WHAT TO DO IN EMERGENCIES 403 2. When boosting from a battery in another vehicle, park that vehicle within booster cable reach, but without allowing the vehicles to touch. 6. Connect the other cable, first to the negative terminal of the booster battery and then to the engine ground of the vehicle with the discharged battery. Make sure you have a good contact on the engine ground. WARNING! Do not permit vehicles to touch each other as this could establish a ground connection and personal injury could result. 3. Set the parking brake, place the automatic transmission in PARK (or NEUTRAL for manual transmission), and turn the ignition OFF for both vehicles. 4. Turn off the heater, radio and all unnecessary electrical loads. 5. Connect one end of the jumper cable to the positive battery post. Connect the other end of the same cable to the positive terminal of the booster battery. WARNING! • You should not try to start your vehicle by pushing or towing. • Do not connect the cable to the negative post of the discharge battery. The resulting electrical spark could cause the battery to explode. • During cold weather when temperatures are below the freezing point, electrolyte in a discharged battery may freeze. Do not attempt jump-starting because the battery could rupture or explode. The battery temperature must be brought up above the freezing point before attempting jump-start. 6
