vehicle. The vehicle usually restarts; however, you may
want to take the vehicle to your GM dealer before
turning off the engine. SeePASS-Key
®III+ Operation
on page 2-16for more information.
SERVICE TIRE MONITOR SYSTEM
If your vehicle has a Tire Pressure Monitor (TPM)
system, this message will display if a part on the system
is not working properly. If you drive your vehicle while
any of the four sensors are missing or inoperable,
the warning will come on in about 10 minutes. A sensor
would be missing, for example, if you put different
wheels on your vehicle without transferring the sensors.
If the warning comes on and stays on, there may be
a problem with the TPM. See your GM dealer.
SERVICE TRACTION CONTROL
If your vehicle has the traction control system, this
message will display when the system is not functioning
properly. A warning light will also appear on the
instrument panel cluster. SeeTraction Control System
(TCS) Warning Light on page 3-32. SeeTraction Control
System (TCS) on page 4-9for more information. Have
the traction control system serviced by your GM dealer as
soon as possible.
SERVICE TRANSMISSION
This message will display when there is a problem with

Anti-Lock Brake System (ABS)
Your vehicle may have the Anti-Lock Brake System
(ABS), an advanced electronic braking system that will
help prevent a braking skid.
If your vehicle has ABS,
this warning light on the
instrument panel
cluster will come on brie y
when you start your
vehicle.
When you start your engine, or when you begin to drive
away, ABS will check itself. You may hear a momentary
motor or clicking noise while this test is going on,
and you may even notice that your brake pedal moves
or pulses a little. This is normal.Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each front wheel
and at both rear wheels.

When a low tire pressure condition is detected, the
TPMS will illuminate the low tire pressure warning
symbol on the instrument panel cluster, and at the same
time a message to check the pressure in a speci c
tire will appear on the Driver Information Center (DIC)
display. The low tire pressure warning symbol on
the instrument panel cluster and the check tire pressure
message will appear at each ignition cycle until the
tires are in ated to the correct in ation pressure. Using
the DIC, tire pressure levels can be viewed by the
driver. For additional information and details about the
DIC operation and displays seeDIC Operation and
Displays on page 3-40andDIC Warnings and Messages
on page 3-46.
The tire pressure warning light may come on in cool
weather when the vehicle is rst started, and then
turn off as you start to drive. This may be an early
indicator that the air pressure in the tire(s) are getting
low and need to be in ated to the proper pressure.
A tire and Loading Information label, attached to your
vehicle, shows the size of your vehicle’s original
equipment tires and the correct in ation pressure for
your vehicle’s tires when they are cold. SeeLoading
Your Vehicle on page 4-29, for an example of the
tire information label and its location on your vehicle.
Also seeIn ation - Tire Pressure on page 5-60.Your vehicle’s TPMS system can warn you about a low
tire pressure condition but it does not replace normal
tire maintenance. SeeTire Inspection and Rotation
on page 5-66andTires on page 5-54.
Notice:Do not use a tire sealant if your vehicle
has Tire Pressure Monitors. The liquid sealant can
damage the tire pressure monitor sensors.
The TPMS will not function properly if one or more of
the TPMS sensors are missing or inoperable. If the
system detects a missing or inoperable sensor, an error
message SERVICE TIRE MONITOR SYSTEM will be
shown on the DIC display. If you have replaced a
tire/wheel assembly without transferring the TPMS
sensors, the error message will be displayed. Once
you re-install the TPMS sensors, the error message
should go off. See your GM dealer for service if
all TPMS sensors are installed and the error message
comes on and stays on.
