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The laws of physics cannot be repealed,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.

ControlsTechnology for driving comfort and safety
Deactivating MDM
Press the button again; the indicator lamps in
the instrument cluster go out.
Deactivating DSC
Press the button for at le ast 3 seconds until the
indicator lamp for DSC OFF lights up and DSC
OFF is displayed in the instrument cluster. DSC
and M Dynamic Mode are both deactivated.
Stabilizing and drive-output promoting actions
are no longer executed.
You may find it useful to briefly deactivate DSC
under the following exce ptional circumstances:
> When driving uphill on snow-covered roads,
in slush or on unplowed, snow-covered
roads
> When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
> When driving with snow chains
To increase vehicle stab ility, activate DSC again
as soon as possible.
Activating DSC
Press the button again; th e indicator lamp in the
instrument cluster goes out.
For better control
If the indicator lamp flashes: The DSC
controls the driving and braking forces.
If the indicator lamp lights up: DSC and
MDM have failed.
The indicator lamp lights up and
DSC OFF is displayed in the instrument
cluster: DSC is deactivated.
Drive-off assistant
The drive-off assistant enables you to drive off
smoothly on uphill gradients. It is not necessary
to use the parking brake for this.
1.Hold the car in place by depressing the
brake.
2. Release the brake and drive off without
delay.
The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake is released. Drive off without delay after
releasing the brake. Otherwise, the drive-off
assistant will no longer hold the car in place
after approx. 2 seconds and the car will start to
roll backwards. <
The indicator lamps MDM and
DSC OFF light up:
M Dynamic Mode is activated.

Vehicle equipment
In this chapter, all pr oduction, 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.
Observe the following when
refueling
Note the following instructions for your
BMW 1-Series M Coupe that deviate from the
description in the Owner's Manual for Vehicle.
Fuel tank capacity
Approx. 14 US gal/53 liters, including the
reserve capacity of 2.1 US gal/8 liters.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km; otherwise, engine functions are not
ensured and damage can occur. <
Fuel specifications
Never use fuels labeled at the fuel pump as
metal-containing.
Do not use leaded gasoline or gasoline
with metallic additives such as manga-
nese or iron; doing so can cause permanent
damage to the catalyti c converter and other
components. <
Do not fill the tank with E85, i.e. fuel con-
taining 85 X ethanol, nor with FlexFuel.
Otherwise, the engine and fuel supply system
will be damaged. <
Required fuel
Super premium gasoline/AKI 93
Always use this premium grade fuel to obtain
maximum fuel economy and performance.
The minimum approved fuel grade is AKI 91.
Do not use any gasoline below the speci-
fied minimum fuel grade. Otherwise, the
engine could be damaged. <
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among ga solines offered for sale
in the United States and Canada. Fuels contain-
ing up to and including 10 X ethanol or other
oxygenates with up to 2.8 X oxygen by weight,
that is, 15 X MTBE or 3 X methanol plus an
equivalent amount of coso lvent, will not void the
applicable warranties with respect to defects in
materials or workmanship.
The use of poor-quality fuels may result in
drivability, starting and stalling problems
especially under certain environmental condi-
tions such as high ambient temperature and
high altitude.
Should you encounter drivability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recogn ized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may also result in unscheduled maintenance. <
