Brake fluid level
The warning lamp for the brake
system hydraulic circuits comes
on and/or the message "CHECK
BRAKE FLUID" appears in the
Check Control:
Brake fluid level too low.
To add brake fluidThe brake fluid reservoir is located
under the microfilter housing on the
driver's side of the vehicle. For adding
brake fluid or for determining and cor-
recting the cause of brake fluid loss,
consult your BMW center. Your BMW
center is familiar with the specifications
for factory-approved brake fluids
(DOT 4).
Brake fluid loss may result in extended
brake pedal travel. If this occurs, refer
to the information on page 108.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years at
a BMW center. Refer also to the Service
and Warranty Information Booklet (US
models) or the Warranty and Service
Guide Booklet (Canadian models).
Brake fluid is hazardous to health and
damages the vehicle's paint. You
should always store it in its original
container and in a location which is out
of reach of children. Do not spill the
fluid and do not fill the brake fluid reser-
voir beyond the MAX mark. The brake
fluid could ignite upon contact with hot
engine parts and cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of brake fluid.<
