Driving your vehicle
When using tire chains:
Wrong size chains or improperly
installed chains can damage
your vehicle's brake lines, sus-
pension, body and wheels.
Use SAE "S" class or wire
chains.
If you hear noise caused by
chains contacting the body,
retighten the chain to prevent
contact with the vehicle body.
To prevent body damage,
retighten the chains after driving
0.3~0.6 miles (0.5~1.0 km).
Do not use tire chains on vehi-
cles equipped with aluminum
wheels. If unavoidable, use a
wire type chain.
Use wire chains less than 0.47 in
(12 mm) thick to prevent damage
to the chain's connection.
Winter Precautions
Use high quality ethylene glycol
coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Use approved window washer
anti-freeze in system
To keep the water in the window
washer system from freezing, add an
approved window washer anti-freeze
solution in accordance with instruc-
tions on the container. Window wash-
er anti-freeze is available from an
authorized HYUNDAI dealer and
most auto parts outlets. Do not use
coolant or other types of anti-freeze
as these may damage the paint fin-
ish.
Do not let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to happen
when there is an accumulation of
snow or ice around or near the rear
brakes or if the brakes are wet. If
there is a risk the parking brake may
freeze, apply it only temporarily while
you shift to P (Park) and block the
rear wheels so the car cannot roll.
Then release the parking brake.

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 or
materials 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 such
placement.
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.

Driving your vehicle
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, including
cargo 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 passen-
gers.
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.

The label located on the driver's door
sill gives the original tire size, cold
tire pressures recommended for your
vehicle, the number of people that
can be in your vehicle and vehicle
capacity weight.
Vehicle capacity weight
903 lbs. (410 kg)
Vehicle capacity weight is the maxi-
mum combined weight of occupants
and cargo. If your vehicle is equipped
with a trailer, the combined weight
includes the tongue load.
Seating capacity
Total : 5 persons
(Front seat : 2 persons,
Rear seat : 3 persons)
Seating capacity is the maximum
number of occupants including a
driver, your vehicle may carry.
However, the seating capacity may
be reduced based upon the weight of
all of the occupants, and the weight
of the cargo being carried or towed.
Do not overload the vehicle as there
is a limit to the total weight, or load
limit including occupants and cargo,
the vehicle can carry.
Towing capacity
We do not recommend using this
vehicle for trailer towing.
Cargo capacity
The cargo capacity of your vehicle
will increase or decrease depending
on the weight and the number of
occupants and the tongue load, if
your vehicle is equipped with a trailer.
Steps for determining correct
load limit
1. Locate the statement "The com-
bined weight of occupants and
cargo should never exceed XXX
kg or XXX lbs." on your vehicle's
placard.
2. Determine the combined weight of
the driver and passengers that will
be riding in your vehicle.
3. Subtract the combined weight of
the driver and passengers from
XXX kg or XXX lbs.
4. The resulting figure equals the
available amount of cargo and lug-
gage load capacity. For example, if
the "XXX" amount equals 1400
lbs. and there will be five 150 lb
passengers in your vehicle, the
amount of available cargo and lug-
gage load capacity is 650 lbs.
(1400 - 750 (5 x 150) = 650 lbs.)
5. Determine the combined weight of
luggage and cargo being loaded
on the vehicle. That weight may
not safely exceed the available
cargo and luggage load capacity
calculated in Step 4.

Driving your vehicle
6. If your vehicle will be towing a trail-
er, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and
luggage load capacity of your vehi-
cle.
Do not overload the vehicle as
there is a limit to the total
weight, or load limit, including
occupants and cargo, the vehi-
cle can carry. Overloading can
shorten the life of the vehicle. If
the GVWR or the GAWR is
exceeded, parts on the vehicle
can break, and it can change the
handling of your vehicle. These
could cause you to lose control
and result in an accident.

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 Weight
Rating (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.
OBH059070
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 cause
an 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 may
result in a crash.

If you carry items inside your
vehicle (e.g., suitcases, tools,
packages, or anything else),
they are moving as fast as the
vehicle. If you have to stop or
turn quickly, or if there is a
crash, the items will keep going
and can cause an injury if they
strike the driver or a passenger.
Put items in the cargo area of
your vehicle. Try to spread the
weight evenly.
Do not stack items, like suit-
cases, inside the vehicle
above the tops of the seats.
Do not leave an unsecured
child restraint in your vehicle.
When you carry something
inside the vehicle, secure it.

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.
