Engine immobilizer system

The vehicle's keys have built-in transponder chips that prevent
the engine from starting if a key has not been previously regis-
tered in the vehicle's on-board computer.
Never leave the keys inside the vehicle when you leave the vehi-
cle.
This system is designed to help prevent vehicle theft but does
not guarantee absolute security against all vehicle thefts.
The indicator light flashes after
the key has been removed from
the engine switch to indicate that
the system is operating.
The indicator light stops flashing
after the registered key has been
inserted into the engine switch to
indicate that the system has been
canceled.
