erly, try replacing the battery with a

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 protects
your vehicle from theft. If an improp-
erly coded key (or other device) is
used, the engine's fuel system is dis-
abled.
When the ignition switch is placed in
the ON position, the immobilizer sys-
tem 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 remote key
or smart key if another remote key or
smart key device is nearby or a metal
object such as a key chain is causing
interference with the remote key or
smart key.
If this occurs, your vehicle may not
start. Remove any metal objects or
additional keys near the remote key
or smart key before attempting to
start the vehicle again.
