Checking or Replacing the Air Cleaner
1. Unlatch the two hooks on top of the air
cleaner housing.
2. Turn back the air inlet panel and rest it on top of the
housing. The air intake tube is designed to flex back;
you do not need to disconnect it.
3. After replacing the air cleaner filter, seat the tabs on
the bottom of the panel into the slots at the bottom.
4. Latch the hooks to secure the panel in place. If the
panel moves easily, check that the tabs
are seated
correctly in
the slots.
Operating the engine with the
air cleaner off can
cause you or others to be burned. The air cleaner
not only cleans the air, it stops flame
if the engine
backfires.
If it isn’t there, and the engine
backfires, you could be burned. Don’t drive with
it
off, and be careful working on the engine with
the air cleaner
off.
NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always
have the air cleaner in place when you’re driving.
Passenger Compartment Air
Filter Replacement
Passenger compartment air, both outside and
recirculated air, is routed through
a passenger
compartment filter, which is part of
a two-piece filter
system. The filter removes certain contaminants from
the air, including pollen and dust particles. Reductions
in airflow, which may occur more quickly in dusty
areas, indicate that the filter needs
to be replaced early.
For how often to change the air filter, see “Maintenance
Schedule” in the Index.
The access panel for the air filter is in the back
of the
glove box.

this position.
3. Pull the windshield wiper arrn away from the
windshield or backglass. 4. While holding the wiper arm away from the glass,
push the release clip from under the blade
connecting point and pull the blade assembly down

~
~ 1 Tire Chains
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire or tire
chain clearance to the body and chassis.
See “Changing a Flat Tire” in the Index for
more information.
Putting
a used wheel on your vehicle is
dangerous. You can’t know how it’s been used or
how
far it’s been driven. It could fail suddenly
and cause an accident.
If you have to replace a
wheel, use a new GM original equipment wheel.
NOTICE:
Use tire chains only where legal and only when
you must. Use only
SAE Class “S” type chains
that are the proper size for your tires. Install
them on the front tires and tighten them
as
tightly as possible with the ends securely
fastened. Drive slowly and follow the chain
manufacturer’s instructions.
If you can hear the
chains contacting your vehicle, stop and retighten
them.
If the contact continues, slow down until it
stops. Driving
too fast or spinning the wheels
with chains on will damage your vehicle.
