Outlet Adjustment
Use the lever located in the center of each outlet to
change the direction of the airflow, either side-to-side or
up and down. Use the thumbwheels to open or close
the outlets to adjust the airflow.
Turn the thumbwheel towards the vehicle door to open
the outlets and allow the maximum amount of air to
enter your vehicle. Turn the thumbwheel towards the
center console to close the outlets and minimize the
amount of air entering the vehicle.
Operation Tips
.Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may block
the flow of air into your vehicle.
.Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
.Keep the path under the front seats clear of
objects to help circulate the air inside of your
vehicle more effectively.
.If the airflow seems low when the fan speed is at
the highest setting, the passenger compartment
air filter may need to be replaced. For more
information, seePassenger Compartment Air
Filter on page 4‑50.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments may have
programs to inspect the on-vehicle emission control
equipment For the inspection, the emission system test
equipment is connected to the vehicle’s Data Link
Connector (DLC).
The DLC is under the instrument panel to the left of the
steering wheel. See your dealer if assistance is needed.The vehicle may not pass inspection if:
.the Malfunction Indicator Lamp is on with the
engine running, or if the light does not come on
when the ignition is turned to ON/RUN while the
engine is off.
.the critical emission control systems have not been
completely diagnosed by the system. This can
happen if the battery has recently been replaced or
if the battery has run down. The diagnostic system
evaluates 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, your
dealer can prepare the vehicle for inspection.

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.
