Operating fluids and media  
All operating fluids and media, such as engine  
coolant or vehicle batteries, are subject to continuous  
development. In the case of combustion engines, also  
engine oils. For this reason, go to a duly qualified  
specialized workshop when you have to change any  
fluid or operating medium. Volkswagen recommends  
a Volkswagen dealer.

Check the level of the window washer fluid regularly  
and top up if necessary.  
Inappropriate or improperly used fluids and  
operating media can cause serious accidents,  
injuries, burns and poisoning.  
There is a strainer in the window washer fluid tank  
filler neck. When filling the tank, this sieve retains  
large dirt particles from reaching the ejectors. Do not  
remove the sieve except to clean it. If the strainer is  
damaged or not fitted, these dirt particles could get  
into the system during filling and clog the washer jets.  
· Store operating fluids only in their original tightly  
closed containers.  
· Never store operating fluids in food cans, bottles or  
other empty containers, as they could be  
swallowed by someone.  
1. Open the front hood ÿ p. 334.  
Keep liquids and operating media out  
out of the reach of children.
