You will find air outlets in the center and on the sides of
your instrument panel.
You can direct the airflow side to side by moving the
sliding levers. The outlet louvers can also be tilted up
and down. To control the amount of airflow through the
outlets, turn the thumbwheel.
Ventilation Tips
D Keep the hood and the area around the windshield
wipers free of ice, snow or any other obstruction,
such as leaves. The heater and defroster will work
better, reducing the chance of fogging the inside
of your windows.
D Keep the air path under the front seats clear
of objects to help air circulate throughout
your vehicle.
D When an objectionable odor outside the vehicle is
encountered, the recirculation setting can prevent the
odor from being drawn into the vehicle through the
ventilation system. For example, this usage of
recirculation can be helpful when driving through a
long tunnel with poor ventilation. However,
extended use of recirculation in cold or cool
weather can cause window fogging.
