Anti-freeze: checking protection of flu‐
id, topping up fluid if necessary
Special tools and workshop equipment required
♦ Refractometer -T10007A-
♦ Refractometer -T10007B-
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 boun‐
dary. 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 refractom‐
eter.
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).
Use genuine washer fluid ⇒ ETKA throughout all year to fill
window wash/wipe system.
Depending on season, a winter product with anti-freeze protec‐
tion 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, wash‐
er fluid reservoirs and connecting hoses from freezing.
♦ In vehicles with fan jets, the reservoir must be filled with
Genuine washer fluid, as this fluid has a low viscosity at tem‐
peratures 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. Genu‐
ine washer fluid ensures that the fan jets remain fully func‐
tional 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 (ap‐
prox. -35°C in countries with an arctic climate) in the wind‐
screen wash/wipe system.

Window wash/wipe system: checking
spray jet settings and adjusting if nec‐
essary
Note
In case of uneven spray field due to impurities in the spray jet:
remove spray jet, and rinse it through with water, opposite to di‐
rection of spray. Subsequent blowing through with compressed
air against the spraying direction is permitted. Never use imple‐
ments to clean the spray jets.
Windscreen spray jet settings
The spray jets are preset. However, small differences in height
may be corrected.
