BMW ConnectedDrive Drive Assist systems in the BMW M4 Convertible.

A suite of innovative technologies provide in-car support and guarantee the highest level of comfort and safety. So you can focus on pure driving pleasure.

Driving Assistant.

Driving Assistant combines the car’s camera-based systems - Lane Departure Warning, Forward Collision Warning, City Collision Mitigation and Preventive Pedestrian Protection.
The Lane Departure Warning detects the road’s lane markings and alerts the driver to an unintentional lane change at speeds above approx. 45 mph with a vibration in the steering wheel and a visual warning in the instrument cluster. The warning is not activated when the lane change is deliberate, i.e. when the indicator is turned on.
While the Forward Collision Warning detects vehicles, the Preventive Pedestrian Protection reacts to pedestrians. When there is a risk of collision, the Forward Collision Warning triggers a two-stage warning – a symbol in the instrument cluster lights up, followed by an acoustic alarm. The Preventive Pedestrian Protection triggers a single-stage warning in the event of an acute risk of collision. If the system warns of a potential collision, the brakes are simultaneously preconditioned for a faster response. In the event of an emergency, the City Collision Mitigation applies the brakes automatically.


Always keep an eye on the essentials: the full-colour BMW Head-up Display with M-specific function projects all information relevant for the journey directly into the driver's field of vision. With the press of a button, the driver can switch to the sportier M-specific display. Along with a digital speedometer, it also shows the selected gear and a multicoloured rev counter with shift lights for determining the best time to change gear. In addition, it can be used to display and operate navigation tips, Speed Limit Info including no-overtaking indicator, frequently used functions such as telephone and entertainment services (radio programmes, music titles), and information and warning alerts provided by Drive Assist systems. Projections at eye-level mean that the driver can keep his or her gaze on the road, improving safety and creating a unique driving experience as a result.

Speed Limit Display.

Speed Limit Display including no-overtaking indicator shows the current speed limit in the instrument cluster, as well as information regarding no-overtaking zones. This is shown on the Info Display in the instrument cluster or in the BMW Head-up Display. A camera integrated in the rear-view mirror detects relevant traffic signs. A control unit then processes and displays this information together with data from the navigation system. Features including the rain sensor are also incorporated, so variable speed limits in specific instances are also registered – under wet conditions or at certain times of day, for example – ensuring the driver is always well informed about the road ahead. 

iDrive Touch Controller.

The iDrive Touch Controller (part of Professional Navigation System) enables the Control Display to be conveniently operated with a single hand. Thanks to the touchpad integrated into the Controller, it is easy to enter information such as destinations for the navigation system.
It can be used to access and configure a wide range of functions as well as for scrolling through lists. Operation is effortless and intuitive based on the sense of touch. This makes life especially easy for the driver since it keeps distraction from traffic to an absolute minimum. All functions operated using the Controller can be viewed clearly in the Control Display.

Anti-dazzle High-Beam Assist.

With the anti-dazzle High-Beam Assist, driving at night is safer and more comfortable. It provides excellent visibility in the dark without dazzling other drivers. The system detects others on the road and selectively excludes them from the high-beam headlight distribution. Beam ranges of 400m ensure early detection of risks and improved directional tracking.

Park Assist.

Park Assist makes parallel parking easier. When the system is activated and the car is driving slowly (below 20mph), it will measure any parking gaps the car passes. When a large enough gap has been found, the driver can simply switch on the turn indicator and Park Assist will do the steering. All the driver needs to do is operate the accelerator, gears and brakes. The system also emits acoustic signals and gives instructions in the Control Display, making parking safer and simpler.

Camera Systems.

Park Distance Control, Surround View, Reversing Assistant Camera: enjoy a clear view in the area around your vehicle when manoeuvring into parking spaces and at road exits.
The Park Distance Control (PDC) at the front and rear makes parking and manoeuvring in tight spaces easier. The proximity of obstacles is indicated acoustically, as well as visually in the Control Display.
Surround View includes the Top View, Rear View and Panorama Side View camera systems. Cameras in the exterior mirrors and a Reversing Assistant camera provide a 270° view around the vehicle. The Panorama Side View makes approaching intersections and exiting driveways safer, as well as showing the traffic in front of the car on the Control Display.

Dynamic Safety.

Dyanmic Safety is the BMW ConnectedDrive preventive occupant protection system. If a critical situation arises on the road, the front seat belts are reversibly pretensioned and the side windows are closed. With Comfort seats, the front passenger seat backrest is automatically returned to an upright position. A critical situation could include emergency braking, or if the car demonstrates excessive understeer or oversteer.
After certain kinds of accidents, the system is able to automatically apply the brakes and bring the car to a standstill. This helps reduce the likelihood of a second collision or even prevent one altogether.
In addition, the Attentiveness Assist monitors the driver's behaviour for signs of inattentiveness. This system analyses the steering response and reacts to irregular driving behaviour by issuing a message in the Control Display suggesting the driver take a break.
