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.
Turn the ignition switch to the LOCK/OFF
position, then turn the ignition switch to
the ON position again.
In some circumstances, the vehicle may
not recognize your smart key if another
smart key device is nearby or a metal
object such as a key chain is causing
interference with the smart key.
If this occurs, your vehicle may not
start. Remove any metal objects or
additional keys near the smart key before
attempting to start the vehicle again.
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. WARNING
In order to prevent theft of your
vehicle, do not leave spare keys
anywhere in your vehicle. Your
immobilizer password is a customer
unique password and should be kept
confidential.
NOTICE
The transponder in your key is an
important part of the immobilizer
system. It is designed to give years
of trouble-free service, however you
should avoid exposure to moisture,
static electricity and rough handling.
Immobilizer system malfunction could
occur.
Information
This device complies with Part 15 of the
FCC rules.
Operation is subject to the following three
conditions:
1.
This device may not cause harmful
interference.
2.
This device must accept any
interference r

eceived, including
interference that may cause undesired
operation.
3.
Changes or modifications not expr

essly
approved by the party responsible
for compliance could void the user’s
authority to operate the device
