diagonally, since it could result in damage to the chassis alignment.

RNever try to free a vehicle that is still

coupled to a trailer.

RIf possible, a vehicle equipped with a trailer hitch receiver should be pulled backward in its own previously made tracks.

Fuses Introduction The electrical fuses in your vehicle serve to switch off malfunctioning power circuits. If a fuse is blown, the components and systems secured by that fuse will stop operating. G Warning! Only use fuses approved by Mercedes-Benz with the specified amperage for the system in question and do not attempt to repair or bridge a blown fuse. Using other than approved fuses or using repaired or bridged fuses may cause an overload leading to a fire, and/or cause damage to electrical components and/or systems. Have the cause determined and remedied by an authorized Mercedes-Benz Center.
