BMW M3 SEDAN Owner's Manual page 309

You can increase the engine's braking effect by
shifting down, going all the way to first gear, if
needed.
Safety information
Warning
Light but consistent brake pressure can lead to
high temperatures, brakes wearing out and
possibly even brake failure. There is a risk of
accident. Avoid placing excessive stress on the
brake system.
Warning
In idle state or with the engine switched off,
safety functions, for instance engine braking ef‐
fect, braking assistance and steering assis‐
tance, may not be available. There is a risk of
accident. Do not attempt to drive in idle state or
with the engine switched off.
Brake disc corrosion
Corrosion on the brake discs and contamination
on the brake pads are increased by the following
circumstances:
▷ Low mileage.
▷ Extended periods when the vehicle is not
used at all.
▷ Infrequent use of the brakes.
▷ Aggressive, acidic, or alkaline cleaning
agents.
Corrosion buildup on the brake discs will cause a
pulsating effect on the brakes in their response -
generally this cannot be corrected.
Condensation water under the
parked vehicle
When using the automatic climate control, con‐
densation water develops and collects under‐
neath the vehicle.

Ground clearance
NOTICE
If the ground clearance is insufficient, e.g.,
curbs or underground garage entrances, con‐
tact with vehicle parts, e.g., spoiler, and the un‐
derbody may occur. There is a risk of damage
to property. Ensure that there is sufficient
ground clearance available.
M Driver's Package: driving in
the higher speed range
Warning
Damage to vehicle components can negatively
impact the driving performance at high speeds.
This includes, among other things, tires, under‐
carriage and parts for improving aerodynamics.
There is a risk of accident. Have damage cor‐
rected by a dealer's service center or another
qualified service center or repair shop. Do not
drive at high speeds until the damage is cor‐
rected.
Roof-mounted luggage
rack
General information
Roof racks are available as special accessories.
Safety information
Warning
When driving with a roof load, for instance with
roof-mounted luggage rack, the vehicle's cen‐
ter of gravity is higher, which increases the risk
of the vehicle tipping in critical driving situa‐
tions. There may be a risk of accident or risk of
damage to property. Do not deactivate DSC
