city driving; heavy traffic such as during rush hour; on curvy, winding roads, slippery roads or roads with sharp curves such as highway off- ramps; during inclement weather such as snow, strong rain or fog; or when entering inter- changes, 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. Otherwise driving situations could result that pose the risk of accidents.<

4 Selected desired speed is temporarily dis-
played
If --- mph or --- km/h temporarily appears in the instrument cluster display, it is pos- sible that the system prerequisites for operation are currently not met. Calling up Check Control messages, refer to page 76.<
Warning lamps
The indicator 2 flashes in red; a signal sounds. The system indicates that you must brake and/or maneuver the vehicle yourself. Active cruise con- trol cannot automatically restore the distance to the vehicle ahead. This indicator does not release you from your responsibility to adapt your desired speed and driving style to prevailing driving conditions.
The indicator 2 flashes in yellow. The prerequisites for operating active cruise control are not met, e.g. as a result of ABS or DSC interventions. Active cruise control is deactivated. You can reactivate the system, if desired, by tapping or pulling the lever when road and traffic conditions permit. It is not pos- sible to resume a stored speed.
Radar sensor
1 Stored desired speed 2 Shows yellow: vehicle detected ahead
Flashes in red: system cannot maintain dis- tance; driver must brake the vehicle Flashes in yellow: driving stability control systems are intervening; cruise control is deactivated
3 Selected distance to vehicle ahead
The indicator lights up as soon as the sys- tem is activated.
64
The sensor's ability to detect vehicles ahead may be restricted as a result of heavy rain, dirt, snow or ice. If necessary, clean the radar sensor located in the front bumper, see arrow. Be sure to use particular care when removing any layers of snow or ice from the sensor.
ba8_E9091_cic.book Seite 65 Mittwoch, 29. Oktober 2008 2:59 14
When the radar sensor is not properly posi- tioned, active cruise control cannot be activated at all.
Malfunction
The warning lamp comes on when the system has failed. A message appears on the Control Display. You can find more information starting on page 75.
System limitations
Always remember that the range and abil- ity of the system does have physical limi- tations. It will not apply the brakes or decelerate 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 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 motor- cycles or bicycles. Be especially alert when encountering any of these situations as the sys- tem 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 alert- ness.<
Active cruise control is not and must not be used as a collision avoidance/warning
system.< If while your vehicle is actively following a vehi- cle 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, 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.
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, e.g. when you reduce your desired speed sharply. The system cannot stop your vehicle. It uses only a portion of braking system capacity and does not utilize the full capacity of the vehicle braking system. Therefore, the system cannot decrease your speed for large differences in speed between your vehicle and the vehicle ahead. Examples: when you approach a vehicle traveling at a much lower speed than your own speed such as approaching a toll booth or when a much slower vehicle cuts in front of you at close range.< Active cruise control can only decelerate the vehicle to approx. 20 mph or 30 km/h.
65
ba8_E9091_cic.book Seite 66 Mittwoch, 29. Oktober 2008 2:59 14
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.
When a vehicle ahead suddenly swerves into your lane, the system may not be able to maintain the selected distance automatically. This also applies to great differences in speed between you and vehicles ahead, e.g. when quickly approaching a truck. There is a risk of collision. Once the system has established that a vehicle is indeed in front of you, it will indicate that you must brake and/or maneuver the vehi- cle yourself. Take action yourself, otherwise there is a risk of an accident.<
Behavior in curves
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.
Your responsibility Your actions have priority at all times. When you press the accelerator pedal while driving with active cruise control, the automatic braking function will be temporarily interrupted. Once you release the accelerator pedal, the desired speed or the selected distance to the vehicle ahead is achieved again.
Do not leave your foot on the accelerator pedal and make sure that no objects such as floor mats are lying on the accelerator pedal. Otherwise the system may not be able to brake the vehicle.<
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 driving comfort and safety
Park Distance Control PDC*
The concept The PDC assists you with maneuvering in tight parking spaces. Acoustic signals and a visual indicator warn you of the presence of an object behind your vehicle. To measure the distance, there are four ultrasonic sensors in either bumper. These sensors have a range of approx. 6.5 ft/ 2 m. However, an acoustic warning does not sound until an object is approx. 24 in/60 cm from the corner sensors, or approx. 5 ft/1.50 m from the center sensors.
