Cargo Lamp
The cargo lamp is located in the rear of the
vehicle, above the liftgate opening. It comes on
automatically each time you open the doors, if the
interior lamp control is in the DOOR position.
There are two reading lamps located on the cargo
lamp. To turn either reading lamp on or off,
press the button located next to the lamp.
Battery Run-Down Protection
Your vehicle has a feature to help prevent you
from draining the battery, in case you accidentally
leave the interior or exterior lamps on. If the
interior lamps are left on while the ignition is in
OFF, they will automatically turn off after
10 minutes. If the exterior lamps are left on while
the ignition is in OFF with all doors and the
liftgate closed, they will automatically turn off after
10 minutes.
If your vehicle has less than 14 miles (24 km) on
the odometer, the battery saver will turn off
the lamps after only three minutes.If the interior lamps are turned off as a result of
the battery saver feature, they may be turned back
on by turning the interior lamp control to OFF
and then back to ON. The battery saver will not
turn the interior lamps off automatically after doing
this. They will have to be turned off manually.
Instrument Panel Switchbank
There is an instrument panel switchbank located
below the climate controls. It contains switches
or blanks that will vary with the options that are on
your vehicle.
The switches you may have are:
Rear Window Wiper/Washer. SeeWindshield
Washer on page 180.
Traction Disable. SeeTraction Control System
(TCS) on page 310.
Park Aid Disable. SeeUltrasonic Rear Parking
Assist (URPA) on page 196.
Heated Seats. SeeHeated Seats on page 11.

To clean the HUD, spray household glass cleaner
on a soft, clean cloth. Wipe the HUD lens gently,
then dry it. Do not spray cleaner directly on the lens
because the cleaner could leak into the unit.
If the ignition is on and you cannot see the HUD
image, check to see if one of the following
conditions exist:
The HUD unit is covered
The HUD dimmer knob is adjusted incorrectly
The HUD image is not adjusted to the
proper height
Ambient light in the direction your vehicle is
facing, is low
A fuse is blown. SeeFuses and Circuit
Breakers on page 463.
Keep in mind that the windshield is part of the
HUD. SeeWindshield Replacement on page 404.
Ultrasonic Rear Parking
Assist (URPA)
The Ultrasonic Rear Parking Assist (URPA)
system is designed to help you park, while the
vehicle is in REVERSE (R). It operates only at very
low speeds, less than 3 mph (5 km/h). URPA
can help make parking easier and to help
you avoid colliding with objects such as parked
vehicles. The URPA system can detect objects up
to 5 feet (1.5 m) behind the vehicle, and tell
you how close these objects are from your rear
bumper.
Your vehicle’s URPA operates when the shift lever
is moved into REVERSE (R) and the vehicle
speed is less than 3 mph (5 km/h). Four ultrasonic
sensors located at the rear bumper are used to
detect the distance to the object. The URPA
display is located inside the vehicle, near the rear
window. It has three color-coded lights used to
provide distance and system information to
the driver.

Retro-Active Reset
The trip odometer has a feature called retro-active
reset. This feature can be used to set the trip
odometer to the number of miles or kilometers
driven since the ignition was last turned on. This
can be used if you forget to reset your trip odometer
at the beginning of a trip. To use the retro-active
reset feature, push and hold the trip/reset button for
at least ve seconds. The trip odometer will then
display the number of miles or kilometers driven
since the ignition was last turned on and you began
driving. If you use the retro-active reset feature after
you have started the vehicle, but before you begin
moving, the display will show the number of miles
or kilometers you drove during the last ignition
cycle. Once you begin driving, the trip odometer will
accumulate mileage. For example, if you have
driven 5.0 miles (8.0 km) since you started your
vehicle, and then activate the retro-active reset
feature, the display will show 5.0 miles (8.0 km). As
you drive, the display will then increase to 5.1 miles
(8.2 km), 5.2 miles (8.4 km), etc.
Tachometer
The tachometer displays
the engine speed in
revolutions per
minute (rpm).

Safety Belt Reminder Light
When the key is turned to ON or START, a chime
will come on for several seconds to remind
people to fasten their safety belts.
The safety belt light will
also come on and stay
on for several
seconds, then it will
ash for several more.
If the driver remains unbuckled when the ignition
is on and the vehicle is in motion, the chime
and the safety belt light will be repeated. You
should buckle your safety belt. If the driver’s belt
is already buckled, neither the chime nor the
light will come on.
Airbag Readiness Light
There is an airbag readiness light on the
instrument panel, which shows the airbag symbol.
The system checks the airbag’s electrical
system for malfunctions. The light tells you if there
is an electrical problem. The system check
includes the airbag sensor, the airbag modules,
the wiring, diagnostic module, and safety belt
pretensioners. For more information on the airbag
system, seeAirbag System on page 88. For
more information on safety belt pretensioners, see
Safety Belt Pretensioners on page 56.
215

