3-34 Seats and Restraints
You can lock the doors, turn off the
interior lamps and hazard warning
flashers by using the controls for
those features.
{WARNING
A crash severe enough to
inflate the airbags may have
also damaged important functions
in the vehicle, such as the fuel
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.If damage to the vehicle is minor,
you may attempt to restart the
vehicle's engine. Note: If the fuel
system has been shut off after an
airbag has inflated, you may not
be able to restart the engine for up
to ten minutes. See
Starting the
Engineon page 9‑35for more
information.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation.
Additional windshield breakage
may also occur from the right front
passenger airbag.
.Airbags are designed to inflate
only once. After an airbag
inflates, you will need some
new parts for the airbag system.
If you do not get them, the
airbag system will not be there to help protect you in another
crash. A new system will include
airbag modules and possibly
other parts. The service manual
for your vehicle covers the need
to replace other parts.
.The vehicle has a crash sensing
and diagnostic module which
records information after a
crash. See
Vehicle Data
Recording and Privacy
on
page 13‑15and Event Data
Recorders on page 13‑15.
.Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.

Ashtrays
For vehicles with a removable
ashtray, it can be placed into the
cupholder and be removed for
cleaning.
Notice:If papers, pins, or other
flammable items are put in the
ashtray, hot cigarettes or other
smoking materials could ignite
them and possibly damage the
vehicle. Never put flammable
items in the 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.
Warning lights come on when there
could be a problem with a vehicle
function. Some warning lights come
on briefly when the engine is started
to indicate they are working. Gauges can indicate when there
could be a problem with a vehicle
function. Often gauges and warning
lights work together to indicate a
problem with the vehicle.
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. Follow this manual's advice.
Waiting to do repairs can be costly
and even dangerous.

5-8 Instruments and Controls
Speedometer
The speedometer shows the
vehicle's speed in both kilometers
per hour (km/h) and miles per
hour (mph).
Odometer
The odometer shows how far the
vehicle has been driven, in either
kilometers or miles.
This vehicle has a tamper-resistant
odometer. If the vehicle needs a
new odometer installed, the new
one is set to the mileage of the old
odometer. If this is not possible,
it is set at zero and a label is put
on the driver's door to show the old
mileage reading.
Trip Odometer
The vehicle has a trip odometer that
indicates how far the vehicle has
been driven since the trip odometer
was last set to zero.See
“Trip Odometer” underDriver
Information Center (DIC)
on
page 5‑18for more information.
Tachometer
The tachometer displays the engine
speed in revolutions per
minute (rpm).
Fuel Gauge
United StatesCanada
The fuel gauge indicates about how
much fuel there is remaining in the
fuel tank. The ignition must be in
ON/RUN.
An arrow on the fuel gauge
indicates the side of the vehicle
the fuel door is on. Here are three things that can
happen but do not indicate a
problem with the fuel gauge:
.At the gas station, the gas pump
shuts off before the gauge
reads full.
.It takes a little more or less
fuel to fill up than the gauge
indicated. For example, the
gauge may have indicated the
tank was half full, but it actually
took a little more or less than
half the tank's capacity to fill
the tank.
.The gauge moves a little when
turning a corner or speeding up.
When the fuel in the fuel tank is low,
a LOW FUEL message displays on
the Driver Information Center (DIC).
See Fuel System Messages
on
page 5‑24for more information.

Instruments and Controls 5-9
Engine Coolant
Temperature Gauge
United StatesCanada
This gauge shows the engine
coolant temperature.
If the gauge pointer is in the shaded
area of the gauge, the engine is
too hot. It means that the engine
coolant has overheated. If the
vehicle has been operating under
normal driving conditions, pull off
the road, stop your vehicle and turn
off the engine as soon as possible.
See Engine Overheating
on
page 10‑22for more information.
Safety Belt Reminders
Driver Safety Belt Reminder
Light
There is a driver safety belt
reminder light on the instrument
panel cluster.
When the engine is started this
light and a chime come on and stay
on for several seconds to remind
drivers to fasten their safety belts.
The light also begins to flash.
This cycle repeats if the driver
remains unbuckled and the vehicle
is moving.
If the driver safety belt is already
buckled, neither the light nor chime
come on.
Passenger Safety Belt
Reminder Light
The passenger safety belt reminder
light is by the passenger airbag
status indicator.
When the engine is started this light
and the chime come on and stay on
for several seconds to remind the
passenger to fasten their safety belt.
The light also begins to flash.
This cycle repeats if the passenger
remains unbuckled and the vehicle

bag, laptop or other electronic
device. To turn off the warning light
and or chime, remove the object
from the seat or buckle the
safety belt.
Airbag Readiness Light
There is an airbag readiness light
on the instrument panel cluster,
which shows the airbag symbol.
The system checks the airbag's
electrical system for malfunctions.
The light indicates if there is an
electrical problem. The system
check includes the airbag sensor,
the pretensioners, the airbagmodules, the wiring and the crash
sensing and diagnostic module.
For more information on the airbag
system, see
Airbag System
on
page 3‑27.
This light comes on when the
vehicle is started, and flashes for a
few seconds. The light goes out
when the system is ready.
If the airbag readiness light stays on
after the vehicle is started or comes
on while driving, the airbag system
may not work properly. Have the
vehicle serviced right away.
{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.
The airbag readiness light should
flash for a few seconds when the
engine is started. If the light does
not come on then, have it fixed
immediately.

