My dad's 2010 s550 has been parked in the garage for about a month. He went on a trip overseas and so he hasn't turn it on for a while. Today he went to start it, but the engine wouldn't start. The car's lights and accessories mode (radio, interior lighting, etc.) work, but the engine fail to start. We are thinking about jump starting it with our Acura MDX. Do we connect the negative clamp onto this brown thing? Sorry it's not my car...so im not familiar lol. TIA.

jump starting these cars is not recommended. hook up a trickle charger.

so if i use charger..i would hook up clamps to same areas as i would if i was to jump start right? that brown thing (negative) and the positive on the battery.

jchen001

also..on the charger that i have...it asks for battery type. is 2010 S550 battery considered gel or agm? there's no vrla option

Jchen001,

Any chance you tried calling a MB Service Advisor? Or the parts department for an answer? When you find out, let us know too.

On a side note the Mercedes charger (CTEK brand) doesn't ask for the battery type when charging. What type of battery charger are you using ? (Out of curiosity..if you don't mind me asking)

jchen001

Never mind I got the issue resolved. Turns out the battery needed some charging so I left it over night to charge and then the next day the car started with no problems!

if you are in the US and the car is still under warranty, why not call

THE MERCEDES-BENZ 24-
HOUR ROADSIDE ASSISTANCE PROGRAM

if you are still within warranty, this should be free service

actually road side is for the life of the car here in the US.

I believe the roadside assistance has changed in the last few years. If you are out of warranty you have to spend a certain amount at an authorized Mercedes dealer on your car (yes it is per car, not driver) to enjoy roadside assistance.
