Changing the tolerance for the Automatic speed limiter
The speed limiter function (Automatic Speed Limiter - ASL) can be set for different tolerancelevels.
It is possible to increase/decrease the signed speed limit. If, for example, the car follows asigned speed limit of 70 km/h (43 mph) thedriver can instead choose to allow the car tomaintain 75 km/h (47 mph).
Buttons and symbols for functions.
–Press the steering wheel button (1)
until 70 km/h (43 mph) in the centre of the speedometer (4) changes to 75 km/h(47 mph).
> After which, the car uses the selected tol- erance 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 signedspeed limit instead and the tolerance isdeleted from the memory. If the Road Sign Information * function is
activated, the signed speed limit will then be shown with a RED indicator on thespeedometer. The tolerance is adjusted in the same way as thespeed setting is in the speed limiter.
NOTE
The maximum selectable tolerance is +/- 10 km/h (5 mph).
