Do not try to jump start a vehicle i f you are unsure of the other vehicle’s voltage or ground, or if the other vehicle’s voltage and ground are different.
Diesel engine vehicles have more than one battery. Should the vehicle have an optional diesel engine or an auxiliary battery option, use only the battery on the passenger side of the vehicle.
This procedure can be used to start a single-battery vehicle from any of the diesel engine vehicle’s batteries. However, at low temperatures, it may not be possible to start a diesel engine vehicle from a single battery in another vehicle.
The booster battery and discharged battery should be treated carefully when using jumper cables. Follow the procedure outlined below, being careful not to cause sparks.
CAUTION: Batteries produce explosive passes, contain corrosive acid, and supply levels of electrical current high enough to cause burns. Therefore, to reduce the risk of personal injury when working near a battery:
• Always shield your eyes and avoid leaning over the battery whenever possible.
• Do not expose the battery to open flames or sparks.
• Do not allow battery acid to contact the eyes or skin. Flush any contacted areas with water immediately and thoroughly, and get medical help.
• Follow each step in the jump starting instructions.
NOTICE: Do not push or tow the vehicle to start it. Under some conditions this may damage the catalytic converter or other parts of the vehicle. Also, since this vehicle has a 12-volt negative ground electrical system, make sure the vehicle or equipment used to jump start the engine has a 12-volt negative ground electrical system. Use of any other type system may damage the vehicle’s electrical components .
JUMP STARTING PROCEDURE
1. Position the vehicle with the good (charged) battery so that the jumper cables will reach, but NEVER let the vehicles touch. Also, make sure the jumper cables do not have loose or m i ssing insulation.
2. Set the parking brake and place the transmission in neutral. Block the wheels. Turn off the ignition switch, lights, and all other electrical loads that aren’t needed except for the hazard flasher or any lamps needed for the work area.
3. Check the built-in hydrometer. If it is clear or light yellow, do not attempt to jump start the battery. Replace it.
4. Attach the end of one jumper cable to the positive terminal of the booster battery and the other end of the same cable to the positive terminal of the discharged battery (figure 9). A is the charged battery, B is the dead battery.
5. Attach one end of the remaining negative jumper cable to the negative terminal of the booster battery.
6. Make the final connection of the negative cable to a solid ground (such as an A/C compressor bracket), at least 450 mm (18 inches) from the battery of the vehicle being started (figure 9).
7. Start the engine of the vehicle that is providing the jump start and turn off all electrical accessories. Then start the engine in the vehicle with the discharged battery.
8. Reverse steps 4, 5, and 6 exactly when removing the jumper cables. The negative cable must be disconnected from the engine that was jump started first (figure 10).
