Another way is to use the emergency release located inside the car near the floor. In addition, another method is to use the key to release the parking brake. To do this, insert the key into the hole next to the gear shift and turn it counterclockwise until you hear a click. Finally, you can use the button on the dashboard next to the steering wheel. Press this button and hold it down until you hear a beep. This will release the parking brake.
The emergency brake handle is located on the front corners of the car, low to the ground. Also, there are two cables attached to this handle. These cables run along both sides to the back brakes of your vehicle. Pulling up on these cables will release your parking brake.
