4Climate control air filterThe climate control air filter installed
behind the glove box filters the dust or
other pollutants that come into the vehi-
cle 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 accumulation on the inside of
the windshield even when the outside
(fresh) air position is selected. If this hap-
pens, have the climate control air filter
replaced by an authorized HYUNDAI
dealer.
✽ ✽
NOTICE• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in severe
conditions such as dusty, rough roads,
more frequent climate control air fil-
ter inspections and changes are
required.
• When the air flow rate suddenly decreases, the system should be
checked at an authorized HYUNDAI
dealer.
Checking the amount of air con-
ditioner refrigerant and compres-
sor lubricantWhen the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a negative
influence on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized HYUNDAI dealer.✽ ✽ NOTICEIt is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor
and abnormal system operation may
occur.

Recirculated air positionWith the recirculated airposition selected, air from
the passenger compart-
ment will be drawn through
the heating system and
heated or cooled according
to the function selected.
Outside (fresh) air position With the outside (fresh) air
position selected, air enters
the vehicle from outside and
is heated or cooled accord-
ing to the function selected.✽ ✽NOTICEProlonged operation of the heater in the
recirculated air position (without air
conditioning selected) may cause fog-
ging of the windshield and side windows
and the air within the passenger com-
partment may become stale.
In addition, prolonged use of the air con-
ditioning with the recirculated air posi-
tion selected will result in excessively dry
air in the passenger compartment.
Fan speed controlThe fan speed can be set to the desired
speed by pushing the fan speed control
button.
To change the fan speed, press the right
of the button ( ) for higher speed, or
press the left of the button ( ) for lower
speed. To turn the fan speed control off,
press the OFF button.
WARNING
Continued use of the climate con-
trol system operation in the recir-
culated air position may allow
humidity to increase inside the
vehicle which may fog the glass
and obscure visibility.
Do not sleep in a vehicle with the air conditioning or heating system
on. It may cause serious harm or
death due to a drop in the oxygen
level and/or body temperature.
Continued use of the climate con- trol system operation in the recir-
culated air position can cause
drowsiness or sleepiness, and loss
of vehicle control. Set the air intake
control to the outside (fresh) air
position as much as possible while
driving.

to the floor-defrost position.
Before driving, clear all snow and ice from the windshield, rear window, out-
side rear view mirrors, and all side win-
dows.
Clear all snow and ice from the hood and air inlet in the cowl grill to improve
heater and defroster efficiency and to
reduce the probability of fogging up the
inside of the windshield.

extremely humid weather. The dif-
ference 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 knob or button to
a lower speed.

Driving your vehicle30
5 Don't "ride" the brake pedal. Resting
your foot on the brake pedal while driv-
ing can be dangerous because it can
result in the brakes overheating and
losing their effectiveness. It also
increases the wear of the brake com-
ponents.
If a tire goes flat while you are driving, apply the brakes gently and keep the
car pointed straight ahead while you
slow down. When you are moving
slowly enough for it to be safe to do so,
pull off the road and stop in a safe
place.
If your vehicle is equipped with an automatic transaxle, don't let your vehi-
cle creep forward. To avoid creeping
forward, keep your foot firmly on the
brake pedal when the vehicle is
stopped. Use caution when parking on a hill.
Firmly engage the parking brake and
place the shift lever in P (automatic
transaxle) or in first or reverse gear
(manual transaxle). If your vehicle is
facing downhill, turn the front wheels
into the curb to help keep the vehicle
from rolling. If your vehicle is facing
uphill, turn the front wheels away from
the curb to help keep the vehicle from
rolling. If there is no curb or if it is
required by other conditions to keep
the vehicle from rolling, block the
wheels.
Under some conditions your parking brake can freeze in the engaged posi-
tion. This is most likely to happen when
there is an accumulation of snow or ice
around or near the rear brakes or if the
brakes are wet. If there is a risk that the
parking brake may freeze, apply it only
temporarily while you put the gear
selector lever in P (automatic
transaxle) or in first or reverse gear
(manual transaxle) and block the rear
wheels so the vehicle cannot roll. Then
release the parking brake. Do not hold the vehicle on the upgrade
with the accelerator pedal. This can
cause the transaxle to overheat.
Always use the brake pedal or parking
brake.
