![]() ![]() You can change from Drive to D3 while driving. Set the gear shifter to D3 when you are ready to limit how high the transmission goes. The vehicle will take off using the lowest gear available. If you are ready to try D3 in your automatic car, here are a few steps to follow. Usually, this is plenty of speed for regular driving, giving you more control when you have a lot of weight with you. With D3 gear, speed is limited to what’s available in the third range. However, you don’t want to ride the brakes, because this causes them to overheat and fade. It’s important to watch the vehicle speed when you haul cargo or tow a trailer. For this reason, the RPMs rise faster, allowing for quicker acceleration. When you put the vehicle in D3, it can’t shift into the higher gears. ![]() You might push down on the gas pedal, but the car barely feels like it’s gaining momentum. If the transmission shifts too soon, it’s hard to gain the acceleration needed to pull out into heavy traffic. By locking it in place, the wheels continue to get the traction needed to get out of bad conditions. With the transmission unable to shift higher than third gear, you have less of a chance of being stuck in bad weather conditions. However, D3 helps your vehicle retain control by preventing slipping between gears. It’s easy to lose traction when traveling on slippery roads. If you get the car up to speed and the RPMs remain too high, it will be best to shift back into overdrive. Because D3 keeps the transmission from shifting into overdrive, you see higher RPMs that translate into speed.Īs with all driving situations, you don’t want to overwork the transmission. Driving Uphillĭ3 might also be beneficial if you need to gain speed while driving uphill. However, running at high RPMs for too long can also cause wear to the engine. By utilizing this lower gear, the engine will keep the speed in check. They regularly apply engine braking to slow the vehicle down, and you can do the same with the D3 gear.ĭ3 reduces the pressure on the braking system, ensuring the pads don’t overheat. Truck drivers know how to handle a steep hill. The engine automatically keeps the vehicle reined in to ensure excessive speeds don’t become a problem. Because D3 allows you to run at lower gears, the car wheels won’t spin too fast, allowing you to gain more traction.Īdditionally, the engine brake function that was previously discussed helps you to remain safer when traveling down steep inclines. You might notice it more when driving in rainy weather, where the vehicle is prone to slipping. With D3 mode engaged, you gain more control over the vehicle. In this case, you might want to consider moving back to Drive to extend the longevity of the motor. However, if you are running the RPMs at the red line, this could be damaging to the car. D3 is also beneficial when traveling in the city because you don’t need higher speeds, but rely more on quick throttle response. If you are pulling out into heavy traffic, using lower gears can help you get the RPMs up higher for quicker acceleration. If you are traveling down a steep road, consider putting the transmission in D3 and letting the engine do some of the work. While it isn’t costly to replace most brake pads, there’s no reason to unnecessarily wear them out. Because of this setup, you don’t need to use the brake pedal as often, especially when going downhill. When the car is in D3, the engine reduces speed on its own. RELATED: What Does The S Mean On A Gear Shift? D3 Gear Driving Advantages 1. Its purpose is to save fuel and provide more efficiency during normal driving situations. The D (Drive) gear is considered overdrive. As an illustration, the D3 gear is limited to third gear, but it will also utilize first and second. These show you the maximum gear position that the car will go in while moving forward. You may see the D2, D3, and D4 selections. However, some vehicles offer other options below the D gear. When the car is in Drive, the gears shift automatically with the help of hydraulics. Typical driving requires the shifter to be set in D, and there’s nothing else to think about. Most automatic cars come with the standard set of gears, such as P (Park), R (Reverse) and D (Drive). D3 is used to provide more power in certain driving situations, and it also provides a broader RPM range for each gear. D3 uses the first three gears of the vehicle’s automatic transmission, locking it into third gear as the highest option. How to Use D3 Gear in an Automatic Car What Does D3 Mean in a Car?ĭ3 is a mode that is useful when driving down or up steep hills. ![]()
