4Automatic heating and air condi-
tioningThe automatic climate control system is
controlled by simply setting the desired
temperature.
The Full Automatic Temperature Control
(FATC) system automatically controls the
heating and cooling system as follows;
1. Push the AUTO button. The modes,
fan speeds, air intake and air-condi-
tioning will be controlled automatically
by the temperature setting. 2. Turn the temperature control knob to
set the desired temperature.
If the temperature is set to the lowest
setting, the air conditioning system will
operate continuously.
3. To turn the automatic operation off, press any button except the tempera-
ture control knob. If you press the
mode selection button, air conditioning
button, defrost button or air intake con-
trol button, or the fan speed button, the
selected function will be controlled
manually while other functions operate
automatically.
For your convenience and to improve the
effectiveness of the climate control, use
the AUTO button and set the temperature
to 73°F (23°C).

What to do in an emergency10
6Changing a tire with TPMS
If you have a flat tire, the Low Tire
Pressure will come on. Have the flat
tire repaired by an authorized
HYUNDAI dealer as soon as possi-
ble or replace the flat tire with the
spare tire.
Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specific wheels. It is rec-
ommended that you always have
your tires serviced by an authorized
HYUNDAI dealer. Even if you replace the low pressure
tire with the spare tire, the Low Tire
Pressure telltale/TPMS malfunction
indicator will remain on until the low
pressure tire is repaired and placed
on the vehicle.
After you replace the low pressure
tire with the spare tire, the TPMS
malfunction indicator may illuminate
after a few minutes because the
TPMS sensor mounted on the spare
wheel is not initiated.
Once the low pressure tire is reinflat-
ed to the recommended pressure
and installed on the vehicle or the
TPMS sensor mounted on the
replaced spare wheel is initiated by
an authorized HYUNDAI dealer, the
TPMS malfunction indicator and the
low tire pressure telltale will extin-
guish within a few minutes of driving.
If the indicator is not extinguished
after a few minutes of driving, please
visit an authorized HYUNDAI dealer.
CAUTION
If original mounted tire is
replaced with the spare tire, theTPMS sensor on the replacedspare wheel should be initiatedand the TPMS sensor on theoriginal mounted wheel shouldbe deactivated. If the TPMS sen-sor on the original mountedwheel located in the spare tirecarrier still activates, the tirepressure monitoring systemmay not operate properly. Havethe tire with TPMS serviced orreplaced by an authorizedHYUNDAI dealer.
CAUTION
NEVER use a puncture-repair-ing agent to repair and/or inflatea low pressure tire. The tiresealant can damage the tirepressure sensor. If used, youwill have to replace the tire pres-sure sensor.

7Replace the filter according to the
Maintenance Schedule.If the vehicle is operated in extremely
dusty or sandy areas, replace the ele-ment more often than the usual recom-mended intervals. (Refer to “Maintenance under severe usage condi-tions” in this section.)
Filter inspectionThe 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.
Filter replacement1. Open the glove box and remove the support strap (1).
CAUTION
 Do not drive with the air cleaner removed; this will result in exces-sive engine wear.
 When removing the air cleaner fil- ter, be careful that dust or dirtdoes not enter the air intake, ordamage may result.
 Use a HYUNDAI genuine part. Use of non-genuine parts could dam-age the air flow sensor.
