  1. Open it wide to reach the fire
  2. Open it to let the smoke out
  3. Do not open it if you can avoid it ✔

Why: Opening the hood feeds the fire air. Turn off the engine as soon as you can and shoot the extinguisher through the louvers, the radiator or from underneath.

Huh, didn't know that: Pull off in an open area away from buildings, and never into a service station.
