To place the entire system in automatic mode, do
the following:
1. Press the driver’s temperature knob to turn
the system on.
2. Adjust the temperature to a comfortable
setting.
Choosing the coldest or warmest temperature
will not cause the system to heat or cool
any faster.
In cold weather, the system will start at
reduced fan speeds to avoid blowing cold air
into your vehicle until warmer air is available.
Then, as the air warms, it will be delivered
through the instrument panel outlets. The
length of time needed for warm up will depend
on the outside temperature and the length
of time that has elapsed since your vehicle was
last driven.3. Adjust the PASS TEMP indicator that is
located below the temperature display. If
only the larger center bar is lit, the passenger
side will be adjust to the same temperature
setting as the driver side. Each bar that is lit to
the + side of the center bar indicates that
the passenger side will control to a warmer
setting than the driver side. Each bar lit to
the — side of the center bar indicates that the
passenger side will control to a cooler
setting than the driver side.
4. Wait for the system to regulate. This may take
from 10 to 30 minutes. Then adjust the
temperature as necessary.
5. To turn the system off, press the
passenger’s knob.

the button until the desired mode appears on
the display.
207

You may notice a slight change in engine
performance when the air-conditioning compressor
shuts off and turns on again. This is normal.
The system is designed to make adjustments to
help with fuel economy while still maintaining
the selected temperature.
On hot days, open the windows to let hot inside
air escape; then close them. This helps to reduce
the time it takes for your vehicle to cool down.
It also helps the system to operate more efficiently.
The air-conditioning system removes moisture
from the air, so you may sometimes notice a small
amount of water dripping underneath your
vehicle while idling or after turning off the engine.
This is normal.
Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity, or moisture, condensing on the cool
window glass. This can be minimized if the climate
controls system is used properly. There are two
modes to clear fog or frost from your windshield.
Use the defog mode to clear the windows of fog or
moisture and warm the passengers. Use the
defrost mode to remove fog or frost from
the windshield more quickly.Use the MODE button to select the defog mode.
-(Defog):This mode directs air to the
windshield and the oor outlets. When you select
this mode, the system turns off recirculation
and runs the air-conditioning compressor unless
the outside temperature is at or below freezing.
The recirculation mode cannot be selected while in
the defog mode.
Press the defrost button to select defrost.
0(Defrost):This mode directs most of the air to
the windshield and the side window outlets, with
some air directed to the oor outlets. In this mode,
the system will automatically turns off recirculation
and run the air-conditioning compressor, unless
the outside temperature is at or below freezing.
Recirculation cannot be selected while in the
defrost mode.
Do not drive the vehicle until all the windows are
clear.

INST ECONOMY (Instant Economy):Instant fuel
economy reects the fuel economy that the
vehicle has right now. Instant fuel economy varies
with your driving conditions, such as acceleration,
braking and the grade of the road being
traveled. Unlike average fuel economy, instant fuel
economy cannot be reset.
FUEL RANGE:The fuel range is an estimated
distance that your vehicle can travel on the
remaining fuel. The fuel economy used to calculate
the range is based on your driving history since
the last reset of the average speed.
FUEL USED:The fuel used display will show you
how much fuel has been used since the last
time it was reset. To reset the fuel used to zero,
press and hold the SET button while the fuel used

OIL LIFE LEFT HOLD SET TO RESET:This
message displays the current percentage of the oil
life by the engine oil life system. Be careful not
to reset this display other than when the oil
has been changed. See “How to Reset the Engine
Oil Life System” underEngine Oil Life System
on page 368for more information.
In addition to the engine oil life system monitoring
the oil life, additional maintenance is
recommended in the Maintenance Schedule in this
