New Yaris launch Edition - trouble configuring some driver assistance items

[AlfK]

I have just taken delivery of my new Yaris launch edition and have been trying to setup the Road Sign Assitance warning methods via the steering wheel Meter control switch, but have come across this 'issue':

Namely with the power switch ON and selecting the RSA function via the meter switch up/down buttons, then having chosen Visual/audible as the type of notification method I want for when I go over the speed indicated by whichever speed limit my car has recognised, as well as 3mph over limit as warning point, I press & hold the meter OK control switch to set this notification method, then the Return to previous screen button to bring me back to my required driver information screen, I drive off and get clear visual & beeps warnings when I go 3 miles over an indicated speed limit........all good there then !

However after stopping my journey, the next time I start another journey I get no visual/audible over-the- speedlimit warnings (unless I go through the above process again) !! However I find though that the 3 mph over the limit setting I also chose the first time has 'stuck', so the method of warning is not ' sticking'.

I have informed my dealer who has tested their test car and they say theirs keep these settings even after power on/off cycles............as we are locked down I am trying to fix this myself can anyone share similar 'issues' or tell me if I'm doing something wrong?

Please update your profile to include the new Yaris

I was the first to notice that problem in november and then got software to test and it worked by flashing the software

But it also brought another problem to light

Cars with hud display sometimes reads the sign in MPH or sometimes in KPH

They have done much research on my car but the problem has now gone to Toyota in Europe to get the solution

Not hold my breath

Hello Peter1951, I posted this a few months ago & assumed because I got zero response that no one else was having this issue !? 

However now, based on your addition, it seems I was correct to raise this as 'an issue'? 🤔👍

Also I'm glad someone else noticed this speed sign warning setting not sticking error bedsides me 👋👌

Could you advise me on the version of the software your dealer upgraded you too so I can add this to my list of 'jobs to give my dealer' when we come out of lockdown? 

Regards

Alf

just tell dealer to get on to toyota technical and you want to fix sent to snow toyota southampton

Got my Toyota dealer to perform a flash upgrade to my system couple of days ago (despite Toyota Customer Relations telling me one didn't exist for the new Yaris🤪).

Did the trick, and my speed sign recognition on the HUD now beeps and turns red if I creep slightly over, and also 'sticks' during ignition On/Off cycles.....my TPMS individual tyre pressure values now appear on the screen as well.

Then again it would have been the dealer's responsibility to make sure that any available updates had been done and the systems were working correctly before the car was collected by yourself.

[AlfK]

True.....in an ideal world I would have agreed with you, but surely Toyota 'Head Office' should have this info available to hand to answer specific customer's Qs when they ask for info on a specific topic?

[FROSTYBALLS]

Again in an ideal world that would be the case.

Customer relations people are not working in the technical department. They have limited technical knowledge and rely on a database of frequently asked questions. Your dealer is always the best person to contact if you have a technical question or issue. They will usually have a specialist who can look into things like this, get your service advisor to get you access to the QA person/technical person. If they don't know, they can search for technical bulletins, or can pass it up the chain if the problem cannot be fixed

Yes this is how I sorted it out following my negative response from Toyota CR . I think enough said on this I understand I contacted the wrong channel 😥

A further update on my issue with the RSA sign recognition settings not 'sticking' after an ignition Off/On cycle....

Following my software update by my local dealer (who have been great getting me this far with Toyota TME (those responsible for keeping all things Toyota in Europe  monitored/up-to-date)......It fixed the settings issue but has not entirely  left the RSA over the speed limit warnings behaviour to my satisfaction - namely now I have set the warnings to stay on & have been using my new car a little more now that lockdown has eased a bit, I am finding I am getting erroneous over the limit warnings, and there is no consistency to the errors whatsoever - so much so that it has necessitated me turning off the sound warning, leaving only a visual red sign warning on the HUD.

Reporting this to my local Northampton dealer - Steven Eagell, who have been great in helping me thus far, have again liaised with Toyota TME apparently the new Yaris also uses a GSM signal (something akin to GPS I think?) also along with actual speed sign recognition to make sure the speed limit the car 'sees' is a correct one - I suppose similar to a normal car's satnav or Google maps/waze does. This seems to be very signal dependent, and thus where this GSM signal gets weak, this is when things speed limit warning can go wrong. My dealer assures me Toyota TME are working on improving this system with perhaps another software update in the future.

Recently driving through road works the normal speed limit signs were blanked white and the car showed the blanked off white sign, I thought that was cool 😁

Hi,

I have had the same issues from day one, over speed warning not sticking and speed recognition in wrong unit. I have flagged this with my dealer but no progress on fixing the wrong unit issue. My car (Launch Edition) is nearly one year old and I find it unacceptable that this hasn’t been resolved. More and more cars are being made and not all have the same problems. Why can’t they just flash the software with the one from the factory? Has any of you had a resolution on this?

I have not played around with my RSA configuration (yet!), but I have noticed that it often shows the red 'speed warning' sign - even though I might be driving at or under the required speed.
Shows up particularly at 30 mph.
I might be doing 27mph or so in a 30mph zone and the sign on the dash will show a completely red 'over the speed limit'' 30 symbol. At other times it will correctly show a normal 'white' 30 speed symbol (if I'm not breaking the limit of course!).
Perhaps another software glitch?   

[AlfK]

Me too... My speed sign warning on my HUD often goes red even when I'm a good 10 mph under the recognised by the camera speed sign. 

I have had my dealer update my software because the settings weren't 'sticking' between switch-offs, however this has made no difference to the amount of false red signs I'm getting.... very annoying 😠

[Akos Sandorfi]

The same here. Apparently quite a few people reported this software bug. I am not sure how long it will take to roll out an update. I pester my dealer at least once a month. If I hear anything I will update you all on this issue.

I have seen the same issue on my Yaris Dynamic. When leaving home the first sign seen is a 40MPH. The RSA turns red when I go above 27 MPH! Occasionally it will read correctly but on the whole it always turns red long before reaching the speed shown on the sign. I reported this to my dealer who tested another model. They noticed the inconsistency too and told me "They all do this" so they think this is normal. I had no issues with this on my previous mk3 Yaris. Definitely appears to be a software error which Toyota need to fix ASAP.

Have you fed this directly back to Toyota GB?
