Engine coolant  
Introduction  
Only perform work on the engine cooling system if you are familiar with the necessary procedures and the general safety precautions, and if the correct  
equipment, fluids, and suitable tools are available. Work performed incorrectly can result in serious injuries ⇒  
. Have all work performed by suitably qualified  
professionals if necessary. Volkswagen recommends contacting your Volkswagen dealership.  
WARNING  
Engine coolant is poisonous!  
Only store engine coolant in the sealed original container and in a secure place.  
243  
Never use empty food cans, bottles, or other containers to store engine coolant, because someone could drink the engine coolant by mistake.  
Store engine coolant out of the reach of children.  
Make sure that the correct proportion of engine coolant additive is provided based on the lowest ambient temperature in which the vehicle will be  
operated.  
In extremely low temperatures, the coolant can freeze and the vehicle could break down. Because the heater will also no longer function in that situation,  
vehicle occupants could die of exposure if they do not have sufficient warm clothing.  
Coolant and coolant additives can pollute the environment. Catch any leaking operating fluids and dispose of them correctly according to environmental  
regulations.  
Engine coolant specifications  
Please read the introductory information and heed the Warnings and Notice ⇒  
and Safety precautions for working in the engine compartment .  
The cooling system is filled at the factory with a mixture of specially prepared water and at least 40% coolant additive G 12 evo (TL-VW 744 L).  
To protect the engine cooling system, there must always be at least a 40% proportion of coolant additive. If greater freeze protection is needed due to the climate,  
the proportion of coolant additive can be increased. However, the proportion of coolant additive must not exceed 55 %, because otherwise the freeze protection will  
be reduced and the cooling effect will be decreased.  
The engine coolant additive can be recognized by its purple color. The mixture of water and coolant additive provides freeze protection down to -13 °F (-25 °C),  
protects the aluminum alloy parts of the cooling system from corrosion, prevents limescale deposits, and increases the boiling point of the coolant.  
If the engine coolant is being topped up, a blend of distilled water and at least 40% of the engine coolant additive G 12 evo must be used to ensure optimum  
corrosion protection ⇒  
.
WARNING  
Insufficient freeze protection in the engine cooling system can cause engine malfunctions, which can result in serious injuries.  
Make sure that the correct proportion of engine coolant additive is provided based on the lowest ambient temperature in which the vehicle will be  
operated.  
In extremely low temperatures, the coolant can freeze and the vehicle could break down. Because the heater will also no longer function in that situation,  
vehicle occupants could die of exposure if they do not have sufficient warm clothing.  
NOTICE  
Never mix Genuine Volkswagen coolant additives with coolants that are not approved by Volkswagen.  
If the fluid in the coolant expansion tank is not pink-colored (the color comes from the mixture of the purple coolant additive with distilled water) but is, for  
example, brown instead, the suitable engine coolant was mixed with another engine coolant that is not suitable. In this case, have the engine coolant  
changed immediately. Otherwise, serious malfunctions or damage to the engine and cooling system could occur.  
Engine coolant and coolant additives can harm the environment. Catch any leaking operating fluids and dispose of them correctly according to environmental  
regulations.

Do not refill the system with engine coolant above the upper edge of the marked area . If there is too much coolant, the engine cooling system will  
become pressurized when the coolant warms up, which can result in damage.  
If there is no coolant available that conforms to the required specification, initially only top up with distilled water. Then have the correct mixture ratio  
using the specified coolant additive restored as soon as possible by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.  
Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.  
Only use distilled water for refilling the system! The chemical components contained in all other types of water can cause considerable corrosion  
damage in the engine. This can cause engine malfunctions. If water that is not distilled is added, have the fluid in the cooling system changed  
immediately by an authorized Volkswagen dealer or authorized Volkswagen Service Facility. Volkswagen recommends contacting an authorized  
Volkswagen dealer or authorized Volkswagen Service Facility.  
Do not add any engine coolant if there is no engine coolant left in the coolant expansion tank. Doing so could cause air to enter the cooling system. Do  
not continue driving. Contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance. Otherwise, the engine could be  
damaged. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.  
When topping up fluids, make sure the correct fluids are added to the correct reservoirs. Using incorrect fluids can result in malfunctions and engine  
damage.  
