Deactivate system
Press the lever up or down while the system is
active3. The displays in the instrument cluster
disappear. You can use the system again as
required.
In addition, the system is deactivated automati-
cally:
>When you apply pressure to the brake pedal
>When you select the automatic transmis-
sion's/SMG neutral position N
>When the manual transmission is in neutral
>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 situ-
ation
The system deactivates automatically
when the speed is set to below 20 mph/
30 km/h. An acoustic signal sounds and a mes-
sage appears on the Control Display. The active
intervention of the driver is required.<
When you switch off the ignition, the stored
desired speed is deleted.
Resume to stored desired speed and
distance setting
Press button4 when the system is deactivated.
The displays appear in the instrument cluster.
The system is reactivated and uses the last
stored desired speed and distance setting.
Fine adjustment of desired speed
In the activated state, the desired speed
increases by 1 mph/1 km/h each time button4
is pressed briefly.
Select distance
You can choose from four distance steps.
>Rotary switch downward:
Increase distance.
>Rotary switch upward:
Decrease distance.
The selected distance is displayed in the instru-
ment cluster.
Distance 1
Distance 2
Distance 3
This distance is always set when
the system is used for the first time
after starting the engine.
Distance 4
Use good judgment to select the appro-
priate following distance given road con-
ditions, traffic, applicable laws and driving rec-
ommendations for safe following distance.<

Active cruise control may brake when you
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.
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.
In approaching a curve, it is possible that active
cruise control would react briefly to a vehicle in
the adjacent lane. In addition, the system can
sense if your vehicle is in a curve and may not
accelerate. If your vehicle decelerates in either
case, you can choose to overcome the deceler-
ation by briefly pressing the accelerator pedal.
Driver interventions
Anytime the driver presses down on the
accelerator pedal, any automatic braking
action by the system is interrupted until the
pedal is fully released. After doing this, release
the accelerator and the system again controls
your cruising speed and distance setting. While
driving with activated system, resting your foot
on the accelerator pedal will cause the system
not to brake even if necessary. Be certain that
floormats or other objects on the vehicle floor
do not interfere with movement of the accelera-
tor pedal.<
While active cruise control is capable of
braking your vehicle automatically when
you approach a slower vehicle ahead, it is
important to be aware that the ability of the sys-
tem to apply the brakes is also limited, if you are
driving down a steep grade or when you reduce
your desired speed sharply. The system cannot
stop your vehicle. It uses only a portion of brak-
ing system capacity and does not utilize the full
capacity of the vehicle braking system. There-
fore, the system cannot decrease your speed
for large differences in speed between your
vehicle and the vehicle ahead. Examples: during
emergency braking, when you approach a vehi-
cle traveling at a much lower speed than your
own speed such as when approaching a toll
booth or when a much slower vehicle cuts in
front of you at close range.<
Whenever active cruise control
recognizes a situation that requires
driver braking because the system
capacity has been reached or has
been exceeded, the system alerts
the driver by flashing this symbol in the instru-
ment cluster and sounding a signal.

Check Control
The concept
The Check Control monitors functions in the
vehicle and issues a message if there is a mal-
function in the monitored systems.
Supplementary messages on the Control Dis-
play are intended to assist you in assessing the
severity of malfunctions; they provide you with
the information you need to decide on the best
way to respond.

Requesting information
As of ignition key position 1, you can use the BC
button in the turn signal lever to call up com-
puter information in the instrument cluster.
A new function appears each time you press the
BC button.
In instrument cluster
The display sequence:
>Cruising range
>Average speed
>Average fuel consumption
Cruising range
Displays the estimated cruising range available
with the remaining fuel. It is projected by taking
into account the driving style over the last
20 miles/30 km.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km, as otherwise engine functions are not
ensured and damage can occur.<
Average speed
Periods with the vehicle parked and the engine
off are not included in the calculations of aver-
age speed.
To reset the average speed: press the BC but-
ton in the turn signal lever for approx. 2 sec-
onds.
Average fuel consumption
The average fuel consumption is calculated for
the time during which the engine is running.
You can use the Control Display to view your
fuel consumption rate over two different dis-
tances, refer to page75.
To reset the average fuel consumption: press
the BC button in the turn signal lever for approx.
2seconds.
On Control Display
You can also call up the computer via the Con-
trol Center, for principle details, refer to
page16.

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 ultra-
sonic measurement, such as those encoun-
tered with thin and wedge-shaped objects, etc.
Low objects already displayed, e.g. a curb, can
also disappear from the detection area of the sensors again before a continuous tone
sounds.
Loud noises from outside and inside your vehi-
cle may prevent you from hearing the PDC sig-
nal tone.<
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.
ABS Antilock Brake System
ABS prevents the wheels from locking during
braking. Safe steering response is maintained
even during hard braking. This increases active
driving safety.
ABS is operational every time you start the
engine. For information on safe braking, refer to
page109.
CBC Cornering Brake Control
This system provides further enhancements to
vehicle stability and steering response when
braking while cornering or when braking during
a lane change.
Electronic brake-force distribution
This system controls the brake system's appli-
cation pressure at the rear wheels to ensure
stable deceleration.
DBC Dynamic Brake Control
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during panic
stops. This system exploits all of the benefits
provided by ABS.
