Why Knowing How to Open the Gas Tank Matters

Imagine you’re on a road trip, the sun is setting, and your Kia Soul’s fuel light starts blinking. You pull into a gas station, ready to refuel—but then you realize: you have no idea how to open the gas tank. It sounds like a small issue, but for new Kia Soul owners or those renting the vehicle, this moment can quickly turn stressful. Fortunately, opening the gas tank on a Kia Soul is straightforward once you know where to look. This guide will walk you through every step, from locating the release lever to safely replacing the gas cap, so you can refuel with confidence—no matter where your journey takes you.

The Kia Soul is a popular compact crossover known for its quirky design, practicality, and fuel efficiency. Whether you drive a first-generation model from 2010 or a newer 2023 version, the basic mechanics of accessing the fuel tank remain consistent. However, small differences in dashboard layout or cap design can cause confusion. That’s why understanding the process is essential—not just for convenience, but also for safety and vehicle maintenance. A loose or missing gas cap can trigger the check engine light, reduce fuel efficiency, and even lead to emissions issues. By mastering this simple task, you’ll save time, avoid frustration, and keep your Kia Soul running smoothly.

Step-by-Step Guide to Opening the Gas Tank on a Kia Soul

Let’s break down the process into clear, easy-to-follow steps. Whether you’re standing at the pump or just want to familiarize yourself with your vehicle, these instructions apply to most Kia Soul models from 2010 to 2023.

Step 1: Locate the Fuel Door Release Lever

The first step is finding the fuel door release lever inside the car. In the Kia Soul, this lever is typically located on the lower left side of the driver’s dashboard, just above the door panel. It’s usually marked with a small gas pump icon or labeled “Fuel Door.” The lever is often recessed into the dashboard trim to prevent accidental activation. If you’re having trouble spotting it, look for a small, vertical lever that you can pull toward you.

For example, in the 2015 Kia Soul, the lever is positioned just below the steering column and slightly to the left. It’s black or gray and blends in with the dashboard, so it’s easy to overlook if you’re not looking for it. In newer models like the 2020 Kia Soul EX, the lever remains in the same general area but may be slightly more prominent due to updated interior styling. If you’re still unsure, consult your owner’s manual—it will have a diagram showing the exact location.

Step 2: Pull the Release Lever

Once you’ve found the lever, gently pull it toward you. You’ll hear a soft “click” as the fuel door unlocks. Don’t worry—this isn’t a loud or dramatic sound. It’s designed to be subtle so it doesn’t startle you while driving. After pulling the lever, the fuel door on the exterior of the vehicle should pop open slightly, allowing you to access the gas cap.

It’s important to note that the lever only unlocks the door—it doesn’t automatically open it. You’ll need to manually push or pull the fuel door open from the outside. If the door doesn’t budge, make sure the lever was fully engaged. Sometimes, especially in colder weather, the mechanism can be stiff. A firm but gentle tug should do the trick.

Step 3: Open the Fuel Door and Remove the Gas Cap

Walk to the side of your Kia Soul where the fuel door is located—usually on the driver’s side rear quarter panel. You’ll see the fuel door has popped open a few millimeters. Gently push it open the rest of the way. Inside, you’ll find the gas cap, which is typically black or gray and made of plastic.

To remove the cap, twist it counterclockwise. Most Kia Soul models use a standard twist-off cap with no locking mechanism. You don’t need any tools—just your hands. As you turn, you’ll feel the cap loosen. Once it’s free, lift it off. Many models include a small tether or strap that keeps the cap attached to the fuel door, so you don’t lose it while refueling. If your model doesn’t have a tether, place the cap in a safe spot, like on top of the fuel door or in your pocket.

Step 4: Refuel and Replace the Cap

With the cap removed, insert the fuel nozzle into the filler neck and begin refueling. Be sure to use the correct fuel type—most Kia Souls require regular unleaded gasoline with an octane rating of 87 or higher. Avoid overfilling the tank, as this can cause fuel to spill and potentially damage the evaporative emissions system.

Once you’re done, it’s time to replace the gas cap. Screw it back on by turning it clockwise until you hear a clicking sound. This indicates that the cap is securely tightened. Do not overtighten, as this can damage the threads. A properly sealed cap prevents fuel vapors from escaping and helps maintain proper pressure in the fuel system. After replacing the cap, close the fuel door firmly until it clicks shut.

Model Year Variations and What to Watch For

While the basic process is consistent across most Kia Soul models, there are some subtle differences depending on the year and trim level. Being aware of these variations can help you avoid confusion, especially if you’re driving a used or rental vehicle.

First-Generation Kia Soul (2010–2013)

The original Kia Soul, introduced in 2010, features a fuel door release lever located in the same general area as newer models—lower left dashboard, near the door. However, the lever may be slightly less prominent and could be integrated into the trim without a clear icon. The gas cap is a standard twist-off type, but some early models may not include a tether. If you’re driving a 2010–2013 Soul, double-check that the cap is fully tightened after refueling to avoid triggering the check engine light.

Second-Generation Kia Soul (2014–2019)

The second-generation Soul brought a refreshed interior design, including a more intuitive dashboard layout. The fuel door release lever is easier to locate, often with a clearer gas pump symbol. The gas cap remains twist-off, but many models now include a tether to prevent loss. One notable feature in this generation is the improved sealing of the fuel system, which makes proper cap replacement even more important.

Third-Generation Kia Soul (2020–Present)

The latest Kia Soul models, starting in 2020, offer a more modern and tech-forward cabin. The fuel door release lever is still in the same location, but the interior materials and lighting may make it easier to spot at night. Some higher trims, like the GT-Line or EX Premium, may include additional safety features, such as a fuel door lock that engages when the car is locked. However, the basic operation remains the same: pull the lever, open the door, twist off the cap.

