Suzuki Vitara 1.4 Boosterjet (2018) - Automatic

Hi guys,

I pulled the trigger and bought a Vitara Boosterjet 2018 with 90,000km on it. It's been serviced at the Suzuki official shop, but I don't have all the invoices (only have for 2023, 2024 and 2025). As far as I see they haven't changed the:

1. Engine accessory drive belt

2. ATF

My question is, do you think it's a good idea to change the ATF at 90,000km presuming that it hasn't been changed so far? And should I change the transfer oil and rare differential oil (although it says to change it at 150,000km) for AWD.

Also, spark plugs + brake fluid probably should be changed?

Would appreciate your feedback. Thanks!
