Description

Security Alarm System:

The security alarm system is an anti-theft alarm system. If someone tries to open the trunk, hood or either door without

the ignition key, or if the roof is not fully latched the security control unit senses a signal from the sensors and activates
relays to flash the headlights and sound the horn for about two minutes.ProCarManuals.com

Power Window Key-off Timer Operation:
The power windows can still be operated for about ten minutes after the ignition switch is turned from the "II" to the "I"
or "O" position as long as neither of the doors has been opened. This provides a convenience to parked occupants while
offering a degree of security against unwanted or accidental window operation.ProCarManuals.com
