Driver assistance systems in the BMW 4 Series Coupé.

Playing it safe in the BMW 4 Series Coupé. Our driver assistance systems give you innovative and clever support and set standards in terms of safety and comfort.

Head-up Display.

The full-colour BMW Head-up Display projects relevant driving information directly into your line of sight, allowing you to concentrate fully on driving. It displays information from the navigation system, notifications from the Speed Limit Display including no-overtaking indicator and Check Control messages. You can also have infotainment information displayed such as radio station, track titles, phone book entries and call lists.
The icons projected onto your windscreen are displayed in high resolution and full colour, with traffic symbols reproduced realistically. The information is displayed on the windscreen to ensure effective ergonomics and can be individually adapted. Head-up Display is not fully visible if you are wearing polarised sunglasses.
  • The illumination intensity is automatically modified to suit the external light conditions and the system also features night-time and day-time modes. The brightness setting can be configured via the iDrive menu. You can also select which additional information you wish to have displayed in addition to your current speed and the warnings from the driver assistance systems.

Camera systems.

Park Distance Control, Surround-view, Reversing Assist camera - enjoy a clear view in the area around your vehicle when manoeuvring into parking spaces and at road exits. Park Distance Control (PDC) at the front and rear as standard allows you to park safely and comfortably thanks to optical and acoustic signals.
Surround-view shows your vehicle in the Control Display with the aid of a projection from above. The Side-view system included in this equipment option guarantees a better overview when visibility is poor at road exits. The Reversing Assist camera provides welcome support when you are reversing into parking spaces at speeds of less than 12 mph.

Active Cruise Control with Stop&Go function.

The optional Active Cruise Control with Stop&Go function increases safety and is particularly convenient when driving in dense traffic. In addition, the system constantly measures the distance to vehicles in front and maintains a preselected distance.
The Stop&Go function not only automatically regulates speed down to standstill, it also automatically accelerates back up to the desired speed as soon as traffic flow allows.
If a vehicle ahead brakes heavily, your BMW responds immediately when the collision warning is activated. Stage 1 consists of a visual signal, while stage 2 - which is triggered if you have not yet reacted - attracts your attention by means of an acoustic signal.

Dynamic Safety.

Dynamic Safety is the BMW ConnectedDrive preventive occupant protection system. If a critical situation arises on the road, the front safety belts are reversibly pretensioned and the side windows closed - as is the sliding roof, if there is one. A critical situation would include an emergency stop made by the driver, or if the automobile demonstrated excessive understeer or oversteer. In certain accident situations, maximum deceleration can be applied to your automobile to bring it to a complete standstill. This helps reduce the likelihood of a second collision or even prevent one altogether. The Attentiveness Assistant also monitors your behaviour for signs of fatigue; your steering responses are analysed and the system reacts to irregular driving behaviour. Then, if necessary, a notification appears in the Control Display suggesting you take a break.

Glare-free High-beam Assistant.

Included with the Adaptive Headlights and LED Headlights, the High-beam Assistant continuously illuminates the road at night with full beam without dazzling other road users. This minimises fatigue during night driving, making it significantly safer. A camera sensor in the rear-view mirror holder registers the position of other road users and a mechanism on the inside of the headlight selectively produces blind spots for them within the headlight beam. As the driver, you benefit from the power and range of the permanently activated high beam. You can spot hazards earlier and you don’t have to worry about constantly dipping the beam for oncoming drivers.

Speed Limit Display.

The Speed Limit Display including no-overtaking indicator shows you the current speed limit as well as whether or not overtaking is allowed. This is indicated in the Info Display in the instrument cluster and in the Head-up Display. A special camera detects the relevant traffic signs. This information is processed by a control unit along with data from the navigation system. Features including the rain sensor are also incorporated, so variable speed limits in wet conditions (for example) are also registered. This means you’ll always be well informed about the road ahead.

Drive Assist.

Drive Assist feature combines the camera-based systems lane departure warning and collision warning.
It detects lane markings and warns you of an unintentional lane change at speeds from approximately 44 mph, by means of vibrations in the steering wheel and a visual warning in the instrument cluster. The warning is not activated if the lane change is deliberate, in other words if the turn indicator has been activated. The camera also detects pedestrians. Here again you are warned if there is the risk of a collision, and if necessary the brakes applied.
The system also warns you of a potential collision with a vehicle ahead from speeds of approximately 9 mph, as well as conditioning the brakes for a faster response.

iDrive Touch.

The iDrive Touch Controller gives you convenient control of the iDrive system with one hand. Thanks to the touchpad integrated in the Controller, you can easily enter such information as destinations for the navigation system. You can also use it to access a wide range of functions and settings as well as for scrolling through lists. Operation is effortless and intuitive by means of touch - a great help for you as the driver since it barely distracts your concentration on the road. All functions operated using the Controller can be conveniently viewed in the Control Display.
