Coolant Brake fluid
Adding coolant
Wait until the engine cools before re-
moving the cap from the expansion
tank. The needle of the coolant gauge
in the instrument cluster must be lo-
cated in the blue zone; otherwise, there
is a danger of scalding.
1 Turn the cap counterclockwise
slightly in order to allow accumulated
pressure to escape. Then open.
2 If the coolant is low, slowly add cool-
ant until the correct level is reached –
do not overfill.
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
required.
Replace the coolant every three years.
Brake fluid level
If the indicator lamp for the brake
hydraulic system appears or if
the "CHECK BRAKE FLUID"
message appears in the Check
Control: The brake fluid level is
too low in the reservoir.
The brake fluid reservoir is located
under the microfilter housing on the
driver's side of the car. For adding brake
fluid or for determining and correcting
the cause of brake fluid loss, consult
your BMW center. Your BMW center is
familiar with the specifications for fac-
tory-approved brake fluids (DOT 4).
Brake fluid loss may result in extended
brake pedal travel. If this occurs, refer
to the information on page 112.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time. In order to ensure the safety
and reliability of the brake system, have
the brake fluid changed every two years
by an BMW center. Refer also to the
Service and Warranty Information Book-
let (US models) or the Warranty and Ser-
vice Guide Booklet (Canadian models).
Brake fluid is toxic and damages the ve-
hicle'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 reservoir beyond the "MAX" mark.
The brake fluid could ignite upon con-
tact with hot engine parts and cause se-
rious burns.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of brake fluid.<
