position will cause fogging of the wind-
shield and side windows and the air
within the passenger compartment will
become stale.
In addition, prolonged use of the air
conditioning with the recirculated air
position selected, will result in excessive-
ly dry air in the passenger compart-
ment.
WARNING

operation in the recirculated air
position may allow humidity to
increase inside vehicle which may
fog the glass and obscure visibility.
Do not sleep in a vehicle with air
conditioning or heating system on.
It may cause serious harm or death
due to a drop in the oxygen level
and/or body temperature.
Continued climate control system
operation in the reciruclated air
position can cause drowsiness or
sleepiness, and loss of vehicle
control. Set the air intake control to
the outside (fresh) air position as

dure, and be careful to avoid damaging
other components.
Filter replacement1. Open the glove box and remove the
support rod.2. With the glove box open, remove the
