air condition CHEVROLET BLAZER 1998 2.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine If something is between an occupant and an air
bag, the bag might not inflate properly or it
might force the object into that person. The path
of an inflating 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 inflate?
An air bag is designed to inflate in a moderate to severe
frontal or near-frontal crash. The air bag will inflate
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
14 to 18 mph (23 to 29 kdh). The threshold level
can vary, however, with specific 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 inflate in rollovers, side
impacts or rear impacts, because inflation would
not
help the occupant.
In any particular crash, no
one can say whether an air
bag
should have inflated simply because of the damage
to a vehicle or because
of what the repair costs were.
Inflation 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. See “Off-Road
Driving’’
in the Index for more tips on off-road driving.
What makes an air bag inflate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is
in a crash. The sensing
system triggers a release
of gas from the inflator, which
inflates the air bag. The inflator, air bag and related
hardware are all part
of the air bag modules inside the
steering wheel and in the instrument panel in front
of the
right front passenger.

Downloaded from www.Manualslib.com manuals search engine Temperature and Compass Display
The outside air temperature and the compass are
displayed at the front of the overhead console. The
control switches are located to the left of the display.
Turn the display on or
off by pressing the ON/OFF
switch. Display the temperature in either degrees
Fahrenheit (English) or Celsius (metric) by pressing the
USMET switch. 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 OF (3 "C) or lower when
you
turn on the ignition, 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
problem, drive in a complete
360" circle three times,
and the compass will function normally.
Variance is the difference 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:

Downloaded from www.Manualslib.com manuals search engine Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag’s electrical system for malfunctions.
The light tells
you if there is an electrical problem. The
system check includes the air bag sensors, the air bag
module, the wiring and the diagnostic module. For more information on the air bag system, see “Air Bag” in
the Index.
This light will come
on
when you start your engine,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
Charging System Indicator Light
If the air bag readiness light stays on after you start the
engine or comes on when
you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
The air bag readiness light should flash for a few
seconds when
you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you if there is a problem. The
charging system light
will
come on briefly when
you turn on the ignition,
but the engine is not
running, as
a check to
show
you it is working.
It should go out once the engine is running.
If it stays
on, or comes on while
you are driving, you may have a
problem with the charging system. It could indicate that
you have problems with a generator drive belt, or
another electrical problem. Have it checked right away.
Driving while this light is
on could drain your battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and air conditioner.

Your vehicle is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission
control systems.
This system is called OBD I1 (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The
SERVICE ENGINE SOON light
comes on
to indicate that there is a problem and service
is required. Malfunctions often will be indicated by
the system before any problem
is apparent. This may
prevent more serious damage to your vehicle. This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is
on and the engine is not
running. If the light doesn’t come on, have it repaired.
This light will also come
on during a malfunction in one
of two ways:

Downloaded from www.Manualslib.com manuals search engine Temperature Knob Mode Knob - Automatic Operation
The middle knob on the control panel lets you select the
desired air temperature in your vehicle. This knob will
allow
you to adjust the interior air temperature
independently
of the function knob setting. Move the
knob to the right toward
82 for warmer air. Move the
knob to the left toward 66 for cooler air.
Full Hot: If you turn the temperature knob past 82°F
(28”C), the system will go into the
“full hot” mode. The
system will remain at that maximum heating setting and
the fan will blow at the speed the fan knob is set to. If
the fan is in AUTO, it will run at
full speed.
Full Cold: If you turn the temperature knob past 66°F
(1 9”C), the system will go into the “full cold” mode.
The system will remain at that maximum cooling setting
and the fan will blow at the speed the fan knob is set to. \
If the fan is in AUTO, it will run at
full speed.
Choosing either maximum setting will
not cause the
system to heat or cool any faster. The right knob
on the control panel allows you to
choose the direction of air delivery. When the system is
set for automatic operation, sensors will control the air
delivery mode. Air will come primarily from the floor or
instrument panel outlets, with some air directed to the
windshield
to prevent fogging.
When the system is
in AUTO mode, the air conditioning
light
will turn on, and the recirculation and outside air
lights turn off. With the system in full auto control (both
the fan and mode knobs in AUTO), you still have the ability to override any function. However, continually
overriding the outside air or the A/C compressor will
limit the ability of the system
to cool the
vehicle quickly.
If
you push a button for a function which is not
available,
the light next to that button will flash three
times
to alert you that it’s not available.
To find your comfort zone, start with the
74°F (23°C)
setting and allow about 20 minutes for the system to
adjust the temperature
if necessary.

