Active Protection The concept The Active Protection safety package consists of systems that are independent of each other: ▷ PreCrash ▷ PostCrash PreCrash The concept The system is used to detect critical driving sit‐ uations that might lead to an accident. In in these situations, preventative protection measures are automatically undertaken to minimize the risk in the event of an accident as much as pos‐ sible. Critical driving situations may include: ▷ Full application of the brakes. ▷ Severe understeering. ▷ Severe oversteering. If the vehicle includes the collision warning fea‐ ture, impending collisions with vehicles driving

Personal responsibility The system cannot serve as a substitute for the driver's personal judgment of the traffic situation. The system may not always detect critical situations reliably and in a timely manner. Adapt speed to traffic situation and drive alertly; otherwise, a risk to safety may result.◀
Function After the safety belt is buckled, the front belts are automatically tightened once after the vehi‐ cle is driven is away. In critical driving situations, the following indi‐ vidual functions become active: ▷ The front belts are automatically tightened. ▷ Automatic closing of the windows. ▷ Automatic closing of the glass sunroof. After a critical driving situation without an acci‐ dent, the front belts are loosened again. All other systems can be restored to the desired setting. If the belt tension does not loosen automatically, stop the vehicle and unbuckle the belt using the red button in the buckle. Fasten the belt before continuing on your trip. PostCrash In the event of an accident, the system can bring the car to a halt automatically without interven‐ tion by the driver in certain situations. This can reduce the risk of a further collision. Depressing the brake pedal can cause the vehi‐ cle to brake harder. This interrupts automatic braking. Depressing the accelerator pedal also interrupts automatic braking. After coming to a halt, the brake is released au‐ tomatically. Secure the vehicle against rolling.

Driving stability control systems Vehicle equipment All standard, country-specific and optional equipment that is offered in the model series is described in this chapter. Therefore, equipment is also described that is not available in a vehicle, e. g., because of the selected optional equip‐ ment or country variant. This also applies for safety-related functions and systems.
to physical limits, DSC helps to keep the vehicle on a steady course by reducing engine speed and by applying brakes at individual wheels. Adjust your driving style to the situation An appropriate driving style is always the
responsibility of the driver. The laws of physics cannot be repealed, even with DSC. Therefore, do not reduce the additional safety margin by driving in a risky manner.◀
Antilock Brake System ABS ABS prevents locking of the wheels during brak‐ ing. The vehicle remains steerable even during full brake applications, thus increasing active safety. ABS is operational every time you start the en‐ gine.
Brake assistant When you apply the brakes rapidly, this system automatically produces the maximum braking force boost. It thus helps to achieve the shortest possible braking distance during full braking. This system utilizes all of the benefits provided by ABS. Do not reduce the pressure on the brake pedal for the duration of the full braking.
DSC Dynamic Stability Control The concept DSC prevents traction loss in the driving wheels when driving away and accelerating. DSC also recognizes unstable vehicle condi‐ tions, such as fishtailing or nose-diving. Subject

DTC Dynamic Traction Control The concept The DTC system is a version of the DSC in which forward momentum is optimized. The system ensures maximum forward momen‐ tum on special road conditions, e.g., unplowed snowy roads, but driving stability is limited. It is therefore necessary to drive with appropri‐ ate caution. You may find it useful to briefly activate DTC un‐ der the following special circumstances: ▷ When driving in slush or on uncleared,
snow-covered roads.
▷ When rocking the vehicle or driving off in
deep snow or on loose surfaces. ▷ When driving with snow chains. Deactivating/activating DTC Dynamic Traction Control Activating the Dynamic Traction Control DTC provides maximum traction on loose ground. Driving stability is limited during acceleration and when driving in bends. Activating DTC
Press the button. TRACTION is displayed in the instru‐
ment cluster and the indicator lamp for DSC OFF lights up.
Dynamic Damping Control The concept This system reduces undesirable vehicle mo‐ tion when using a dynamic driving style or trav‐ eling on uneven road surfaces. The system enhances driving dynamics and comfort as required for the road surface and driving style. Programs The system offers two different programs. The programs can be selected via Dynamic Driv‐ ing Control, refer to page 106. SPORT Consistently sporty control of the shock absorb‐ ers for greater driving agility. SPORT+ Consistently sporty control of the shock absorb‐ ers for greater driving agility when driving with limited driving stabilization. COMFORT Balanced control of the vehicle.
Variable sport steering The variable sport steering increases the steer‐ ing angle of the front wheels at large steering wheel angles, e.g., in tight curves or when park‐ ing. Steering becomes more direct. It also varies the force required to turn the wheels in accordance with the vehicle speed.

