Immobilizer system
The vehicle’s keys have
built-in transponder chips
that prevent the hybrid sys-
tem from starting if a key
has not been previously
registered in the vehicle’s
on-board computer.

the vehicle when you leave
the vehicle.
This system is designed to
help prevent vehicle theft

• The electronic key has been left in an area of approximately 6 ft. (2
m) of the outside of the vehicle for
10 minutes or longer.
• The smart key system has not been used for 5 days or longer.