This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should go
out. This means the
system is ready.
If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system or safety belt pretensioners
may not work properly. Have your vehicle serviced
right away.
{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays on
after you start your vehicle.
The airbag readiness light should ash for a few
seconds when you turn the ignition key to ON.
If the light does not come on then, have it xed so
it will be ready to warn you if there is a problem.
216

Passenger Airbag Status Indicator
Your vehicle has the passenger sensing system.
Your rearview mirror has a passenger airbag
status indicator.
When the ignition key is turned to ON or START,
the passenger airbag status indicator will light
ON and OFF, or the symbol for on and off,
for several seconds as a system check. Then,
after several more seconds, the status indicatorwill light either ON or OFF, or either the on or off
symbol to let you know the status of the right
front passenger’s frontal airbag.
If the word ON or the on symbol is lit on the
passenger airbag status indicator, it means that
the right front passenger’s frontal airbag is enabled
(may inate).
{CAUTION:
If the on indicator comes on when you have
a rear-facing child restraint installed in the
right front passenger’s seat, it means that
the passenger sensing system has not
turned off the passenger’s frontal airbag.
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag. Do not use a rear-facing
child restraint in the right front passenger’s
seat if the airbag is turned on.United States

Brake System Warning Light
When the ignition is on, the brake system warning
light will come on when you set your parking
brake. The light will stay on if your parking brake
does not release fully. If it stays on after your
parking brake is fully released, it means you have
a brake problem.
Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not working, the other
part can still work and stop you. For good
braking, though, you need both parts working well.
If the warning light comes on, there could be a
brake problem. Have your brake system inspected
right away.This light should come on briey when you turn
the ignition key to ON. If it does not come on then,
have it xed so it will be ready to warn you if
there is a problem.
If the light comes on while you are driving, pull off
the road and stop carefully. You may notice
that the pedal is harder to push, or the pedal may
go closer to the oor. It may take longer to
stop. If the light is still on, have the vehicle towed
for service. SeeAnti-Lock Brake System
Warning Light on page 220andTowing Your
Vehicle on page 337.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light
is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.

Anti-Lock Brake System
Warning Light
Your vehicle may have an Anti-Lock Brake System
(ABS) warning light. If it does, the light should come
on for a few seconds when you turn the ignition key
to ON. If the ABS warning light stays on longer than
normal after you have started your engine, turn the
ignition off. If the light comes on and stays on when
you are driving, stop as soon as possible and turn
the ignition off. Then start the engine again to reset
the system. If the light still stays on, or comes on
again while you are driving, the ABS needs service
and you do not have anti-lock brakes.The ABS warning light should come on briey
when you turn the ignition key to ON. If the light
does not come on then, have it xed so it will
be ready to warn you if there is a problem.

Malfunction Indicator Lamp
Service Engine Soon Light in the
United States or Check Engine Light in
Canada
Your vehicle has a computer which monitors
operation of the fuel, ignition, and emission control
systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable
levels for the life of the vehicle, helping to produce
a cleaner environment. The SERVICE ENGINE
SOON or check engine light comes on to indicate
that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This mayprevent more serious damage to your vehicle.
This system is also designed to assist your service
technician in correctly diagnosing any malfunction.
Notice:If you keep driving your vehicle
with this light on, after awhile, your emission
controls may not work as well, your fuel
economy may not be as good, and your engine
may not run as smoothly. This could lead to
costly repairs that may not be covered by your
warranty.
Notice:Modications made to the engine,
transaxle, exhaust, intake, or fuel system
of your vehicle or the replacement of the
original tires with other than those of the same
Tire Performance Criteria (TPC) can affect
your vehicle’s emission controls and may
cause this light to come on. Modications to
these systems could lead to costly repairs not
covered by your warranty. This may also
result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 354.

This light should come on, as a check to show
you it is working, when the ignition is on and the
engine is not running. If the light does not
come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and may damage the emission
control system on your vehicle. Diagnosis and
service may be required.
Light On Steady— An emission control
system malfunction has been detected on your
vehicle. Diagnosis and service may be
required.
If the Light Is Flashing
The following may prevent more serious damage
to your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possibleIf the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, when it is safe to do
so, stop the vehicle. Find a safe place to park
your vehicle. Turn the key off, wait at least
10 seconds and restart the engine. If the light
remains on steady, see “If the Light Is On Steady”
following. If the light is still ashing, follow the
previous steps, and see your dealer for service as
soon as possible.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. SeeFilling the Tank on page 359.
The diagnostic system can determine if the
fuel cap has been left off or improperly installed.
A loose or missing fuel cap will allow fuel to
evaporate into the atmosphere. A few driving trips
with the cap properly installed should turn the
light off.
