Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fire Suppression System: Notes
- 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 is designed to help reduce the risk of fire in high speed rear impacts. The fire suppression system deploys chemicals designed to suppress the spread of fire or potentially extinguish a fire, thereby providing more time for occupants to escape from a crashed vehicle.
The fire suppression system can be activated:
- automatically when a high speed, high energy rear impact has occurred.
- manually when other situations require fire suppression.
In the event of a fire suppression system manual deployment, the fire suppression manifold 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 vehicle underbody with water, or soap and water. Manual deployment should have no effect on vehicle handling.
The fire suppression system consists of the following components:
- Fire suppression system module (FSSM)
- Fire suppression manual switch
- Fire suppressors
- Fire suppression manifolds
- Fire suppression system indicator (part of the instrument cluster [IC])

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
