Fire Suppression System: Notes

WARNING: The fire suppression system backup power supply must be depleted before lifting the vehicle or when repairing or replacing any of the following:

Fire suppression system components
Components located near the fire suppression manual switch
Fuel tank and components located near the fuel tank
Rear axle and components located near the rear axle

To deplete the backup power supply, disconnect the battery and wait at least 1 minute. Be sure to disconnect all auxiliary batteries and power supplies (if equipped). Failure to follow these instructions may result in serious personal injury .

The fire suppression system helps reduce the risk of fire in high speed rear impacts. The fire suppression system deploys a fire suppressant chemical to suppress the spread of fire or potentially extinguish a fire allowing occupants more time to escape from the vehicle.

automatically during a high speed rear impact.
manually from the fire suppression manual switch.

In the event of a fire suppression deployment, the fire suppression manifold nozzles deploy downward and discharge a fire suppressant chemical under the vehicle and around the fuel tank.

NOTE: After system deployment, the fire suppression manifold nozzles may need to be secured in the up position before driving the vehicle through an automatic car wash, or they may come in contact with the automatic car wash components causing damage to the fire suppression nozzles and vehicle.

The fire suppressant chemical contains no hazardous materials (but can cause minor skin or eye irritation) and can be readily cleaned up by flushing the vehicle underbody with water or soap and water. Manual deployment should have no effect on vehicle handling.

NOTE: In the event of a fire suppression system deployment, new fire suppression components must be installed. The fire suppression manual switch is only replaced if the switch cover was damaged during a manual activation event.

The fire suppression system consists of the following components:

Fire Suppression System Module (FSSM)
Fire suppression manual switch (located in the overhead console)
LH and RH external fire suppressors actuators (if equipped)
LH and RH fire suppressors
LH and RH fire suppression manifolds
Fire Suppression Indicator Lamp (FSIL) (part of the Instrument Cluster (IC))
