What does the D3 gear in CRV mean?
2 Answers
crv's D3 gear is a low-speed gear mode. After engaging the D3 gear, the car's gear is limited to shifting between gears 1 to 3 and will not automatically upshift. It is generally used when the vehicle speed is below 40 kilometers per hour. The D3 gear is typically used when descending steep slopes, allowing the car to use engine power for braking, preventing the driver from having to press the brake for extended periods, which could overheat the brake pads and pose a danger. The D3 gear is also a driving gear, similar to the D gear except that it only shifts between the first three forward gears. However, drivers must pay attention to the maximum speed allowed by the third gear to avoid damaging the engine.
I've been driving a CRV for several years, and the D3 gear in an automatic transmission is a very practical setting, mainly used to limit the transmission to work only in lower gears, typically from 1st to 3rd. For example, when driving up mountain roads or carrying a full load uphill, switching to D3 prevents the car from unnecessarily shifting to higher gears, providing more power and making the climb much easier. On steep downhill slopes, it also helps with automatic deceleration by using engine braking, which is safer and smoother than manually applying the brakes. In city traffic or when turning, using D3 reduces frequent gear shifts, making the driving experience more stable. Additionally, for SUVs like the CRV with higher ground clearance, using D3 on slippery roads during rain or snow improves wheel traction and reduces the chance of skidding. However, for normal highway or flat road driving, using the standard D gear is more fuel-efficient and comfortable.
