WARNING
THIS PRODUCT CONTAINS A BUTTON
BATTERY.
If swallowed, a lithium button battery
can cause severe or fatal injuries within
2 hours. Keep batteries out of reach of
children.
If you think batteries may have been
swallowed or placed inside any part
of the body, seek immediate medical
attention.
Information
An inappropriately disposed
battery can be harmful to
the environment and human
health. Dispose of the battery
according to your local law(s) or
regulations.
Immobilizer System (if
equipped)
The immobilizer system helps protect
your vehicle from theft. If an improperly
coded key (or other device) is used, the
engine’s fuel system is disabled.
When the Engine Start/Stop button
is pressed to the ON position, the
immobilizer system indicator should
come on briefly, then go off. If the
indicator starts to blink, the system does
not recognize the coding of the key.
Place the ignition switch to the LOCK/
OFF position, then place the ignition
switch to the ON position again.
The system may not recognize your
key’s coding if another immobilizer
key or other metal object (for example,
key chain) is near the key. The engine
may not start because the metal may
interrupt the transponder signal from
transmitting normally.
If the system repeatedly does not
recognize the coding of the key, it is
recommended that you contact your
HYUNDAI dealer.
Do not attempt to alter this system
or add other devices to it. Electrical
problems could result that may make
your vehicle inoperable.

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.
