2004 CHEVROLET BLAZER air condition

{CAUTION:
If something is between an occupant and an
air bag, the bag might not inate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inating air bag must be kept clear. Don’t put
anything between an occupant and an air bag,
and don’t attach or put anything on the
steering wheel hub or on or near any other air
bag covering.
When Should an Air Bag Inate?
An air bag is designed to inate in a moderate to severe
frontal, or near-frontal crash. The air bag will inate only if
the impact speed is above the system’s designed
'threshold level'. If your vehicle goes straight into a wall
that doesn’t move or deform, the threshold level is about
9 to 16 mph (14 to 26 km/h). The threshold level can vary,
however, with specic vehicle design, so that it can be
somewhat above or below this range. If your vehicle
strikes something that will move or deform, such as a
parked car, the threshold level will be higher. The air bag
is not designed to inate in rollovers, rear impacts, or in
many side impacts because ination would not help the
occupant.
In any particular crash, no one can say whether an air
bag should have inated simply because of the damage
to a vehicle or because of what the repair costs were.
Ination is determined by the angle of the impact
and how quickly the vehicle slows down in frontal or
near-frontal impacts.
The air bag system is designed to work properly under
a wide range of conditions, including off-road usage.
Observe safe driving speeds, especially on rough
terrain. As always, wear your safety belt. SeeOff-Road
Driving with Your Four-Wheel-Drive Vehicle on
page 4-15for more tips on off-road driving.

This vehicle has one
double-sided key for the
ignition, tailgate and
door locks. It will t with
either side up.
When a new vehicle is delivered, the dealer provides
the owner with a pair of identical keys and a key
code number.
The key code number tells your dealer or a qualied
locksmith how to make extra keys. Keep this number in
a safe place. If you lose your keys, you’ll be able to
have new ones made easily using this number.
Your selling dealer should also have this number.
Notice:If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.
If you ever do get locked out of your vehicle, contact
Roadside Assistance for help. SeeRoadside Assistance

Notice:Shifting out of PARK (P) or NEUTRAL (N)
with the engine running at high speed may damage
the transmission. The repairs would not be covered
by your warranty. Be sure the engine is not running
at high speed when shifting your vehicle.
DRIVE (D):This position is for normal driving. If you
need more power for passing, and you’re:
Going less than about 35 mph (55 km/h), push your
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You’ll shift down to the next gear and have more power.
DRIVE (D) should not be used when towing a trailer,
carrying a heavy load, driving on steep hills or for
off-road driving. Select THIRD (3) when operating the
vehicle under any of these conditions.
THIRD (3):This position is also used for normal driving.
It offers more power and lower fuel economy than
DRIVE (D). You should use THIRD (3) when towing a
trailer, carrying a heavy load, driving on steep hills
or winding roads or for off-road driving.SECOND (2):This position gives you more power but
lower fuel economy than THIRD (3). You can use
SECOND (2) on hills. It can help control your speed as
you go down steep mountain roads, but then you
would also want to use your brakes off and on.
You can also use SECOND (2) for starting your vehicle
from a stop on slippery road surfaces.
FIRST (1):This position gives you even more power
but lower fuel economy than SECOND (2). You can use
it on very steep hills, or in deep snow or mud. If the
shift lever is put in FIRST (1) while the vehicle is moving
forward, the transmission won’t shift into rst gear
until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle
in one place on a hill using only the accelerator
pedal may damage the transmission. If you are
stuck, do not spin the tires. When stopping on
a hill, use the brakes to hold the vehicle in place.

Temperature and Compass Display
The outside air temperature and the compass are
displayed at the front of the overhead console.
The buttons are located to the left of the display.
ON/OFF:Press this button to turn the display on or off.
US/MET:Press this button for the temperature to be
displayed in either degrees Farenheit (English) or
Celsius (metric).Before you turn on the ignition and move the vehicle,
the temperature indicated will be the last outside
temperature recorded with the ignition on.
If the outside temperature is 37°F (3°C) or lower when
you turn on the ignition, the word ICE will appear
on the display. This is a warning to the driver that road
conditions may be icy, and that appropriate precautions
should be taken.
The compass is self-calibrating, so it does not need to
be manually set. However, when your vehicle is new,
the compass may function erratically. If it does,
CAL (Calibration) will appear on the display. To correct
the calibration, drive in a complete 360° circle three
times and the compass will function normally.
Variance is the different between magnetic north and
geographic north. In some areas, the difference between
the two can be great enough to cause false compass
readings. If this happens, follow these instructions to set
the variance for your particular location:

