How to change the time on a Toyota Yaris

In this video we see how to change the time on a Toyota Yaris, specifically when it comes to switching from daylight saving time to standard time and vice versa. We go to the multifunction screen and press "settings": from there we go to press the clock, simply click on daylight saving time, and the clock will change the time for us, without doing anything else.
