Rollover protection system
To optimise safety in the event of a
rollover, the Astra TwinTop is equipped
with reinforced windscreen frame and
anti-roll bars behind the rear seat head
restraints.
The anti-roll bars are fixed or deployable
depending on vehicle variant.
Fixed anti-roll bars
are secured to the
vehicle bodywork (see illustration).
Deployable anti-roll bars
3
Located between the rear head
restraints and the boot lid in such a way
that they are out of sight. In the event of
a rollover, head-on collision or side
impact, the anti-roll bars deploy
upwards within milliseconds.
The convertible hardtop must not be
operated if the anti-roll bars have been
deployed. A continuous warning will
sound if the switch is actuated.
The airbag control indicator
v
illuminates if the anti-roll bars have been
deployed.
Wind deflector
3
With the wind deflector installed,
turbulence, draughts and noise in the
passenger’s compartment are reduced
when the roof is open.
The rear seats cannot be occupied when
the wind deflector is in place.
Place no objects on the wind deflector.
The wind deflector is folded together in a
stowage compartment
3
in the luggage
compartment beneath the floor hatch.
If vehicle is fitted with a spare wheel
3
,
the wind deflector is in the luggage
compartment.
For instructions on how to fit and remove
wind deflector, see Owner’s Manual.
