Accessory Power Outlet(s)
The accessory power outlets enable power
electrical equipment such as a cellular telephone
or a CB radio to be used inside the vehicle.
Your vehicle has 12-volt outlets. One outlet is
located on the center console below the climate
controls. There may be another outlet located
inside the center storage console or in the ip and
fold console.
Open the cover to use the outlet. Be sure to close
the cover when the outlet is not in use.
Notice:Adding any electrical equipment to
your vehicle may damage it or keep other
components from working as they should. The
repairs would not be covered by your warranty.
Do not use equipment exceeding maximum
amperage rating of 20 amperes. Check with
your dealer before adding electrical equipment.Certain power accessory plugs may not be
compatible to the power accessory outlet and
could result in blown vehicle or adapter fuses.
If you experience a problem, see your dealer.
Notice:Improper use of the power outlet can
cause damage not covered by your warranty.
Do not hang any type of accessory or
accessory bracket from the plug because the
power outlets are designed for accessory
power plugs only.
Notice:Leaving electrical equipment plugged
in for an extended period of time while the
vehicle is off will drain the battery. Power is
always supplied to the outlets. Always unplug
electrical equipment when not in use and
do not plug in equipment that exceeds
the maximum 20 ampere rating.
When adding electrical equipment, be sure to
follow the proper installation instructions included
with the equipment.

Ashtray(s) and Cigarette Lighter
Your vehicle may have a removable ashtray and
cigarette lighter. The cigarette lighter may be
located under the climate control system.
The removable ashtray can be placed into the
front console cupholder.
Notice:If you put papers, pins, or other
ammable items in the ashtray, hot cigarettes
or other smoking materials could ignite
them and possibly damage your vehicle.
Never put ammable items in the ashtray.
To use the cigarette lighter, push it in all the way,
and let go. When the heating element is ready,
it will pop back out by itself.
Notice:Holding a cigarette lighter in while it is
heating will not allow the lighter to back away
from the heating element when it is hot. Damage
from overheating may occur to the lighter or
heating element, or a fuse could be blown. Do
not hold a cigarette lighter in while it is heating.
Do not use equipment exceeding maximum
amperage rating of 20 amperes.
Climate Controls
Climate Control System
With this system you can control the heating,
cooling and ventilation for your vehicle.
If your vehicle has the remote start feature and
it is activated, the climate control system will
automatically cool the vehicle if the temperature is
greater than 90°F (32°C) and heat the vehicle if the
temperature is below 37°F (3°C). If the temperature
is between 37°F (3°C) and 90°F (32°C), the last
control setting selected when the engine was
running will be used. Normal operation and the last
setting of the climate control system will return after
the key is turned to the RUN position.
168

Operation
OFF:Turn the left knob to this position to turn the
climate control system off.
9(Fan):Turn the knob by this symbol, located
on the left side of the climate control panel,
clockwise or counterclockwise to increase or
decrease the fan speed. The fan speed will be
temporarily reduced between the transition
to a new mode. The fan will resume the original
speed when the transition to the new mode
is complete.
Temperature Control:Turn the center knob
clockwise or counterclockwise to increase
or decrease the temperature inside your vehicle.Use the right knob to select from the
following modes:
H(Vent):This mode directs outside air to the
instrument panel outlets. If driving in city
traffic, and the vehicle is stopped and idling, or the
weather is hot, turning on the recirculation
mode helps to prevent the air inside the vehicle
from becoming stale. After ve minutes recirculate
will allow some outside air into the vehicle.
)(Bi-Level):This mode directs half of the air to
the instrument panel outlets, and the remaining
air to the oor outlets. Some air may be directed
toward the windshield. Slightly cooler air is directed
to the instrument panel outlets and warmer air is
directed to the oor outlets.
6(Floor):This mode directs most of the air to
the oor outlets with some air directed toward
the side window outlets and a little air directed to
the windshield.
In this mode, the system will automatically use
outside air. The air conditioning compressor will be
engaged unless the outside temperature is 40°F
(4°C) or below.
169

Defogging and Defrosting
Fog on the inside of the vehicle is a result of high
humidity causing moisture to condense on the
cool window glass. This can be minimized if the
climate control system is used properly. There are
two modes to clear frost or fog from the windshield.
Use the defog mode to clear the windows of
condensation and to warm the vehicle’s occupants.
Use the defrost mode to remove frost or
condensation from the windshield quickly.
See “Rear Window Defogger” later in this section
for information on clearing the rear window of
fog or ice.
Turn the right knob to select the defog or
defrost mode.
Do not drive the vehicle until all windows
are clear.
-(Defog):This mode directs half of the air to the
windshield and the side window outlets and half to
the oor outlets. When you select this mode, the
system turns recirculation off and runs the air
conditioning compressor unless the outside
temperature is near or below freezing. Pressing the
recirculation button will have no effect other than
turning on the indicator light while in defog mode.
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. When
you select this mode, the system turns
recirculation off and runs the air conditioning
compressor unless the outside temperature is near
or below freezing. Pressing the recirculation
button will have no effect other than turning on the
indicator light while in defrost mode.
171

