To replace the passenger
compartment air filter:
1. Turn the ignition to ON/RUN with
the engine off.
2. Turn on the windshield wipers
and turn the ignition off again
when the wipers are straight up

screen. The passenger
compartment air filter is under
the screen.
3. Open the hood to access the
engine compartment. See Hood
on page 10‑4 for more
information.
4. Remove the three screws that
hold the screen in place and lift
off the screen by lifting and
sliding it toward the center of the
vehicle.
5. Pull out on the two tabs on each
end of the filter cover.
6. Lift the filter cover off by pulling
it straight up.
7. Remove the old filter and insert
a new one.
