Make sure the vehicles do not touch each other. Set the parking brake on both vehicles and stay clear of the engine cooling fan and other moving parts. Check all battery terminals and remove any excessive corrosion before you attach the jumper cables. Turn on the heater fan in both vehicles. If you have electronic climate control, press the V F-DEF button. Turn off all other switches and lights. 3. 4. 5. Connecting the jumper cables 1. Connect one end of the first jumper cable to the positive (+) terminal of the discharged battery. (You can connect either jumper cable to the positive (+) terminal, as long as you use the same cable for both positive terminals.) Most jumper cables have a red cable and a black cable. The red cable is generally used for the positive terminals and the black for the negative ones. Connect the other end of the first cable to the positive (+) terminal of the booster battery. Connect one end of the second cable to the negative ( ) terminal of the booster battery - NOT to the discharged battery. Connect the other end of the second cable to a good metallic surface on the engine or frame of the disabled vehicle. 219 2. 3. 4.
