The Hyundai Tucson is a popular car, but one aspect that might be confusing to new owners is how to open the gas tank. This is especially true for those who have rented the car and do not have access to the owner's manual. There are different types of fuel tanks on the market, some of which can be opened with the push of a button or pull of a lever, while others require you to push the gas tank lid itself. This article will explore the various ways to open the fuel tank latch on a Hyundai Tucson.

What You'll Learn

The fuel tank is located on the driver's side
The fuel tank on a Hyundai Tucson is located on the driver's side. To open the gas tank, you will first need to open the gas cap. To do this, lift the lever behind the driver's side floor mat. Then, remove the gas cap to access the gas tank. This two-step process is designed to prevent someone from being able to open your gas tank easily.
The location of the fuel tank latch is consistent with many other Asian car brands, which typically place the fuel filler door release inside the car, usually beside the driver on the floor by the driver's door area.
If you are unable to locate the lever behind the driver's side floor mat, there may be a small button to open the gas tank, which should be accessible to the driver. Check the door or dashboard panel to the left or right of the steering column, or somewhere along the center console. The button should have a picture of a gas pump on it, similar to the one located near the fuel gauge. Ensure that the ignition is on when you press the button, as it is electric and has been known to have electrical problems.
If you still cannot find the fuel tank latch, open the rear hatch and look on the plastic panel behind the rear seats, towards the hatch opening, on the same side as the fuel door.
It is worth noting that some users have reported that the fuel door can be pushed open anytime the car is unlocked. However, once the car is started or locked, the fuel door will remain closed.

There is no lock on the fuel cap or fuel cap door
To address this issue, some owners have suggested keeping the car doors locked when the car is parked outside. This is because, on some Hyundai models, if the doors are locked, the fuel door is also locked. For example, on the 2021 Santa Fe SEL, locking the car doors also secures the fuel door. It is reasonable to assume that this would be the case for the Hyundai Tucson as well.
Another suggestion is to install a locking gas cap. This can provide an additional layer of security and prevent unauthorized access to the fuel tank. Some older Hyundai models, such as the 2018 Sonata SE, came with factory-installed gas cap locks. However, it is unclear if this is an option for the Hyundai Tucson.
It is worth noting that the absence of a lock on the fuel cap door may be by design. Some users have observed that the fuel door can be pushed open when the car is unlocked, but once the car is locked or started, the fuel door cannot be randomly opened. This suggests that the fuel door is intended to be easily accessible when the car is in use, but secured when the car is locked or turned off.
While there may not be a built-in lock for the fuel cap door on the Hyundai Tucson, understanding these access controls and taking appropriate precautions, such as keeping the car doors locked when parked, can help enhance the security of the fuel tank.

The fuel cap door can be pushed open when the car is unlocked
The fuel cap door on a Hyundai Tucson can be pushed open when the car is unlocked. This is a convenient feature that allows easy access to the fuel tank. However, it's important to note that once the car is locked or started, the fuel cap door will remain securely closed and cannot be randomly opened.
The absence of a lock on the fuel cap and fuel cap door has been noted by some owners of the 2023 Hyundai Tucson SEL. They have observed that when the car is turned off, the fuel cap door can be pushed open without any physical key or button-based locking mechanism. This observation highlights a potential concern for vehicle security, particularly when the car is parked outside.
To address this concern, it's worth mentioning that the fuel cap door may remain unlocked as long as the key fob is nearby, thanks to keyless entry technology. Moving away from the vehicle with the key fob may cause the fuel cap door to lock automatically, providing an additional layer of security.
For older Hyundai Tucson models, such as the 2018 Tucson 1.6t AWD Ultimate, the fuel door required a lever located on the floorboard to the left of the driver's left foot. This design differs from the more recent models, where a simple push on the fuel cap door when the car is unlocked is sufficient to open it.
While the push-to-open mechanism offers convenience, some drivers may prefer a locking fuel cap door for added security. In such cases, installing a locking gas cap is an option. Consulting a Hyundai dealer or a trusted mechanic can provide specific recommendations for your vehicle.

There is a manual release cable on the driver's side
If you're looking for the fuel tank latch on a Hyundai Tucson, there are a few places it could be located. The first thing to note is that the fuel tank is located on the driver's side of the car. Now, to open the gas tank, you need to first open the gas cap. In some Hyundai Tucson models, there is a lever behind the driver's side floor mat that you need to lift to open the gas cap. In other models, there is a small latch or button in the driver's seat armrest that you push to open the gas tank door.
Now, if you're specifically looking for a manual release cable, one source mentions that there is a manual release cable on the driver's side, rear tailgate interior, under the pop-off plastic cover. However, another user mentions that they were unable to locate it and that there is no mention of an emergency release handle in the HEV section of the manual. So, it seems that the location of the manual release cable, if it exists, may vary depending on the specific model and year of the Hyundai Tucson.
If you are unable to locate the manual release cable and are still having issues opening the gas tank, you may need to refer to the emergency gas tank release procedure, which should be outlined in your owner's manual. Additionally, it's worth noting that some users have mentioned that the fuel door can be pushed open anytime the car is unlocked, but once the car is locked or started, the fuel door will remain locked.

The fuel door release is inside the car
If you're wondering how to open the fuel tank on a Hyundai Tucson, you've come to the right place. The fuel door release is inside the car, so there's no need to worry about any external buttons or levers. Here's what you need to do:
First, make sure your car is unlocked. The fuel door will only open if the car is unlocked. Once you've done that, you can proceed to the next step.
Now, you need to locate the fuel door release. In some Hyundai Tucson models, the release is located on the driver's side, behind the driver's side floor mat. Simply lift the lever behind the floor mat to open the gas cap. On other models, the release might be located on the floorboard to the left of the driver's left foot. So, take a look around the driver's seat area to find the release.
If you're still having trouble locating the fuel door release, don't worry. Some Hyundai models have the release located inside the car, near the driver's door. It could also be located on the door armrest or somewhere along the center console. Keep in mind that the release will usually have a picture of a gas pump on it, so look out for that.
In some rare cases, if you still can't find the release, you might need to open the rear hatch and look behind the rear seats on the same side as the fuel door. There should be a plastic panel there with the release. Alternatively, simply push down on the gas lid to release it. Make sure the car is unlocked, as a locked car will usually have a locked gas door as well.
So, to summarise, the fuel door release on a Hyundai Tucson is located inside the car. You can find it behind the driver's side floor mat, on the floorboard to the left of the driver, or somewhere near the driver's door. Remember to look for the gas pump symbol. If all else fails, simply push down on the gas lid or check behind the rear seats. Happy driving!
