Electric Power Steering (EPS)
The system assists you with steering
the vehicle. If the vehicle is turned off
or if the power steering system
becomes inoperative, you may still
steer the vehicle, but it will require
increased steering effort.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the system
checked by an authorized HYUNDAI
dealer.Information
The following symptoms may occur
during normal vehicle operation:
 The steering effort may be high immediately after placing the
POWER button in the ON position.
This happens as the system performs
the EPS system diagnostics. When
the diagnostics is completed, the
steering wheel will return to its nor-
mal condition.
 A click noise may be heard from the EPS relay after the POWER button
is in the ON or OFF position.
 Motor noise may be heard when the vehicle is at a stop or at a low driving
speed.
 When you operate the steering wheel in low temperature, abnormal noise
may occur. If temperature rises, the
noise will disappear. This is a normal
condition.  When an error is detected from the
EPS, the assistant function of steer-
ing effort will not be activated in
order to prevent fatal accidents.
Instrument cluster warning lights
may be on or the steering effort may
be high. When the following symp-
toms occur, immediately drive the
vehicle to a safe area and check it.

Convenient features of your vehicle
If the Electric Power Steering System does not operate nor-
mally, the warning light ( ) willilluminate on the instrument
cluster. You may steer the vehi-
cle, but it will require increased
steering efforts. Take your vehi-
cle to an authorized HYUNDAI
dealer and have the system
checked as soon as possible.

43. Is there a risk of electric shock from the high-voltage parts in the event of a colli- sion or accident?
The FCEV is designed to detect impact events during a collision or
accident so that the hydrogen gas supply is immediately cutoff. Also,
the high-voltage relay is activated to cutoff the supply of electric power
to the fuel cell stack and high-voltage battery. Moreover, the FCEV
satisfies international electrical safety standards for collisions and
accidents.
44. Should I take any special safety precau-tions in the event of a collision or acci- dent?
Despite the uniqueness of the hydrogen FCEV, you do not have to
take any special safety precautions in the event of a minor collision or
accident. In the event of a minor accident, turn off the vehicle to cutoff
the supply of electric power and hydrogen gas. Also, the FCEV is
equipped with collision sensors at the front and rear of the vehicle so
those sensors are activated during an actual collision to automatically
cutoff the supply of power and hydrogen to ensure driver and passen-
ger safety. For other situations, follow the same procedures as you
would with a standard vehicle. Depending on the severity of the colli-
sion or accident, take appropriate measures.
45. Is a high-voltage battery designed toensure occupant safety? Can it explode from a collision?Our battery packs are designed to prevent any explosion due to
physical impact or damage, and they fully satisfy international safety
standards.
