2008 BMW M3 SEDAN brake light

Driving
66 On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If engine braking power is
insufficient on a downhill grade, the stored
speed may be exceeded.
Increasing desired speed
Repeatedly press the lever to the resistance
point or beyond, arrow1, until the desired
speed is reached.
>Each time the lever is pressed lightly to the
resistance point, the desired speed is
increased by approx. 1 mph or 1 km/h.
>Each time the lever is pressed beyond the
resistance point, the desired speed is
increased by up to 5 mph or 10 km/h.
The system stores and maintains the speed.
Accelerating using the lever
Accelerate slightly, increase speed steadily:
Press the lever to the resistance point, arrow 1,
until the desired speed is reached.
Accelerate strongly, increase speed in intervals
of 10:
Press the lever beyond the resistance point,
arrow 1, until the desired speed is reached.
The vehicle accelerates without pressure on
the accelerator pedal. The system stores and
maintains the speed.
Decreasing speed
Repeatedly pull the lever to the resistance point
or beyond, arrow 2, until the desired speed is
displayed.
>Each time the lever is pulled to the resis-
tance point, the desired speed is decreased
by approx. 1 mph or 1 km/h.
>Each time the lever is pulled beyond the
resistance point, the desired speed is
reduced by up to 5 mph or 10 km/h until the
minimum speed of 20 mph or 30 km/h is
achieved.
The system stores and maintains the speed.
Deactivating cruise control
Tap the lever upwards or downwards, arrow3.
The displays on the speedometer disappear.
In addition, the system is automatically deacti-
vated:
>When you brake the vehicle
>When you shift or depress the clutch
>When you deactivate DSC
>When DSC or ABS is intervening
Cruise control is not deactivated by depressing
the accelerator pedal. Once the accelerator
pedal is released, the stored speed is achieved
again and maintained.
Resuming a speed stored beforehand
Press the button, arrow4.
The stored speed is resumed and maintained.
When the ignition is switched off, the stored
speed value is cleared and can no longer be
called up.

For better control
If the indicator lamp flashes:
DSC is regulating the drive and brak-
ing forces.
If the indicator lamps are on:
DSC is deactivated.
Electronic Damper Control
EDC*
The concept
Whenever there is a change in any significant
parameter such as road surface quality or in an
operating condition such as steering, braking,
etc., the damping automatically adjusts to the
new conditions in fractions of a second.
You can select between three programs.
"Comfort" program
Select the "Comfort" program if you want com-
fort-oriented control of the shock absorbers.
"Normal" program
The "Normal" program offers control that is bal-
anced between comfort and sportiness.
"Sport" program
Select the "Sport" program if you want consis-
tently sporty control of the shock absorbers.
Selecting a program
Press the EDC button repeatedly:
>"Comfort": LED off:
>"Normal": one LED lights up.>"Sport": both LEDs light up.
Each time the engine is started, the program set
for the remote control in use is active, refer to
Key-dependent settings on page49.
You can also set and call up your preferred
program via MDrive, refer to page48.
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.<
Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor detects pressure loss in a
tire by comparing the rotating speeds of the
individual tires while moving.
In the event of pressure loss, the rolling circum-
ference changes and, thus, the rotating speed
of the affected wheel. This change is detected
and is reported as a flat tire.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
The system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<

ing, take care to avoid possible contact
between the hot exhaust system and any highly
flammable materials such as hay, leaves, grass,
etc. Such contact could lead to a fire, with the
risk of serious personal injuries and property
damage. Do not touch hot exhaust pipes, e. g.
when loading the cargo bay, otherwise there is a
risk of burn injuries.<
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This situation, known as hydroplaning,
means that the tire can completely lose contact
with the road surface, so that neither the car can
be steered nor the brake be properly applied.<
The risk of hydroplaning increases with declin-
ing tread depth on the tires, refer also to Mini-
mum tread depth on page209.
Driving through water
Drive through water on the road only if it is
not deeper than 1 ft/30 cm, and then only
at walking speed at the most. Otherwise, the
vehicle's engine, the electrical systems and the
transmission may be damaged.<
Use the parking brake on inclines
On inclines, do not hold the vehicle for a
lengthy period using the clutch; use the
parking brake instead. Otherwise greater clutch
wear will result.<
For more information about the drive-off assis-
tant, refer to page84.
Braking safely
Your BMW is equipped with ABS as a standard
feature. Applying the brakes fully is the most
effective way of braking in situations in which
this is necessary. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.
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 braking is required. Even
light but consistent brake 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.
M dual clutch transmission: never drive
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.
Manual transmission: never drive with the
clutch held down, with the transmission in neu-
tral 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.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads

BMW M3 engineering
High performance V8 engine
The high-revving V8 engine draws a maximum
power of 420 hp/309 kW and a peak torque of
295 lb ft/400 Nm from a displacement of
244 cu in/4 liters. Its spontaneous response
results in a very wide effective rpm range. The
maximum engine speed lies at 8,400 rpm and is
electronically controlled. Due to the high engine
dynamics, the maximum engine speed is lim-
ited to 7,000 rpm when the vehicle is standing.
Warming up the engine
During the warm-up phase, the high-perfor-
mance V8 engine runs a little more roughly due
to its emissions control system.
For technical reasons, the exhaust system
sounds slightly metallic when the engine is
cold.
For further information on warming up the
engine, refer to Tachometer on page67 and
Engine oil temperature on page68.
Compound brake
Your BMW M3 is equipped with a high-perfor-
mance brake system with perforated com-
pound brake discs.
Due to special design features of the perforated
compound brake discs, operating noise is audi-
ble during braking. However, this does not
affect the brake's performance, safe operation
or stability under load.
Braking correctly
To keep the brake system in optimal condition,
it is advisable to apply the brakes at regular
intervals as appropriate for the character of the
vehicle.
Refer also to Corrosion on brake rotors on
page115.
Drive train
In your BMW M3, special emphasis was placed
on the direct connection between the engine
and drive. The torsionally rigid execution of the
drive train results in acoustic feedback of the
torque, as is typical in sports cars. Clacking
sounds can arise during load changes. They do
not impair functionality or shorten the lifespan
of any component.
