ROPS

Volvo's Roll-Over Protection System has
been designed to reduce the risk of the car
overturning and to provide the best possible
protection in the event of an accident.
The system consists of:
• A stabiliser system, RSC (Roll Stability
Control) that minimises the risk of over-
turning during sudden evasive manoeu-
vres or the like or if the car skids.
• Increased protection for the driver and
passengers through a reinforced body,
inflatable curtains and seatbelt tensioners
in all seats. See also page 14 and
page 23.
The RSC system uses a gyro sensor which
registers changes in the car's lateral inclina-
tion angle. This information is then used to
calculate the risk for overturning. If a risk is
detected, the DSTC system is engaged, en-
gine speed is reduced and one or more
wheels are braked until the car returns to a
stable position.
For more information on the DSTC system,
see page 46 and page 125.

WARNING
Under normal driving conditions, the RSC
system improves the car's road safety, but
this must not be taken as a reason to in-
crease speed. Always follow the usual pre-
cautions for safe driving.
