The full-colour BMW Head-Up Display projects relevant driving information directly into the driver’s line of vision (not fully visible with polarised sunglasses), allowing him or her to fully concentrate on driving. Depending on the vehicle’s equipment, the display can also show information from the navigation system, ECO PRO tips, Check Control messages as well as information and warnings from the driver assistance systems. Frequently used functions such as telephone and entertainment services can also be displayed and operated.

The icons projected onto the windscreen are displayed in a particularly high resolution and full colour, with traffic symbols realistically reproduced. The image's projection appears as if it were 2.3 m in front of the vehicle. This in combination with optimal positioning allow the information to be read quickly, conveniently and with minimal distraction.
The brightness of the projection automatically adjusts to suit the external light conditions, while the height of the projection changes depending on whether it is day or night. The driver can also select which information to display in addition to current speed and the warnings from the driver assistance systems.

The Driving Assistant package combines the camera-based systems Lane Departure Warning and Approach and Pedestrian Warning with City Brake Activation.
The Lane Departure Warning detects lane markings and alerts the driver to an unintentional lane change at speeds above approx. 70 km/h by means of vibrations in the steering wheel. The warning is not activated if the lane change is deliberate, that is, when the turn indicator has been activated.
Whereas the Approach Warning with City Brake Activation detects vehicles, the Pedestrian Warning with City Brake Activation reacts to pedestrians. If a vehicle ahead brakes heavily, the BMW responds immediately when the Approach Warning is activated. The system operates in steps. A warning symbol is first displayed, then the symbol begins blinking and an acoustic warning is emitted, and finally the brakes are lightly applied (when travelling at speeds under 60 km/h). The Pedestrian Warning operates at speeds between 10 and 60 km/h and emits a single-level warning in the event of acute danger. If the system warns of a potential collision, the brakes are simultaneously preconditioned for a faster response. In the event of an emergency, the system applies the brakes. This function can be limited by darkness and fog.


The Navigation system Professional features a sleek design and a superior range of services. This simple, easy-to-use and seamlessly integrated navigation system is operated via the iDrive system and features the iDrive Touch Controller. It also includes the hands-free kit with USB interface and voice control, Radio Professional with a DVD drive, as well as 20 GB memory for audio files. The built-in 8.8" LCD colour display with split screen function (main and supplementary screen) is designed for optimal readability and a clear overview.
The system can be operated intuitively using the iDrive Touch Controller, which enables the user to enter their destination by writing the address on its touch-sensitive surface. The navigation system can also be operated via the direct menu control buttons, eight functional bookmarks, or voice control system. Thanks to the three-dimensional map display that makes use of satellite images as a map background – with photo-realistic depictions of selected sights – navigation becomes an exciting visual experience. Depending on the equipment fitted, the user will also have access to ConnectedDrive Services, Remote Services, Concierge Services, the internet and Real Time Traffic Information.

BMW ConnectedDrive Passenger Protection.

Active Protection is the BMW ConnectedDrive preventive passenger protection system.
After the front safety belts are buckled, they are automatically pretensioned when the car starts moving. If a critical situation arises on the road, the front seat belts are reversibly pretensioned, if required and the front side windows are closed. If there are comfort seats, the front passenger seat backrest is brought to an upright position. One example of a critical situation is emergency braking.
When the vehicle is fitted with Approach Warning or Approach Warning with Brake Activation, potential collisions with moving or stationary vehicles ahead can be recognised in advance (within the system’s limits). In certain accident situations, the system can bring the vehicle to a standstill without any intervention from the driver. This helps to reduce the likelihood of a follow-up collision and to minimise the damage caused by one.
In addition, the Attentiveness Assistant monitors the driver’s behaviour for signs of fatigue. 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.


Park Distance Control, Surround View, Rear View camera: ideal for keeping the range close to the car in sight when manoeuvring. Park Distance Control (PDC) at front and rear makes parking a convenient and safe process thanks to its visual and acoustic warnings.
Surround View shows your vehicle as seen from above in the Control Display. The Side View System included with this feature gives you a clearer view at difficult exits. The Rear View camera also provides guidance when reversing into parking spaces and at speeds of less than 20 km/h.



Increased comfort and active safety.

The Active Cruise Control with Stop&Go function including the radar-based Approach Warning and braking function, increases safety and is particularly convenient when driving in heavy 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, the BMW responds immediately when the Approach Warning is activated. Stage one consists of a visual signal, while stage two – which is triggered if the driver has not yet reacted – attracts the driver's attention by means of an acoustic signal. If the driver has still not responded, the system automatically brakes up to a maximum possible amount of deceleration.



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