Reset the Service Indicator

The service reminder on your Infiniti Q70 (Y51, 2014–2019) is exactly that — a reminder, not a fault. The instrument cluster keeps its own maintenance counter, and once you (or your workshop) have carried out an oil-and-filter change it needs to be zeroed so the countdown to the next service starts fresh. On the Q70 you can do this yourself in under a minute using the buttons on the cluster — no diagnostic tool, no garage visit, no tools of any kind.

What the Service Reminder Means

The Q70 tracks maintenance through the vehicle information display in the centre of the instrument cluster. Rather than a single warning lamp, it holds separate maintenance items — engine oil and tyre rotation among them — each with its own counter that runs down as you drive. When one reaches its limit the display prompts you that the item is due. It is not a diagnostic trouble code and it does not mean anything is wrong with the engine; it is simply the car telling you that the pre-set service interval has elapsed and it is time for the work to be booked in.

Because the reminder is a counter and not a live measurement of oil quality, the display keeps counting whether or not the oil is actually changed. That is why the reset step matters: doing the oil change without resetting leaves the countdown showing the old figure, and resetting without doing the oil change simply hides a reminder that is still due. Treat the two as one job.

Before You Start

• Do the oil and filter change first. Resetting only clears the reminder — it does nothing to the oil itself.
• Park safely on level ground with the vehicle stationary and the transmission in Park.
• Ignition on, engine off. You want the cluster and its menus powered up, but the engine must not be running while you make the change.
• No tools required. Everything is done with the buttons on and around the instrument cluster.

Resetting the Service Indicator

1. Turn the ignition on but do not start the engine.
2. Press the cluster menu button until ‘SETTINGS’ appears.
3. Scroll to ‘MAINTENANCE’ and confirm.
4. Scroll to ‘Engine oil’ and confirm.
5. Select ‘RESET’ and confirm — the interval is reset.

When the reset takes, the engine-oil counter returns to its full value and the maintenance prompt clears from the display.

If the Reset Doesn’t Take

• Don’t start the engine. The reset is done with the ignition on only; a running engine can stop the menu from accepting the change.
• Confirm each step. Scrolling to an item is not the same as selecting it — press the button to enter ‘MAINTENANCE’, again for ‘Engine oil’, and again on ‘RESET’.
• Make sure you are on the right item. ‘Engine oil’ is the one that clears after an oil change; other maintenance items in the same menu are separate.
• Cycle the ignition and repeat. Switch off, wait a few seconds, switch back on and work through the menu again from the start.
• A warning that won’t clear may be a stored fault rather than the service counter — you can look the code up on autodtcs.com.

What to Expect After Resetting

Once confirmed, the engine-oil maintenance item returns to its full interval and the reminder disappears from the display. The counter then begins counting down again as you drive, so nothing further appears until the next interval is reached. If the prompt is still there the next time you switch on, the reset did not register and the procedure should be repeated.

How Often to Reset It

Reset the engine-oil item every time the oil and filter are changed — no more, no less. The exact service interval for your Q70 depends on the engine, the market and how the car is used, so follow the schedule in your owner’s handbook rather than assuming a figure. Whatever that interval is, the on-dash counter simply mirrors it, and zeroing the counter after each oil change keeps the reminder honest.

Frequently Asked Questions

How do I reset the service light on an Infiniti Q70?

Ignition on with the engine off, then work through the cluster menu: SETTINGS > MAINTENANCE > Engine oil > RESET, confirming at each step.

Do I need a diagnostic tool?

No — it is done entirely from the dashboard buttons, with no tool and no garage visit.

Does the engine need to be running?

No. The ignition should be on so the cluster and menus are live, but the engine must stay off while you make the reset.

There’s also a tyre-rotation reset — is that the same thing?

No. Tyre rotation is a separate item in the MAINTENANCE menu with its own counter. For an oil change, select ‘Engine oil’; only reset the tyre item after the tyres have actually been rotated.

Should I reset before or after the oil change?

After. The indicator counts down toward the next service, so resetting it before the work is done would give you a false interval.

The reminder came back after I reset it — why?

Almost always the reset didn’t register — usually because the item wasn’t confirmed or the engine was started. Cycle the ignition off and on and repeat the menu steps, confirming each one.

If a service-related warning light stays on after the reset, it may be a stored fault rather than the maintenance counter — decode it on autodtcs.com.
