I want to jump start my Benz 420
I can't open trunk without power The manual trunk release is not working. Can I jump start fromunder the hood?
I didn't know you could jump start the car from the trunk! lol
If you have your key, you can unlock/open the trunk using it. Put the key in and turn it to the left. This will unlock the trunk (I had to do this when my central locking pump failed and none of the automatic releases were working).
The battery is located in the trunk on the right hand side.
1- open the front hood 2- on the driver side of the hood in front of the fuse box there is a little box with an X on it, open it, (it has clips on the side of the cover) that's the possitive from the battery, hook up the positive jumper wire to it 3- hook up ground wire anywhere on the frame of the car 4- turn the car on!
