I'd suggest arrow buttons on the steering wheel to change the centre stack..this would be the case in both my car and the new Yaris.
I very much feel your pain by proxy as trying to get my father to go out and learn the Yaris.
Being a Toyota it has physical knobs for HVAC etc but he's gone from what would be a 0 star NCAP car to a 5 star NCAP car. In reality this means it beeps about a lot about things that are not always entirely obvious.
I am trying to be encouraging in a "it's a 6 speed manual car...just go out and drive it like one and get used to how it drives we'll figure the whizzy bits and bongs out if we need to" way but at the same time I absolutely get it.
It's got hill start assist...the instructions give no clue as to how it actually works. He has no real desire to find out in live traffic with the jeopardy of rolling his new car into someone else to concentrate the mind. I probably would or I'd find somewhere quiet to mess with it but he doesn't fancy it at present.
It has satnav which I had difficulty with.... nevermind him who has never owned a smartphone again I can absolutely understand ignoring it.
I think a lot of modern cars give so much information that knowing what's "for your information" and what's a problem becomes a skill. As does knowing where to find what and how to get it.
On the way back apparently his centre stack was displaying the lane keep assist and distance to car in front..which he didn't know it did and was distracted by as it was flashing various things and drawing lines as it saw them which may or may not have been pertinent.
I'm very much hoping once the strangeness has worn off a bit and we can go out and do some addressing of the immediate needs and set it up how he wants and leave it. I suspect it's all actually reasonably simple other than the Toyota proprietary satnav which is like a logic puzzle...but it's a lot of unknown things going on at once while he's attempting to get used to his first new to him car since 2005 so it's a bit too much at present.
I feel his "pain". Last week, with about 200 miles on the clock, we went out to my boy's house to the south of the city and I was really enjoying the experience. The car is lovely to drive, the ride is considerably more comfortable than the Ibiza and it pitches much much less on speed bumps. The Ibiza was particularly bad on them, trying to bury it's front end into the road as it came down off the "hump". There's also much less turbo lag when picking up from low revs as you accelerate away from said speed bump - I'm pretty sure this is courtesy of the variable vane turbo control as opposed to the Ibiza's more simple open and shut wastegate. Time will tell if it's going to be as reliable though?
All went very well on the outward journey and I was feeling very pleased and thought I was really beginning to settle in and "bond" with the new car. On the return journey, almost as we left the end of his road, an orange triangle with an orange exclamation mark illuminated on the "mini panel" between the speedo and rev counter. Nothing else to indicate what it might be so Mrs J hauled out the owner's manual and discouvered there are 3 pages of warning icons which can appear. I pulled into the first convenient side road, switched the engine off and started reading the book. Seems that this exclamation mark in orange is to draw your attention and there should be another lit to further narrow down what's at fault. Our's only had the exclamation mark though. The book lists it as a "warning symbol" and should be safe to drive to your nearest "specialist garage" - for which read "main dealer". When I started the engine again it didn't come back so we carried on (I'd nipped out and checked oil, coolant, brake fluid levels and had a good look around under the bonnet generally while we were stationary, but found nothing. It was dark so I'd checked all the lights too including the number plate lights) Anyway, after about 10 minutes more or less, the light came back on. Oh dear. continued carefully keeping an eye out for coolant temp, oil warning light etc, etc. Luckily we go right past the Skoda dealer so I nipped in on our way past. Unfortunately the workshop staff had all gone home but there were reception staff there handing back cars that had been in during the day for work. She was very nice and said she thought the workshop foreman was still in and went to find him. 10 minutes later she came back with him and he had a quick look at the car but the light had gone out again! He told me the exclamation mark in either orange or red should be accompanied by an identifier light which narrows down the area of concern. A red light must not be ignored and, depending on the fault light the car may need to be immediately immobilized - Ie, engine stopped. An orange light is a warning and it should be safe to continue driving but advisable to call at a garage as soon as possible. As only our exclamation light is lit with no "identifier"light to accompany it, He couldn't make any suggestions as to what the fault might be and it would need to go on the diagnostic machine. He was actually a very nice chap and when I told him I used to hold a similar position to him, but many years ago, so wasn't surprised to find he was late going home - not many workshop foremen get to walk out the door with the other men - We commiserated for a while about the foreman's "lot" and he then said, We've had a few lately with similar symptoms, where it's been something like a poorly seated side light bulb. If I were you, as it's only an orange warning, I'd just drive it around for a while and see if an identifier pops on. Ok. so we drove home. Now, with nearly 800 miles on the clock, the orange exclamation has not been seen again, let alone an "identifier" - and all levels etc are absolutely fine with the car running beautifully. I'd love to know what caused it though.
But 3 pages of identifier symbols? That's over 40 fault symbols that could appear on the dash with another 52 "information" symbols, like main beam, dip beam, lane assist, seat belts, air con, safe distance, 6 separate ones for cruise control state, etc, etc. There even seems to be a light to tell you no light is switched on!? although I haven't seen that one yet. surely this isn't necessary.
