To start your engine with a booster battery, the instructions and precautions below must be followed. ● Whenever working on or near a battery, always wear suitable eye protectors (for example, goggles or industrial safety spectacles) and remove rings, metal bands, or any other jewelry. Do not lean over the battery when jump starting. ● Do not attempt to jump start a frozen battery. It could explode and cause serious injury. ● Your vehicle has an automatic engine cooling fan. It could come on at any time. Keep hands and other objects away from it. WARNING ● If done incorrectly, jump starting can lead to a battery explosion, resulting in severe injury or death. It could also damage your vehicle. ● Explosive hydrogen gas is always present in the vicinity of the battery. Keep all sparks and flames away from the battery. ● Do not allow battery fluid to come into contact with eyes, skin, clothing or painted surfaces. Battery fluid is a corrosive sulfuric acid solution which can cause severe burns. If the fluid should come into contact with anything, immediately flush the contacted area with water. ● Keep battery out of the reach of children. ● The booster battery must be rated at 12 volts. Use of an improperly rated battery can damage your vehicle. WARNING ● Always make sure that the spare tire and jacking equipment are properly secured after use. Such items can become dangerous projectiles in an accident or sudden stop. ● The spare tire is designed for emergency use. See specific instructions under the heading "Wheels and tires" in the "Maintenance and do-it-yourself" section of this manual. 6-8 In case of emergency