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, oth- erwise physical circumstances may lead to the system warning being issued too late.<
Switching on automatically With the engine running or the ignition switched on, the system is activated after approx. 1 sec- ond when you engage reverse gear or move the automatic transmission selector lever to position R. Wait this short period before driving.
Switching off automatically After approx. 165 ft/50 m of driving or above approx. 20 mph/approx. 30 km/h, the system switches off and the LED goes out.
Signal tones When nearing an object, its position is indicated correspondingly by an interval tone. As the dis- tance between vehicle and object decreases, the intervals between the tones become shorter. If the distance to the nearest object falls to below roughly 1 ft/30 cm, then a contin- uous tone sounds. An interval tone is interrupted after approx. 3 seconds
80
> if you remain in front of an object that has been detected by only one of the corner sensors
> if you are driving parallel to a wall.
Malfunction
The indicator lamp in the instrument cluster comes on. PDC is malfunc- tioning. A message appears on the
Control Display. Have the system checked. To avoid this problem, keep the sensors clean and free of ice or snow in order to ensure that they will continue to operate effectively. When using a high-pressure cleaner, do not spray the sensors for extended periods of time and only from a distance of at least 4 in/10 cm.
PDC with visual warning The approach of the vehicle to an object is shown on the Control Display. Objects that are farther away are displayed on the Control Dis- play before a signal tone sounds. The display appears on the Control Display as soon as PDC is activated.
System limitations
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 trailer towbars and hitches, thin or wedge-shaped objects, etc. Low objects that have already been displayed, e.g. curbs, can disappear again from the detection area of the sensors before or after a continuous tone sounds. Higher, protruding objects, e.g. ledges, cannot be detected. Therefore, always drive cautiously, otherwise there is a risk of personal injury or property damage. Loud sound sources outside or inside the car
ba8_E9091_cic.book Seite 81 Mittwoch, 29. Oktober 2008 2:59 14
can drown out the PDC signal. Therefore, always drive cautiously, otherwise there is a risk of personal injury or property damage.<
style always remains the responsibility of the driver. Therefore, do not reduce the additional safety margin again by taking risks, as this could result in an accident.<
Driving stability control systems Your BMW has a number of systems that help to maintain the vehicle's stability even in adverse driving conditions.
Antilock Brake System ABS 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 page 116.
Electronic brake-force distribution The system controls the brake pressure in the rear wheels to ensure stable braking behavior.
Dynamic Brake Control DBC 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 full brak- ing. This system exploits all of the benefits pro- vided by ABS. Do not reduce the pressure on the brake for the duration of the full braking application.
Dynamic Stability Control DSC DSC prevents the driving wheels from losing traction when you pull away from rest or accel- erate. The system also recognizes unstable driving conditions, for example if the rear of the car is about to swerve or if momentum is acting at an angle past the front wheels. In these cases, DSC helps the vehicle maintain a safe course within physical limits by reducing engine output and through braking actions at the indi- vidual wheels.
The laws of physics cannot be repealed, even with DSC. An appropriate driving
Deactivating DSC
Press the button for at least 3 seconds; the indi- cator lamps for DSC in the instrument cluster light up. Dynamic Traction Control DTC and DSC have been simultaneously deactivated. Stabilizing and drive-output promoting actions are no longer executed. 328i, 335i: in the same way as with a differential interlock, even if DSC is deactivated, brake actions are still performed on the rear axle to enhance drive output if the drive wheels experi- ence a significant loss of traction. To increase vehicle stability, activate DSC again as soon as possible.
Activating DSC Press the button again; the indicator lamps in the instrument cluster go out.
For better control
If the indicator lamp flashes: DSC controls the drive forces and brake forces. If the indicator lamps are on: DSC is deactivated.
Dynamic Traction Control DTC 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
