Transmission Fluid

It’s worth noting that, once again, smart do not give a specific service distand or time for replacing the gear box fluid. In the original model smart, they claimed it would never require changing.

That was obviously bullshit and should be ignored.

I would say to replace the transmission fluid every 60,000 miles. Transmission fluid specs can be found here.

Timing Chain

Smart don’t give a chain change schedule. Generally you just fit a new chain when the old one is loose and rattles as the engine is running. Chains “stretch” instead of snap like belts so you have a gradual degradation instead of a sudden failure.

453 Electric Drive (EQ)

Smart royally screw over electric drive owners when it comes to servicing. Considering there’s no oil, oil filter, air filter, spark plugs, V-belt or valve adjustment to be changed, they actually charge more to service an electric drive than they do to service a standard petrol model. Originally smart stated that electric drive servicing would be cheap at under £100 but…

…I was quoted £270 for a single service. If you buy the smart service plan you can bring that down to £156 per service in the UK. US and Canada can work out to be cheaper. I guess that smart dealers weren’t interested in earning less money so decided to take the piss.

Own Or Rent The Battery?

If you own the battery, great. You can do whatever you want. Service the car yourself.

If you are still renting the battery, check your documentation for the rental agreement as there is a chance that they have screwed you in the small print and will insist that you have it serviced at smart. If you don’t, the warranty on your HV battery may be affected.

If you are renting, consider contacting smart to see if you can buy it outright. The full purchase option was announced in 2017 and gives you a set guarantee for the battery.

You can do all of this yourself with the exception of the HV battery check. If you have MB Star Diagnostics, you can do this test easily. The only thing you can’t do is perform any updates to the software that smart might have.
