Practical hints Fuses 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. Warning! If a newly inserted fuse blows again, have the cause determined and rectified by an authorized Mercedes-Benz Light Truck Center. A fuse chart explains the fuse allocation and fuse amperages. It is located in the cargo compartment with the vehicle tool kit ( page 469). The electrical fuses are located in different fuse boxes: on the passenger side of the engine compartment ( page 519) in the cargo compartment ( page 519) in the passenger compartment ( page 520) Before replacing fuses: Apply the parking brake ( page 65). Make sure automatic transmission is set to position P ( page 192). The gear position indicator in the multifunction display should be on P. Turn off all electrical consumers. Turn off the engine ( page 66). Remove the SmartKey from the starter switch. Vehicles with KEYLESS-GO*: Open the driver's door (this puts the starter switch to position 0, same as with the SmartKey removed from starter switch). The driver's door can then be closed again. G 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 Light Truck Center i A blown fuse must be replaced by an appropriate spare fuse (recognizable by its color or the fuse rating given on the fuse) of the amperage recommended in the fuse chart. Any Mercedes-Benz Light Truck Center will be glad to advise you on this subject. 518
