What to Expect After an Air
Bag Inflates
After a frontal or side air bag inflates,
it will deflate very quickly. Air bag
inflation will not prevent the driverfrom seeing out of the windshield or
being able to steer. Curtain air bags
may remain partially inflated for
some time after they deploy.
Noise and smoke from inflatingair bag
When the air bags inflate, they make
a loud noise and may produce
smoke and powder in the air inside of
the vehicle. This is normal and is aresult of the ignition of the air bag
inflator. After the air bag inflates, you
may feel substantial discomfort inbreathing because of the contact of
your chest with both the seat belt and
the air bag, as well as from breathing
the smoke and powder. The powder
may aggravate asthma for some
people. If you experience breathing
problems after an air bag deploy-ment, seek medical attention imme-
diately.
Though the smoke and powder are
nontoxic, they may cause irritation to
the skin, eyes, nose, throat, etc. If
this is the case, wash and rinse with
cold water immediately and seekmedical attention if the symptomspersist.
Always wash exposed skin
areas thoroughly with coldand mild soap.
Always have an authorized
HYUNDAI dealer replace the
air bag immediately after
deployment. Air bags are
designed to be used only
once.
After an air bag inflates, take
the following precautions:
Open your windows and doors
as soon as possible after
impact to reduce prolonged
exposure to the smoke and
powder released by the inflat-
ing air bag.
Do not touch the air bag stor-
age area's internal compo-
nents immediately after an air
bag has inflated. The partsthat come into contact with an
inflating air bag may be veryhot.

or ice on the windshield, defrost the
windshield for about 10 minutes, or
until the snow and/or ice is removed
before using the windshield wipers to
ensure proper operation.
If you do not remove the snow and/or
ice before using the wiper and washer,
it may damage the wiper and washer
system.AUTO - Automatic Wiper Control (if equipped)
A rain sensor located near the wind-
shield detects moisture accumula-tion and controls the wiping cycle
automatically. This mode is designed
to operate the wiper at an appropri-ate speed depending on the amount
of rainfall. The sensitivity can be var-
ied by turning the adjustment control
(B) located on the wiper stalk. If the
wiper switch is set in AUTO mode
when the ignition switch is in the ON
position, the wiper will operate once
to perform a self-check of the sys-
tem. Set the wiper control to the OFFposition when the windshield wipersare not required.

Maintenance
1122VV BB AA TTTTEERR YY
The vehicle is not equipped with a
common 12V battery which requires
periodic replacement. The battery is
a lithium polymer type integrated into
the high voltage battery. Full dis-
charge of the battery is prevented
through 12V battery protection sys-tem which can isolate the 12V bat-
tery.
To prevent SERIOUS INJURY or
DEATH to you or bystanders,
always follow these precautions
when working near or handling
the battery: Always read and follow
instructions carefully
when handling a battery.
Wear eye protection
designed to protect the
eyes from acid splashes.
Keep all flames, sparks, or smoking materials
away from the battery.
WARNING
Hydrogen is always present in battery cells,
is highly combustible,
and may explode if ignit-ed.
Keep batteries out of
reach of children. Batteries contain sulfu-
ric acid which is highly
corrosive. Do not allow
acid to contact your
eyes, skin or clothing.
If acid gets into your eyes, flush
your eyes with clean water for at
least 15 minutes and get imme-
diate medical attention. If acid
gets on your skin, thoroughly
wash the area. If you feel pain or
a burning sensation, get med-
ical attention immediately.When lifting a plastic-cased
battery, excessive pressure
on the case may cause battery
acid to leak. Lift with a battery
carrier or with your hands on
opposite corners.
Do not attempt to jump start
your vehicle if your battery is
frozen.
NEVER attempt to recharge
the battery when the vehicle’s
battery cables are connected
to the battery.
The electrical ignition system
works with high voltage.
NEVER touch these compo-
nents with the vehicle ON
( indicator ON) or when
the POWER button is in theON position.

1. Does a Hydrogen Fuel Cell Electric Vehicle (FCEV) have similar performance
to standard, non-electric vehicles?FCEV performance characteristics are generally equivalent to stan-
dard vehicles, but with better noise control.
2. If water floods the fuel cell power modulecompartment, due to heavy rain or flood-
ing for example, will it have any effect on
the vehicle?
Every component housed in the fuel cell power module compart-
ment is designed to be waterproof through evaluation which meets
the IP69K standard, so you don't have to worry about any potential
faults or safety problems if water contacts the fuel cell. However, if
the vehicle is fully flooded, have the vehicle checked by an author-
ized HYUNDAI dealer.
3. When starting or stopping the vehicle,there's a noise. Is this noise cause for
concern?
The sound you hear is normal. The noise emanates from the blower
motor starting up to remove any residual water vapor in the fuel cellsystem. Also, when you turn on the vehicle you may hear a brief oper-
ation sound from the hydrogen storage system which is located on the
back of the vehicle. This is a normal sound which is occurred when the
system tries to balance the pressure between the hydrogen tanks.
4. Is there a possibility that extremely cold weather can prevent vehicle startup?
In most instances, the vehicle can get startup in cold weather with-
out any problems. However, the vehicle may not start if the vehicle is
parked with the ignition off for over a week in cold temperatures. In
this case, turn on the vehicle 2-3 times repeatedly. If you will not be
turning on the ignition for more than a week in cold weather, it is
recommended that you park the vehicle inside a building, if possible. Notice)
In particular, make sure to park the vehicle indoor when the temper-
ature is below -30°C. If the vehicle is parked outside for over 12
hours under such weather fuel cell components may be damaged.
Also, avoid driving under such weather to prevent damaging the fuel
cell components.

Explosion or
Fire (5 items)
48. What should I do if the FCEV catches fire?
1. stop driving the car. Move the shift to P (Park) , then step on thebrake to turn OFF the vehicle. The fuel cell stack is shut down,
which cuts off the supply of hydrogen fuel.
2. If possible, open the windows to ventilate the air.
3. If the fire is small enough to get under your own control, use the fire extinguisher to put it out.
If the fire is much larger, get out of your car and contact the local
fire station to report your FECV is on fire. DO NOT get close to your
car before the fire is completely extinguished.
49. In case of vehicle fire, should I use the fire extinguisher? Can I use water to
extinguish the fire?
In the event your FCEV catches fire with the power system OFF, the
power source of the high-voltage system is cut off, so you are unlikely
to get shocked while you put out the fire using water. (Even when the
vehicle is submerged in water, there is no risk of getting shocked.)
However, if your car catches fire with the ignition ON, you MUST use
the fire extinguisher. Any attempt to extinguish the fire with water may
cause electric shock.
50. What kind of fire extinguisher should Iuse?It is recommended that you use a dedicated fire extinguisher (CO2)
for an electrical fire of the high-voltage system.
51. Can the hydrogen tank explode if itoverheats in very hot weather?The hydrogen tank passed a high temperature test and is deemed
safe, so it is unlikely to explode.
52. In case of vehicle fire, is it possible that
the hydrogen tank will explode?
In case of vehicle fire, a heat-sensitive safety valve is activated to
exhaust the hydrogen gas downward from the tank by force.
Therefore, the hydrogen tank is unlikely to explode. However, addi-
tional flames can flare up from the forced exhaustion of the gas, so
please evacuate to a safe place far away from the vehicle.
