Checking operating fluids
Checking the coolant level
It is necessary to check the coolant level
to ensure that the engine does not over
heat.
>Important!
The cooling system is maintenance free
under normal operating conditions. A
drop in the coolant level indicates leak
age.
If you are losing coolant
 Top up the coolant.
 Have the reason for the loss of coolant
investigated by a qualified specialist
workshop, e.g. a smart center.
Checking the coolant level
쮿 Let the radiator cool down for at least
30 minutes.
쮿 Cover the cap for the coolant expansion
reservoir with a cloth before touching
it.
쮿 Turn the cap one complete revolution
in order to allow the excess pressure to
escape.
쮿 Unscrew the cap and remove it.
쮿 Look down into the reservoir for a vi
sual check.
> In the reservoir, there are two ridges
of different heights.
 The longer one (A) indicates the
maximum filling level.
 The shorter one (B) indicates the
minimum filling level.
Topping up the coolant
쮿 You should only top up the coolant as
far as the maximum filling level.
쮿 Replace the cap and tighten when fin
ished.
>Note!
Warm water expands, which is why it may
extend beyond the maximum filling level.
Danger of injury!
The cooling system is pres
surised. Therefore, only unscrew the
cap once the engine has cooled down.
Allow it to cool down for at least
30 minutes. You could otherwise be
scalded by escaping hot coolant.
