Caution: Batteries produce explosive gases. Batteries contain corrosive acid. Batteries supply levels of electrical current high enough to cause burns. Therefore, in order to reduce the risk of personal injury while working near a battery, observe the following guidelines:

   • Always shield your eyes.
   • Avoid leaning over the battery whenever possible.
   • Do not expose the battery to open flames or sparks.
   • Do not allow battery acid to contact the eyes or the skin.
      - Flush any contacted areas with water immediately and thoroughly.
      - Get medical help.

Notice: This vehicle has a 12 volt, negative ground electrical system. Make sure the vehicle or equipment being used to jump start the engine is also 12 volt, negative ground. Use of any other type of system will damage the vehicle's electrical components.

  1. Position the vehicle with the booster battery so that the jumper cables will reach.
  2. • Do not let the two vehicles touch.
    • Make sure that the jumper cables do not have loose ends or missing insulation.
  3. Place the automatic transmission in PARK. If equipped with a manual transmission, place in NEUTRAL and apply the parking brake.
  4. Turn OFF all electrical loads on both vehicles that are not needed. Leave the hazard flashers ON, if required.

    Notice: Never operate the starter motor more than 15 seconds at a time without pausing in order to allow it to cool for at least 2 minutes. Overheating will damage the starter motor.

  14. Attempt to crank the engine of the vehicle with the discharged battery. If the engine does not crank or cranks too slowly, perform the following:
  15. • Ignition OFF.
    • Allow the booster vehicle engine to run at approximately 1,500 RPM for an additional 5 minutes.
    • Attempt to start the engine of the vehicle with the discharged battery.
  16. After the engine of the vehicle with the discharged battery starts, remove the jumper cables as follows.
  17. • The black negative (-) cable must be first disconnected from the vehicle that was boosted.
    • Disconnect the black negative (-) cable from the negative remote post of the booster  battery.

       Notice: Do not let the cable end touch any metal. Damage to the battery and other components may result.