Instruments and Controls 5-11
Passenger Airbag Status
Indicator
The vehicle has the passenger
sensing system. SeePassenger
Sensing System
on page 3‑35for
important safety information. The
instrument panel has a passenger
airbag status indicator.
United States
Canada
When the vehicle is started, 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
indicator will light either ON or OFF,
or either the on or off symbol to let
you know the status of the right front
passenger 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 frontal airbag is
enabled (may inflate).
If the word OFF or the off symbol is
lit on the airbag status indicator, it
means that the passenger sensing
system has turned off the right front
passenger frontal airbag.
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be
a problem with the lights or the
passenger sensing system. See
your dealer for service.
{WARNING
If the airbag readiness light
ever comes on and stays on, it
means that something may be
wrong with the airbag system.
To help avoid injury to yourself or
others, have the vehicle serviced
right away. See
Airbag Readiness
Light
on page 5‑10for more
information, including important
safety information.
Charging System Light
This light comes on briefly when the
ignition key is turned, but the engine
is not running, as a check to show it
is working.

5-12 Instruments and Controls
It should go out once the engine
starts. If it stays on, or comes on
while driving, there could be a
problem with the charging system.
A charging system message in the
Driver Information Center (DIC)
may also appear. SeeBattery
Voltage and Charging Messages
on
page 5‑21for more information.
This light could indicate that there
are problems with a generator drive
belt, or that there is an electrical
problem. Have it checked right
away. If the vehicle must be driven a
short distance with the light on, turn
off all the accessories, such as the
radio and air conditioner.
Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the fuel, ignition, and emission
control systems. It ensures that emissions are at acceptable levels
for the life of the vehicle, helping to
produce a cleaner environment.
This light comes on when the
ignition is on, but the engine is not
running, as a check to show it is
working. If it does not, have the
vehicle serviced by your dealer.
If the check engine light comes on
and stays on, while the engine is
running, this indicates that there is
an OBD II problem and service is
required.
Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system assists
the service technician in correctly
diagnosing any malfunction.Notice:
If the vehicle is
continually driven with this light
on, after a while, the emission
controls might not work as well,
the vehicle's fuel economy might
not be as good, and the engine
might not run as smoothly. This
could lead to costly repairs that
might not be covered by the
vehicle warranty.
Notice: Modifications made to the
engine, transmission, exhaust,
intake, or fuel system of the
vehicle or the replacement of
the original tires with other
than those of the same Tire
Performance Criteria (TPC) can
affect the vehicle's emission
controls and can cause this light
to come on. Modifications to
these systems could lead to
costly repairs not covered by
the vehicle warranty. This
could also result in a failure
to pass a required Emission
Inspection/Maintenance test.
See Accessories and
Modifications on page 10‑3.

Instruments and Controls 5-13
This light comes on during a
malfunction in one of two ways:
Light Flashing:A misfire condition
has been detected. A misfire
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
The following can prevent more
serious damage to the vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
.If towing a trailer, reduce the
amount of cargo being hauled as
soon as it is possible.
If the light continues to flash, when
it is safe to do so, stop the vehicle.
Find a safe place to park the
vehicle. Turn the key off, wait at
least 10 seconds, and restart the
engine. If the light is still flashing,
follow the previous steps and see
your dealer for service as soon as
possible. Light On Steady:
An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required.
An emission system malfunction
might be corrected.
.Make sure the fuel cap is fully
installed. See Filling the Tankon
page 9‑68. The diagnostic
system can determine if the
fuel cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel to
evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn the
light off.
.If the vehicle has been driven
through a deep puddle of water,
the vehicle's electrical system
might be wet. The condition is
usually corrected when the
electrical system dries out.
A few driving trips should turn
the light off.
.Make sure to fuel the vehicle
with quality fuel. Poor fuel quality
causes the engine not to run as
efficiently as designed and may
cause: stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.
If one or more of these
conditions occurs, change the
fuel brand used. It will require at
least one full tank of the proper
fuel to turn the light off.
See Recommended Fuel
on
page 9‑64.
If none of the above have made
the light turn off, your dealer can
check the vehicle. The dealer
has the proper test equipment
and diagnostic tools to fix any
mechanical or electrical problems
that might have developed.
