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 Center. The following aids are available to help you replace fuses: Fuse chart The fuse chart is located in the fuse box in the passenger compartment ( page 429). The fuse chart explains the fuse allocation and fuse amperages. Spare fuses Spare fuses are located in the vehicle tool kit in the trunk ( page 393). Fuse extractor The fuse extractor is located in the vehicle tool kit in the trunk ( page 393). The electrical fuses are located in different fuse boxes: Main fuse box in passenger compartment ( page 429) Fuse box in trunk ( page 429) Before replacing fuses: Apply the parking brake ( page 59). Make sure the gear selector lever is set to position P ( page 171). Turn off all electrical consumers. Turn off the engine ( page 60). Remove the SmartKey from the starter switch. Vehicles with KEYLESS-GO*: Open the driver's door. 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 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 Center will be glad to advise you on this subject. 428
