Spillage and Leakage
If material is spilled or released, contact Aston
Martin Technical Support for advice on clean-up
procedures. All personnel must be kept away from
the contaminated area.
Do not dispose of contaminated propellant or
water into storm or sanitary sewers, ground water
or
soil.

Spills may be reportable to state and/or federal
authorities.
Materials must be disposed of by incineration or
chemical oxidation under carefully controlled
conditions by specially trained individuals and in
accordancewith local stateandfederal regulations.
Scrapping Vehicles with Live Airbags
when scrapping a vehicle with live airbags, first
deploy the airbags in accordance with the following
procedure. This procedure assumes that the airbag
wiring is undamaged
See Handling/Safety Information.
If the airbags are to be removed, see the airbag
module assembly/removal/servicing instructions.
Equipment required:
Four insulation displacement connectors
(scotch locks).
Charged 'slave' battery.
Two 10 metre lengths of
1
mm^ wire fitted with
crocodile clips on one end.
Procedure
WARNING: The deployment procedure must be
carried out outdoors away from other personnel.

1.
Remove any loose debris from around the airbag
modules and ensure that no flammable liquids are
present.

2.
Disconnect the vehicle battery.
WARNING: Always connect to the airbag
first,
as

the bag will deploy immediately on connection to
the battery.
3. Remove the passenger side airbag deployment
door and underscuttle panel.

4.
Remove the drivers side underscuttle panel.
5. Disconnect the airbag connector for the spiral
cassette under the fascia and at the wire (drivers

side).

6. Locate the harness connectors and cut the wires
leading from the airbag just above the mating plug
(passengers side).
Note: The harness connected between the driver's

airbag
and the connector
has
one red
feed
wire and
one

grey/orange return
wire.
The
harness
connected between
the
passenger's
airbag and the connector
has
one blue/

orange
feed wire and one
pinl return wire.

Body and Trim
Body Repair
Precautions
Paint
Ensure that there is efficient ventilation at all times. Paint spraying should be confined to spray booths.
Anyone with a history asthma should not be engaged in any process which involves the use of isocyanates.
Any operator working inside a spray booth where isocyanates are present must use air-fed breathing equipment.
Supplied air to the visor should be fed at the recommended pressure and filtered to remove oil, water and fumes.
Operators involved in handling, mixing or spraying should wear protective clothing, gloves and goggles to avoid
skin and eye contact. A Paticle mask or canister typr respirator should be worn when sanding.
Applied heat
When welding, flame cutting or brazing and so on, goggles, a mask or fume extractor and flameproof protective
clothing should be used always.
It is especially important when working with polyurethane compounds to use air-fed breathing equipment.
Ensure that at all times the appropriate fire fighting equipment isavailableand that personnel are trained in its use.
Metal repair
Wear appropriate eye and hand protection when sanding, drilling, cutting, chiselling, flatting or welding. Wear a
face mask or air-fed visor when sanding or flatting either body solder or
fillers.
When a soldering operation has been

completed,
remove swarf from the work area and wash your hands thoroughly.
General Repair Notes
The following precautions should be noted before any work is carried out:
• disconnect the vehicle battery ground
lead,
taking note of the reconnection procedures
• Make sure that you have read and understood the safety related procedures in this section.
Caution:
Electric arc
welding must not
be
used on the
vehicle as the high
voltages produced by
this process
will
cause
irreparable

damage
to the electrical control and
microprocessor
systems.

All trim and electrical components in the locality of the repair must be removed or disconnected prior to panel
removal or replacement.
Welding and Gas Process Special Notes
Resistance spot welding, MIG welding and all gas processes may only be carried out on bare, unpainted or unplated

metal.
The flanges of panels, which are to be welded together, must be clean, corrosion free and treated as
appropriate with either weld-through or inter-weld sealer.
The resistance spot welding equ ipment used in vehicle repair does not always produce
a
weld of
equ
ivalent strength
to that produced in manufacturing. This means that a single row of spot welds should be spaced on a pitch of 19-
25 mm, which will usually result in more spot welds than found in the original factory joint.
Use a resistance spot weld cutter to remove resistance spot welds. Where a new joint is to be MIC welded, cut the
old resistance spot welds from the panel that is to be retained; the resulting holes are then used for plug welding.
Suitable holes may be drilled or punched as follows:
• 8.0 mm for sections up to 1.5 mm thickness
• 10.0 mm for thicker sections.
Always refer to the welding equipment manufacturers diagrams and tables for the relevant procedure.

Cleaning of Alcantara Trim
Cleaning of Alcantara Trimmed Roof Lining and Interior Components
Recommendations

1.
Clean the stain immediately.
Clean the stain working from the edge to the centre of the spot to prevent a ring forming.
Delicately remove most of the dirt with a blunt scraper and immediately blot the spot with a clean white cloth.
Once you've identified the type of stain, follow the instructions in the spot removal chart.
Never pour a solvent directly on the spot; instead pour the solvent on a clean cloth.
After you've applied the spot remover, remove it with a dry clean cloth. Afterwards, brush the area against the
material nap.
7. Let the spot dry. Do not sit on a humid part. Afterwards, vacuum the spot with a vacuum cleaner.

Cleaning Product and
Cleaning Method
Wash with mild soap, then blot with denatured alcohol
Blot with lukewarm water (max 50°C) and denatured alcohol at 3%
Washwithmildsoap. If the stain persists, blot with denatured alcohol or ammonia diluted
at 10%.
Blot with lukewarm water (max 50°C) or with ammonia diluted at 5%.
Oil Paint - Blot with ethyl alcohol then wash with mild soap.
Water Based Paint - If the stain is fresh, blot with cold water. An old stain is very difficult
to remove, consult a specialist.
Apply ethyl alcohol or perchloroethylene, then wash with mild soap. If the stain persists,
use ammonia diluted at 5% or denatured alcohol.
Blot with lukewarm water (max 50°C) then wash with mild soap.
Blot with acetone.
Remove as much as possible with a paper towel. Blot with a solution of 30% denatured
alcohol and 70% water, then wash with mild soap. Lemon juice also gives good results.
Blot with lukewarm water (max 50°C). If the stain persists, use ethyl alcohol or
perchloroethylene
Blot with denatured alcohol, then wash with mild soap.
Blot with perchloroethylene and denatured alcohol.
Blot with water and vinegar (50%), then wash with mild soap.
