How to Change Km to Miles on a Nissan Altima

If you’ve recently moved from a country that uses kilometers to one that uses miles—like from Canada or Europe to the United States—you might be frustrated seeing your Nissan Altima’s speedometer and odometer display distances in kilometers. Or maybe you bought a used Altima imported from another region and want to switch the display to miles for easier understanding. Whatever your reason, changing kilometers (km) to miles on a Nissan Altima is simpler than you might think.

The good news? You don’t need to visit a mechanic, buy special tools, or reprogram the car’s computer. Most Nissan Altimas allow you to switch between metric and imperial units directly from the dashboard or infotainment system. The exact method depends on your model year and trim level, but the process is generally intuitive and takes less than a minute.

In this guide, we’ll walk you through step-by-step instructions for changing km to miles on a wide range of Nissan Altima models—from older versions with basic instrument clusters to the latest high-tech trims with full-color touchscreens. Whether you’re driving a 2010 Altima or a brand-new 2024 model, you’ll find the right method here. We’ll also cover troubleshooting tips, common mistakes to avoid, and answers to frequently asked questions.

Why You Might Want to Switch from Km to Miles

Before diving into the technical steps, it’s helpful to understand why so many drivers want to make this change. The most common reason is location. If you’re driving in the United States, the UK, or any other country that uses miles per hour (mph) as the standard unit for speed and distance, seeing your car display kilometers can be confusing and even dangerous.

Imagine you’re on the highway and your speedometer shows 100 km/h. That’s roughly 62 mph—but if you’re used to thinking in miles, you might misjudge your speed and risk a ticket or an accident. Similarly, when checking your odometer for maintenance intervals or resale value, seeing kilometers instead of miles can make it harder to interpret your car’s usage.

Another reason is personal preference. Some drivers simply feel more comfortable with one system over the other. For example, if you learned to drive in the U.S., you’re likely more familiar with miles, and switching your Altima’s display can make driving feel more natural.

There’s also the practical side of buying a used car. If you purchased a Nissan Altima that was originally sold in Canada or Europe, it likely came with a kilometer-based display. Converting it to miles not only helps with daily driving but can also make the car more appealing if you ever decide to sell it in a market that prefers imperial units.

Finally, some drivers make the switch for consistency. If you own multiple vehicles—say, a Nissan Altima and a Ford F-150—you might prefer to have all your cars display the same units to avoid confusion when switching between them.

Understanding Your Nissan Altima’s Dashboard System

To successfully change km to miles, it’s important to understand how your Nissan Altima’s dashboard and display system works. Over the years, Nissan has updated the Altima’s instrument cluster and infotainment system several times, which affects how you access settings.

Older Models (2007–2013): Analog or Basic Digital Displays

If you drive a Nissan Altima from 2007 to 2013, your car likely has a traditional analog speedometer with a small digital display for the odometer and trip meter. These models typically don’t have a full-color screen or touch interface. Instead, they rely on physical buttons—often located on the instrument cluster or steering column—to navigate settings.

On these older Altimas, the most common way to switch between kilometers and miles is by using the trip reset button. This small button is usually found on the side of the speedometer or near the gear shifter. It’s used to reset the trip odometer, but it also serves a dual purpose: holding it down for a few seconds can toggle the display units.

Mid-Range Models (2014–2018): Enhanced Digital Clusters

Starting around 2014, Nissan began introducing more advanced digital instrument clusters in higher trims of the Altima. These models often feature a larger central display that shows not just speed and fuel level, but also navigation prompts, audio info, and vehicle settings.

In these Altimas, the process of changing units may involve navigating through a menu system. Some models allow you to access settings directly from the steering wheel controls, while others require you to use buttons on the dashboard. The exact steps vary, but the general idea is the same: find the “Settings” or “Display” option and look for a unit selection menu.

Newer Models (2019–2024): Full Touchscreen Infotainment

The latest Nissan Altimas—especially those from 2019 onward—come equipped with a full-color touchscreen infotainment system, often running Nissan’s latest software. These systems are more intuitive and user-friendly, with clear menus and easy navigation.

On these models, changing from km to miles is typically done through the main settings menu. You’ll access the system via the touchscreen, go to “Settings,” then “Vehicle” or “Display,” and finally select your preferred unit of measurement. Some trims even allow you to customize the display layout, so you can choose whether to show speed in mph or km/h prominently.

Step-by-Step Guide: How to Change Km to Miles

Now that you understand the different types of displays, let’s get into the actual steps. Below are detailed instructions for various Nissan Altima model years and systems. Follow the method that matches your car.

Method 1: Using the Trip Reset Button (2007–2013 Models)

If you have an older Altima, this is likely the easiest and most reliable method.

