There are, however, several safety features that might be what you're thinking of:
* Ignition Switch: This is the primary way to shut off the engine. It's usually located in the steering column.
* Fuel Pump Inertia Switch: This switch is designed to cut power to the fuel pump in the event of a collision, to prevent a fire. Its location varies by model year and may be under the dash, in the engine compartment, or even in the trunk. Your owner's manual should specify the location. This isn't a switch you would normally use to turn the car off.
If you're looking for a way to quickly shut down the car in an emergency, the ignition switch is your best and only practical option.
If you're having trouble finding the fuel pump inertia switch or have other concerns about safety features in your vehicle, consult your owner's manual or a qualified mechanic.
