I am a new (and very happy) 02 Cambio Coupe owner and as I drive around, I'm coming up with questions. Searching this forum addressed my worry about my oil pressure gauge being pinned at the max of 70 during all ordinary driving, apparantly that's "normal." But here's what may be a stupid question that I couldn't find answered. My car beeps repeatedly whenever the driver's door is ajar, even without the key in the ignition and nothing obvious is left on or running. Is this also "normal"?
