2006 BMW 650I COUPE brake light

Driving
72 your vehicle when there is a slow-moving vehi-
cle, stopped vehicle or stationary object ahead
of you, as for example at a traffic light or when
approaching a parked vehicle. Also, the system
does not react to oncoming traffic, pedestrians
or other types of potential traffic such as a rider
on horseback. It is also possible that the system
may not detect smaller moving objects such as
motorcycles or bicycles. Be especially alert
when encountering any of these situations as
the system will neither automatically brake, nor
provide a warning to you. Also, be aware that
every decrease in the distance setting allows
your vehicle to come closer to a vehicle in front
of you and requires a heightened amount of
alertness.<
If your vehicle is actively following a vehicle in
front of you and the vehicle ahead speeds up or
the lane ahead becomes clear, then your vehi-
cle will accelerate to the speed you have
selected. Be aware that changing to a clear,
unobstructed lane will also result in your vehicle
accelerating.
Be certain to deactivate the system when
you pull into an exit lane for a highway off-
ramp.<
Also, vehicles traveling in a staggered manner
on a highway may cause a delay in the system's
reaction to a vehicle in front of you or may cause
the system to react to a vehicle actually in the
lane next to you. Always be ready to take action
or apply the brakes if necessary.
Active cruise control can only decelerate the
vehicle to approx. 20 mph/30 km/h. If the sys-
tem reduces vehicle speed below 20 mph/
30 km/h or if DSC/ABS is engaged while driving,
the system will automatically deactivate.
Remember, the system cannot stop your
vehicle. In addition, the system is deacti-
vated whenever the driver applies the vehicle
brakes, shifts into neutral, or deactivates DSC.
After any deactivation, the system will no longer
automatically activate the vehicle brakes, which
means the driver must intervene and resume
manual braking. You should then reactivate the
system only when you are fully aware of the
prior speed and distance settings. reduce the stored desired speed; however, the
driver must constantly monitor traffic and inter-
vene if necessary.
When you switch off the engine or ignition,
active cruise control is fully switched off, too,
and any settings you have selected are can-
celed.
Swerving vehicles
When a vehicle moves from an adjacent lane
into your lane, active cruise control will not rec-
ognize this vehicle until it is fully in your lane
ahead of your vehicle.
Behavior in curves
Because of the limited range of the system, it is
possible that in curves or on the peaks and val-
leys of hilly roads, a vehicle ahead may be rec-
ognized late, or not at all. Therefore, it is up to
the driver to select a speed that is prudent in
view of the curves and terrain of the roadway.

The DSC is operational every time you start the
engine.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Do not reduce the additional safety mar-
gin of the system by taking risks.<
Deactivating DSC
Press the button until the DSC indicator lamp in
the instrument cluster lights up, but not for
longer than approx. 10 seconds. DTC Dynamic
Traction Control and DSC are deactivated
together. Interventions promoting stability and
forward momentum will no longer be carried
out. The stability-promoting intervention of the
active steering
* is also deactivated, refer to
page90.
A message appears on the Control Display.
Please note any supplementary information
that appears there.
To support enhanced operating stability, reacti-
vate DSC again as soon as possible.
Activating DSC
Press the button; the indicator lamp in the
instrument cluster goes out.
For better control
The indicator lamp flashes:
DSC is controlling the drive forces and
brake forces.
The indicator lamp comes on:
DSC is deactivated.
DTC Dynamic Traction Control
DTC is a variant of DSC for special road condi-
tions, e.g. uncleared snow-covered roads, that
is optimized for forward momentum. The sys-
tem ensures maximum forward momentum, but
with limited driving stability. Therefore, drive
with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
>When driving on snowy inclines, in slush, or
on unplowed, snow-covered road surfaces
>When rocking a stuck vehicle free or when
starting off in deep snow or on loose ground
>When driving with snow chains
*
Activating DTC
Press the button; the DTC indicator lamp in the
instrument cluster lights up.
Deactivating DTC
Press the button again; the DTC indicator lamp
in the instrument cluster goes out.
For better control
The indicator lamp flashes:
DSC is controlling the drive forces and
brake forces.
The indicator lamp comes on:
DTC is activated.

Active steering*
The concept
The active steering is a system that actively var-
ies the steering angle of the front wheels in rela-
tion to the steering wheel movements.
At low speeds, e.g. in a town or when parking,
the steering angle of the wheels is increased,
i.e. the steering becomes very direct.
In the higher speed range, on the other hand,
the steering angle is reduced more and more.
This improves the handling capability of your
BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stability-pro-
moting intervention is deactivated when DSC is
switched off, refer to page86.
Malfunction
The warning lamp lights up and a mes-
sage appears on the Control Display. The active steering is no longer operational. At
low speed, larger steering wheel movements
are required, while the vehicle reacts more sen-
sitively to steering wheel movements in the
higher road speed range. The stability-promot-
ing intervention can also be deactivated. Pro-
ceed cautiously and drive defensively. Have the
system checked.

