Why You Might Need to Reset Your 2018 Subaru Impreza

Before diving into the how-to, it helps to understand why a factory reset is useful. Over time, your Impreza accumulates settings, saved data, and personalized preferences. Sometimes these can cause issues. A reset clears out the clutter and gives your vehicle a fresh start. Here are some common reasons people look up how to reset a 2018 Subaru Impreza to factory settings.

Infotainment System Freezes or Glitches

The touchscreen in the 2018 Impreza can sometimes freeze or become unresponsive. This often happens after a software update or when too many apps are running in the background. A soft reset usually fixes this without erasing any of your saved data. If the screen stays frozen after a soft reset, a hard reset may be needed. This clears temporary files and refreshes the system completely.

Maintenance Light or Warning Messages

The maintenance light on your dashboard reminds you to change the oil. After an oil change, this light should turn off automatically. Sometimes it does not. A reset procedure clears the maintenance counter and turns off the light. Other warning messages, like a low tire pressure alert, can also be reset after the issue is fixed.

Selling or Giving Away Your Car

If you are selling your 2018 Impreza, you want to remove all personal data. This includes saved Wi-Fi networks, Bluetooth pairings, and navigation history. A full factory reset wipes all of this information. It also restores the audio settings, display brightness, and user preferences to their original defaults. This is a smart step before handing over the keys to a new owner.

After a Software Update

Subaru occasionally releases software updates for the infotainment system. After installing an update, some settings may revert or behave unexpectedly. Resetting to factory defaults ensures that everything runs smoothly with the new software version.

How to Perform a Soft Reset on the Infotainment System

A soft reset is the simplest and safest method. It refreshes the system without deleting any of your saved data. Think of it like restarting a computer. This is the first thing you should try when your touchscreen acts up. Here is how to do it on the 2018 Subaru Impreza.

Step-by-Step Soft Reset Instructions

1. Park your Impreza and shift the gear selector to Park.
2. Press and hold the power button on the infotainment screen for about 10 seconds.
3. Wait for the screen to go dark. The system will power off completely.
4. Wait about 30 seconds. This gives the system time to fully shut down.
5. Press the power button again to turn the system back on.
6. Check if the issue is resolved. The touchscreen should now respond normally.

This method works for most minor glitches. If the screen still freezes or shows error messages, you can move on to a more thorough reset. A soft reset does not erase any of your personal settings, radio presets, or paired devices. It simply refreshes the system software and clears temporary cache files.

How to Reset the Maintenance Light on a 2018 Subaru Impreza

The maintenance reminder light is one of the most common reasons owners search for how to reset a 2018 Subaru Impreza to factory settings. After every oil change, this light needs to be manually reset. The good news is that this process is quick and easy. You do not need any special equipment or a trip to the mechanic.

Resetting the Maintenance Light Using the Steering Wheel Controls

1. Turn the ignition to the ON position. Do not start the engine. Just push the key fob or turn the ignition switch to the ON mode.
2. Use the steering wheel buttons to navigate to the trip meter display.
3. Press and hold the RESET button on the steering wheel stalk.
4. While holding RESET, turn the ignition to the OFF position.
5. Keep holding the RESET button for about 3 seconds after turning the key to OFF.
6. Release the RESET button. The maintenance light should now be off.

If the light stays on, try the process again. Make sure you are holding the button long enough. Some owners rush through step 5, which causes the reset to fail. Be patient and hold the button for a full 3 seconds. This method resets the oil life indicator to 100%, giving you a fresh start for your next service interval.

Resetting Other Dashboard Warning Lights

Not all warning lights can be reset manually. The check engine light, for example, requires clearing the diagnostic trouble codes with an OBD-II scanner. However, lights like the tire pressure monitoring system (TPMS) can often be reset after you inflate the tires to the correct pressure. The 2018 Impreza has a reset button located in the lower left corner of the dashboard, near the driver’s side door.

How to Do a Hard Reset by Disconnecting the Battery

A hard reset is the most thorough method. It resets every system in your 2018 Impreza back to factory default settings. This includes the infotainment, climate control, power windows, and even the adaptive cruise control preferences. Use this method when a soft reset does not solve the problem. It is also the best option if you want to wipe all personal data before selling the car.

Step-by-Step Battery Disconnect Method

1. Turn off the engine and remove the key from the ignition.
2. Open the hood and locate the battery. The 2018 Impreza has a standard 12-volt battery in the engine bay.
3. Use a 10mm wrench to loosen the negative (black) battery terminal clamp.
4. Disconnect the negative cable and move it away from the battery terminal.
5. Wait at least 15 minutes. This allows the vehicle’s computer systems to fully power down and reset.
6. Reconnect the negative cable and tighten the clamp securely.
7. Start the engine and check if the systems are functioning properly.

