sorry for dumb post. My Aunt is ill, and I have been driving her to Dr. in her 2005 Malibu (she can't climb up into my Silverado). When I set the anti-theft system, the alarm indicator light stays on for about 10 seconds, and then flashed every 10 seconds. Is this how the system is designed to operate?She lost her manual, which I need to replace.
thanks
