Practical hints Fuses The electrical fuses in your vehicle serve to switch off malfunctioning power circuits. If a fuse is blown, the component(s) and systems secured by that fuse will stop operating. Warning! ! Switch off the vehicle's internal electrical functions ( page 448) when you are working on the fuses. If a newly inserted fuse blows again, have the cause determined and rectified at an authorized Mercedes-Benz Center. A fuse chart explains the fuse allocation and fuse amperages. It is located in the main fuse box in the passenger compartment ( page 457). Before replacing fuses: Depress the parking brake ( page 134). Make sure the manual transmission is in Neutral ( page 136), automatic transmission* is set to P ( page 140). The gear position indicator in the tachometer display should be on P. Turn off all electrical consumers. Turn off the engine ( page 134). Remove the SmartKey from the starter switch. Vehicles with KEYLESS-GO* (Canada only): 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 at an authorized Mercedes-Benz Center. i In case of a blown fuse contact Roadside Assistance or an authorized Mercedes-Benz Center. The electrical fuses are located in different fuse boxes: Fuse box in passenger compartment ( page 457) Fuse box in engine compartment ( page 457) Fuse box in trunk ( page 458) 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. 456