Driver Information Center (DIC)
If your vehicle is equipped with a Driver Information
Center (DIC), this system displays the outside air
temperature, compass direction and trip information in
the overhead console.
US/MET (United States/Metric):The US/MET
(United States/metric) button allows you to switch the
display between the English and metric system.
MODE:The MODE button can be used to toggle
between three modes of operation: OFF, COMP/TEMP
and TRIP.
COMP/TEMP (Compass/Temperature):The display
provides the outside temperature and one of eight
compass readings to indicate the direction the vehicle
is facing.
Before you turn on the ignition and move the vehicle,
the temperature indicated will be the last outside
temperature recorded with the ignition on. If the outside
temperature is 37°F (3°C) or lower, the display will
toggle between the ICE and the current temperature
every eight seconds. This is a warning to the drive that
road conditions may be icy, and that appropriate
precautions should be taken.The compass is self-calibrating, so it does not need to
be manually set. However, if C (Calibration) is displayed,
the compass will need to be calibrated. You may also
place the compass in a noncalibrated mode by pressing
the holding the MODE and US/MET buttons at the
same time while in the COMP/TEMP mode. After about
10 seconds, the compass will display C and you can
release the buttons. Drive the vehicle in a complete
360° circle three times at a speed of less than 5 mph
(8 km/h), and the compass will function normally.
Once the calibration is complete, the display will return
to a compass reading.
Variance is the different between magnetic north and
geographic north. In some areas, the difference between
the two can be great enough to cause false compass
readings. If this happens, follow these instructions to set
the variance for your particular location:

Directing the Airow
Mode Knob:Turn the right knob clockwise or
counterclockwise to direct the airow inside of your
vehicle.
H(Vent):This mode directs air to the instrument
panel outlets, with a little air directed toward the oor
outlets.
)(Bi-Level):This mode directs half of the air to the
instrument panel outlets, then directs most of the
remaining air to the oor outlets. A little air is also
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 with a little air directed to the windshield and
the side window outlets.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
Turn the mode knob to OFF to turn off the fan.
The mode knob can also be used to select defog or
defrost mode. For more information, see “Defogging and
Defrosting” later in this section.
Heating
Turn the center knob clockwise or counterclockwise to
raise or lower the temperature on the inside of your
vehicle.
When it’s cold outside 0°F (−18°C) or lower, use the
engine coolant heater, if equipped, to provide warmer air
faster to your vehicle. An engine coolant heater warms
the coolant that the engine uses to provide heat to
warm the inside of your vehicle. For more information,
seeEngine Coolant Heater on page 2-22.
Cooling
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
A/C (Air Conditioning):Turn the knob to the A/C
position to turn the air-conditioning system on or
off. When the system is on, this setting cools and
dehumidies the air entering your vehicle and directs it
through the oor outlets as well as the instrument
panel outlets.
3-18

MAX A/C (Maximum Air Conditioning):This mode
recirculates much of the air inside your vehicle so
it cools quickly. It directs most of the air through the
instrument panel vents and a small amount through the
oor vents.
You may notice a slight change in engine performance
when the air-conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
For quick cool down on hot days, do the following:
1. Select A/C.
2. Select the coolest temperature.
3. Select the highest fan speed.
On cool, but sunny days, the sun may warm the upper
part of your body, but the lower part may not be
warm enough. To remedy this, do the following:
1. Select the bi-level mode.
2. Select the temperature.
3. Select the fan speed.
The air-conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. There are two modes to clear fog or frost
from your windshield and side windows. Use the
defog mode to clear the windows of fog or moisture and
warm the passengers. use the defrost mode to
remove fog or frost from the windshield more quickly.
For best results, clear all snow and ice from the
windshield before defrosting.
-(Defog):Use this mode to direct half the air to the
windshield and half to the oor outlet. Close the
center outlets to help defrost the side windows more
quickly. In this mode, the system will automatically force
outside air into your vehicle and it will also run the
air-conditioning compressor, unless it falls below the
temperature at which air conditioning is effective.
1(Defrost):This mode directs most of the air to the
windshield and the side window vents, with only a
little air directed to the oor vents. When you select this
mode, the system runs the air-conditioning compressor
unless the outside temperature is at or below freezing.
Do not drive the vehicle until all the windows are clear.
3-19

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
defogger on or off. An indicator light in the button
will come on to let your know that the rear window
defogger is activated.
If your vehicle has heated outside rearview mirrors,
when the rear defogger button is pressed the mirrors will
warm to help clear any fog or frost from the surface of
the mirrors.
Notice:Using a razor blade or sharp object to clear
the inside rear window may damage the rear
window defogger. Repairs would not be covered by
your warranty. Do not clear the inside of the rear
window with sharp objects.
Outlet Adjustment
The ow through outlets on your vehicle allow outside
air to enter your vehicle while it is moving. Outside
air will also enter your vehicle while the air-conditioning
compressor is running.
Use the thumbwheels located in the center and on the
sides, to change the direction of the air owing
through the outlets.
