Checking and replacing fuses

To prevent short-circuits and overloading of the electrical system, the individual circuits are protected by fuses. One fuse box can be found at the right-hand side of the trunk in direction of travel. Two additional fuse boxes are located at the outer ends of the dashboard on the driver's and passenger's side.

The plastic gripper and spare fuses can be found in both fuse box covers at the outer ends of the dashboard on the driver's and passenger's side.

Information
Spare fuses in the fuse box covers:

  1. Driver’s side: 7.5A and 10 A
  2. Passenger’s side: 20 A and 25 A .

  1. If possible, switch off the load with the defective fuse.
  2. Open the fuse box cover.
  3. Remove the fuse from its slot using the yellow plastic gripper D (Fig. 67) in order to check it.
    A blown fuse can be identified by the melted metal strip.
  4. Insert a new fuse. The replacement fuse must have the same rated current as the one it is replacing.

Information
If the same fuse blows repeatedly, the cause must be rectified immediately.
