How to Jump Start an Automatic Transmission Car: A Step-by-Step Guide
Introduction
Jump starting a car is a common roadside repair that can be performed with the right equipment and precautions. However, it’s important to note that jumping an automatic transmission car differs from jumping a manual transmission car. In this guide, we will provide a comprehensive step-by-step process on how to safely jump start an automatic transmission car.
Safety Precautions
Before attempting to jump start your car, it’s crucial to take the following safety precautions:
* Park both vehicles close together, but make sure they are not touching.
* Engage the parking brake on both vehicles.
* Turn off the ignition and all electrical devices (e.g., lights, radio).
* Wear gloves and safety glasses to protect yourself from battery acid.
Equipment Required
* Jumper cables (minimum 8 gauge thickness)
* Another car with a working battery
Step-by-Step Process
1. Identify the Batteries
Locate the batteries in both vehicles. The battery in your dead car should be under the hood, typically on the passenger side. It will have two terminals marked with either a positive (+) or negative (-) symbol.
2. Connect the Jumper Cables
Connect the jumper cables in the following order:
* Red positive cable: Connect one end to the positive terminal of the dead battery and the other end to the positive terminal of the working battery.
* Black negative cable: Connect one end to the negative terminal of the working battery.
* Remaining black end: Connect the remaining end of the black cable to an unpainted metal surface on the frame or engine of the dead car. This is called a ground connection.
3. Start the Working Car
Start the engine of the working car and let it run for a few minutes. This will allow the battery to charge up the dead battery.
4. Turn the Ignition
Turn the ignition of the dead car to the “ON” position, but do not attempt to start it. Check if the headlights or any other electrical components come on. If they do, proceed to step 5.
5. Attempt to Start the Dead Car
Shift the automatic transmission to the “Park” position (or “Neutral” if your car has a neutral safety switch). Hold your foot firmly on the brake pedal and turn the ignition to the “Start” position. If the car starts, remove your foot from the brake pedal and let the engine run for a few minutes.
6. Disconnect the Jumper Cables
Once the dead battery has been charged enough to start the car, disconnect the jumper cables in reverse order:
* Black negative cable: Disconnect both ends.
* Black positive cable: Disconnect from the metal ground connection on the dead car.
* Red positive cable: Disconnect from both batteries.
7. Drive the Car
Drive the dead car around for at least 30 minutes to allow the battery to recharge. Avoid using excessive electrical devices (e.g., air conditioning, radio) during this time.
Troubleshooting
* If the dead car does not start after connecting the jumper cables, check the connections to ensure they are secure.
* If the cables spark or get hot, disconnect them immediately and seek professional help.
* If the battery in the dead car has a low fluid level, do not jump start it. Add distilled water to the battery and charge it using a battery charger before attempting to jump start it.
* If you are unable to jump start your car after following these steps, it may be necessary to have it towed to a mechanic for further diagnosis and repair.
Conclusion
Jump starting an automatic transmission car requires some specific precautions and steps compared to a manual transmission car. By following the instructions in this guide carefully and taking the necessary safety measures, you can safely jump start your vehicle if it has a dead battery.
