Roll stability control (RSC)
Volvo's Roll Stability Control (RSC) is a stability
system 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 stability system
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.
WARNING
The vehicle’s stability systems, including 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 condi-
tions. Posted speed limits should always be
respected.

Limitations
On steep downslopes, the Speed limiter's braking
capacity may not be sufficient and the set maxi-
mum speed may be exceeded. If this happens,
Speed limit exceeded
will be displayed in the
instrument panel to alert the driver.
This message will appear if the set maximum
speed is exceeded by more than approx. 2 mph
(3 km/h).
