Passenger Compartment Air Filter
Passenger compartment air, both outside air
and recirculated air, is routed through a passenger
compartment lter. The lter removes certain
particles from the air, including pollen and dust
particles. Reductions in airow, which may
occur more quickly in dusty areas, indicate that
the lter needs to be replaced early.
The lter should be replaced as part of routine
scheduled maintenance. SeeScheduled
Maintenance on page 393for replacement
intervals. See your dealer for details on changing
the lter. To nd out what type of lter to use,
seeNormal Maintenance Replacement Parts on
page 405.To access the passenger compartment air lter
you must go through the glove box.
1. Open the glove box and remove all articles
from the inside.
2. Release the glove box stops by pushing them
both outward to let the glove box drop open
completely.

Oil Pressure Light
If you have a low engine
oil pressure problem,
this light will stay on after
you start your engine, or
come on when you are
driving.
This indicates that your engine is not receiving
enough oil.
The engine could be low on oil, or could have
some other oil problem. Have it xed immediately.
The oil light could also come on in three other
situations:
When the ignition is on but the engine is not
running, the light will come on as a test to
show you it is working, but the light will go out
when you turn the ignition to START. If it
does not come on with the ignition on,
you may have a problem with the fuse or bulb.
Have it xed right away.
If you are idling at a stop sign, the light may
blink on and then off.
If you make a hard stop, the light may come
on for a moment. This is normal.
{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become so
hot that it catches re. You or others could
be burned. Check your oil as soon as
possible and have your vehicle serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.

In addition to the engine oil life system monitoring
the oil life, additional maintenance is
recommended in the Maintenance Schedule in this
manual. SeeEngine Oil on page 299and

Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 298
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. See
Scheduled Maintenance on page 393for 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. Never use
compressed air to clean the lter.
Because this operation can be a little difficult, you
may choose to have this done at the dealership
service department.
To inspect or replace the lter, do the following:
1. Disconnect the MAF sensor, PCV hose,
and both ducts.
2. Pull the entire system from the top of the
engine.
3. Flip the system over and place it on a soft,
non-abrasive surface.
4. Remove the screws that hod the housing and
cover together and lift off the housing.
5. Inspect or replace the engine air cleaner/lter.
6. Reverse the steps to reinstall the system.
Be sure to reinstall the housing tightly.
