Roll Stability Control - Volvo XC90 Owner's Manual

SAFETY
Do not leave any objects on the floor behind or under
the front seats or in the seat row behind the driver's
seat/passenger seat that may prevent WHIPS from
functioning.
WARNING
Do not squeeze rigid objects between the
rear seat cushion and the front seat's back-
rest.
WARNING
If a rear seat backrest is folded down, the cor-
responding front seat must be moved forward
so that it does not make contact with the
folded backrest.
Seating position
For optimum protection from WHIPS the driver
and passenger must have the correct seating
66
position and make sure that the system's func-
tion is not obstructed.
Set the correct seating position in the front seat
before driving starts.
Driver and front seat passenger should sit in the
centre of the seat with as little space as possible
between the head and the head restraint.
WHIPS and child seats
The protection provided by the car to children
seated in a child seat or on a booster cushion is
not diminished by WHIPS.
A child seat/booster cushion can be placed on
the front passenger seat provided that the car
does not have an activated airbag on the front
passenger side.

Roll Stability Control

Roll Stability Control (RSC) is a stabiliser sys-
tem that minimises the risk of overturning, for
example during sudden evasive manoeuvres or if
the car skids.
The RSC system uses a sensor which registers
changes in the car's lateral inclination angle. This
information is used to calculate the risk of the car
overturning. If a risk exists, the car's electronic
stability control engages, engine torque is low-
ered 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.
