2007 CHEVROLET TRAIL BLAZER display

The passenger’s side temperature setting also
resets and relinks to the driver’s side temperature
setting if the vehicle has been off for more
than three hours.
Outside Air Temperature Display
A new outside temperature reading will be
displayed if the vehicle has been off for more
than three hours. If the vehicle has been off for
less than three hours, the old temperature
reading may be displayed because underhood
heat is affecting the true outside temperature.
Underhood heat can also affect the outside
temperature while the engine is running.
It may also take several minutes of driving
before the display updates to the actual
outside temperature.
Automatic Operation
AUTO (Automatic):When automatic operation
is active, the system will control the inside
temperature, the air delivery mode, and the
fan speed.Use the steps below to place the entire system
in automatic mode:
1. Press the AUTO button.
When AUTO is selected, the air conditioning
operation and air outlet mode will be
automatically controlled. The air conditioning
compressor will run continuously when the
outside temperature is over approximately
40°F (4°C). The air inlet will normally be set to
outside air. If it’s hot outside, the air inlet will
automatically switch to recirculate inside air to
help quickly cool down your vehicle.
2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a
72°F (22°C) temperature setting and allow
about 20 minutes for the system to adjust.
Turn the driver’s or passenger’s side
temperature knob to adjust the temperature
setting as necessary. If you choose the
temperature setting of 60°F (15°C), the system
will remain at the maximum cooling setting.
If you choose the temperature setting of
90°F (32°C), the system will remain at the
maximum heat setting. Choosing either
maximum setting may not cause the vehicle
to heat or cool any faster.

Manual Operation
To change the current setting, select one of the
following:
w9x(Fan):This button allows you to manually
adjust the fan speed. Press the up arrow to
increase fan speed and the down arrow to
decrease fan speed. The display will change to
show you the selected fan speed and the driver’s
side temperature setting for ve seconds.
C(Mode):Press this button to manually change
the direction of the airow in your vehicle. Keep
pressing the button until the desired mode appears
on the display. The display will change to show
you the selected air delivery mode and the driver’s
temperature setting for ve seconds.
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs approximately
half of the air to the instrument panel outlets,
then directs 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 outlets and warmer air to the oor
outlets.
6(Floor):This mode directs most of the air
to the oor outlets. Some air also comes out
of the defroster and side window outlets.
The recirculation button cannot be selected in
oor mode.
@(Recirculation):Press this button to turn
recirculation mode on or off. When this button
is pressed, an indicator light in the button will
also come on to let you know that it is activated.
Recirculation mode is used to recirculate the
air inside of your vehicle. Use this mode to help
prevent outside odors and/or dust from entering
your vehicle or to help cool the air inside of
your vehicle more quickly. Recirculation 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 engine is turned off.
#A/C (Air Conditioning):Press this button
to manually turn the air conditioning system on
or off. When the system is on, the system
will automatically begin to cool and dehumidify
the air inside of your vehicle. The air conditioning
symbol will appear on the display when the
air conditioning is on and will turn off when the
air conditioning is off.If you turn the air conditioning off while in front
defrost or defog mode, the air conditioning symbol
will turn off, however, the A/C compressor will
remain on to help de-humidify the air inside
the vehicle. If one of the other modes is selected
the compressor will then turn the A/C off until
it is selected again or the AUTO button is pressed.
To avoid fogging the inside glass on rainy and
humid days at a temperature above freezing,
press the air conditioning button to run the A/C
compressor. Also it is best to avoid the use of the
recirculation mode except when maximum air
conditioning performance is needed or for short
times to avoid exterior odors.
You may notice a slight change in engine
performance when the air-conditioning compressor
shuts off and turns on again. This is normal.

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 vehicle running. Press the trip stem located
on 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 221.
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
per minute (rpm).
Safety Belt Reminder Light
When the key is turned to RUN or START,
a chime will sound for several seconds to remind
you buckle your safety belt. The driver safety
belt light will also come on and stay on for several
seconds, then it will ash for several more.
You should buckle your seat belt.
This chime and
light will be repeated
if the driver remains
unbuckled and the
vehicle is in motion.
If the driver’s belt is buckled, neither the chime
nor the light will come on.

Voltmeter Gage
When your engine is
not running, but the
ignition is in RUN,
this gage displays
the battery voltage
in DC volts.
When the engine is running, the gage shows the
condition of the charging system. The gage may
transition from a higher to lower or a lower to higher
reading. This is normal. Readings between the
low and high warning zones indicate the normal
operating range. The voltmeter gage may also read
lower when in fuel economy mode. This is normal.Readings in the low warning zone may occur
when a large number of electrical accessories
are operating in the vehicle and the engine is
left idling for an extended period. This condition
is normal since the charging system is not able
to provide full power at engine idle. As engine
speeds are increased, this condition should correct
itself as higher engine speeds allow the charging
system to create maximum power.
You can only drive for a short time with the
reading in either warning zone. If you must drive,
turn off all unnecessary accessories.
Readings in either warning zone indicate a
possible problem in the electrical system.
Have the vehicle serviced as soon as possible.
