Technology that monitors itself
The indicator and warning lamps identified
by the
+ symbol are subjected to an oper-
ation check each time you switch on the
ignition or start the engine. They each light
up once for different periods of time.
When a malfunction occurs in a monitored
system, the corresponding lamp will either
fail to go out when the engine is started, or
it will come on again during normal driving.
Detailed information is provided on the
specified pages.

You can also adjust the height of the head
restraint electrically.
To prevent possible personal injury
and property damage, always ensure
that the area above the head restraints is
clear and unobstructed before extending
them upward.<
Side extensions adjustment
You can fold the side extensions on the
head restraint forward to increase lateral
support.
Safety belts
Fastening
Make sure you hear the latch plate engage
in the belt buckle. The warning lamp lights up after
driving a short distance until after
the driver and front passenger have
fastened their safety belts.
At the same time, an acoustic signal
sounds. The warning lamp also lights up
and a signal sounds if the driver or front
passenger removes the safety belt during
driving.
The warning lamp can light up and a
signal can sound if objects are laid on
the front passenger's seat.<
Releasing
1.Press the red button in the belt buckle
2.Hold the belt firmly
3.Guide the belt back into its reel.
The shoulder strap's anchorage point will
be in the correct position for seat occu-
pants of every build if the seat is correctly
adjusted, refer to page47.
The two rear safety belt buckles integrated
in the rear seat are for passengers sitting
on the left and right. The belt buckle
embossed with the word CENTER is
intended exclusively for use by passengers
riding in the center position.
Damage to safety belts
In the event of loads caused by acci-
dents or other damage: have the belt
system including the belt tensioner and any
child restraint systems replaced and the
anchorage points checked. Only have cor-
responding work carried out by a BMW
center or a workshop that uses personnel
trained in accordance with BMW require-
ments.<
Rear seats
When the rear center position is not
occupied, the latch on the safety belt
can be inserted in the slot between the
seat's upholstery and the backrest.<

Driving
76 The vehicle brake lamps will automatically
illuminate to signal a following driver to take
action. In addition, it may be necessary for
the vehicle to downshift to maintain the dis-
tance setting selected. If the vehicle ahead
speeds up or when the lane ahead
becomes clear, your vehicle will accelerate
to the speed you have selected by increas-
ing the throttle setting and shifting gears as
needed.
Active cruise control is not and must
not be used as a collision avoidance/
warning system.<
Since this active cruise control sys-
tem is a new technology and operates
differently from conventional cruise control
systems which you may be accustomed,
you are strongly urged to read all of the
pages relating to this system before use.
Pay special attention to the information
contained in the Things to know about
active cruise control section in this manual
beginning on page78.<

Adjust your desired speed to the traf-
fic conditions and remain ready to
brake at all times. Great differences in
speed to the vehicles driving ahead, e.g.
when quickly approaching a truck or when
another vehicle swerves into your lane,
cannot be compensated for by the sys-
tem.<
Activate system
From approx. 20 mph/30 km/h you can
activate the system by pressing the lever
forward or pulling it back:
The current driving speed is stored as a
desired speed and briefly displayed in the
speedometer, refer to arrow.
If the display ACC --- mph/km/h
appears briefly in the speedometer,
it might be that conditions necessary for
operation are not currently being met.
To call up Check Control messages, refer
to page84.<
1 Desired speed store and increase
Press the lever forward:
The system applies and stores your current
speed as a desired speed. The speedome-
ter indicates this speed.
Subsequently pressing forward increases
the desired speed to the next 5-mile place/
10 km/h.
Each time the lever is pressed forward
again, the desired speed is increased by
another 5 mph/10 km/h until a maximum of
110 mph/180 km/h is reached. The speed
then displayed is stored and reached on a
clear road.
2 Desired speed store and decrease
Pull back the lever:
The current driving speed is rounded off to
the next 5-mile place/10 km/h, displayed
and stored.
Each time the lever is pulled back again,
the desired speed is decreased by another
5 mph/10 km/h until the minimum speed of
20 mph/30 km/h is reached. The speed
then displayed is stored and reached on a
clear road.
3 Deactivate system
Press the lever up or down while the sys-
tem is active. The displays in the speedom-
eter disappear. You can use the system
again as required.
In addition, the system is deactivated auto-
matically:
>When you apply pressure to the brake
pedal
>When you select the automatic trans-
mission's neutral range N
>When you deactivate the DSC Dynamic
Stability Control
>When you actuate the parking brake
during driving
>When the system reduces the speed to
below 20 mph/30 km/h due to a traffic
situation.
The system deactivates automatically
when the speed is set to below
20 mph/30 km/h. A gong sounds and a
message appears in the Check Control.
The active intervention of the driver is
required, otherwise there is an accident
danger.<
Background lighting
You can switch off the background lighting
of the speedometer and tachometer
>when you have deactivated the system

