General
The coolant level is shown by Min and Max

different positions depending on the coolant

compartment.
To guarantee operational safety of the vehicle,
always check the coolant levels of both coolant
tanks.

tank is located on the right or left of the engine
compartment.
Not all commercially available additives are suita‐
ble for the vehicle. Information regarding suitable
additives is available from a Service Partner of
the manufacturer or another qualified Service
Partner or a specialist workshop.
