The smart standard batteries can start giving up after 3 years so get a new one before it dies.
Battery Removal – 451
Unlike the previous fortwo, the 451 has a slightly larger battery to deal with increased electrics or the MHD system. The problem with a physically larger battery is that the space is a bit tight for removal. Go over to the passenger side... ...and pull back the...
Battery Removal – Roadster
The battery fitted at the factory is usually a 3 star unit meaning it is guaranteed for 3 years. They often last longer, especially if you look after it.
Battery Trickle Charger
If you don't use your smart that often, it's a good idea to keep the battery charged.
Batteries can be managed and topped up using a trickle charger.

Becker Navigation Sound Aux Input
I was contacted by Derfalk from the smart-roadster-board.ch about his mod to the Navigation & Sound. This particular stereo is a re-faced Becker BE6040 that was used in other Mercedes models. There isn't an option for an auxiliary input on the back of the stereo...

Bosch Highline Decoding
Ok, so you have a Bosch Highline stereo but don't know the security code. It's not a surprise because the security code can be changed by the user so it's rarely written down. Before you do anything, try the code 0000. That's the code from the factory and many people...
Bosch Highline Maps
Bosch Highline Map Updates This is the Bosch Highline stereo as fitted to many smart fortwo 451s from early 2010 to 2014. I have covered how much of a piece of crap it is on other pages but this will add to that. Good News Or Bad News First? Err, let's go for the good...
Bosch Injector Servicing
The smart 450 fortwo petrol and Roadster uses Bosch EV6 injectors and like all injectors, they eventually require cleaning. The injectors have replaceable filters that catch anything that the fuel filter lets passed. If you are removing your injectors to clean and...

Brabus 450 Side Spats
