336 WHAT TO DO IN EMERGENCIES NOTE: Tire should be stowed with the "beauty" side up. Storing the tire upside down may result in scratching or damage to the wheel face. Continue winching up the tire until you hear the winch "ratchet" three times. Double check to ensure the tire is snug against the underbody of the vehicle. Damage to the winch cable may result if the vehicle is driven with the tire loose. JUMP STARTING PROCEDURE NOTE: Check the charge indicator on the battery. If the indicator is light or yellow, replace the battery. 1. Wear eye protection and remove any metal jewelry such as watch bands or bracelets that might make an unintended electrical contact. 2. When boost is provided by a battery in another vehicle, park that vehicle within booster cable reach but without letting the vehicles touch. Set the parking brake, place the transmission in P (Park), and turn the ignition to OFF for both vehicles. 3. Turn off the heater, radio and all unnecessary electrical loads. 4. Connect one end of a jumper cable to the positive terminal of the discharged battery. Connect the other end of the same cable to the positive terminal of the booster battery. WARNING! Do not use power tools to winch the tire up or down. Impact type tools may damage the winch mechanism. 12. Reinstall the plastic plug into the floor of the cargo area.
