Engine Air Cleaner/Filter
The engine air cleaner/lter is
located in the engine compartment
on the passenger side of the
vehicle. SeeEngine Compartment
Overview on page 5-10for more
information on location.
When to Inspect the Engine
Air Cleaner/Filter
Inspect the air cleaner/lter at the
MaintenanceIIintervals and replace
it at the rst oil change after each
50,000 mile (80 000 km) interval.SeeScheduled Maintenance on
page 6-4for 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 or replace the engine air
cleaner/lter:
1. Unfasten the clips that hold the
cover on and remove the cover.
2. Lift out the engine air
cleaner/lter.
3. Inspect or replace the air lter.
SeeMaintenance Replacement
Parts on page 6-14to
determine which lter to use.
4. Reinstall the engine air
cleaner/lter cover. Fasten the
clips to hold the cover in place.
{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 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. 3.7 L shown (5.3 L similar)

Automatic Transmission
Fluid
When to Check and Change
Automatic Transmission Fluid
A good time to check the automatic
transmission uid level is when
the engine oil is changed.
Change the uid and lter at the
intervals listed inAdditional
Required Services on page 6-6, and
be sure to use the transmission
uid listed inRecommended Fluids
and Lubricants on page 6-12.
How to Check Automatic
Transmission Fluid
Because this operation can be a
little difficult, you may choose
to have this done at the
dealer/retailer service department.
If adding it yourself, be sure to follow
all the instructions here, or there
could be a false reading on the
dipstick.Notice:Too much or too little
uid can damage your
transmission. Too much can
mean that some of the uid could
come out and fall on hot engine
parts or exhaust system parts,
starting a re. Too little uid
could cause the transmission to
overheat. Be sure to get an
accurate reading if you check
your transmission uid.
Wait at least 30 minutes before
checking the transmission uid level
if you have been driving:
When outside temperatures are
above 90°F (32°C).
At high speed for quite a while.
In heavy traffic — especially
in hot weather.
While pulling a trailer.
To get the right reading, the uid
should be at normal operating
temperature, which is 180°F to
200°F (82°C to 93°C).Get the vehicle warmed up by
driving about 15 miles (24 km) when
outside temperatures are above
50°F (10°C). If it is colder than
50°F (10°C), drive the vehicle
in 3 (Third) until the engine
temperature gage moves and then
remains steady for 10 minutes.
A cold uid check can be made 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 ve minutes if outside
temperatures are 50°F (10°C) or
more. If it is colder than 50°F (10°C),
the engine might have to idle
longer. Should the uid level
be low during this cold check,
check the uid hot before adding
uid. Checking the uid hot gives
a more accurate reading of the
uid level.
5-18 Service and Appearance Care

It does not take much uid,
generally less than one pint (0.5 L).
Do not overll.
Notice:Use of the incorrect
automatic transmission uid may
damage the vehicle, and the
damages may not be covered
by the vehicle’s warranty. Always
use the automatic transmission
uid listed inRecommended
Fluids and Lubricants on
page 6-12.
After adding uid, recheck the
uid level as described under
“How to Check Automatic
Transmission Fluid,” earlier
in this section.
When the correct uid level is
obtained, push the dipstick
back in all the way; then ip
the handle down to lock
the dipstick in place.
Manual Transmission
Fluid
When to Check
A good time to check the manual
transmission uid is when the
engine oil is changed. However,
the uid in the manual transmission
does not require changing.
How to Check
Because this operation can be a
little difficult, you may choose
to have this done at your GM
dealer/retailer service department.
If doing it yourself, be sure to follow
all the instructions here, or there
could be a false reading.Notice:Too much or too little
uid can damage your
transmission. Too little uid
could cause the transmission to
overheat. Be sure to get an
accurate reading if you check
your transmission uid.
To check the uid:
1. Park the vehicle on a level
surface, then shut the engine off.
Let the vehicle sit until the
transmission case is cool enough
to touch.
2. Remove the ller plug.

Maintenance Schedule 6-1

Scheduled Maintenance
When the CHANGE OIL message
displays in the Driver Information
Center (DIC), service is required for
the vehicle. SeeDIC Warnings
and Messages on page 3-37. Have
the vehicle serviced as soon as
possible within the next 600 miles
(1 000 km). It is possible that, if
driving under the best conditions,
the engine oil life system may
not indicate that vehicle service is
necessary for over a year. However,
the engine oil and lter must be
changed at least once a year and
at this time the system must be
reset. Your dealer/retailer has
trained service technicians who will
perform this work using genuine
parts and reset the system.If the engine oil life system is ever
reset accidentally, service the
vehicle within 3,000 miles
(5 000 km) since the last service.
Remember to reset the oil life
system whenever the oil is changed.
SeeEngine Oil Life System on
page 5-15for information on
the Engine Oil Life System and
resetting the system.
When the CHANGE OIL message
appears, certain services, checks,
and inspections are required.
Required services are described in
the following for “MaintenanceI”
and “MaintenanceII.” Generally, it is
recommended that the rst service
be MaintenanceI, the second
service be MaintenanceII, and then
alternate MaintenanceIand
MaintenanceIIthereafter. However,
in some cases, MaintenanceII
may be required more often.MaintenanceI—Use
MaintenanceIif the CHANGE
OIL message displays within
10 months since the vehicle was
purchased or MaintenanceII
was performed.
MaintenanceII—Use
MaintenanceIIif the previous
service performed was
MaintenanceI. Always use
MaintenanceIIwhenever the
message displays 10 months or
more since the last service or if the
message has not come on at all
for one year.
