The system allows you to memorize and automatically maintain the required speed at a level not lower than 30 km/h.
The system can be switched on already after turning the ignition key to position 1 by pressing the button shown by the arrow. At the same time, the control lamp on the instrument panel lights up.
Pressing the key again will turn off the system.
1. Button for moving at a given speed, memorization and acceleration
Press the button.
The actual speed is entered into the system memory and kept constant. Each subsequent press of the button will increase the speed by 1 km/h.
If you keep the button pressed, the car will accelerate without affecting the accelerator pedal. If you release the button, the speed reached up to this point will remain in the system memory and will be maintained constant.
2. Slow down button
Press the button.
If before that the movement has already occurred in the mode of maintaining the set speed, then each time you press the button, the speed will decrease by 1 km / h. If you keep the button pressed, then when driving at the set speed mode, the throttle opening degree will automatically decrease and the car will slow down. If you release the button, then the speed reached by this moment will remain in the system memory and will be maintained constantly.
3. Call button
Press the button.
The last of the entered speed values will be called, to which it will first be brought, and then it will be maintained constant.
4. Automation off button
Press the button.
Automatic maintenance of the set speed will immediately turn off.
In addition, the system will automatically turn off in the following cases:
- When braking, disengaging the clutch or when moving the AT control lever from position D to position N
For BMW 520i, 523i, 528i, 535i, 540i: if the set speed is exceeded for more than 30 seconds and more than 16 km/h
For BMW 525tds: if the set speed is exceeded by more than 16 km/h or reduced by more than 20 km/h. By turning the ignition key to position 0, the system will turn off and the speed entered will be erased.
It is impossible to use the automatic maintenance of a given speed if the track is replete with turns or if the increased traffic density does not allow moving evenly, as well as on slippery (due to snow, rain, ice) road or weak (gravel, wood) ground. Otherwise, your driving style will not match the traffic situation.
