Precautions

CAUTION
  • Ensure the positive (+) terminals of both batteries are connected. Do not connect the negative (-) terminal of the rescue vehicle's battery to the negative terminal of the broken-down vehicle's battery. Instead, connect it to the broken-down vehicle's grounding point. Otherwise, sparks generated during connection may ignite flammable gases from the battery, causing an explosion.
  • Use a 12V battery for the rescue. If the rescue vehicle's battery voltage is higher than 12V, it may damage the vehicle's electrical equipment.
  • When connecting or disconnecting jumper cables, fully connect or disconnect one cable before connecting or disconnecting the other to avoid short circuits.
  • Ensure the clamps of the jumping cables do not touch any other metal.
WARNING
  • If the positive and negative terminals of the battery are connected incorrectly during jump-starting, it can cause vehicle damage (such as blown fuses/relays) and may even lead to a battery explosion.
  • Incorrect jump-starting can cause a battery to explode. A battery explosion can cause serious injury or death and can also damage the vehicle. Be sure to follow the instructions in this section.
  • There is always explosive hydrogen gas near the battery. The battery must be kept away from sparks and fire.
  • When working on or near the battery, wear appropriate eye protection and remove rings, bracelets, and other jewelry.
  • Do not lean over the battery during jump-starting to avoid being burned by acid.
WARNING
  • Do not allow battery acid to come into contact with eyes, skin, clothing, or the paint surface of the vehicle. Battery solution is a corrosive sulfuric acid solution, which can cause serious burns. If acid comes into contact with any part, immediately rinse the surface with plenty of water.
  • Keep the battery out of reach of children.
  • Do not attempt to jump start a frozen battery. It may explode and cause serious accidents.
