Ventilation System
Your vehicle’s flow - through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the fan is running.
Your vehicle has air outlets that allow you to adjust the
direction and amount of airflow inside the vehicle. Push
the outlet up or down to direct airflow to your
preference. Increase or reduce the amount of airflow by
opening and closing the louvers. Opening and closing
the louvers will also direct airflow from side to side.
The air - flow through the vents can be shut off
completely by turning the thumb - wheel next to each
outlet all the way down. You can also stop outside air
from entering by turning the fan to OFF and pushing the
RECIRCULATION button.
Ventilation Tips
D Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). This will
allow the heater and defroster to work much better,
reducing the chance of fogging the inside of
your windows.
D When you enter a vehicle in cold weather, turn the
blower fan to its highest setting “5” for a few
moments before driving off. This helps clear the
intake ducts of snow and moisture, and reduces the
chance of fogging the inside of your windows.
D Keep the area around the base of the center
instrument panel console and the air path under the
front seats clear of objects. This helps air to circulate
throughout your vehicle.
D In cold weather, operating the system in the
OUTSIDE AIR mode will improve the time it takes
to warm the vehicle.
