If, after several seconds, both status indicator lights
remain on, or if there are no lights at all, there may
be a problem with the lights or the passenger sensing
system. See your dealer for service.
{WARNING:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on, it
means that something may be wrong with the
airbag system. If this ever happens, have the
vehicle serviced promptly, because an adult-size
person sitting in the right front passenger's seat
may not have the protection of the airbag(s). See
Airbag Readiness Light
on page 4‑54for more
on this, including important safety information.
Charging System Light
This light comes on briefly
when the ignition key is
turned to START, 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.
The light should go out once the engine starts. If it stays
on, or comes on while driving, there could be a problem
with the charging system. A charging system message
in the Driver Information Center (DIC) can also appear.
See DIC Warnings and Messages
on page 4‑76for
more information. This light could indicate that there are
problems with a generator drive belt, or that there is an
electrical problem. Have it checked right away. If the
vehicle must be driven a short distance with the light
on, turn off accessories, such as the radio and air
conditioner.

Driver Information Center (DIC)
The Driver Information Center (DIC) gives you the
status of many of your vehicle's systems. The DIC is
also used to display warning/status messages. All
messages will appear in the DIC display located at
the bottom of the instrument panel cluster, below the
tachometer and speedometer. The DIC buttons are
located on the instrument panel, to the left of the
steering wheel.
The DIC comes on when the ignition is on. After a short
delay, the DIC will display the current driver and the
information that was last displayed before the engine
was turned off.
The top line of the DIC display shows the vehicle
system information and the warning/status messages.
The bottom line of the DIC display shows either the
odometer, the trip odometer A or the trip odometer B
information on the left side. Only one odometer can
appear at a time. See“Trip Information”underDIC
Operation and Displays
on page 4‑70for information on changing the display to show the odometer or trip
odometer information. The bottom line of the DIC
display also shows the outside temperature on the
right side and the shift lever position indicator in the
center. See
Automatic Transmission Operation
on
page 3‑30for more information on the shift lever
positions.
When the sport mode is active, an S will appear next
to the shift position indicator on the center of the DIC
display. When the manual mode is active, an M will
appear on the DIC display. When the normal mode is
active, only the shift position indicator will appear. While
the Driver Shift Control (DSC) feature is active, the DIC
will change to show the selected gear. See “Driver Shift
Control (DSC)” underAutomatic Transmission
Operation
on page 3‑30for more information.
If a problem is detected, a warning message will appear
on the display. Be sure to take any message that
appears on the display seriously and remember that
clearing the message will only make the message
disappear, not correct the problem.

Tire Pressure Monitor Operation
This vehicle may have a Tire Pressure Monitor System
(TPMS). The TPMS is designed to warn the driver when
a low tire pressure condition exists. TPMS sensors are
mounted onto each tire and wheel assembly, excluding
the spare tire and wheel assembly, if the vehicle has
one. The TPMS sensors monitor the air pressure in the
vehicle's tires and transmits the tire pressure readings
to a receiver located in the vehicle.
When a low tire pressure
condition is detected, the
TPMS illuminates the low
tire pressure warning light
located on the instrument
panel cluster.
If the warning light comes on, stop as soon as possible
and inflate the tires to the recommended pressure
shown on the tire loading information label. See
Loading the Vehicle on page 5‑23.
At the same time a message to check the pressure in a
specific tire appears on the Driver Information Center
(DIC) display. The low tire pressure warning light and
the DIC warning message come on at each ignition
cycle until the tires are inflated to the correct inflation
pressure. Using the DIC, tire pressure levels can be viewed by the driver. For additional information and
details about the DIC operation and displays see
DIC
Operation and Displays
on page 4‑70and DIC
Warnings and Messages on page 4‑76.
The low tire pressure warning light may come on in cool
weather when the vehicle is first started, and then turn
off as you start to drive. This could be an early indicator
that the air pressure in the tire(s) are getting low and
need to be inflated 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 inflation pressure for
your vehicle's tires when they are cold. See Loading the
Vehicle
on page 5‑23for an example of the Tire and
Loading Information label and its location on your
vehicle. Also see Inflation - Tire Pressure
on
page 6‑58.
Your vehicle's TPMS can warn you about a low tire
pressure condition but it does not replace normal tire
maintenance. See Tire Inspection and Rotation
on
page 6‑65and Tires on page 6‑50.
Notice: Using non‐approved tire sealants could
damage the Tire Pressure Monitor System (TPMS)
sensors. TPMS sensor damage caused by using an
incorrect tire sealant is not covered by the vehicle
warranty. Always use the GM approved tire sealant
available through your dealer.
