Outlet Adjustment
Operation Tips

dse the air outlets located in the center and on the side
of your instrument panel to direct the airflow.
Your vehicle has air outlets that allow you to adjust the
direction and amount of airflow inside the vehicle.
Move the louvers up or down. Use the thumbwheel next
to or underneath the outlet to close the louvers. For
the most efficient airflow and temperature control, keep
the outlet in the fully opened position.
If your vehicle is equipped with rear seat outlets they
can be used to adjust airflow toward either seating area,
the floor, or upward. Move the center louver up or
down to direct the airflow.
Keep the hood and front air inlets 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.
Keep the air path under the front seats clear of
objects. This helps air to circulate throughout your
vehicle.
Adding outside equipment to the front of your vehicle,
such as hood-air deflectors, etc., may affect the
performance of the heating and air conditioning
system. Check with your dealer before adding
equipment to the outside of your vehicle.