1. **Turn on the ignition** – You don’t need to start the engine, but the car should be in the “On” position (dashboard lights illuminated).
2. **Locate the trip reset button** – This is usually a small black or silver button on the instrument cluster, often near the speedometer or on the steering column stalk.
3. **Press and hold the button** – Hold it down for about 5 to 10 seconds. You’ll notice the odometer or trip meter display start to blink or change.
4. **Watch for the unit change** – After a few seconds, the display should switch from “km” to “mi” or from “km/h” to “mph.”
5. **Release the button** – Once the change is complete, release the button. The new units will stay active even after you turn off the car.

💡 *Tip:* If nothing happens after holding the button, try cycling the ignition off and on again, then repeat the process. Some models require the car to be in accessory mode.

Method 2: Using Steering Wheel Controls (2014–2018 Models)

Many mid-range Altimas allow you to access display settings using buttons on the steering wheel.

1. **Turn on the ignition**.
2. **Press the “Menu” or “Info” button** on the left side of the steering wheel. This will bring up options on the instrument cluster display.
3. **Navigate to “Settings” or “Display”** – Use the arrow buttons to scroll through the menu.
4. **Select “Units” or “Measurement”** – This option may be labeled differently depending on your model.
5. **Choose “Miles” or “Imperial”** – Toggle the setting from kilometers to miles.
6. **Confirm your selection** – Press the “OK” or “Enter” button to save the change.

💡 *Tip:* If you can’t find the “Units” option, check under “Vehicle Settings” or “Driver Assistance.” Some models hide it in submenus.

Method 3: Using the Touchscreen (2019–2024 Models)

For the newest Altimas, the touchscreen is your best friend.

1. **Start the car or turn the ignition to “On.”**
2. **Tap the “Settings” icon** on the home screen of the infotainment system. It usually looks like a gear or wrench.
3. **Select “Vehicle” or “Display Settings.”**
4. **Look for “Units” or “Measurement System.”**
5. **Switch from “Metric” to “Imperial.”** This will change speed, distance, and fuel economy readings to miles and mph.
6. **Exit the menu** – The change takes effect immediately.

💡 *Tip:* On some 2022–2024 models, you may need to go to “Preferences” > “Units” > “Distance” and select “Miles.”

Method 4: Using the Combination Meter (Some 2016–2018 Trims)

A few Altima trims from this period use a combination of physical buttons and a small screen in the instrument cluster.

1. **Turn on the ignition.**
2. **Press the “DISP” or “INFO” button** on the dashboard or steering wheel to cycle through display options.
3. **When you reach the settings screen**, look for a gear or settings icon.
4. **Use the arrow buttons** to navigate to “Unit Settings.”
5. **Select “Miles” and confirm.**

💡 *Tip:* If the screen doesn’t respond, try pressing and holding the “DISP” button for 3 seconds to enter setup mode.

Troubleshooting Common Issues

Even with clear instructions, things don’t always go smoothly. Here are some common problems and how to fix them.

The Button Doesn’t Work

If pressing or holding the trip reset button doesn’t change the units, try these fixes:

– **Check the ignition position** – Some models only allow changes when the car is in accessory mode (ignition on, engine off).
– **Try a longer hold** – Instead of 5 seconds, hold the button for 10–15 seconds.
– **Reset the system** – Turn the car off, wait 30 seconds, then try again.
– **Consult the manual** – Older Altimas may have a specific sequence (e.g., press twice, then hold).

The Menu Option Is Missing

If you can’t find the “Units” setting in the menu:

– **Update the software** – Some 2019–2021 models received updates that added or relocated settings. Check with a Nissan dealer for a free update.
– **Check user profile settings** – On newer models, unit preferences may be tied to a driver profile. Make sure you’re logged into the correct one.
– **Try a factory reset** – As a last resort, reset the infotainment system to default settings (this will erase saved radio stations and Bluetooth pairings).

The Change Doesn’t Stick

If the display reverts to kilometers after turning off the car:

– **Ensure the change was saved** – Some systems require you to press “Save” or “Confirm” after selecting miles.
– **Check for software bugs** – A few 2020 models had a glitch where unit settings reset after updates. A dealer can patch this.
– **Try the process again** – Sometimes a second attempt works.

Tips for a Smooth Experience

To make the process as easy as possible, keep these tips in mind:

– **Have your owner’s manual handy** – Even if you don’t read it cover to cover, the quick reference section often has a diagram of buttons and menu paths.
– **Try the method when parked** – Don’t attempt to change settings while driving. Pull over safely first.
– **Be patient** – Some systems take a few seconds to respond, especially older models.
– **Take a photo of the dashboard** – If you’re unsure which buttons to press, snap a picture and compare it to online diagrams.
– **Ask for help** – If you’re stuck, visit a Nissan dealership or service center. Most will do this for free.
