With a new arrival imminent, I've been trying to fit a bulky rear-facing baby seat behind the driver. This wasn't working, due to the "easy access" system retracting the driver's seat upon exiting the car.
Unfortunately, UK 3RX owners don't seem to have been trusted with the "Customization" option in the "Car Settings" menu, that Americans and others can use. Disabling the easy access feature is a dealer-only option.
Fortunately, I found the Carista App and OBD2 adapter, which is £15 on Amazon, which apparently makes available the full suite of Lexus dealer settings. I plugged in the adapter, opened the app, it took a while to download some data, and then presented a simple set of menus. Disabling the automatic seat retraction was a cinch. Happily, the steering wheel still retracts, which genuinely helps you leave the car comfortably. I found the seat retraction aspect wasn't really helping anyway.
In the process, I noticed another useful setting. I've found the light-sensing headlights to be lacking in sensitivity for my tastes. Headlights don't activate in the overcast late evening gloom, for example. Fortunately you can adjust the sensitivity using Carista! There are five levels, ranging from Darkest to Lightest, which are apparently a function of both light level and time. I tried Lightest, which was too sensitive. Lights were activated while stopping under the shade of a tree on a sunny morning, for example. But "Light" (4/5 sensitivity) has proved to be just right.
It's a trivial thing I know, but it's nice to have the car operate at your convenience isn't it? 🙂
That leads me to one final thing I came across while browsing the US Lexus forums, which isn't available as a dealer/Carista setting. If you press and hold the AUTO re-circulate button, a menu pops up on the screen that allows you to change the sensitivity of the smog sensor. It's too early to assess what effect this has had, but having to drive in London traffic, I've set it to the highest sensitivity. I want those diesel fumes out of my Lexus and our lungs!
