Driving your vehicle
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, tire chains or other non-slip materials under the
wheels to provide additional trac-
tion 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.

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).

Information
The ESC system (if equipped) must be
turned OFF before rocking the vehi-
cle.
If you are still stuck after rocking
the vehicle a few times, have the
vehicle pulled out by a tow vehicle
to avoid vehicle overheating, pos-
sible damage to the reduction
gear and tire damage. See
"Towing" in chapter 6.
Smooth Cornering
Avoid braking or gear changing in
corners, especially when roads are
wet. Ideally, corners should always
be taken under gentle acceleration.
Driving at Night
Night driving presents more hazards
than driving in the daylight. Here are
some important tips to remember:
Slow down and keep more dis-tance between you and other vehi-
cles, as it may be more difficult to
see at night, especially in areas
where there may not be any street
lights.
Adjust your mirrors to reduce the glare from other driver's head-
lamps.
Keep your headlamps clean and properly aimed. Dirty or improperly
aimed headlamps will make it
much more difficult to see at night.
Avoid staring directly at the head- lamps of oncoming vehicles. You
could be temporarily blinded, and it
will take several seconds for your
eyes to readjust to the darkness.
Driving in the Rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or
on slick pavement:
Slow down and allow extra follow-ing distance. A heavy rainfall
makes it harder to see and increas-
es the distance needed to stop
your vehicle.
Turn OFF your Cruise Control. (if equipped)
Replace your windshield wiper blades when they show signs of
streaking or missing areas on the
windshield.
Be sure your tires have enough tread. If your tires do not have
enough tread, making a quick stop
on wet pavement can cause a skid
and possibly lead to an accident.
See "Tire Tread" in chapter 7.
Turn on your headlamps to make it easier for others to see you.
Driving too fast through large pud- dles can affect your brakes. If you
must go through puddles, try to
drive through them slowly.
NOTICE
i

5-120
Driving your vehicle
If you believe your brakes may be wet, apply them lightly while driv-
ing until normal braking operation
returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the
water. The best advice is SLOW
DOWN when the road is wet.
The risk of hydroplaning increas-
es as the depth of tire tread
decreases, refer to "Tire Tread" in
chapter 7.
Driving in Flooded Areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
reduced.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.
Highway Driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or
damage the tires.
Do not install worn-out or damaged
tires, which may reduce traction or
fail the braking operation.
Information
Never over-inflate your tires above the
maximum inflation pressure, as speci-
fied on your tires.
Coolant and high voltage bat-tery
Be sure to check both the coolant
level and the high voltage battery
level before driving.
i

5-122
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

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.

Low Tire Pressure
LCD Display with
Position Indicator
When the tire pressure monitoring
system warning indicators are illumi-
nated and the warning message is
displayed on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The LCD posi-
tion indicator will indicate which tire
is significantly under-inflated by illu-
minating the corresponding position
light. If any of your tire pressures are indi-
cated as being low, immediately
reduce your speed, avoid hard cor-
nering, and anticipate increased
stopping distances. You should stop
and check your tires as soon as pos-
sible. Inflate the tires to the proper
pressure as indicated on the vehi-
cle’s placard or tire inflation pressure
label located on the driver's side cen-
ter pillar outer panel.
The Low Tire Pressure LCD position
indicator will remain on and the
TPMS Malfunction Indicator may
blink for one minute and then remain
illuminated until you have the low
pressure tire repaired and replaced
on the vehicle.
NOTICE
OFE068005L

6-16
What to do in an emergency
You may not be able identify a tire
with low pressure by simply looking
at it. Always use a good quality tire
pressure gage to measure the tire's
inflation pressure. Please note that a
tire that is hot (from being driven) will
have a higher pressure measure-
ment than a tire that is cold.
A cold tire means the vehicle has
been sitting for 3 hours and driven for
less than 1 mile (1.6 km) in that 3
hour period.
Allow the tire to cool before measur-
ing the inflation pressure. Always be
sure the tire is cold before inflating to
the recommended pressure.

Maintenance
Owner maintenance schedule
When you stop for fuel:
• Check for both fuel cell stack andDevice cooling coolant level in
coolant reservoir.
Check the windshield washer fluid level.
Look for low or under-inflated tires.
While operating your vehicle:
Check for vibrations in the steering wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
Notice if your vehicle constantly turns slightly or "pulls" to one side
when traveling on smooth, level
road.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or "hard-to-push" brake pedal.
If any slipping or changes in the operation of your reduction gear
occurs, check the reduction gear
fluid level.
Check the reduction gear P (Park) function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check coolant level in the coolantreservoir.
Check the operation of all exterior lights, including the brake lights,
turn signals and hazard warning
flashers.
Check the inflation pressures of all tires that are worn, show uneven
wear, or are damaged.
Check for loose wheel lug nuts.
At least twice a year: (i.e., every Spring and Fall)
Check radiator, heater and air con-
ditioning hoses for leaks or dam-
age.
Check windshield washer spray and wiper operation. Clean wiper
blades with clean cloth dampened
with washer fluid.
Check headlamp alignment.
Check the seat belts for wear and function.
Be careful when checking the
coolant level when the fuel cell
power module is hot. Scalding
hot coolant and steam may
blow out under pressure. This
could cause burns or other seri-
ous injury.
