Flow-Through Ventilation System
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 valve. Outside air will also enter the vehicle when the heater
or
the air conditioning fan is running.
Ventilation Tips
Keep the hood and front air inlet free of ice, snow, or any other
obstruction (such
as leaves). The heater and defroster will work far
better, reducing the chance of fogging the inside
of your windows.
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.

Downloaded from www.Manualslib.com manuals search engine 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.
Heater Controls
If your vehicle does
not have air
conditioning, your
heater controls will
look like this.
Fan Lever:
The lever at the top of the system has four positions. To increase the air
flow, move the lever toward HI. To decrease the air flow, move it toward
OFF.

DEFROST: This setting operates the defroster. Most of the air comes out
near the windshield,
with some going to the floor vents and side 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 the front side windows.
This
is best for cold weather.
VENT: The air comes out at the vents on your instrument panel and at your
front side windows.

Downloaded from www.Manualslib.com manuals search engine 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 surface 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.
Battery
Every new vehicle has a Delco Freedom@ battery. You never have to add
water
to one of these. When it’s time for a new battery, we recommend a
Delco Freedom@ battery. Get one that has the catalog number shown on the
original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days or more, take off the
black, negative
(-) cable from the battery. This will help keep your battery
from running down.
Contact your dealer to learn how to prepare your vehicle for longer storage
periods.

To replace your
windshield wiper
blade inserts, lift the
wiper
arm away from
the windshield. Pinch
the two tabs on the
wiper arm and slide
the insert out of the
blade. 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 air conditioning
system to be sure it has not lost any cooling ability.
If you think the system
is not working properly, 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 lubricated. 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 throttle linkage in a manner that would cause moisture to
enter the cables.
Hood Latches and Hood Hinge
Refer to the Maintenance Schedule to determine how to lubricate the hood
latch and hood hinge assembly.
