You can reset the maintenance reminder on a Lexus NX yourself, for free, from the vehicle’s own display or settings. No scanner or purchase is needed. The exact menu names and button sequence depend on the generation, the display and the engine, so I’m not going to invent labels that might not match your SUV. Below is the method that applies broadly, how to tell which reminder you’re dealing with, and what to confirm in your owner’s manual.
The NX has two distinct generations, a first generation from the 2015 model year through 2021 and a redesigned second generation starting with 2022. It’s sold as gasoline, turbo gasoline, hybrid and plug-in hybrid models, so the details really do vary.
First, Identify Which Light or Message You Actually Have
Before you reset anything, work out what the car is telling you. These are very different situations.
Maintenance reminders (informational)
A scheduled maintenance or oil change reminder is a message or indicator that you’ve reached a service interval. It isn’t a fault. The car is working fine, and it’s nudging you to book or perform service.
The wording and symbol differ by model year and display, so read the actual message on your multi-information display. Your owner’s manual explains the indicators for your exact vehicle.
Red oil pressure warning (act immediately)
A red oil can symbol, or a low oil pressure warning, is not a reminder. It means the engine may not be getting adequate lubrication. Pull over when it’s safe, shut the engine off and don’t keep driving. Check the oil level per your manual and call for assistance if the warning stays on or the level looks wrong.
Resetting a maintenance reminder will never clear this warning, and you shouldn’t try.
Check engine light (a fault)
The amber engine-shaped symbol means the system has stored a fault code. It has nothing to do with the service interval. Something needs to be diagnosed, and no reset menu will fix that. If it’s flashing, reduce load and get the vehicle looked at promptly.
Quick sorting rule: a reminder asks you to schedule service. A red oil warning asks you to stop. A check engine light asks you to diagnose something.
Resetting Does Not Do the Maintenance
This sounds obvious, but it’s the most common mistake. Clearing the reminder only restarts the counter. It doesn’t change oil, replace a filter or repair anything.
Only reset the items you’ve actually completed. If you did an oil change but not a tire rotation, don’t clear the rotation reminder just to make the screen look clean. Keep your receipt or a note of the date and mileage, which helps with warranty questions and resale too.
How to Reset the Reminder on a Lexus NX
Start with the free, owner-operated method, which is the vehicle’s own menu system. Lexus builds the reminder reset into the on-vehicle controls, and in general it works like the steps below. Treat these as the general order of operations, not exact button instructions. Your manual’s maintenance section gives the precise names.
General procedure (all NX generations)
- Finish the service first, whether that’s the oil change, a rotation or whatever the reminder covers.
- Park on level ground with the parking brake set and the shifter in Park.
- Put the vehicle in the ignition state your manual specifies for accessing settings. On hybrid and plug-in hybrid models, that normally means powering the system on so the READY indicator or ignition-on state is active. Confirm this in your manual.
- Open the maintenance or reminder settings through the multi-information display with the steering wheel controls, or through the touchscreen vehicle settings. Which one applies depends on your model year and equipment. Look up “maintenance” in the manual’s index to find the correct path.
- Select only the item you completed and choose the reset or clear option.
- Look for a confirmation, such as the message disappearing or the counter or interval returning to its starting state.
- Turn the vehicle off and back on. If the reminder doesn’t return, the reset took.
First generation (2015 through 2021) versus second generation (2022 and newer)
The first generation uses the older Lexus cluster and infotainment setups, and the second generation moved to a newer digital layout and a redesigned touchscreen interface. Because of that, the menu path to the maintenance reset is not the same across the two. Don’t follow a video or forum post for the wrong generation, because the buttons and screens may not correspond.
I’m not going to claim a specific model year does or doesn’t have a particular reset menu. If you open the maintenance section of your manual and don’t find a reset item for your reminder, that vehicle may handle it differently, and a Lexus dealer or a qualified independent shop can clear it for you.
Is there a separate menu for oil and scheduled maintenance?
Some vehicles let you reset the oil change reminder separately from other scheduled maintenance items, and some use one combined reminder. I can’t say with confidence which applies to every NX trim and year, so check the maintenance section of your manual for how your reminders are organized. If you see a list of items, reset only the one you serviced.