Therefore, equipment is also described that is not available in a vehicle, e. g., because of the selected optional equip‐ ment or country variant. This also applies for safety-related functions and systems.
Active Cruise Control with Stop & Go function, ACC The concept This system can be used to select a desired speed that the vehicle will maintain automati‐ cally on clear roads. To the extent possible, the system automatically adjusts the speed to a slower vehicle ahead of you. The distance that the vehicle maintains to the vehicle ahead of you can be varied. For safety reasons, it depends on the speed. To maintain a certain distance, the system au‐ tomatically decelerates, applies the brakes lightly, or accelerates again if the vehicle ahead begins moving faster. If the vehicle ahead of you brakes to a halt, the system is able to detect this within the given system limits. If the vehicle ahead of your drives away again from a halt, your vehicle is able to accelerate if operated accordingly. Even if some time passes before the vehicle drives away again, the BMW can still be accel‐ erated automatically and simply. As soon as the road is clear, it accelerates to the desired speed. The speed is also maintained on downhill gra‐ dients, but may not be maintained on uphill slopes if engine power is insufficient.

Radar sensor Position
If the desired speed is too high for a curve, the speed is reduced slightly in the curve, although curves cannot be anticipated in advance. There‐ fore, drive into a curve at an appropriate speed. In tight curves, situations may result due to the restricted detection range of the system in which a vehicle driving ahead of you may not be detected at all, or not until after a considerable delay.
When approaching a curve, the system may re‐ act briefly to the vehicles in the next lane due to the bend of the curve. Any deceleration of the vehicle by the system can be compensated for by briefly accelerating. After the accelerator pedal is released, the system becomes active again and independently controls the speed.

Unfavorable conditions Do not use the system if unfavorable con‐ ditions make it impossible to drive at a constant speed, for instance: ▷ On curvy roads. ▷ In heavy traffic. ▷ On slippery roads, in fog, snow or rain, or on
a loose road surface.
Otherwise, you could lose control of the vehicle and cause an accident.◀

Avoid driving away quickly while PDC is not yet active. For technical reasons, the system may other‐ wise be too late in issuing a warning.◀
PDC Park Distance Control The concept In addition to the PDC Park Distance Control, the backup camera, refer to page 123, can be switched on. PDC supports you when parking. Objects that you are approaching slowly in front of or behind your vehicle are indicated with: ▷ Signal tones. ▷ Visual display. Measurement Measurements are made by ultrasound sensors in the bumpers. The range is approx. 6 ft/2 m. An acoustic warning is first given: ▷ By the front sensors and two rear corner
sensors at approx. 24 in/60 cm.
▷ By the rear middle sensors at approx. 5 ft/
1.50 m.
System limits
Check the traffic situation as well PDC cannot serve as a substitute for the driver's personal judgment of the traffic situa‐ tion. Check the traffic situation around the vehi‐ cle with your own eyes. Otherwise, an accident could result from road users or objects located outside of the PDC detection range. Loud noises from outside and inside the vehicle may prevent you from hearing the PDC's signal tone.◀
Avoid driving quickly with PDC Avoid approaching an object quickly.
Limits of ultrasonic measurement The detection of objects can reach the physical limits of ultrasonic measurement, e.g.: ▷ With tow bars and trailer hitches. ▷ With thin or wedge-shaped objects. ▷ With low objects. ▷ With objects with corners and sharp edges. Low objects already displayed, e.g., curbs, can move into the blind area of the sensors before or after a continuous tone sounds. High, protruding objects such as ledges may not be detected. False warnings PDC may issue a warning under the following conditions even though there is no obstacle within the detection range: ▷ In heavy rain. ▷ When sensors are very dirty or covered in
ice.
▷ When sensors are covered in snow. ▷ On rough road surfaces. ▷ In large buildings with right angles and
smooth walls, e.g., in underground garages.
▷ In heavy exhaust. ▷ Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam cleaners or neon lights. The malfunction is signaled by a continuous tone alternating between the front and rear speakers. As soon as the malfunction due to other ultrasound sources is no longer present, the system is again fully functional.

For example, if an object is detected to the left rear of the vehicle, a signal tone sounds from the left rear speaker. The shorter the distance to the object becomes, the shorter the intervals. If the distance to a detected object is less than approx. 12 in/30 cm, a continuous tone is sounded. If objects are located both in front of and behind the vehicle, an alternating continuous signal is sounded. The intermittent tone is interrupted after approx. 3 seconds:
▷ If the vehicle stops in front of an object that is detected by only one of the corner sen‐ sors.
▷ If moving parallel to a wall. The signal tone is switched off: ▷ When the vehicle moves away from an ob‐
