Purchased used vehicle from a Toyota Dealership on or about March 27, 2021. The dashboard illumination on the 2017 Toyota Sienna only appears to operate when the vehicle is turned on AND the front headlight selector is moved to the on or automatic mode. I do not believe it is a standard feature for any vehicle to NOT illuminate the dashboard without the headlights being turned on. Issue: With no illumination of the tachometer and speedometer these items are nearly impossible to see. That naturally forces the human eye to remain looking down slightly longer than normal which can possibly result in an accident. If it is a sunny day with no need for headlights this issue is now exacerbated because the bright sunlight often causes drivers to wear tinted or dark sunglasses rendering the dashboard nearly 100% black. So, my question is a simple one: On the 2017 Toyota Sienna, with the standard feature set included as indicated under VIN - [XXX], should the dashboard lights illuminating the tachometer and speedometer areas turn on immediately and automatically when the vehicle is started? On the vehicle, the dashboard lighting only turn on when the headlights are turned on or set in the auto-headlight mode-??both of which are not my choice. I want see my dashboard data automatically and without having to drive with my headlights turned on. This is a poor dashboard visibility standard for this make, model and year Sienna.

July 2019, speedometer gauge is not visible in daylight with the lights off. Toyota service altered the light configuration so that now the auto light feature and the lights on warning does not work. Dealer advised I must use parking lights switch selection in order to see speedometer guage in daylight. The car does not work as advertised and is a "driving while distracted" significant safety risk as no-one cannot see the speedometer during daylight driving with the lights off.

Instrument panel gauges hard or impossible to read during daytime hours unless full sun is out. Can not see the speedometer nor other indications. Instrument panel lighting come on when headlights or parking lights on, but at day time when they are off, the terribly designed dark cluster is impossible to see. Due to the dark design of the cluster, I recommend that the vehicle cluster illumination to be on at all times during vehicle operations regardless the position of the headlight switch.

There is a safety design flaw in this vehicle. The dashboard instrument lights will not light up in the daytime making it very difficult to read the speedometer and other instruments resulting in distracted driving. Toyota refuses to correct this design flaw.
