TPMS?

[Peter S]

Just had a funny one. An orange indicator showing a section through a tyre and an exclamation mark lit up on the dash. Had to look it up and it said it was the tyre pressure monitoring system. This is strange because I thought this was not fitted as an option on the sport. Added  a couple of psi to each tyre and it went away so clearly it is fitted. Mind you it also has auto wipers and I didn't think that was an option on my car too!

Tyre Pressure Monitoring Systems became compulsory on vehicles requiring new Type Approval from 1st November 2012, and on all new vehicles from 1st November 2014. The Yaris comes into the second category.

Cheers for that. You learn something new every day!!!

A note on the TPMS - it works on delta pressure (i.e. it has no idea what 30 psi is, but it knows that if the pressure drops by a certain amount, it will alert).

I suggest you check all your tyre pressures are correct, then do a TPMS reset (there is a button underneath the steering column trim at the very bottom of the dash). It will ensure the TPMS alerts correctly. I think this must be done every time the tyre pressures are changed (i.e. if you inflated them to the correct pressure from a lower pressure). The manual has details on what to do.
