensors measure vehicle
deceleration over time, vehicle speed and
WARNING!
Being too close to the steering wheel or
instrument panel during front air bag
deployment could cause serious injury,
including death. Air bags need room to
inflate. Sit back, comfortably extending
your arms to reach the steering wheel or
instrument panel.
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
front air bag can cause death or serious
injury to a child 12 years or younger,
including a child in a rear-facing child
restraint.
Never install a rear-facing child restraint in
the front seat of a vehicle. Only use a
rear-facing child restraint in the rear seat.
If the vehicle does not have a rear seat, do
not transport a rear-facing child restraint
in that vehicle.
WARNING!
No objects should be placed over or near
the air bag on the instrument panel or
steering wheel because any such objects
could cause harm if the vehicle is in a colli -
sion severe enough to cause the air bag to
inflate.
Do not put anything on or around the air
bag covers or attempt to open them
manually. You may damage the air bags
and you could be injured because the air
bags may no longer be functional. The
protective covers for the air bag cushions
are designed to open only when the air
bags are inflating.
Relying on the air bags alone could lead to
more severe injuries in a collision. The air
bags work with your seat belt to restrain
you properly. In some collisions, air bags
won’t deploy at all. Always wear your seat
belts even though you have air bags.

damage by themselves are not good indicators
of whether or not an air bag should have
deployed.
Seat belts are necessary for your protection in
all collisions, and also are needed to help keep
you in position, away from an inflating air bag.
When the Occupant Restraint Controller (ORC)
detects a collision requiring the front air bags,
it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the front
air bags.
The steering wheel hub trim cover and the
upper passenger side of the instrument panel
separate and fold out of the way as the air
bags inflate to their full size. The front air bags
fully inflate in less time than it takes to blink
your eyes. The front air bags then quickly
deflate while helping to restrain the driver and
front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the
knees of the driver and front passenger, and
position the front occupants for improved
interaction with the front air bags.
Supplemental Driver And Front Passenger
Knee Air Bags
This vehicle is equipped with a Supplemental
Driver Knee Air Bag mounted in the instrument
panel below the steering column and a
Supplemental Passenger Knee Air Bag
mounted in the instrument panel below the
glove compartment. The Supplemental Knee
Air Bags provide enhanced protection during a
frontal impact by working together with the
seat belts, pretensioners, and front air bags.
Supplemental Side Air Bags
Supplemental Seat-Mounted Side Air Bags
(SABs)
This vehicle is equipped with Supplemental
Seat-Mounted Side Air Bags (SABs).
Supplemental Seat-Mounted Side Air Bags
(SABs) are located in the outboard side of the
front seats. The SABs are marked with “SRS
AIRBAG” or “AIRBAG” on a label or on the seat
trim on the outboard side of the seats.
The SABs may help to reduce the risk of occu-
pant injury during certain side impacts, in addi-
tion to the injury reduction potential provided
by the seat belts and body structure. Front Supplemental Seat-Mounted Side Air
Bag
When the SAB deploys, it opens the seam on
the outboard side of the seatback’s trim cover.
The inflating SAB deploys through the seat
seam into the space between the occupant
and the door. The SAB moves at a very high
speed and with such a high force that it could
injure occupants if they are not seated prop -
erly, or if items are positioned in the area
where the SAB inflates. Children are at an
even greater risk of injury from a deploying air
bag.
WARNING!
Do not drill, cut, or tamper with the knee
impact bolsters in any way.
Do not mount any accessories to the knee
impact bolsters such as alarm lights,
stereos, citizen band radios, etc.
WARNING!
Do not use accessory seat covers or place
objects between you and the Side Air Bags;
the performance could be adversely
affected and/or objects could be pushed
into you, causing serious injury.

compartment. The Side Air Bags may deploy
during angled or offset frontal collisions where
the front air bags deploy.
Side Air Bags are a supplement to the seat belt
restraint system. Side Air Bags deploy in less
time than it takes to blink your eyes.
NOTE:

Air bag covers may not be obvious in the inte-
rior trim, but they will open during air bag
deployment.
Rollover Events
Side Air Bags and seat belt pretensioners are
designed to activate in certain rollover events.
The Occupant Restraint Controller (ORC)
determines whether deployment in a partic -
ular rollover event is appropriate, based on the
severity and type of collision. Vehicle damage
by itself is not a good indicator of whether or
not Side Air Bags and seat belt pretensioners
should have deployed.
The Side Air Bags and seat belt pretensioners
will not deploy in all rollover events. The roll -
over sensing system determines if a rollover
event may be in progress and whether deploy -
ment is appropriate. In the event the vehicle
experiences a rollover or near rollover event, and deployment is appropriate, the rollover
sensing system will deploy the side air bags
and seat belt pretensioners on both sides of
the vehicle.
The SABICs may help reduce the risk of partial
or complete ejection of vehicle occupants
through side windows in certain rollover or
side impact events.

