System limits

Detection range

The detection capability of the system and the automatic braking performance are limited.
Two-wheeled vehicles for instance might not be detected.
Deceleration
The system does not decelerate in the following situations:
- For pedestrians or similarly slow-moving road users.
- Depending on the equipment, with red traffic lights.
- For cross traffic.
- For oncoming traffic.
Merging vehicles

If a vehicle driving ahead of you suddenly merges into your lane, the system may not be able to automatically restore the selected distance. It may not be possible to restore the selected distance in certain situations, including if you are driving significantly faster than vehicles driving ahead of you, for instance when rapidly approaching a truck. When a vehicle driving ahead of you is reliably detected, the system requests that the driver intervene by braking and carrying out evasive maneuvers, if needed.
Cornering

When the set speed is too high for a curve, the speed is reduced slightly. Because curves may not be anticipated in advance, drive into a curve at an appropriate speed.
The system has a limited detection range. Situations can arise in tight curves where a vehicle driving ahead will not be detected or will be detected very late.

When you approach a curve the system may briefly report vehicles in the next lane due to the bend of the curve. If the system decelerates you may compensate it by briefly accelerating. After releasing the accelerator pedal the system is reactivated and controls speed independently.
Driving off
In some situations, the vehicle cannot drive off automatically; for example:
- On steep uphill grades.
- In front of bumps in the road.
- With a heavy trailer.
In these cases, step on the accelerator pedal.
Weather
The following restrictions can occur under unfavorable weather or light conditions:
- Poorer vehicle detection.
- Short-term interruptions for vehicles that are already recognized.
Drive attentively, and react to the current traffic situation. If necessary, intervene actively, for instance by braking, steering or evading.
Drive power
The set speed is also maintained downhill. The speed may not be maintained on uphill grades if the drive power is insufficient.
In ECO PRO driving mode, the vehicle may exceed or drop below the set desired speed in some situations, for instance on downhill or uphill grades.

Steering Assistant
Principle
The Steering Assistant helps keep the vehicle in
the lane. For this purpose, the system executes
supporting steering movements, for instance
when driving in a curve.

Performing Vertical Acceleration Sensor Adjustment (Vertical
Dynamics Management)
NOTE: Vertical acceleration sensor adjustment must be performed after
replacement of
the spring strut/shock absorber with damper satellites.
Connect vehicle to BMW diagnosis system.
