Engine Oil
If the CHECK OIL LEVEL light appears on the
instrument cluster, it means you need to check your
engine oil level right away.
For more information, see ªCHECK OIL LEVELº under
DIC Warnings and Messages on page 3-57.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It's a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick has
a ring handle and is
located on the passenger's
side of the vehicle. See
Engine Compartment
Overview on page 5-12for
more information on
location.

Engine Air Cleaner/Filter
SeeEngine Compartment
Overview on page 5-12for
location of engine air
cleaner/®lter and change
indicator (if equipped).
When to Inspect
If your vehicle is equipped with a ®lter change indicator
it lets you know when the ®lter needs to be replaced.
Inspect the air cleaner/®lter change indicator every
15,000 miles (25 000 km) and replace the ®lter if
necessary. Vehicles without a change indicator inspect
the air cleaner/®lter every 15,000 miles (25 000 km)
and replace the ®lter every 30,000 miles (50 000 km). If
you are driving in dusty/dirty conditions, inspect the
®lter or change indicator at each engine oil change.
How to Inspect
Locate the ®lter change indicator. When the change
indicator turns black or is in the red/orange ªchangeº
zone, replace the ®lter and reset the indicator. To
inspect the air cleaner/®lter, remove the ®lter from the
vehicle and lightly shake ®lter to release loose dust and
dirt. If the ®lter remains ªcakedº with dirt, a new ®lter
is required.
To inspect and replace the ®lter and reset the indicator
(if equipped), do the following:
The air cleaner/®lter assembly is located on the front
corner of the engine compartment on the passenger's
side of the vehicle.

If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed. See
Engine Oil on
page 5-15for information on resetting the system.
An Emission Control Service.
Lubricate chassis components with each engine oil
and ®lter change.
Lubricate the front suspension, ball joints, steering
linkage, transmission shift linkage and parking brake
cable guides. Ball joints should not be lubricated unless
their temperature is 10ÉF (-12ÉC) or higher, or they
could be damaged.
See the mileage intervals following for additional
services that may be performed with an engine oil
change and chassis lubrication. After the services are
performed, record the date, odometer reading and
who performed the service on the maintenance record
pages in Part E of this schedule.
