Checking coolant level
Correct coolant level with the engine cold,
approx. +68 7/206:
1. Turn the cap of the expansion tank
counterclockwise to allow any accumu-
lated pressure to escape, then continue
turning to open
2. The coolant level is correct when the
coolant extends to between the MIN
and MAX marks on the filler neck, refer
to the diagram adjacent to the filler
neck
3. If the coolant is low, slowly add coolant
up to the specified level – do not overfill.
Brake fluid
The symbol lights up and a mes-
sage appears on the Control Dis-
play: the brake-fluid level in the
container is too low.
The brake fluid reservoir is located under
the microfilter housing trim panel on the
driver's side of the vehicle. To have brake
fluid added to the system, or to have the
source of any brake fluid loss traced and
rectified, please contact your BMW center,
which can also supply the factory-
approved – DOT 4 – brake fluids.
Brake fluid is hygroscopic: it absorbs
moisture from the atmosphere over
the course of time.
To ensure that the brake system continues
to provide safe and reliable performance,
remember to have the brake fluid changed
every 2 years at the latest, refer to page
66
and to the Service and Warranty Informa-
tion Booklet for US models or the Warranty
and Service Guide Booklet for Canadian
models.
Brake fluid is toxic and also damages vehi-
cle paintwork. Always store these agents in
tightly-closed original containers kept well
away from the reach of children.
Do not spill the fluid and do not refill the
brake fluid reservoir to beyond the MAX
mark. Should it come into contact with hot
engine components, the brake fluid could
ignite and cause personal injury in the form
of burns.

Always observe all applicable rules
and regulations for environmental
protection when disposing of used brake
fluid.

Brake hydraulic systems
A low brake-fluid level combined with
longer-than-usual pedal travel could be a
sign that one of the brake system's hydrau-
lic circuits has failed.
Proceed to the nearest BMW center.
Remember that pedal travel may be
increased, and there may also be a sub-
stantial increase in the amount of pedal
pressure required to brake the vehicle.
Please adapt your driving style accord-
ingly.
