Engine Air Cleaner/Filter
SeeEngine Compartment
Overview on page 5-12for
location of engine air
cleaner/filter and change
indicator (if equipped).
When to Inspect
If your vehicle is equipped with afilter change indicator
it lets you know when thefilter needs to be replaced.
Inspect the air cleaner/filter change indicator every
15,000 miles (25 000 km) and replace thefilter if
necessary. Vehicles without a change indicator inspect
the air cleaner/filter every 15,000 miles (25 000 km)
and replace thefilter every 30,000 miles (50 000 km). If
you are driving in dusty/dirty conditions, inspect the
filter or change indicator at each engine oil change.
How to Inspect
Locate thefilter change indicator. When the change
indicator turns black or is in the red/orange“change”
zone, replace thefilter and reset the indicator. To
inspect the air cleaner/filter, remove thefilter from the
vehicle and lightly shakefilter to release loose dust and
dirt. If thefilter remains“caked”with dirt, a newfilter
is required.
To inspect and replace thefilter and reset the indicator
(if equipped), do the following:
The air cleaner/filter 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. SeeEngine Oil on
page 5-16for information on resetting the system.
An Emission Control Service.
Lubricate chassis components with each engine oil
and filter change.
Lubricate the front suspension, ball joints, steering
linkage, transmission shift linkage, transfer case shift
linkage and parking brake cable guides. Ball joints
should not be lubricated unless their temperature is
10°F(−12°C) 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
