Features of your vehicle
Air quality control system
(if equipped)
The air inflow from outside the vehicle
can be automatically controlled. Press
the button to activate the air quality con-
trol system.
When using AQS mode, AQS(Air Quality
control System) automatically senses
outdoor air pollutants and minimizes
them from entering the vehicle, however,
unpleasant or foul odors that might be
present may still be noticeable within the
vehicle.Exhaust gas cutoff mode :
Air enters the vehicle from the outside.
If exhaust gas enters the vehicle from the
outside, the exhaust gas cutoff mode is
automatically converted from the outside
air position to the recirculated air position
to prevent exhaust gas from entering the
vehicle.
✽NOTICE
It should be noted that prolonged oper-
ation of the heating system in recircula-
tion mode will give rise to misting of the
windshield and side windows and the air
within the passenger compartment will
become stale. In addition, prolonged use
of the air conditioning with the recircu-
lation mode selected may result in the
air within the passenger compartment
becoming excessively dry.

Air conditioning
HYUNDAI Air Conditioning Systems are
filled with environmentally friendly
R-134a refrigerant.
1. Start the engine. Press the air condi-
tioning button.
2. Set the mode to the position.
3. Set the air intake control to the outside
air or recirculated air position.
4. Adjust the fan speed control and tem-
perature control to maintain maximum
comfort.
✽NOTICE
• When using the air conditioning sys-
tem, monitor the temperature gauge
closely while driving up hills or in
heavy traffic when outside tempera-
tures are high. Air conditioning sys-
tem operation may cause engine over-
heating. Continue to use the blower
fan but turn the air conditioning sys-
tem off if the temperature gauge indi-
cates engine overheating.
• When opening the windows in humid
weather air conditioning may create
water droplets inside the vehicle.
Since excessive water droplets may
cause damage to electrical equipment,
air conditioning should only be run
with the windows closed.
Air conditioning system operation tips
• If the vehicle has been parked in direct
sunlight during hot weather, open the
windows for a short time to let the hot
air inside the vehicle escape.
• To help reduce moisture inside of the
windows on rainy or humid days,
decrease the humidity inside the vehi-
cle by operating the air conditioning
system.
• During air conditioning system opera-
tion, you may occasionally notice a
slight change in engine speed as the
air conditioning compressor cycles.
This is a normal system operation
characteristic.
• Use the air conditioning system every
month only for a few minutes to ensure
maximum system performance.• When using the air conditioning sys-
tem, you may notice clear water drip-
ping (or even puddling) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic.
• Operating the air conditioning system
in the recirculated air position provides
maximum cooling, however, 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 opera-
tion characteristics.

Features of your vehicle
Climate control air filter
(if equipped)
The 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 every 15,000 km
(10,000 miles) or once a year.
If the car is being driven in severe
conditions such as dusty or rough
roads, more frequent air conditioner
filter 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 lubricant
When the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a negative
impact on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized HYUNDAI dealer.
✽NOTICE
It 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.

Do not use the or position
during cooling operation in
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

Driving your vehicle
• Don't coast down hills with the vehicle
out of gear. This is extremely haz-
ardous. Keep the car in gear at all
times, use the brakes to slow down,
then shift to a lower gear so that
engine braking will help you maintain a
safe speed.
• 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 transmission, don't let your
car creep forward. To avoid creeping
forward, keep your foot firmly on the
brake pedal when the car is stopped.
• Be caution when parking on a hill.
Firmly engage the parking brake and
place the shift lever in P. 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 shift lever
in P and block the rear wheels so the
car cannot roll. Then release the park-
ing brake.
• Do not hold the vehicle on the upgrade
with the accelerator pedal. This can
cause the transmission to overheat.
Always use the brake pedal or parking
brake.

Hazardous driving conditions
When hazardous driving conditions are
encountered such as water, snow, ice,
mud, sand, or similar hazards, follow
these suggestions:
• Drive cautiously and allow extra dis-
tance for braking.
• Avoid sudden movements in braking or
steering.• If stalled in snow, mud, or sand, use
second gear. Accelerate slowly to
avoid spinning the drive wheels.
• Use sand, rock salt, tire chains, or
other non-slip material under the drive
wheels to provide traction when stalled
in ice, snow, or mud.
Rocking the vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first turn
the steering wheel right and left to clear
the area around your drive wheels. Then,
shift back and forth between R (Reverse)
and any forward gear in vehicles
equipped with an automatic transmis-
sion. Do not race the engine, and spin
the wheels as little as possible. If you are
still stuck after a few tries, have the vehi-
cle pulled out by a tow vehicle to avoid
engine overheating and possible dam-
age to the transmission.
SPECIAL DRIVING CONDITIONS
OVI059043
WARNING - ABS
Do not pump the brake pedal on a
vehicle equipped with ABS.
WARNING - Downshifting
Downshifting with an automatic
transmission, while driving on slip-
pery surfaces can cause an acci-
dent. The sudden change in tire
speed could cause the tires to skid.
Be careful when downshifting on
slippery surfaces.CAUTION
Prolonged rocking may cause
engine over-heating, transmission
damage or failure, and tire damage.
