Service fluids -> Brake fluid for Your Volkswagen Tayron SUV First Generation (2018-2025)

Brake fluid will gradually absorb water from the surrounding air over the course of time. The brake system will be damaged if there is  
too much water in the brake fluid. The boiling point of the brake fluid is also considerably reduced by the water content. Heavy use of  
the brakes may cause a vapour lock in the brake system if the water content is too high. Vapour locks reduce the braking efficiency,  
considerably increase braking distance and can even cause the brake system to fail completely. Your own safety and that of other road  
users depends on having a brake system that functions properly at all times.  
WARNING  
Brake fluid is toxic. Contact with brake fluid – particularly if swallowed – can lead to serious or fatal injuries.  
Consult a doctor immediately if you have swallowed brake fluid.  
Consult a doctor if you experience health problems after working with brake fluid.  
Always keep brake fluid out of the reach of children and only in the closed original container.  
Never store brake fluid in empty food containers, bottles or any other non-original containers as people finding these containers  
could drink the brake fluid in them.  
Avoid regular contact with brake fluid in order to prevent damage to the skin.  
Protect your skin, face and particularly your eyes when working with brake fluid.  
Do not eat, drink or smoke when working with brake fluid.  
Wash your skin with soap and water after working with brake fluid.  
NOTICE  
Brake fluid that has leaked or been spilled will attack vehicle surfaces. The vehicle paintwork, plastic parts and tyres could be  
damaged as a result.  
Wipe off brake fluid that has leaked or been spilled immediately from all parts of the vehicle.  
Then rinse all components with sufficient amounts of water.  
Brake fluid can pollute the environment.  
Collect any service fluids that escape or are spilled and dispose of them in a proper and environmentally responsible  
manner.  
Volkswagen has developed a brake fluid that has been optimised for the brake system in the vehicle. To ensure the best possible  
operation of the brake system, Volkswagen expressly recommends the use of brake fluid compliant with VW standard 501 14.  
Before using a particular brake fluid, check that the specifications printed on the container correspond to the vehicle requirements.  
Brake fluid that is compliant with VW standard 501 14 is available from authorised Volkswagen repairers.  
If such a brake fluid is not available and another high-quality brake fluid must be used for this reason, a brake fluid can be used that  
meets the requirements of DIN ISO 4925 or the US standard FMVSS 116 DOT 4 CLASS 6.  
Not all brake fluids that are compliant with DIN ISO 4925 or US standard FMVSS 116 DOT 4 CLASS 6 have the same chemical  
composition. Some of these brake fluids may contain chemicals that can damage or destroy brake system components over time.  
Brake fluid that is compliant with VW standard 501 14 fulfils the requirements of DIN ISO 4925 or US standard  
FMVSS 116 DOT 4 CLASS 6.  
Preparations  
1. Park the vehicle safely on a horizontal and firm surface (→ Parking).  
2. Open the bonnet.  
Checking the brake fluid level  
In the bonnet space: cap of the brake fluid reservoir.  
The brake fluid reservoir can be recognised by its cap → Fig. 1.  
The brake fluid level cannot be checked accurately in all models as a flap or engine components may partially conceal the brake fluid  
container.  
If the brake fluid level cannot be read exactly, please seek assistance from a suitably qualified workshop. Volkswagen recommends  
using an authorised Volkswagen repairer.  
If the brake fluid is not between the min. and max. markings of the brake fluid reservoir, seek assistance from a suitably qualified  
workshop . Volkswagen recommends using an authorised Volkswagen repairer.  
The brake fluid level drops slightly during vehicle operation as the brake pads wear and the brakes are automatically adjusted.  
WARNING  
An overly low brake fluid level or unsuitable brake fluid can cause brake failure or reduced braking efficiency. This can result in  
accidents and serious or fatal injuries.  
Have the brake system and brake fluid level checked regularly.  
Make sure that the correct brake fluid is used.  
Use only brake fluid that is explicitly compliant with VW standard 501 14.  
Use a high-quality brake fluid in accordance with DIN ISO 4925 CLASS 6 or US standard FMVSS 116 DOT 4, only in exceptional  
cases if a brake fluid according to VW standard 501 14 is not available.  
Changing the brake fluid  
Suitably qualified workshops can provide information on the intervals for changing the vehicle’s brake fluid. Volkswagen recommends  
using an authorised Volkswagen repairer.  
The brake fluid should be changed regularly.  
Only brake fluid that conforms with the required specification should be used.  
WARNING  
Old brake fluid can form vapour bubbles due to absorbed moisture when the brakes are subjected to heavy use and reduce the  
braking effect to the point of total failure. This can result in accidents and serious or fatal injuries.  
Have the brake fluid changed regularly.  
Have the brake system filled only with new brake fluid.  
Brake fluid level  
The warning lamp lights up red. The brake fluid level is too low.  
Do not drive on! This can result in brake failure.  
1. Stop the vehicle immediately as soon as it possible and safe to do so (→ Parking).  
2. Check the brake fluid level.  
3. Seek expert assistance if the brake fluid level is too low.
