of you, for example when approaching a traffic
light or 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.<
When your vehicle is actively following a vehicle
in front of you, if 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 may also result in accelera-
tion of your vehicle.
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 the transmission from drive/D to
neutral/N, or deactivates DSC. After any deacti-
vation, the system will no longer automatically
activate the vehicle brakes, which means the
driver must intervene and resume manual brak-
ing. 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
detect 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.

Technology for comfort, convenience and safety
88 as fishtailing or sliding of the vehicle's front
wheels. In these cases, DSC helps the vehicle
safely stay on course within the physical limits
by reducing the engine output and by applying
the brakes in the individual wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Do not squander your added margin of
safety by driving dangerously; otherwise you
run the risk of causing an accident.<
Deactivating DSC
1.Press the button to open the start
menu.
2.Move the controller toward "Settings".
3.Select "DTC" and press the controller for at
least 3 seconds.
The LED for "DTC" and the DSC indicator lamp
on the Info Display light up. DTC Dynamic Trac-
tion Control and DSC Dynamic Stability Control
are deactivated together. Interventions promot-
ing stability and forward momentum will no
longer be carried out.
To promote enhanced operating stability, reac-
tivate DSC again as soon as possible.
Activating DSC
Select "DTC" and press the controller.
The LED on the Control Display and the DSC
indicator lamp on the Info Display go out.
For control purposes
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 version of DSC that is optimized for
forward momentum in special road conditions.
The system 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 snow-covered uphill
grades, in slushy snow or on uncleared,
snow-covered roads
>When rocking a stuck vehicle free or when
starting off in deep snow or on loose ground
>When driving with snow chains
Activating DTC
iDrive, for principle details, refer to page16.
1.Press the button to open the start
menu.
2.Move the controller toward "Settings".
3.Select "DTC" and press the controller.
The LED for "DTC" and the DTC indicator lamp
on the Info Display light up.
For control purposes
The indicator lamp flashes:
DTC is controlling the drive forces and
brake forces.
The indicator lamp comes on:
DTC is activated.

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 tires and
road surface, ultimately undermining your abil-
ity to steer and brake the vehicle.<
Driving through water
Only drive through water with a maximum
depth of 1 ft/30 cm and then, at no more
than walking speed. Otherwise, you run the risk
of damaging the vehicle's engine, electrical sys-
tems, and transmission.<
Safe braking
Your BMW is equipped with ABS as standard
equipment. In situations that require it, it is best
to apply the brakes fully. Since the vehicle
maintains steering responsiveness, you can
nevertheless 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.
Driving in wet conditions
When driving in wet conditions and 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 endanger other road users. The heat gener-
ated 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 reduced effi-
ciency of the brake system, drive long or
steep downhill grades in the gear that requires
the least amount of braking. Otherwise, even
light but consistent pedal pressure can lead to
high temperatures, brake wear, and possibly
even failure of the brake system. action by selecting a lower gear in the automatic
transmission's manual mode, downshifting as
far as first gear on extremely steep stretches,
refer to page63. This strategy helps you avoid
placing excessive loads on the brake system.
Do not drive in idle or with the engine
switched off; otherwise, there will be no
engine braking action or power-assist for the
brakes 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 minimal
pressure that must be exerted by the pads dur-
ing 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
1.Fold in the exterior mirrors, refer to page50;
otherwise, they could be damaged due to
the width of the vehicle.
To permit the vehicle to roll, follow the
instructions on page58.
2.Release the parking brake, especially when
you have activated Automatic Hold. Refer to
page59.
