2. Step-by-Step Guide to Safely Jumping a Car
2.1. Safety Precautions Before Starting
Before you begin, ensure both vehicles are turned off. Engage the parking brakes and place the cars in Park (Automatic) or Neutral (Manual). Remove any metal jewelry and wear safety glasses to protect your eyes.
2.2. Preparing the Vehicles for the Jump Start
Position the cars close enough so that the jumper cables can reach both batteries, but do not allow the vehicles to touch. Open the hoods of both cars and locate the batteries.
