Smart - Video tutorial

Model: Smart Smart 451 - Years 2007-2015
Part: Gearbox
Operation: How to reset the gearbox of the Smart 451?

When the flashing letter N appears on the instrument panel display of the Smart 451, it means that the gear change is faulty. To be able to resolve this anomaly temporarily, it is possible to engage gear with the engine off. Subsequently, with the gear engaged and with the ignition key in position two, the car must be pushed so that it can start. Once the clutch is released during the push operation, the car will start. However, you must go to the workshop promptly to solve the problem and avoid worse damage.

Handbrake adjustment on Ford Ecosport

First remove the plastic profile at the base of the gear lever. To do this, slightly widen the side edges and carefully lift it to release it. There is no need to remove it completely, just move it forward to avoid bother. Now remove the plastic center console around the handbrake by first working from the rear to release it and lifting it until the brake lever passes. Also in this case it is not necessary to remove it completely but, paying attention to the connected cables, it can be stowed in front of the passenger seat. At this point we notice that at the base of the handbrake lever, on the front, we find a nut. By acting on it, with a 10 wrench, we can adjust the brake force, increasing it by turning the nut clockwise, or decreasing it by turning it counterclockwise. Once adjusted, the center console can be repositioned first, pressing lightly to engage it, and then the profile of the gearbox base.
