M / F (Recirculation/Outside Air): Press this
button to switch between recirculation and outside
air modes. The indicator light comes on to show which
mode is being used. The recirculation mode recirculates
and helps to quickly cool the air inside the vehicle.
It can be used to prevent outside air and odors from
entering the vehicle. Press the auto button to have
the system select the best air delivery mode for
the temperature setting.
Recirculation is not available in the defrost mode and
automatically turns off 10 minutes after defog is selected.
This helps to limit window fogging in the vehicle.
Using recirculation for long periods of time could cause
the air inside the vehicle to become too dry or stuffy.
To prevent this from happening, after the air in the vehicle
has cooled, select outside air or press the auto button.
The outside air mode pulls fresh air from outside the
vehicle. Outside air is always selected in defrost mode to
prevent fogging.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window. It only works
when the ignition is in ON/RUN.
= (Rear Window Defogger): Press to turn the rear
window defogger on or off.
The rear window defogger stays on for about
15 minutes, before turning off if the vehicle is moving
at a slower speed. At higher speeds, the rear window
defogger may stay on continuously. With each additional
press, the defogger runs for about 10 minutes. The
defogger can also be turned off by turning off the engine.
The heated outside rearview mirrors turn on when the
rear window defogger button is on and helps to clear
fog or frost from the surface of the mirror. See Outside
Heated Mirrors on page 2-54.
Notice: Do not try to clear frost or other material
from the inside of the front windshield and rear
window with a razor blade or anything else that is
sharp. This may damage the rear window defogger
grid and affect your radio’s ability to pick up stations
clearly. The repairs wouldn’t be covered by your
warranty.
Heated and Ventilated Seats: Press to heat or
ventilate the seat. See Heated and Ventilated Seats
on page 1-7.
