WARNING
Windshield heating
Do not use the
position during
cooling operation in extremely humid
weather. The difference between the
temperature of the outside air and that
of the windshield could cause the outer
surface of the windshield to fog up,
causing loss of visibility could cause
an accident resulting in serious injury
or death. In this case, set the mode
selection to the
position and fan
speed control to a lower speed. • For maximum defrost performance,
set the temperature control to the
highest temperature setting and
the fan speed control to the highest
setting.
• If warm air to the floor is desired while
defrosting or defogging, set the mode
to the floor-defrost position.
• Before driving, clear all snow and ice
from the windshield, rear window,
outside rearview mirrors, and all side
windows.
• Clear all snow and ice from the
hood and air inlet in the cowl grill
to improve heater and defroster
efficiency and to reduce the
probability of fogging up the inside of the windshield.

Auto Defogging System
ONE1051072
Auto defogging helps reduce the
possibility of fogging up the inside of the
windshield by automatically sensing the
moisture on inside the windshield.
Information
The auto defogging system may not
operate normally, when the outside
temperature is below 14 °F (-10 °C).
When the Auto Defogging
System operates, the indicator
will illuminate.
If a high amount of humidity is detected
in the vehicle, the Auto Defogging
System will be enabled. The following
steps will be performed automatically:
Step 1) Air conditioning will turn ON.
Step 2) Air intake control will change to Fresh mode.
Step 3) Mode will change to defrost to direct airflow to the windshield.
Step 4) Fan speed will be set to MAX.
If the air conditioning is off or
recirculation mode is manually selected
while Auto Defogging System is ON, the
Auto Defogging System will be canceled.

Jump starting procedure
Information
When you jump start your vehicle,
use the jumper terminal in the motor compartment.
1. Position the vehicles close enough that the jumper cables will reach, but
do not allow the vehicle body parts to
contact.
2. Avoid fans or any moving parts in the motor compartment at all times, even
when the vehicles are turned off.
3. Turn off all electrical devices such as radios, lights, air conditioning, etc.
Put the vehicles in P (Park) and set the
parking brake. Turn both vehicles OFF.
4. Open the hood.
5. Remove the battery cover located inside of the front trunk.
6. Remove the motor compartment fuse box cover.
CAUTION
Before jump starting, make sure to
correctly identify the positive (+) and
negative (-) terminals to avoid reverse
polarity connections.
ONE1081003
7. Connect the jumper cables in
the exact sequence shown in the
illustration. First connect one jumper
cable to the red, positive (+) jumper
terminal of your vehicle (1).
8. Connect the other end of the jumper cable to the red, positive (+) battery/
jumper terminal of the assisting
vehicle (2).
9. Connect the second jumper cable to
the black, negative (-) battery/jumper
terminal of the assisting vehicle (3).
10. Connect the other end of the second
jumper cable to the black, negative (-)
chassis ground of your vehicle (4).
Do not allow the jumper cables to
contact anything except the correct
battery or jumper terminals or the
correct ground. Do not lean over the
battery when making connections.
WARNING
Do not connect the jumper cable to
the negative (-) jumper terminal of the
discharged battery. A spark could cause
the battery to explode and lead to a
personal injury or vehicle damage.

Maintenance

Owner Maintenance Schedule
When you stop for charging: • Check the coolant level in the coolant
reservoir.
• Check the windshield washer fluid
level.
• Check for low or under-inflated tires.
WARNING
Be careful when checking your coolant
level when the motor compartment is
hot. This may result in coolant being
blown out of the opening and cause
serious burns and other injuries.
While operating your vehicle: • Check for vibrations in the steering
wheel. Notice if there is any increased
steering effort or looseness in the
steering wheel, or change in its
straight-ahead position.
• Notice if your vehicle constantly turns
slightly or “pulls” to one side when
traveling on smooth, level road.
• When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
• If any slipping or changes in the
operation of your gear shift occurs,
check the shift gear fluid level.
• Check the shift gear P (Park) function.
• Check the parking brake.
• Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after use is normal). At least monthly: •
Check coolant level in the coolant
reservoir.
• Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flashers.
• Check the inflation pressures of all
tires including the spare for tires that
are worn, show uneven wear, or are damaged.
• Check for loose wheel lug nuts.
At least twice a year: (for example,
every Spring and Autumn) • Check radiator, heater and air
conditioning hoses for leaks or damage.
• Check windshield washer spray and
wiper operation. Clean wiper blades
with a clean cloth dampened with
washer fluid.
• Check headlamp alignment.
• Check the seat belts for wear and function.
At least once a year: • Clean body and door drain holes.
• Lubricate door hinges and hood hinges.
• Lubricate door and hood locks and
latches.
• Lubricate door rubber weather strips.
• Check the air conditioning system.
• Inspect and lubricate shift gear
linkage and controls.
• Clean the battery (12V) and terminals.
• Check the brake fluid level.
