Dead battery in 745i after week long trip, and despite all the stellar advice in this forum to flip the switch in the trunk to prevent battery discharge, of course I didn’t do that! So here is the issue: given the spot where I parked in advance of the trip, the hood cannot be opened high enough to allow access to the jump start terminals. My question is whether it is safe to connect directly to the batter to jump the car, and if so, do you connect just the positive connection? The manual on page 208 does not indicate anything about doing that, but it also does not say NOT to do it. Has anyone done it before?
