5.2 Using the Car Jump Starter
Follow these steps to safely jump start your vehicle:
- Step 1: Insert the jumper cable into the jump starter port. Ensure a secure connection.
- Step 2: Connect the red clamp to the positive (+) terminal of your car battery and the black clamp to the negative (-) terminal.
- Step 3: Start your car engine. If the engine does not start immediately, wait 30 seconds before attempting again. Do not crank for more than 3 seconds per attempt.
- Step 4: Once the car starts, remove the clamps from the car battery within 30 seconds to complete the operation. Disconnect the black clamp first, then the red clamp, and finally remove the jumper cable from the jump starter.
