Reproofs
Due to its construction the roof fabric will stay watertight without a
reproof. However to retain the appearance of the roof, to reduce
soiling and to improve the drying time Aston Martin recommended
that the roof has a reproof annually, by your Aston Martin Dealer.
Upholstery, Carpets and Seats
Warning: Fumes from cleaning solvents may be dangerous in
confined spaces. Make sure that the vehicle is well ventilated
and follow the manufacturer's printed instructions when using
these products.
The seats and soft trimmed components of this vehicle are covered in
natural leather hide.
11.46
In general, this natural leather upholstery requires little attention. The
seats should be brushed with a soft brush from time to time and may
be cleaned occasionally with a cloth damped in soap and water.
Do not use detergents, quick cleansers or furniture polishes.
Several times a year, a leather conditioner or preservative should be
used. Appropriate care materials are obtainable from your
Aston Martin Dealer.
Alcantara roof linings and other soft trimmed areas may be 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
To make sure that the restraint webbings are in proper working order,
regularly check the seat belts. Look for fraying, cuts, burns and similar
problems. Make sure that the latches and buckles function correctly.
If a seat belt is not in good condition or is not working properly,
consult your Aston Martin Dealer.
Any seat belt that has been worn during a serious collision should be
replaced by an Aston Martin Dealer.
Do not allow seat belts to be retracted until they are
completely dry.
