Have BMW 325i can you jump start without causing trouble?

You can jump the BMW 325i however there are some precautions listed in the Bentley manual. While hooking up the jumper cables hook up the positive one to the battery or the power box ( engine compartment passenger side-all those black cables ) and the negative one to the body of your car ( not the negative post ). The manual also says to turn on your blower motor and headlights before trying to start the car.
