Thank you Jeh - Very good tips and very nice initiative...
Another Tip : I had my Windows Open and usually to close them we start the car and then close it. I had it closed by holding the Lock Door Button for 5 Seconds and keep it hold till all your windows are closed... Whoila! You have got it closed.
Click on the Display Button near the GPS on the dashboard and you if you touch the screen top & bottom atleast 5 times(its like touch it up & down very fast atleast 6 times) - the Diagnostic of the System will appear and you check you speakers, Amplifier, Music, GPS - if all are ok or needs cleaning or servicing. This is something that one of the Lexus advisors taught me...
We open the cars by touching the handle - when you leave you don't need to take out your remote - press the black rubber button on the handle and it will close.
Cheers!
