BMW 7 Series: Active Cruise Control with Stop & Go function ACC- Displays in the Head-up Display

Desired speed

Some system information can also be displayed in the Head-up Display.

The symbol is displayed when the
set desired speed is reached.

Distance information

The symbol is displayed when the
distance from the vehicle traveling ahead is too short.

The distance information is active in the following situations:

  • Active Cruise Control switched off.
  • Display in the Head-up Display selected.

    Head-Up Display

  • Distance too short.
  • Speed greater than approx. 40 mph/70 km/h.

System limits

Detection range

Detection range


The detection capacity of the system and the automatic braking capacity 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.
  • For red traffic lights.
  • For cross traffic.
  • For oncoming traffic.

Swerving vehicles

Swerving vehicles


A vehicle driving in front of you is not detected until it is completely within the same lane as your vehicle.

If a vehicle driving ahead of you suddenly swerves 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

Cornering


When the desired 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.

Cornering


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.

In these cases, step on the accelerator pedal.

Weather

The following restrictions can occur under unfavorable weather or light conditions:

  • Poorer vehicle recognition.
  • Short-term interruptions for vehicles that are already recognized.

Examples of unfavorable weather or light conditions:

  • Wet conditions.
  • Snowfall.
  • Slush.
  • Fog.
  • Glare.

Drive attentively, and react to the current traffic situation. If necessary, intervene actively, for instance by braking, steering or evading.

Engine power

The desired speed is also maintained downhill.

The speed may not be maintained on uphill grades if the engine 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.

Malfunction

Radar sensor

The system cannot be activated if the radar sensor is not aligned correctly. This may be caused by damage incurred, for instance during parking.

A Check Control message is displayed if the system fails.

Have the system checked by a dealer's service center or another qualified service center or repair shop.

The system may be impaired when the detection range of the radar sensor is partially covered such as by the license plate holder.

Camera

The function for detecting and responding when approaching stationary vehicles may be limited in the following situations:

  • During calibration of the camera immediately after vehicle delivery.
  • If the camera is malfunctioning or dirty. A Check Control message is displayed.
