Radiator fan
ä
First read and observe the introductory information and safety warn-
ings
on page 175.
The radiator fan is driven by an electric motor and controlled according to the
coolant temperature.
After switching off the ignition, the radiator fan can intermittently continue to op-
erate for approx. 10 minutes.

ings

Check the level of brake fluid in the reservoir
tween the "MIN" and "MAX" markings.
When driving, a slight drop in the fluid level is caused by the wear-and-tear and
automatic adjustment of the brake pads, and is therefore perfectly normal.
There may be an indication of a leak in the brake system, however, if the fluid lev-
el drops significantly within a short time or if it drops below the "MIN" marking. If
the brake fluid level is too low, this is indicated by the warning light
in the instrument cluster

WARNING
If the fluid level has dropped below the MIN marking, do not continue your
journey - risk of accident! Get professional assistance.
Changing the brake fluid
ä
First read and observe the introductory information and safety warn-
ings
on page 175.
Brake fluid absorbs moisture. Over time it therefore absorbs moisture from the
environment. Excessive water in the brake fluid may be the cause of corrosion in
the brake system. The water content also lowers the boiling point of the brake
fluid.
The brake fluid must comply with one of the following standards or specifications:
›
VW 50114
›
FMVSS 116 DOT4
WARNING
Using old brake fluid can result in severe stress on the brakes because of the
formation of vapour bubbles in the brake system. This greatly impairs the
braking efficiency and thus also the safety of your vehicle.
CAUTION
Brake fluid damages the paintwork of the vehicle.
