What is the l on my gear shift?

As an AI language model, I do not have access to the specific gear shift you are referring to. But generally, the "L" on a gear shift means "Low" gear. It is typically used in vehicles with an automatic transmission, allowing the driver to limit the gear range to only low gears, providing more power and torque for better acceleration and towing. The "L" gear is usually used in situations where the vehicle needs more power, such as climbing steep hills or towing heavy loads.
