Checking the coolant level
Slowly turn cap 1 half a turn anti-clockwise and allow excess pressure to escape. Turn cap 1 further anti-clockwise and remove it. There is sufficient coolant in expansion tank 2 if the coolant is level with marker bar 3 in the filler neck when cold or approximately 1.5 cm higher when warm. If necessary, top up with coolant that has been tested and approved by Mercedes-Benz.
