Operation Tips

Clear away any ice, snow or leaves from the
air inlets at the base of the windshield that
may block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the
system.
Keep the path under the front seats clear of
objects to help circulate the air inside of
your vehicle more effectively.
Passenger Compartment Air Filter
The passenger compartment air lter traps most of
the pollen from the air entering your vehicle.
Like your vehicle’s engine air cleaner/lter, it needs
to be changed periodically. SeeScheduled
Maintenance on page 462.
Using the climate control system without the
passenger air lter installed may allow water or
other debris to enter the system. This could cause
a water leak or noises. Make sure to install a
new air lter after removing the old one.The passenger compartment air lter is located
underneath the hood below the windshield
wiper arm on the passenger’s side of the vehicle.
SeeEngine Compartment Overview on page 342
for more information on location.
Use the procedure listed below to replace the
passenger compartment air lter:
1. Turn the ignition to ON with the engine off.
2. Turn on the windshield wipers and turn them
off again when the wipers are straight on the
windshield.
This allows you access to the leaf screen.
The passenger compartment air lter is
located under the leaf screen.

What to Do with Used Oil
Used engine oil contains certain elements that may
be unhealthy for your skin and could even cause
cancer. Do not let used oil stay on your skin for very
long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly
dispose of clothing or rags containing used engine
oil. See the manufacturer’s warnings about the use
and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from
the lter before disposal. Never dispose of oil by
putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used
oil. If you have a problem properly disposing of your
used oil, ask your dealer, a service station or a local
recycling center for help.
Engine Air Cleaner/Filter
The engine air cleaner/lter is in the engine
compartment on the driver’s side of the vehicle,
near the front. SeeEngine Compartment Overview
on page 342for more information on location.

When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/lter at the MaintenanceII
intervals and replace it at the rst oil change
after each 50,000 mile (83 000 km) interval. See
Scheduled Maintenance on page 462for more
information. If you are driving in dusty/dirty
conditions, inspect the lter at each engine oil
change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/lter, remove the lter
from the vehicle and lightly shake the lter to
release loose dust and dirt. If the lter remains
caked with dirt, a new lter is required.
To inspect or replace the engine air cleaner/lter,
do the following:
1. Remove the two screws located on the sides
of the cover.
2. Lift the cover off.3. Inspect or replace the engine air cleaner/lter.
SeeNormal Maintenance Replacement Parts
on page 475for the correct part number
for the lter.
4. Reinstall the cover by reversing Steps 1 and 2.
{CAUTION:
Operating the engine with the air
cleaner/lter off can cause you or others
to be burned. The air cleaner not only
cleans the air; it helps to stop ames if
the engine backres. If it is not there and
the engine backres, you could be
burned. Do not drive with it off, and be
careful working on the engine with the air
cleaner/lter off.
Notice:If the air cleaner/lter is off, a backre
