How do you dim the gage lights in a 2018 Hyundai Tuscon?

https://carmanuals2.com/hyundai/tucson-2017-owner-s-manual-106109 See page 3 - 62 .......... It’ll show and tell you all about it!

My car honestly doesn’t have that button, If I could upload pictures I would show you

That’s certainly odd - run it by the dealer for assistance is all I know to do .. There ‘IS’ a dash illumination dimmer - *somewhere* ... Good luck!

It’s in the manual as an optional switch so I think it’s becuase I have a lower tier model. The dealer probably has to do it

There ‘IS’ an operators dimmer switch on the vehicle ... You just haven’t found it yet! The option is how bright / dim the operator wants the dash lights to be.
