Fuses near the vehicle battery

How to get to it

Additional fuses are located near the vehicle battery.

Our source doesn’t describe how to open this fuse box. Check your owner’s handbook.

Find it by its handbook number

Vauxhall’s handbook lists these as fuses near the vehicle battery, separate from the fuse boxes. Its picture of them doesn’t give enough positional detail for a trustworthy map, so we don’t draw one.

Use the fuse numbers and the picture of this area in your owner’s manual to identify each fuse, and check it against the handbook before removing anything.
