Lane Change Warning monitoring traffic approaching from behind.

Optional Lane Change Warning in the new BMW 5 Series warns the driver

of potentially critical situations when overtaking. Using two radar sensors at

the rear end of the car, the system monitors traffic conditions on the adjacent

lanes, covering an area extending from the blind angle on the next lane

all the way back about 60 metres or almost 200 feet. A triangular yellow

light symbol integrated in the housing of the driver’s exterior mirror shows

the driver that a vehicle is in the critical range, requiring him to check out

the situation carefully.

Should the driver set the direction indicator nevertheless, indicating that he

is about to change lanes, the LED signal in the light will warn him by flashing

on and off. He will also be warned by discreet but unmistakable vibration of

the steering wheel.

Lane Departure Warning: camera-based system warning the driver

from unintended lane departure even in the dark.

Likewise available as an option, Lane Departure Warning detects unintended

departure from the appropriate lane at a speed of at least 70 km/h or 43 mph.

This system is made up of a camera fitted near the interior mirror on the

windscreen, a control unit for comparing data, and a signal generator making

the steering wheel vibrate as in the case of a Lane Change Warning.

Lane Departure Warning operates as a function of road speed. At high

speeds the system interacts quickly as soon as the car draws close to

the side of the road. It does not send out a warning signal, however, if the

driver has indicated his intention to change lanes or direction by setting

the direction indicator.

The camera incorporated in the Lane Departure Warning system monitors

the road markings on at least one side of the car, a control unit calculating the

position of the vehicle in relation to such road markings. The camera is able

to look ahead about 50 metres or 165 feet, and is also able to respond

appropriately in bends or on narrow lanes. The system even works in the dark

once the headlights have been switched on, making it very helpful under very

many everyday driving conditions.

Speed Limit Info and Speed Limit Device.

The camera fitted in the interior mirror also allows the installation of another

driver assistance system for extra comfort on the road: Combined with the

Professional navigation system, Speed Limit Info helps the driver to keep

informed on the speed limit on the route he is currently taking. To provide

this function the camera permanently monitors both the signs along the road
