When using the air conditioning
system, monitor the engine tem-
perature gauge closely while driv-
ing up hills or in heavy traffic
when outside temperatures are
high. Air conditioning system
operation when climbing a steep
grade or in high outside ambient
temperatures can cause engine
overheating. Continue to use the
fan, but turn the air conditioning
system off if the engine tempera-
ture gauge indicates engine over-
heating.
Air conditioning system operation
tips
If the vehicle has been parked in direct sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
After sufficient cooling has been achieved, switch back from recir-
culation mode to fresh mode. To help reduce moisture inside of
the windows on rainy or humid
days, decrease the humidity
inside the vehicle by operating the
air conditioning system with the
windows and sunroof closed.
Use the air conditioning system every month only for a few min-
utes to ensure maximum system
performance.
If you operate air conditioner excessively, the difference
between the temperature of the
outside air and that of the wind-
shield could cause the outer sur-
face of the windshield to fog up,
causing loss of visibility. In this
case, set the mode selection knob
or button to the position and
fan speed control to the lower
speed.
System Maintenance
Cabin air filter

The cabin air filter is installed behind
the glove box. It filters the dust or
other pollutants that enter the vehicle
through the heating and air condi-
tioning system.

Convenient features of your vehicle For maximum defrost perform-ance, set the temperature control
knob to the highest temperature
setting (rotated all the way to the
right) 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 posi-
tion.
Before driving, clear all snow and ice from the windshield, rear win-
dow, side view 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 effi-
ciency and to reduce the probabili-
ty of fogging up the inside of the
windshield.
If the engine temperature is still
cold after starting, then a brief
engine warm up period may be
required for the vented air flow to
become warm or hot.
Manual Climate Control System
To defog inside windshield
1. Select any fan speed except "0" position.
2. Select the desired temperature.
3. Select the or position.
4. Fresh mode will be selected auto- matically. Additionally, the air condi-
tioning will automatically operate if
the mode is selected to the
position.
Check to make sure the A/C is ON. If
the A/C ON LED is not illuminated,
press the A/C button once to turn the
air conditioner ON.

Windshield heating
Do not use the or posi-
tion during cooling operation in
extremely humid weather. The
difference between the temper-
ature of the outside air and that
of the windshield could cause
the outer surface of the wind-
shield to fog up, causing loss of
visibility could cause an acci-
dent resulting in serious injury
or death. In this case, set the
mode selection knob or button
to the position and fan
speed control knob or button to
a lower speed.

Control System) (if equipped)
Auto defogging helps reduce the pos-
sibility of fogging up the inside of the
windshield by automatically sensing
the moisture on inside the windshield.
The auto defogging system operates
when the heater or air conditioning is
on.
Information
The auto defogging system may not
operate normally, when the outside

The ISG system helps reduce fuel
consumption and exhaust gas emis-
sions by automatically shutting down
the engine, when the vehicle is at a
standstill (i.e. red stop light, stop
sign, and traffic jam).
The engine is automatically started
upon satisfying the starting condi-
tions.
The ISG system is always active,
when the engine is running.
Information
When the engine is automatically
started by the ISG system, some warn-
ing lights (i.e. ABS, ESC, ESC OFF,
EPS, and parking brake warning
light) may illuminate for a few sec-
onds due to the low battery voltage.
However, it does not indicate a mal-
function with the ISG system.
To Activate the ISG System
Prerequisite for activation

lowing situations.
The driver's seatbelt is fastened
The driver's door and hood areclosed
The brake vacuum pressure is adequate
The battery sensor is activated and the battery is sufficiently
charged
Outside temperature is not too low or too high
The vehicle is driven over a con- stant speed and stops
The climate control system satis- fies the conditions
The vehicle is sufficiently warmed up
The incline is gradual
The steering wheel is turned less than 180 degrees and then the

tem are unsatisfied.
In this case, the ISG
OFF button indicator illuminates,
and the auto stop indicator ( )
illuminates in yellow on the instru-
