Stability system
The Roll Stability Control (RSC 10
) system
helps reduce the risk of a rollover in the event of e.g. a sudden evasive maneuver or if thevehicle begins to skid.
The system monitors the lateral angle at which the vehicle is leaning and registers anychanges. Using this information, the systemcalculates the likelihood of a rollover. If there isan imminent risk of a rollover, Electronic Sta-bility Control is activated, engine torque isreduced and brakes are applied to one or moreof the wheels until the vehicle has regainedstability.

active.
WARNING
Distance Alert only reacts of the time inter- val to the vehicle ahead is shorter than thepreset value – vehicle speed is not affec-ted.
WARNING
The function is supplementary driver support intended to facilitate drivingand help make it safer – it cannot han-dle all situations in all traffic, weatherand road conditions.
The driver is advised to read all sec-tions in the Owner's Manual about thisfunction to learn of its limitations,which the driver must be aware ofbefore using the function.

Distance Alert limitations 13
Distance Alert functionality may be reduced in certain situations. The function is onlyavailable in vehicles that can display informa-tion on the windshield with a head-up dis- play *.
WARNING
Detection ability may be affected by vehicle size, e.g. motorcycles, whichcan cause the warning light to come onat a shorter time interval than that setor cause the warning to be temporarilyabsent.
Very high speeds can cause the light tocome on at a shorter time interval thanthat set due to limitations in the rangeof the radar unit.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

Using engine braking instead of applying the brakes
Cruise Control regulates speed by lightly applying the brakes. On downgrades, it cansometimes be desirable to roll a bit faster andlet speed be reduced instead by engine brak-ing alone. The driver can temporarily disen-gage the Cruise Control braking function. To disengage CC:
–Press the accelerator pedal about halfway down and then release it.
> Cruise Control will automatically disen-
gage the automatic brake function and speed will only be reduced using theengine braking function.

The driver is advised to read all sec-tions in the Owner's Manual about thisfunction to learn of its limitations,which the driver must be aware ofbefore using the function.

The driver is always respon-sible for ensuring the vehicle is drivenin a safe manner, at the appropriatespeed, with an appropriate distance toother vehicles, and in accordance withcurrent traffic rules and regulations.
Adaptive Cruise Control regulates speed byaccelerating and braking. It is normal for thebrakes to emit a slight sound when they arebeing used to adjust speed. Adaptive Cruise Control always attempts toregulate speed smoothly. The driver mustapply the brakes in situations requiring imme-diate braking. For example, when there aregreat differences in speed between vehicles orif the vehicle ahead brakes suddenly. Due tolimitations in the radar sensor, braking mayoccur unexpectedly or not at all. Adaptive Cruise Control is designed to follow a vehicle ahead in the same lane and maintaina time interval to that vehicle set by the driver.If the radar sensor does not detect a vehicleahead, it will instead maintain the speed setby the driver. This will also happen if the speedof the vehicle ahead exceeds the set speed foryour vehicle.
CAUTION
Only a workshop may perform mainte- nance on driver support components – anauthorized Volvo workshop is recom-mended.
