• Pre-delivery inspection: coolant level minimum to the "MAX mark".
• At the pre-delivery inspection a coolant level above the "MAX mark" is permitted.
• Extracting the increased coolant level is not necessary because the coolant level can be lowered on new vehicles through the venting process.
• Inspection: coolant level above "MIN mark".

-- Ob hybrid vehicles check the additional coolant reservoir.
