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.

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.

¤ Please first read and note the introductory information and  
heed the WARNINGS  
If the coolant level drops too low, the engine coolant lev-  
el/temperature warning light lights up.  
Preparations  
Park the vehicle on level ground.  
Always let the engine cool down ꢀ  
Open the engine hood ž  
.
There is a « symbol on the cap of the engine coolant expansion  
tank fig. 169.  
Checking engine coolant level  
When the engine is cold, check the engine coolant level relative to  
the marking on the side of the expansion tank fig. 168.  
If the coolant level in the tank is below the minimum mark (“min”),  
add coolant. When the engine is warm, the engine coolant level may  
be slightly above the upper edge of the marked range.  
Adding engine coolant  
Always protect face, hands and arms from hot escaping coolant or  
steam by covering the cap with a large, thick rag.  
Carefully unscrew the cap ꢀ  
.
Add only new engine coolant according to Volkswagen specifica-  
tions (Engine coolant specifications) .  
The engine coolant level must be inside the marks on the side of  
the reservoir fig. 168. Do not fill above the top edge of the filling  
range! ꢀ  
Screw the lid tightly.  
Even in an emergency, do not use any other kind of coolant addi-  
tive if engine coolant meeting Volkswagen specifications (page 456,  
Engine coolant specifications) is unavailable! Instead, add distilled  
water only . As soon as possible, have the correct coolant ratio  
restored using engine coolant that meets Volkswagen specifications  
Engine coolant specifications.  
WARNING  
Hot steam and hot engine coolant can cause serious burns.  
Never open the hood if you see steam or coolant escaping  
from the engine compartment. Always wait until you no longer  
see or hear steam or coolant escaping from the engine.  
Always let the engine cool down completely before carefully  
opening the hood. Hot components will burn skin on contact.  
When the engine has cooled down and you are ready to open  
the hood:  
– Apply the electronic parking brake and shift the transmis-  
sion into Park (P) (automatic) or Neutral (manual only).  
– Take the vehicle key out of the ignition.  
– On vehicles with Keyless Access, make sure that the re-  
mote control vehicle key is out of range of the vehicle and  
that the vehicle cannot be started by depressing the starter  
button  
– Always keep children and others away from the engine  
compartment and never leave them unsupervised.  
The engine coolant system is under pressure when the en-  
gine is hot. Never unscrew the coolant expansion tank cap  
when the engine is hot. Hot coolant can spray out and cause  
severe burns and other serious injuries.  
– Turn the cap slowly and very carefully in a counterclock-  
wise direction while applying light downward pressure on the  
top of the cap.  
– Always protect your face, hands, and arms from hot escap-  
ing coolant or steam by covering the cap with a large, thick  
rag.  
Never spill fluids on the engine or exhaust system when re-  
filling. Spilling fluids onto hot parts of the engine or exhaust  
system can cause a fire. Under some conditions, the ethylene  
glycol in engine coolant can catch fire.  
NOTICE  
Use distilled water only when adding coolant! All other types  
of water contain chemical compounds that can cause extensive  
corrosion damage to the engine. This can even lead to engine  
failure. If you have added non-distilled water, take the vehicle  
immediately to an authorized Volkswagen dealer or an author-  
ized Volkswagen Service Facility to have the coolant system  
drained, flushed, and refilled completely with the proper coolant.  
Refill engine coolant only up to the top edge of the marked fill  
range fig. 168. Excess engine coolant may be forced out of the  
engine cooling system when it gets hot and cause damage.  
In the case of significant engine coolant loss, refill engine  
coolant only when the engine is completely cooled down. Signif-  
icant engine coolant loss is a sign of leaks in the cooling sys-  
tem. Have the engine cooling system checked immediately by an  
authorized Volkswagen dealer or an authorized Volkswagen Ser-  
vice Facility. Otherwise the engine may be damaged!  
When changing or topping off operating fluids, make sure that  
you pour the fluids into the correct reservoirs. Serious malfunc-  
tions and engine damage can result if you pour operating fluids  
into the wrong reservoir.
