Jump Starting: Service and Repair
Jump Starting in Case of Emergency (Non HP2)
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.
This vehicle has a 12-volt positive, negative ground electrical system. Do not try to jump start a vehicle, if you are unsure of the other vehicle's positive
voltage or ground position. The booster battery and the discharged battery should be treated carefully when using jumper cables.
1. Position the vehicle with the booster battery so that the jumper cables will comfortably reach the battery of the other vehicle.
*
Do not let the 2 vehicles touch.
*
Make sure that the jumper cables do not have loose clamps or missing insulation.

5. Attach one end of the remaining jumper cable to the negative terminal of the booster battery.
Notice: Do not connect the negative charger lead to the housings of other vehicle electrical accessories or equipment. The action of the battery
charger may damage such equipment.
6. Make the final connection of the negative jumper cable to the block or suitable bracket connected directly to the block, away from the battery.
