iescribed later in this section.
3FF: Press to turn the blower off. Air
vi11 still come from the outlets at the
loor. Press any function button to turn
.he system on.
remperature Control Lever: This lever
:hanges the temperature of the air
:oming through the system. The higher
.he lever setting, the warmer the air.
8: Selects the force of air you want.
Press
LO to lower the fan speed, HI to
raise it.
Air Conditioning
On very 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, which should help
fuel economy.
There are three
air conditioning settings:
MAX: Provides maximum cooling or
quick cool-down on very hot days. This
setting also helps prevent outside odors
from entering your vehicle.
This setting recirculates much of the air
inside your vehicle, and it should not be
used for long periods because the air
may become too cold and dry. This
setting is not recommended if an
occupant is smoking.
NORM: Use for normal cooling on hot
days. This setting brings in outside air, cools
it and directs it through the
instrument panel outlets.
BI-LEV (Bi-Level): Use on cool, but
sunny days. This setting brings in
outside air, but directs it in two ways.
The cool air is directed to the upper
portion of your body through the
instrument panel outlets, but most
warmed air is directed through the
heater ducts and a little to the defrost
and side window vents. At times this
temperature difference may be more
apparent than others.
Heating and Ventilation
When you don’t need to cool the
outside air, use these next settings. You
can leave the air as it is or heat it.
The air conditioner compressor doesn’t
run in these settings. This reduces the
engine load, resulting in improved fuel
economy (gas mileage).
VENT: For mild outside temperatures,
when little heating or cooling is needed,
push
VENT. Air flow is through the
instrument panel outlets. Slide the
temperature control lever to a
comfortable level.

If the Fahrenheit (F") or Celsius (C")
symbol begins to flash, or flashes when
you turn on the ignition, it indicates an
electrical problem with your air

continue for about two minutes. It
means you should have your system
serviced.

When the following buttons are pressed,
an indicator light will glow above the
button.
BI-LEV (Bi-Level): Use on cool, but
sunny days. This setting brings in the
outside air, but directs it in
two ways.
The cool air is directed to the upper
portion of your body through the instrument

apparent than others.
You may notice a delay of three or four
minutes before the blower comes on.

The proper fluids and lubricants to use
are listed in Section D. Make sure
whoever services your vehicle
uses
these. All parts should be-replaced and
all necessary repairs done before you or
anyone else drives the vehicle.
ITEM SERVICE
NO.
1. Engine Oil and Filter Change* -
Always use SH or SG Energy
Conserving I1 oils of proper viscosity.
The “SH” or “SG” designation may
be shown alone or in combination
with others, such as “SH/CD,” “SH,
SG, CD,”“SG/CD,” etc. To
determine the preferred viscosity for
your vehicle’s engine (e.g., SAE 5W-
30 or SAE 10W-30), see
Engine Oil
in the Index.
2. Chassis Lubrication - Lubricate
suspension and steering linkage.
Lubricate the transaxle shift linkage,
and parking brake cable guides,
underbody contact points and
linkage.
3. Tire and Wheel Rotation and
Inspection
- For proper wear and
maximum tire life, rotate your tires
following the instructions in this
manual. See
Tires, Inspection 6
Rotation in the hdex. Check the
tires for uneven wear or damage.
If
you see irregular or premature wear,
check the wheel alignment. Check for
damaged wheels also.
Inspection *‘ - Inspect the belt for
cracks, fraying, wear and proper
tension. Replace as needed.

conforming
to GM Specification
1825M. Keep coolant at the proper
mixture as specified. See
Coolant in

Index. This provides proper
freeze and boil protection, corrosion
inhibitor level and maintains proper
engine operating temperature.
Inspect hoses and replace
if they are
cracked, swollen or deteriorated.
Clean the outside of the radiator and
air conditioning condenser. Wash the
pressure cap and neck.
To help ensure proper operation, we
recommend a pressure test of both
the cooling system and the pressure
cap.
