bed in the following.
Brake fluid is hazardous to health. Also observe
the safety notes in the "Service products and

capacities" section (
G
WARNING
The brake fluid continuously absorbs mois-
ture from the air. This results in the boiling
point of the brake fluid lowering. If the boiling
point of the brake fluid is too low, vapour
pockets may form when the brakes are sub-
jected to a heavy load. This would impair brak-
ing efficiency. There is a risk of an accident.
Have the brake fluid renewed at the prescri-
bed intervals.
! If the brake fluid level in the brake fluid res-
ervoir has fallen to the minimum mark or less,
check the brake system immediately for
leaks. Also check the thickness of the brake
pads/linings. Visit a qualified specialist work-
shop immediately.
Do not top up the brake fluid. This does not
solve the problem.
! Brake fluid corrodes paint, plastic and rub-
ber. If brake fluid comes into contact with
paint, plastic or rubber, rinse with water
immediately.
