For diesel engine vehicles, see “Engine Oil” in the
DURAMAX®Diesel manual.
Checking Engine Oil
It is a good idea to check the engine oil level at each
fuel fill. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 6-14for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If this is not done, the
oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.
6-15

If the message comes back on when the vehicle is
started, the engine oil life system has not reset. Repeat
the procedure. If it still does not reset, see your
dealer/retailer for service.
What to Do with Used Oil
Used engine oil contains certain elements that can 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
filter 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. Recycle it by taking it to a
place that collects used oil.
Engine Air Cleaner/Filter
If your vehicle has the DURAMAX Diesel engine, see
the DURAMAX Diesel manual for more information.
The engine air cleaner/filter is located near the center of
the engine compartment. SeeEngine Compartment
Overview on page 6-14for more information on location.
6-19

When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter at the MaintenanceII
intervals and replace it at the first oil change after each
50,000 mile (80 000 km) interval. SeeScheduled
Maintenance on page 7-3for more information. If you
are driving in dusty/dirty conditions, inspect the filter
at each engine oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/filter, remove the filter from
the vehicle and lightly shake the filter to release
loose dust and dirt. If the filter remains caked with dirt, a
new filter is required. Never use compressed air to
clean the filter.
To inspect or replace the engine air cleaner/filter, do the
following:
1. Unhook the retainer clips and remove the cover.
2. Lift the filter out of the engine air cleaner/filter
housing. Care should be taken to dislodge as
little dirt as possible.
3. Clean the engine air cleaner/filter housing.
4. Inspect or replace the engine air cleaner/filter. Make
sure that the filter fits properly into the housing.5. Reinstall the cover and fasten the retaining clips.
{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. If it is not there and
the engine backfires, you could be burned. Do not
drive with it off, and be careful working on the
engine with the air cleaner/filter off.
Notice:If the air cleaner/lter is off, a backre can
cause a damaging engine re. And, dirt can
easily get into the engine, which will damage it.
Always have the air cleaner/lter in place when you
are driving.

•Tire inflation check. SeeInation - Tire Pressure on
page 6-63.
•Tire wear inspection. SeeTire Inspection and
Rotation on page 6-69.
•Rotate tires. SeeTire Inspection and Rotation on
page 6-69.
•Fluids visual leak check (or every 12 months,
whichever occurs first). A leak in any system must
be repaired and the fluid level checked.
•Engine air cleaner filter inspection (vehicles driven
in dusty conditions only). SeeEngine Air
Cleaner/Filter on page 6-19.
•Brake system inspection (or every 12 months,
whichever occurs first).
MaintenanceII
•Perform all services described in MaintenanceI.
•Steering and suspension inspection. Visual
inspection for damaged, loose, or missing parts or
signs of wear.
•Lubricate the front suspension, kingpin bushings,
steering linkage, and rear driveline center splines.
•Engine cooling system inspection. Visual inspection
of hoses, pipes, fittings, and clamps and
replacement, if needed.
•Windshield wiper blade inspection for wear,
cracking, or contamination and windshield and wiper
blade cleaning, if contaminated. SeeWindshield
and Wiper Blades on page 6-101. Worn or damaged
wiper blade replacement. SeeWindshield Wiper
Blade Replacement on page 6-54.
•Body hinges and latches, key lock cylinders, folding
seat hardware, and rear compartment hinges,
linkage, and handle pivot points lubrication. See
Recommended Fluids and Lubricants on page 7-11.
More frequent lubrication may be required when
vehicle is exposed to a corrosive environment.
Applying silicone grease on weatherstrips with a
clean cloth makes them last longer, seal better, and
not stick or squeak.
•Restraint system component check. SeeChecking
the Restraint Systems on page 2-79.
•Automatic transmission fluid level check and adding
fluid, if needed. SeeAutomatic Transmission Fluid
(4-Speed Transmission) on page 6-20or
Automatic Transmission Fluid (6-Speed
Transmission) on page 6-23.
•All-wheel drive vehicles: Transfer case fluid level
check and adding fluid, if needed.
•Engine air cleaner filter inspection. SeeEngine Air
Cleaner/Filter on page 6-19.

•Automatic transmission fluid change (severe
service) for vehicles mainly driven in heavy
city traffic in hot weather, in hilly or mountainous
terrain, when frequently towing a trailer, or used for
taxi, police, or delivery service. SeeAutomatic
Transmission Fluid (4-Speed Transmission)
on page 6-20orAutomatic Transmission Fluid
(6-Speed Transmission) on page 6-23.
•All-wheel drive only: Transfer case fluid change
(severe service) for vehicles mainly driven when
frequently towing a trailer, or used for taxi, police, or
delivery service. Check vent hose at transfer
case for kinks and proper installation. Check to be
sure vent hose is unobstructed, clear, and free
of debris. During any maintenance, if a powerwasher is used to clean mud and dirt from the
underbody, care should be taken to not directly
spray the transfer case output seals. High pressure
water can overcome the seals and contaminate
the transfer case fluid. Contaminated fluid will
decrease the life of the transfer case and should be
replaced.
•Evaporative control system inspection. Check all
fuel and vapor lines and hoses for proper hook-up,
routing, and condition. Check that the purge
valve, if the vehicle has one, works properly.
Replace as needed.An Emission Control Service.
The U.S. Environmental Protection Agency or
the California Air Resources Board has determined
that the failure to perform this maintenance item
will not nullify the emission warranty or limit
recall liability prior to the completion of the vehicle’s
useful life. We, however, urge that all recommended
maintenance services be performed at the
indicated intervals and the maintenance be
recorded.
