The gases around the battery can explode if exposed to flames, sparks, or lit cigarettes. An explosion could result in personal injury or vehicle damage.|
Batteries contain sulfuric acid which can burn skin, eyes and clothing, if contacted.
Use only an adequate-sized cable with insulated clamps.
Preparing Your Vehicle
Do not attempt to push-start your automatic transmission vehicle. Automatic transmissions do not have push-start capability. Attempting to push-start a vehicle with an automatic transmission may cause transmission damage.
Use only a 12-volt supply to start your vehicle.
Do not disconnect the battery of the disabled vehicle as this could damage the vehicle's electrical system.
Park the booster vehicle close to the hood of the disabled vehicle, making sure the two vehicles do not touch. Turn all accessories off.
Connecting the Jumper Cables
Do not attach the cables to fuel lines, engine rocker covers, the intake manifold or electrical components as grounding points. Stay clear of moving parts. To avoid reverse polarity connections, make sure that you correctly identify the positive (+) and negative (-) terminals on both the disabled and booster vehicles before connecting the cables. Battery positions may vary.|
In the illustration, the bottom vehicle represents the booster vehicle.
- Connect the positive (+) jumper cable to the positive (+) terminal of the discharged battery.
- Connect the other end of the positive (+) cable to the positive (+) terminal of the assisting battery.
- Connect the negative (-) cable to the negative (-) terminal of the assisting battery.
- Make the final connection of the negative (-) cable to an exposed metal part of the stalled vehicle's engine, or connect the negative (-) cable to the ground connection point, if available.
Do not connect the end of the second cable to the negative (-) terminal of the battery to be jumped. A spark may cause an explosion of the gases that surround the battery.|
- Start the engine of the booster vehicle and rev the engine moderately, or press the accelerator gently to keep your engine speed between 2000 and 3000 rpms, as shown in your tachometer.
- Start the engine of the disabled vehicle.
- After starting the disabled vehicle, run both vehicle engines for an additional three minutes before disconnecting the jumper cables.
Removing the Jumper Cables
Remove the jumper cables in the reverse order that they were connected.
- Remove the jumper cable from the ground metal surface or connecting point, if available.
- Remove the jumper cable on the negative (-) terminal of the booster vehicle's battery.
- Remove the jumper cable from the positive (+) terminal of the booster vehicle's battery.
- Remove the jumper cable from the positive (+) terminal of the disabled vehicle's battery.
After starting your disabled vehicle and removing the jumper cables, allow your vehicle to idle for several minutes so the battery can recharge.
