Electric Power Steering (EPS)
The system assists you with steering
the vehicle. If the engine 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.If the Electric Power Steering
System does not operate normal-
ly, the warning light ( ) will illu-
minate on the instrument cluster.
You may steer the vehicle, but it
will require increased steering
efforts. Take your vehicle to an
authorized 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 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
in the ON or OFF position.
• Motor noise may be heard when the
vehicle is at a stop or at a low driv-
ing speed.
• If the outside ambient temperature
is low, when you operate the steer-
ing wheel a noise from the electric
power steering may occur. As the
temperature increases, the noise will
dissappear. This is a normal condi-
tion.
