GLC 350e Service & Service Manual
Our 2025 GLC 350e is due for its first service A soon. Does anyone know if this service is any different from the service for ICE-only vehicles? I can't find much information online specific to plug-in hybrids and don't have a service manual.
I have two other gas only c300s that I've always serviced vigilantly. Can I get away with delaying the service for another 5-10k miles since the ICE engine has only been used for 19% of the vehicle's lifetime?

I took a quick look at the 2025 GLC 300 (including 350e) Maintenance sheet and there is at least one important item specific to the high voltage battery. That’s a check of the high voltage battery coolant level. See page 2 half way down. I wouldn’t delay the maintenance or your warranty could no longer be valid.
