Electric power steering (EPS)
The system assists you with steering
the vehicle. If the engine is off or if
the power steering system becomes
inoperative, the vehicle may still be
steered, but it will require increased
steering effort.
Also, the steering effort becomes
heavier as the vehicle’s speed
increases and becomes lighter as
the vehicle’s speed decreases for
better control of the steering wheel.
Should you notice any change in the
effort required to steer during normal
vehicle operation, we recommend
that the system be checked by an
authorised HYUNDAI dealer.If the Electric Power Steering
(EPS) System does not operate
normally, the warning light ( )
will illuminate on the instrument
cluster. The steering wheel may
become difficult to control or
operate. Take your vehicle to an
authorised HYUNDAI dealer and
have the system checked as soon
as possible.
Information
The following symptoms may occur
during normal vehicle operation:
• The steering effort may be high
immediately after placing the igni-
tion switch or the Engine Start/Stop
button in the ON position.
This happens as the system per-
forms the EPS system diagnostics.
When the diagnostics are complet-
ed, the steering wheel will return to
its normal condition.• A click noise may be heard from the
EPS relay after the ignition switch is
placed to the ON or LOCK/OFF
position (Without Smart key sys-
tem).
A click noise may be heard from the
EPS relay after the Engine
Start/Stop button is placed in the
ON or OFF position. (With Smart
key system)
• Motor noise may be heard when the
vehicle is at a stop or at a low driv-
ing speed.
• When you operate the steering
wheel in low temperatures, the
steering effort may be high and
abnormal noise may occur. If the
temperature rises, the noise will dis-
appear. This is a normal condition.
• When the vehicle is stationary, if
you turn the steering wheel all the
way to the left or right continuously,
the steering wheel effort increases.
This is not a system malfunction. As
time passes, the steering wheel
effort will return to its normal con-
dition.

NOTICE
Fuse replacement
Never replace a fuse with any-
thing but another fuse of the
same rating.
A higher capacity fuse could
cause damage and possibly a
fire.
Never install a wire or alumini-
um foil instead of the proper
fuse - even as a temporary
repair. It may cause extensive
wiring damage and a possible
fire.
WARNING
Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage the
system.
CAUTION
When replacing a blown fuse
or relay with a new one, make
sure the new fuse or relay fits
tightly into the clips. The
incomplete fastening fuse or
relay may cause the vehicle
wiring and electric systems
damage and a possible fire.
Do not remove fuses, relays
and terminals fastened with
bolts or nuts. The fuses,
relays and terminals may be
fastened incompletely, and it
may cause a possible fire. If
fuses, relays and terminals
fastened with bolts or nuts are
blown, we recommend that
you consult an authorised
HYUNDAI dealer.
Do not input any other objects
except fuses or relays into
fuse/relay terminals such as a
driver or wiring. It may cause
contact failure and system
malfunction.
CAUTION
