WARNING
∙ The air conditioner cooling function op- erates only when the engine is running.
∙ Do not leave children or adults who would normally require the assistance of
others alone in your vehicle. Pets should
also not be left alone. They could acciden-
tally injure themselves 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 interior
air to become stale and the windows 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 com-
partment through the vents.
∙ When parking, set the heater and air
conditioner controls to turn off air recir-
culation to allow fresh air into the pas-
senger compartment. This should help
reduce odors inside the vehicle
AUTOMATIC OPERATION
Press the AUTO button to set the automatic
control mode that keeps the air distribution,
temperature and the fan speed automati-
cally.
Cooling and/or dehumidified
heating (AUTO)
This mode may be used all year round as the
system automatically works to keep a con-
stant temperature. Air flow distribution, air
intake control, and fan speed are also con-
trolled automatically. 1. Press the
CLIMATE button on the
lower display menu. The CLIMATE
screen will display on the lower display.
2. Press the AUTO button on. (The indica- tor on the button will illuminate and
AUTO will be displayed on the CLIMATE
screen.)
3. Press the
temperature con-
trol buttons on the driver’s side to set the
desired temperature.
∙ 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 indi-
cate a malfunction.
Dehumidified defrosting or
defogging
1. Press thefront defroster button
on. (The indicator light on the button will
come on.) 2. Operate the
temperature
control buttons to set the desired tem-
perature.
∙ To quickly remove ice from the outside of the windows, use the
fan speed
control button or the “
” key to set
the fan speed to maximum.
∙ As soon as possible after the windshield is clean, press the AUTO button to return
to the automatic mode.
∙ When the
front defroster button is
pressed, the air conditioner will auto-
matically be turned on at outside tem-
peratures approximately 32°F (0°C) to
defog the windshield. The air recirculate
mode automatically turns off, allowing
outside air to be drawn into the passen-
ger compartment to further improve the
defogging performance.

∙ Snow can trap dangerous exhaust gasesunder 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 withan ungrounded electrical system 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 en-
gine. Damage to the cord could result in
an electrical shock and can cause serious
injury. ∙ Use a heavy-duty 3-wire, 3-pronged ex-
tension cord rated for at least 10 A. Plug
the extension cord into a Ground Fault
Interrupt (GFI) protected, grounded
110-VAC outlet. Failure to use the
proper extension cord or a grounded out-
let can result in a fire or electrical shock
and cause serious personal injury.
To use the engine block heater: 1. Turn the engine off.
2. Open the hood and unwrap the engine block 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 least2-4hours, 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.

WARNING
Always follow the instructions below. Fail-
ure to do so could result in damage to the
charging system and cause personal injury.1. If the booster battery is in another ve- hicle, position the 2 vehicles to bring their
batteries near each other.
Do not allow the two vehicles to touch.
2. Apply the parking brake. Engage the P (Park) position. Switch off all unneces-
sary electrical systems (lights, heater, air
conditioner, etc.). 3. Turn the ignition switch to the OFF po-
sition.
4. Connect the jumper cables in the se- quence illustrated (
A,B,C,D).
CAUTION
∙ Always connect positive () to positive() and negative () to body ground (for
example, strut mounting bolt, engine lift
bracket, etc.) — not to the battery.
∙ Make sure the jumper cables do not touch moving parts in the engine compartment
and that the cable clamps do not contact
any other metal. 5. Start the engine of the booster vehicle
and let it run for a few minutes.
6. Keep the engine speed of the booster vehicle at about 2,000 rpm and start the
engine of the vehicle being jump started.
CAUTION
Do not keep the starter motor engaged for
more than 10 seconds. If the engine does
not start right away, place the ignition
switch in the OFF position and wait 3 to
4 seconds before trying again.
7. After starting the engine, carefully dis- connect the negative cable and then the
positive cable.

CAUTION
∙ Continuously Variable Transmission(CVT) models cannot be push-started or
tow-started. Attempting to do so may
cause transmission damage.
∙ Do not push start this vehicle. The three- way catalyst may be damaged.
WARNING
∙ Do not continue to drive if your vehicleoverheats. Doing so could cause engine
damage or a vehicle fire.
∙ To avoid the danger of being scalded, never remove the coolant reservoir cap
while the engine is still hot. When the
coolant reservoir cap is removed, pres-
surized hot water will spurt out, possibly
causing serious injury.
∙ Do not open the hood if steam is coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading),
or if you feel a lack of engine power, detect
abnormal noise, etc. take the following steps. 1. Move the vehicle safely off the road, apply the parking brake and engage the
P (Park) position.
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed. 3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the ra-
diator before opening the hood. (If
steam or coolant is escaping, turn off the
engine.) Do not open the hood further
until no steam or coolant can be seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the engine,
stand clear to prevent getting burned.
5. Visually check drive belts for damage or looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leak-
ing, the water pump belt is missing or
loose, or the cooling fan does not run,
stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling fan
can start at any time.
