152 TwinTop
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 sat head
restraints. The anti-roll bars are fixed or
deployable depending on vehicle variant.
Fixed anti-roll bars
are secured to the vehicle bodywork.
Deployable anti-roll bars 3
are 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 roof 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.
