♦ Refractometer - T10007 A-  
Note  
In countries and regions where no frost occurs due to the local  
climatic conditions, the anti-freeze protection does not need to be  
checked.  
Read precise value for the following tests at light/dark boundary.  
Using a pipette, place a drop of water on the glass to improve the  
readability of the light/dark boundary. The light-dark border can  
be clearly recognised on the “WATERLINE”.  
– Check concentration of anti-freeze additive using refractome‐  
ter - T10007 A- .  
The scale -4- of the refractometer is applicable for the anti-freeze  
protection of the window wash/wipe system.

– Top up fluid in window wash/wipe system (only if customer  
requests to do so).

dow wash/wipe system.  
Depending on season, a winter product with anti-freeze protection  
or a summer product with increased cleaning capabilities should  
be used.  
Ready-to-use window cleaner (Ready Mix) does not need to be  
mixed with water.

Note  
Genuine washer fluid ⇒ ETKA prevents the spray jets, washer  
fluid reservoirs and connecting hoses from freezing.  
In vehicles with fan jets, the reservoir must be filled with Gen‐  
uine washer fluid, as this fluid has a low viscosity at tempera‐  
tures below freezing. Otherwise the complicated spray jet  
system can become blocked by the crystallised washer fluid,  
which affects the spray pattern of the spray jet. Genuine wash‐  
er fluid ensures that the fan jets remain fully functional at low  
temperatures.  
Genuine washer fluid ⇒ ETKA can also be used in the sum‐  
mer. The powerful cleanser easily removes wax and oil resi‐  
due from the glass.  
Frost protection must be guaranteed to approx. -25°C (approx.  
-35°C in countries with an arctic climate) in the windscreen  
wash/wipe system.

Window wash/wipe system: checking  
spray jet settings and adjusting if nec‐  
essary  
Special tools and workshop equipment required  
♦ Adjusting tool - T10564-  
♦ or adjusting tool - T40187-  
Note  
If the spray field is uneven due to soiling in the spray jet, remove  
the spray jet. Rinse it then with water opposite to direction of  
spray. Subsequent blowing through with compressed air against  
the spraying direction is permitted. Never use solid objects to  
clean the washer jets!
