Description

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
