Engine Air Cleaner/Filter
SeeEngine Compartment
Overview on page 5-10for
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.
Vehicles with a restriction indicator, inspect the air
cleaner/®lter at every oil change and replace the ®lter
when the indicator tells you to. Vehicles without a
change indicator, inspect the air cleaner/®lter at every
oil change and replace it at the ®rst oil change after
25,000 miles (40 000 km).
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.

It is also important to check your oil regularly and keep
it at the proper level.
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 5-16for information on resetting the system.
An Emission Control Service.
Lubricate chassis components with each engine oil
and ®lter change. Vehicles used under severe
commercial operating conditions require lubrication
on a regular basis every 3,000 miles (5 000 km).
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.
