Have Mercedes Questions? Ask a Mechanic for Answers ASAP
To open the trunk with the key you need to insert the key and turn it counterclockwise to the 10 o'clock position and hold it there then push in on the lock. Is that what you have tried?
yes that is what i tried, i also tried to pump it before i did it as well
Ok, there is also a positive jumper terminal under the hood just in front of the fuse box. You can attach a jumper cable there and use the remote or the trunk release switch in the car to open the trunk.
that wont work my battery is already off the cables in the trunk
It will still work
Just attach the positive to the terminal and the negative to the chassis.
Ok, do you know where the terminal is located?
not really im assuming infront of fuse box like you said
Just in front, under a cover with an X marked on it.
ok whats the chassis look like
The chassis is the body of the car. You attach your ground jumper cable to any metal point on the body of the car. You can also attach it to a metal bracket or bolt on the motor. You just want to be sure that it is a good ground and not something that is insulated in rubber.
give me a few minutes im going to go try your advice
X12/3 is the jumper terminal
in the picture above
i couldnt get it im just going to have it towed to mercedes thanks for your advice
You're quite welcome
