Convenience Features5-40
Motor Driven Power Steering
(MDPS)
The Motor Driven Power Steering (MDPS)
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.
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. 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 MDPS 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
MDPS 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 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 condition.
• When an error is detected from MDPS,
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. Have the system checked by an
authorized HYUNDAI dealer as soon
as possible.
