SECURILOCK ி PASSIVE ANTI-THEFT SYSTEM
The SecuriLock
௢ passive anti-theft system provides

vehicle’s engine can only be started with the two
special SecuriLock
௢ electronically coded keys
provided with your vehicle. Each time you start your
vehicle, the SecuriLock
௢ key is read by the
SecuriLock
௢ passive anti-theft system. If the
SecuriLock
௢ key identification code matches the
code stored in the SecuriLock
௢ anti-theft system,
the vehicle’s engine is allowed to start. If the
SecuriLock
௢ key identification code does not match
the code stored in the system or if a SecuriLock

vehicle’s engine will not operate.
The SecuriLock
௢ passive anti-theft system is not
compatible with aftermarket remote start systems.

SecuriLock
௢ key may cause vehicle starting
