As Mr. Meehan suggests, the Owner's Manual probably has directions for jump starting the vehicle, including a very clear graphic showing the location of the hookups located under the hood.

And, if the manual doesn't have this particular information, all I can say is shame on GM for omitting this vital bit of information. That, however does not change my belief that perhaps 99% of a car owner's everyday questions about his car can be resolved by using the Owner's Manual. However, this clearly does not apply in this case--to GM's discredit.
I'm sorry, but I just have to ask this question:
What exactly do people think is contained in a car Owner's Manual?
I don't mind answering questions with an obvious answer, but the fact remains that 99% of these questions can be answered simply by opening the glove compartment and spending perhaps 3 minutes perusing the manual. If you are stuck on the side of the highway, opening the glove compartment is certainly more convenient than trying to access the internet and then waiting for a response. Even if you are at home, if you have a question about something on your car, wouldn't it be easier and quicker to first take a look at the Owner's Manual than to post a question that might not get a useful response for several hours?
A few months ago, one poster responded negatively to my suggestion of learning to consult her manual by stating something along the lines of, "it is written so that only an engineer can understand it". In reality, these booklets are written on an 8th grade reading level, and are designed for the non-motorhead.
Yes, you do have to slog through perhaps 20 pages on how to wear a seat belt, but then you encounter information such as--how to change most of the light bulbs in the car, what that mysterious little unlabeled switch on the dashboard actually does, how to program the security system and the audio system, which tire rotation pattern to use, which type of transmission fluid to use, whether tire chains can be used on that vehicle, how to properly maintain the vehicle, etc., etc., ad infinitum.
So, once again I have to ask--Since most car owners don't ever take the time to look at it, what do these non-readers think is contained in that book?
