To change the wiper blades on your NIO ET7 (2022–2024), the arms first need to be lifted into their service position. You activate it from the central touchscreen so the wipers move clear of the bonnet.
The service position — sometimes called the maintenance or winter position — raises the wiper arms high off the glass and holds them there so you can work at the base of the windscreen. You reach for it whenever the arms need to be out of their normal parked spot: fitting fresh blades, standing the arms up before a frost so the rubber doesn’t freeze to the screen and tear when you first wipe, or clearing leaves and grit out of the scuttle. On the ET7 there’s no lever under the bonnet and no knack with the stalk — the arms are commanded up through a setting on the car’s multifunction display. It’s a deliberate, built-in feature, not a sign of any fault.
Why There’s a Service Position
At rest, the ET7 parks its wipers low against the bottom of the windscreen, where the arms sit partly beneath the trailing edge of the bonnet. That tidy parked spot is exactly what makes them awkward to service by hand. Try to lift an arm straight up from park and it fouls the bonnet lip before it reaches a useful angle — enough to bend the arm, strain the linkage, or chip the paint at the bonnet edge. Sending the car into service position first drives the arms up and away from that pinch point, so they stand clear of the panel and you have room to change the blades without forcing anything.
First, a Few Checks
- Keep the bonnet closed. The arms swing up high into the space above the scuttle, so the panel must be down before you activate the mode.
- Stop the car and switch the wipers off. The setting is meant to be used with the car stationary and the wipers idle.
- Free any frozen blades first. If the rubber is iced to the glass, clear it before you trigger the arms, or the motor works against a stuck blade.
- Have the new blades to hand so the swap is quick once the arms are raised.
- Work one arm at a time rather than trying to steady both together.
Moving the Wipers to Service Position
- On the multifunction display, select ‘Settings’.
- Select ‘Driving’.
- Select ‘Service position’ — the wipers move up clear of the bonnet.
- Lift the arms and swap the blades.
Returning the Wipers to Normal
When the new blades are fitted, fold each arm gently back down onto the glass first — never let one snap back on its own, as an unsupported arm can crack the screen. Then exit service position on the display, or simply operate the wipers, and the arms return to their normal parked spot under the scuttle. Give the glass a quick wet sweep to check the blades sit flat and wipe cleanly before you drive.
If It Doesn’t Work
- The car isn’t stationary. Bring it to a complete stop before opening the menu.
- The wipers were still running. Switch them fully off, then select the setting again.
- The bonnet is open. Many cars block the raised position while the bonnet is up as a safety interlock — close it and retry.
- The blades are frozen down. Ice locking the arms to the glass can stall the movement; clear it first.
- You’re on the wrong menu. The control sits under ‘Settings’ then ‘Driving’ — not the general wiper on/off screen.
- Nothing moved. Wake the display, confirm the car is on but stationary, and select ‘Service position’ once more.
Changing the Blades — What to Expect
With the arms raised, hold the arm steady with one hand while you release the old blade so it can’t spring down and strike the glass. Most blades use a simple clip or hook fitting: press the release tab, slide the old blade off the arm, and clip the new one on until it locks. If you’re unsure which length or fitting your car takes, check the handbook or measure the old blades before buying. Once the new blade is seated, lower the arm slowly back to the glass rather than letting it drop.
Frequently Asked Questions
How do I put the NIO ET7 wipers in service position?
With the car stopped, open the multifunction display and go to ‘Settings’, then ‘Driving’, then ‘Service position’. The arms rise clear of the bonnet ready for you to work on the blades.
Why can’t I just lift the arms from park?
Parked, the arms sit under the bonnet lip and won’t swing up far enough. Forcing one risks bending the arm or chipping the paint. Service position raises them clear and protects the linkage.
Do I need any tools?
No. Putting the wipers into service position is entirely a touchscreen setting — no tools involved. You’ll only need the replacement blades for the swap itself.
How do I get the wipers back down?
Fold the arms back onto the glass, then exit service position on the display or operate the wipers. They return to their normal parked position on their own.
Why won’t it enter the service position?
Usually the car isn’t fully stopped, the wipers are still on, or the bonnet is open. Make sure the car is stationary with the wipers off and the bonnet closed, then reselect the option.
Does using service position reset anything?
No. It only moves the wiper arms to a raised angle for maintenance. It doesn’t clear reminders or change other settings — the wipers simply return to normal when you exit it.
