Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briey when the engine is
started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
If the ABS light stays on, turn the ignition off. If the light
comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on, or
comes on again while driving, the vehicle needs service.
If the regular brake system warning light is not on, the
vehicle still has brakes, but not antilock brakes. If the
regular brake system warning light is also on, the vehicle
does not have antilock brakes and there is a problem with
the regular brakes. SeeBrake System Warning Light on
page 3-33.
For vehicles with a Driver Information Center (DIC), see
DIC Warnings and Messages on page 3-50for all
brake related DIC messages.
Enhanced Traction System (ETS)
Indicator/Warning Light
For vehicles with the
Enhanced Traction System
(ETS), this light serves
as an indicator and
warning light.
This light comes on briey while the engine is started.
If it does not, have the vehicle serviced by your dealer/
retailer. If the system is working normally the indicator
light then goes off.
If the indicator/warning light is on and not ashing, the
ETS system could have been disabled. Check all related
Driver Information Center (DIC) messages to determine
whether the system has been turned off or if the system
is not working properly and the vehicle requires service.
If the ETS has been disabled, wheel spin is not limited.
If the indicator/warning light is on and ashing, the ETS
is actively working. The LOW TRACTION DIC message
also appears when the system is actively limiting
wheel spin.

Electronic Stability Control (ESC)/
Traction Control System (TCS)
Indicator/Warning Light
The Electronic Stability
Control (ESC) system
or the Traction Control
System (TCS) indicator/
warning light comes on
briey when the engine is
started.
If it does not, have the vehicle serviced by the
dealer/retailer. If the system is working normally the
indicator light goes off.
This light, along with the appropriate Driver Information
Center (DIC) messages, indicates when the ESC
system and the TCS are working or are disabled.If the light comes on and stays on, the TCS and
potentially the ESC system have been disabled.
Check the DIC messaging to determine which system is
turned off, or not working. If the system is not working,
the vehicle needs service. See your dealer/retailer.
When the TCS is disabled, wheel spin is not limited.
When the ESC system is disabled, the system does not
aid in maintaining vehicle directional control.
If the light comes on and ashes, the TCS or the ESC
system is actively working. When the LOW TRACTION
message appears, the system is limiting wheel spin.
When the ESC ACTIVE message appears, the system
is aiding in maintaining vehicle directional control.

Engine Coolant Temperature
Warning Light
This light comes on briey
while starting the vehicle.
If it does not, have the vehicle serviced by the
dealer/retailer. If the system is working normally the
indicator light goes off.
Notice:Driving with the engine coolant temperature
warning light on could cause the vehicle to overheat.
SeeEngine Overheating on page 5-32. The vehicle’s
engine could be damaged, and it might not be
covered by the vehicle warranty. Never drive with
the engine coolant temperature warning light on.
The engine coolant temperature warning light comes on
when the engine has overheated.
If this happens pull over and turn off the engine as soon
as possible. SeeEngine Overheating on page 5-32
for more information.
Engine Coolant Temperature Gage
The vehicle has 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 because the engine coolant has overheated.
If the vehicle is 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 5-32.
3-36

This light should come 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. 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: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. See
Accessories 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.
To 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.
3-38

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 5-9. 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 can 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, your
dealer/retailer can 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.

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 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
{CAUTION:
Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches re.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice:Lack of proper engine oil maintenance
can damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.

This light comes on briey while starting the engine.
If it does not, have the vehicle serviced by your dealer/
retailer. If the system is working normally the indicator
light then goes off.
If the light comes on and stays on, it means that oil is
not owing through the engine properly. The vehicle
could be low on oil and it might have some other system
problem.
Security Light
For information regarding
this light and the vehicle’s
security system, see
Content Theft-Deterrent on
page 2-19.
Fog Lamp Light
The fog lamp light comes
on when the fog lamps are
in use.
The light goes out when the fog lamps are turned off.
SeeFog Lamps on page 3-16for more information.
Highbeam On Light
This light comes on when
the high-beam headlamps
are in use.
SeeHeadlamp High/Low-Beam Changer on page 3-8
for more information.

Fuel Gage
The fuel gage indicates
about how much fuel is left
in the fuel tank.
An arrow on the fuel gage indicates the side of the
vehicle the fuel door is on.
Here are four things that some owners ask about. None
of these show a problem with the fuel gage:
At the service station, the gas pump shuts off
before the gage reads full.
It takes a little more or less fuel to ll up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the fuel tank’s capacity
to ll it.
The gage moves a little when the vehicle turns a
corner or speeds up.
The gage does not go back to empty when the
ignition is turned off.
For the fuel tank capacity, seeCapacities and
Specifications on page 5-114.
Boost Gage
For vehicles with this gage, it indicates vacuum during
light to moderate throttle and boost under heavier
throttle.
