brushed with a soft brush. Stains from water based substances
such as coffee, tea or soft drinks should be cleaned as soon as
possible with mild soap and water.
Consult your Aston Martin Dealer for instructions on the removal
of more difficult stains such as oil, grease or ballpoint ink.
Carpets should be cleaned regularly with a vacuum cleaner. Any
stains or grease marks should be removed with a good quality
solvent suitable for use on carpets.
Care and Maintenance of Seat Belts
Caution: Do not allow seat belts to be retracted until they
are completely dry.
To make sure that the restraint webbings are in correct working
order, regularly check the seat belts. Look for fraying, cuts, burns
and similar problems. Make sure that the latches and buckles
operate correctly. If a seat belt is not in good condition or is not
working correctly, consult your Aston Martin Dealer.
Any seat belt that has been worn during a serious collision should
be replaced by an Aston Martin Dealer.
To clean the seat belts, use mild soap and water; do not use
bleach, solvents or dyes, as they can weaken the material. Allow
the seat belts to dry thoroughly before use.

Convertible Roof Cleaning
Caution: Do not leave the roof in the lowered (folded)
position for extended periods of vehicle storage. Permanent
damage to the convertible roof fabric may occur including
soiling and fading along folds.
Caution: Do not use automatic vehicle washes. Brushes,
detergents and pressurized 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.
To maintain the appearance and condition of the roof fabric the
cleaning recommendations given below should be followed. This
is of particular importance in the case of light coloured roof
fabrics.
Always remove bird droppings as soon as possible. The organic
acids in bird lime can adversely affect the roof fabric.
Carefully vacuum clean the roof fabric to remove any loose
particles. Gently, and evenly, wash the roof fabric using a mild
soap solution and a soft brush.
A hard brush will damage the fabric fibres.
Rinse the roof fabric thoroughly with clean water to remove any
traces of soap. Allow the roof fabric to completely dry before
operating the roof.
