Mirrors
Exterior mirrors
The mirror on the passenger's side is
more curved than the driver's mirror.
Objects reflected in the mirror are closer than
they appear. Do not estimate the distance of
following traffic based on what you see in the
mirrors, otherwise there is an increased acci-
dent risk.<

You can also adjust the mirrors manually by
pressing against the outer edges of their mirror
glass.
Folding mirrors in and out*
Pressing button3 allows you to fold mirrors
in and out up to a speed of approx. 20 mph/
30 km/h. This is advantageous, for example, in
car washes, narrow streets or for bringing mir-
r o rs t h a t h a v e b e e n m a n u a l ly f o l d e d in b a c k i n t o
the correct position. Mirrors that were folded in
are folded out automatically at a speed of
approx. 25 mph/40 km/h.
Before going through a car wash, fold the
mirrors in manually, or with button 3, oth-
erwise they could be damaged, depending on
the width of the car wash system.<
Automatic heating
Below a certain outdoor temperature, both
exterior mirrors are heated whenever the
engine is running or the ignition is switched on.

2Cleaning the rear window
Do not use washing mechanisms when
the washer fluid reservoir is empty, other-
wise you will damage the washer pump.<
Washer fluid
Washer fluid antifreeze is flammable. For
this reason, keep it away from ignition
sources and store only in the closed original
container out of reach of children. Otherwise,
there is the danger of bodily injury. Always
observe the instructions for use provided on the
containers.<
Filler neck for washer fluid
Only add washer fluid with the engine
cooled down to exclude contact with hot
engine components. Otherwise there is a dan-
ger of fire and to personal safety if the fluid is
spilled. voir.
Fill with water and – if required – with a washer
antifreeze, according to manufacturer's recom-
mendations.
In order to maintain the mixture ratio, mix
the washer fluid before filling.<

Sports Wagon: approx. 5.3 US quarts/5 liters.
Cruise control*
The concept
The cruise control is available for use at speeds
of approx. 20 mph/30 km/h and higher. The
vehicle stores and maintains the speed that you
set using the lever mounted on the steering col-
umn. To maintain the specified speed, the sys-
tem brakes if the engine braking effect is not
sufficient on a downhill grade. Speed can drop
on uphill grades if the engine output is insuffi-
cient.
Do not use the cruise control under driv-
ing conditions that do not permit a con-
stant speed, e.g. when driving on winding
roads, in heavy traffic or in poor road conditions
such as snow, rain, ice, loose road surface, and
poor visibility. Otherwise you could loose con-
trol of the vehicle and cause an accident.<

Selecting distance
>Briefly press rocker switch downward:
Increase distance.
>Briefly press rocker switch upward:
Reduce distance.
The selected distance is displayed in the instru-
ment cluster.
Use good judgment to select the appro-
priate following distance, given road con-
ditions, traffic, applicable laws and State driving
recommendations for safe following distance.
Otherwise, a violation of the law or risk of an
accident could result.<
Interrupting cruise control
Press the lever upward or downward, and with
the vehicle stopped also depress the brake
pedal. The marking in the speedometer
changes color and the distance indicator goes
out.
In addition, the system is automatically inter-
rupted:
>when you apply the vehicle brakes
>when you shift the transmission
>when DTC is activated or DSC is deacti-
vated
>when DSC comes on
>when you apply the handbrake
>when you release the safety belt and open
the driver's door with the vehicle stopped
>when the system does not recognize any
objects for an extended period of time, e. g.
on infrequently traveled roads without a
shoulder or guard rails, or if the radar sensor
is covered with dirt, refer to page75
If the system is interrupted, then it is nec-
essary for the driver to actively intervene
by braking and steering. Otherwise, there is a
risk of an accident.<
Resuming stored desired speed and
distance
While driving
Press button4.
The displays appear in the instrument cluster. Distance 1, closest
Distance 2

90 1.Press the button.
This opens the start menu.
2.Press the controller to open the menu.
3.Turn the controller until "Settings" is
selected and press the controller.
4.Turn the controller until "Vehicle / Tires" is
selected and press the controller.
5.Change to upper field if necessary. Turn the
controller until "PDC" is selected and press
the controller.
6.Select "PDC display on" and press the con-
troller.
The PDC screen is activated.
The display appears on the Control Display as
soon as PDC is activated.
System limits
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 tow bars and trailer cou-
plings, or thin and wedge-shaped objects etc. Low objects already displayed, e. g. curbs, can
also disappear from the detection area of the
sensors again before or after a continuous tone
already sounds. Higher, protruding objects, e.g.
ledges, cannot be detected. For this reason,
drive with care; otherwise, there is a danger of
personal injury or property damage.
Loud sources of sound, inside and outside the
vehicle, could drown out the PDC signal tone.<
Driving stability control
systems
Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability under extreme conditions.
ABS Antilock Brake System
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 page136.
CBC Cornering Brake Control
When braking during curves or when braking
during a lane change, driving stability and steer-
ing response are improved further.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Brake assistant
When you apply the brakes rapidly, this system
produces maximum braking force boosting and
thus helps to achieve the shortest possible
braking distance during full braking maneuvers.
This system exploits all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.

Adaptive brake assistant*
In conjunction with the active cruise control
with the stop-and-go function, the adaptive
brake assistant ensures that the brake
responds even more quickly during braking
with the brake assistant.
DSC Dynamic Stability Control
DSC prevents traction loss in the driving wheels
when starting off and accelerating. The system
also identifies unstable driving conditions, such
as a loss of traction at the rear of the vehicle or
sliding of the vehicle in its front wheels. In these
cases, DSC helps the vehicle maintain a safe
course within physical limits by reducing engine
output and through braking actions in the indi-
vidual 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 restrict the additional
safety margin with a risky driving style, as other-
wise there is a risk of an accident.<
Deactivating DSC
Press the button until the DSC indicator lamp in
the instrument cluster lights up, but not longer
than approx. 10 seconds. DTC Dynamic Trac-
tion Control and DSC are deactivated together.
Stabilizing and drive output promoting actions
are no longer executed. In addition, the stability
promoting intervention of the active steering
*
is deactivated, refer to page98.
A message appears on the Control Display.
Please note any supplementary information
that appears there.To increase vehicle stability, activate 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 controls the drive forces and
brake forces.
The indicator lamp lights up:
DSC is deactivated.
DTC Dynamic Traction Control
DTC is a version of DSC in which the drive out-
put is optimized for particular road conditions,
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with
reduced driving stability. It is therefore neces-
sary to 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 start-
ing off in deep snow or on loose ground
>When driving with snow chains
*
Activating DTC
Press the button briefly; the DTC indicator lamp
in the instrument cluster lights up.
