I discovered recently how important it is to keep the fuse box on a car clean and the fuses in good condition. The MB cars have a round flat tool case good for the Benz car arrangement, but for the smart it would need to be fastened some how. Either way, Mercedes always includes fuses in a plastic box with fuse installer/puller.

What kind of fuses -- even relays- are good to have handy for a smart?

Volvos use several amperages of fuse and a paperclip to jump the fuel relay.

What would smart want/need/use?

The fuses listed in the owners manual would be a good place to start.....

If you had to pick, say, 5, which would you choose? And what about relays/bulbs?

I wouldn't bother since I've never had a problem with either on three 451s over 11 years. Just pick the most common fuses if you want to. ?

Most of the fuses are ATM, with a few main fuses being ATC.

I recommend buying the BUSSMANN ATMIDSK on Rock Auto.
Has six each of 5, 10, 15, 20, 25, and 30 amp light up fuses..
All the way at the bottom of the fuses...

The ATM fuses are here...

BUSSMANN ATCIDSK Fuse | RockAuto

RockAuto ships auto parts and body parts from over 300 manufacturers to customers' doors worldwide, all at warehouse prices. Easy to use parts catalog.

But this is overkill.
There are only a few ATC fuses, so you are better off buying them individually..

The 40 amp ATC fuse can be hard to find...

The 7 and 1/2 ATM and ATC can be found easily...

Blade Fuses

<p>Automotive blade fuses are the industry standard - used in most domestic and imported cars today. All Bussmann series blade fuses meet or exceed OEM and SAE standards. The easyID indicating blade fuses use LED technology making it easier to spot blown fuses in panels tucked in dark locations.</p>
