If the vehicle has two seating rows, roof-rail
airbags for the driver, front outboard
passenger, and second row outboard
passengers are in the ceiling above the side
windows. If the vehicle has three or more
seating rows, roof-rail airbags for the driver,
front outboard passenger, and second and
third row outboard passengers are in the
ceiling above the side windows.

Warning (Continued)
that person causing severe injury or even
death. The path of an inflating airbag
must be kept clear. Do not put anything
between an occupant and an airbag, and
do not attach or put anything on the
steering wheel hub or on or near any
other airbag covering.
Do not use seat accessories that block the
inflation path of a seat-mounted side
impact airbag.
Never secure anything to the roof of a
vehicle with roof-rail airbags by routing a
rope or tie‐down through any door or
window opening. If you do, the path of
an inflating roof-rail airbag will be
blocked.
When Should an Airbag Inflate?
This vehicle is equipped with one or more
airbags. SeeAirbag System 037. Airbags are
designed to inflate if the impact exceeds the
specific airbag system's deployment
threshold. Deployment thresholds are used
to predict how severe a crash is likely to be
in time for the airbags to inflate and help
restrain the occupants. The vehicle has electronic sensors which help the airbag
system determine the severity of the
impact. Deployment thresholds can vary
with specific vehicle design.
Frontal airbags are designed to inflate in
moderate to severe frontal or near-frontal
crashes to help reduce the potential for
severe injuries mainly to the driver or front
outboard passenger head and chest.
Whether the frontal airbags will or should
deploy is not based primarily on how fast
the vehicle is traveling. It depends largely
on what you hit, the direction of the
impact, and how quickly the vehicle
slows down.
Frontal airbags may inflate at different crash
speeds depending on whether the vehicle
hits an object straight on or at an angle,
and whether the object is fixed or moving,
rigid or deformable, narrow or wide.
Frontal airbags are not intended to inflate
during vehicle rollovers, rear impacts, or in
many side impacts.
Seat-mounted side impact airbags,
if equipped, are designed to inflate in
moderate to severe side crashes depending
on the location of the impact. Seat-mounted
side impact airbags are not designed to

serviced. There are parts of the airbag
system in several places around the vehicle.
Your dealer and the service manual have
information about servicing the vehicle and
the airbag system. To purchase a service
manual, see Publication Ordering
Information 0265.
{Warning
For up to 10 seconds after the vehicle is
turned off and the battery is
disconnected, an airbag can still inflate
during improper service. You can be
injured if you are close to an airbag
when it inflates. Avoid yellow connectors.

procedures, and make sure the person
performing work for you is qualified to
do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change the vehicle's
frame, bumper system, height, front end,
or side sheet metal may keep the airbag
system from working properly.
The operation of the airbag system can also
be affected by changing, including
improperly repairing or replacing, any parts
of the following:
.Airbag system, including airbag modules,
front or side impact sensors, sensing and
diagnostic module, or airbag wiring
.Front seats, including stitching, seams or
zippers
.Seat belts
.Steering wheel, instrument panel, ceiling
trim, or pillar garnish trim
.Inner door seals, including speakers Your dealer and the service manual have
information about the location of the airbag
modules and sensors, sensing and diagnostic
module, and airbag wiring along with the
proper replacement procedures.
If the vehicle has rollover roof-rail airbags,
see
Different Size Tires and Wheels 0219 for
additional important information.
If the vehicle must be modified because you
have a disability and have questions about
whether the modifications will affect the
vehicle's airbag system, or if you have
questions about whether the airbag system
will be affected if the vehicle is modified for
any other reason, call Customer Assistance.

The 110/120 volt power outlet is on the
instrument panel.
An indicator light on the outlet turns on to
show it is in use. The light comes on when
the ignition is on, equipment requiring less
than 150 watts is plugged into the outlet,
and no system fault is detected.
The indicator light does not come on when
the ignition is off, or if the equipment is not
fully seated into the outlet.
If equipment is connected using more than
150 watts or a system fault is detected, a
protection circuit shuts off the power supply
and the indicator light turns off. To reset
the circuit, unplug the item and plug it back
in or turn the Retained Accessory Power
(RAP) off and then back on. SeeRetained
Accessory Power (RAP) 0133.
The power outlet is not designed for the
following, and may not work properly if
they are plugged in:
.Equipment with high initial peak wattage,
such as compressor-driven refrigerators
and electric power tools
.Other equipment requiring an extremely
stable power supply, such as
microcomputer-controlled electric blankets
and touch sensor lamps
.Medical equipment
Cigarette Lighter
If equipped with a cigarette lighter, to heat,
push it in all the way and let go. When it is
ready for use, it will pop back out by itself.
Do not use the lighter to plug in accessory
devices. Use the power outlets provided.
Caution
Holding a cigarette lighter in while it is
heating does not let the lighter back
away from the heating element when it
is hot. Damage from overheating can
occur to the lighter or heating element,
or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating.
Ashtrays
If equipped with a removable ashtray, it can
be placed into the front floor console
cupholder. Open the cover to use.

ashtray.
Warning Lights, Gauges, and
Indicators
Warning lights and gauges can signal that
something is wrong before it becomes
serious enough to cause an expensive repair
or replacement. Paying attention to the
warning lights and gauges could prevent
injury.
Some warning lights come on briefly when
the engine is started to indicate they are
working. When one of the warning lights
comes on and stays on while driving,
or when one of the gauges shows there
may be a problem, check the section that
explains what to do. Waiting to do repairs
can be costly and even dangerous.

