The brake flui dconstantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
flui dist oo low ,vapo rpockets may form in the
brake system when the brakes are applied
hard .This would impair braking efficiency.
There is arisk of an accident.
You should have the brake flui drenewe dat
the specified intervals.
!If the brake flui dlevelint he brake flui dres-
ervoir has fallen to the MIN mark or below,
check the brake system immediatel yfor
leaks. Also check the thickness of the brake
linings. Visi taqualified specialist workshop
immediately.
Do not add brake fluid. This does not correct
the malfunction.
!Brake flui dcorrodes paint, plastic and rub-
ber. If paint, plastic or rubber has come into
contact with brake fluid, rinse with water
immediately.
Have the brake flui drenewe devery 2years at a

opening the hood. If there is afire in the
engine compartment, keep the hood closed
and contact the fire department.
GWARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts

If th eindicator/warning lamps do no tlight up in
th ei nstrumen tcluste rwhen temperatures are
low, it is probably because th edischarged bat-
tery has frozen.S hould this be th ecase, do not
jump-star tthe vehicle or charge th ebattery. The
servic elife of athawed battery may be shorter.
Start-up behavior may deteriorate, in particular
at low temperatures. Hav ethe thawed battery

Care
!
Dirt ybattery clamps and battery surfaces
cause leak currentsw hich lead to the batter-
ies discharging.
!Do not use cleaning agents containing fuel.
Cleaning agents containing fuel corrode the
battery housing.
!If dirt gets into the battery cell, battery self-
discharge will increase and the battery may
be damaged.
The following points on battery care must be
observed:
XRegularly check the battery terminals and the
fastening of the negative cable to the chassis
to ensure that they are firmly seated.
XAlways keep the battery terminals and battery
surfaces clean and dry.
XLightly grease the undersides of the battery
terminals with acid-resistant grease.
XOnly clean the battery casing with acommer-
