WARNING
• The air conditioner cooling function
operates only when the engine is
running.
• Do not leave children or adults who
would normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
• Do not use the recirculation mode for
long periods as it may cause the inte-
rior air to become stale and the win-
dows to fog up.
Start the engine and operate the controls
to activate the air conditioner.
NOTE:
• Odors from inside and outside the ve- hicle can build up in the air conditioner
unit. Odor can enter the passenger
compartment through the vents.

• When parking, set the heater and airconditioner controls to turn off air re-
circulation to allow fresh air into the
passenger compartment. This should
help reduce odors inside the vehicle.
AUTOMATIC OPERATION
Cooling and/or dehumidified
heating (AUTO)
This mode may be used all year round as
the system automatically works to keep a
constant temperature. Air flow distribution,
air intake control, and fan speed are also
controlled automatically.
1. Press the AUTO button on.
2. Turn the temperature control dial to the lef t or right to set the desired
temperature.
• Adjust the temperature display to about 75°F (24°C) for normal operation.
• The temperature of the passenger com- partment will be maintained automati-
cally. Air flow distribution, air intake con-
trol and fan speed are also controlled
automatically. • A visible mist may be seen coming from
the vents in hot, humid conditions as the
air is cooled rapidly. This does not indicate
a malfunction.
3. You can individually set driver's and front passenger's side temperature using
each temperature control dial. To syn-
chronize the driver’s and front passen-
ger’s temperature settings, press the
SYNC button.
Heating (A/C OFF)
The air conditioner does not activate. When
you need to heat only, use this mode.
1. Press the AUTO button.
2. Turn the temperature control dial to set the desired temperature.
• The temperature of the passenger com- partment will be maintained automati-
cally. Air flow distribution and fan speed
are also controlled automatically.
• Do not set the temperature lower than the outside air temperature. Otherwise,
the system may not work properly.
• Not recommended if windows fog up.
Dehumidified defrosting or
defogging
1. Press thefront defroster button on.
2. Turn the temperature control dial to set the desired temperature.
• To quickly remove ice from the outside of the windows, use the

SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
• A scraper and stiff-bristled brush to re-move ice and snow from the windows
and wiper blades.
• A sturdy, flat board to be placed under the jack to give it firm support.
• A shovel to dig the vehicle out of snowdrif ts.
• Extra washer fluid to refill the windshield- washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
• Wet ice (32°F, 0°C and freezing rain),
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” un-
der these conditions. Try to avoid
driving on wet ice until the road is
salted or sanded.
• Whatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shif ting too fast, the drive wheels will
lose even more traction. •
Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry
pavement.
• Allow greater following distances on
slippery roads.
• Watch for slippery spots (glare ice).
These may appear on an otherwise
clear road in shaded areas. If a patch
of ice is seen ahead, brake before
reaching it. Try not to brake while on
the ice, and avoid any sudden steer-
ing maneuvers.
• Do not use the cruise control on slip-
pery roads.
• Snow can trap dangerous exhaust
gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.
ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist
with cold temperature starting.
The engine block heater should be used
when the outside temperature is 20°F (-7°C)
or lower.
WARNING
• Do not use your engine block heater
with an ungrounded electrical sys-
tem or a 2-pronged adapter. You can
be seriously injured by an electrical
shock if you use an ungrounded
connection.
• Disconnect and properly store the
engine block heater cord before
starting the engine. Damage to the
cord could result in an electrical
shock and can cause serious injury.
• Use a heavy-duty 3-wire, 3-pronged
extension cord rated for at least 10 A.
Plug the extension cord into a
Ground Fault Interrupt (GFI) pro-
tected, grounded 110-VAC outlet.
Failure to use the proper extension
cord or a grounded outlet can result
in a fire or electrical shock and cause
serious personal injury.
5-186Starting and driving

To use the engine block heater:
1. Turn the engine off.
2. Open the hood and unwrap the engineblock heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged extension
cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected, grounded
110-volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least 2–4 hours, de-
pending on outside temperatures, to
properly warm the engine coolant. Use
an appropriate timer to turn the engine
block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it away
from moving parts.
ACTIVE NOISE CANCELLATION
This system uses microphonesO1located
inside the vehicle to detect engine boom-
ing noise. The system then automatically
generates a noise canceling sound
through the speakers and woofer (if so
equipped) to reduce engine booming
noise.
NOTE:
To operate the active noise cancella-
tion system properly:
• Do not cover the speakers or woofer (if so equipped). • Do not cover the microphones.
• Do not change or modif y speakers in-
cluding the woofer (if so equipped) and
any audio related components such as
the amplifier.
• Do not make any modification includ- ing sound deadening or modifications
around the microphones or speakers.
ACTIVE SOUND ENHANCEMENT
Active sound enhancement enhances ex-
isting engine sounds according to the en-
gine speed and driving modes through the
speakers and woofer (if so equipped).
