Engine coolant -> Warning light and engine coolant temperature gauge for Your Volkswagen Passat SUV Seventh Generation (2010-2014)

WARNING  
Engine coolant is poisonous!  
Always keep the coolant in its original container stored in a  
safe place.  
To reduce the risk of poisoning, never store engine coolant in  
empty food or beverage containers or in any other containers  
that might mislead someone into drinking from them.  
Always keep engine coolant out of reach of children.  
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.  
Coolant and coolant additives can pollute the environment. Col-  
lect leaking operating fluids and dispose of them properly in accord-  
ance with applicable environmental laws and regulations.  
Warning light and engine coolant temperature gauge  
Fig. 167 Engine coolant temperature gauge in the instrument cluster:  
A Engine cold; B Normal temperature range; C Warning zone.  
¤ Please first read and note the introductory information and  
heed the WARNINGS  
If the indicator in the engine coolant temperature gauge is located in  
the cold range (A), the engine has not reached operating tempera-  
ture. High engine speeds and heavy engine loads should be avoided.  
Under normal driving conditions, the needle should be in the middle  
of the gauge. The temperature may go higher when the engine is  
working hard, especially in hot weather.  
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.  
The following table explains what to do if the engine coolant tempera-  
ture warning light ~ does not go out a few seconds after the engine  
is started or starts flashing while driving.

Pull off the road and stop  
as soon as you can do so  
safely. Stop the engine  
and let it cool down until  
the temperature needle is  
in the normal range again.  
Check the engine coolant

If the coolant level is cor-  
rect, the overheating may  
be caused by a radiator  
fan fault. Check the fuses  
and replace as necessary.

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.