Gasoline Versus Hybrid NX Models
The NX has been offered with a 2.0L turbo four, a naturally aspirated 2.5L four, a 2.4L turbo four and hybrid setups, depending on generation. That mix includes the NX 200t, NX 300, NX 300h, NX 250, NX 350, NX 350h and NX 450h+. The reset concept is the same across them, but the engine, oil grade and capacity are not.
Hybrids deserve extra caution for the actual service work:
- The engine can start on its own when the system is in READY, so never work under the hood or underneath with the system active.
- Hybrid and plug-in systems have orange high-voltage cabling. Leave it alone, and don’t disconnect or cut into anything orange.
- A hybrid’s engine runs less than a gas-only model’s, but oil still ages with time and short trips. Follow the interval in the maintenance guide, not a guess based on how rarely you hear the engine.
If the Reset Doesn’t Work
Work through these before assuming something is broken:
- Wrong menu: You may be in a different settings screen. Go back to the manual’s maintenance section and follow the path for your model year.
- Wrong ignition state: Some menus only appear or accept changes in certain power states. Confirm the required state in the manual.
- Vehicle not parked: Many settings lock out while the vehicle is moving or out of Park.
- A different reminder is active: Tire rotation, battery, brake and other items may have their own alerts that are still due.
- Message returns right away: Re-check which item is flagged and whether you cleared the right one.
If none of that works, a Lexus dealer or a qualified shop can reset it. Other brands handle this differently, which is why a guide like resetting the service due indicator on a Subaru Outback or the oil life monitor on a Jeep Grand Cherokee won’t map onto your NX.
Doing the Oil Change Yourself
An oil change is a reasonable DIY job on most NX models, as long as you follow the manual for your exact engine. The manual lists the correct oil grade, capacity and filter, and those differ between the turbo, non-turbo and hybrid engines. Don’t rely on a generic “NX oil change” spec, and look at the oil filler cap and manual for the viscosity.
Here’s a practical checklist:
- Use the oil grade and approved specification in the manual, and measure the amount going in.
- Match the filter to your exact model year and engine. Search by those details and confirm fitment before you buy.
- Replace the drain plug gasket if the manual or parts guide calls for it, and tighten to the torque in the manual rather than by feel.
- Check the level after the change, using the method the manual describes, and look for leaks.
- Take the used oil and filter to a recycling location.
A low-profile pan helps with positioning under a crossover and makes the job tidier, so pick one whose capacity comfortably exceeds your engine’s oil capacity. This one is a sensible starting search:
Low Profile Oil Drain Pan
A low-profile drain pan makes it easier to slide under a crossover and catch the oil without a mess.
For filters, search for an oil filter and then confirm the part matches your model year and engine before ordering. If you’re building out a basic home toolkit, the must-have tools for every DIY car owner list covers the essentials such as sockets, a torque wrench and jack stands.
Of course, none of these supplies are required for the reset itself. The reset is just a menu action.
How Often Should You Service It?
Follow the Scheduled Maintenance Guide or the maintenance section of the owner’s manual for your model year and engine. Intervals can depend on driving conditions, so heavy city driving, short trips, towing or extreme temperatures may call for the more demanding schedule in the guide. Time matters as well as mileage, so don’t skip service just because you haven’t driven much.
FAQ
Will resetting the reminder turn off the check engine light?
No. They’re separate systems. The maintenance reminder is based on an interval, while the check engine light means a fault code has been stored and needs diagnosis.
Can I reset the reminder without changing the oil?
Technically the menu may let you, but you shouldn’t. The reminder is only useful if it reflects reality. Resetting it without doing the service means you’ll lose track of when the oil is actually due.
Do I need a scanner to reset it?
Not as a general rule. The first method to try is the vehicle’s own display or settings menu, as described above. If your manual doesn’t show a reset option for your reminder, a dealer or shop can handle it.
The red oil light came on after my oil change. Is that a reminder?
No, treat it as serious. Shut the engine off when it’s safe, check the oil level as the manual describes, and look for leaks, a loose filter or an incorrect fill amount. Don’t drive on it, and get help if you can’t find the cause.
