Most vehicles will immediately start. Some vehicles
may require the jump starter to be connected for up
to 30 seconds before starting. If the vehicle does not
start right away, wait 20-30 seconds and try again. Do
not attempt more than five (5) consecutive jump starts
within a fifteen (15) minute period. Allow the jump
starter to rest for fifteen (15) minutes before attempting
to jump start the vehicle again.
