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
mode to indicate that the system
has been canceled.
■System maintenance
The vehicle has a maintenance-free type 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 registered 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 hybrid system from starting if a key has not been previously
registered 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.

■Canceling and automatic re-enabling of the intrusion sensor
●The alarm will still be set even when the intrusion sensor are canceled.
● After the intrusion sensor are canc eled, pressing the power switch or
unlocking the doors using the entry function or wireless remote control will
re-enable the intrusion sensor.
● The intrusion sensor will automatically be re-enabled when the alarm sys-
tem is deactivated.
■ Intrusion sensor detection considerations
The sensor may trigger the alar m in the following situations:
● Places with extreme vibrations or noises, or situations in which the vehicle is
subject to repeated impacts or vibrations:
• When parked in a parking garage
• When the vehicle is transported by a ferry, trailer, train, etc.
• When ice adhering to the vehicle is removed
• When the vehicle is in an automatic or high-pressure car wash
• When in a hail or lightning storm
●
A window is open.
In this case, the sensor may detect the
following:
• Wind or the movement of objects
such as leaves and insects inside the
vehicle
• Ultrasonic waves emitted from devices such as the intrusion sensors
of other vehicles
• The movement of people outside the vehicle
● Unstable items, such as dangling acces-
sories or clothes hanging on the coat
hooks, are in the vehicle.
