Airbag System
Airbag (Supplementary Restraint System)
Repair Procedures
Description
Two airbaes are fitted to the 97 model year DB7.
The drivers airbag is located in the centre of the
steering wheel (Fig 1-1), the passenger airbag is
located behind the fascia panel (Fig 1-2).
Figure!. Airbag Locations
The following procedures and safety precautions
must be adhered to while handling, installing and
testing airbag modules. Failure to observe these
precautions could cause the airbag to inadvertently
deploy with the risk of personal injury.
The procedures and precautionary guidelines
conform to the 'Handling and storage - The
Explosives Act 1875 & 1923' and to the 'Health and
Safety at Work Act - 1974' or local guidelines as
appropriate.
Safety Precautions and Warnings
Handling Undeployed Airbags
The electrically actuated airbag module contains
sodium azide and sodium nitrate which are
poisonous and extremely flammable substances.
Their contact with
acid,
water or heavy metals may
produce harmful, irritant gases or combustible
compounds.
The airbag module is non-serviceable and must not
be dismantled, punctured, incinerated or welded.
WARNING: Do not attempt any repairs or
electrical measurements on the airbag module.
Never measure the resistance of the airbag module,
as this may cause the airbag to deploy. Suspect
modules must be returned to Aston Martin Lagonda
Limited,
or their importer for replacement.
Tampering or mishandling can result in personal
injury.
Keep away from heat, sparks and open flames. Do
not store at temperatures exceeding 93°C (200°F).
Keep away from electrical equipment as electrical
contact may cause ignition.
Do not drop or impact the airbag module. Always
position the module 'cover-up'.
Ensure that the module connector is protected to
prevent damage. Never carry the airbag module by
the wires or connector.
Store modules in a secure lockable cabinet.
Never position material over the undeployed
module which could be projected and cause injury
in the event of inadvertent deployment.
Do not wrap arms around the module when carrying
and always carry the module with the cover and
vents facing away from the body to avoid personal
injury in the event of inadvertent deployment.
The chemical propellant mixture deploying the
airbag is a solid and therefore inhalation exposure
is unlikely even if the module is ruptured without
deployment.
As far as practical, avoid skin contact
with,
or
ingestion of, the materials present after combustion.
Exposure to high concentrations of propellant
mixture may cause headache, nausea, blurred
vision,
faintness, cyanosis, lowering of blood
pressure, tachycardia and shortness of breath.
WARNING: Sodium azide has been listed as an
'Extraordinary Hazardous Substance or
Carcinogen' by the state of
Massachusetts,
USA.
Sodium azide has been listed on the
'Right
to Know
Hazardous Substance
List'
by the state of New
Jersey and is also regarded as a 'Special Health
Hazard Substance' by the state. The propellant
mixture is sensitive to premature ignition by
electrical sources if not properly protected and
isolated.

Emergency First Aid Procedures
If the airbag is ruptured without deployment and
exposure to the propel lant mixture occurs, observe
the following first-aid treatments:
• Ingestion - Do not induce vomiting and seek
prompt medical attention.
• Skin contact - Immediately wash skin with soap
and water and seek medical attention.
• Eyes - Immediately flush eyes with water for at
least 20 minutes and seek prompt medical
attention.
• Inhalation - Immediately move victim to fresh
air and seek medical attention.
• Physical trauma,
e.g.
burns, abrasions, or impact
due to premature ignition or deployment of the
inflator assembly - Treat symptomatica
I
ly and
seek prompt medical attention.
Safety Procedures
Handling Deployed (Fired) Modules
See 'Emergency First Aid Procedures'
Prevent contact of the inflator with liquids,
combustibles and flammable materials. Failure to
follow these instructions could result in chemical
burns and personal injury.
Ensure that the modules are cool before handling.
After deployment, the airbag surface contains small
deposits of sodium hydroxide which can cause
irritation to the skin and eyes.
