What does the 123 gear in Teana mean?
2 Answers
Teana's 123 gears, D1, D2, D3 in automatic transmission, correspond to these three gears. D1: It manually locks the car's gear in first gear, not controlled by the car itself. D2: It manually locks the gear in second gear, not exceeding second gear, allowing the car to automatically switch between first and second gears. D1 and D2 can be used when going uphill; on steep slopes, manually setting the gear to first or second is similar to using manual transmission on a steep slope. D3: It locks the gear in third gear, allowing the car to automatically switch among first, second, and third gears, but not exceeding third gear. The advantage of D3 is faster response when overtaking.
I've been driving a Nissan Teana to commute, and its 1-2-3 gears are not separate gears but rather a manual mode that can be activated under the D (Drive) position of the automatic transmission, allowing you to limit the highest gear. For example, 1st gear is suitable for climbing steep slopes or starting on snowy roads, keeping the engine at low speed with high torque for more stable starts; 2nd gear is used for slippery roads or moderate uphill climbs to prevent wheel spin; while 3rd gear is ideal for long descents or mountain roads, using engine braking to help control speed and reduce reliance on the brakes. In daily city driving, I usually keep it in D mode and only switch to manual mode for special road conditions—this makes driving more effortless and extends brake life. These features are designed into automatic transmissions to enhance safety and adapt to different terrains, so there's no need to worry about overheating or slipping issues.