in city driving; heavy traffic such as during
rush hour; on curvy, winding roads, slip-
pery roads or roads with sharp curves such
as highway off-ramps; during inclement
weather such as snow, strong rain or fog;
or when entering interchanges, service/
parking areas or toll booths. It is also
important to regulate your vehicle's speed
and distance setting within applicable legal
limits. Always be ready to take action or
apply the brakes if necessary, especially
when the system is actively following a
vehicle in front of you.<
Always remember that the range and
ability of the system does have physi-
cal limitations. It will not apply the brakes or
decelerate your vehicle when there is a
slow-moving vehicle, stopped vehicle or
stationary object ahead of you, as for
example, at a traffic light or a parked vehi-
cle. Also, the system does not react to
oncoming traffic, pedestrians or other type
of potential traffic such as a rider on horse-
back. It is also possible that the system
may not detect smaller moving objects
such as motorcycles or bicycles. Be espe-
cially alert when encountering any of these
situations as the system will neither auto-
matically 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 alert-
ness.<
If while 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 vehicle will
accelerate to the speed you have selected.
Be aware that changing to a clear, unob-
st r uc ted lan e w il l als o r esu lt in y ou r v eh icle
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 man-
ner 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 vehi-
cle 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 system 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
deactivated whenever the driver applies
the vehicle brakes, shifts the transmission
from drive/D to neutral/N, or deactivates
DSC. After any deactivation, the system will
no longer automatically activate the vehicle
brakes, which means the driver must inter-
vene and resume manual braking. You
should then reactivate the system only
when you are fully aware of the prior speed
and distance settings.<
Active cruise control may brake when you
reduce the stored desired speed; however,
the driver must constantly monitor traffic
and intervene 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
canceled.
Behavior in curves
Because of the limited range of the system,
it is possible that in curves or on the peaks
and valleys of hilly roads, a vehicle ahead
may be recognized late, or not at all. There-
fore, it is up to the driver to select a speed
that is prudent in view of the curves and
terrain of the roadway.

PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Signal tones indicate the current distance
to an object behind or in front of your vehi-
cle. Four ultrasonic sensors in both the
bumpers monitor the distance to the near-
est object. The sensors at the front and at
the two rear corners have a range of
approx. 2 ft/60 cm; the rear middle sensors
have approx. 5 ft/1.50 m.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching an object at high speed,
as otherwise the physical circumstances
would mean that the system warning was
too late.<
Automatic function
Whenever the ignition is on the system
automatically assumes operational status
after a few seconds each time you engage
the transmission position R.
Wait this short period before revers-
ing.<
Switching on manually
Press the button, the indicator lamp lights
up.
Manual deactivation
Press the button again; the indicator lamp
goes out.
Automatic deactivation
The system is automatically deactivated
once the vehicle travels approx. 165 ft/
50 m or exceeds a speed of roughly
20 mph/30 km/h; the indicator lamp goes
out. You can reactivate the system manu-
ally as needed.
Signal tones
The signal indicating the distance to the
nearest obstacle is directional. Thus, an
object detected to the left rear of the vehi-
cle will be indicated by a signal tone from
the left rear speaker, etc. As the distance
between vehicle and object decreases, the
intervals between the tones become
shorter. The signal tone becomes continu-
ous once the distance to the nearest object
falls to below roughly 1 ft/30 cm.
The warning signal is canceled after
approx. 3 seconds if you are moving paral-
lel to a wall.
Malfunction
The indicator lamp within the button flashes
and a status message appears in the Check
Control. PDC has failed. Switch off PDC.
Have the system checked.
To prevent this problem, keep the sensors
clean and free of ice or snow in order to
ensure that they will continue to operate
effectively.

PDC with visual warning
You also enjoy the option of having the sys-
tem show distances to objects on the Con-
trol Display. The Control Display will also
indicate the presence of objects in green
before they are close enough to generate a
signal tone.
Select "PDC pic." from the "Settings" menu
and confirm your selection. This activates
the PDC display.
The display then appears on the Control
Display whenever the PDC is automatically
or manually activated.
The previous display automatically reap-
pears after the system is deactivated.
confirm to return to the previous dis-
play.
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 involved, there is a blind spot in which
objects cannot be detected. The system is
also subject to the physical limits that apply
to all forms of ultrasonic measurement,
such as those encountered with tow bars
and trailer couplings, as well as thin and wedge-shaped objects, etc. Low objects
already displayed, e.g. a curb, can also dis-
appear from the detection area of the sen-
sors again before a continuous tone
sounds.
Loud noises from outside and inside the
vehicle may prevent you from hearing the
PDC's signal tone.<
Keep the sensors clean and free of ice
or snow in order to ensure that they
will continue to operate effectively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Keep the spray at least 4 in/10 cm away
from the sensors.<
Driving stability control
systems
Your BMW is equipped with an extended
array of systems designed to enhance and
maintain vehicle stability under extreme
conditions. The following section describes
these functions based on DSC and ABS.
ABS Antilock Brake System
ABS enhances active safety by preventing
the wheels from locking under braking.
ABS incorporates CBC and EBV.
Malfunction
The warning lamp lights up yellow
and ABS is switched off. Conven-
tional braking efficiency remains
available without limitations. Have the sys-
tem checked as soon as possible.
CBC Cornering Brake Control
CBC is a supplement to ABS. It provides
further enhancements in vehicle stability
and steering response during lane changes
and cornering at high rates of lateral accel-
eration.
