1. Ensure The Car Is Parked: Make sure the car is in a "Park" position. This is done by moving the gearshift lever to the "P" position.
2. Key Position: Turn the key to the "Accessory" or "On" position, but do not start the engine. This means the dashboard lights should be on.
3. Press the Brake Pedal: Press the brake pedal down firmly before attempting to shift gears.
4. Shift Gears: While keeping the brake pedal pressed, you should be able to move the gearshift lever through the different gears ("Drive", "Neutral", etc.).
It's important to note that shifting gears in automatic transmission cars with the engine off may have certain limitations. For example, you might not be able to shift into all gear positions, and the car might not respond or move as if the engine is running.
If you're not familiar with your car's automatic transmission or have any doubts, it's always best to consult the owner's manual or seek guidance from a qualified mechanic.
