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 Start by turning the cap counter-
clockwise. Pause to allow any
accumulated pressure to escape,
then open.
2 If the coolant is low, slowly add
coolant 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 re-
quired.
Replace the coolant every four years.
If the indicator lamp for the
brake hydraulic system appears
or if the "CHECK BRAKE FLUID"
warning 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. Should you de-
termine that the brake fluid is low, refer
the problem to your BMW center, who
can trace and rectify any sources of
leakage when refilling the reservoir.
Your BMW center is familiar with the
specifications for approved brake fluids
(DOT 4).
Brake fluid loss results in extended
pedal travel. For this situation, refer to
the notes on page 130.
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 authorized 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. You should always store
it in its original container and in a loca-
tion 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
contact with hot engine parts and cause
serious burns.<
Comply with the applicable
environmental laws regulating the
disposal of brake fluid.<
