The stability system RSC
minimises the risk of
overturning, for example during a sudden evasive
manoeuvre or if the car skids.
The RSC system registers if and how much the
car's lateral inclination changes. This information
is used to calculate the risk of the car overturn-
ing. If the car is at risk, its electronic stability con-
trol system engages, the engine torque is
reduced and one or more wheels are braked until
the car has regained its stability.
WARNING
Under normal driving conditions, the RSC sys-
tem improves the car's road safety, but this
must not be taken as a reason to increase
speed. Always follow the normal precautions
for safe driving.
