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.

In Automatic Locking Mode, the shoulder belt is
automatically pre-locked. The seat belt will still
retract to remove any slack in the shoulder belt.
Use the Automatic Locking Mode anytime a child
restraint is installed in a seating position that has
a seat belt with this feature. Children 12 years old
and under should always be properly restrained
in the rear seat of a vehicle with a rear seat.
How To Engage The Automatic Locking Mode
1. Buckle the combination lap and shoulder belt.
2. Grab the shoulder portion and pull downward until the entire seat belt is extracted.
3. Allow the seat belt to retract. As the seat belt retracts, you will hear a clicking sound. This
indicates the seat belt is now in the Auto -
matic Locking Mode. How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt and
allow it to retract completely to disengage the
Automatic Locking Mode and activate the vehicle
sensitive (emergency) locking mode.
SUPPLEMENTAL RESTRAINT SYSTEMS

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 position, 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.
WARNING!
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!
The seat belt assembly must be replaced if
the switchable Automatic Locking Retractor
(ALR) feature or any other seat belt function
is not working properly when checked
according to the procedures in the Service
Manual.
Failure to replace the seat belt assembly
could increase the risk of injury in collisions.
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.

Driver And Passenger Front Air Bag
Features
The Advanced Front Air Bag system has
multistage 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
deployment. 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.
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!
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 collision 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.

Front Air Bag Operation
Front Air Bags are designed to provide additional
protection by supplementing the seat belts. Front
air bags are not expected to reduce the risk of
injury in rear, side, or rollover 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
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 Supple-
mental 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, preten -
sioners, 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 occupant
injury during certain side impacts, in addition 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 properly, 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.

Supplemental Side Air Bag Inflatable Curtains
(SABICs)
This vehicle is equipped with Supplemental Side
Air Bag Inflatable Curtains (SABICs).
Supplemental Side Air Bag Inflatable Curtains
(SABICs) are located above the side windows. The
trim covering the SABICs is labeled “SRS AIRBAG”
or “AIRBAG.”Supplemental Side Air Bag Inflatable Curtain (SABIC) Location
SABICs may help reduce the risk of head and
other injuries to front and rear seat outboard
occupants in certain side impacts, in addition to
the injury reduction potential provided by the seat
belts and body structure.
The SABIC deploys downward, covering the side
windows. An inflating SABIC pushes the outside
edge of the headliner out of the way and covers
the window. The SABICs inflate with enough force
to injure occupants if they are not belted and
seated properly, or if items are positioned in the
area where the SABICs inflate. Children are at an
even greater risk of injury from a deploying air
bag. The SABICs may help reduce the risk of partial or
complete ejection of vehicle occupants through
side windows in certain side impact events.
Side Impacts
The Side Air Bags are designed to activate in
certain side impacts. The Occupant Restraint
Controller (ORC) determines whether the
deployment of the Side Air Bags in a particular
impact event is appropriate, based on the
severity and type of collision. The side impact
sensors aid the ORC in determining the
appropriate response to impact events. The
system is calibrated to deploy the Side Air Bags
on the impact side of the vehicle during impacts
that require Side Air Bag occupant protection.
In side impacts, the Side Air Bags deploy
independently; a left side impact deploys the
left Side Air Bags only and a right-side impact
deploys the right Side Air Bags only. Vehicle
damage by itself is not a good indicator of
whether or not Side Air Bags should have
deployed.
The Side Air Bags will not deploy in all side
collisions, including some collisions at certain
angles, or some side collisions that do not impact
the area of the passenger 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.
WARNING!
Do not mount equipment, or stack luggage or
other cargo up high enough to block the
deployment of the SABICs. The trim covering
above the side windows where the SABIC
and its deployment path are located should
remain free from any obstructions.
In order for the SABICs to work as intended,
do not install any accessory items in your
vehicle which could alter the roof. Do not add
an aftermarket sunroof to your vehicle. Do
not add roof racks that require permanent
attachments (bolts or screws) for installation
on the vehicle roof. Do not drill into the roof
of the vehicle for any reason.
WARNING!
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
appropriate) 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.
23_GU_OM_EN_USC_t.book Page 166

167

NOTE:
Air bag covers may not be obvious in the interior
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 particular
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 rollover
sensing system determines if a rollover event
may be in progress and whether deployment 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 preten
-
sioners 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.

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 irritate
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 manufacturer’s instructions for
cleaning.
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 collisions, Side
Air Bags won’t deploy at all. Always wear your
seat belt even though you have Side Air Bags.

FUSES
General Information
The fuses protect electrical systems against
excessive current.
When a device does not work, you must check the
electrical circuit inside of the fuse for a break/
melt.
Also, please be aware that using power outlets for
extended periods of time with the engine off may
result in vehicle battery discharge.
Blade Fuses
To avoid contamination from foreign matter
or moisture, use only new brake fluid or fluid
that has been in a tightly closed container.
Keep the master cylinder reservoir cap
secured at all times. Brake fluid in an open
container absorbs moisture from the air
resulting in a lower boiling point. This may
cause it to boil unexpectedly during hard or
prolonged braking, resulting in sudden brake
failure. This could result in a collision.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces, care should be taken to avoid its
contact with these surfaces.
Do not allow petroleum-based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This could
result in a collision.
WARNING! CAUTION!

Do not use chemical flushes in your
transmission as the chemicals can damage your
transmission components. Such damage is not
covered by the New Vehicle Limited Warranty.

CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An
authorized dealer has the proper tools to
adjust the fluid level accurately.
