Checking the brake fluid level

WARNING
Service product can be poisonous and haz-
ardous to health. There is a risk of injury.
Observe the instructions on the respective
original container when using, storing and dis-
posing off service products. Always store ser-
vice products in the sealed original container.
Always keep service products out of the reach
of children.
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.
Brake fluid is hazardous to health. Also observe
the safety notes under "Service products"
(
Y
page 223).
Have the brake fluid renewed every two years at
a qualified specialist workshop.
The clutch actuation system and the brake sys-
tem are operated hydraulically using brake fluid.
Check the brake fluid level regularly, e.g. weekly
or when refuelling.
X
Park the vehicle on an even surface.
X
Check the brake fluid level.
The brake fluid level is adequate if the level is
between the MIN mark and MAX mark on
brake fluid reservoir
:
.
X
Have the brake fluid refilled at a qualified spe-
cialist workshop if the brake fluid level is
below the MIN mark.
