  1. Raise hood on disabled vehicle and visually inspect engine compartment for:
    • Generator drive belt condition and tension.
    • Fuel fumes or leakage, correct if necessary.
    • Frozen battery.
    • Yellow or bright color test indicator, if equipped.
    • Low battery fluid level.
    CAUTION: If the cause of starting problem on disabled vehicle is severe, damage to booster vehicle charging system can result.
  2. When using another vehicle as a booster source, turn off all accessories, place gear selector in park or neutral, set park brake or equivalent and operate engine at 1200 rpm.
  3. On disabled vehicle, place gear selector in park or neutral and set park brake or equivalent. Turn OFF all accessories.
  4. Connect jumper cables to booster battery. RED clamp to positive terminal (+). BLACK clamp to negative terminal (-). DO NOT allow clamps at opposite end of cables to touch, electrical arc will result. Review all warnings in this procedure.
  5. On disabled vehicle, connect RED jumper cable clamp to battery positive (+) terminal. Connect BLACK jumper cable clamp to the engine as close to the ground cable connection as possible.
    CAUTION: Do not crank starter motor on disabled vehicle for more than 15 seconds, starter will overheat and could fail.
  6. Allow battery in disabled vehicle to charge to at least 12.4 volts (75% charge) before attempting to start engine. If engine does not start within 15 seconds, stop cranking engine and allow starter to cool (15 min.), before cranking again.
