Jump Starting If your vehicle's battery (or batteries) has run down, you may want to use another vehicle and some jumper cables to start your vehicle. Be sure to use the following steps to do it safely. Notice: Ignoring these steps could result in costly damage to your vehicle that would not be covered by your warranty. Trying to start your vehicle by pushing or pulling it will not work, and it could damage your vehicle. 1. Check the other vehicle. It must have a 12-volt battery with a negative ground system. Notice: If the other vehicle's system is not a 12-volt system with a negative ground, both vehicles can be damaged. Only use vehicles with 12-volt systems with negative grounds to jump start your vehicle. 2. If you have a vehicle with a diesel engine with two batteries (or more), you should know before you begin that, especially in cold weather, you may not be able to get enough power from a single battery in another vehicle to start your diesel engine. If your vehicle has more than one battery, use the battery that is closer to the starter - this will reduce electrical resistance. {CAUTION: Batteries can hurt you. They can be dangerous because: • They contain acid that can burn you. • They contain gas that can explode or ignite. • They contain enough electricity to burn you. If you do not follow these steps exactly, some or all of these things can hurt you. 518
