Last week, my friend Sarah called me in a bit of a panic. Her Toyota Camry 2021 started flashing the maintenance light right after an oil change. She thought something was wrong with the car again. But actually, it just needed a quick reset. It made me realize how often this happens to people. So, let’s walk through how to reset maintenance light Toyota Camry 2021 in a simple way.
To reset the maintenance light on a Toyota Camry 2021, first turn the ignition to “ON” without starting the engine, then use the trip meter button to select “Trip A.” Turn off the car completely, then press and hold the trip meter reset button while turning the ignition back to “ON.” Wait until the light flashes and goes off. Release the button, start the engine, and confirm the reset.
Turn on the Ignition Without Starting the Engine
The first thing to do is get your Camry into the right mode. Sit in the driver’s seat and press the “Start” button twice—without pressing the brake pedal—so the ignition turns on but the engine doesn’t start. You’ll see the dashboard lights up, including the maintenance light. That’s how you know you’re in the correct mode.
Many people make the mistake of starting the engine here, but that won’t let you access the maintenance reset options. I once helped a neighbor who couldn’t figure out why the reset wasn’t working, and it turned out he kept starting the engine by habit. Little details like this matter a lot when dealing with modern dashboards.
It’s also a good time to glance at your display settings and make sure you’re in “Trip A.” This is where the system records your maintenance intervals. If you skip this part, the reset might not work. Keeping your car manual nearby can help too—it’s like having a map for every dashboard symbol.
Once you’re comfortable with the setup, take a deep breath and double-check everything. The ignition should be on, the engine off, and the trip meter showing “Trip A.” That’s your starting point for the reset process.
- Make sure not to start the engine.
- Dashboard should display “Trip A.”
- Keep your foot off the brake pedal.
- Turn ignition on by pressing Start twice.
Select the Trip Meter and Prepare for Reset
Now, let’s move to the trip meter button—usually found near the odometer. Press it gently until the screen shows “Trip A.” This step tells your car which display to reset from. Think of it like setting the right channel before tuning in the station.
It might seem like a small thing, but the Camry’s computer system reads commands only from specific screens. If it’s showing “ODO” or “Trip B,” the reset won’t register. I learned this the hard way when helping my cousin. We tried the process three times before realizing we weren’t on “Trip A.”
When you see “Trip A,” stop pressing any buttons. Leave it there for a few seconds. This ensures the display memory is ready to accept the reset signal in the next step. Try to avoid rushing—these systems need a short pause to sync.
If you’ve just changed your oil or serviced your car, this is a good checkpoint. Confirm that your maintenance is done before resetting, otherwise, you might forget future service reminders. It’s like hitting “snooze” on a task you haven’t actually completed.
- Keep display on “Trip A.”
- Don’t press any other buttons once selected.
- Confirm service is actually done.
- Wait a few seconds before proceeding.
Turn Off the Car Completely
Next, turn the ignition off completely. This clears the system’s active signals and prepares it for the reset command. The screen should go dark, and you shouldn’t hear any electronic humming. Think of it like giving your car a tiny “power nap.”
It’s important not to rush this. Let the car rest for at least 3–5 seconds. When I first learned this trick, I used to turn it off and instantly back on. That didn’t work at all. Just that short pause makes a difference in whether the reset signal sticks.
If you’re working in a quiet garage, listen carefully—you’ll hear the soft click when the electronics fully shut down. That’s your cue to move to the next step. Timing is everything in this process.
Also, keep your hands ready on the trip meter button for what comes next. The trick is about pressing and holding it at just the right time. Once you master it, you can do this whole routine in less than a minute.
- Turn the ignition off fully.
- Wait a few seconds for electronics to reset.
- Prepare your hand on the trip meter button.
- Avoid pressing anything else.
Press and Hold the Trip Meter Button
Now comes the most important part. With the ignition off, press and hold the trip meter reset button. Keep holding it firmly—don’t let go. While holding it down, press the “Start” button again twice to turn the ignition back on without starting the engine.
As you hold it, watch the dashboard carefully. You’ll notice a series of dashes appear, then a countdown, and finally, the maintenance light will flash and turn off. That’s your sign the reset worked. It’s satisfying to see that little light disappear after a successful try.
