The signposted speed limit can be increased or decreased by 5 km/h (5 mph) - if, for example, the car is following a signposted speed limit of 70 km/h (40 mph) but the driver wishes to travel at 75 km/h (45 mph) instead.
Press the steering wheel button 
(1) until 70 km/h (40 mph) has been changed to 75 km/h (45 mph) in the centre of the speedometer (4).
(1) until 70 km/h (40 mph) has been changed to 75 km/h (45 mph) in the centre of the speedometer (4).The car then uses the selected tolerance 5 km/h (5 mph) as long as passed signs show 70 km/h (40 mph).
The tolerance is followed until a road sign with a lower or higher speed is passed - then the car follows the new signposted speed limit instead and the tolerance is deleted from the memory.
If the Road Sign Information* function is activated, the signposted speed limit will then be shown with a RED indicator on the speedometer.
The tolerance is adjusted in the same way as the speed setting is in the Speed limiter.
