Certain power accessory plugs may not be compatible
to the accessory power outlet and could result in
blown vehicle or adapter fuses. If you experience a
problem, see your dealer/retailer for additional
information on the accessory power plugs.
The accessory power outlets are powered, even when
the ignition is in LOCK/OFF. Continuing to use
power outlets while the ignition is in LOCK/OFF may
cause the vehicle’s battery to run down.
Notice:Adding any electrical equipment to the
vehicle can damage it or keep other components
from working as they should. The repairs would not
be covered by the vehicle warranty. Do not use
equipment exceeding maximum amperage rating of
20 amperes. Check with your dealer/retailer before
adding electrical equipment.
When adding electrical equipment, be sure to follow the
proper installation instructions included with the
equipment.
Notice:Improper use of the power outlet can cause
damage not covered by the 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.Ashtray(s) and Cigarette Lighter
The vehicle may have a front ashtray located near the
center of the instrument panel. Pull on the door to
open it. The ashtray may have a cigarette lighter.
Notice:If papers, pins, or other ammable items
are put in the ashtray, hot cigarettes or other
smoking materials could ignite them and possibly
damage the vehicle. Never put ammable items
in the ashtray.
To remove the ashtray, open the door and pull the
ashtray bin toward you. To replace the ashtray, insert
the ashtray bin inside the ashtray door and press down
until it engages. To use the cigarette lighter, push it
in all the way, and let go. When it is ready for use, the
lighter pops back out.
Notice:Holding a cigarette lighter in while it is
heating does not let the lighter back away from the
heating element when it is hot. Damage from
overheating can occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating.

The recirculation mode cannot be selected in the defog
or defrost mode. When either mode is selected, the
system runs the air conditioning compressor, unless the
outside temperature is close to freezing.
Do not drive the vehicle until all the windows are clear.
:(Outside Air):Press to turn the outside air
mode on. An indicator light comes on to show that
outside air is on. In this mode outside air circulates
throughout the vehicle. The outside air mode can
be used with all modes, but it cannot be used with the
recirculation mode.
?(Recirculation):Press to turn the recirculation
mode on. An indicator light comes on to show that
recirculation is on.
This mode recirculates and helps to quickly cool the air
inside the vehicle. It can be used to help prevent
outside air and odors from entering the vehicle.
The recirculation mode cannot be used with oor, defog
or defrost modes. If recirculation is selected with one of
these modes, the indicator light ashes three times and
then turns off. While in recirculation mode the windows
may fog when the weather is cold and damp. To clear the
fog, select either the defog or defrost mode and increase
the fan speed.
The recirculation mode can be turned off by pressing the
outside air button, or by turning off the ignition.
#(Air Conditioning):Press to turn the air conditioning
system on or off. An indicator light comes on to show that
the air conditioning is on. The air conditioning can be
selected in any mode as long as the fan switch is on.
The air conditioning system removes moisture from the
air, so a small amount of water might drip under the
vehicle while idling or after turning off the engine.
This is normal.
Rear Window Defogger
For vehicles with a rear window defogger, a warming
grid is used to remove fog from the rear window.
<(Rear):Press to turn the rear window defogger on
or off. An indicator light on the button comes on to
show that the rear window defogger is on.
The rear window defogger only works when the ignition
is in ON/RUN. The rear window defogger stays on
for approximately 10 minutes after the button is pressed,
unless the ignition is turned to ACC/ACCESSORY or
LOCK/OFF. The defogger can also be turned off
by turning off the engine.
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 the vehicle warranty. Do not attach
a temporary vehicle license, tape, a decal or
anything similar to the defogger grid.
