The switch, marked 'N' is mounted on the right hand side of the casing and limits starter ENGAGEMENT to NEUTRAL/PARK positions and also activates the BACK-UP LIGHTS in REVERSE position. In case the engine starts and the shift lever is in any other position other than Park or Neutral, then the switch either needs to be adjusted or replaced. First, turn the shift lever to Neutral; next safely jack up the car and support it on jack stands. Turn the bolts on the neutral start switch counterclockwise to loosen it and further turn them clockwise to tighten and position the grove to the neutral basic line on the housing. Rotate the switch to have the groove in the end of the control shaft engage with the vertical index line in the switch before tightening the bolts. For proper adjustment, the continuity should be checked between the terminals that have been defined for switch electrical connector; if the switch fails the continuity test it means it has to be replaced.
