Engine Won't Start Due to ABS Light, How to Unlock the Gear Lever

Model: Smart Smart 451 - Years 2007-2015
Part: Warning light – error code

The illumination of the ABS light prevents the engine from starting. The fault is likely not related to the ABS device but to a faulty microswitch. To start the vehicle, you will need a long screwdriver and a sturdy support about a few centimetres high. Place the gear lever in the BRAKE position, position the support near the passenger side tunnel, then insert the screwdriver between the tunnel and the plastic cover of the gearbox, resting the tip of the screwdriver on the support. Using the support as a pivot, lever the screwdriver upwards until you hear the click of the switch located under the cover. Move the gear lever to the park position and start the engine.
