Automatic Operation
AUTO (Automatic):When this button is pressed
and the temperature is set, the system will
automatically control the inside temperature, the
air delivery mode, the air conditioning compressor
and the fan speed. AUTO will appear on the
display.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable
setting between 70°F (21°C) and 80°F (27°C).
An initial setting of 73°F (23°C) is suggested.
Choosing the warmest or coldest temperature
setting will not cause the system to heat or cool
any faster. If you set the system at the warmest
or coldest temperature setting, the system will
remain in manual mode at that temperature and
it will not go into automatic mode.
In cold weather, the system will start at
reduced fan speeds to avoid blowing cold air
into your vehicle until warmer air is available.
The system will start out blowing air at the oor
but may change modes automatically asthe vehicle warms up to maintain the chosen
temperature setting. 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. Wait for the system to regulate. This may take
from 10 to 30 minutes. Then adjust the
temperature, if necessary.
You can switch from English to metric units
through the Driver Information Center (DIC). See
DIC Controls and Displays on page 204for
more information.
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.
Do not cover the solar sensor located in the
center of the instrument panel, near the
windshield. For more information on the solar
sensor, see “Sensors” later in this section.

There is also a sensor located behind the front
bumper. This sensor reads the outside air
temperature and helps maintain the temperature
inside the vehicle. The outside temperature will be
displayed in the navigation system only when
the engine is running. Any cover on the front of the
vehicle could give a false reading of the
temperature.
If the outside temperature goes up, the display
temperature will not change until:
The vehicle’s speed is above 15 mph
(24 km/h) for ve minutes.
The vehicle’s speed is above 32 mph
(51 km/h) for two and one-half minutes.
These delays prevent false readings. If the
temperature goes down, the outside temperature
will be shown when you start the vehicle. If it
has been turned off for less than three hours, the
temperature will be recalled from the previous
vehicle operation.
There is also an inside temperature sensor
located to the left of the ignition button. The
automatic climate control system uses this sensor
to receive information, so if you block or cover
it, the system will not function properly.
Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate control
system is used properly. There are two modes to
clear fog or frost from your windshield. Use the
oor/defog mode to clear the windows of fog or
moisture and warm the passengers. Use defrost to
remove fog or frost from the windshield more
quickly.
-(Floor/Defog):Press the mode button until the
defog mode appears on the display. This mode
directs the air between the windshield, oor outlets
and side windows. When you select this mode,
the system turns off recirculation and runs the air
conditioning compressor unless the outside
temperature is near or below freezing.
1(Defrost):Press this button to direct most of
the air to the windshield, with some air directed
to the side windows. In this mode, the system will
automatically turn off the recirculation and run
the air conditioning compressor, unless the outside
temperature is near or below freezing. Do not
drive the vehicle until all the windows are clear.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
engine is running.
=(Rear Window Defogger):Press this button
to turn the rear window defogger on or off. Be
sure to clear as much snow from the rear window
as possible.
The rear window defogger will turn off about
10 minutes after the button is pressed when
traveling less than 30 mph (48 km/h). If turned
on again, the defogger will only run for about
ve minutes before turning off. The defogger can
also be turned off by pressing the button again
or by turning off the engine.The heated outside rearview mirrors will heat to
help clear fog or frost from the surface of the
mirrors when the rear window defogger is on.
The rear window defogger and heated mirrors are
automatically disabled when the retractable
hardtop is moving or down.
Notice:Do not use anything sharp on the
inside of the rear window. If you do, you could
cut or damage the warming grid, and the
repairs would not be covered by your warranty.
Do not attach a temporary vehicle license,
tape, a decal or anything similar to the
defogger grid.
