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.
• After sufficient cooling has been
achieved, switch back from
recirculation mode to fresh mode.
• To help reduce moisture inside of
the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system with the windows
and sunroof closed.
• During air conditioning system
operation, 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
system, you may notice clear water
dripping (or even puddling) on the
ground under the passenger side of
the vehicle. This is a normal system
operation characteristic.
• If you operate the air conditioner
excessively, the difference between
the temperature of the outside air and
that of the windshield could cause the
outer surface of the windshield to fog
up, causing loss of visibility. In this
case, set the mode selection button to
the
position and set the fan speed
control knob to the lowest speed
setting.

Climate control air filter
OIK047401LOIK047401L
[A] : Outside air, [B] : Recirculated air
[C] : Climate control air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
This filter is installed behind the glove
box. It filters the dust or other pollutants
that enter the vehicle through the
heating and air conditioning system.
We recommend that the climate control
air filter be replaced by an authorized
HYUNDAI dealer according to the
maintenance schedule. If the vehicle is
being driven in severe conditions such
as dusty or rough roads, more frequent
climate control filter inspections and
changes are required.
If the air flow rate suddenly decreases,
we recommend the system be checked
at an authorized HYUNDAI dealer.
i Information
• Replace the filter according to the
Maintenance Schedule.
• If the car is being driven in severe
conditions such as dusty, rough roads,
more frequent climate control air filter
inspections and changes are required.
• When the air flow rate suddenly
decreases, we recommend that the
system be checked by an authorized
HYUNDAI dealer.

NOTICE
• The refrigerant system should only
be serviced by trained and certified
technicians to insure proper and safe
operation.
• The refrigerant system should be
serviced in a well-ventilated place.
• The air conditioning evaporator
(cooling coil) shall never be repaired
or replaced with one removed from
a used or salvaged vehicle and new
replacement MAC evaporators shall
be certified (and labeled) as meeting
SAE Standard J2842.
i Information
• When using the air conditioning system,
monitor the temperature gauge closely
while driving up hills or in heavy traffic
when outside temperatures are high.
Air conditioning system operation may
cause engine overheating. Continue
to use the blower fan but turn the
air conditioning system off if the
temperature gauge indicates 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 used with
the windows closed.

Maintenance
WARNING
• Inspect your tires frequently for
proper inflation as well as wear and
damage. Always use a tire pressure
gauge.
• Tires with too much or too little
pressure wear unevenly causing poor
handling, loss of vehicle control,
and sudden tire failure leading to
accidents, injuries, and even death.
The recommended cold tire pressure
for your vehicle can be found in this
manual and on the tire label located
on the driver’s side center pillar.
• Worn tires can cause accidents.
Replace tires that are worn, show
uneven wear, or are damaged.
• Remember to check the pressure
of your spare tire. HYUNDAI
recommends that you check the
spare every time you check the
pressure of the other tires on your
vehicle.
Tire rotation
To equalize tread wear, it is
recommended that the tires be rotated
every 10,000 km (6,200 miles) or sooner
if irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear
is usually caused by incorrect tire
pressure, improper wheel alignment,
out-of-balance wheels, severe braking
or severe cornering. Look for bumps
or bulges in the tread or side of tire.
Replace the tire if you find either of
these conditions. Replace the tire if
fabric or cord is visible. After rotation,
be sure to bring the front and rear tire
pressures to specification and check lug
nut tightness.
Refer to “Tire and wheels” in chapter 2.

Maintenance
NOTICE
Because the sidewall of the low aspect
ratio tire is shorter than the normal, the
wheel and tire of the low aspect ratio
tire is easier to be damaged. So, follow
the instructions below.
- When driving on a rough road or
off road, drive cautiously because
tires and wheels may be damaged.
And after driving, inspect tires and
wheels.
- When passing over a pothole, speed
bump, manhole, or curb stone, drive
slowly so that the tires and wheels
are not damaged.
- If the tire is impacted, we
recommend that you inspect the tire
condition or contact an authorized
HYUNDAI dealer.
- To prevent damage to the tire,
inspect the tire condition and
pressure every 3,000km.
NOTICE
• It is not easy to recognize the tire
damage with your own eyes. But
if there is the slightest hint of tire
damage, even though you cannot see
the tire damage with your own eyes,
have the tire checked or replaced
because the tire damage may cause
air leakage from the tire.
• If the tire is damaged by driving
on a rough road, off road, pothole,
manhole, or curb stone, it will not be
covered by the warranty.
• You can find out the tire information
on the tire sidewall.
