I read where on some vehicles these have to be reset after tire rotation. Is this true with the LS460's?

I replaced my battery last week and soon after had TPMS warnings. A look in the owner's manual indicated I had to reset the TPMS whenever the battery has been disconnected. While reading further I did come across a section mentioning that you should not rotate the tires when the car is on as that can confuse the system and then you'd need to reset it (a very simple process). I am under the impression that you don't need to reset the TPMS if you rotate the tires with the car off but I could be wrong. I would expect a need to reset TPMS if you drastically change the pressures after tire rotation. Are you receiving any TPMS warnings on the dash?

You don't need to reset your TPMS after a tire rotation. It won't go off just because of that. I rotate my tires every 3k miles never had a problem.

Thanks guys...

There is no TPMS "Reset" switch on these cars. TPMS reset occurs each time the car's ignition is turned off and turned back on - all warnings and alarms are cleared.

The cars have a TPMS (benchmark) Set switch that is located under the dash on the driver's side. This switch should only be operated for benchmarking the TPMS as operation at any other time will compromise the safety advantage or increase the false alarms.

When rotating tires on cars that use the same benchmark pressure on front and rear, which is the most common configuration, there is no necessity to redo the benchmark for rotation. Conversely, if you use different pressures on front and rear then you would need to do the benchmarking each time the tires are rotated.

Cars that have the tire pressure localization type display would need to be benchmarked each time the tires are rotated if you want the display to have the correct locations as localization only occurs during the benchmarking. Localization is a novelty thing and has no impact on the safety provided by the TPMS. I am not sure but I think the localization type display began with the '13 models.

The owners manuals caution that the TPMS needs to be benchmarked if the battery is fully discharged or disconnected. I am not sure this is true as I suspect disconnecting the battery and reconnecting it sets all 5 benchmarks to 33 PSI but I always redo mine just in case. There is no way to display the benchmarks so if you are not sure how yours are set then you need to do the benchmarking yourself.

Yeah no need to reset TPMS when rotating, nor do you need to reset after a battery change.
