Warning Lights, Gages, and
Indicators
Warning lights and gages 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 gages could prevent injury.
Warning lights come on when there might be or there is
a problem with one of the vehicle's functions. Some
warning lights come on briefly when the engine is
started to indicate they are working.
Gages can indicate when there might be or there is a
problem with one of the vehicle's functions. Often gages
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 gages shows there
could 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.

Safety Belt Reminders
Driver Safety Belt Reminder Light
When the engine is started, a chime sounds for several
seconds to remind a driver to fasten the safety belt,
unless the driver safety belt is already buckled.
The safety belt light
comes on and stays on
for several seconds, then
flashes for several more.
This chime and light are repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver
safety belt is already buckled, neither the chime nor the
light comes on.
Passenger Safety Belt Reminder Light
For vehicles equipped with the passenger safety belt
reminder light, several seconds after the engine is
started, a chime sounds for several seconds to remind
the front passenger to buckle their safety belt. The
passenger safety belt light, located on the instrument
panel, comes on and stays on for several seconds and
then flashes for several more.
This chime and light are
repeated if the passenger
remains unbuckled and
the vehicle is in motion.
If the passenger safety belt is buckled, neither the
chime nor the light comes on.
The front passenger safety belt warning light and chime
may turn on if an object is put on the seat such as a
briefcase, handbag, grocery 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 tells if there is an electrical
problem. The system check includes the airbag sensor,
the airbag modules, the wiring and the crash sensing
and diagnostic module. For more information on the
airbag system, see Airbag System on page 2‑57.
4-23

This light comes on
when the vehicle is
started, and it will flash
for a few seconds. When
the light goes out this
indicates the system is
functioning properly.
If the airbag readiness light stays on 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.
Passenger Airbag Status Indicator
The vehicle has the passenger sensing system. See
Passenger Sensing Systemon page 2‑65for important
safety information. The vehicle has a passenger airbag
status indicator near the clock, located in the center of
the instrument panel.
United StatesCanada
When the vehicle is started, the passenger airbag
status indicator will light PASSENGER AIRBAG ON and
PASSENGER AIRBAG 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 PASSENGER AIRBAG ON or PASSENGER
AIRBAG OFF, or either the on or off symbol, to let you
know the status of the right front passenger frontal and
seat-mounted side impact airbag (if equipped).
4-24

If the words PASSENGER AIRBAG ON or the on
symbol is lit on the passenger airbag status indicator, it
means that the right front passenger frontal airbag and
seat-mounted side impact airbag (if equipped) is
enabled (may inflate).
If the words PASSENGER AIRBAG OFF or the off
symbol is lit on the passenger airbag status indicator, it
means that the passenger sensing system has turned
off the right front passenger frontal airbag and
seat-mounted side impact airbag (if equipped).
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/retailer 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. SeeAirbag Readiness Light
on page 4‑23
for more information, including important safety
information.
Charging System Light
This light will come on briefly when the ignition is turned
on, and the engine is not running, as a check to show it
is working.
It should go out when the engine is started. If it stays
on, or comes on while driving, there may have a
problem with the electrical charging system. Have it
checked by your dealer/retailer. Driving while this light is
on could drain the battery. If a short distance must be
driven with the light on, turn off all accessories, such as
the radio and air conditioner to help reduce the drain on
the battery.
4-25

Up-Shift Light
The vehicle may have an
up-shift light.
When this light comes on, shift to the next higher gear if
weather, road, and traffic conditions allow.
See Manual Transmission Operation
on page 3‑26for
more information.
Brake System Warning Light
The vehicle's hydraulic brake system is divided into two
parts. If one part is not working, the other part can still
work and stop the vehicle. For good braking, both parts
need to work.
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.
United StatesCanada
{WARNING:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service.
This light should come on briefly when the ignition is
turned to ON. If it does not come on then, have it fixed
so it will be ready to warn if there is a problem.
4-26

When the ignition is on, the brake system warning light
will also come on when the parking brake is set. The
light will stay on if the parking brake does not fully
release. If it stays on after the parking brake is fully
released, it means there is a brake problem.
If the light comes on while driving, carefully pull off the
road and stop. The pedal may be harder to push or may
go closer to the floor. It may take longer to stop. If the
light is still on, have the vehicle towed for service.
SeeTowing Your Vehicle on page 5‑25.
Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briefly when the engine is
started.
If the light stays on, turn the ignition to LOCK/OFF or if
the light comes on, 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 driving, the vehicle needs service. See your
dealer/retailer. If the regular brake system warning light
is not on, the brakes will still work, but the antilock
brakes will not work. If the regular brake system
warning light is also on, the antilock brakes will not
work and there is a problem with the regular brakes.
See
Brake System Warning Light on page 4‑26.
The ABS warning light will come on briefly when the
ignition is turned to ON/RUN. This is normal. If the light
does not come on then, have it fixed so it will be ready
to warn if there is a problem.
Hold Mode Light
If the vehicle has this
feature, this light comes
on when the hold mode
is active.
If the HOLD mode light flashes, have the vehicle
checked. See “Hold Mode”underAutomatic
Transmission Operation
on page 3‑22for more
information.
4-27

Engine Coolant Temperature Gage
United StatesCanada
The vehicle may have an engine coolant temperature
gage. With the ignition turned to ON/RUN, this gage
shows the engine coolant temperature.
If the gage pointer moves into the red area, 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 the vehicle and turn off
the engine as soon as possible.
See Engine Overheating on page 6‑30.
Tire Pressure Light
For vehicles with the tire
pressure monitoring
system, this light comes
on briefly when the engine
is started.
It provides information about tire pressures and the
Tire Pressure Monitoring System.
When the Light is On Steady
This indicates that one or more of the tires are
significantly underinflated.
Stop and check the tires as soon as it is safe to do,
and inflate them to the proper pressure. See Tires
on
page 6‑50for more information.
4-28

When the Light Flashes First and Then is
On Steady
This indicates that there may be a problem with the Tire
Pressure Monitor System. The light flashes for about a
minute and then stays on steady for the remainder of
the ignition cycle. This sequence will repeat with every
ignition cycle. SeeTire Pressure Monitor System
on
page 6‑58for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation
of the fuel, ignition, and emission control systems.
It makes sure 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/retailer. 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. Heeding 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 6‑3.
4-29

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 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/retailer 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 by
doing the following:
.Make sure the fuel cap is fully installed. See Filling
the Tankon page 6‑8. 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
Gasoline Octane on page 6‑6.
If none of the above have made the light turn off, have
your dealer/retailer check the vehicle. The dealer/
retailer has the proper test equipment and diagnostic
tools to fix any mechanical or electrical problems that
might have developed.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this
inspection could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
.The vehicle will not pass this inspection if the
check engine light is on with the engine running,
or if the key is in the ON/RUN and the light is
not on.
.The vehicle will not pass this inspection if the
OBD II (on-board diagnostic) system determines
that critical emission control systems have not
been completely diagnosed by the system.
The vehicle would be considered not ready for
inspection. This can happen if the battery has
recently been replaced or if the battery has run
down. The diagnostic system is designed to
evaluate critical emission control systems during
normal driving. This can take several days of
routine driving. If this has been done and the
vehicle still does not pass the inspection for lack of
OBD II system readiness, your dealer/retailer can
prepare the vehicle for inspection.
Oil Pressure Light
If the vehicle has low
engine oil pressure, this
light will stay on after the
engine has been started,
or come on while driving.
This indicates that the engine is not receiving enough
oil. The engine could be low on oil, or could have some
other oil problem. Have it fixed immediately by your
dealer/retailer.
