1) Try turning the ignition switch to the “START” position with the headlights turned on to determine the battery condition.
If the headlights go excessively dim or go off, it usually means that either the battery has run down or battery terminal contact is poor. Recharge the battery or correct battery terminal contact if necessary.
2) If the headlights remain bright, check the fuses. If the reason for failure of the starter is not obvious, there may be a major electrical problem. Have the vehicle inspected by your authorized SUZUKI dealer.
