You might be familiar with common car gear modes like “Drive” and “Park” on your gear shift controls, but what does the L a gear shift symbol? The “L” on the gear shift stands for “Low.” What is the “L” gear used for? When you want the engine power to be high and the vehicle speed to be low, you use the low gear. This lessens the strain on your brakes while enabling you to utilize the full potential of your vehicle in scenarios like towing and hilly driving.

What’s the “L” For?
While the above four transmission states are the most commonly used, some car manufacturers provide an “L” setting as well.
L stands for “low” gear, which translates to a gear setting of 1 or 2 (if you know how to drive a manual transmission) in most vehicles.
The transmission of a car won’t shift normally when it is in low gear. Instead, your transmission will continue to operate in low gear, allowing less fuel to enter the engine and reducing your overall motor power. In return, you’ll receive more engine torque.
By essentially giving your wheels a little more raw force rather than speed when you press down on the gas pedal, the engine can be advantageous in some situations.
When to Use the ‘L’ Position
Generally speaking, lower gears are present for better power delivery when accelerating or tackling hills, while higher gears are present for better fuel economy, reduced noise, and reduced engine wear at higher speeds. Whatever the transmission’s gear count, this holds true. But more importantly, using lower gears to slow down is also an option.
When descending steep hills, Low, which prioritizes the use of the lower gears in the transmission, can be helpful because it keeps the engine spinning faster even when the gas pedal is not being depressed. Because of this, there is more room for engine braking, which slows the car down without using the brakes, which could cause them to overheat and fade. This was probably the Low position’s main function in the early days of automatics.

Although shifting to a higher gear (which the transmission may otherwise want to do) could tax the engine and cause you to slow down and lose valuable momentum, Low can also be helpful when navigating steep hills, sand, or deep snow.
Your Vehicle’s Gearshift – An Overview
A car’s gearshift is a vital component for the transmission: the major car part that “transmits” engine power and torque can be used by your car’s wheels to create motion. Nowadays, the majority of drivers use automatic transmissions, which can quickly determine through sensors which gear is necessary given the situation and driving conditions.

Here’s a more detailed breakdown of the transmission and its purpose:
- Your engine runs and simultaneously spins a part called the crankshaft
- The crankshaft produces the power your car needs to move its wheels
- Your car’s automatic transmission will adjust the gearshift and transmit the crankshaft’s power at different levels of torque
- The more torque that is produced (and the lower the gear), the more power your wheels have and the slower they turn
Without the transmission to control how much power is sent to the wheels, your engine would become erratic.

P, R, N, D, and L – the Gears of An Automatic Transmission
You’ve no doubt noticed that most vehicles have a gearshift control with the letters “P, R, N, S” and “L.” These all represent various operational modes and different states for your transmission.
- P stands for park
- R stands for reverse
- N stands for neutral
- D stands for drive
For a variety of purposes, all of these modes are frequently used. The drive is used for regular driving, Park is used to keep your car stationary, Reverse is used to back up your car, Neutral is used if you ever need to push or pull your car without the engine running.
Does Your Car Shift into Low Gear Automatically?
Yes, in fact, whenever you start your car, it always moves through low gear before gradually increasing speed. Whenever you park or stop at a street intersection without turning the car off, your car also shifts into and out of low gear.
Low gear is required to prevent your engine from spinning your wheels out of control and causing you to travel too quickly for safe driving.
Automatic transmission vehicles handle this process for the driver, relieving them of the burden of gear-shifting while navigating city streets.
When Should You Use the “Low” Setting on Your Gearshift?
Some cars allow their drivers to manually shift into low gear, whereas an automatic transmission might shift you back down and above low gear without your input. But why do this?
Use your lowest gear when possible to take advantage of the extra torque it gives your wheels in certain circumstances. For example, low gear can be beneficial when:
- You have to pull trailers, cars, or boats. Remember that your car has more pulling or pushing power when it is in low gear. Note that before using low gear, you should always refer to your car’s owner’s manual because it will list the highest safe speed that you shouldn’t go over.
- Navigating through snow and ice. Your car will always move more slowly and powerfully when you downshift, which can help your wheels grip the road in slick conditions and keep you from spinning out of control.
- Like when traveling through the mountains, driving up and down hills If you don’t engage a low gear, it can be challenging to climb steep inclines without overtaxing your engine. Additionally, because you won’t need to brake as hard, driving in low gear can be advantageous when going down a hill.

Wrap Up
Ultimately, the “L” setting on your gearshift is just one more tool at your disposal to ensure safe driving and to make sure that you use your engine’s power appropriately based on your circumstances. Although you shouldn’t always drive in low gear, you should become familiar with how your car operates in these conditions so that you are prepared to use it to its full potential when the occasion arises.
FAQs
What Does S Mean on a Car Gear Shift
If you’re looking for a quick answer, the S on a gear shift stands for Sports Mode.
What Does the I Mean on a Gear Shift
The oddly named “I” gear position is a different abbreviation for a very common feature. The letter signifies the Spark’s Intermediate gear on the shifter; it performs the same function as the more common “2” used elsewhere.
What Does the 2 Mean on a Gear Shift
Just like the L mode, the 2 mode means that the engine will only use the first 2 gears of your car. In order to obtain the required pull from the engine, it will increase each gear’s RPM.
