Vehicle equipment
In this chapter, all production, country, and
optional equipment that is offered in the model
range is described. For this reason, descrip-
tions will be given of some equipment that may
not be available in a vehi
cle, for example due to
the special options or national-market version
selected. This also app lies to safety related
functions and systems.
Driving stability control
systems
Contrary to the descript ion in the Owner's Man-
ual for Vehicle, your BMW 1-Series M Coupe is
not equipped with Dyna mic Traction Control
DTC.
Dynamic Stability Control DSC
DSC optimizes driving stability and traction. In
addition, the system recognizes unstable driv-
ing situations such as understeering and over-
steering, and helps keep the vehicle on a safe
course within physical lim its by reducing engine
power and applying the brakes on individual
wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Therefore, do no t reduce the additional
s a f e t y m a r g i n a g a i n b y t a k i n g r i s k s , a s t h i s c o u l d
result in an accident.<
M Dynamic Mode MDM
M Dynamic Mode is a mode of the Dynamic
Stability Control DSC that permits greater
longitudinal and latera l acceleration when
driving on dry surfaces, yet with reduced driving
stability. Only at the absolute limit of stability
does the system intervene to stabilize the vehicle by reducing engine power and applying
the brakes on the wheels. In such situations,
additional corrective steering maneuvers may
be necessary.
M Dynamic Mode is switched off every time the
engine is started.
When the M Dynamic Mode is on, stabi-
lizing measures are pe rformed to a limited
degree only. Take acti on yourself, otherwise
there is a risk of an accident. <
To maintain vehicle stability, drive with
the DSC activated and the
M Dynamic Mode deactivated whenever possi-
ble. <
Activating MDM
Push the button: the indicator lamps for MDM
and DSC OFF light up.
For better control
The indicator lamps MDM and
DSC OFF light up and the indicator
lamp DSC flashes:
M Dynamic Mode is controlling the
drive and braking forces.
The indicator lamp DSC lights up: DSC
and M Dynamic Mode have failed.

Vehicle equipment
In this chapter, all pr oduction, country, and
optional equipment that is offered in the model
range is described. As a result, some equip-
ment described may not be available in a
particular vehicle, for example due to the
options or national-market version selected.
This also applies to safe ty related functions and
systems.
Break-in period
Note the following instructions for your
BMW 1-Series M Coupe that deviate from the
description in the Owner's Manual for Vehicle.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at varying engine and road speeds, but do
not exceed an engine speed of 5,500 rpm and a
road speed of 105 mph/170 km/h.
Do not depress the ac celerator all the way.
From 1,200 miles/2,000 km to
3,000 miles/5,000 km
Engine and road speeds can be increased
gradually up to a traveling speed of 135 mph/
220 km/h. Use the maximum speed only for
brief intervals, e. g. when passing.
Transmission
The transmission begins functioning at an
optimal level only after a distance of approx.
300 miles/500 km. Do not exceed engine
speeds of 5,500 rpm during this period.
General driving notes
Clearance
Take into account the limited clearance of
your BMW 1-Series M Coupe, e. g. when
driving into underground parking garages or
over obstacles. Otherwise, the vehicle may be
damaged. <
Braking safely
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least br aking is required. Even
light but consistent brak e pressure can lead to
high temperatures, brake wear and possibly
even brake failure. <
You can increase the engine's braking effect by
shifting down, all the way to first gear if neces-
sary. This strategy helps you avoid placing
excessive loads on the brake system.
Never drive with the clutch held down,
with the transmission in neutral or with
the engine switched off; otherwise, engine
braking action will not be present or there will be
no power assistance to the brakes or steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
pedals; otherwise, pedal function could be
impaired. <
