Hazardous Driving Conditions
When hazardous driving elements
are encountered such as water,
snow, ice, mud and sand, take the
bellow suggestions:
Drive cautiously and keep a longerbraking distance.
Avoid abrupt braking or steering.
When your vehicle is stuck in snow, mud, or sand, use second gear.
Accelerate slowly to avoid unnec-
essary wheel spin.
Put sand, rock salt or other non- slip materials under the wheels to
provide additional traction while
the vehicle becomes stuck in ice,
snow, or mud.
Rocking the Vehicle
If it is necessary to rock the vehicle
to free it from snow, sand, or mud,
first turn the steering wheel right and
left to clear the area around your
front wheels. Then, shift back and
forth between R (Reverse) and a for-
ward gear.
Try to avoid spinning the wheels, and
do not race the vehicle.
To prevent reduction gear wear, wait
until the wheels stop spinning before
shifting gears. Release the accelera-tor pedal while shifting, and press
lightly on the accelerator pedal while
the reduction gear is in gear. Slowly
spinning the wheels in forward and
reverse directions causes a rocking
motion that may free the vehicle.
SSPP EECCIIAA LL DD RRIIVV IINN GG CC OO NNDDIITT IIOO NNSS
If the vehicle is stuck and
excessive wheel spin occurs,the temperature in the tires can
increase very quickly. If the tires
become damaged, a tire blow
out or tire explosion can occur.
This condition is dangerous -
you and others may be injured.
Do not attempt this procedure if
people or objects are anywhere
near the vehicle.
If you attempt to free the vehi-
cle, the vehicle can overheat
quickly, possibly causing an
fuel cell power module com-
partment fire or other damage.
Try to avoid spinning the
wheels as much as possible to
prevent overheating of either
the tires or the vehicle. DO NOT
allow the vehicle to spin the
wheels above 56 km/h (35 mph).
WARNING

Driving your vehicle
Do not let ice and snow accu-mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
car to be sure the movement of the
front wheels and the steering com-
ponents is not obstructed.
Don't place foreign objects ormaterials in the fuel cell power
module compartment
Placement of foreign object or mate-
rials which prevent cooling of the
vehicle, in the fuel cell power module
compartment, may cause a failure.
The manufacturer is not responsible
for the damage caused by suchplacement.
To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.

Two labels on your driver's door sill
show how much weight your vehicle
was designed to carry: the Tire and
Loading Information Label and the
Certification Label.
Before loading your vehicle, familiar-
ize yourself with the following terms
for determining your vehicle's weight
ratings, from the vehicle's specifica-
tions and the Certification Label:
Base Curb Weight
This is the weight of the vehicle including a full tank of fuel and all
standard equipment. It does not
include passengers, cargo, or option-al equipment.
Vehicle Curb Weight
This is the weight of your new vehicle
when you picked it up from your deal-
er plus any aftermarket equipment.
Cargo Weight
This figure includes all weight added
to the Base Curb Weight, includingcargo and optional equipment.GAW (Gross Axle Weight)
This is the total weight placed on each axle (front and rear) - including
vehicle curb weight and all payload.
GAWR (Gross Axle Weight Rating)
This is the maximum allowable
weight that can be carried by a single
axle (front or rear). These numbers
are shown on the Certification Label.
The total load on each axle must
never exceed its GAWR.
GVW (Gross Vehicle Weight)
This is the Base Curb Weight plus
actual Cargo Weight plus passengers.
GVWR (Gross Vehicle Weight Rating)
This is the maximum allowable
weight of the fully loaded vehicle
(including all options, equipment,
passengers and cargo). The GVWR
is shown on the Certification Label
located on the driver’s door sill.Tire Loading Information Label

Certification label
The certification label is located on
the driver’s door sill at the center pil-
lar and shows the maximum allow-
able weight of the fully loaded vehi-
cle. This is called the GVWR (Gross
Vehicle Weight Rating). The GVWR
includes the weight of the vehicle, all
occupants, fuel and cargo.
This label also tells you the maxi-
mum weight that can be supported
by the front and rear axles, called
Gross Axle Weight Rating (GAWR).
The total weight of the vehicle,
including all occupants, accessories,
cargo, and trailer tongue load must
not exceed the Gross Vehicle WeightRating (GVWR) or the Gross Axle
Weight Rating (GAWR). To find out
the actual loads on your front and
rear axles, you need to go to a weigh
station and weigh your vehicle. Be
sure to spread out your load equally
on both sides of the centerline.Overloading your vehicle may
cause damage. Repairs would not
be covered by your warranty. Do
not overload your vehicle.
NOTICE
Overloading
Never exceed the GVWR for
your vehicle, the GAWR for
either the front or rear axle
and vehicle capacity weight.Exceeding these ratings can
affect your vehicle's handling
and braking ability, and causean accident.
Do not overload your vehicle.
Overloading your vehicle can
cause heat buildup in your
vehicle's tires and possible
tire failure, increased stop-ping distances and poor vehi-
cle handling-all of which mayresult in a crash.
WARNING

