Roll sensing of curtain shield airbags off
switch
The roll sensing of curtain shield airbags off switch
(RSCA OFFº switch) can turn off the curtain shield
airbags and seat belt pretensioners in a vehicle rollover.
This switch should only be used if inflation is not desired
(such as extreme off-road driving).
When you push the RSCA OFFº switch for a few seconds with
the ignition switch on, the RSCA OFFº indicator light comes
on and the roll sensing function is turned off. When you push
the switch again, the indicator light goes off and the roll sensing
function is turned on. (For details about the roll sensing
function, see SRS side airbags and curtain shield airbagsº on
page 167.)
In a severe side impact, the curtain shield airbags on impacted
side will inflate even if the roll sensing function is turned off.
(For details about the curtain shield airbags, see SRS side
airbags and curtain shield airbagsº on page 167.)In a severe frontal impact, the seat belt pretensioners will work
even if the roll sensing function is turned off. (For details about
the seat belt pretensioners, see ÐSeat belt pretensionersº on
page 149.)
If the ignition switch is turned to ACCº or LOCKº with the roll
sensing function off and then the ignition switch is turned back
to ONº, the roll sensing function will turn back on
automatically.
CAUTION
Before normal driving, make sure the RSCA OFFº
indicator light is off.
When the roll sensing function is turned off (and the
RSCA OFFº indicator light is on), the curtain shield
airbags and seat belt pretensioners will not work in
a vehicle rollover. Turning off the curtain shield
airbags and seat belt pretensioners reduces
occupant protection which your vehicle safety
systems can provide in accidents and increase the
likelihood of death or serious injuries.
