2008 BMW M3 tow bar

Technology for driving comfort and safety
82 until "PDC" is selected and press the con-
troller.
6.Select "PDC display on" and press the con-
troller.
The PDC screen is activated.
The display is shown on the Control Display as
soon as PDC is activated.
System limitations
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are pro-
vided, there is a blind spot in which objects can
no longer be detected. The system is also sub-
ject to the physical limits that apply to all forms
of ultrasonic measurement, such as those
encountered with trailer towbars and hitches,
thin or wedge-shaped objects, etc. Low objects
that have already been displayed, e. g. curbs,
can disappear again from the detection area of
the sensors before or after a continuous tone
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected. Therefore, always drive
cautiously, otherwise there is a risk of personal
injury or property damage. Loud sound sources
outside or inside the car can drown out the PDC
signal. Therefore, always drive cautiously, oth-
erwise there is a risk of personal injury or prop-
erty damage.<
Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.
Antilock Brake System ABS
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
The ABS is operational every time you start the
engine. Braking safely, refer to page115.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Brake assist
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressure on the brake for the
duration of the full braking application.
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 limits 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The laws of physics cannot be repealed,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 not reduce the additional
safety margin again by taking risks, as this could
result in an accident.<
M Dynamic Mode MDM*
M Dynamic Mode is a mode of the Dynamic
Stability Control DSC that permits greater lon-
gitudinal and lateral acceleration when driving
on dry surfaces, yet with reduced driving stabil-
ity. 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

headlamps, tail lamps, turn signal indicators and
windshield wipers may be unavailable.
Power steering assistance is not available when
the engine is not running. Thus, braking and
steering will require increased effort.<
Manual transmission
Gearshift lever in neutral position.
M dual clutch transmission with
Drivelogic
Ensure that the parking lock P is not
engaged as the rear wheels will otherwise
be blocked.
When using the car wash function, refer to
page56, note that the parking lock P is
engaged automatically after approx. 30 min-
utes, blocking the rear wheels.
If an electrical malfunction occurs or if towing
takes longer than approx. 20 minutes, manually
release the parking lock, refer to page59.<
When towing, do not exceed a maximum
speed of 30 mph/50 km/h and a maxi-
mum distance of 30 miles/50 km, otherwise the
transmission can be damaged.<
BMW recommends transporting the vehicle on
a tow truck with a flat bed.
Towing methods
Do not lift the vehicle by a tow fitting or
body and chassis parts, otherwise dam-
age may result.<
With a tow bar
The towing vehicle must not be lighter
than the towed vehicle, otherwise it may
be impossible to maintain control.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an angle,
please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
>The tow bar will generate lateral forces if it is
attached offset.Attach the tow bar to the tow fittings only,
as attaching it to other parts of the vehicle
could result in damage.<
With a tow rope
When starting off in the towing vehicle, make
sure that the tow rope is taut.
To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Attach the tow rope to the tow fittings only, as
attaching it to other parts of the vehicle could
result in damage.<
With a tow truck
Manual transmission:
Have the BMW transported with a tow truck
with a so-called lift bar or on a flat bed.
Do not tow the vehicle with just the rear axle
raised as this may cause the steering to turn.
M dual clutch transmission:
Have the BMW transported with a tow truck
with a so-called lift bar or on a flat bed.
Tow-starting
If possible, do not tow-start the vehicle but
jump-start the engine, refer to page231. Vehi-

Giving and receiving assistance
234 cles with a catalytic converter should only be
tow-started when the engine is cold.
Manual transmission
1.Switch on hazard warning flashers, comply
with local regulations.
2.Switch on the ignition, refer to page54.
3.Shift into 3rd gear.
4.Have the vehicle tow-started with the clutch
depressed and slowly release the clutch.
After the engine starts, immediately
depress the clutch completely again.
5.Stop at a suitable location, remove the tow
bar or rope and switch off the hazard warn-
ing flashers.
6.Have the vehicle checked.
M dual clutch transmission with
Drivelogic
Vehicles with an M dual clutch transmission
cannot be tow-started. Jump-starting, refer to
page231.
