Engine coolant -> Engine coolant specifications for Your Volkswagen Passat SUV Seventh Generation (2010-2014)

When the ignition is switched on, several warning and indicator lights  
come on briefly for a function check. They go out after a few seconds.  
WARNING  
Failure to heed warning lights and instrument cluster text mes-  
sages can cause the vehicle to break down in traffic and result  
in a collision and serious personal injury.  
Never ignore warning lights or text WARNINGS.  
Always stop the vehicle as soon as it is safe to do so.  
NOTICE  
Failure to heed warning lights or text WARNINGS can result in  
vehicle damage.  
Engine coolant specifications  
¤ Please first read and note the introductory information and  
heed the WARNINGS  
The engine cooling system is filled at the factory with a mixture of  
specially conditioned water and at least 40 percent of Volkswagen  
engine coolant additive G 13 (TL-VW 774 J). This engine coolant ad-  
ditive is pink.  
This mixture provides antifreeze protection down to -13 °F (-25 °C). It  
also helps to protect the light alloy parts in the engine cooling system  
against corrosion. In addition, the mixture helps prevent calcium de-  
posits and increases the boiling point of the engine coolant.  
To protect the engine, the mixture must always contain at least 40%  
coolant additive even in warm weather or climates where antifreeze  
protection is not needed.  
If more antifreeze protection is needed for climate conditions, the per-  
centage of coolant additive can be increased. However, the coolant  
additive percentage must never be more than 60%; otherwise, anti-  
freeze protection is reduced and the ability of the mixture to cool the  
engine is also reduced.  
When adding engine coolant, use a mixture of distilled water and at  
least 40% coolant additive G 13 or G 12 plus-plus (TL-VW 774 G) for  
optimum corrosion protection .  
Do not mix G 13 with G 12 plus or G 11. Mixing these coolant addi-  
tives together significantly reduces corrosion protection and can  
lead to engine damage that is not covered by any Volkswagen Lim-  
ited Warranty.  
WARNING  
Too little antifreeze protection in the engine cooling system can  
cause engine failure and severe injuries.  
Always make sure there is enough of the correct coolant ad-  
ditive to provide proper antifreeze protection at the coldest  
temperatures that can be expected where the vehicle will be  
used.  
At extremely cold temperatures, the coolant could freeze,  
causing the vehicle to break down. The heater would also not  
work, and vehicle occupants could be without protection at  
subfreezing temperatures.  
NOTICE  
Never mix original Volkswagen engine coolant additives with  
other additives not approved by Volkswagen. Mixing  
Volkswagen coolant additives with coolant additives made by  
other manufacturers can seriously damage the engine and the  
engine cooling system.  
If the fluid in the engine coolant reservoir is any color but pink,  
then G 13 was mixed with a different engine coolant. If this is the  
case, the engine coolant must be replaced immediately. Other-  
wise serious malfunctions or engine damage can occur!  
Engine coolant and engine coolant additives can pollute the envi-  
ronment. Collect leaking operating fluids and dispose of them proper-  
ly in accordance with applicable environmental laws and regulations.
