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

Airbag System E:m3^2?
Disposal of Live Airbags
Modu
les
removed/renewed by Aston Martin dealers
are to be deployed using the following procedure.
WARNING: Never use a customer's vehicle to
deploy airbags.
Equipment Required:
Link harness

'Slave'
battery
Safety goggles to BS 2092 grade 2 or equivalent
Rubber gloves to PrEN 374 class 2 or equivalent
Ear protectors
Particulate respirator to EN 149 grade FFP 25
Deployment cage
Note: If you do not
have access
to a deployment
cage,

please
contact Aston Martin
Lagonda
Limited
Technical

Support Department for advice.
Procedure
This procedure must be performed outdoors, away
from other personnel.
Remove any loose debris from around the airbag
and ensure that no flammable liquids are present.
Assemble the disposal cabinet and fit the airbag as
shown in figure 1 in line with the following
procedures:
a) Remove the mesh guard from the rig frame.
b) Attach the guard to the frame by bolting the
hinges to the frame.
c) Ensure the relevant plate is fitted and rotate into

position.

d) Fit and secure the airbag module onto the plate.
e) Clamp the plate down using the two toggle
clamps.
f) Close the mesh guard.
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 pink/black return wire.
Connect the 10 metre {33ft) link harness to the

airbag.

Ensure that no personnel are in the vicinity of the
cabinet.
5. Move 10 metres (33ft) and connect the link harness
crocodile clips to the 'slave' battery; the airbag will
deploy immediately.
6. Allow the unit to cool for at least 20 minutes.
7. Open the mesh guard and remove the deployed
airbag module.
Note: Should the
design
of your deployment
cage
differ
from that described above, please contact the cage
manufacturer for advice on mounting the airbag.
8. Seal the deployed module into a plastic bag ready
for disposal.
9. In the event of any problems or queries, contact
Aston Martin Lagonda Limited -Technical Services

Air Conditioning
Vacuum System •^^
Vacuum System The flaps in the cabin air distribution vents and the
water valve in the pipeline from the engine coolant
system to the heater matrix are all operated by
vacuum actuators. The vacuum forthese
is
supplied
by four solenoids mounted in pairs behind the front
footwell outlets. Each solenoid and its associated
pipe work is identified by a colour:
Defrost
Auto Re-circulation
Water valve
Centre vent
Green
Blue
Red
Black.
The vacuum supply pipes to the re-circulation and
centre vent actuators are fitted with restrictors in
order to slow down the operation of the flaps and
avoid hunting. The re-circulation flaps can take up
to 30 seconds to move to a new position.
Vacuum is piped to the solenoids from the engine
manifold through a reservoir. The solenoids are
energised by signals from the ECM in response to
demand ,sensing and feedback signals.
