If the Engine Won't Start When the IMA battery charge is low, the starter motor is used to start the engine. If the engine does not start, check the following: Turn the ignition switch to the ON (II) position. Turn on the headlights, and check their brightness. If the headlights are very dim or do not come on at all, the battery is discharged. See Jump Starting on page 396 . Turn the ignition switch to the START (III) position. If the headlights do not dim, check the condition of the fuses. If the fuses are OK, there is probably something wrong with the electrical circuit for the ignition switch or starter motor. You will need a qualified technician to determine the problem. See Emergency Towing on page 412 . If the headlights dim noticeably or go out when you try to start the engine, either the 12 volt battery is discharged or the connections are corroded. Check the condition of the 12 volt battery and terminal connections (see page 381 ). You can then try jump starting the vehicle from a booster 12 volt battery (see page 396 ). If you find nothing wrong, you will need a qualified technician to find the problem. See Emergency Towing on page 412 . Taking Care of the Unexpected 395 2010 Insight
