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.
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 is completed,
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.
• 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.
i
If the Electric Power Steering
System does not operate nor-
mally, the warning light ( ) will
illuminate 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.
