If you find yourself in a situation where you need to turn on the heat in your car there are a few things you can do. First if you have an automatic transmission you can put the car into drive and then press the accelerator gently. This will cause the car to warm up faster. If you have a manual transmission you can put the car into first or second gear and then let off the clutch slowly. This will also help the car to warm up faster. Finally if you have a diesel engine you can turn on the glow plugs for a few minutes before starting the engine. This will help the engine to warm up and will make it easier to start.
