Scheduled Maintenance on page 6-4.
#(Air Conditioning):Press this button to override the
automatic system and turn the air conditioning system on
or off. When in AUTO, the air conditioning compressor
will come on automatically, as necessary.
The air conditioning system removes moisture from the
air, so a small amount of water might drip underneath the
vehicle while idling or after turning off the engine. This is
normal.
M/F(Recirculation/Outside Air):Press this
button to switch between recirculation and outside air.
Whenever the button is pressed, the indicator light
comes on for the mode being used. The recirculation
mode recirculates air inside the vehicle. It can be used
to prevent outside air and odors from entering the
vehicle or to help cool the air inside the vehicle more
quickly. Press the auto button to have the system select
the best air delivery mode for your temperature setting.
Recirculation is not available in the defrost mode and
automatically turns off 10 minutes after defog is selected.
This helps to limit window fogging in the vehicle.
Using recirculation for long periods of time could cause
the air inside the vehicle to become too dry or stuffy.
To prevent this from happening, after the air in the vehicle
has cooled, select outside air or press the auto button.
The outside air mode pulls fresh air from outside the
vehicle. Outside air is always selected in defrost mode to
prevent fogging.

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
from the 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.
HG(Mode):Press the mode buttons until defog
appears on the display.
-(Defog):This mode directs the air between the
windshield, oor outlets and side windows. When this
mode is selected, the system turns off recirculation and
runs the air-conditioning compressor unless the outside
temperature is at or below freezing. If recirculation mode
is selected while in defog mode, it will be cancelled after
10 minutes.
0(Defrost):Pressing defrost directs most of the air
to the windshield, with some air directed to the side
windows. In this mode, the system automatically turns off
recirculation and runs the air-conditioning compressor,
unless the outside temperature is at or below freezing.
This mode may also cause the fan speed and air
temperature to increase.
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
ignition is in ON/RUN.
=(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 turns off about 15 minutes
after the button is rst pressed if the vehicle is moving
at slower speeds. At higher speeds, the rear window
defogger may stay on continuously. With each additional
press, the defogger runs for about 10 minutes.
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 mirror when
the rear window defogger button is on. SeeOutside
Heated Mirrors on page 2-51.
Notice:Do not try to clear frost or other material
from the inside of the front windshield and rear
window with a razor blade or anything else that is
sharp. This may damage the rear window defogger
grid and affect your radio’s ability to pick up
stations clearly. The repairs wouldn’t be covered by
your warranty.

Driver Information Center (DIC)
The Driver Information Center (DIC) gives you the
status of many of your vehicle’s systems. The DIC is
also used to display warning/status messages.
All messages appear in the DIC display located at the
bottom of the instrument panel cluster. The DIC buttons
are located on the instrument panel, next to the
steering wheel.
The DIC comes on when the ignition is on. After a short
delay, the DIC displays the information that was last
displayed before the engine was turned off.
The top line of the DIC display shows the DIC
information. The bottom line of the DIC display shows
the compass. The compass displays in the trip/fuel
menus and in some vehicle information menus.
If a problem is detected, a warning message appears
on the display. Take any message that appears on
the display seriously and remember that clearing
the message only makes the message disappear,
and does not correct the problem.

The Driver Information
Center (DIC) has different
displays which can be
accessed by pressing the
DIC buttons located on
the instrument panel, next
to the steering wheel.

DIC Compass
Your vehicle may have a compass in the Driver
Information Center (DIC).
Compass Zone
The zone is set to zone eight upon leaving the factory.
Your dealer/retailer will set the correct zone for your
location.
Under certain circumstances, such as during a long
distance cross-country trip or moving to a new state
or province, it will be necessary to compensate for
compass variance by resetting the zone through the
DIC if the zone is not set correctly.
Compass variance is the difference between the earth’s
magnetic north and true geographic north. If the
compass is not set to the zone where you live, the
compass may give false readings. The compass must
be set to the variance zone in which the vehicle is
traveling.

DIC Warnings and Messages
Messages are displayed on the DIC to notify the driver
that the status of the vehicle has changed and that
some action may be needed by the driver to correct the
condition. Multiple messages may appear one after
another.
Some messages may not require immediate action, but
you can press any of the DIC buttons on the instrument
panel to acknowledge that you received the messages
and to clear them from the display.
Some messages cannot be cleared from the DIC
display because they are more urgent. These messages
require action before they can be cleared. You should
take any messages that appear on the display seriously
and remember that clearing the messages will only
make the messages disappear, not correct the problem.
The following are the possible messages that can be
displayed and some information about them.
Accessory Mode Active
If your vehicle has the keyless access system, this
message displays when the accessory mode is active.
SeeIgnition Positions (Key Access) on page 2-32

The following conditions may cause this message
to appear:
Driver-added equipment plugged into the accessory
power outlet on the center console is causing
interference. Examples of these devices are cell
phones and cell phone chargers, two-way radios,
power inverters, or similar items. Try moving
the keyless access transmitter away from these
devices when starting the vehicle. In addition,
PDA devices and remote garage and gate openers
may also generate Electromagnetic Interference
(EMI) that may interfere with the keyless access
transmitter. Do not carry the keyless access
transmitter in the same pocket or bag as these
devices.
The vehicle is experiencing Electromagnetic
Interference (EMI). Some locations, such as
airports, automatic toll booths, and some gas
stations have EMI elds which may interfere with