When the engine is not running, but the
ignition is on, this gauge shows the
battery's state of charge in DC volts.
When the engine is running, the gauge
shows the condition of the charging system.
Readings between the low and high warning
zones indicate the normal operating range.
Readings in the low warning zone may occur
when a large number of electrical
accessories are operating in the vehicle and
the engine is left at an idle for an extended
period. This condition is normal since the
charging system is not able to provide full
power at engine idle. As engine speeds are
increased, this condition should correct itself
as higher engine speeds allow the charging
system to create maximum power.
The vehicle can be only driven for a short
time with the reading in either warning
zone. If it must be driven, turn off all
unnecessary accessories.
Readings in either warning zone indicate a
possible problem in the electrical system.
Have the vehicle serviced as soon as
possible.Seat Belt Reminders
Driver Seat Belt Reminder Light
There is a seat belt reminder light on the
instrument cluster.
When the vehicle is started, this light
flashes and a chime may come on to remind
the driver to fasten their seat belt. Then the
light stays on solid until the belt is buckled.
This cycle may continue several times if the
driver remains or becomes unbuckled while
the vehicle is moving.
If the driver seat belt is buckled, neither the
light nor the chime comes on.
Airbag Readiness Light
This light shows if there is an electrical
problem with the airbag system. It is
located in the instrument cluster. The
system check includes the airbag sensor(s),
the airbag on-off switch, the pretensioners
(if equipped), the airbag modules, thewiring, and the crash sensing and diagnostic
module. For more information on the airbag
system, see
Airbag System 037.
The airbag readiness light comes on for
several seconds when the vehicle is started.
If the light does not come on then, have it
fixed immediately.
{Warning
If the airbag readiness light stays on
after the vehicle is started or comes on
while driving, it means the airbag system
might not be working properly. The
airbags in the vehicle might not inflate in
a crash, or they could even inflate
without a crash. To help avoid injury,
have the vehicle serviced right away.
If there is a problem with the airbag
system, a Driver Information Center (DIC)
message may also come on.

Lighting 93
The vehicle has a light sensor on the top of
the instrument panel. Do not cover the
sensor; otherwise the system will come on
whenever the ignition is on.
The system may also turn on the headlamps
when driving through a parking garage or
tunnel.
There is a delay in the transition between
the daytime and nighttime operation of the
Daytime Running Lamps (DRL) and the
automatic headlamp system so that driving
under bridges or bright overhead street
lights does not affect the system. The DRL
and automatic headlamp system are only
affected when the light sensor sees a
change in lighting lasting longer than the
delay.
If the vehicle is started in a dark garage, the
automatic headlamp system comes on
immediately. Once the vehicle leaves the
garage, it takes approximately 30 seconds
for the automatic headlamp system to
change to DRL if it is light outside. During
that delay, the instrument cluster may not
be as bright as usual. Make sure the
instrument panel brightness control is in the
full bright position. SeeInstrument Panel
Illumination Control 094. To idle the vehicle with the automatic
headlamp system off, turn the control off.

Park Assist
If equipped, the Rear Park Assist (RPA)
system uses sensors on the rear bumper to
assist with parking and avoiding objects
while in R (Reverse).
{Warning
The Park Assist system does not detect
children, pedestrians, bicyclists, animals,
or objects below the bumper or that are
too close or too far from the vehicle. It is
not available at speeds greater than
8 km/h (5 mph). To prevent injury, death,
or vehicle damage, even with Park Assist,
always check the area around the vehicle

How the System Works
RPA comes on automatically when the shift
lever is moved into R (Reverse). A single
beep sounds to indicate the system is
working.
RPA operates only at speeds less than
8 km/h (5 mph).An obstacle detection is indicated by beeps.
The time between beeps gets shorter as the
vehicle approaches the obstacle. Repeated
beeps are heard when the distance is less
than 30 cm (12 in).
To be detected, objects must be at least
25 cm (10 in) off the ground and below rear
door level. Objects must also be within 2.5 m
(8 ft) from the rear bumper. This distance
may be less during warmer or humid
weather.

Forward Collision Alert (FCA)
System
If equipped, the FCA system may help to
avoid or reduce the harm caused by
front-end crashes. When approaching a
vehicle ahead too quickly, FCA provides a
red flashing alert on the windshield and
rapidly beeps. FCA also lights an amber
visual alert if following another vehicle
much too closely.
FCA detects vehicles within a distance of
approximately 60 m (197 ft) and operates at
speeds above 40 km/h (25 mph).
{Warning
FCA is a warning system and does not
apply the brakes. When approaching a
slower-moving or stopped vehicle ahead
too rapidly, or when following a vehicle
too closely, FCA may not provide a
warning with enough time to help avoid
a crash. It also may not provide any
warning at all. FCA does not warn of
pedestrians, animals, signs, guardrails,
bridges, construction barrels, or other(Continued)

Detecting the Vehicle Ahead
FCA warnings will not occur unless the FCA
system detects a vehicle ahead. When a
vehicle is detected, the vehicle ahead
indicator will display green. Vehicles may
not be detected on curves, highway exit
ramps, or hills, due to poor visibility; or if a
vehicle ahead is partially blocked by
pedestrians or other objects. FCA will not
detect another vehicle ahead until it is
completely in the driving lane.
{Warning
FCA does not provide a warning to help
avoid a crash, unless it detects a vehicle.
FCA may not detect a vehicle ahead if
the FCA sensor is blocked by dirt, snow,
or ice, or if the windshield is damaged.
It may also not detect a vehicle on
winding or hilly roads, or in conditions
that can limit visibility such as fog, rain,
or snow, or if the headlamps or
windshield are not cleaned or in proper
condition. Keep the windshield,
headlamps, and FCA sensors clean and in
good repair.
