Hi All,

Hope everyone is doing well. I just picked up a 2023 Kia Forte GT Automatic DCT w/ GT2 Package in Steel Grey. Has been a great car so far. Just a few questions I thought maybe I could receive some input on:

1) Is there a specific break-in period for the vehicle? I hear different advice on this, with the most common answer being to keep the vehicle between 2k-4k RPMs for the first 600 miles. It is also reported that during this period, the transmission is a little jerky, especially at low speeds, but that this is normal. Would anyone know if this subsides after the break-in period or as more miles are put on the vehicle?

2) Is there a way to keep the active lane steering assist on permanently (steering wheel symbol) instead of having to manually activate it every time the vehicle is turned on? I have the same question for the Auto Hold feature as well.

3) The rubber beltline trim surround on the doors are composed of some sort of rubberized plastic. Should I start applying a protectant/Armor All-type applicator to protect it from fading? If so, are there any recommended cleaner/application treatments that work best for this type of material that would not damage the paint?

4) For each service interval, the manual indicates an oil change should be accompanied by a fuel additive treatment. Does anyone know what type of fuel additive is recommended?

I may have more questions the more I drive it, but these are all I can think of at this time. Attached are some initial photos (more to follow). Thank you in advance for the input!

Use mineral oil for rubber and plastic trim. You can get it at any drug store and it’s cheap. It has no smell and doesn’t leave residual stickiness like armor all
