amperage rating.Certain electrical accessories may not be compatible
with the accessory power outlet and could result
in blown vehicle or adapter fuses. If you experience a
problem see your dealer for additional information
on accessory power outlets.

vehicle may damage it or keep other components
from working as they should. The repairs would
not be covered by your warranty. Check with your

the proper installation instructions included with
the equipment.

Power Outlet 115 Volt Alternating
Current
Your vehicle may have a power outlet that can be
used to plug in auxiliary electrical equipment with a
maximum limit of 150 watts. If you try to use equipment
that requires more than the limit, a protection circuit
will cut the power supply. To reset the outlet, unplug
the item and plug it back in or turn the ignition key
to OFF or ACC and then back on. The power will
automatically restart when equipment that operates
within the limit is plugged in.The power outlet is
located behind the
third row seats on the
passenger’s side
rear quarter trim panel.
The power outlet is not designed for the following
electrical equipment and they may not work properly:
Equipment with high initial peak wattage:
compressor-driven refrigerators and electric
power tools.
Other equipment requiring an extremely stable
power supply: microcomputer-controlled electric
blankets, touch sensor lamps, etc.

Climate Controls
Dual Climate Control System
Your vehicle may have a dual climate control system.
With this system you can control the heating, cooling
and ventilation for your vehicle.
Operation
Turn the right knob clockwise or counterclockwise to
direct the airow inside of your vehicle.
To change the current mode, select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs half of the air to the
instrument panel outlets, then directs the remaining
air to the oor outlets. Cooler air is directed to the upper
outlets and warmer air to the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets. Use this mode to send air to the rear of
the vehicle. Keep the area under the front seats free of
objects that could obstruct airow to the rear of the
vehicle.
The right knob can also be used to select defog or
defrost mode. For more information, see “Defogging
and Defrosting” later in this section.

Outside Air:This mode will be automatically selected
when your vehicle is in any mode except maximum
air conditioning.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan
speed. Turn the knob to 0 to turn off the fan. The fan

indicator light in the button will come on to let you
know that air conditioning is activated.
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.
#MAX (Maximum Air Conditioning):Turn the
right knob to this position for maximum air conditioning.
This will select air conditioning and recirculation for
maximum cooling of your vehicle.

coming in the vehicle. It can be used to prevent outside
air and odors from entering your vehicle or help heat
or cool the air inside your vehicle more quickly.
This mode will automatically be selected when you
select maximum air conditioning.

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 control 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.Turn the right knob to select the defog or defrost 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.
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 turn 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.
