Read the bright/ark boundary to obtain an accurate reading for the following tests. Place a drop of water on the glass to improve the readability of the bright/dark boundary. The bright/dark boundary can be clearly recognized on the "WATERLINE".

-- Check the concentration of the anti-freeze additive using T10007 (operating instructions).

Scale -1- of refractometer applies to Windshield Cleanser Concentrate G 052 164.

The scale -2- is designed for commercially available windshield cleanser as well as a mixture of commercially available windshield cleanser and Windshield Cleanser Concentrate G 052 164.

Mixture Ratio

Freeze Protection to	Window Washer Fluid Concentrate G 052 164	Water
in summer	1 part	4 part
-16 °C	1 part	2 part
-35 °C	1 part	1 part
-40 °F/C	2 part	1 part

Filling-up with Fluid:

The windshield washer system fluid reservoir must be filled.

Use only Windshield Cleanser Concentrate G 052 164 when filling the windshield washer fluid reservoir.

NOTE:

Windshield Cleanser Concentrate G 052 164 protects the spray nozzles, the reservoir and the hoses from freezing.

All vehicles with fan type spray nozzles must be filled with Windshield Cleanser Concentrate G 052 164 as this fluid has a low viscosity at minus temperatures. The complicated spray jet system could otherwise become blocked due to crystallized washer fluid that can affect the fan pattern of the spray nozzle. Windshield Cleanser Concentrate G 052 164 assures that the fan type spray nozzles remain functional even at low temperatures.

Fill with Windshield Cleanser Concentrate G 052 164 in the warmer season also. The powerful cleanser removes wax and oil deposits from the windows.

Freeze protection (anti-freeze) must be guaranteed to approximately -13 °F (-25 °C) (approximately -31 °F (-35 °C) in countries with an arctic climate) in the washer system.

In case of an uneven spray field due to dirt in spray nozzles, remove nozzle. Refer to [For transmission(s) 0A4, 02E, 09G, 02Q] [For engine(s) BRM, BGP, BPY, BGQ, CBTA, CBEA, CJAA, CBUA, CCTA, CBFA] Removal and Installation and flush out with water opposite to spraying direction.

Subsequently blowing through in the opposite direction of the spray flow with compressed air is permitted.

CAUTION:

Do not use solid objects to clean the spray nozzles!
Do not use a needle or similar under any circumstance to adjust spray nozzles, otherwise the water hoses in the spray nozzles may be damaged!
