Flow-Through Ventilatr'on System
I
KO502
Your vehicle's flow-through ventilation system supplies outside air to\
the inside
of your vehicle when it
is moving. With the side windows closed, air will flow
into the front air inlet grilles, through the vehicle, and out\
the rear air exhaust
valves. Outside air will also enter the vehicle when the heate\
r or the air
conditioning fan is running.
Ventilation Tips
e
e Keep the hood and front air inlet free of ice, snow, or any other
obstruction (such as leaves). The heater and defroster will w\
ork far better, reducing the chance of fogging the inside of your wind\
ows.
When you enter a vehicle in cold weather, turn the blower fan
to HI for
a few moments before driving off. This helps clear the intake ducts of
snow and moisture, and reduces the chance of fogging the inside of
your windows.
Keep the air path under the front seats clear of objects. This helps air
to circulate throughout your vehicle.

Air Vents
You will find air vents in the center and on the sides of your instrument
panel. You can move the vents to direct the flow of air, or close the vents
altogether. When
you close a vent, it will increase the flow of air coming out
of any vents that are open.
If your vehicle does not have air conditioning, there are air vents in each kick
panel below the instrument panel. Each vent has
a handle to open and close
it.

HeatingAir Conditioning System
K05ur
If your vehicle has air conditioning, your heatinglair conditioning \
system will
look like this.
Before using your vehicle’s air conditioning, open the window\
s to clear the
vehicle of hot air.
Fan Lever
The lever at the top of the system has four positions. To increase the air
flow, move the lever toward
H1. To decrease the air flow, move it toward LO.
Temperature Lever
The lever on the left of the system display lets you select the temperature of
the air coming into your vehicle. Move the lever up for warmer air. Move the
lever down for cooler air.
Function Lever
The lever on the right of the system can be moved to seven different heating
and air conditioning functions.
DEFROST This setting operates the defroster. Most of the air comes out
near the windshield, with some going to the floor vents and s\
ide window
defrost vents. Use this when you get fog or ice on the windshield.
HTR (Heater): Most of the air comes out near the floor. The rest comes out
from the defroster vents under the windshield and at your front
side windows.
This is best for cold weather.

Service & Appearance Care
To Check Brake Fluid:
You can check the brake fluid without taking off the cap. Just look at the
windows on the brake fluid reservoir. The fluid levels should be above
MIN. If
they aren’t, have your brake system checked to see if there is a leak.
After work is done on the brake hydraulic system, make sure t\
he levels are above
MIN and below the top of each window.
What To Add
When you do need brake fluid, use only DOT-3 brake fluid-such as Delco
Supreme
11 @ (GM Part No. 1052535). Use new brake fluid from a sealed
container only.
Replacing Brake System Parts
The braking system on a modern vehicle is complex. Its many parts have to
be of top quality and work well together if the vehicle is to have really good
braking. Vehicles we design and test have top-quality GM brake parts in
them, as your vehicle does when
it is new. When you replace parts of your
braking system-for example, when your brake linings wear down and you
have to have new ones put in-be sure you get new genuine GM
replacement parts.
If you don’t, your brakes may no longer work properly. For
example,
if someone puts in brake linings that are wrong for your vehicle, the
balance between your front and rear brakes can change, for the\
worse. The braking performance you’ve come
to expect can change in many other ways
if someone puts in the wrong replacement brake parts.
Fluid Leak Check
After the vehicle has been parked for a while, inspect the su\
rface under the
vehicle for water, oil, fuel or other fluids. Water dripping from the air
conditioning system after
it has been used is normal. If you notice fuel leaks
or fumes, the causes should be found and corrected at once.

o rep ace your wlndshleld wiper blade inserts, lift the wiper ar\
m away from
the windshield. Pinch the
two tabs on the wiper arm and slide the insert out
of the bl'ade. Slide the new one in place. Make sure the tabs are locked into
position.
Air Conditioning
Every now and then have your dealership check your alr conditi\
oning system
to be sure it has not lost any cooling ability. If you think the system is not
working prope'rly, have your dealership check
it out as soon as possible.
The air conditioning will not work when the temperature is below
40°F (4°C).
Lubrication
Accelerator Control System
Refer to the Maintenance Schedule to determine how often the accelerator
linkage pivot points must be lubricated and what type
of lubricant to use.
Accelerator cables and cruise control cables should not be lubr\
icated. Any
cables that are worn or are hard
to pull should be replaced.
When cleaning the engine compartment with water or steam, avoid\
directing
the flow onto the throffle linkage in a manner that would cause moisture
to
enter the cables.
