801-2. Theft deterrent system
GS350_250_OM_OM30E16E_(EE)
Engine immobilizer system
The indicator light flashes after the
engine switch has been turned off to
indicate that the system is operating.
The indicator light stops flashing
after the engine switch has been
turned to ACCESSORY or IGNI-
TION ON mode to indicate that the
system has been canceled.
■System maintenance
The vehicle has a maintenance-free type engine immobilizer system.
■Conditions that may cause the system to malfunction
●If the grip portion of the key is in contact with a metallic object
●If the key is in close proximity to or touching a key to the security system (key with a
built-in transponder chip) of another vehicle
The vehicle’s keys have built-in transponder chips that prevent the
engine from starting if a key has not been previously registered in the
vehicle’s on-board computer.
Never leave the keys inside the ve hicle when you leave the vehicle.
This system is designed to help prevent vehicle theft but does not guar-
antee absolute security against all vehicle thefts.
