How do you top up the coolant in a Smart car?

Model: Smart Smart 451 - Years 2007-2015
Part: Antifreeze coolant

How do you top up the coolant on a Smart? Engineers have hidden the coolant opening. It is usually found behind the front bumper or under an engine compartment, but here it is not immediately visible as in traditional cars. We access the engine compartment and locate the transparent tank, with a black/yellow cap and colored liquid. Be careful not to confuse it with the windshield washer tank! With the engine cold, the coolant level should be between "min" and "max". The cap must be opened only with the engine cold, we add the coolant and then close the cap. We may need a funnel, it will help us in the operation.
