After an oil change or service on your DS 9 (2021–present), you can clear the service reminder yourself with the trip/reset button — no diagnostic tool needed. The maintenance spanner on the DS 9 is a service reminder, not a fault: it tracks distance and time toward the next scheduled service and lights up when that point is reached, so once the work is done the counter needs zeroing so the next interval is measured accurately. This guide covers what the reminder means, the exact reset sequence, and how to fix it if it won’t clear on the first attempt.
What the Service Light Means
The spanner (maintenance) symbol on the DS 9 is the car flagging that a scheduled service is due, calculated from distance travelled and time elapsed since the last reset. It usually shows briefly at start-up and then clears, or stays lit once the interval is genuinely reached. It is a prompt to have the routine work done — oil and filter and the associated checks — not a warning that something has broken. The DS 9 is a petrol plug-in hybrid, so short electric-only journeys can mean the engine sees relatively little running between fill-ups; the service schedule still applies on a time-and-distance basis regardless. Rather than quote a figure that might not match your car, confirm the exact interval in your owner’s handbook — what’s universal is that the reminder needs resetting after the service so the next countdown is accurate.
First, a Few Checks
Only reset after the service is actually done, so the interval stays accurate. Park safely, keep the engine off (you’ll switch the ignition on but not start the car), and have no tools to hand — you’ll use the reset button on the instrument cluster. Resetting before the work is complete just hides the reminder without the maintenance being carried out.
Resetting the Service Indicator
- Turn the ignition off.
- Press and hold the reset button on the instrument panel.
- While holding it, turn the ignition on — the ‘maintenance’ spanner appears and a countdown starts.
- Keep the button pressed until the countdown reaches ‘0’ and the spanner disappears.
- Release the button and turn the ignition off — the system is reset.
If the Reminder Won’t Clear
- Keep the button held the whole time — releasing before the countdown reaches ‘0’ cancels it, so wait for the spanner to disappear first.
- Hold the button first, then switch on — the order matters; the button must already be pressed as the ignition comes on.
- Switch the ignition on, not the engine — don’t start the car mid-reset; you only need the dash powered up.
- Cycle and retry — if nothing happens, turn everything off, wait a moment, and run the sequence again cleanly.
- A separate warning light? A fault stores a code — look it up on autodtcs.com.
Once the Reset Is Done
Once the countdown reaches ‘0’ and you release the button, the spanner should be gone at the next start-up and the service interval starts measuring again from full. Resetting only zeros the reminder — it changes nothing mechanical — so make sure the underlying service has genuinely been carried out. If the spanner reappears straight away, the sequence probably didn’t complete; repeat it carefully.
Reset Frequency
Reset the reminder after every service, once the work is finished. How often that falls depends on your mileage and how the car is driven — and severe-use conditions can shorten it — so follow the interval in your handbook rather than a single fixed number.
Frequently Asked Questions
How do I reset the service light on a DS 9?
Ignition off, press and hold the reset button on the cluster, switch the ignition on while still holding, keep holding until the countdown reaches 0 and the spanner disappears, then release.
Do I need a diagnostic tool?
No — the button sequence is owner-doable and needs no scan tool or workshop equipment.
Which button is it?
The trip-reset button on the instrument cluster — the same one you use to cycle the trip meter.
Does the plug-in hybrid drivetrain change anything?
Not for the reset — the button sequence is the same. The service is still due on a time-and-distance basis even if you cover a lot of miles on electric power, so keep to the schedule in your handbook.
It didn’t work — what went wrong?
Usually the button was released before the countdown reached 0, or it was pressed in the wrong order. Turn everything off and repeat carefully, holding the button first and keeping it held throughout.
Will resetting hide a real problem?
No — the spanner is a maintenance reminder, not a fault light. If a different warning symbol is showing, that’s separate and won’t be cleared by this reset.
