Top up the coolant if the level is below the MIN mark.
Adding coolant
Remove left cover (See Group 46).
Caution! Anti-freeze protection must be guaranteed to at least -30°C (-22°F). Use only nitrite-free long-term antifreeze and corrosion inhibitor. Do not top up expansion tank past the MAX mark (A).
Check antifreeze concentration in the expansion tank, top up antifreeze if necessary.
Note: Mix the coolant in a mix ratio of 50% antifreeze, 50% water.
Check coolant level in the expansion tank, top up coolant if necessary.
