Brake system Winter operation Brake fluid level
The warning lamp for the brake
hydraulic system comes on, or
the CHECK BRAKE FLUID mes-
sage appears in the Check Con-
trol
*.
The brake fluid level is too low in the
reservoir (refer to page 141).
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 autho-
rized BMW center. Higher brake
application 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 also comes on when
the CHECK BRAKE LININGS message
appears in the Check Control.
Brake pads
The warning lamp for the brake
pads comes on, or the CHECK
BRAKE LININGS message ap-
pears in the Check Control
*:
The brake pads have reached their min-
imum pad thickness. Proceed to the
nearest authorized BMW center as
soon as possible to have the pads re-
placed.
For your own safety: use only
brake pads that BMW has re-
leased for your particular vehicle
model. BMW cannot evaluate non-ap-
proved brake pads to determine if they
are suited for use, and therefore cannot
ensure the operating safety of the vehi-
cle if they are installed.<
The onset of winter is often accompa-
nied by rapid changes in weather. Ad-
aptations in driving style should be
accompanied by preparations on the
vehicle itself to ensure that your
progress through the winter remains
safe and trouble-free. Coolant Be sure that the coolant mixture
contains the year-round ratio of 50:50
water and antifreeze/corrosion protec-
tion. This mixture provides protection
against freezing down to approx. -347
(-376). Replace the coolant every four
years. Locks BMW door lock deicer can be used to
free locks if they are frozen. This deicer
also contains lubricant.
After using the deicer, treatment with
BMW lock barrel grease is recom-
mended.
