Cabin air filter
[A] : Outside air, [B] : Recirculated air
[C] : Climate control air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core The cabin air filter is installed behind
the glove box. It filters the dust or other
pollutants that enter the vehiclethrough the heating and air condition-ing system.
Have the The cabin air filter replaced
by an authorized HYUNDAI dealeraccording to the maintenance sched-
ule.If the vehicle is being driven in
severe conditions such as dusty or
rough roads and/or if transporting
pets or occupants smoke inside the
vehicle, then more frequent cabin airfilter inspections and changes arerequired.
If the air flow rate suddenly decreas-
es, the system should be checked at
an authorized HYUNDAI dealer.
Checking the amount of air con-
ditioner refrigerant and com-
pressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
reduces the performance of the airconditioning system.
Therefore, if abnormal operation is
found, we recommend that the sys-
tem be inspected by an authorized
HYUNDAI dealer.
It is important that the correct type and amount of oil and refrig-
erant is used. Otherwise, damageto the compressor and abnormal
system operation may occur. To
prevent damage, the air condition-
ing system in your vehicle should
only be serviced by trained and
certified technicians.

Driving your vehicle
The severe weather conditions of
winter quickly wear out tires and
cause other problems. To minimize
winter driving problems, you should
take the following suggestions:
Snow or Icy Conditions
You need to keep sufficient distance
between your vehicle and the vehicle
in front of you.
Apply the brakes gently. Speeding,
rapid acceleration, sudden brake
applications, and sharp turns are
potentially very hazardous practices.
During deceleration, use regenera-
tive braking to the fullest extent.
Sudden brake applications on snowy
or icy roads may cause the vehicle toskid.
To drive your vehicle in deep snow, it
may be necessary to use snow tires.
Always carry emergency equipment.
Some of the items you may want to
carry include, tow straps or chains, a
flashlight, emergency flares, sand, a
shovel, jumper cables, a window
scraper, gloves, ground cloth, cover-
alls, a blanket, etc.
Snow tires
If you mount snow tires on your vehi-
cle, make sure to use radial tires of
the same size and load range as the
original tires. Mount snow tires on all
four wheels to balance your vehicle’s
handling in all weather conditions.
The traction provided by snow tires
on dry roads may not be as high as
your vehicle's original equipment
tires. Check with the tire dealer for
maximum speed recommendations.Information
Do not install studded tires without
first checking local, country and
municipal regulations for possible
restrictions against their use.
Air cleaner filter (FCEV)
The snow may block the air cleaner
filter after driving the vehicle in heavy
snow when the ambient temperature
is below 10°C (50°F).
If a warning message "Air filter
blocked. Check filter or see user
manual" appears on LCD display
after turning off the vehicle, remove
the snow from the inside of the air
cleaner filter and turn on and off the
vehicle. If the warning message is
displayed again, the exhaust pipe
may be blocked. Then, move your
vehicle indoors and leave it inside
more than one day to defrost the
exhaust pipe.
If the warning message is displayed
again, have the vehicle checked by
an authorized HYUNDAI dealer.

Snow tires should be equivalent
in size and type to the vehicle's
standard tires. Otherwise, the
safety and handling of your
vehicle may be adversely affect-ed.

Checking the Washer Fluid
Level
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary. Plain water may be used if
washer fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.
Filter Replacement
Faulty air cleaner filter has a direct
influence on reduction of the stack
output, etc. Replace the filter accord-
ing to the maintenance schedule.
OFE078008 To prevent serious injury or
death, take the following safetyprecautions when using washerfluid:
Do not use coolant or
antifreeze in the washer fluid
reservoir.
Coolant can severely obscure
visibility when sprayed on the
windshield and may cause
loss of vehicle control result-
ing in an accident or damage
to paint and body trim.
Do not allow sparks or flame to contact the washer fluid or
the washer fluid reservoir.
Washer fluid may containalcohol and can be flamma-
ble.
Do not drink washer fluid and
avoid contact with skin.
Washer fluid is harmful tohumans and animals.
Keep washer fluid away from
children and animals.

OFE078010OFE078009Do not drive with the air clean-
er filter removed. This will
result in excessive wear.
When removing the air clean-
er 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 performing the fol-
lowing procedure, and be careful to
avoid damaging other components.
1. With the glove box open, removethe stoppers on both sides to allow
the glove box to hang freely on the
hinges. 2. Remove the support rod (1).
