    Question CVT and Break gear newbie question.

    Hi, recently bought a 2013 Mirage LS. Im a middle aged female who doesnt really know much about transmission.

    Could someone explain to me in laymans terms what this CVT thing is all about? My understanding is that the engine is constantly going smoothly from 1 to 10 and back, as opposed to the normal auto transmission that clearly goes from 1st to 2nd, to 3rd... etc.
    Am I close?

    Also, what is this breaking (B) option below the drive (D) gear?
    In the book it said its for when you need engine breaking, like in a traffic jam or something?
    Which situations would it be used in? Why? Is it fuel efficient? Can it be used on highways at 110kmph?

    So CVTs don't have gears per say. It's a metal belt ran between pulleys that tries to keep the engine at the correct power band while keeping revs low enough for great fuel economy. Our CVTs do have a 2 speed gear that increases how many different ratios the engine and transmission can have. Sometimes you might feel it kick down, so don't worry it's normal.

    B gear is for engine braking. It's not for high speed travel... use it to slow down down steep grades or whenever you want to use brakes less. Also for climbing steep grades at low speeds.

    Thanks.
    When you say our CVTs, do you mean the CVTs in every Mirage? Even in Australia?

    If Im stationary and then I take off up a slight hill, the car seems to be in a really low gear (I know thats the wrong word) for a few seconds, and it feels like when youre in a manual going up a hill and youre in 4th instead of 3rd, together with that really low-pitched grumble from the engine.
    Is that normal?
    And should it happen for that long? Its about 2 seconds, which doesnt sound long, but yesterday it nearly got me hit by another car as I was turning onto a main road from a side road.

    Can anyone give me lots of other examples where you might use the B gear?
    I’m a bit of a slow learner, and need plenty of examples to get it gelled in my head.

    Using "B" will keep your CVT in the lower range of gearing. Try experimenting with it such as taking off from a stop and apply a healthy amount of throttle then manually upshifting into "D". I use it all the time to accelerate from a stop on a hill and upshift into "D' at approximately 70 Kph. I've downshifted into "B" at speeds as high as 100 Kph to assist slowing down on steeper hills.
