Rear Air Outlets
The outlet behind the left rear seat is the cold
air return outlet. Be sure to keep it free from
obstructions. Also, keep the area around the base
of the center instrument panel console, between
and under the front seats, free of objects that could
also obstruct airow to the rear seating area.
For more information on how to use the main
climate control system, seeDual Climate Control
System on page 197. For information on
ventilation, seeOutlet Adjustment on page 200.
Passenger Compartment Air Filter
Passenger compartment air, both outside and
recirculated air, is routed through a passenger
compartment lter. The lter removes most
particles from the air, including dust particles.
Reductions in airow, which may occur more
quickly in dusty areas, indicate that the lter
needs to be replaced early. For how often to
change the air lter, seeScheduled Maintenance
on page 509.The access panel for the passenger compartment
air lter is located in the back of the glove box.
To replace the lter, do the following:
1. Pull the tab located on the outer access
panel up and out.

Checking Engine Oil
It is a good idea to check the 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 handle is a yellow loop.
SeeEngine Compartment Overview on page 410
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil
several minutes to drain back into the oil pan.
If you do not do this, the oil dipstick might
not show the actual level.
2. Pull out the dipstick and clean it with a paper
towel or cloth, then push it back in all the
way. Remove it again, keeping the tip down,
and check the level.

Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 410
for the location of the engine air cleaner/lter.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/lter at the MaintenanceII
intervals and replace it at the rst oil change
after each 50,000 mile (85 000 km) interval.SeeScheduled Maintenance on page 509for
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. Do not use
compressed air to clean the lter.
To inspect or replace the air cleaner/lter, do the
following:
1. Remove the two clamps on the duct.
2. Remove the duct.
3. Unlatch the two hooks on top of the engine air
cleaner/lter housing.
4. Inspect or replace the engine air cleaner/lter.
5. Align the tabs located on the bottom of the
panel with the slots at the bottom of the
housing.