When handling deployed airbags, always wear
rubberglovestoBS1651 grade 2 or equivalent, and
chemical resistant goggles to BS 2092 grade 2 or
equivalent.
After handlingdeployed airbags, immediately wash
hands and exposed skin surface areas with mild
soap and water.
Handling Undeployed Damaged Modules
The material inside the module is hermetically
sealed and is completely consumed during
deployment.
No attempt shou
Id
be made to open the modu
le
as
this leads to a risk of exposure to sodium azide.
In the unlikely event of a gas generator being
damaged,
it must be examined by trained personnel
before any attempt is made to remove and/or
deploy.
Full protective clothing must be worn when dealing
with any spillage.
Ruptured units must be stored away from acids,
halogens, heavy metals and metal salts. Damaged
units may produce hydrazoic acid if exposed to
liquids.
Failure to comply with these instructions may result
in fire, noxious fumes and severe personal injury or
death.
Fire Hazard Information
Thermal decomposition or combustion may
produce dense smoke and other dangerous fumes
which infiresituationsformahighlytoxicexplosive.
In the event of a fire, the surrounding area must be
evacuated and all personnel kept well upwind of
the area.
Full fire fighting protective gear and a self contained
breathing apparatus operating in positive pressure
mode must be worn for combating fire. Material
near the fire must be cooled with water spray to
prevent ignition.
Fires should be allowed to burn themselves out if
not threatening to life or property, if fire
is
threatening
to life or property, use copious quantities of water
to extinguish.
Ventilation
Local exhaust ventilation designed by
a
professional
engineer should be provided if vapours, fumes or
dusts are generated whilst working with the airbag
module.
Respiratory Precautions
To prevent the inhalation of dangerous fumes and
dusts,
an approved mask should be worn.

Airbag System
Eye Protection
Chemical protective goggles are recommended
where there is a possibility of eye contact with the
propellant. Safety glasses with side shields are
recommended for all other operations.
Protective Clothing
Approved protective gloves, overalls and shoes/
boots should be worn.
Handling and Storage Precautions
Do not store airbag modules near live electrical
equipment or circuitry. Store in a dry environment
at ambient temperatures.
Good housekeeping and engineering practices
should be employed to prevent the generation and
accumulation of
dusts.
Store in compliance with all
local state and federal regulations.
Driver and Passenger Airbag Modules
Assembly/Removal/Service Instructions
WARNING: In the event of a vehicle impact where the
airbags and the seatbeltpretensioner (if fitted) are
deployed, the following actions MUST be
performed:
Check the condition of the seatbelts, steering
wheel,
steering column, all connections to airbags,
and the column switchgear connectors for integrity
and damage. If in any
doubt,
replace suspected
parts for new parts.
Replace both crash
sensors,
the
safing sensor
and
the seatbelt pretensioner module (if fitted).
On completion of all repair procedures, switch on
the ignition and check that the
Airbag/SRS
warning
light comes on when the ignition is switched on
and extinguishes after approximately six seconds
indicating satisfactory completion of the airbag
and pretensioner
system
self
tests.
WARNING: Before starting
work,
ensure
that the ignition
switch is in position 'O' and the ignition key is
removed.
Disconnect the battery negative lead
within 12 seconds of switching off the ignition to
prevent the alarm system triggering.
As the airbag control module is equipped with a
back-up power source and due to the risk of the
airbag being inadvertently deployed, wait one
minute or longer after disconnecting the battery
before starting work on the airbag module.
• Disconnectingthe battery negative cable cancels
the memory for the 'one-touch' window down
system and stops the vehicle clock. Reset the
window memory and the clock when work is
completed.
• Never use airbags from other vehicles, always
use new parts.
• After work is completed, reconnect the battery
and perform the airbag warning light check
• Never use electrical probes to check voltage or
electrical resistance of the airbag modules.
• Disconnect the airbag before carrying out any
work on, or in the vicinity of the module, or
when using electric welding equipment.
• Always ensure that the battery negative lead has
been disconnected for at least one minute before
commencing any removal procedure.
