Thank you very much! I will check my car and see if it is just like what you said.

Thanks for your help. Have you try to listen the vibration of the cell phone? The sound is very low and in low frequency range, but you can hear it. My car's strange sound just like that, very low, but I can hear it and feel it by touching the steer. The sound comes up from time to time, but only when I accelerating the car.

Hi everybody! Nice to join here, as you know, I am a freshman and I came from New Zealand. I got a Windom 3.0G recently and would like to ask some questions about my car. My car is 91 model imported from Japan, 94000 Kms roughly. Q1: some buttons feature. There are 3 buttons on my left-hand side when I am sitting in the driver seat. They are the following: 1) Terms: Sport or Norm 2) ECT-S PWR 3) ECT-S MANUAL Could any one can tell me what are they working for? I do know something about ECT-S, it is somthing like Electronic Controlled Transmission System. However, I don't the difference between "ECT-S PWR" and "ECT-S MANUAL". The first button I think should be about adjustment of suspension system, but how does it work? I could't feel any change while I was switching it between "Sport" and "Norm". Q2: How to control the Cruise Control System? There is a control handle under the steering wheel of the cruise system, and there are some words on that handle. They are: RES/ACC, SET/COAST, CANCEL, CRUISE ON/OFF. I already knew how to control part of them by working on it for hours. However, can someone tell me the meaning of: RES, COAST? Q3: strange sound when I am accelerating the car I will hear some slight strange sound just like the sound of my cell phone' vibration when I am accelerating the car. I can even feel some slight vibration by touching the steering wheel at the mean time. Is that means something wrong with the auto transmission box or the engine? Q4: stereo system's problem I found that the CD changer of my car fixed in the luggage box was gone after I got the car. I know it should be took it away by the car's former owner. I can't see any worth of owning a bare CD changer without the other necessary parts. Moreover, I found that the performance of the stereo system is very low. I could't feel any bass output even thought I turned the volume control and the bass control to the highest position, also the volume was at a unreasonable level as well. Beside description above, the sound is quiet clear and all features are working. It is the same sympton as you are using a amplifier with not enough power to drive the speakers. Could anybody can give me some idea about that? Is it the former owner also took away the original amplifier of the car? Or it is only the amplifier faulty. What can I do to improve the performance of my stereo system? Much appreciated for any information. Thanks in advance!
