Brake system
Brake fluid level
If the brake fluid level is too low and 
brake pedal travel has become longer, 
there may be a defect in one of the 
brake system's hydraulic circuits.
Proceed to the nearest autho-
rized BMW center. It may be nec-
essary to apply higher levels of pres-
sure to the pedal when stopping and 
braking distances may also be longer. 
Please remember to adapt your driving 
style accordingly.

Disc brakes
Limited vehicle use, extended periods 
with the vehicle parked or in storage, 
and operating conditions in which brak-
ing is restricted to gentle, low-pressure 
applications will all increase the ten-
dency for corrosion to form on the 
rotors; this is often accompanied by a 
simultaneous accumulation of contami-
nation on the brake pads. The pads 
must exert a certain minimal level of 
pressure against the rotors for the disc 
brakes' inherent self-cleaning effect to 
remain effective.
If the brake rotors are corroded, they 
will tend to respond to braking with a 
pulsating effect that even extended 
brake applications will fail to cure.
When driving in heavy rain and on wet 
roads it is useful to apply light pressure 
to the brake pedal every few miles. 
Monitor traffic conditions to ensure that 
this maneuver does not pose a hazard 
to you or to other road users. The heat 
generated in this process helps dry the 
pads and rotors to ensure that your 
brake system will respond with undi-
minished efficiency when you need it.
When descending steep hills and 
extended grades, downshift to a gear 
that will allow you to continue safely 
with only a minimal amount of braking. 
By minimizing the loads placed on the 
brake system, this strategy helps 
ensure that optimal brake system 
response will remain available at all 
times. Use care to avoid exceeding the 
approved engine-speed range, refer to 
page 
Do not coast with the clutch 
depressed or with the transmis-
sion or selector lever in Neutral. Do not 
coast with the engine shut off. The 
engine provides no braking effect when 
the clutch is depressed and there is no 
power-assist for braking or steering 
when the engine is not running.
Never allow floor mats, carpets or any 
other objects to protrude into the area 
around the accelerator, clutch and 
brake pedals and obstruct their move-
ment.

Brake pads
For your own safety: use only 
brake pads that BMW has 
released for your particular vehicle 
model. BMW cannot evaluate non-
approved brake pads to determine if 
they are suitable for use, and therefore 
cannot ensure the operating safety of 
the vehicle if they are installed.

Portable phone in the vehicle
BMW recommends using mobile com-
munications devices, e.g. portable 
phones, inside the vehicle with a suit-
able outside antenna. Otherwise, it can-
not be ruled out that the vehicle elec-
tronics and portable phone may 
interfere with each other.
