Air Conditioning

Before using your vehicle’s air conditioning, open the

windows to clear the vehicle of hot air. This reduces the

time it takes for your vehicle to cool down. Then keep

your windows closed for the air conditioner to work at

its best.

You can use MAX A/C with the temperature knob in

the blue area when it’s really hot outside and you need

to cool the inside air quickly. MAX A/C lets in only a

little air from the outside.

If you first use MAX A/C, you can then use A/C with

the temperature knob in the blue area as soon as the

vehicle has cooled down, so outside air will be going

through your vehicle.

If your vehicle has rear air conditioning, setting it on LOW

may enhance the front air conditioning performance by

allowing trapped refrigerant in the rear lines to circulate.

The rear air conditioning system will only send cooled

air if the front system is on. It can still be used to

circulate air, even if the front system is off.

When the air conditioning, defrost or blend is on, you

may notice a slight increase or decrease in engine speed,

due to compressor operation. This is normal because the

system is designed to cycle the compressor on and off to

maintain the desired temperature.

Heating

On cold days, use the floor setting with the temperature

knob in the red area. Outside air will be brought in

through the floor ducts. The heater works best if you

keep your windows closed while using it.

If you use the optional engine coolant heater before

starting your engine, your heating system will produce

warmer air faster to heat the passenger compartment in

cold weather. See “Engine Coolant Heater” in the Index.

Defrosting

Use defrost to remove fog or ice from the windshield

quickly in extremely cold conditions. The temperature

knob should be in the red area and the fan control

toward high. The air conditioning compressor may

operate in this setting to dehumidify the air.

The blend setting is useful for cold weather with a large

number of passengers or very humid conditions to help

keep the windshield clear.
