Winter operation
Brake fluid level
The warning lamp for the brake
hydraulic system comes on or
the message "Check Brake
Fluid" appears in the Check
Control:
The brake fluid level is too low in the
reservoir. Refer to page
147
.
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 cir-
cuits.
The remaining circuit continues to pro-
vide adequate brake-system perfor-
mance.
Proceed to the nearest authorized
BMW center. Higher brake appli-
cation pressure may be necessary un-
der these conditions, and brake pedal
travel may be significantly longer.
Please remember to adapt your driving
style accordingly.

The warning lamp also comes on with
the "Check Brake Pads" message in the
Check Control.
Brake pads
The message "Check Brake Pads" 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.
We recommend the use of original
BMW brake pads and compo-
nents, otherwise driving safety can be
impaired.

The onset of winter is often accompa-
nied by rapid changes in weather. Ad-
aptations in driving style should be ac-
companied by preparations on the
vehicle itself to ensure that your vehicle
operation through the winter remains
safe and trouble-free.
Coolant
Be sure that the coolant mixture is kept
at the year-round ratio of 50:50 (water
and antifreeze/corrosion protection).
This mixture provides protection
against freezing down to approx. –34
7
(–37
6
). Replace the coolant every four
years.
Locks
BMW 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.
