Jump Starting If your car's battery has run down, you may be able to start the engine by using a booster battery. Although this seems like a simple procedure, you should take several precautions. To jump start your car, follow these directions closely: A battery can explode if you do not follow the correct procedure, seriously injuring anyone nearby. Keep all sparks, open flames, and smoking materials away from the battery. You cannot start a Honda with an automatic transmission by pushing or pulling it. 1. Open the hood and check the physical condition of the battery (see page 294 ). In very cold weather, check the condition of the electrolyte. If it seems slushy or like ice, do not try jump starting until it thaws. If a battery sits in extreme cold, the electrolyte inside can f reeze. Attempting to jump start with a f rozen battery can cause it to rupture. 2. Turn off all the electrical accessories: climate control, stereo system, lights, etc. Put the transmission in Neutral or Park, and set the parking brake. 342 Taking Care of the Unexpected
