Auto Defogging System (Only
for Automatic Climate Control
System, if equipped)
Auto defogging reduces the possibility of
fogging up the inside of the windshield by
automatically sensing the moisture of
inside the windshield.
The auto defogging system operates
when the heater or air conditioning is on.
Information
The auto defogging system may not oper-
ate normally, when the outside tempera-
ture is below 50 °F (-10 °C).When the Auto Defogging
System operates, the indica-
tor will illuminate.
If higher level 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 : Blo wing air toward the wind-
shield
Step 4 : Increasing air flow toward the windshield
If the air conditioning is off or recirculated
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 but-
ton for 3 seconds when the ignition
switch is in the ON position. When the
Auto Defogging System is canceled,
ADS OFF symbol will blink 3 times and
the ADS OFF will be displayed on the cli-
mate control information screen.
When the Auto Defogging System is
reset, 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 indica-
tor will blink 3 times and the air condi-
tioning will not be turned off.
• For efficiency, do not select recirculated air position while Auto defogging system
is operating.
• When Auto defogging mode is selected, fan speed, temperature and intake mode
which is adjusted manually are canceled
for better defogging result.
Do not remove the sensor cover locat-
ed on the upper end of the driver side
windshield glass.
Damage to system parts could occur
and may not be covered by your vehi-
cle warranty.

Information
If the vehicle is operated in extremely
dusty or sandy areas, replace the element
more often than the usual recommended
intervals (refer to "Maintenance Under
Severe Usage Conditions" in this chapter).
Do not drive with the air cleaner fil-ter 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 per-
forming the following procedure, and be
careful to avoid damaging other compo-
nents.
1. With the glove box open, remove thestoppers on both sides to allow the
glove box to hang freely on the hinges.
