Security System
Immobilizer System
The immobilizer system prevents a key that has not been pre-registered from
starting the engine. Each key contains electronic transmitters that use electronic
signals to verify the key.
Pay attention to the following when insert ing the key into the ignition switch or
pressing the ENGINE START/STOP button:
• Do not allow objects that emit strong ra dio waves near the ignition switch or the
ENGINE START/STOP button.
• Make sure the key is not covered by or touching a metal object.
• Do not bring a key from another vehicle’s immobilizer system near the ignition
switch or the ENGINE START/STOP button.
• Do not put the key near magnetic items. Electronic devices, such as televisions
and audio systems emit strong magnetic fields. Note that even a key chain can
become magnetic.
Security System Alarm
The security system alarm activates when the trunk, hood or doors are forcibly
opened. The alarm does not activate if the trunk or doors are opened with the key,
remote transmitter or smart entry system
*.
However, the alarm activates if a door is opened with the key and then the
transmission is taken out of
(P or the hood is opened before the ignition switch is
turned to ON
(w*1.
*1: Models with the smart entry system have an ENGINE START/STOP button instead of an
