Roof Maintenance; Deployable Rollbars - Aston Martin DB 9 2010 Manual

Roof Maintenance

If the Roof is left for prolonged periods in the lowered position
(folded), in certain circumstances (i.e. a wet or dirty Roof) permanent
soiling along folds may occur in the Roof fabric. Do not leave the Roof
in the lowered position for longer than necessary.
Do not use automatic vehicle washes. Brushes, detergents
and pressurised water jets may damage the Roof fabric.
Do not use power washers. Jets of water may damage the
weather seals and the Roof fabric.
Do not use spot cleaners, chemical diluents or any organic
cleaners. If in doubt, contact your Aston Martin Dealer.

Deployable Rollbars

Warning: Do not attempt to service or modify the deployable
rollbar system.
Warning: Do not allow any person to sit on the deployable
rollbar covers at any time.
Warning: Do not attempt to reset the deployable rollbar
system after it has deployed. It is a 'single use' system, if reset it
will not deploy a second time.
If the Roof is raised after the rollbars have deployed the
rollbars will break through the rear glass.
If the Roof is not stowed the deployable rollbars will break
through the rear glass.
Do not place any objects on the top of the deployable rollbar
covers.
Do not attempt to raise or lower the Roof after the deployable
rollbar system has deployed.
Extreme manoeuvres may cause the system to predict a roll
over and deploy the rollbars for protection of the occupants. If
such driving events are anticipated by the customer (e.g. Track
day driving) the Roof should be retracted to allow the rollbars to
deploy without damaging the vehicle.
The deployable rollbar system and the airbag system react
independently. The deployable rollbars and the airbags may deploy
together or alone, depending on the type of impact.
The Volante is equipped with a deployable rollbar system, which is
in addition to and independent of the airbag system.
