What Does the L on a Gear Shift Mean
Driving a car with an automated manual has several benefits over the manual gearbox, mainly in terms of convenience. Stick shift does allow the commuter to modify gears when they see fit, but modern automatics have more than gears and provide a smoother and fifty-fifty more than fuel-efficient ride.
Most automatic owners know how to operate the gear lever – Park, Reverse, Neutral and Drive. Even so, "3", "2" and "50" positions are almost never used, to the extent that drivers forget what they're for.
The "L" on gear shift stands for Low, a depression gear mode that prevents the transmission from shifting up across the commencement or second gear. Not to be confused with depression range, "L" gear mode has several useful applications. In this guide, we'll explore how low gear mode works and what information technology can be used for.
Understanding Engine Braking
To better understand the purpose of the low gear mode, nosotros need to learn what engine braking is.
When you're driving downhill, if yous set your car into neutral, it will deed as a sleigh and accelerate uncontrollably. You can counter this by applying brakes, but they can quickly overheat and lose all braking power. You lot should never drive downhill while in neutral!
Engine braking occurs when yous release the throttle, merely the vehicle continues to accelerate. As the throttle valve is closed almost completely, a potent vacuum is created that saps a lot of the potential energy and creates the engine-braking upshot.
In other words, when you press the gas pedal, the engine raises RPM and this rotational speed is transferred to the gearbox, and onto the wheels. When you're driving downhill, the wheels want to spin faster than the engine, which is prevented past engine braking. By placing a manual gear level in 2nd gear, nearly cars will maintain a descending speed of 30mph, with no input on the restriction pedal.
What happens when the "D" or drive style is selected depends on the applied science within the vehicle. Modernistic cars have intelligent systems that know when the vehicle is going downhill and appoint hill descent to assist to help the commuter retain command. Older automated transmission will go on to upshift as you continue to accelerate, which ways the engine volition never get to assistance you lot with braking.
To force an automated to brake with the engine, you demand to drive in a lower gear and prevent the transmission from shifting upward while yous're descending. This is washed by using the gear lever settings below Drive – "3", "2", and "L".
Is Engine Braking Rubber?
One of the well-nigh dangerous misconceptions in the automotive globe is thinking that engine braking will damage the engine. Engine braking will not cause any damage to the engine, and even if it did, information technology's far improve to damage the engine, than to burn down out brakes your brakes and advance uncontrollably.
But I'll say it one more time to clarify: engine braking volition non harm your engine. Your primary mode of decision-making the automobile on a descent should be through engine braking, with brakes applied before sharp corners. I cannot tell you how many times I've driven downhill and smelt called-for brakes coming from other cars, while I hadn't touched my brake pedal at all.
Information technology may be scary the first fourth dimension yous effort engine braking, every bit the engine will rev up high and make a lot of racket. This is completely normal and nix to worry almost – the engine is consuming a very depression amount of fuel, and despite the loftier RPM, it's really preventing the vehicle from accelerating.
What Does "L" Gear Style Do?
Almost every automatic transmission has the "L" gear way, with some including either "3" or "2", or fifty-fifty both. The "3" setting volition prevent the transmission from shifting beyond the tertiary gear, with "2" restricting it to only the offset and second gear.
These are your standard hill descent modes, and you should use one or the other whenever y'all're going downhill. If you're driving a low-power automatic, keeping your automobile in "three" will also prevent information technology from shifting upwards when going uphill, which will continue the RPM high and provide maximum power for a safe ascent.
The "L" mode limits the number of gears you tin can use even further – only the first, and in some transmissions, the second gear volition remain active. This will brand the vehicle necessarily ho-hum, with "3" beingness more than enough to go on the vehicle in control.
All the same, when you're hauling or towing heavy loads, "L" can be a lifesaver. The added weight of the cargo not but speeds up the vehicle but also makes it much harder to decelerate when driving downhill. By setting the gear in "Fifty", the speed of the vehicle will exist limited through engine braking, resulting in a safe descent.
When Should I Use "L" Gear Mode?
Whenever y'all're facing an incredibly steep incline or descent, lower gears volition provide improve control over the vehicle while retaining low speed.
If a steep incline on a dirt road is ahead of you lot, stepping on the gas while in "D" will make you accelerate across the point considered prophylactic on such a surface. Place the transmission in "L", enhance the RPM to an optimal level, and you'll achieve the top more than easily.
It is crucial that you utilise the "50" gear fashion when descending with a heavy load, similar a camping ground trailer or towed car. If you've always seen 18-wheelers crawl painfully slow downward the hill, it's considering they're doing the same thing.
That being said, "L" is still reserved for the most extreme scenarios. The first position below "D", whether it's "three" or "ii" will be sufficient for most situations.
PRNDL Meaning
I've been asked this question several times in this exact manner (and not all of them were the Zack and Cody joke), and so information technology felt appropriate to include a section dedicated to this question. While most people understand what each position does, many are not certain what each of the letters stands for.
"P" = Park, the position designed for parking the vehicle, as it engages the first or contrary gear and prevents the vehicle from moving.
"R" = Reverse, the gear for driving in reverse with limited speed.
"Northward" = Neutral, the position where transmission isn't engaged and the vehicle tin can be pushed freely.
"D" = Drive,the position responsible for all forwards-driving gears.
"50" = Low,the low gear setting that prevents the transmission from automatically shifting upwardly across the 2nd or the third gear.
FAQs
When should you drive in low gear?
As mentioned before, the "50" or low gear is a bully way to control the vehicle when driving on colina roads. Modern cars do not take the "3" or "ii", making the depression gear the universal option, with colina descent control designed to assist when hauling heavy loads.
Tin can you shift from D to Fifty while driving?
The switch betwixt drive and low gear can exist done on the fly, but a good practise is to lower your speed before engaging in the low gear mode. Your transmission likely has a condom organisation that will preclude it from downshifting when the vehicle is moving also rapidly, which also means that depression gears won't be engaged immediately. Learn how your vehicle drives and shifts, lower your speed so engage the "L" gear mode.
Is it bad to drive on Fifty?
Driving in low gear isn't necessarily bad, but limits your ability to reach higher speeds, and driving whatever faster than those gears tin accept will increase your fuel consumption. The best exercise is to go on the manual in "D" and apply "L" when necessary.
Summary
Now that you're familiarised with the meaning of the "L" low gear mode, y'all can take advantage of it to improve control during hill climbs and especially descents. We hope yous've learned something past reading this commodity, and we've got a lot of useful guides for you lot to read and learn all about cars!
