1. Turn the cap on the expansion tank
slightly anti-clockwise until it starts to
open, then allow the pressure to escape
before opening it fully
2. The coolant level is correct if it is
between the maximumandminimum marks
in the filler neck (see also diagram next to

Brake fluid
The symbol lights up and a
message appears in the Check
Control: the brake fluid level in the
reservoir is too low.
The brake fluid reservoir is located under
the micro-filter housing on the driver's side.
To top up the brake fluid, or to rectify the
cause of any loss of brake fluid, please
consult BMW Service which is familiar with
the factory-approved grades of brake fluid
DOT4.
Brake fluid is hygroscopic, that is to
say it absorbs moisture gradually from
the air.
To ensure that the brake system remains
fully operational, have the brake fluid
renewed every two years by BMW Service,
see page 78 and the Service Booklet.
Brake fluid constitutes a health hazard and
also attacks the car's paint. Store it in
sealed original packs, out of reach of chil-
dren. Do not spill brake fluid; add it only up
to the MAX mark on the reservoir. If it
comes into contact with hot parts of the
engine, brake fluid may ignite and cause
burns.
<
When disposing of old brake fluid,
comply with the relevant environ-
mental protection laws.
<
If the brake fluid level is too low and brake
pedal travel distinctly longer than usual,
one of the two hydraulic brake circuits may
have failed.
Visit your nearest BMW Service.
Increased brake pedal pressure
may be necessary and significantly longer
braking distances may be required. Modify
your driving style accordingly.
