Emergency Starting With Jumper Cables
When using jumper cables, follow the instructions below.
Warning: Batteries release explosive gas. Do not smoke when working around batteries. Put out all flames and remove all sources of sparks or intense heat in the vicinity of the battery. Do not allow the vehicles to touch each other. Do not lean over the batteries when making connections, and keep all other persons away from the batteries. Failure to follow these precautions could lead to severe personal injury as a result of an explosion or acid burns.
Notice: Make sure both electrical systems are the same voltage. Electronic devices on both vehicles can be damaged when connected to a vehicle with a different operating voltage.
Note: On vehicles equipped with optional underhood jump start posts, connect to these posts instead of the batteries.
- Apply the parking brakes and turn off the lights and all other electrical devices.
- Remove the battery box cover.
- Connect the positive (+) jumper cable to the positive battery
post or jump start post on the vehicle needing the jump start. See Fig.,
ref. A.

- Then connect the other end of the positive jumper cable to the positive battery or jump start post of the vehicle providing the jump start.
- Connect one end of the negative jumper cable to the negative battery or jump start post of the vehicle providing the jump start.
- Then connect (ground) the other end of the cable to a negative battery or jump start post on the vehicle needing a jump start. See , ref. B.
- Start the engine of the vehicle providing the jump start and let the engine run a few minutes to charge the batteries of the other vehicle.
- Attempt to start the engine of the vehicle with the batteries receiving the charge. Do not operate the starter longer than 30 seconds, and wait at least two minutes between starting attempts to allow the starter to cool.
- When the engine starts, let it idle a few minutes.
- Disconnect the negative (grounded) jumper cable from the vehicle that needed the jump start. See , ref. B.
- Then disconnect the other end of the jumper cable from the vehicle that provided the jump start.
- Disconnect the positive jumper cable from the positive battery or jump start post of the vehicle that provided the jump start.
- Then disconnect the other end of the positive jumper cable from the positive battery or jump start post of the vehicle that received the jump start. See Fig., ref. A.
- Install the battery box cover; be sure it is positioned properly before fastening the latches.
Note: The battery box on an 108SD Plus and 114SD Plus may be located in a variety of locations, including under the passenger seat, behind the side fairing, or behind the cab. If the battery box is located behind the side fairing, it can be accessed by opening the side fairing kick panel.
Warning: Do the next step exactly as instructed and do not allow the clamps of one cable to touch the clamps of the other cable. Otherwise, a spark could occur near a battery, possibly resulting in severe personal injury from explosion or acid burns.