If the light doesn’t go away, don’t panic. It usually means the timing was off. Just repeat the process—turn off the ignition, and try again while holding the button from the start. Once you get the hang of it, it becomes second nature.
I remember showing this to my uncle, who thought it was some complex dealer-only process. His face lit up when the light finally went off. Sometimes, all it takes is patience and the right steps.
- Keep holding the trip button while turning ignition on.
- Watch for the flashing light.
- Don’t release the button too early.
- Repeat if timing is off.
Wait Until the Maintenance Light Turns Off
Now, keep holding the button until the maintenance light completely turns off. It usually takes around 5–10 seconds. You’ll see it blink and then disappear—that’s your car confirming the reset. Feels good, right?
If it stays on longer, that’s okay. Every Camry reacts slightly differently depending on how recently maintenance was done or how long the light has been active. Give it time and keep holding. Once it vanishes, release the button and smile—you’re done with the main part.
One thing to remember: don’t start pressing random buttons while waiting. Just stay patient. The system is updating internally, and too many inputs can interrupt it. I’ve seen people tap buttons out of curiosity and accidentally restart the whole process.
After the light goes off, you can finally start the engine. The maintenance reminder should now be gone. It’s a small win that saves you a trip to the service center and gives you a sense of control over your car.
- Hold until light turns off completely.
- Don’t touch other buttons while waiting.
- Release only after the light disappears.
- Start the engine and confirm reset.
Confirm the Reset and Check Everything
Once the light is gone, turn off the ignition and restart the car normally. Check your dashboard to make sure the maintenance light doesn’t reappear. If it stays off, congratulations—you’ve successfully reset it!
It’s good practice to also scroll through your trip meters and confirm everything is showing correctly. The display should now show “ODO” or “Trip A” with no extra alerts. If the light reappears, that usually means the reset wasn’t fully registered, so just repeat the process once more.
Sometimes, you might see a short flash of the light after restarting. That’s normal—it’s the system booting up. If it stays off afterward, you’re in the clear. Keeping a note in your maintenance log can also help track when you last did the reset.
Doing this yourself not only saves time but also gives you confidence about handling small car issues. You don’t always need a mechanic for simple dashboard signals. The more familiar you become with these routines, the smoother your maintenance experience will be.
- Restart and check if light is gone.
- Confirm display shows correct trip info.
- Repeat reset if light stays on.
- Note down reset date for record.

Frequently Asked Questions (FAQs)
Is it safe to drive with the maintenance light on?
Yes, it’s safe for a short time, but the light usually means your car needs an oil change or basic service soon. Driving long distances without checking could wear down engine parts. Think of it as a gentle reminder, not a panic alarm. Still, schedule maintenance quickly so the car runs smoothly and efficiently.
Can I reset the maintenance light without changing the oil?
You technically can, but it’s not recommended. The light is there to remind you of real maintenance needs. Resetting it without changing the oil might make you forget future services. It’s always smarter to change the oil first, then reset the light as confirmation.
Do I need any special tools to reset it?
No special tools are needed. Everything can be done using the buttons already in your Camry. Some people prefer using a diagnostic scanner, but it’s unnecessary for this task. Just follow the on-screen steps, and you’ll manage it easily from your driver’s seat.
Is the process different for hybrid Camry models?
It’s almost the same. The only difference is the dashboard layout and how long the countdown takes. In hybrids, the system might take a few extra seconds to confirm the reset. But otherwise, the same “Trip A” and ignition steps apply.
Can this be done if the car battery was recently changed?
Yes, but sometimes the system may need one extra reset cycle. After changing a battery, the car’s computer can temporarily lose stored settings. Just repeat the process once more to make sure the maintenance light clears fully.
Do I have to go to a Toyota service center for this?
Not at all. Toyota designed the reset process to be user-friendly, so owners can handle it themselves. Service centers can do it too, but doing it on your own saves time and a small fee. It’s simple, safe, and takes less than two minutes.
Is there any harm if I reset it too early?
Resetting it early doesn’t harm the car, but it might mess up your maintenance schedule. The car won’t track oil change intervals correctly. That’s why it’s best to only reset after completing the actual maintenance.
Can this method work for older Camry models?
For most 2018–2021 models, yes, it’s identical. Older models might have a different button layout or use a key-turn ignition instead of a Start button. But the same principle—Trip A, hold button, turn ignition—still applies with minor timing tweaks.
