320 Fuses As soon as the vehicle has been loaded: X Prevent the vehicle from rolling away by applying the parking brake. X Shift the automatic transmission to position P. X Turn the SmartKey to position 0 in the ignition lock and remove the SmartKey. X Secure the vehicle. Never attempt to recover a stuck vehicle with a trailer attached. Pull out the vehicle backwards, if possible using the tracks it made when it became stuck. Fuses Important safety guidelines The fuses in your vehicle serve to close down faulty circuits. If a fuse blows, all the components on the circuit and their functions will fail. ! Only lash the vehicle down by the wheels or wheel rims, not by parts of the vehicle such as axle or steering components. Otherwise, the vehicle could be damaged. Roadside assistance Notes on 4MATIC vehicles ! Vehicles with 4MATIC must not be towed with either the front or the rear axle raised, as doing so will damage the transmission. If the vehicle's transmission, front, or rear axle is damaged, have the vehicle transported on a truck or trailer. In the event of damage to the electrical system If the battery is defective, the automatic transmission will be locked in position P. To shift the automatic transmission to position N, you must provide power to the vehicle's electrical system in the same way as when jump-starting (Y page 315). Have the vehicle transported on a transporter or trailer. 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. Blown fuses must be replaced with fuses of the same rating, which you can recognize by the color and value. The fuse ratings are listed in the fuse allocation chart. An authorized Mercedes-Benz Center will be happy to advise you. Recovering a vehicle that has become stuck ! Pull away smoothly, slowly, and in a straight line when pulling out a vehicle that has become stuck. Excessive tractive power could damage the vehicles. If the drive wheels have become stuck in loose or muddy ground, pull the vehicle out with extreme caution, particularly if it is laden. i If a fuse has blown, visit a breakdown service or an authorized Mercedes-Benz Center. If the newly inserted fuse also blows, have the cause traced and rectified at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center. ! Only use fuses that have been approved for Mercedes-Benz vehicles and which have the correct fuse rating for the system concerned. Otherwise, components or systems could be damaged.