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear):Press the button to turn the rear
window defogger on or off. An indicator light below
the button will come on to let you know that the
rear window defogger is activated.
The rear window defogger will only work when the
ignition is in RUN. The rear window defogger
will stay on for about 20 minutes after the button is
pressed. If turned on again, the defogger will
only run for about 20 minutes before turning off.
The defogger can also be turned off by pressing
the button again or by turning off the engine.
Do not drive the vehicle until all windows are clear.
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.
Dual Automatic Climate Control
System
With this system you can control the heating,
cooling, and ventilation for the vehicle.
172

Automatic Operation
AUTO (Automatic):Press the AUTO button for
automatic control of the inside temperature, the air
delivery mode, and the fan speed. There might
be a delay of two to three minutes before the fan
comes on when the automatic operation is
used in cold weather. For the automatic system to
function, the temperature must be set between
61°F (15°C) and 89°F (32°C).
1. Adjust the temperature to a comfortable
setting.
2. Press the PASS button or the up or down
arrows on the passenger side to turn the
passenger temperature set on and off. When
turned on, the passenger temperature will
be the same as the driver setting. Press the
up or down arrow on passenger side to adjust
the passenger temperature setting.
When the passenger’s temperature set is off,
the passenger display will be off and the
driver’s set temperature will be for the driver
and passenger.In cold weather, the system will start at
reduced fan speeds to avoid blowing cold air
into the vehicle until warmer air is available.
The system will start out blowing air at the oor
but may change modes automatically as the
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 the 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.
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.
4. Press OFF to turn the climate control system
off. Only the rear defog and heated seats will
function. Press AUTO or any other button
except the heated seats or rear defog to turn
the climate control system back on.

operation and places the system in manual or
semi-automatic mode. Press the AUTO button to
return to automatic operation. If the airow seems
low when the fan is at the highest setting, the
passenger compartment air lter may need to be
replaced. For more information seePassenger
Compartment Air Filter on page 178andScheduled
Maintenance on page 462.
174

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 this button to direct the
air between the windshield, oor outlets and
side windows. When you select this mode, the
system turns recirculation off and runs the
air conditioning compressor unless the outside
temperature is near or below freezing. Pressing
the recirculation button will have no effect
other than turning on the indicator light while in
oor/defog mode.
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. Pressing the
recirculation button will have no effect other than
turning on the indicator light while in defrost mode.
Do not drive the vehicle until all windows are clear.
Sensors
The solar sensor on the vehicle monitors the solar
heat and the air inside of the vehicle. This
information is used to maintain the selected
temperature by initiating needed adjustments to the
temperature, the fan speed, and the air delivery
system. The system may also supply cooler air to
the side of the vehicle facing the sun. The
recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located in
the center of the instrument panel, near the
windshield, or the system will not work properly.

10. Install a new passenger compartment air lter.
SeeNormal Maintenance Replacement Parts
on page 471for the type of lter to use.
Make sure it slides under the compartment
retainers.
11. Reverse Steps 1 through 8.
For best climate control performance,
re-installation of a clean air lter is required.
Warning Lights, Gages,
and Indicators
This part describes the warning lights and gages
that may be on the vehicle. The pictures will
help you locate them.
Warning lights and gages can signal that something
is wrong before it becomes serious enough to
cause an expensive repair or replacement. Paying
attention to the warning lights and gages could also
save you or others from injury.Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. As
you will see in the details on the next few pages,
some warning lights come on briey when you
start the engine just to let you know they are
working. If you are familiar with this section, you
should not be alarmed when this happens.
Gages can indicate when there may be or is a
problem with one of your vehicle’s functions. Often
gages and warning lights work together to let
you know when there is a problem with your
vehicle.
When one of the warning lights comes on and
stays on when you are driving, or when one of the
gages shows there may be a problem, check
the section that tells you what to do about
it. Please follow this manual’s advice. Waiting to
do repairs can be costly – and even dangerous. So
please get to know the warning lights and gages.
They are a big help.

If No Steam Is Coming From Your
Engine
If you get an engine overheat warning, but see
or hear no steam, the problem may not be
too serious. Sometimes the engine can get a
little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign of
steam, try this for a minute or so:
1. In heavy traffic, let the engine idle in
NEUTRAL (N) while stopped. If it is safe to
do so, pull off the road, shift to PARK (P)
or NEUTRAL (N) and let the engine idle.
2. Set the climate controls to the highest heat
setting and fan speed and open the windows
as necessary.If you no longer have the overheat warning,
you can drive. Just to be safe, drive slower for
about 10 minutes. If the warning does not
come back on, you can drive normally.
If the warning continues and you have not
stopped, pull over, stop, and park your vehicle
right away.
If there is still no sign of steam, you can idle the
engine for three minutes while you are parked.
If you still have the warning, turn off the engine
and get everyone out of the vehicle until it
cools down. Also, see “Overheated Engine
Protection Operating Mode” later in this section.
You may decide not to lift the hood but to get
service help right away.
