The security system helps to protect
your vehicle and valuables from
theft. The horn sounds and a
combination of headlights, position
lights, side marker lights and

resets. To deactivate the system
before the two minutes have elapsed,
unlock the driver's door with the key
or the remote transmitter.
The security system automatically
sets 15 seconds after you lock the
doors, hood, and tailgate. For the
system to activate, you must lock the
doors from the outside with the key,
or use driver's lock tab, door lock

The security system indicator on the
instrument panel starts blinking
immediately to show you the system
is setting itself.
Once the security system sets,
opening any door, tailgate, or hood
without using the key or the remote
transmitter, will cause the alarm to
activate. It also activates if the
ignition switch is turned to the ON
(II) position, the audio unit is
removed from the dashboard or the
wiring is cut.The security system does not set if
