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 air conditioning
fan is running.
If the airflow seems very low when the fan is adjusted to
the highest setting regardless of the mode setting, your
passenger compartment air filter may need to be
replaced. See "Maintenance Schedule" or "Passenger
Compartment Air Filter" in the Index.
Adjust the direction
of airflow by moving
the vents.
