General notes

Notes on fuses and relays

WARNING Risk of accident and injury due to overloaded lines

If you manipulate or bridge a faulty fuse or if you replace it with a fuse with a higher amperage, the electric line could be overloaded.

This could result in a fire.

Always replace faulty fuses with speci‐ fied new fuses containing the correct amperage.

NOTE Damage or malfunctions caused by moisture

Moisture may cause damage to the electrical system or cause it to malfunction.

When the fuse box is open, make sure that no moisture can enter the fuse box.
When closing the fuse box, make sure that the seal of the lid is positioned cor‐ rectly on the fuse box.

The electrical fuses in your vehicle switch off defective circuits. If a fuse blows, all the components on the circuit and their functions will cease to operate.

Replace faulty fuses with fuses of the same type that have the fuse rating recommended in the following overviews. Fuses of the same type can be recognized by the color and fuse rating. A quali‐ fied specialist workshop will be happy to advise you.

If a new fuse blows again, have the cause determined and rectified at a qualified specialist work‐ shop.

The fuses and relays are split between the following fuse boxes in the vehicle:

Fuse box in the engine compartment (PDC‑E)
Fuse box in the co-driver footwell (PDC‑P)
Fuse box in the co-driver footwell on the A-pil‐ lar (PDC‑F)
Fuse box in the rear compartment (PDC‑R)
Pre-fuse box next to the starter battery in the seat base of the right-hand front seat

Always have the fuses in the pre-fuse box and the relays in the fuse boxes replaced at a qualified specialist workshop.

Preparing to replace a fuse

Apply the parking brake.
Vehicles with automatic transmission: shift the transmission to position .
Vehicles with manual transmission: shift to neutral.
Switch off all electrical consumers.
Remove the key from the ignition lock
