ABS cannot prevent a loss of stabili-
ty. Always steer moderately when
braking hard. Severe or sharp steer-
ing wheel movement can still cause
your vehicle to veer into oncoming
traffic or off the road.
On loose or uneven road surfaces,
operation of the anti-lock brake sys-
tem may result in a longer stopping
distance than for vehicles equipped
with a conventional brake system.
The ABS warning light ( ) will stay
on for several seconds after the
POWER button is in the ON position.
During that time, the ABS will gothrough self-diagnosis and the light
will go off if everything is normal. If
the light stays on, you may have a
problem with your ABS. Contact an
authorized HYUNDAI dealer as soon
as possible.
When you drive on a road having
poor traction, such as an icy road,
and apply your brakes continu-
ously, the ABS will be active con-
tinuously and the ABS warning
light ( ) may illuminate. Pull
your car over to a safe place and
turn the vehicle off.
Restart the vehicle. If the ABS
warning light is off, then your ABSsystem is normal.
Otherwise, you may have a prob-
lem with your ABS system.
Contact an authorized HYUNDAI
dealer as soon as possible.
Information
When you jump start your vehicle
because of a drained battery, the ABS
warning light ( ) may turn on at the
same time. This happens because of
the low battery voltage. It does not
mean your ABS is malfunctioning.
Have the battery recharged before
driving the vehicle.

NOTICE
Driving your vehicle
If the ABS warning light ( ) is
on and stays on, you may have
a problem with the ABS. Your
power brakes will work normal-
ly. To reduce the risk of serious
injury or death, contact your
HYUNDAI dealer as soon as
possible.

Hill-Start Assist Control (HAC)
The Hill-Start Assist Control (HAC)
helps prevent the vehicle from rolling
backwards when starting a vehicle
from a stop on a hill. The system
operates the brakes automatically for
approximately 5 seconds and releas-
es the brake after 5 seconds or when
the accelerator pedal is depressed.Information
 The HAC does not operate when the gear is in P (Park) or N (Neutral).
 The HAC activates even when the ESC (Electronic Stability Control) is
off. However, it does not activate,
when the ESC does not operate nor-
mally.
Good Braking Practices
Wet brakes can be dangerous! The
brakes may get wet if the vehicle is
driven through standing water or if it
is washed. Your vehicle will not stop
as quickly if the brakes are wet. Wet
brakes may cause the vehicle to pull
to one side. To dry the brakes, apply the brakes
lightly until the braking action returns
to normal. If the braking action does
not return to normal, stop as soon as
it is safe to do so and call an author-
ized HYUNDAI dealer for assistance.
DO NOT drive with your foot resting
on the brake pedal. Even light, butconstant pedal pressure can result in
the brakes overheating, brake wear,
and possibly even brake failure.
If a tire goes flat while you are driv-
ing, apply the brakes gently and
keep the vehicle pointed straight
ahead while you slow down. When
you are moving slowly enough for it
to be safe to do so, pull off the road
and stop in a safe location.
Keep your foot firmly on the brake
pedal when the vehicle is stopped to
prevent the vehicle from rolling for-
ward.
i
Whenever leaving the vehicle or
parking, always come to a com-
plete stop and continue to
depress the brake pedal. Shift
to the P (Park) position, then
apply the parking brake, and
place the POWER button in theOFF position.
Vehicles parked with the park- ing brake not applied or not
fully engaged may roll inadver-
tently and may cause injury to
the driver and others. ALWAYS
apply the parking brake before
exiting the vehicle.
WARNING
Always be ready to depress the
accelerator pedal when starting
off on a incline. The HAC acti-
vates only for approximately 5seconds.

Driving your vehicle
Always have your hands on the steering wheel while the LKA
system is activated. Also, when
Active LKA is selected from the
User Settings mode and if you
continue to drive with yourhands off the steering wheel
after the "Keep hands on steer-
ing wheel" warning message
appears, the system will stop
controlling the steering wheel.
However, if the driver has theirhands on the steering wheel
again, the system will start con-
trolling the steering wheel.
The steering wheel is not con-
tinuously controlled so if the
vehicle speed is at a higher
speed when leaving a lane the
vehicle may not be able to be
controlled by the system. The
driver must always follow thespeed limit when using thesystem.
The system detects lane lines
and controls the steering
wheel by a camera, therefore,
if the lane lines 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 LKA system.
You may not hear a warning sound of LKA system because
of excessive audio sound.
If any other warning sound
such as seat belt warning
chime is already generated,
the Lane Keeping Assist (LKA)
system warning may notsound.
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.
If you attach objects to the
steering wheel, the system
may not assist steering or the
hands off alarm may not work
properly. When you tow a trail-
er, make sure that you turn offthe LKA system.
When you tow a trailer, make
sure that you turn off the LKAsystem.

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.
6
Do not use water to extinguish a
fire when the vehicle power is
turned on. Serious electric
shock may result.
