15.1.13 Spillage and Leakage
If material is spilled or released,contact Jaguar Service for clean up procedures. All other personnel must be kept away
from contaminated area.
Do not dispose contaminated propellant or water into storm or sanitary sewers, ground water or soil.
Spills may be reportable to local state,
and/or federal authorities.
Material should
be disposed of by incineration or chemical oxidation under carefully controlled conditions by specially
trained individuals in accordance with local State and Federal regulations.

15.1.14 Scrapping Vehicles With Live Airbag(s)
When scrapping a vehicle with a live airbag, first deploy the
airbag in accordance with following procedures. This
procedure assumes airbag wiring is undamaged.
See Handling
/ Safety information.
If the airbag is
to be removed see Airbag Modules Assembly/ Removal/Service Instructions.
Equipment required: Insulation Displacement Connectors
(IDC) (Scotchloks) (two-off), battery, two-off ten meter
lengths of lmm2 wire fitted with crocodile clips at one end. (See Fig. 1).
WARNING: THE DEPLOYMENT PROCEDURE SHOULD BE PERFORMED OUTDOORS AWAY FROM OTHER
PERSONNEL.
Remove any loose debrisfrom around airbag and ensure no
flammable liquids are present.
Disconnect the vehicle battery. Fig. 1
Link harness conn&ion & deployment method
WARNING:
ALWAYS CONNECT TO AlRBAG FIRST, AS THE BAG WILL DEPLOY IMMEDIATELY ON CONNECTION TO
THE BATTERY.
Remove passenger side and driver side under-scuttles / knee bolster.
. Disconnect the airbag connector under the facia.
. Look for the yellow harness connectors and cut the wires originating from the airbag just above the mating plug.
w: The harness connected between the driver's airbag and the yellow connector has one red/purple feed wire and
one pinkbrown return wire.
The harness connected between the passenger's airbag and the yellow connector has two
red/purple feed
wires and one pinwpurple return wire.
Pass a 10 meter (33ft) link harness containing two lmm2 wires through the window aperture, and connect using an
. Close all doors, leave window with lead open.
. Ensure no personnel are in the car or in the area around the car.
. Move back 10 meters (33ft) and connect harness crocodile clips to battery: the airbag will immediately deploy.
Allow the unit to cool for at least 20 minutes. Cooling modules should be continuously monitored to ensure heat
