.Keep the path under the front
seats clear of objects to help
circulate the air inside of the
vehicle more effectively.
. Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
Check with your dealer before
adding equipment to the outside
of the vehicle.Maintenance
Passenger Compartment
Air Filter
The passenger compartment air
filter reduces dust, pollen, and other
airborne irritants from outside air
that is pulled into the vehicle. The
filter will need to be replaced
periodically. See Maintenance
Schedule 0364.
Using the climate control system
without an air filter installed is not
recommended. Water or other
debris could enter the system and
result in leaks or noises. Always
install a new filter when removing
the old filter.
For more information on filter
replacement, see your dealer.

If the vehicle has a diesel engine,
see the Duramax diesel
supplement.Engine Oil
For diesel engine vehicles, see
“Engine Oil” in the Duramax diesel
supplement.
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
. Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
. Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0286.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
Check the engine oil level regularly,
every 650 km (400 mi), especially
prior to a long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment Overview
0281 for the location.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
If a low oil Driver Information Center
(DIC) message displays, check the
oil level.
Follow these guidelines:
. To get an accurate reading, park
the vehicle on level ground.
Check the engine oil level after
the engine has been off for at
least two hours. Checking the
engine oil level on steep grades
or too soon after engine shutoff
can result in incorrect readings.
Accuracy improves when

Automatic Transmission
Fluid
How to Check Automatic
Transmission Fluid
It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to your
dealer and have it repaired as soon
as possible.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, this should be
done at your dealer. Contact your
dealer for additional information or
the procedure can be found in the
service manual. To purchase a
service manual, seeService
Publications Ordering Information
0 390.
Change the fluid and filter at the
intervals listed in Maintenance
Schedule 0364, and be sure to use
the fluid listed in Recommended
Fluids and Lubricants 0373.

How to Check Manual
Transmission Fluid
It is not necessary to check the
manual transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to your
dealer and have it repaired as soon
as possible. See Recommended
Fluids and Lubricants 0373 for the
proper fluid to use.
Hydraulic Clutch
For vehicles with a manual
transmission, it is not necessary to
regularly check brake/clutch fluid
unless there is a leak suspected.
Adding fluid will not correct a leak.
A fluid loss in this system could
indicate a problem. Have the
system inspected and repaired.
When to Check and What
to Use
The brake/hydraulic clutch fluid
reservoir cap has this symbol on it.
The common brake/clutch fluid
reservoir is filled with DOT 3 brake
fluid as indicated on the reservoir
cap. See Engine Compartment
Overview 0281 for reservoir
location.
How to Check and Add Fluid
Visually check the brake/clutch fluid
reservoir to make sure the fluid level
is at the MIN (minimum) line on the
front of the reservoir. The brake/
hydraulic clutch fluid system should
be closed and sealed.

Do not remove the cap to check the
fluid level or to top-off the fluid level.
Remove the cap only when
necessary to add the proper fluid
until the level reaches the MIN line.
Engine Air Cleaner/Filter
The engine air cleaner/filter is in the
engine compartment on the
passenger side of the vehicle. See
Engine Compartment Overview
0281.
When to Inspect the Engine Air
Cleaner/Filter
For intervals on changing and
inspecting the engine air cleaner/
filter, see Maintenance Schedule
0 364.
How to Inspect the Engine Air
Cleaner/Filter
Do not start the engine or have the
engine running with the engine air
cleaner/filter housing open. Before
removing the engine air cleaner/
filter, make sure that the engine air
cleaner/filter housing and nearby
components are free of dirt and
debris. Remove the engine air cleaner/filter. Lightly tap and shake
the engine air cleaner/filter (away
from the vehicle), to release loose
dust and dirt. Inspect the engine air
cleaner/filter for damage, and
replace if damaged. Do not clean
the engine air cleaner/filter or
components with water or
compressed air.
To inspect or replace the air cleaner/
filter:

{Warning
Operating the engine with the air
cleaner/filter off can cause you or
others to be burned. The air
cleaner not only cleans the air; it
helps to stop flames if the engine
backfires. Use caution when
working on the engine and do not
drive with the air cleaner/filter off.
Caution
If the air cleaner/filter is off, dirt
can easily get into the engine,
which could damage it. Always
have the air cleaner/filter in place
when driving.
Cooling System
The cooling system allows the
engine to maintain the correct
working temperature.
