Battery saver function
The purpose of this feature is to pre-
vent the battery from being dis-
charged. The system automatically
turns off the parking lamp when the

will turn off automatically if the driver
parks on the side of road at night.
If necessary, to keep the lamps on
when the engine is turned off, perform
the following:
1) Open the driver-side door.
2) Turn the parking lamps OFF andON again using the light switch on
the steering column.
Headlamp delay function (if equipped)
If engine Start/Stop button is in the
ACC or OFF position with the head-
lamps ON, the headlamps (and/or
parking lamps) remain on for about 5
minutes. However, if the driver’s door
is opened and closed, the headlamps
are turned off after 15 seconds.
However, with the engine off if the dri-
ver’s door is opened and closed, the
headlamps (and/or parking lamps)
are turned off after 15 seconds.
The headlamps (and/or parking
lamps) can be turned off by pressing
the lock button on the smart key
twice or turning the light switch to the
OFF or AUTO position. However, if
you turn the light switch to the AUTO
position when it is dark outside, the

Headlamp Delay function from the
User Settings Mode (Light) on the
LCD display.
For more information, refer to the
"LCD Display" section in this
chapter. If the driver gets out of the vehicle
through other doors (except dri-
ver’s door), the battery saver func-
tion does not operate and the

turn off automatically. Therefore, It
causes the battery to be dis-

Operation Tips
To keep dust or unpleasant fumesfrom entering the vehicle through
the ventilation system, temporarily
set the air intake control to the
recirculated air position. Be sure to
return the control to the fresh air
position when the irritation has
passed to keep fresh air in the
vehicle. This will help keep the driv-
er alert and comfortable.
Air for the heating/cooling system is drawn in through the grilles just
ahead of the windshield. Care
should be taken that these are not
blocked by leaves, snow, ice or
other obstructions.
To prevent interior fog on the wind- shield, set the air intake control to
the fresh air position and fan speed
to the desired position, turn on the
air conditioning system, and adjust
the temperature control to desired
temperature.

Convenient features of your vehicle
Operating the air conditioning sys- tem in the recirculated air position
provides maximum cooling, how-
ever, continual operation in this
mode may cause the air inside the
vehicle to become stale.
During cooling operation, you may occasionally notice a misty air flow
because of rapid cooling and
humid air intake. This is a normal
system operation characteristic.
System maintenance
Climate control air filter
The climate control air filter installed
behind the glove box filters the dust
or other pollutants that come into the
vehicle from the outside through the
heating and air conditioning system.
If dust or other pollutants accumulate
in the filter over a period of time, the
air flow from the air vents may
decrease, resulting in moisture accu-
mulation on the inside of the wind-
shield even when the outside (fresh)
air position is selected. If this hap-
pens, we recommend that the cli-
mate control air filter be replaced by
an authorized HYUNDAI dealer.
Information
• Replace the filter according to theMaintenance Schedule.
If the car is being driven in severe
conditions such as dusty, rough
roads, more frequent climate con-
trol air filter inspections and
changes are required.
• When the air flow rate suddenly decreases, we recommend that the
system be checked by an authorized
HYUNDAI dealer.

For maximum windshield defrost-
ing, set the temperature control
knob to the highest temperature
setting and the fan control knob to
the highest fan speed. Select the
front defrost button on the climate
control display. After the engine
warm-up period, warm air will be
directed to the front windshield.
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 win-
dow, outside rear 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 probability
of fogging up the inside of the wind-
shield.
To reduce tendency of the glass fogging and also to improve visibil-
ity, keep the interior surface of the
windshield clean by wiping it with a
clean cloth and glass cleaner. 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.NOTICE
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.
