remove fog from the rear window.

the rear window defogger
on or off

know that the rear window defogger is activated.
The rear window defogger will turn off approximately 10
minutes after the button is pressed. If you need
additional warming time, press the button again.
Notice: Don't use a razor blade or something else
sharp on the inside of the rear window. If you
do, you could cut or damage the defogger and the
repairs would not be covered by your warranty.

Outlet Adjustment
Use the air outlets located in the center and on the side
of your instrument panel to direct the airflow.
Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use the vent setting to direct outside
air through your vehicle.
Your vehicle's ventilation system supplies outside air to
the inside of your vehicle when it is moving. With the
side windows closed, air will flow into the front air inlet
grilles, through the vehicle and out the air exhaust
valves.
Outside air will also enter the vehicle when the heater
or the air conditioning compressor is running, unless you
have the recirculation button pushed in.
