Quick answer
With the G9 in P and the wipers off, open Vehicle on the centre display and enable Front or Rear Wiper Maintenance Mode. The selected arm moves to service position and returns automatically when the mode is switched off.
Before you start
Close the front compartment and driver door, disable automatic wiping and protect the glass. Confirm the replacement blade and connector against the original part before removing anything.
- P is selected and the car is secure.
- Wipers are off.
- Front compartment and driver door are closed.
- No one will operate the screen or wiper stalk during the work.
What to do
Before you start, read the complete sequence. Follow these steps in order and stop if the vehicle shows a stronger warning than the one described here.
- Open Vehicle on the central display.
- Enable the relevant Front or Rear Wiper Maintenance Mode.
- Wait for the arm to stop completely. Lift it only as far as needed and support it throughout.
- Release the blade connector according to the fitted part, compare old and new, then install until the lock clicks.
- Lower the arm gently. Disable maintenance mode and confirm the arm returns without touching trim.
Expected result
You should expect the following result when the documented route is successful: The wiper returns to its parked position and clears washer fluid evenly. A correct blade remains secure, does not knock the bodywork and does not leave a large unwiped area.
If it still does not work
If maintenance mode is unavailable, recheck P, door/bonnet closure and the wiper-off state. Do not force the mechanism. If the arm is misaligned, the connector will not lock or the motor fails to park, use a service centre.
Safety and model boundary
Never release a bare arm against the windscreen or enable the mode while an arm is raised. The cited 2025 English handbook may use screen labels that differ on later XOS versions; use the equivalent Vehicle maintenance setting in the exact car.

What to record before asking for help
Write down the model, model year, current XOS version and the time the problem occurred. Add the exact display wording, the last action that worked and the outcome of each safe check above. For charging issues include the charger type and its indicator; for access issues include the key method used. Do not include a VIN, registration, account password, PIN or verification code in a public post.
Why this matters: menu names, hardware and behaviour can change with market, model year and XOS version. Record the exact wording shown by the car before contacting support. That gives a service adviser a reproducible symptom instead of a general description.
