Engine Oil
If the CHECK OIL LEVEL message 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 3-60.
You should check your engine oil level regularly; this is
an added reminder.

Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 5-12for
location of engine air cleaner/®lter.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/®lter every 15, 000 miles
(25 000 km) and replace every 30, 000 miles
(50 000 km). If you are driving in dusty/dirty conditions,
inspect the ®lter at each oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/®lter, remove the ®lter from
the vehicle and lightly shake the ®lter to release
loose dust and dirt. If the ®lter remains caked with dirt, a
new ®lter is required.
To inspect or replace the ®lter, do the following:1. Loosen and remove both wing screws on the top of
the engine air cleaner/®lter cover.
2. Lift up the outboard side of the cover at an angle
while pulling toward you. This is necessary due to
the three tabs located on the rear of the cover.
