NOTE:

Read the cut-off line to obtain an accurate value for the following tests. Place a drop of water on the glass using a pipette to improve the readability of the cut-off line. The cut-off line can be clearly recognized on the "WATERLINE".

-- Check the coolant additive concentration using the :T10007A . Refer to the operating instructions.

The scale -1- on the refractometer applies to coolant additive G12 Plus Plus.

The scale -2- only applies to coolant additive G13.

-- Drain some of the coolant and add coolant additive if the freeze protection if the frost protection is inadequate. Refer to COOLANT LEVEL, CHECKING AND FILLING IF NECESSARY .

NOTE:

If it cannot clearly determined which coolant additive is in the coolant system, use the scale -2- for coolant additive G13.

Please follow all waste disposal regulations!

-- Check the concentration of the coolant additive again after the road test.
