Air conditioning
Your HYUNDAI vehicle air condition- ing system is filled with R-1234yf
refrigerant.
1. Start the vehicle.
2. Press the air conditioning button.
3. Select the Face Level mode.
4. Set the air intake control toRecirculation mode temporarily to
allow the cabin to cool quickly.
When the desired temperature inthe cabin is reached, change the
air intake control back to Fresh
mode.
5. Adjust the fan speed control and temperature control to maintain
maximum comfort.
When maximum cooling is desired,
set the temperature control to the
MAX A/C position, then set the fanspeed control to the highest setting. When using the air conditioning
system, monitor the temperature
gauge closely while driving up
hills or in heavy traffic when out-
side temperatures. Air condition-
ing system operation when climb-ing a steep grade or in high out-side ambient temperatures can
cause fuel cell stack overheating.
Continue to use the fan, but turn the air conditioning system off if
the temperature gauge indicates
fuel cell stack overheating.
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 recircu-
lation 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 airconditioning system with the win-
dows and sunroof closed.
Use the air conditioning system every month only for a few minutes
to ensure maximum system per-
formance.
If you operate air conditioner exces- sively, the difference between the
temperature of the outside air andthat 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
knob or button to the position
and fan speed control to the lowerspeed.

System Maintenance
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.

Air Conditioning refrigerant label
You can find out which air condition-
ing refrigerant is applied to your vehi-cle on the label located inside of thehood.Each symbols and specification on
the air conditioning refrigerant label
is represented as below:
1. Classification of refrigerant
2. Amount of refrigerant
3. Classification of compressor lubri-
cant
4. Caution
5. Flammable refrigerant
6. To require registered technician to service air conditioning system
7. Service manual
Vehicles equipped with R-1234yf
Since the refrigerant is
mildly flammable andoperated at high pres-
sure, the air condition-
ing system should only
be serviced by trained
and certified techni-
cians. It is important
that the correct type and amount
of oil and refrigerant are used.
All refrigerants should be
reclaimed with proper equipment.
Venting refrigerants directly to the atmosphere is harmful to individu-
als and environment. Failure toheed these warnings can lead toserious injuries.

discharged.
Noise and vibration generated during braking is normal.
Under normal operation, electric brake pump noise and motor
vibration may occur temporarily
in below cases.
- When the pedal is depressedsuddenly.
- When the pedal is repeatedly depressed in short intervals.
- When the ABS function is acti- vated while braking.
Disc Brake Wear Indicator

new pads are required, you will hear
a high pitched warning sound from
your front or rear brakes. You mayhear this sound come and go or it
may occur whenever you depress
the brake pedal.
Note that some driving conditions or
climates may cause a brake squeal
when you first apply (or lightly apply)
the brakes. This is normal and does
not indicate a problem with your
brakes.
To avoid costly brake repairs, do
not continue to drive with wornbrake pads.
Information
Always replace brake pads as com-
plete front or rear axle sets.

Driving your vehicle
Do not allow wheel(s) of oneaxle to spin excessively while
the ESC, ABS, and parking brake
warning lights are displayed.
The repairs would not be cov-
ered by the vehicle warranty.
Reduce vehicle power and do
not spin the wheel(s) excessive-

played.
When operating the vehicle on a dynamometer, make sure theESC is turned off (ESC OFF lightilluminated).
Information
Turning the ESC off does not affect

Vehicle Stability Management (VSM)
The Vehicle Stability Management (VSM) is a function of the Electronic
Stability Control (ESC) system. It
helps ensure the vehicle stays stable
when accelerating or braking sud-
denly on wet, slippery and rough
roads where traction over the four
tires can suddenly become uneven.
VSM operation
VSM ON condition
The VSM operates when:
The Electronic Stability Control (ESC) is on.
Vehicle speed is approximately above 15 km/h (9 mph) on curve
roads.
Vehicle speed is approximately above 30 km/h (18 mph) when the
vehicle is braking on rough roads.
When operating
When you apply your brakes under
conditions which may activate the
ESC, you may hear sounds from the
brakes, or feel a corresponding sen-
sation in the brake pedal. This is nor-
mal and it means your VSM is active.
i
NOTICE
Take the following precautions
when using the Vehicle Stability
Management (VSM):
ALWAYS check the speed and
the distance to the vehicle
ahead. The VSM is not a substi-
tute for safe driving practices.
Never drive too fast for the
road conditions. The VSM sys-
tem will not prevent acci-
dents. Excessive speed in bad
weather, slippery and uneven
roads can result in severeaccidents.
