  1. It's slightly different on my Touch2 compared to those instructions. Igntion in either accessory or ready mode. Hold media button, and while holding it switch headlights from Auto to Side Lights 4 times. Maintenance menu pops up...
  2. Fine here... I use it in cities and in the country.
  3. My thoughts exactly. Ask them to update it to the latest version to see if that fixes it. Or do it yourself. The Excel has free map updates for 3 years from the Toyota UK site.
  4. Check that there isn't a USB drive inserted that has any files other than folders and .MP3 files in the root folder. The system displays a "Loading..." message like that when it tries to install a software update from the USB drive, so it could be seeing a file there that it thinks is an update and is trying to extract it.
  5. When you Google for the carbon part number, the going rate for compatible parts from reputable brands is around £5. Even premium brands are £15. I wish OEM parts weren't so expensive.
  6. Connect your phone to the car via BlueTooth. Then select the BlueTooth source on the car's media system. Play music on your phone.
  7. If you absolutely must use Google Maps, the only solutions are to buy and install a custom head unit that supports Apple Play or Android Auto, there are a few of them out there, some good, some bad, and some even go so far as to keep other features like the reversing camera with the lines that move with the steering wheel - there are many threads about this over on PriusChat about this for the Gen 4. Or you can use a phone mount and just use your phone (you can send audio to the car's speakers via BlueTooth of you wish). So you still get your music, and you still get Google Maps with voice navigation, and your phone still charges, but you don't get a big built in screen. That being said, roads don't change much. Even in the past 30 or so years I've been driving only 2 roads have changed significantly on a 250 mile journey I take a few times a year - The new Queensferry Crossing near Edinburgh, and the A1/A66 roundabout at Scotch corner, for example. In the former case it makes no difference to navigation as you start on the same road and end up on the same road that you would have using the original roads. If you have even mediocre navigation skills, and ability to read road signs, it generally makes no real difference at all having map data that's even 10 years our of date. If you don't have these skills, they're very useful to have. I'm not trying to be condescending, but sat navs do fail, sat navs can be wrong, sat navs can't always adapt to unforeseen closures, sat navs don't always understand the rules of the roads like one way systems or roads you shouldn't travel on. Being occasionally forced to navigate using the traditional methods is a useful reminder. Furthermore, relating to that, there are issues using internet based navigation. Not everywhere has a 3G or 4G data signal. Specifically, when I travel to the Yorkshire Dales, sometimes the maps just stop working for up to 20 minutes at a time. Sure, you can pre-download a route in Google Maps before you leave, but that's a hassle, AND, if you need to divert significantly off that route due to traffic or accidents or road closures then you're screwed. I once used Google Navigation to travel to the dales and it was great until I turned off the M6 into the Lake District. From then on it was beyond useless.
  8. The SatNav receives traffic information from FM radio broadcasts, and if you have your phone connected and allowed internet access it will also download traffic information from the internet. It may have been routing you in a way as to avoid traffic congestion or to avoid road works, an accident, and so on. Sometimes these things clear before the data is updated. Does it happen every time? Or just occasionally? The loud beeping and red sign is definitely the automatic emergency braking system. You were probably closing the distance fast on a car (possibly parked). This happens quite a lot. Once it realises you're braking or turning and will not crash the warning disappears. If you continue to head towards the thing it's seen it will really slam on the brakes VERY hard. Mine's only done that once, and it absolutely 100% prevented a real crash when a car in front of me on a slip road joining 60MPH traffic decided to chicken out and stop dead in front of me while I was checking my blind spot and not looking ahead. Anyway, I commonly get false alarms if I am travelling towards a parked car on bendy roads. The system only looks straight ahead. Also the camera watches for what it thinks are people stepping out into the road. I've had it beep when kids have ran towards the kerb from the pavement and stopped suddenly, or people have stepped out from behind parked cars. Again - it's never needed to actually brake, but it definitely saw a real hazard most of the time.
  9. When stored in a sealed container, petrol does not deteriorate. However, when stored in something that's open to the air then it can. This is mostly caused by the ethanol, which is often added to petrol, releasing water as it comes in contact with the air. The water sinks to the bottom of your tank (as it's more dense than petrol) and then enters the engine where it can cause issues. Also, other additives, can also deteriorate or evaporate in contact with air, which reduces the quality of the petrol. It's these additives you're paying the extra premium for when you chose Shell (other than ethanol). Now a car's fuel tank is reasonably, but not perfectly, sealed from the air. At the very least, it must take in air as the fuel is used. So how long will it last in a car before going "bad" is anybody's guess, buy I would imagine a long time. Months to years.
  10. Remove the mechanical key from the fob. Stick a flat bladed screwdriver in the hole that the mechanical key came out of and twist to separate the two halves. Replace the CR2032 battery. Push the two halves back together. Insert the mechanical key. Done. This was on page 568 of my manual in the Electronic Key Battery section.
  11. Use a 3.5mm headphone to headphone lead and plug it into the Aux socket. You can power the Echo via the USB socket. An alternative, if you have an Android phone, is to install the Alexa app on your phone and connect your phone to the car via BT. When you long press the voice command button on your steering wheel, it'll pop up on your phone which assistant (i.e. Google Home or Alexa) you want to use for that action. If you select Alexa, you can then use your phone as an Echo instead. Although I've not tested this setup with anything over than asking it questions, so can't confirm it'll steam music for hours etc.
  12. Yes. But in the scheme of things, the difference won't be genuinely noticeable. They improve the aerodynamics. Less of a difference at low speeds, and more at high speeds. They also add weight so some of these gains are negated. While they do make a tiny difference, and while all these tiny differences do add up, removing one isn't a big deal. The weather, the way the music on the radio unconsciously affects your driving style, tyre pressure, and so on, all make way way bigger differences.
  13. The ICE will fire up for a number of reasons. I suspect in this case it's because your battery is full. When it's showing all bars full the ICE fires up to allow for engine braking, in lieu of regenerative braking. Otherwise drivers would get confused when they brake gently or take their foot completely off the accelerator and nothing happened at all until they pressed the brake pedal half way and suddenly the friction brakes would come on suddenly and quite hard. You can force this situation by going into B mode, but the Prius will do it automatically when the battery is completely full. That being said, several other factors could also be at play here that will cause the ICE to fire up. These include the cabin temperature being lower than the temperature set on the climate control, a large electrical power drain (e.g. rear demister, fan on high, heated seats, etc), or the engine temperature too low (it likes to stay warm to reduce wear). Also, if you are pressing your accelerator more than enough to get the accelerator gauge half way, then also the ICE will activate. Even a gentle hill can require more than 50% accelerator to maintain speed.
  14. Yep. Last few days here in the UK have been the hottest for February since records began. More like end of Spring temperatures.
  15. Same here. Had two much warmer days here and for an extra 10mpg on my fault averages.