Downloaded from www.Manualslib.com manuals search engine With the automatic setting, the air conditioning
compressor automatically cycles when needed to cool
the air. In cold weather, when the system senses the need
for heat, the airflow will be directed out the floor
outlets.
As the interior temperature approaches a desired
setting, the blower speed will decrease. To maintain
interior comfort, the airflow will adjust between the
instrument panel air outlets and floor outlets. On bright
sunny days in cool weather, the airflow may come out of
the air conditioning and floor outlets (bi-level mode) to
maintain comfort and prevent stuffiness.
To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the outside air
temperature, engine coolant temperature or the time
since the engine was last started. As the coolant warms
up, the blower fan speed will gradually increase and air
will flow from the heater outlets, with some airflow to
the windshield to prevent fogging under most
normal conditions.
If your vehicle
is sitting out on a warm day and you
have the fan set
on AUTO, the air will first flow out of
the floor air outlets for a few seconds. That is normal.
This
is to expel hot air from the air outlets. As the air is
cooled, the airflow will move through the air
conditioning outlets. Be careful
not to put anything over the solar sensor
located around the center of the instrument panel.
This sensor is used by the automatic system to
regulate temperature.
Mode Knob - Manual Operation
The right knob on the control panel allows you to
choose the direction of air delivery.
You can choose to set the climate control system
operations yourself, or let the system work for
you
by placing the system in AUTO mode. See “Mode
Knob
- Automatic Operation” earlier in this section.

a OUTSIDE AIR: Press this button to force the
system to use outside air. Press it again to close off the
outside air.
Pressing the OUTSIDE AIR button
will cancel the
RECIRCULATION button.
RECIRCULATION: Press this button to limit
the amount of fresh air entering your vehicle. This is
helpful when you are trying to limit odors entering your
vehicle. In the AUTO mode, the system
will use
recirculation as necessary
to cool the air. Pressing the
recirculation button
will change the operation to a
manual mode and the air will recirculate non-stop. Press
this button again to turn off the recirculation feature. RECIRCULATION may be selected
with the fan control
in OFF to limit odors, outside
air and dust from entering
your vehicle.
Pressing the RECIRCULATION button
will cancel the
OUTSIDE AIR button.
A/C: Press this button to turn the air conditioning
on and
off. The system will cool and dehumidify the air
inside the vehicle when the A/C light
is on.
Air conditioning
will be automatically disabled when
the outside temperature drops below a level which air
conditioning is ineffective.
Remember that
in order for the automatic system to perform
well,
it needs A/C to provide cooling performance.

Downloaded from www.Manualslib.com manuals search engine Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle
to cool down. Then keep your windows closed
for the air conditioner to work its best.
For quick cool-down on very hot days, use MAX A/C
with the temperature knob turned to the left. This setting
should be used to keep odors and/or dust from entering
the vehicle. For normal cooling
on hot days, use A/C
with the temperature knob turned to the left.
On vehicles equipped with the Electronic Climate
Control system, this same performance can be achieved
as long as the A/C is enabled and the outside air button
is not active.
Heating
On cool but sunny days, use BI-LEVEL A/C to deliver
warm air to the
floor and cooler air to the instrument
panel outlets.
When the air conditioner is on, you may sometimes
notice slight changes in your vehicle’s engine speed and
power. This is normal because the system is designed
to cycle the compressor on and off to keep the
desired temperature.
The heater works best if you keep your windows closed
while using it. On cold days,
use HEATER with the
temperature knob turned
to the right. BLEND is useful
in cool weather when
you have fog or ice on the
windshield or side windows.
If you use the optional engine coolant heater before starting your engine, your heating system will produce
warmer air faster to heat the passenger compartment in
cold weather. See “Engine Coolant Heater” in the Index.
Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use
VENT to direct outside air
through your vehicle. Airflow is through the instrument
panel outlets.
Your vehicle’s ventilation system supplies outside air to
the inside
of your vehicle when it is moving. When the
vehicle is
not moving, you can get outside air to flow
through by selecting any mode and any fan speed.
