Charging a Weak Battery:
Be sure the Auto Jumper is not connected to the vehicle before attempting to start vehicle.
Turn off lights and all other electrical accessories (eg. Fan, radio, windshield wipers, etc.) Turn on the small

Push the "On/Off" button to the "On" Position.
The light on the 12-volt cigarette connector will illuminate to show charging has begun. The interior light will
also illuminate.
If the light or dial does not brighten, Turn on the ignition key to the "Accessories" position (see vehicle
owner's manual). If your vehicle's 12-volt cigarette lighter or power source is off when the ignition is off, be
sure the ignition key is set to the "Accessories" position during the recharging process.
If the interior light does not brighten, turn off the interior light. Allow the unit to remain in the cigarette lighter
for at least 35 minutes.
Attempt to start the vehicle. If the vehicle does not start, DO NOT attempt to start the engine more than
twice. Call a service center or tow truck.
