How to Jumpstart a 2018 Jeep Renegade: A Step-by-Step Guide

The 2018 Jeep Renegade, a popular compact SUV known for its ruggedness and versatility, can sometimes face the dreaded dead battery. When this happens, you’ll need to know how to jump start your Renegade to get back on the road. This guide will walk you through the process, ensuring a safe and efficient jump start.

Gather Your Supplies

Before you begin, make sure you have the following items:

• Jumper cables: Choose a set of heavy-duty jumper cables designed for car batteries.
• A running vehicle: This will be your “donor” car, providing the power to jump-start the Renegade.
• Safety glasses: Protect your eyes from potential sparks or battery acid.
• Gloves: Wearing gloves will protect your hands from the cold battery terminals.
• A flashlight: This will be helpful if you’re working in low light conditions.

Locate the Battery

The 2018 Jeep Renegade’s battery is located in the engine compartment. To access it, open the hood and look for a black rectangular box with red and black terminals. The positive terminal (usually marked with a “+” symbol) will be the larger of the two.

Connect the Jumper Cables

Now, it’s time to connect the jumper cables. Follow these steps carefully:

1. Connect the positive (red) cable: Attach one end of the positive cable to the positive terminal of the dead battery in your Renegade. Make sure the connection is secure.
2. Connect the other end of the positive cable: Attach the other end of the positive cable to the positive terminal of the good battery in the donor vehicle. Again, ensure a secure connection.
3. Connect the negative (black) cable: Attach one end of the negative cable to the negative terminal of the good battery in the donor vehicle.
4. Connect the other end of the negative cable: Attach the other end of the negative cable to a metal grounding point on the Renegade’s chassis. This is usually a bolt or a metal bracket. Avoid connecting it directly to the negative terminal of the dead battery.

Start the Donor Vehicle

With all the cables connected, start the donor vehicle and let it run for a few minutes. This will allow the donor battery to charge the dead battery in the Renegade.

Start the Jeep Renegade

Now, try starting the Renegade. If the battery is sufficiently charged, it should start. If it doesn’t start immediately, try again after a few minutes.

Disconnect the Jumper Cables

Once the Renegade is running, disconnect the jumper cables in the reverse order you connected them.

1. Disconnect the negative cable: First, remove the negative cable from the Renegade’s chassis and then remove it from the donor vehicle‘s negative terminal.
2. Disconnect the positive cable: Next, remove the positive cable from the donor vehicle’s positive terminal and then remove it from the Renegade’s positive terminal.

Let the Renegade Run

After disconnecting the cables, let the Renegade run for about 15 minutes to ensure the battery is fully charged.

Safety Precautions

• Never connect the negative cable to the negative terminal of the dead battery. This can cause a spark that could ignite flammable gases.
• Avoid touching the battery terminals while the cables are connected. The battery terminals can carry a strong electrical current.
• If the cables are connected incorrectly, disconnect them immediately. Incorrect connections can damage the battery or the electrical system.
• If you’re unsure about anything, consult a professional mechanic.

Troubleshooting

If you’re unable to jump start the Renegade, there might be other issues at play. Here are some potential problems and solutions:

• Battery is completely dead: If the battery is completely dead, it may need to be replaced.
• Starter motor problem: A faulty starter motor can prevent the engine from turning over. You’ll need to have the starter motor inspected and repaired.
• Other electrical issues: There could be a problem with the electrical system, such as a blown fuse or a faulty wiring connection. A mechanic will need to diagnose and repair the issue.

Maintaining Your Battery

To prevent a dead battery in the future, take the following steps:

• Regularly check the battery terminals for corrosion: Clean the terminals with a wire brush or baking soda and water to ensure a good connection.
• Replace the battery when it’s nearing the end of its lifespan: A battery’s lifespan is typically around 3-5 years.
• Avoid leaving the headlights or other accessories on when the engine is off: This can drain the battery quickly.
• Use a battery tender or trickle charger: These devices can help maintain the battery’s charge when the vehicle is not in use.

When to Seek Professional Help

If you’re unable to jump start your Renegade, or if you suspect there might be a more serious issue, it’s best to consult a professional mechanic. They can diagnose the problem and provide the necessary repairs.

Looking Ahead: Maintaining Your Renegade

You’ve successfully jump-started your 2018 Jeep Renegade. Now, remember that proactive maintenance is key. Regularly check your battery, ensure all electrical connections are clean, and address any issues promptly. By doing so, you’ll keep your Renegade running smoothly and avoid future dead battery situations.

What You Need to Learn

Q: How long can I leave jumper cables connected to the batteries?

A: It’s best to disconnect the jumper cables as soon as the Renegade starts. Leaving them connected for an extended period can cause overheating and damage to the batteries.

Q: What if my Renegade’s battery is completely dead and won’t accept a jump start?

A: If your battery is completely dead and won’t accept a jump start, you’ll need to replace it. A mechanic can test the battery and confirm if it needs to be replaced.

Q: What other signs might indicate a failing battery?

A: Other signs of a failing battery can include slow engine cranking, dimming headlights, and electrical problems. If you notice any of these issues, it’s a good idea to have your battery checked.

Q: Is it safe to jump start my Renegade in the rain?

A: It’s not recommended to jump start your Renegade in the rain. Water can conduct electricity and increase the risk of electrical shock.

Q: How often should I check my battery terminals for corrosion?

A: It’s a good idea to check your battery terminals for corrosion at least once every six months, or more often if you live in a humid climate.
