Comfort Controls
Flow-Through Ventilation System
Your vehicle’s flow-through 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 fro Int
Outside air will also enter the vehicle when the heater or the air
conditioning fan
is running, unless your optional air conditioner is in the
MAX mode. For more information see “MAX Button” in this section.
Ventilation Tips
0 Keep the hood and front air inlet free of ice, snow, or any other
obstruction (such
as leaves). The heater and defroster will work far
better, reducing the chance
of fogging the inside of your windows.
0 When you enter a vehicle in cold weather, turn the blower fan to HI 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.
0 Keep the air path under the front seats clear of objects. This helps air to
circulate throughout your vehicle.
