Rollover Protection System (ROPS)

Volvo’s Rollover Protection System utilizes the Roll Stability Control (RSC) function, which is designed to help minimize the risk of a rollover in emergency maneuvers or if a skid should occur.
RSC uses a gyroscopic sensor that registers the amount of change in the lateral angle at which the vehicle is leaning. Using this information, RSC calculates the likelihood of a rollover.
If there is an imminent risk of a rollover, the Dynamic Stability and Traction Control system (DSTC) is activated, power to the engine is cut and the brakes are applied to one or more of the wheels until the vehicle regains stability.
For additional information on DSTC, see page 149.
WARNING
The vehicle’s stability systems, including
ROPS and RSC, do not replace the driver’s
responsibility for operating the vehicle in a
safe manner. Speed and driving style
should always be adapted to the current
road, traffic and weather conditions. Posted
speed limits should always be respected.
