LFA operation
The driver can turn on the LFA sys-
tem with the vehicle on and by
selecting "Vehicle settings →Driver
assistance →Driving assist →LFA
(Lane Following Assist)" in the AVN
screen.
The set-up of the LFA system will be
maintained, as selected, when the
vehicle is restarted.
Driving your vehicle
The system detects lane
markers and controls the
steering wheel by a camera,
therefore, if the lane markers
are hard to detect, the system
may not work properly.
Please refer to "Limitations of
the system".
Do not remove or damage the
related parts of LFA system.
You may not hear a warning
sound of LFA system because
of excessive audio sound.
Do not place objects on the
dashboard that reflects light
such as mirrors, white paper,
etc. The system may malfunc-
tion if the sunlight is reflected.
Always have your hands on
the steering wheel while the
LFA system is activated. If you
continue to drive with your
hands off the steering wheel
after the "Keep hands on
steering wheel" warning mes-
sage appears, the system will
be turned off automatically.
However, if the driver has their
hands on the steering wheel
again, the system will start
controlling the steering wheel.
The steering wheel may not
be continuously controlled by
the system if the vehicle
speed is too high. The driver
must always follow the speed
limit when using the system.
If you attach objects to the
steering wheel, the system
may not assist steering nor-
mally or the hands off alarm
may not work properly.
When you tow a trailer, make
sure that you turn off the LFA
system.

Warning message
Keep hands on steering wheel
If the driver takes their hands off from
the steering wheel for certain time
while the LFA system is activated,
the system will warn the driver.
Information
If the steering wheel is held very light-
ly the message may still appear
because the LFA system may not rec-
ognize that the driver has their hands
on the wheel.
Driver's grasp not detected.
LFA system is disabled temporarily
If the driver still does not have their
hands on the steering wheel after the
message "Keep hands on steering
wheel", the system will not control
the steering wheel and warn the driv-
er only when the driver crosses the
lane markers.
However, if the driver has their hands
on the steering wheel again, the sys-
tem will start controlling the steering
wheel.
i
Driving your vehicle
The warning message may
appear late according to road
conditions. Therefore, always
have your hands on the steering
wheel while driving.

The Driver Attention Warning sys-
tem utilizes the camera sensor on
the front windshield for its opera-
tion. To keep the camera sensor in
the best condition, you should
observe the followings:
Do not disassemble the camera
temporarily to tint the window or
to attach any types of coatings
and accessories. If you disas-
semble a camera and assemble
it again, take your vehicle to an
authorized HYUNDAI dealer and
have the system checked for cal-
ibration.
NEVER install any accessories
or stickers on the front wind-
shield, nor tint the front wind-
shield.
NEVER locate any reflective
objects (i.e. white paper, mirror)
over the dashboard. Any light
reflection may cause a malfunc-
tion of the Driver Attention Alert
(DAW) system.
Pay extreme caution to keep the
camera sensor out of water.
NOTICE
The Driver Attention Warning
(DAW) system may not properly
operate with limited alerting in
the following situations:

ance is limited. (For more
details, refer to "Lane Keeping
Assist (LKA) system" in this
chapter.)
The vehicle is violently driven
or is abruptly turned for obsta-
cle avoidance (e.g. construc-
tion area, other vehicles, fallen
objects, bumpy road).
Forward drivability of the vehi-
cle is severely undermined
(possibly due to wide variation
in tire pressures, uneven tire
wear-out, toe-in/toe-out align-
ment).
The vehicle drives on a curvy
road.
The vehicle drives on a bumpy
road.
The vehicle drives through a
windy area.
The vehicle is controlled by the
following driving assist sys-
tems:

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 longer
braking distance.
Avoid abrupt braking or steering.
When your vehicle is stuck in snow,
mud, or sand, turn off the vehicle.
Remove the mud, snow or sand
from around the front wheels and
restart the vehicle. Accelerate
slowly to avoid unnecessary 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).
WARNING

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.

ing for approximately 1 minute.
3. The Low Tire Pressure LCD dis-
play remains illuminated
Low Tire Pressure
Telltale
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.
