For safety and security
Immobilizer system
The indicator light flashes after
the power switch has been turned
off to indicate that the system is
operating.
The indicator light stops flashing
after the power switch has been
turned to ACCESSORY or ON

■System maintenance
The vehicle has a maintenance-free type immobilizer system.

●If the grip portion of the key is in contact with a metallic ob ject
● If the key is in close proximity to or touching a key registered to the security
system (key with a built-in transponder chip) of another vehicl e
The vehicle’s keys have built-in transponder chips that prevent
the hybrid system from starting if a key has not been previousl y
registered in the vehic le’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.
