What is the function of D3 on the gear lever of the old CRV?

D3 refers to the low gear mode of the transmission. You can shift directly to D3 while driving without braking, but avoid doing so when the vehicle speed and engine RPM are high. Generally, automatic transmission vehicles have gear positions such as P, R, N, D, and S. Here are the specific details: 1. P (Park): When parking the car, the gear lever must be shifted into P position. 2. N (Neutral): N position is equivalent to neutral gear and can be used when starting, parking without leaving the vehicle, or during towing. 3. D (Drive): During normal driving, place the gear lever in D position, and the car will automatically shift between forward gears. D is the most commonly used gear. 4. S (Sport) mode: In S mode, the transmission can shift freely, but the shifting timing is delayed to keep the engine at high RPM for a longer time, allowing the car to maintain low gear and high RPM for extended periods, resulting in greater torque output and acceleration. While driving, simply push the gear lever into "S" position, which is typically used for climbing hills or rapid overtaking.
I remember when I drove the old CRV, the D3 button on the gear shift really came in handy, especially when cruising on mountain roads. Its main function is to keep the transmission shifting only between the first three gears, such as when going down steep slopes or towing something, preventing it from jumping to higher gears. This way, the engine can help with deceleration, reducing the need to brake frequently and protecting the brake pads from overheating. I often drive on mountain roads, and using D3 makes the car feel more stable, keeps the oil temperature from rising too high, and makes the drive much more comfortable. When I used to tow a small trailer for camping, D3 provided quicker power response and avoided excessive gear shifting. To be honest, knowing how to use these small features in an automatic transmission car makes driving safer and more convenient, and it also helps extend the lifespan of the components.
As an average car owner, I find the D3 design in the older CRV very thoughtful. It's essentially a gear limiter button - when activated, the vehicle only shifts among the first three gears without reaching fourth or higher. This proves particularly useful when climbing steep hills or descending long slopes, as engine braking helps control speed, significantly reducing brake burden. I use D3 less on highways, but in urban traffic congestion, it also minimizes gearshift jerks for smoother driving. Some worry about increased fuel consumption, but the actual impact is minimal. Maintenance remains straightforward - just remember to check transmission fluid regularly. In short, D3 is a practical little feature in older models, and mastering its flexible use can enhance daily driving experience.
