Brake system Winter operationBrake fluid level
The warning lamp for the brake
hydraulic system comes on, or
the "CHECK BRAKE FLUID"
message appears in the Check
Control.
The brake fluid level is too low in the
reservoir (refer to page 152).
If the brake fluid level is too low and
brake pedal travel has become notice-
ably longer, there may be a defect in
one of the brake system's hydraulic
circuits.
Proceed to the nearest authorized
BMW center. Higher brake appli-
cation pressure may be necessary
under these conditions, and brake
pedal travel may be significantly longer.
Please remember to adapt your driving
style accordingly.<
The warning lamp comes on together
with the "CHECK BRAKE PADS" mes-
sage in the Check Control.
Brake pads
The warning lamp for the brake
pads comes on, or the "CHECK
BRAKE PADS" message ap-
pears in the Check Control:
The brake pads have reached their
minimum pad thickness. Proceed to the
nearest authorized BMW center as
soon as possible to have the pads
replaced.
For your own safety: Use only
brake pads that BMW has
approved for your specific vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<
The onset of winter is often accompa-
nied by rapid changes in weather.
Adaptations in driving style should be
accompanied by preparations on the
vehicle itself to ensure that your vehicle
operation through the winter remains
safe and trouble-free.CoolantEnsure that the coolant mixture con-
tains the year-round ratio of 50: 50 of
water and antifreeze/corrosion protec-
tion. This mixture provides protection
against freezing down to approx. -347
(-376). Replace the coolant every four
years.LocksBMW door lock deicer can be used to
free the locks if they are frozen. This
deicer also contains lubricant.
After using deicer, treatment with BMW
lock barrel grease is recommended.
