Convenience Features

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, you have the system
checked by an authorized HYUNDAI
dealer.
CAUTION
If Electric Power Steering does not
operate normally, the
warning light
and the message ‘Check motor driven
power steering’ will illuminate on the
instrument cluster. You may steer the
vehicle, but it will require increased
steering efforts. We recommend that
you take the 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 pressing the Engine Start/Stop button to the ON position. This happens as the system performs
the EPS system diagnostics. When the
diagnostics are completed, the steering
wheel effort will return to its normal condition.

[ When the battery voltage is low, you
might have to put more steering effort.
However, it is a temporary condition so
that it will return to normal condition
after charging the battery.

[ A click noise may be heard from the
EPS relay after the Engine Start/Stop
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 temperatures, abnormal noise
may occur. If the temperature rises, the
noise will disappear. This is a normal condition.

[ When an error is detected from EPS, the steering effort assist function will
not be activated in order to prevent
fatal accidents. Instrument cluster
warning lights may be on or the steering effort may be high. If these
symptoms occur, drive the vehicle to a
safe area as soon as it is safe to do so.
You have the system checked by an
authorized HYUNDAI dealer as soon as possible.
