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 follo wing when pressing the ENGINE START/STOP button:
• Do not allow objects that emit strong radio waves near 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 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 tailgate, hood or doors are forcibly
opened. The alarm does not activate if the tailgate or doors are opened with the key,
remote transmitter or keyless access system.
However, the alarm activates if a door is op ened with the key and then the hood is
opened before the power mode is set to ON.
■When the security system alarm activates
The horn sounds intermittently, and some exterior lights flash.
■To deactivate the security system alarm
Unlock the vehicle using the key, remote tra nsmitter, or keyless access system. The
system, along with the horn and flashing lights, is deactivated.
