refer to section 10, Troubleshooting. When the condition is corrected,
the smart cable will automatically reset.
NOTE: Cold weather may affect the performance of the jump starter's
lithium battery. If you hear only a click and the engine does not turn
over, try the following:
With the jump starter connected to the car battery and the green LED
illuminated on the smart cable, turn on all lights and electrical accessories
for one minute. This draws current from the jump starter and warms the
battery. Now try to crank the engine. If it does not turn over, repeat the
procedure. Extremely cold weather may require two or three battery
warmings before the engine will start.
NOTE: If no activity is detected, the smart cable will automatically shut
off after 120 seconds, and the red and green LEDs will be solid. To reset,
disconnect the clamps from the vehicle battery, and then reconnect.
IMPORTANT: DO NOT attempt to jump start your vehicle more
than three consecutive times. If the vehicle will not start after three
attempts, consult a service technician.
8. After the engine starts, unplug the battery clamps from the jump starter
socket and then disconnect the black clamp (-) and the red clamp (+),
in that order.
