Auto Defogging System
(Only for Automatic Climate
Control System, if equipped)
Auto defogging reduces the possibil-
ity of fogging up the inside of the
windshield by automatically sensing
the moisture on inside the wind-
shield.
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
temperature is below 50 °F (-10 °C).When the Auto Defogging
System operates, the indi-
cator will illuminate.
If high levels of moisture are sensed in
the vehicle, the Auto Defogging System
will operate in the following order:
Step 1: Outside air position
Step 2:Operating the air conditioning
Step 3: Blowing air toward the wind-
shield
Step 4: Increasing air flow toward the
windshield
If the air conditioning is off or recircu-
lated air position is manually selected
while Auto Defogging System is ON,
the Auto Defogging System Indicator
will blink 3 times to signal that the
manual operation has been canceled.
To cancel or reset the
Auto Defogging System
Press the front windshield defroster
button for 3 seconds when the ignition
switch is in the ON position. When the
Auto Defogging System is canceled,
the ADS OFF symbol will blink 3 times
and ADS OFF will be displayed on the
climate control information screen.When the Auto Defogging System is
reset, the ADS OFF symbol will blink
6 times without a signal.
Information
• When the air conditioning is turned
on by Auto defogging system, if you
try to turn off the air conditioning, the
indicator will blink 3 times and the air
conditioning will not be turned off.
• For efficiency, do not select recircu-
lated air position while the Auto
defogging system is operating.
• When Auto defogging mode is
selected, fan speed, temperature and
intake mode which is adjusted man-
ually are canceled for better defog-
ging result.
Do not remove the sensor cover
located on the upper end of the
windshield glass.
Damage to system parts could
occur and may not be covered by
your vehicle warranty.

Rear Window Defroster
To prevent damage to the conduc-
tors bonded to the inside surface
of the rear window, never use
sharp instruments or window
cleaners containing abrasives to
clean the window.
If you want to defrost and defog
the front windshield, refer to the
"Windshield Defrosting and
Defogging" section in this chapter.
The defroster heats the window to
remove frost, fog and thin ice from
the interior and exterior of the rear
window, while the engine is running. To activate the rear window
defroster, press the rear window
defroster button located in the center
facia switch panel. The indicator on
the rear window defroster button illu-
minates when the defroster is ON.
To turn off the defroster, press the
rear window defroster button again.

• If there is heavy accumulation of
snow on the rear window, brush it off
before operating the rear defroster.
• The rear window defroster automat-
ically turns off after approximately
20 minutes or when the ignition
switch is in the LOCK/OFF position.
Side view mirror defroster
If your vehicle is equipped with the
side view mirror defrosters, they will
operate at the same time you turn on
the rear window defroster.

Maintenance
Information
If the vehicle is operated in extremely
dusty or sandy areas, replace the ele-
ment more often than the usual rec-
ommended intervals (refer to
"Maintenance Under Severe Usage
Conditions" in this chapter).
Do not drive with the air cleaner
filter removed. This will result in
excessive engine wear.
When removing the air cleaner
filter, be careful that dust or dirt
does not enter the air intake, or
damage may result.
Use HYUNDAI genuine parts.
Use of non-genuine parts could
damage the air flow sensor.
Filter Inspection
The climate control air filter should
be replaced according to the
Maintenance Schedule. If the vehicle
is operated in severely air-polluted
cities or on dusty rough roads for a
long period, it should be inspected
more frequently and replaced earlier.
When you replace the climate control
air filter, replace it performing the fol-
lowing procedure, and be careful to
avoid damaging other components.
1. With the glove box open, lower the
glove box by pushing both sides.