Mobile communications devices in
vehicle
BMW advises against using mobile com-
munications devices, e.g. mobile phones,
inside the vehicle without a direct connection
to an external antenna. Otherwise, the vehicle
electronics and mobile communications device
can interfere with one another. In addition, there
is no assurance that the radiation emitted dur-
ing transmission will be conveyed out of the
vehicle interior.<
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 phenomenon is referred to as hydro-
planing, and is characterized by a partial or
complete loss of contact between the tires and
the road surface, ultimately undermining your
ability to steer and brake the vehicle.<
The risk of hydroplaning increases as the tread
depth of the tires decreases, also refer to Mini-
mum tire tread on page187.
Driving through water
Do not drive through water on the road if
it is deeper than 1 ft/30 cm, and then only
at walking speed at the most. Otherwise, the
vehicle's engine, electrical systems and trans-
mission may be damaged.<
Using handbrake on inclines
On inclines, do not hold the vehicle with
the clutch; use the handbrake. Otherwise
greater clutch wear will result.<
SMG Sequential Manual Gearbox
Start off quickly on slopes. Do not hold
the vehicle on a hill by applying the throt-
tle, but engage the handbrake instead. Other-
wise overheating can occur in the transmission
region.<
Starting assistant
The starting assistant enables you to start off
conveniently on slopes. The parking brake is
not required for this purpose.
1.Hold the vehicle with the footbrake.
2.Release the footbrake and immediately
drive off quickly.
The starting assistant holds the vehicle
for approx. 2 seconds after releasing the
footbrake. Depending on the load, the vehicle
may also roll back slightly during this time.
After releasing the footbrake, immediately start
quickly; otherwise, the starting assistant no
longer holds the vehicle after approx. 2 seconds
and it begins to roll back.<
Braking safely
Your BMW is equipped with ABS as a standard
feature. In situations that require it, it is best to
brake with full force. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indicate to
the driver that ABS is in its active mode.
Do not drive with your foot resting on the
brake pedal. Even light but consistent
pedal pressure can lead to high temperatures,
brake wear and possibly even brake failure.<
Driving in wet conditions
When driving on wet roads or in heavy rain, it is
a good idea to apply light pressure to the brake
pedal every few miles. Monitor traffic conditions
to ensure that this maneuver does not endan-
ger 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 thus reduced
efficiency of the brake system, downshift
to a gear in which only minimal brake applica-
tions are needed when descending long or

Things to remember when driving
116 steep downhill stretches. Even light but consis-
tent pedal pressure can lead to high tempera-
tures, brake wear and possibly even brake fail-
ure.<
The braking action of the engine can be further
increased by downshifting in the manual mode
of the automatic transmission, possibly as far as
first gear, refer to page63. This prevents an
excessive load on the brakes.
Do not drive with the clutch depressed, in
idle or with the engine switched off; other-
wise, there will be no engine braking action or
power-assisted braking and steering.
Never allow floor mats, carpets or any other
objects to protrude into the area of movement
of the pedals and impair their operation.<
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
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
When vehicle is parked
Condensation forms in the automatic climate
control during operation, and then exits under
the vehicle. Traces of condensed water under
the vehicle are therefore normal.
Before driving into a car wash
To prevent the exterior mirrors on this vehicle
from being damaged, always fold them in by
hand before entering an automatic car wash.
With comfort access and automatic
transmission
Insert the remote control into the ignition lock.
The engine can be switched off in the selector
lever position N. Also refer to page37.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. The ultimate result
can assume the form of a sudden blow-out.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX lbs. or YYY kg, otherwise the vehicle
may be damaged and unstable driving con-
ditions may result.<
2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3.Subtract the combined weight of the driver
and passengers from XXX lbs. or YYY kg.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the XXX amount equals
800 lbs. and there will be four 150-lb. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
200 lbs.:
800 lbs. minus 600 lbs. = 200 lbs.

Do not use oil additives; under some
circumstances, they can harm your
engine.<
Viscosity grades
The viscosity is a measure of the thickness of
the oil and is specified in SAE grades.
The choice of the right SAE grade is based on
the climatic conditions in the region in which
you normally drive your BMW.
Approved oils belong to the SAE grades
5W-40 and 5W-30.<
These oils can be used for driving at all outside
temperatures.
Coolant
Do not open the cooling system when the
engine is hot. Escaping coolant can cause
burns.<
Coolant consists of water and coolant additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW center for
suitable additives.
Only use suitable additives; otherwise,
engine damage may result. The additives
present a health hazard.<
Always observe all applicable environ-
mental laws and regulations when dis-
posing of used coolant additives.<
Checking coolant level
1.The engine must be at ambient tempera-
ture.
2.Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-
sure to escape, then continue turning to
open.
3.The coolant level is correct when it lies
between the Min and Max mark, also refer to
the drawing next the filler neck.
4.If the coolant is low, slowly add coolant up to
the specified level – do not overfill.
5.Turn the cap until it clicks.
6.Have the reason for the coolant loss elimi-
nated as soon as possible.

brake pedal path can be necessary, and
significantly longer braking distances may be
required. Please adapt your driving style
accordingly.<
Brake pads
The warning lamp lights up in red
in spite of the handbrake being
released; a message appears on the
Control Display.
The brake pads have reached their minimum
pad thickness. Have the brake pads replaced as
soon as possible.
Warning lamp for Canadian models.
For your own safety: use only brake pads
that BMW has approved for your particu-
lar vehicle model. As BMW cannot assess the
suitability of other brake pads for use on your
vehicle, BMW is unable to assume continued
responsibility for the vehicle's operating safety
if non-approved pads are installed.<
