Rear Air Vents
To maximize airflow through the rear heater outlet, place
the left bucket seat in the second row in the forward
position (see “Adjusting Rear Seats” in the Index).
The vent behind the left rear seat is the cold air return
vent. Be sure to keep it free of obstructions.
Keep the area around the base of the center instrument
panel console, between and under the front seats, free of
objects that could obstruct airflow to the rear.
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 change the direction of
the airflow. 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 thumbwheel next to each outlet all the way
down. You can also stop outside air from entering the
vehicle by turning the fan to OFF and pushing the
RECIRCULATION button.
