The Fire Suppression System is an Utility Slot certification available for every vehicle. When activated, at any health, it will repair a set amount of the vehicle's health over 5 seconds. This ability can save the driver and passengers lives provided that they are no longer being pursued by enemy forces. Depending on the upgrade level, the fire suppression system can be activated more often, and restored health over time is higher.
Additionally to the repair over time: if the vehicle is anywhere in a burning state (0< to ~10% health, model flashes red), fire suppression will, first, instantly bring the health to just above burning (into the flashing green). Meaning the greatest amount of health gained is when the vehicle is a hair away from exploding - a risk vs reward mechanic left up to the player to strategically decide upon.
When ready, the Fire Suppression System can be activated at anytime.
