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 3-47.
For vehicles with a Driver Information Center (DIC),
seeDIC Warnings and Messages on page 3-60for all
brake related DIC messages.
StabiliTrak®/Traction Control
System (TCS) Warning Light
The Traction Control
System (TCS)/StabiliTrak
system warning light
comes on briey as the
engine is started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator lights go off.
If the light stays on, or comes on while driving and
the DIC shows a SERVICE TRACTION SYS or
a SERVICE STABILITRAK message, there is a
problem with the Traction Control System (TCS)
or the StabiliTrak
®system and the vehicle needs
service.

Tire Pressure Light
For vehicles with the tire
pressure light, it 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.
This light also comes on when 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 3-60for more
information.
Stop and check the tires as soon as it is safe to do so.
If underinated, inate the tire to the proper pressure.
SeeTires on page 6-46for more information.
If a problem is detected with the Tire Pressure Monitor
System, this light ashes for approximately 60 seconds
and then stays on for the remainder of the ignition
cycle. SeeTire Pressure Monitor System on page 6-55
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 makes
sure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment.
This comes on briey
while starting the engine.
If it does not come on,
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.
3-50

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 6-3.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.
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.

an advanced, computer-controlled system has come on
to help the vehicle continue to go in the direction in
which you are steering. This stability enhancement
system activates when the computer senses that the
vehicle is just starting to spin, as it might if you hit
a patch of ice or other slippery spot on the road.