After a hard reset, you may notice some changes. The clock will need to be set again. Your radio presets will be cleared. The power windows may need to be recalibrated. To recalibrate the windows, hold the window switch in the full-up position for 2 seconds after the window is fully open, then hold it in the full-down position for 2 seconds after it is fully closed. Repeat this for each window.

Resetting the Navigation and Audio Settings

The 2018 Subaru Impreza comes with a STARLINK infotainment system that includes navigation, audio, and smartphone integration. Over time, these systems can accumulate custom settings that cause problems. Resetting the navigation and audio systems individually can help without needing to perform a full factory reset.

Resetting Navigation Settings

To reset the navigation system, go to the Settings menu on the touchscreen. Look for the Navigation option and select Restore Defaults. This clears all saved destinations, home locations, and route preferences. The map data and GPS functionality remain intact. You simply get a clean slate for your navigation preferences.

Resetting Audio Settings

For the audio system, navigate to the Audio settings in the infotainment menu. You can reset the equalizer settings, balance, fade, and speaker levels to their factory defaults. This is helpful if someone else has been adjusting the sound settings and you cannot find the right balance. The reset restores the audio profile to how Subaru originally configured it.

Clearing Bluetooth Pairings

If you want to remove all paired phones from your Impreza, go to the Bluetooth settings menu. Select each device and choose Delete. This clears all paired devices and their associated settings. After clearing, you can re-pair your phone as if it were the first time. This is especially useful when selling the car or if a previous owner’s phone is still trying to connect automatically.

Common Mistakes to Avoid When Resetting Your Impreza

Resetting a vehicle can seem straightforward, but small mistakes can cause problems. Here are some common errors to avoid when resetting a 2018 Subaru Impreza to factory settings.

• Disconnecting the battery while the engine is running. This can damage the electrical system and fry sensitive electronics. Always turn off the engine first.
• Not holding buttons long enough. Many reset procedures require you to hold a button for 3 to 5 seconds. Releasing too early will cancel the process.
• Forgetting to recalibrate power windows. After a hard reset, the auto-up and auto-down features may stop working until you recalibrate them.
• Skipping the radio security code. If your audio system has a security code, you will need it after a battery disconnect. Without it, the radio will not turn on.
• Resetting when the battery is low. A weak battery can cause the reset process to fail or corrupt the system software. Make sure your battery is fully charged before attempting a hard reset.
• Not backing up paired devices. Before wiping all Bluetooth pairings, make sure you have the PIN codes for each device in case you need to re-pair them.

When to See a Professional

Most reset procedures can be done at home with no special tools. However, there are times when professional help is the right call. If your infotainment system completely fails to boot after a reset, there may be a hardware issue. If warning lights keep coming back after you reset them, there could be an underlying problem that needs diagnosis. A certified Subaru technician has the tools and software to run a full system diagnostic and identify the root cause.

Also, if you are uncomfortable disconnecting the battery or working under the hood, do not hesitate to visit a dealership or trusted mechanic. A professional can perform the factory reset quickly and safely. Many Subaru dealerships offer this service for free or at a low cost, especially if your car is still under warranty.

Frequently Asked Questions

How long does it take to reset a 2018 Subaru Impreza to factory settings?

A soft reset takes about 1 to 2 minutes. A maintenance light reset takes less than a minute. A hard reset by disconnecting the battery requires about 15 minutes of wait time plus a few minutes for recalibration. Most owners can complete the entire process in under 30 minutes.

Will a factory reset erase my saved navigation destinations?

Yes, a full factory reset will clear all saved navigation data, including home locations and recent destinations. A soft reset, however, typically does not delete navigation data. If you want to keep your saved destinations, use the soft reset method instead of the hard reset.

Do I need any special tools to reset my 2018 Impreza?

No special tools are needed for most reset procedures. You only need a 10mm wrench if you are disconnecting the battery for a hard reset. A soft reset and maintenance light reset can be done using the steering wheel buttons and touchscreen only.

Why won’t my maintenance light turn off after resetting it?

If the maintenance light stays on after a reset, the oil life counter may not have been properly cleared. Try the reset process again, making sure to hold the reset button for at least 3 seconds. If the light still does not turn off, there may be a sensor issue that requires professional diagnosis.

Can I reset my 2018 Subaru Impreza while driving?

No, you should always perform a reset with the vehicle parked and the engine off. A soft reset can be done with the ignition in the ON position, but the car should remain stationary. Performing resets while driving can distract you and may cause unexpected system behavior.

Will resetting my Impreza delete the software updates I installed?

A hard reset restores the infotainment system to its original factory software version. If you have installed a software update, a hard reset may revert the system to the version it had before the update. Check with your Subaru dealer before performing a hard reset if you have recently installed a software update.
