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 may be or is a
problem with one of the vehicle’s functions. Some
warning lights come on briey when the engine is started
to indicate they are working.
Gages can indicate when there may be or 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
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.
3-23

Speedometer and Odometer
The speedometer shows the vehicle’s speed in both
miles per hour (mph) and kilometers per hour (km/h).
The odometer shows how far the vehicle has been
driven, in either miles (used in the United States)
or kilometers (used in Canada).
Trip Odometer
The trip odometer can record the number of miles, used
in the United States, or kilometers, used in Canada,
traveled for up to two trips.

comes on and stays on
for several seconds to
remind the people to
fasten their safety belts.
The light also begins
to ash.
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 comes on.
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, seeAirbag System on page 1-58.This light comes on when
the vehicle is started,
and it will ash for a

Charging System Light
This light will come on briey 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.

For vehicles with the
Antilock Brake System
(ABS), this light comes on
briey 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.
SeeBrake System Warning Light on page 3-28.
The ABS warning light will come on briey when the
ignition is turned to ON/RUN. This is normal. If the light
does not come on then, have it xed 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 ashes, have the vehicle checked.
See “Hold Mode” underAutomatic Transmission
Operation on page 2-20for more information.
Engine Coolant Temperature Gage
The vehicle may have an engine coolant temperature
gage. With the ignition turned to ON/RUN, this gage
shows the engine coolant temperature.
United StatesCanada
3-30

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.
SeeEngine Overheating on page 5-28.
Tire Pressure Light
For vehicles with the tire
pressure light, it comes on
briey 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
signicantly underinated.
Stop and check the tires as soon as it is safe to do,
and inate them to the proper pressure. SeeTires on
page 5-50for more information.
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 ashes
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 5-58for more information.
3-31

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:Modications 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.
Modications 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.
SeeAccessories and Modifications on page 5-3.
This light comes on during a malfunction in one of
two ways:
Light Flashing:A misre condition has been detected.
A misre increases vehicle emissions and could
damage the emission control system on the vehicle.
Diagnosis and service might be required.
3-32

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 ash, 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 ashing, 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. SeeFilling
the Tank on page 5-8. 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, misring, 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.
SeeGasoline Octane on page 5-5.
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
x any mechanical or electrical problems that might have
developed.
