Stability system Roll StabilityControl
The Roll Stability Control (RSC 1
) system helps
minimize the risk of a rollover in the event of e.g. a sudden evasive maneuver or if the vehiclebegins to skid.
The RSC system monitors the lateral angle at which the vehicle is leaning and registers anychanges. Using this information, the system cal-culates the likelihood of a rollover. If there is animminent risk of a rollover, Electronic StabilityControl is activated, engine torque is reduced andbrakes are applied to one or more of the wheelsuntil the vehicle has regained stability.

Changing Automatic Speed Limitertolerance The Automatic Speed Limiter (ASL 20
) can be set
to different tolerance levels.
It is also possible to allow the vehicle to drive above or below the posted speed limit. For exam-ple, if the vehicle is following a current postedspeed limit of 70 km/h (43 mph), the driver caninstead allow the vehicle to maintain a speed of75 km/h (47 mph).

.
–Tap the (1) button on the steering
wheel keypad until 70 km/h (43 mph) has been changed to 75 km/h (47 mph) in thecenter of the speedometer (4).
> The vehicle will then use the selected tol- erance of 5 km/h (4 mph) as long as the posted speed limit the vehicle passes is70 km/h (43 mph). This tolerance level will be followed until the vehicle passes a sign with a lower orhigher speed. The vehicle will then adjustto the new speed limit and the set toler-ance will be deleted from the system'smemory. If Road Sign Information * is activated, the
posted speed limit will then be indicated by a RED marking on the speedometer'sspeed scale.
The set tolerance can be adjusted in the sameway as for the Speed Limiter's speed.

Automatic Speed Limiter limitations
ASL utilizes the speed limit information provided by the RSI 22
system, not from the speed limit
signs that the vehicle passes.
If RSI 22
is unable to interpret and provide ASL
with speed information, ASL will go into standby mode and switch over to SL. The driver will thenhave to actively brake to bring the vehicle downto the appropriate speed. ASL will be reactivated when RSI 22
is once again
able to interpret and provide speed information to ASL. See "Road Sign Information limitations" for more information.
