Coolant

Brake fluid

Adding coolant

Wait until the engine cools before
removing the cap from the expansion
tank. The needle of the coolant gauge
in the instrument cluster must be
located in the blue zone. If it is not,
there is a danger of scalding.

1 Turn the cap slightly counterclock-

wise in order to allow 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
prescribed all-season 50:50 mixture
ratio for year-round protection against
internal corrosion. No other additives
are required.

Replace the coolant every four years.

If the brake warning lamp comes on
and the parking brake has been
released:
Check the brake fluid level. Fill it to the
top mark ("MAX") if necessary.

For adding brake fluid or for deter-
mining and correcting 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 can result in extended
pedal travel. Comply with the informa-
tion provided on page

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 by
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 toxic and damages the
vehicle's paint. You should always store
it in its original container and in a loca-
tion inaccessible to 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 envi-
ronmental laws regulating the

disposal of brake fluid.
