Brake fluid
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
To add coolant
Wait until the engine cools before re-
moving the cap from the expansion
tank. The needle of the coolant temper-
ature gauge in the instrument cluster
must be located in the blue zone; other-
wise, there is a danger of scalding.
over time.
In order to ensure the operating safety
of the brake system, have the brake
fluid changed every two years by your
BMW center. Refer also to the Service
and Warranty Information Booklet (US
models) or to the Warranty and Service
Guide Booklet (Canadian models).
Brake fluid is toxic and damages the
vehicle's paint. Always store brake fluid
in the original containers. Keep the con-
tainers tightly closed and out of reach
of children.
1 Start by turning the cap counter-
clockwise. Pause to allow any accu-
mulated pressure to escape, then re-
move the cap
2 If the coolant is low, slowly add cool-
ant until the correct level is reached –
do not overfill.
Brake fluid level
If the brake hydraulic system
warning lamp comes on, or if
the message "CHECK BRAKE
FLUID" appears in the Check
Control display: The brake fluid
level is too low in the reservoir.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the pre-
scribed all-season 50:50 mixture ratio
for year-round protection against inter-
nal corrosion. No other additives are re-
quired.
Do not spill brake fluid. Do not fill be-
yond the "MAX" level in the reservoir.
The brake fluid could ignite upon con-
tact with hot engine parts and cause
serious burns.<
Fill up to upper mark ("MAX" level visi-
ble through the transparent reservoir).
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of brake fluid.<
Any BMW center can provide you with
information on factory-approved brake
fluids (DOT 4).
Replace the coolant every four years.
Brake fluid loss results in extended
pedal travel. Refer to the information on
page 132.