Electric and Hybrid Considerations

As of 2023, Kia has not released a fully electric or hybrid version of the Soul in all markets, but the Soul EV is available in select regions. If you’re driving a Kia Soul EV, the process for accessing the charging port is different from the gas tank. The charging port is usually located where the fuel door would be, and it’s opened either via the dashboard lever or a button on the key fob. Always confirm whether your vehicle is gasoline-powered or electric before attempting to refuel.

Common Mistakes and How to Avoid Them

Even with a simple process, mistakes can happen—especially under stress or in unfamiliar situations. Here are some common errors Kia Soul owners make when opening the gas tank, and how to avoid them.

Pulling the Wrong Lever

The Kia Soul has several levers and buttons on the driver’s side, including the hood release and parking brake. It’s easy to confuse the fuel door lever with the hood release, which is usually located further forward and marked with a hood icon. To avoid this, take a moment to identify the correct lever before pulling. The fuel door lever is typically closer to the door and has a gas pump symbol.

Forgetting to Turn Off the Engine

Always turn off the engine before opening the gas tank. Running the engine while refueling is not only dangerous—it’s also illegal in many places. The risk of fire or explosion increases when fuel vapors are exposed to heat or sparks. Make it a habit to shift into park, engage the parking brake, and turn off the ignition before stepping out to refuel.

Not Tightening the Gas Cap Properly

A loose gas cap is one of the most common reasons for a check engine light in modern vehicles. The Kia Soul’s onboard diagnostics system monitors the fuel system for leaks, and a poorly sealed cap can trigger a warning. Always twist the cap clockwise until you hear at least three clicks. If the light comes on after refueling, check the cap first—it’s often the culprit.

Leaving the Cap Unattended

It’s easy to set the gas cap down and forget it, especially if you’re distracted or in a hurry. Always use the tether if your model has one. If not, place the cap in a secure spot—like the cup holder or your pocket—so you don’t leave it behind. A missing cap can lead to fuel evaporation, reduced efficiency, and potential safety hazards.

Ignoring the Fuel Door After Refueling

After replacing the cap, make sure the fuel door is fully closed. An open fuel door can catch wind at high speeds, potentially damaging the hinges or latch. It can also allow dirt and moisture to enter the fuel system. Always give the door a firm push until it clicks shut.

Safety Tips for Refueling Your Kia Soul

Refueling is a routine task, but it’s important to follow safety guidelines to protect yourself, your vehicle, and others at the pump.

Turn Off the Engine and Electronics

Before opening the gas tank, turn off the engine and all electronic devices, including the radio and climate control. This reduces the risk of sparks and ensures the vehicle’s systems aren’t drawing power during refueling.

Stay Outside the Vehicle

Remain outside the car while refueling. Sitting inside with the engine off can still pose a risk if static electricity builds up. Plus, it’s easier to monitor the fuel flow and prevent overfilling when you’re standing nearby.

Avoid Smoking or Using Open Flames

Never smoke, light a match, or use any open flame near the fuel tank. Gasoline vapors are highly flammable and can ignite with even a small spark. This rule applies to everyone at the gas station, not just the driver.

Keep Children and Pets Away

If you’re traveling with kids or pets, keep them inside the vehicle or at a safe distance from the fueling area. Children may be curious about the gas cap or nozzle, and pets can accidentally knock over equipment. Use child locks if necessary to prevent them from exiting the car unsupervised.

Use the Correct Fuel Type

Always use the fuel recommended in your owner’s manual. Most Kia Souls are designed for regular unleaded gasoline. Using premium fuel won’t harm the engine, but it’s unnecessary and more expensive. Avoid diesel or E85 unless your vehicle is specifically designed for it.

Be Mindful of Weather Conditions

In cold weather, the fuel door release mechanism may be stiff due to condensation or freezing. If the lever won’t budge, try warming the area with your hands or using a gentle rocking motion. In hot weather, avoid prolonged exposure to direct sunlight while refueling, as fuel vapors can expand and increase pressure in the tank.

Troubleshooting Common Issues

Sometimes, despite your best efforts, things don’t go as planned. Here’s how to handle common problems when opening the gas tank on a Kia Soul.

Fuel Door Won’t Open After Pulling the Lever

If the lever clicks but the door doesn’t budge, the latch may be stuck. Try pushing or pulling the door gently while someone else pulls the lever. If that doesn’t work, check for ice, dirt, or debris around the latch. In extreme cases, the latch mechanism may need to be serviced by a technician.

Gas Cap Won’t Twist Off

If the cap is stuck, don’t force it. Apply a small amount of penetrating oil around the threads and let it sit for a few minutes. Then try twisting it again. Avoid using tools like pliers, as they can damage the cap or filler neck.

Check Engine Light Comes On After Refueling

This is often due to a loose or missing gas cap. Turn off the engine, remove the cap, and reinstall it securely. Drive for a few miles—the light may turn off on its own. If it persists, have the vehicle scanned for trouble codes at a service center.

Fuel Door Doesn’t Close Properly

If the door won’t latch, inspect the hinges and latch mechanism for damage or misalignment. Sometimes, the door can be bent from impact or wear. A dealership or body shop can assess and repair the issue.

Conclusion

Opening the gas tank on a Kia Soul is a simple task that becomes second nature with practice. By following the steps outlined in this guide—locating the release lever, pulling it, opening the door, and securely replacing the cap—you can refuel your vehicle quickly and safely. Understanding the differences between model years and avoiding common mistakes will help you stay confident behind the wheel, whether you’re a new owner or a seasoned driver.
