Reset the Service Indicator

The service reminder on your Chevrolet Trax (2013–2016) is part of GM’s Oil Life System, and it is telling you the engine oil has done its job — not that something has failed. When the oil life countdown reaches zero, the Driver Information Centre (DIC) shows a ‘Change Engine Oil Soon’ message, and on many cars a small spanner (wrench) symbol appears alongside. After the oil and filter have been changed, that counter has to be set back to 100% so the car can begin tracking the fresh oil. If you skip the reset, the message will keep nagging even though the oil is new, and you lose the accurate mileage estimate that the system is designed to give you. The good news: on the Trax you reset it yourself from the dashboard buttons in under a minute, with no scan tool and no trip to the dealer.

What the Oil Life Indicator Actually Means

GM’s Oil Life System is condition-based, not a fixed odometer trigger. Rather than counting down a set number of miles, it runs a software model that watches how the engine has been used — temperatures, engine revolutions, trip length, load and running conditions — and estimates how much useful life the oil has left as a percentage. That is why one Trax might reach 0% far sooner than another: lots of short, cold, stop-start trips age oil faster than steady, warm motorway miles. Because it is a live estimate, the only reliable way to know where you stand is to read the remaining percentage in the DIC, not to guess from the mileage since your last service.

The reset itself does not change your oil or inspect anything — it simply tells the car “fresh oil is now in the sump, start counting again from 100%.” For that reason it should always be done after the physical oil change, never before or instead of it.

Before You Begin

• Only reset after the oil and filter have actually been changed — resetting on old oil hides how worn it really is.
• Park on level ground, apply the handbrake, and put the transmission in Park (automatic) or neutral (manual).
• You need the ignition ON but the engine OFF. On a keyed Trax, turn the key to the “Run/On” position without cranking; on a push-button car, press Start once without your foot on the brake so the electronics wake but the engine stays off.
• Have the DIC steering-wheel / dash buttons (MENU and SET/CLR) to hand — that is all the tooling this job needs.

Resetting the Service Indicator

1. Turn the ignition on but do not start the engine.
2. Press ‘MENU’ and scroll until ‘Oil Life System’ appears.
3. Press and hold the ‘SET/CLR’ button until the service interval resets.

When it takes, the display confirms the reset and the Oil Life reading returns to 100%. If your Trax asks you to confirm the reset, follow the on-screen prompt with the same buttons before releasing.

If the Reset Doesn’t Take

If the message reappears or the percentage does not climb back to 100%, work through these before assuming a fault:

• Check the ignition is ON, engine OFF. If the engine is running the menu often will not let the value reset — switch off, set the ignition back to Run, and try again.
• Confirm you are on the right menu item. The value only resets while ‘Oil Life System’ is actually selected in the DIC, not the trip or another readout.
• Hold SET/CLR longer. A quick tap is ignored by design; keep it pressed until the display clearly acknowledges the reset.
• Don’t start the engine mid-reset. Complete the whole sequence with the engine off, then start up afterwards to check the message has gone.
• Cycle the ignition and repeat. Switch fully off, wait a few seconds, then turn the ignition back to Run and run through the three steps once more.
• A light that still won’t clear can point to a stored fault — look the code up on autodtcs.com.

After the Reset

Once the reset is accepted, the Oil Life percentage returns to 100% and the ‘Change Engine Oil Soon’ message clears from the DIC. The spanner/service symbol, if it was showing, disappears at the same time. From that point the car starts a fresh estimate and the percentage will gradually count down again as you drive. If the message is still there after you start the engine, the reset did not complete — repeat the procedure with the ignition on and the engine off.

How Often You’ll Need This

You reset the Oil Life System every time the engine oil is changed — no more, no less. Because the system is condition-based, there is no single mileage figure that applies to every Trax; the car works out the interval for you and shows it as the remaining percentage. In practice you change the oil (and reset) either when the DIC calls for it by reaching a low percentage, or at the maximum time/mileage limit set out in your owner’s handbook, whichever comes first. If in doubt, follow the service schedule in your Chevrolet handbook rather than a number you have seen quoted elsewhere — it is the definitive source for your engine and market.

Frequently Asked Questions

How do I reset the oil life light on a Chevrolet Trax?

Ignition on (engine off), press MENU and scroll to ‘Oil Life System’, then press and hold SET/CLR until it resets to 100%.

Do I need a tool or a dealer visit?

No — the whole reset is done from the dashboard MENU and SET/CLR buttons. No scan tool, app or dealer is required.

Why won’t my Trax oil life indicator reset?

Usually the engine was running instead of just the ignition being on, the ‘Oil Life System’ item wasn’t actually selected, or SET/CLR wasn’t held long enough. Switch off, set the ignition to Run, reselect the item and hold the button until it confirms.

Should I reset before or after the oil change?

After. The indicator tracks the life of the oil that is in the engine, so resetting before the change would tell the car the old oil is fresh.

What does the spanner (wrench) symbol on my Trax mean?

It is the service/oil-life reminder, not a breakdown warning. It appears when the oil life runs low and clears once the oil is changed and the system is reset.

Does resetting the indicator change my oil or fix a problem?

No. The reset only tells the car to start counting from 100% again. It does nothing to the oil itself, so it must follow an actual oil and filter change.

If a service- or oil-related warning light stays on after the reset, or the reminder keeps returning, your Trax may have logged a diagnostic trouble code — decode it on autodtcs.com.
