does the cruise control buttons on the steering wheel light up when lights on

For safety concerns - It is considered that lighted ‘steering wheel’ controls aren’t necessary in lieu of operator acclimation. You’ll quickly become familiar enough with those controls to actuate without taking your eyes off the road > looking down at them trying to actuate while driving - which is naturally more distracting than occasionally glancing at the instrumentation - - therefore it is considered a safety concern.
