Don't lean over battery when attaching clamps or allow the clamps to touch each other. If acid splashes in eyes or on skin, flush contaminated area immediately with large quantities of water. A battery generates hydrogen gas which is flammable and explosive. Keep flame or spark away from the vent holes. Do not use a booster battery or any other booster source that has a greater than 12 volt system, i.e. Do not use a 24 volt power source. 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. JUMP STARTING If the vehicle has a discharged battery, booster cables may be used to obtain a start from a booster battery or the battery in another vehicle. This type of start can be dangerous if done improperly, so follow this procedure carefully.
