Limitations of the System
The LKA system may operate pre-
maturely even if the vehicle does not
depart from the intended lane, OR,
the LKA system may not warn you if
the vehicle leaves the intended lane
under the following circumstances:
When the lane and road condi-
tions are poor
It is difficult to distinguish the lane
marker from the road because the
lane marker is covered with dust or
sand.
It is difficult to distinguish the color
of the lane marker from the road.
There are markings on the road
surface that look like a lane marker
that is inadvertently being detected
by the camera.

damaged.
The lane marker is merged or
divided. (e.g. tollgate)
The lane number increases or
decreases or the lane marker are
crossing complicatedly.
There are more than two lane
markers on the road in front of you. The lane marker is very thick or
thin.

The lane marker ahead is not visible
due to rain, snow, water on the
road, damaged or stained road sur-
face, or other factors.
The shadow is on the lane marker
by a median strip, trees, guardrail,
noise barriers, etc.
The lane markers are complicated
or a structure substitutes for the
lines such as a construction area.
There are crosswalk signs or other
symbols on the road.
The lane marker in a tunnel is
stained with oil, etc.
The lane suddenly disappears
such as at the intersection.
When external condition is inter-
vened
The brightness outside changes
suddenly such as when entering or
exiting a tunnel, or when passing
under a bridge. The brightness outside is too low
such as when the headlamps are
not on at night or the vehicle is
going through a tunnel.
There is a boundary structure in
the roadway such as a concrete
barrier, guardrail and reflector post
that is inadvertently being detected
by the camera.
When light coming from a street
light or an oncoming vehicle is
reflected on a wet road surface
such as a puddle in the road.
The field of view in front is
obstructed by sun glare.
There is not enough distance
between you and the vehicle in
front to be able to detect the lane
marker or the vehicle ahead is driv-
ing on the lane marker.
Driving on a steep grade, over a
hill, or when driving on a curved
road.
The adverse road conditions cause
excessive vehicle vibrations while
driving.
The surrounding of the inside rear
view mirror temperature is high
due to direct sunlight, etc.

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, especially when roads
are wet. Ideally, corners should
always be taken under gentle accel-
eration.
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.

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.

Maintenance
In an emergency, if you do not have
a spare fuse, use a fuse of the same
rating from a circuit you may not
need for operating the vehicle.
If the headlamps or other electrical
components do not work and the
fuses are OK, check the fuse panel
in the fuel cell power module com-
partment. If a fuse is blown, it must
be replaced with the same rating.Fuel cell power module com-
partment Panel Fuse
Replacement

1. Turn the vehicle off.
2. Turn all other switches OFF.
3. Remove the fuse panel cover bypressing the tap and pulling up. 4. Check the removed fuse; replace
it if it is blown. To remove or insert
the fuse, use the fuse puller in the
motor compartment fuse panel.
5. Push in a new fuse of the same rating, and make sure it fits tightly
in the clips. If it fits loosely, consult
an authorized HYUNDAI dealer.

Consult an authorized HYUNDAI
dealer to replace most vehicle light
bulbs. It is difficult to replace vehicle
light bulbs because other parts of the
vehicle must be removed before you
can get to the bulb. This is especially
true for removing the headlamp
assembly to get to the bulb(s).
Removing/installing the headlamp
assembly can result in damage to
the vehicle.
Information
The headlamp and tail lamp lenses
could appear frosty if the vehicle is
washed after driving or the vehicle is
driven at night in wet weather. This
condition is caused by temperature
difference between the lamp inside
and outside and, it does not indicate a
problem with your vehicle. When
moisture condenses in the lamp, it will
be removed after driving with the
headlamp on. The removable level
may differ depending on lamp size,
lamp position and environmental con-
dition. However, if moisture is not
removed, we recommend that your
vehicle is inspected by an authorized
HYUNDAI dealer.
Information
• A normally functioning lamp may
flicker momentarily to stabilize the
vehicle’s electrical control system.
However, if the lamp goes out after
flickering momentarily, or contin-
ues to flicker, we recommend the
system be checked by an authorized
HYUNDAI dealer.
• The parking lamp may not turn on when the parking lamp switch is
turned on, but the parking lamp
and headlamp switch may turn on
when the headlamp switch is turned
on. This may be caused by network
failure or vehicle electrical control
system malfunction. If this occurs,
we recommend the system be
checked by an authorized
HYUNDAI dealer.

•Prior to replacing a lamp, shift
to P (Park), apply the parking
brake, place the POWER but-
ton in the OFF position and
take the key with you when
leaving the vehicle to avoid
sudden movement of the vehi-
cle and to prevent possible
electric shock.
Be aware the bulbs may be
hot and may burn your fin-
gers.
