Passenger Compartment Air Filter
The passenger compartment air lter removes certain
particles from the air including pollen and dust particles.
Reductions in airow, which may occur more often in
dusty areas, indicate that the lter may need to be
replaced. SeeScheduled Maintenance on page 6-4
for information on how often to replace the lter.
Notice:Driving without a passenger compartment
air lter in place can cause water and small
particles, like paper and leaves, to be pulled into
your climate control system which may cause
damage to it. Make sure you always replace the
old lter with a new one.
The passenger compartment air lter is located on the
passenger side of the engine compartment near the
battery. SeeEngine Compartment Overview on
page 5-14.To check or replace the air lter:
1. Remove the cover retainer clips (A) from the
passenger compartment air lter cover.
2. Remove the cover.

Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 5-14for
the location of the engine air cleaner/lter.
Notice:If you spray water into the engine air
cleaner/lter intake and water enters the engine
air cleaner/lter housing, you could damage your
vehicle’s engine. The repairs would not be covered
by your warranty. Do not spray water into the
engine air cleaner/lter intake and/or housing.
If you are cleaning the vehicle with the hood open, take
care not to spray water directly near the lter opening
of the air cleaner, as shown in the illustration, as
this could damage the vehicle’s engine.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/lter at the MaintenanceII
intervals and replace them 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 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 engine air cleaner/lter:
