Line 19:

* '''L/1 and 2 gears in a full automatic''': The MMT does not provide L/1 and 2 gears as in a full automatic. One action of the MMT system is that it detects the gradient of the slope that the car is situated in. On a down-sloping incline and if the brake pedal is depressed, it automatically selects a lower gear to produce engine brake, which has the equivalent effect of L and 2 gears in a full automatic. L and 2 can also be substituted with E1 and E2 (not available in [[Aygo]]) or M1 and M2 gears in a MMT car. To select E1 or E2, put the gear to E, and use + and - pedal flaps on the steering wheel to override the computer selection. E will change to E1/E2/E3/E4/E5/E6, depending on the gear selected. Downshift to E1 or E2 as appropriate to simulate L and 2 gears in a full automatic. To select M1 or M2, put the gear to M, and use M- gear to downshift the gear to M1 or M2.

* '''Kick-down''': In E mode, the [[Automatic transmission#Manually controlled automatic transmissions|kick-down function]] in a full automatic can be similarly activated in an MMT car. Additionally, the kick-down function can be manually activated using the - pedal flap on the [[steering wheel]] in E mode. This overrides the computer setting and E changes to E1/E2/E3/E4/E5/E6. To stop the [[manual override]] under E mode, pull and hold the + flap on the steering wheel, until the E1/E2/E3/E4/E5/E6 changes back to E. Alternatively, wait for the next computer activated gear change.

* '''Reverse''': The car reverses as in an automatic car. To reverse, depress brake pedal, and change the gear to R. Gradually lift off the brake pedal to allow the car to creep backwards. On a down-sloping incline, the creep function, simulated using the slipping clutch, is not sufficient to prevent the car from rolling forward. In this case, the car must not be held still using the accelerator pedal, as the excessive clutch slipping will lead to clutch damage. Handbrake should be instead applied, and the accelerator pedal should be depressdepressed slightly.

* '''Gear change''': The gear change in MMT is noticeable, unlike in a full automatic car. Under E gear, the car will automatically change the gear depending on speed and [[gradient]] information. It is recommended that the accelerator pedal should be momentarily lifted off during gear change. A constant throttle can also be maintained on the accelerator, and gear change can still occur, although the car will feel noticeably more jerky during gear change than in a full automatic.
