What is the button on the side of my gear shift?

The button on the side of your gear shift is a common feature in many modern vehicles, serving an important function in the operation of your car's transmission. This article will provide a detailed explanation of what this button is and how it is used.


What is the Button on the Side of the Gear Shift?


The button on the side of the gear shift, often referred to as the "shift lock release" or "shift interlock", is a safety mechanism designed to prevent the accidental shifting of the transmission. This button is typically located on the side or front of the gear shift lever, and it must be pressed in order to move the gear shift out of the "Park" position.


How Does the Shift Lock Release Work?


The shift lock release button is connected to a small mechanism inside the transmission that physically prevents the gear shift from being moved out of "Park" unless the button is pressed. This is a safety feature that helps to ensure the vehicle cannot be accidentally shifted into gear while the driver is not paying attention or when the vehicle is not in a safe condition to be driven.


When to Use the Shift Lock Release



  • When starting the vehicle: The shift lock release button must be pressed in order to move the gear shift out of "Park" and into another gear, such as "Drive" or "Reverse".

  • If the vehicle loses power: If the vehicle's battery dies or there is a electrical issue, the shift lock release button may need to be pressed in order to shift the transmission out of "Park" and move the vehicle.

  • In an emergency: In rare situations, the shift lock release button may need to be used to quickly shift the transmission out of "Park" in an emergency situation.


It's important to note that the shift lock release button should only be used when necessary, as it is a safety feature designed to prevent accidental shifting of the transmission.
