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.

opened. The alarm does not activate if the trunk or doors are opened with the key,
