| t
| Brake filling and bleeding device, e.g. -VAS 5234- |

| Vehicle system tester -V.A.G 1552- with diagnostic cable -V.A.G 1551/3, 3A, 3B oder 3C- or diagnostic unit VAS (only vehicles with ABS/EDL) |
WARNING | t
| Brake fluid is hygroscopic, i.e. it retains humidity from the ambient air, and must therefore always be stored in airtight containers. |
| t
| Brake fluid must never come into contact with fluids containing mineral oils (oil, petrol, cleaning agent). Mineral oils damage the plugs and boots of the brake system. |
| t
| Drained (used) brake fluid must never be used again. |
| t
| Observe the disposal instructions! |
| t
| Brake fluid is toxic, avoid skin contact. |
| t

| t
| Rinse any brake fluid spills with a lot of water. |
| t
| Dispose of brake fluid in compliance with the applicable environmental regulations. |
