NOTICE: Ignoring these steps could result in costlydamage to your vehicle that wouldn't be coveredby your vehicle warranty. Trying to start your vehicle by pushing or pulling it could damage your vehicle, even if you have a manual transmission. And if you have an automatic transmission, it won't start that way. To Jump Start Your Vehicle Check the other vehicle. It must have a 12-volt battery with a negative ground system. NOTICE: If the other system isn'ta 12-volt system with a negative ground, both vehicles can be damaged. If you have a diesel engine vehiclewith two batteries(or more), you should know before you begin that, especiallyin 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's on the passenger sideof the vehicle - this will reduce electrical resistance. Get the vehicles close enoughso the jumper cables canreach, but be sure the vehicles aren't touching each other. If they are, it could cause a ground connection you don't want. You wouldn't be able to start your vehicle, and the bad grounding could damage the electrical systems. You could be injured if the vehicles roll. Set the parking brake firmly on each vehicle. Put an automatic transmission in PARK (P) or a manual transmission in NEUTRAL (N). If you have a four-wheel-drive vehicle, be sure the transfer case is not in NEUTRAL (N). 5-3