Brake fluid  
Fig. 144 In the engine compartment: cap on the brake fluid reservoir (version 1).  
246  
Fig. 145 In the engine compartment: cap on the brake fluid reservoir (version 2).  
Brake fluid absorbs moisture from the air over the course of time. Too much water in the brake fluid causes damage to the brake system. Water lowers the boiling  
point of the brake fluid. If the water content in the brake fluid is too high, vapor lock may form in the brake system during heavy braking and full braking. Vapor lock  
reduces the braking efficiency, increases the braking distance considerably, and can lead to a total failure of the brake system. Your own safety and the safety of  
others on the road depends on your brake system functioning correctly at all times ⇒  
.
Brake fluid specifications  
Volkswagen has developed a special brake fluid that is optimized for the vehicle's brake system. For optimum performance of the brake system, Volkswagen  
recommends only using brake fluid that complies with the VW standard 501 14.  
Before using brake fluid, check that the brake fluid specification on the bottle matches the vehicle requirements.  
Brake fluid that complies with the VW standard 501 14 can be obtained from an authorized Volkswagen dealer or authorized Volkswagen Service Facility.  
If brake fluid that meets this specification is not available and another high-quality brake fluid must therefore be used, brake fluid that complies with the specification  
DIN ISO 4925 or the US Standard FMVSS 116 DOT 4 CLASS 6 can be used.  
Not all brake fluids that comply with the requirements of DIN ISO 4925 or US Standard FMVSS 116 DOT 4 CLASS 6 have the same chemical composition. Some  
of these brake fluids can contain chemicals that can destroy or damage components of the vehicle brake system over time.  
To help ensure that the brake system functions correctly over the long term, Volkswagen recommends using a brake fluid that expressly conforms to the  
VW standard 501 14.  
Brake fluid that complies with the VW standard 501 14 meets the requirements of DIN ISO 4925 or the US Standard FMVSS 116 DOT 4 CLASS 6.  
Brake fluid level  
The brake fluid level must always be between the MIN and MAX markings on the brake fluid reservoir  
.
The brake fluid level cannot be checked precisely on all models because the hood or engine components may obstruct the view of the fluid level in the reservoir. If  
you cannot read the brake fluid level clearly, see an authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance.  
The brake fluid level decreases slightly when the vehicle is being used as the brake pads wear and the brakes automatically adjust themselves.  
Brake fluid level  
The red warning light turns on.  
Brake fluid level is too low.  
1.  
Do not continue driving!  
2. Check the brake fluid level.  
If the brake fluid level is too low:  
1. Inform a suitably qualified professional.  
2. Have the brake system checked.  
Changing brake fluid  
Have the brake fluid changed by suitably qualified professionals. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen  
Service Facility. Only use new brake fluid that meets the required specifications.  
247  
WARNING  
Low brake fluid, brake fluid that is too old, or using an incorrect type of brake fluid can cause brake malfunctions or reduced braking efficiency. Hard braking  
when the brake fluid is old can cause vapor lock to form in the fluid due to absorbed moisture. Vapor lock reduces the braking efficiency, increases the braking  
distance considerably, and can lead to a total failure of the brake system.  
Have the brake system and brake fluid level checked or have the brake fluid changed regularly.  
Only have new brake fluid added.  
Be sure to use the correct brake fluid. Only use brake fluid that expressly complies with the VW standard 501 14. Any other brake fluid or brake fluid that  
is not high-quality can impair the braking function and reduce the braking efficiency.  
If brake fluid that complies with the VW standard 501 14 is not available and it is absolutely necessary to use a different brake fluid, only use a high-  
quality brake fluid that complies with DIN ISO 4925 CLASS 6 or US standard FMVSS 116 DOT 4.  
WARNING  
Brake fluid is poisonous.  
To reduce the risk of poisoning, never store brake fluid in beverage containers or other containers. A person could mistakenly drink from the container,  
even if the container is marked.  
Always store brake fluid in the sealed original container and keep it out of the reach of children.  
NOTICE  
Spilled or leaking brake fluid damages vehicle paint and tires.  
Immediately wipe up any spilled or leaking brake fluid that comes into contact with vehicle components.  
Brake fluid can pollute the environment. Collect spilled brake fluid and dispose of it correctly.
