What do the + and - signs on the gear shift mean?

[KevinMarie]

The plus and minus signs on the gear shift indicate the manual mode's gear shifting function, allowing you to manually adjust the gear up or down. Scenarios for using manual gear shifting: The plus sign can be used when climbing hills. The D gear, also known as the drive gear, automatically engages the appropriate forward gear based on throttle position and vehicle speed when the gear shift lever is in this position. Advantages of manual gear shifting: Manual/automatic transmission. This allows high-performance sports cars to break free from the constraints of traditional automatic transmissions, giving drivers the joy of manual shifting. These vehicles feature '+' and '-' gear selection options. When in D gear, drivers can freely downshift (-) or upshift (+), similar to a manual transmission. Drivers can force downshifts to slow down before entering a curve, just like with a manual transmission, and then accelerate out of the curve in a lower or middle gear.
