KEYS
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. Children copy adults and
they could place the key in the igni-
tion. The ignition key would enable
children to operate power windows
or other controls, 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.
CAUTION
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.

Knowing your vehicle8 3Your vehicle is equipped with an elec-
tronic 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 antenna coil in the key cylinder and
ICU (Immobilizer Control Unit) in the
steering shaft.
With this system, whenever you insert
your ignition key into the ignition switch
and turn it to ON, the antenna coil in the
ignition switch receives a signal from the
transponder in the ignition key and then
sends the signal to the ECU (Engine
Control Unit).
The ECU checks the signal whether the
ignition key is valid.
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
system:Insert the ignition key into the key cylin-
der and turn it to the ON position.
To activate the immobilizer sys-
tem: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.✽ ✽
NOTICEWhen starting the engine, do not use the
key with other immobilizer keys around.
Otherwise the engine may not start or
may stop soon after it starts. Keep keys
separate to avoid immobilizer malfunc-
tions.
Limp home (override) procedureWhen you turn the ignition key to the ON
position, if the IMMO indicator goes off
after blinking 5 times, your transponder
equipped in the ignition key is out of order.
You cannot start the engine without the
lime home procedure. To start the engine,
you have to input your password by using
the ignition switch.
The following procedure is how to input
your password of “2345” as an example.
1. Turn the ignition key to the ON position.
The IMMO indicator ( ) will blink 5
times and go off indicating the begin-
ning of the limp home procedure.
2. Turn the ignition key to the ACC posi-
tion.
IMMOBILIZER SYSTEM (IF EQUIPPED)
CAUTION
Do not put metal accessories near
the key or ignition switch.
The engine may not start for the
metal accessories may interrupt the
transponder signal from normally
transmitting.
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.
