2008 CHEVROLET TRAIL BLAZER instrument panel

There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running
Lamps (DRL) and the automatic headlamp systems,
so that driving under bridges or bright overhead street
lights does not affect the system. The DRL and
automatic headlamp system are only affected when the
light sensor sees a change in lighting lasting longer
than the delay.
If you start your vehicle in a dark garage, the automatic
headlamp system comes on after the transmission is
shifted out of PARK (P). Once you leave the garage, it
will take about one minute for the automatic headlamp
system to change to DRL if it is light outside. During that
delay, the instrument panel cluster might not be as
bright as usual. Make sure the instrument panel
brightness control is in the full bright position.
If the vehicle is running and the automatic headlamp
system is already on, it can be turned off by turning and
releasing the headlamp control at the off position.
The automatic headlamp system stays off until you turn
and release the headlamp control at the off position
again. SeeHeadlamps on page 3-14.Fog Lamps
Your vehicle may have this feature. Use your fog lamps
for better vision in foggy or misty conditions. Your
ignition must be in RUN for your fog lamps to work.
The fog lamp button is
located on the instrument
panel to the right of
the exterior lamps knob.
Press the button to turn the fog lamps on. Press the
button again to turn them off. A light will glow near the
button while the fog lamps are on. Fog lamps will
turn off whenever your high-beam headlamps are on.
Some localities have laws that require the headlamps to
be on along with the fog lamps.

panel outlets.
)(Bi-Level):This mode directs about half of the air
to the instrument panel outlets; then directs most of
the remaining air to the oor outlets. A little air is
directed toward the windshield and the side window
outlets. Cooler air is directed to the upper vents
and warmer air to the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets with a little air directed to the windshield

When the temperature outside is 0°F (-18°C) or lower,
use the engine coolant heater, if the vehicle has one,
to provide warmer air, faster to your vehicle.#(Air Conditioning):Press this button to turn the
air-conditioning system on or off. When the button
is pressed, an indicator light will come on and the
system will begin to cool and dehumidify the air inside
of the vehicle. You may notice a slight change in engine
performance when the air conditioning compressor
shuts off and turns on again. This is normal.

mode can be used with vent and bi-level modes, but it
cannot be used with oor, defog or defrost modes.
Defog and defrost modes are described later in
this section.
If recirculation mode is selected with oor, defog, or
defrost modes, the indicator will ash three times and
then turn off indicating the selection is not available.
You may also notice that the air conditioning compressor
will run while in recirculation mode. This is normal
and will help to prevent fogging.
If the weather is cold and damp, the system may cause
the windows to fog while using recirculation mode.
If the windows do start to fog, select defog or defrost
mode and increase fan speed.
Recirculation mode, if selected, will be cleared when the

If your vehicle has heated mirrors, they will come on
when this button is pressed.
Notice:Do not use a razor blade or sharp object
to clear the inside rear window. Do not adhere
anything to the defogger grid lines in the rear glass.
These actions may damage the rear defogger.
Repairs would not be covered by your warranty.
Outlet Adjustment
Use the air outlets located in the center and on the side
of the instrument panel to direct the airow. Use the
thumbwheels near the air outlets to open or close off
the airow.
Operation Tips

Clear away any ice, snow, or leaves from air inlets
at the base of the windshield that could block the
ow of air into the vehicle.
Keep the path under the front seats clear of objects
to help circulate the air inside of the vehicle more
effectively.
Use of non-GM approved hood deectors can
adversely affect the performance of the system.
Check with your dealer/retailer before adding
equipment to the outside of your vehicle.
Rear Climate Control System
Your vehicle has one of the following rear climate
control systems. With either of these systems, the rear
climate controls will be disabled when the front
climate control system is in defrost. This occurs to
provide maximum airow to clear the windshield.

Speedometer and Odometer
The speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h).
The odometer shows how far your vehicle has been
driven, in either miles (used in the United States)
or kilometers (used in Canada).
The odometer mileage can be checked without the

the instrument panel cluster.
If your vehicle needs a new odometer installed,
the new one will be set to the correct mileage total
of the old odometer.
Trip Odometer
The trip odometer can tell you how far your vehicle has
been driven since you last set the trip odometer to zero.
The odometer works together with the Driver Information
Center (DIC). You can set a Trip A and Trip B odometer.
See “Trip Information” underDIC Operation and Displays
on page 3-50.
The odometer mileage can be checked without the
vehicle running. Press the trip stem on the instrument
panel cluster.
Tachometer
The tachometer
displays the engine
speed in revolutions
