6. Operating Instructions: Jump Starting a Vehicle
Follow these steps carefully to safely jump start your vehicle:
- Prepare the Vehicle: Ensure the vehicle's ignition is off and the parking brake is engaged.
- Connect Jumper Cables to Jump Starter: Insert the blue plug of the smart jumper cables completely into the EC5 port on the jump starter. The jump starter's indicator light should turn blue, indicating it's ready.
- Connect Clamps to Battery:
- Attach the RED positive (+) clamp to the positive (+) terminal of the vehicle's battery.
- Attach the BLACK negative (-) clamp to the negative (-) terminal of the vehicle's battery.
The smart cable indicator should show a solid green light, confirming a correct connection. If it shows a red light or flashes, check your connections.
- Start the Vehicle: Once the green light is solid, start your vehicle's engine within 45 seconds. If the engine does not start immediately, wait at least 1 minute before the next attempt. Do not crank for more than 3 seconds per attempt.
- Remove Clamps: After the vehicle starts, immediately remove the black negative (-) clamp first, then the red positive (+) clamp. Disconnect the jumper cables from the jump starter.
Forced Start Mode (If no green light):
If the smart cable indicator does not show a solid green light after connecting to the battery (e.g., due to a deeply discharged battery), you can use Forced Start Mode:
- Ensure the clamps are correctly connected to the vehicle battery terminals.
- Press and hold the "BOOST" button (or equivalent red button) on the smart cable for 3 seconds until the green light turns solid.
- Start the vehicle within 30 seconds.
- Once the vehicle starts, immediately remove the clamps as described above.
