With the A/C on, move the temperature knob to MAX

for maximum cooling. This setting also puts the system

in the recirculation mode and helps to maximize your air

conditioner’s performance and your vehicle’s fuel

economy. This setting also cools the air the fastest. After

the vehicle’s interior reaches a comfortable temperature,

move the temperature knob clockwise to place the air

conditioning system in the normal mode.

The heater works best if you keep your windows closed

while using it. On cold days, use the HEATER or

VENT/HEAT setting with the temperature knob in the

red area.

If you use the engine coolant heater before starting your

engine (in cold weather (20°F (-8OC) or lower), your

heating system will produce warmer air faster, to heat

the passenger compartment in cold weather.

The use of an engine coolant heater also reduces the

time it takes for the engine to reach normal operating

temperature, and shortens the time it takes the heater to

reach full output. For more information, see “Engine

Coolant Heater” in the Index.

Ventilation System

For mild outside temperature when little heating or

cooling is needed, use VENT to direct outside air

through your vehicle. Air will flow through the

instrument panel outlets.

Your vehicle’s ventilation system supplies outside

air to the inside

your vehicle when

is moving.

With the side windows closed, air will flow into the

front air inlet grilles, through the vehicle, and out the

air exhaust valves.

Outside air will also enter the vehicle when the heater or

the air conditioning fan is running, unless you have the

recirculation button pushed in. For more information

the recirculation button, see “Air Conditioning” earlier

in this section.
