Starting a car by pushing it (also known as push starting or bump starting) is typically done on vehicles with manual transmissions. Here's how you can push start a car:

1. Make sure the ignition key is turned to the "on" position.
2. Put the car in second gear (if your car is front-wheel drive) or first gear (if your car is rear-wheel drive).
3. With the help of one or two people, push the car to get it rolling at a speed of about 5-10 mph.
4. Once the car is moving, quickly depress the clutch pedal.
5. As the car gains momentum, release the clutch pedal quickly.
6. If the push start is successful, you should feel the engine starting and the car should begin to run.

Remember, push starting a car can be a temporary solution and may indicate a problem with the battery, starter, or alternator. It's best to have a professional mechanic inspect your vehicle to identify and fix any underlying issues.
