Immobilizer system
The immobilizer system protects your
vehicle from theft. If an improperly
coded key (or other device) is used, the
engine’s fuel system is disabled.
When the ignition switch is placed in
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 (i.e., 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.

important part of the immobilizer
system. It is designed to give years

Convenient features
Electric power steering (EPS)
The system assists you with steering
the vehicle. If the engine is off or if
the power steering system becomes
inoperative, the vehicle may still be
steered, but it will require increased
steering effort.
Also, the steering effort becomes
heavier as the vehicle’s speed increases
and becomes lighter as the vehicle’s
speed decreases for better control of the
steering wheel.
Should you notice any change in the
effort required to steer during normal
vehicle operation, we recommend that
the system be checked by an authorized
HYUNDAI dealer.
NOTICE
If the Electric Power Steering System
does not operate normally, the
warning light (
) will illuminate on
the instrument cluster. The steering
wheel may become difficult to control
or operate. Take your vehicle to an
authorized HYUNDAI dealer and
have the system checked as soon as
possible.
i Information
The following symptoms may occur
during normal vehicle operation:
• The steering effort may be high
immediately after placing the ignition
switch in the ON position.
This happens as the system performs
the EPS 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
EPS relay after the ignition switch
is placed to the ON or LOCK/OFF
position.
• Motor noise may be heard when the
vehicle is at stop or at a low driving
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.
WARNING
Never adjust the steering wheel while
driving. You may lose steering control
and cause severe personal injury, death
or accidents.