Occupants, including children, who are up
against or very close to Side Air Bags can
be seriously injured or killed. Occupants,
including children, should never lean on or
sleep against the door, side windows, or
area where the side air bags inflate, even
if they are in an infant or child restraint.

Seat belts (and child restraints where appro -
priate) are necessary for your protection in
all collisions. They also help keep you in
position, away from an inflating Side Air Bag.
To get the best protection from the Side Air
Bags, occupants must wear their seat belts
properly and sit upright with their backs
against the seats. Children must be properly
restrained in a child restraint or booster seat
that is appropriate for the size of the child.

WARNING!
Side Air Bags need room to inflate. Do not
lean against the door or window. Sit
upright in the center of the seat.
Being too close to the Side Air Bags during
deployment could cause you to be
severely injured or killed.
Relying on the Side Air Bags alone could
lead to more severe injuries in a collision.
The Side Air Bags work with your seat belt
to restrain you properly. In some colli -
sions, Side Air Bags won’t deploy at all.

If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.

NOTE:

Front and/or side air bags will not deploy in all
collisions. This does not mean something is
wrong with the air bag system.
If you do have a collision which deploys the air
bags, any or all of the following may occur:
The air bag material may sometimes cause
abrasions and/or skin reddening to the
occupants as the air bags deploy and
unfold. The abrasions are similar to friction
rope burns or those you might get sliding
along a carpet or gymnasium floor. They are
not caused by contact with chemicals. They
are not permanent and normally heal
quickly. However, if you haven’t healed
significantly within a few days, or if you have
any blistering, see your doctor immediately.
As the air bags deflate, you may see some
smoke-like particles. The particles are a
normal by-product of the process that
generates the non-toxic gas used for air bag
inflation. These airborne particles may irri-
tate the skin, eyes, nose, or throat. If you
have skin or eye irritation, rinse the area
with cool water. For nose or throat irritation,
move to fresh air. If the irritation continues,
see your doctor. If these particles settle on
your clothing, follow the garment manufac -
turer’s instructions for cleaning. Do not drive your vehicle after the air bags
have deployed. If you are involved in another
collision, the air bags will not be in place to
protect you.

NOTE:

Air bag covers may not be obvious in the
interior trim, but they will open during air
bag deployment.
After any collision, the vehicle should be
taken to an authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communica
-
tion network remains intact, and the power
remains intact, depending on the nature of the
event, the Occupant Restraint Controller (ORC)
will determine whether to have the Enhanced
Accident Response System perform the
following functions:
Cut off fuel to the engine (if equipped)
Cut off battery power to the electric motor (if
equipped)
Flash hazard lights as long as the battery
has power
Turn on the interior lights, which remain on
as long as the battery has power or for
15 minutes from the intervention of the
Enhanced Accident Response System
Unlock the power door locks
Your vehicle may also be designed to perform
any of these other functions in response to the
Enhanced Accident Response System:
Turn off the Fuel Filter Heater, Turn off the
HVAC Blower Motor, Close the HVAC Circula -
tion Door
Cut off battery power to the:
• Engine
• Electric Motor (if equipped)
• Electric power steering

11. Apply the adhesive label from the sealantbottle where it can be easily seen by the
driver as a reminder that the tire has been
treated with a Tire Service Kit, as well as
not to exceed the speed restriction for the
treated tire.
NOTE:

Only use original sealant cartridges, which can
be purchased at an authorized dealer.
Checking And Restoring Tire Pressure
The compressor can also be used to check
and, if necessary, restore the tire pressure.
Proceed as follows:
1. Make sure that the power switch is in the
O (off) position.
2. Connect the hose directly to the valve on the tire to be inflated.
3. Insert the plug into the socket in the passenger compartment or in the cargo
area and start the engine.
4. Start the compressor by putting the power switch to I (on). As soon as the correct
pressure is reached, put the power switch
to O (off). Air Compressor And Components
If the tire is overinflated, reduce the pressure
by pushing the PSI/BAR button and releasing
it when the correct pressure is reached.
JUMP STARTING
If your vehicle has a discharged battery, it can
be jump started using a set of jumper cables
and a battery in another vehicle, or by using a
portable battery booster pack. Jump starting
can be dangerous if done improperly, so
please follow the procedures in this section
carefully.

NOTE:

When using a portable battery booster pack,
follow the manufacturer's operating instruc -
tions and precautions.
WARNING!
Tire Service Kit is not a permanent flat tire
repair. Have the tire inspected and repaired
or replaced after using Tire Service Kit. Do
not exceed 50 mph (80 km/h) until the tire
is repaired or replaced. Failure to follow this
warning can result in injuries that are
serious or fatal to you, your passengers,
and others around you. Have the tire
checked as soon as possible at an
authorized dealer.
WARNING!
Do not adhere the speed restriction sticker
to the padded area on the steering wheel.
Adhering the speed restriction sticker to the
padded area on the steering wheel is
dangerous because the air bag may not
operate (deploy) normally resulting in
serious injury. In addition, do not adhere
the sticker to areas where warning lights or
the speedometer cannot be viewed.
