Check whether the blown fuse is a standard or a mini blade fuse (mini ones are roughly half the size), then choose the matching kit:

The handbook doesn't say which fuse rating or size is fitted - match the rating printed on the blown fuse. If it's a glass or ceramic cartridge fuse rather than a blade, these kits won't fit.
