3. A firm strike on the cover (about 20 lb–ft [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 vehicle “fireproof” because it is equipped

with a fire suppression system.
