Mja pta krna h ya axio ma auto gear ma ya D ka sth plus or minus ka sign kis purpose ka lia h
Its called triptronic transmission. Having both manual and auto feature. When you shift into D its auto mode gears will change automatically..when you shift into S mode (+ and -) its into manual mode...you can shift the gears up(+) and down(-) just like a manual car. Its more like a sporty feature.Experts can explain better hope it helped.
'+' - next gear'-' - previous gear
There are speed requirements for each gear; the car will not allow you to shift into your chosen gear if you don't fall into that speed window, e.g. you won't be able to shift into 4th gear at 20 km/h.
