Headlamp Lenses
Only use a mild soapy water solution when washing the
headlamp lenses. Do not use cleaning materials which contain
solvents.
Cleaning materials which contain solvents, i.e. tar remover,
gasoline, waxes or polishes, may damage the headlamp lens.
Under Hood Cleaning
Under hood cleaning using high pressure hoses or steam cleaners
should not be carried out. The electronic control module
connections and fuse boxes can be damaged by indiscriminate
use of high pressure cleaning equipment.
Polishing
Approximately twice a year, a good quality polish should be
applied to the body work and then buffed, using a soft lint free
cloth.
The alloy wheel rims should be treated with a cleaner which is
specifically manufactured for this purpose.
Bodywork Maintenance
Check the drain holes in the bottom face of each door
periodically and clear if necessary.

Maintenance and Technical Data
Upholstery, Trim, 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.
Caution: Certain types of clothing, such as denim and
vegetable tanned leather, are prone to 'dye transfer'. This can
cause discolouration in the leather. Make sure that the
affected areas are cleaned and re-protected as soon as
possible.
The seats and soft trimmed components of this vehicle are
covered in natural leather hide. 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.
These products may initially give an impressive result, but their
use will lead to rapid deterioration of the leather and will
invalidate the warranty.
Several times a year, a leather conditioner or preservative should
be used. Appropriate care materials are obtainable from your
Aston Martin Dealer.
The brushed and anodized aluminium trim should be cleaned
using a dry clean lint free cloth.
