and run the engine for a while.
11. Try to start the vehicle that had the dead
battery. If it will not start after a few tries,

Notice: If the jumper cables are connected or
removed in the wrong order, electrical
shorting may occur and damage the vehicle.
The repairs would not be covered by your
warranty. Always connect and remove
the jumper cables in the correct order, making
sure that the cables do not touch each other
or other metal.
