Brake fluid
Fig. 301
Brake fluid reservoir
Check the brake fluid under the following conditions.
The vehicle is on a horizontal surface.
The engine is turned off.
Check brake fluid level - the brake fluid level must be between the markings
“MIN” and “MAX”» Fig. 301.
Specification - the brake fluid must comply with VW 501 14 standard (this
standard meets the requirements of FMVSS 116 DOT4).
The Braking fluid change is carried out as part of the inspection.
WARNING
■
If the date to change the braking fluid is exceeded, it can lead to steam
bubbles forming in the braking system when braking hard. This can impair
the efficiency of the brakes – risk of accident!
■
The following warning instructions must be followed at all times when
working in the engine compartment » page 260.
■
There may be an indication of a leak in the brake system, however, if the
fluid level drops significantly within a short time or if it drops below the
“MIN” » Fig. 301 marking. Stop driving – There is a risk of an accident!
Seek help from a specialist garage.
Note
A low brake fluid level which is too low is indicated by the warning light be-
ing shown on the display of the instrument cluster as well as the correspond-
ing message» page 40. We therefore recommend that you check the coolant
level directly at the reservoir from time to time.