6-2
The hazard warning flasher serves
as a warning to other drivers to exer-
cise extreme caution when approach-
ing, overtaking, or passing your vehi-
cle.
It should be used whenever emer- gency repairs are being made or
when the vehicle is stopped near the
edge of a roadway. To turn the hazard warning flasher
on or off, press the hazard warning
flasher button. The button is located
in the center fascia panel. Both the
left and right turn signal lights will
flash simultaneously.
• The hazard warning flasher oper-
ates whether your vehicle is run- ning or not.
The turn signals do not work when the hazard flasher is on.
If an accident occurs
1. Stop the vehicle, shift gear to the P (Park) position, engage the
parking brake, and turn the vehicle
off.
The flow of hydrogen into the fuel cell stack will be shut off to prevent
the electricity from being generat-ed.
2. Evacuate to the safety place.
3. Call emergency services for help and let them know the vehicle is a
Fuel Cell Electric Vehicle.

What to do in an emergency
If a fire occurs
1. Stop the vehicle, shift gear to theP(Park) position, engage the park-
ing brake, and turn the vehicle off.
The flow of hydrogen into the fuel cell stack will be shut off to prevent
the electricity from being generat-ed.
2. If the fire is small, which can be extinguished with fire extinguisher,
use carbon dioxide extinguisher.
You can also extinguish the fire with water when the vehicle power
is turned off. If the fire is too big to be extin-
guished with the fire extinguisher,
evacuate from the vehicle, call the
fire department, and let them know
the vehicle is a Fuel Cell Electric
Vehicle. Do not come close to the
vehicle until the fire is totally extin-guished.
Emergency venting of hydro-
gen gas
If the temperature near the safety
valve located at the rear under vehi-
cle is over 110°C (230°F) caused by
a fire or other reasons, the safety
valve will open to vent hydrogen gas.
Venting the hydrogen gas makes a
loud noise because the venting
speed is very fast. Stay well away
from the vehicle. The discharge of
hydrogen gas from the vehicle is
flammable and could cause a fire.
If a submersion in water
occurs
If your vehicle was flooded and has
soaked carpeting or water on the
flooring, you should not try to start
the vehicle by pressing the POWER
button.
Contact an authorized HYUNDAI
dealer immediately.
If the vehicle stalls at a cross-
road or crossing
If the vehicle stalls at a crossroad or crossing, set the gear in the N
(Neutral) position and then push the
vehicle to a safe place.

Do not use water to extinguish a
fire when the vehicle power is
turned on. Serious electric
shock may result.
WARNING

If you have a flat tire while driving
If a tire goes flat while you are driv- ing:
1. Take your foot off the acceleratorpedal and let the vehicle slow
down while driving straight ahead.
Do not apply the brakes immedi-ately or attempt to pull off the road
as this may cause a loss of con-
trol. When the vehicle has slowed
to such a speed that it is safe to do
so, brake carefully and pull off the
road. Drive off the road as far as
possible and park on firm, level
ground. If you are on a divided
highway, do not park in the medi-
an area between the two traffic
lanes.
2. When the vehicle is stopped, turn on your emergency hazard flash-
ers, set the parking brake and shift
gear to the P(Park) position.
3. Have all passengers get out of the vehicle. Be sure they all get out on
the side of the vehicle that is away
from traffic.
If the vehicle stalls while driv- ing
1. Reduce your speed gradually,keeping a straight line. Move cau-
tiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Try to start the vehicle again. If your vehicle will not start, contact
an authorized HYUNDAI dealer. Be sure the shift lever is in P
(Park). The vehicle starts only
when the shift lever is in P (Park).
This vehicle does not have a regu- lar 12V battery that needs periodic
replacement. It is lithium ion poly-
mer type integrated into the high
voltage battery. The vehicle has a
12V battery protection system that
cuts 12V battery from vehicle draw
to prevent full discharge. If vehicle
will not start, first try pressing the
12V Battery Reset switch (left side
of the steering wheel near the fuel
door open switch) to reconnect the
12V battery, but you must start
vehicle within 15 seconds of press-
ing the 12V Battery Reset switch.
After starting vehicle, operate the
vehicle safely outdoors in ready
mode stopped and/or drive it for 30
minutes total to charge the 12V
battery fully.
Check the fuel level and add fuel if necessary.
Do not push or pull the vehicle to start it.
If the vehicle still does not start, call
an authorized HYUNDAI dealer for
assistance.
