Traction Control System (TCS)
Warning Light
Your vehicle has a
Traction Control System
(TCS) and StabiliTrak
®
warning light.
When the traction control is activated the light will
ash when the TCS is limiting wheel spin or when the
StabiliTrak
®system is active. You may feel or hear the
system working, but this is normal. This light may also
come on after extended heavy braking indicating the
brakes have become too hot to limit wheel spin.
This light will come on and stay on if the TCS is turned
off using the traction control on/off button, located
next to the gear shift lever.
If the TCS warning light comes on and stays on for an
extended period of time when the system is turned on,
your vehicle needs service. SeeTraction Control System
(TCS) on page 4-7andStabiliTrak
®System on page 4-6
for more information.
Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning light
will come on when the
engine has overheated.
If this happens you should pull over and turn off the
engine as soon as possible. SeeEngine Overheating
on page 5-28for more information.
Notice:Driving with the engine coolant temperature
warning light on could cause the vehicle to overheat.
SeeEngine Overheating on page 5-28. 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.

Engine Coolant Temperature Gage
This gage measures
the temperature of the
vehicle’s engine coolant.
If the indicator needle moves towards the shaded in
thermostat, the engine is too hot. The engine coolant
temperature warning light will turn on. SeeEngine
Coolant Temperature Warning Light on page 3-32
for more information.
If you have been operating your vehicle under normal
driving conditions, and the engine coolant temperature
warning light comes on, you should pull off the road,
stop your vehicle and turn off the engine as soon
as possible.
Tire Pressure Light
For vehicles with a tire
pressure monitoring
system, this light 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 is signicantly
underinated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. SeeDIC
Warnings and Messages on page 3-49for more
information. Stop and check the tires as soon as it is
safe to do so. If a tire is underinated, inate to the
proper pressure. SeeTires on page 5-48for more
information.
3-33

When the Light Flashes First and Then is
On Steady
This indicates that there could be a problem with the
Tire Pressure Monitor System. The light ashes for about
a minute and stays on steady for the remainder of the
ignition cycle. This sequence repeats with every ignition
cycle. SeeTire Pressure Monitor System on page 5-57
for 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 ensures that emissions are at acceptable levels
for the life of the vehicle, helping to produce a cleaner
environment.
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. SeeAccessories and Modifications on page 5-3.
3-34

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.
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 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 (US-Canada)
{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.

Fuel Gage
When the ignition is on,
the fuel gage tells you
about how much fuel you
have left in your tank.
When the indicator nears empty, the low fuel light will
come on. You still have a little fuel left, but you should get
more soon. SeeLow Fuel Warning Light on page 3-41for
more information.
Here are four things that some owners ask about.
None of these show a problem with your fuel gage:
At the service station, the fuel 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 tank’s capacity
to ll the tank.
The gage moves a little when you turn a corner or
speed up.
The gage takes a few seconds to stabilize after the
ignition is turned on, and will go back to empty
when you turn the ignition off.
For your fuel tank capacity, seeCapacities and
Specifications on page 5-97.
Low Fuel Warning Light
This light is located in
the fuel gage. For more
information seeFuel Gage
on page 3-41.
This light comes on when the fuel tank is low on fuel.
When you add fuel the light should go off. If it does not,
have your vehicle serviced.
A “Fuel Level LOW” message also appears in the Driver
Information Center (DIC). SeeFuel Gage on page 3-41
for more information.
