If, for example, the car follows a signed speed limit of 70km/h (43 mph) the driver can instead choose to allow the car to maintain 75 km/h (47 mph).
Buttons and symbols for the function
Press the steering wheel button (1) until 70 km/h (43 mph) in the centre of the speedometer (2) changes to 75 km/h (47 mph).
After which, the car uses the selected tolerance 5 km/h (4 mph) as long as signs passed are showing 70 km/h (43 mph).
The tolerance is followed until a road sign with a lower or higher speed is passed - then the car follows the new signed speed limit instead and the tolerance is deleted from the memory.
The maximum selectable tolerance is +/- 10 km/h (5 mph).
