What is the '+' and '-' gear in the X-Trail?

[OAnderson]

The '+' and '-' gear in the X-Trail refers to the manual mode of an automatic transmission. It is a type of automatic transmission that adds the function of manual gear shifting on top of the automatic mode, with no fundamental difference between the two. '+' means to upshift, while '-' means to downshift. Relevant details are as follows: 1. To engage the manual mode of the automatic transmission, press the brake and shift the gear lever down to 'D' position, then push the lever to the left until 'S' lights up, indicating manual mode is engaged. To shift gears, push the lever forward '+' to upshift or pull it backward '-' to downshift. 2. Note that the transmission control unit will not allow upshifting if the vehicle speed or engine RPM is insufficient. In manual mode, the transmission will downshift for you at low speeds but will not upshift automatically. To return to automatic mode, simply push the lever back to the right. You can switch between manual and automatic modes at any time without braking or releasing the accelerator.
