When I start my car, my at oil temp light comes on for a brief amount of time (probably two seconds) along with the AWD light, doesn't flash and then immediately turns off. It turns off simultaneously with the AWD light. It doesn't come on while I am driving and It doesn't flash. It doesn't mention what to do about this in the manual and I am wondering if I should be worried. My transmission doesn't shake. I haven't had any problems driving. Should I get this checked out?
