Immobilizer system (if equipped)
Your vehicle may be equipped with an
electronic engine immobilizer system to
reduce the risk of unauthorized vehicle
use.
Your immobilizer system is comprised of
a small transponder in the ignition key
and electronic devices inside the vehicle.
With the immobilizer system, whenever
you insert your ignition key into the igni-
tion switch and turn it to ON, it checks
and determines and verifies if the ignition
key is valid or not.
If the key is determined to be valid, the
engine will start.
If the key is determined to be invalid, the
engine will not start.To deactivate the immobilizer sys-
tem:
Insert the ignition key into the key cylin-
der and turn it to the ON position.
To activate the immobilizer system:
Turn the ignition key to the OFF position.
The immobilizer system activates auto-
matically. Without a valid ignition key for
your vehicle, the engine will not start.
WARNING
In order to prevent theft of your
vehicle, do not leave spare keys
anywhere in your vehicle. Your
Immobilizer password is a cus-
tomer unique password and should
be kept confidential. Do not leave
this number anywhere in your vehi-
cle.
WARNING - Ignition key
Leaving children unattended in a
vehicle with the ignition key is dan-
gerous even if the key is not in the
ignition switch. Children copy
adults and they could place the key
in the ignition switch. The ignition
key would enable children to oper-
ate power windows or other con-
trols, or even make the vehicle
move, which could result in serious
bodily injury or even death. Never
leave the keys in your vehicle with
unsupervised children.
WARNING
Use only KIA original parts for the
ignition key in your vehicle. If an
aftermarket key is used, the ignition
switch may not return to ON after
START. If this happens, the starter
will continue to operate causing
damage to the starter motor and
possible fire due to excessive cur-rent in the wiring.
