3. A firm strike on the cover (about 20 lbft [89 N•m] of force) will
deploy the system any time the key or engine is turned on.
In the event of a manual deployment, nozzles will deploy to near ground
level and the underbody of the vehicle will be covered with suppressant
fluid. The suppressant contains no hazardous materials (but may cause
minor skin or eye irritation) and can be readily cleaned up by flushing
the underbody with water (or soap and water). Manual deployment
should have no adverse affect on vehicle handling; however, caution
should be exercised in moving the vehicle as ground clearance will be
compromised by the deployed nozzles. Because of reduced ground
clearance, the vehicle should not be driven through an automatic car
wash with nozzles in the deployed condition.
The fire suppression system is a single use system - all major
components will have to be replaced in the event of a manual
deployment.
Figure A
The approved ISO symbol for fire suppression is shown in Figure A. This
symbol is printed on the manual activation switch and on the diagnostic
telltale on the instrument cluster.
The system automatically performs a diagnostic check self check and
momentarily lights the cluster lamp when the key is turned on. If the
diagnostic lamp stays on refer to the appropriate sections of the Ford
service manual for further diagnostic and service procedures.
The system is active any time the key or engine is turned on following
the diagnostic check.
The system has been designed and tested to withstand a 75 mph
(120 km/h) 50% off-set rear impact by Taurus-sized vehicle. However, in
some crashes, including very high-energy crashes, the fire suppression
system could be so damaged by the crash forces that it cannot deploy.
Like any vehicle component, the fire suppression system cannot
withstand any and all crashes. No vehicle can eliminate the risk of fires.
You should not consider the vehiclefireproofbecause it is equipped
with a fire suppression system.
