STEERING WHEEL
Motor-Driven Power Steering
(MDPS)
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 retailer of
Genesis Branded products.
If the Motor-Driven Power Steering
(MDPS) System does not operate
normally, the warning light ( )
will illuminate on the instrument
cluster. You may steer the vehicle,
but it will require increased steer-
ing efforts. Take your vehicle to an
authorized retailer of Genesis
Branded products and have the
system checked as soon as possi-
ble.
Information
The following symptoms may occur
during normal vehicle operation:
• The steering effort may be high
immediately after the Engine
Start/Stop button is in the ON posi-
tion.
This happens as the system per-
forms the MDPS system diagnostics.
When the diagnostics is completed,
the steering wheel 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 driv-
ing speed.
• When you operate the steering
wheel in low temperatures, abnor-
mal noise may occur. If the temper-
ature rises, the noise will disappear.
This is a normal condition.
