continuing your journey.
To ensure the full pe dal trave l can be

of the brake circuits, there must be no

Brake and clutch fluid le ve l
The fluid lev el in the containe r must be
neither higher than the MAX mark nor
low er than the MIN mark.Use of c ertain brake/clutch fluids can lead
to dam age or reduce d braking e ffect.
We therefore recommend that you use
only high pe rform anc e brak e/ clutch fluid
app rov ed.
W hen topping up, ens ure max imum
cle anline ss , as contamination of the b ra ke/
clutch fluid can lead to function problems
in the braking s ys te m.
After corre cting the brak e/clutch fluid lev el,
have the cause of brake/clutch fluid loss
re medie d by a works hop.
9 Warning
Brake /clutch fluid is poisonous and
corrosive . Do not allow it to c ontact e yes,

15 7Self-help, vehicle care
Brak e/clut ch fluid c ha nge
Brake /clutch fluid is hygroscopic, i.e . it
absorbs water. If the brak es be come hot,
s uc h as whe n driving on long downhill
stretches, va pour bubbles can occur in the
water, which can have an extrem ely
adv ers e e ffe ct on braking power
( dep en di n g o n t h e p ro p o r t i o n o f w a t e r) .

chapter "Service, Maintenance" on

Power steering fluid
The power steering fluid does not require
any additional ma inte na nce than that
detaile d in the c hap te r "S ervice ,
Mainte nance" on page 16 5 .
If the fluid in the re s ervoir falls below the
HOT mark on the dipstick, consult a
work shop.
