Most manufacturers incorporate this DTE feature to give you up-to-the-minute notice on how much more you can drive before you refuel. So, get comfortable and continue reading this article as we explain why your vehicle comes with this handy feature.

What Does DTE Stand for in a Car?

DTE in stands for Distance to Empty most cars. It’s a critical feature that car manufacturers include in vehicle designs to tell drivers about the distance they can cover before running out of gas. Simply put, it tells you the distance you can travel before refueling.

As you drive, the DTE reading adjusts in real time, providing an estimate that becomes more accurate as you continue your journey. As such, you can avoid the worry of running out of gas and enjoy a more relaxed driving experience by keeping an eye on your car’s DTE reading.

But then, note that this estimate depends on your current fuel efficiency. Don’t rely solely on the DTE because it might not be accurate, and you might need to refuel before reaching your destination.

Is DTE Accurate for Estimating How Far You Can Drive on Reserve Fuel?

No, the DTE reading in your car is just an estimate and not completely accurate. DTEs can be off by about 15 percent, meaning the reading might be up to 15% more or less than your car’s actual distance before running out of gas.

For instance, if your car’s DTE says 150 miles, you could have as little as 120 miles left before you run out of fuel. Regardless, the DTE is still useful, giving you a rough idea of your remaining fuel.

How Can You Calculate Distance To Empty in Car?

You can calculate your car’s DTE by first noting your current fuel level from the gauge. Next, you must determine your car’s fuel efficiency in miles per gallon (MPG) or kilometers per liter (km/L). Finally, divide your current fuel level by your car’s fuel efficiency to calculate your DTE.

This simple calculation helps you estimate how far you can drive before refueling.

Here’s a simple step-wise way to calculate DTE:

  • Check your car’s fuel tank capacity: Find out your car’s fuel tank capacity. This info is usually in your vehicle’s manual or online.
  • Note your vehicle’s current fuel level: Check your fuel gauge and see how much fuel is left in your tank.
  • Check fuel efficiency: Check your car’s fuel efficiency, often measured in miles per gallon (MPG) or kilometers per liter (km/L). You can find this in your car’s manual or online.
  • Calculate the DTE: Divide your current fuel level by your car’s fuel efficiency. For example, if your tank holds 15 gallons, you have 2 gallons left, and your car gets 30 MPG, the calculation is 2 (gallons) x 30 (MPG) equals 60 miles DTE.

Below is an example to help you understand better: Let’s say you’re driving a car with a 15-gallon fuel tank, and it’s currently showing 4 gallons of fuel left on your gauge.

Then, suppose your car’s fuel efficiency is 20 MPG. Using the formula, 4 (gallons) x 20 (MPG) equals 80 miles DTE. So, you can drive approximately 80 more miles before needing to refuel.

What Are the Factors That Affect the Accuracy of DTE Reading?

Several factors affect the accuracy of DTE readings in cars. These include driving conditions like traffic and terrain, fuel tank size, fuel gauge precision, the presence of a reserve fuel margin, environmental factors, driving style, fuel type, and vehicle maintenance. Knowing these factors helps accurately make sense of DTE readings.

Fuel Efficiency Variability

DTE relies on your car’s average fuel efficiency to make estimates. If your driving condition differs significantly from what the system expects, this can affect your vehicle’s DTE accuracy.

For instance, if you’ve been driving aggressively in heavy traffic or hilly terrain, your fuel efficiency may become lower than the system’s calculation, making the DTE less accurate.

Driving Style

Your driving habits significantly influence fuel consumption. Gentle acceleration and braking improve fuel economy, while aggressive driving habits can decrease it. Carrying a heavy load or towing can reduce fuel efficiency, impacting DTE accuracy.

Fuel Tank Size

The size of your fuel tank can influence the accuracy of your car’s DTE. Vehicles with small and average fuel tanks have less room for error in estimating DTE. A minor discrepancy in calculating fuel economy can lead to a larger perceived difference in DTE.

Fuel Gauge Precision

The precision of your vehicle’s fuel gauge also affects DTE accuracy. If your vehicle’s gauge is not precise, it can result in wrong readings.

Digital fuel gauges are more precise than analog ones, giving a more accurate representation of the remaining fuel level. Some vehicles may require calibration of the fuel gauge for optimal accuracy.

Environmental Factors

Environmental conditions like temperature and altitude can also influence DTE accuracy. For instance, cold weather can reduce fuel efficiency and lead to reduced fuel economy.

More so, driving at high altitudes can affect your engine’s performance and average fuel consumption. This makes DTE less accurate at higher elevations.

Reserve Fuel Margin

Car manufacturers often build a safety margin into the DTE calculation to prevent drivers from running out of fuel completely. This means that when your DTE shows zero, you may still have a small amount of fuel left in the tank. While this is a safety feature, it can affect DTE’s accuracy in estimating the distance you can drive on reserve fuel.

Car Maintenance

Your vehicle’s condition also affects DTE reading.

A well-maintained vehicle with regularly serviced components like the fuel system and air filters tends to achieve better fuel efficiency, contributing to more accurate DTE estimates.

How Do You Reset the DTE in Your Vehicle?

You can reset your vehicle’s Distance to Empty feature by entering the accessory mode without starting the engine. Next, locate the DTE display on your dashboard and select the option to reset or clear the DTE reading. Then, confirm the reset and power off the ignition.

But before resetting the DTE, you must park your vehicle safely and turn off the engine. It’s best to have access to your car’s ignition key or key fob. Different car models may have slightly varied procedures, so consult your vehicle’s manual for specific instructions.

Here’s a detailed guide on how to reset DTE:

  • Enter Accessory Mode: Place your key into the ignition or press the Start/Stop button to enter the accessory mode without stepping on the brake pedal. This allows you to power up certain vehicle functions without starting the engine.
  • Locate the DTE display: On your vehicle’s dashboard or instrument cluster, locate the DTE information display. It’s typically found near the fuel gauge or in the driver information center.
  • Access the DTE menu: Depending on your vehicle’s make and model, you may need the steering wheel controls, dashboard buttons, or touchscreen display to access the DTE menu. Refer to your car’s manual for specific instructions.
  • Reset the DTE: Once in the DTE menu, look for an option to reset or clear the DTE reading. The wording may vary, but it’s usually something like Reset DTE or Clear Distance to Empty.
  • Confirm the reset and wait for confirmation: After selecting the reset option, the system may prompt you to confirm your choice. Follow the on-screen instructions or use the appropriate control method to confirm the reset.
