Your air cleaner is located between the battery and
coolant recovery tank. The air cleaner assembly
has an
indicator that lets
you know when the air
filter is dirty and needs
to be serviced.
The indicator is located in the air intake tube between
the air cleaner and the engine. See “Owner Checks and
Services” in the Index to determine when to check
the indicator.
If the area inside the clear section
of the indicator is
green, no air filter service is required. When the area
inside
the indicator is orange and CHANGE AIR
FILTER appears, the filter should be replaced.

Downloaded from www.Manualslib.com manuals search engine To remove the air filter, unhook the retainer clips and
remove the cover. Lift the filter and the connected duct
out of the air cleaner housing. Hold the duct and remove
the filter by both pulling and twisting the filter away
from the duct. Care should be taken to dislodge as little
dirt as possible.
Clean the filter sealing surface of the duct and the
filter housing. Install
the new filter by pushing it all the way to the stop
on the duct.
Install the duct and the filter into the air cleaner housing.
Make sure that the duct fits properly into the housing.
Install the cover and fasten the two retaining clips.
After the air filter is properly serviced, the indicator
should be reset. Push the button on top
of the indicator
to reset
it to the green (clean) filter zone.

Downloaded from www.Manualslib.com manuals search engine Refer to the Maintenance Schedule to determine when to
replace the
air filter. See “Owner Checks and Services”
in the Index.
A CAUTION:
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
backfhes.
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.
Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more
of these conditions:
0 In heavy city traffic where the outside temperature
regularly reaches
90°F (32 “C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
See “Scheduled Maintenance Services” in the Index.
How to Check
Because this operation can be a little difficult, you
may choose to have this done at your
GM dealership
Service Department.

Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages are
working properly. Look for any other loose or damaged

repaired. Have any torn or frayed safety belts replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag system
does not need regular maintenance.)

for more information. Inspect your air cleaner filter
restriction indicator more often if the vehicle is used in
dusty areas or under
off road conditions.

Check the transmission fluid level; add if needed. See
“Automatic Transmission” in the Index. A fluid loss
may indicate a problem. Check the system and repair
if needed.
At Least Once a Year
