Climate Control System*
Using Automatic Climate Control
The automatic climate control system maintains the interior temperature you select.
The system also selects the proper mix of heated or cooled air that will as quickly as
possible, raise or lower the interior temperature to your preference.
Use the system when the engine is running.
1. Press the AUTO button.
2. Adjust the interior temperature using the driver’s side or passenger’s side
temperature control switch.
3. Press the ON/OFF button to cancel.1Using Automatic Climate Control
If any buttons are presse d while using the climate
control system in auto, the function of the button
that was pressed will take priority.
The AUTO indicator will go off, but functions
unrelated to the button th at was pressed will be
controlled automatically.
If ECON mode is selected, the fan may turn off.
To prevent cold air from bl owing in from outside, the
fan may operate at low speed for a while after the
AUTO button has been pressed.
Once you have set the de sired temperature, do not
use the temperature control switches more than
necessary.
Doing so may delay the time it takes to reach the set
temperature.
If the interior is very warm, you can cool it down
more rapidly by partial ly opening the windows,
turning the system on auto, and setting the
temperature to low. Change the fresh mode to
recirculation mode until the temperature cools down.
When you set the temperat ure to the lower or upper
limit, Lo or Hi is displayed.
Pressing the ON/OFF button switches the
climate control system be tween on and off. When
turned on, the system returns to your last selection.

Maintenance
Heating and Cooling System*/Climate Control System* Maintenance
Air Conditioning
To ensure proper and safe operation, the Society of Automotive Engineers (SAE
J2845) recommends that the refrigerant sy stem only be serviced by trained and
certified technicians.
Never repair or replace the air conditioning evaporator (cooling coil) with one
removed from a used or salvaged vehicle.
New replacement mobile air conditioning evaporators must be certified (and
labeled) as meeting SAE Standard J2842.
Dust and Pollen Filter
The heating and cooling system*/climate control system* is equipped with a dust
and pollen filter that collects pollen, dust, and other debris in the air. The
Maintenance Minder
TM messages will let you know when to replace the filter.
We recommend that you replace the dust and pollen filter sooner when using your
vehicle in areas with high concentrations of dust.

NOTICE
Vented refrigerant is harmful to the environment.
To avoid refrigerant from venting, never replace the
evaporator with one re moved from a used or
salvaged vehicle.
Refrigerant in your vehicle’s air conditioning system is
flammable and can be igni ted during servicing if
proper procedures are not followed.
