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:
.Always 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 on page 10‑9.
.Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
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 vehicle
must be on level ground. The
engine oil dipstick handle is a loop.
SeeEngine Compartment Overview
on page 10‑6 for the location of the
engine oil dipstick.
Obtaining an accurate oil level
reading is essential:
1. If the engine has been running recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.

vehicle towed to a dealer and have
it repaired before driving the vehicle
further.
Change the fluid and filter at the
intervals listed inMaintenance
Schedule on page 11‑3, and be sure
to use the transmission fluid listed in
Recommended Fluids and
Lubricants on page 11‑12.
How to Check Automatic
Transmission Fluid
Because this operation can be
difficult, it is recommended to have
this check done at your dealer,
which can monitor the transmission
temperature. The transmission fluid
level increases with temperature. To
obtain a highly accurate fluid level
check, the transmission temperature
must be measured.
If it is decided to check the fluid
level, be sure to follow all the
instructions here, or a false reading
on the dipstick may occur. Notice:
Too much or too little
fluid can damage the
transmission. Too much can
mean that some of the fluid could
come out and fall on hot engine
parts or exhaust system parts,
starting a fire. Too little fluid
could cause the transmission to
overheat. Be sure to get an
accurate reading if checking the
transmission fluid.
Wait at least 30 minutes with the
engine off, before checking the
transmission fluid level if the vehicle
has been driven:
.In hot weather, when outside
temperatures are above 32°C
(90°F).
.The vehicle is heavily loaded.
.At high speed for quite a while in
hot weather.
.In heavy traffic and hot weather.
.While pulling a trailer. After driving under these conditions,
a hot check can be performed. The
fluid should be hot, which is 71°C to
93°C (160°F to 200°F).
A cold fluid level check can be
performed after the vehicle has
been sitting for eight hours or more
with the engine off, but this is used
only as a reference. Let the engine
run at idle for five minutes if the
outside temperature is between
15°C to 32°C (60°F to 90°F). Should
the fluid level be low during this cold
check, the fluid must be checked
warm or hot before adding fluid.
If the outside temperature is colder
than 15°C (60°F) or hotter than
32°C (90°F), a cold check cannot be
performed.
A warm fluid level check can be
performed by driving the vehicle
under lightly loaded conditions and
outside temperatures between 10°C
to 27°C (50°F to 80°F). The vehicle
should be driven for at least 24 km
(15 mi) before performing a warm
check. Checking the fluid warm or

How to Add Automatic
Transmission Fluid
Refer toRecommended Fluids and
Lubricants on page 11‑12 to
determine what kind of transmission
fluid to use.
1. WARM Range
2. HOT Range
Using a funnel, add fluid down the
transmission dipstick tube only after
checking the transmission fluid
while it is warm or hot. A cold check
is used only as a reference. If the
fluid level is low, add only enough of
the proper fluid to bring the level up
to the middle of the WARM (1) or
HOT (2) range depending on the
ambient temperature and prior driving conditions. Refer to
“How to
Check Automatic Transmission
Fluid” earlier in this section for
instructions on driving to achieve
warm or hot transmission fluid.
It does not take much fluid,
generally less than 0.5 L (1 pt). Do
not overfill.
Notice: Use of the incorrect
automatic transmission fluid may
damage the vehicle, and the
damages may not be covered by
the vehicle warranty. Always use
the automatic transmission fluid
listed in Recommended Fluids
and Lubricants on page 11‑12.
.After adding fluid, recheck the
fluid level as described under
“How to Check Automatic
Transmission Fluid,” earlier in
this section.
.When the correct fluid level is
obtained, push the dipstick back
in all the way; then flip the
handle down to lock the dipstick
in place.
Engine Air Cleaner/Filter
The engine air cleaner/filter is near
the center of the engine
compartment. See Engine
Compartment Overview on
page 10‑6.

10-16 Vehicle Care
When to Inspect the Engine Air
Cleaner/Filter
Inspect or replace the air cleaner/
filter at the scheduled maintenance
intervals. SeeMaintenance
Schedule on page 11‑3. If 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 it to release loose
dust and dirt. If the filter remains
covered with dirt, a new filter is
required. Never use compressed air
to clean the filter.
To inspect or replace the engine air
cleaner/filter:
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. Use caution when
working on the engine and do not
drive with the air cleaner/filter off.
Notice: 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 you are driving.
Cooling System
The cooling system allows the
engine to maintain the correct
working temperature.

Engine Oil Change
When the CHANGE ENGINE OIL
SOON message displays, have the
engine oil and filter changed within
the next 1 000 km/600 mi. If driven
under the best conditions, the
engine oil life system might not
indicate the need for vehicle service for more than a year. The engine oil
and filter must be changed at least
once a year and the oil life system
must be reset. Your trained dealer
technician can perform this work.
If the engine oil life system is reset
accidentally, service the vehicle
within 5 000 km/3,000 mi since the
last service. Reset the oil life
system when the oil is changed.
