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 to
skid.
To drive your vehicle in deep snow, it
may be necessary to use snow tires
or to install tire chains on your tires.
Always carry emergency equipment.
Some of the items you may want to
carry include tire chains, tow straps
or chains, a flashlight, emergency
flares, sand, a shovel, jumper cables,
a window scraper, gloves, ground
cloth, coveralls, 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, state and munici-
pal regulations for possible restric-
tions 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 50°F (10°C).
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.
WARNING

H7
OFEQ018010
•Do not disassemble or assem-
ble the high voltage battery
system. Doing so may result
in electric shock causing
death or serious injury.
If you disassemble or assem-
ble system components
improperly, it may damage the
performance and reliability of
your vehicle.
If coolant and electrolyte
come in contact with your
body, clothes or eyes, immedi-
ately flush with a large quanti-
ty of fresh tap water. Have
your eyes examined by a doc-
tor as soon as possible.
WARNING
Never assemble or disassemble
the high voltage battery system.
If you assemble or disassem-
ble the high voltage battery
system, the durability and
performance of the vehicle
may be damaged.
When you want to check the
high voltage battery system,
contact an authorized
HYUNDAI dealer.
Do not touch the high voltage
battery and high voltage cable
connected to motor (orange
color). Severe burns and elec-
tric shock may occur. For your
safety, do not touch the cover
of electronic components and
electronic cable. Do not
remove the cover of electron-
ic components and electronic
cable. In particular, never
touch the high voltage battery
system when the FCEV sys-
tem is operating. It may result
in death or serious injury.
WARNING
Never use the package mod-
ules (high voltage battery,
inverter, converter) for any
other purpose.
Do not use an after-market
battery charger to charge the
high voltage battery. Doing so
may result in death or serious
injury.
Never get near or put a high
voltage battery system in a
fire. Doing so may result in
serious burns.
Never drill into, strike or oth-
erwise damage the package
modules. An electric shock
may occur resulting in seri-
ous injury or death.
WARNING

H11
How to Stop the Vehicle
1. Hold down the brake pedal whilethe vehicle is parked.
2. While depressing the brake pedal, shift to P (Park).
3. While depressing the brake pedal, engage the parking brake.
4. While depressing the brake pedal, press the Power button and turn
off the vehicle.
5. Check if the " " indicator is turned OFF on the instrument
cluster.
When the " " indicator is ON and the gear is in a position other
than P (Park), the driver can acci-
dently depress the accelerator
pedal, causing the vehicle to move
unexpectedly.
Virtual Engine Sound System
The Virtual Engine Sound System
generates engine sound for pedestri-
ans to hear vehicle sound because
there is no sound while the FCEV
vehicle is operating.
• If the vehicle is in the ready ( ) mode and the gear is not in P
(Park),
When the gear is shifted to R (Reverse), an additional warning
sound will be heard.
The vehicle does not generate
a sound. Be aware of your
driving environment and drive
safely.
After you park the vehicle or
while you are waiting at a traf-
fic light, check whether there
are children or obstacles
around the vehicle.
Check if there is something
behind the vehicle when driv-
ing in reverse. Pedestrians
may not hear the sound of the
vehicle.

(10 items)
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 cell
system. 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.

21. Tell me what the potential effects are ofparking long-term in a cold area (-4 °F
(-20 °C)) for the FCEV, and whether or
not the vehicle can startup under such
conditions.In most instances, the vehicle can get startup in cold weather with-
out any problems. However, the vehicle may not start if it is parked
with the power off for over a week in cold temperatures. In this case,
If you will not be turning on the vehicle for more than a week in cold
weather, it is recommended that you park the vehicle inside a build-
ing, if possible.
22. What parts must I not touch withhands? For example, high-voltage
cable, ion filter, etc.?
High-voltage cable (orange color), ion filter, parts with a high voltage
