    "The belt tightened up around his waist and started to constrict his breathing, my wife had to call security and have them cut the seat belt strap to get him out."

    What happened is that he (or your wife) pulled the belt all the way out, whereupon it goes in non-automatic, "retract-only" mode. That's a safety featuer used when securing infant seats. All US seat belts in he past decade or so have this feature.

    What I don't get is why she had to cut the belt, rather than push the release button and release the silly thing? Either the belt was twised in such a way that the buckle wasn't accessible -- can happen in the way back, but not in the 2nd row captain's chairs -- or she panicked. Good thing they got the kid out.

    I don't think there's a problem with the belt design or mechanism.

    As far as valve stem seals, common problem on many cars, but haven't heard about problems with the 3.0 v6....

    The old carbon build-up line. It seems that is the fix all for anything. At least you got farther than I with this problem. 34 degrees here today and had the tap. Hang in there, good luck, and please try to keep us updated on what you find. I would like to get this fixed on my car also.

    2001 62,000 miles any others besides us 5 I think

    when the engine is cold the engine makes a noise, somewhat similar to tappets. when its warm its quiet. I think this is normal behaviour. The transmission also delays the shifts which also i'm told is design intent. 00 with 82k kms.

    Hi deepan:

    I really appreciate your comment. Would you please be more specific. Can you provide any realiable source where I can confirm your comment? My van (03, 18000Km) has the same problem. I took it to my dealer and left their overnight. Two top technicians in the dealership heard the noise and they don't know what it is. They claimed that they have never seen such engine noise problem before.
    deepan, I really appreciate your help. If I can get same commnet from Toyota techical support department, I will suggest that Toyota should put this "engine noise" and "transmission lagging" features on their car specification cause some customers like me don't like that kind of noise. I will definitely ask for my money back.

    thank you and looking forward to hearing from you.

    i cant think of any specific sites right now but this is from what ive read in the past and experienced over the yrs owning cars. This is not a sienna specific issue its more of a general issue. you might be better off doing some searches with words like, "cold engine, delay in shifting etc.. There is also another sienna specific site which can give you a lot more detailed answers. do a search on siennaclub and you'll find it. If i come across specific info i will post it.

    The only thing that is a bit specific to the sienna (3.0 v6) engine is that it doesnt take abuse very well. maintenance is a must. do the regular oil chnages and fluid changes and you should be fine. The early ones had PCV issues but 01 onwards the clearance was increased.

    Hi alnole3:

    My van has the same noise as yours. I would like to know what you found out.

    Thanks

    I bought a 2001 sienna XLE V6 in oct.'04 with 30K miles on it. I used premium 91 octane gasoline for about 4 months and then I switched to normal unleaded about 2 months back because of the recent surge in gas prices. The manual says the recommended fuel is unleaded gasoline, and then it says for improved Engine performance use 91 octane. Now, my Sienna's Engine feels rough and there is loss of power and is more noisy and sluggish than before. I did not noise any significant drop in mileage, though. Does using normal unleaded cause damage to the engine or the issue is only loss of power? Should I switch back to 91 octane? Any comments appreciated.
  • My Sienna 2001 power sliding door bounces back to the open position when we try to close it. I read in earlier posts that the rail needs to be adjusted to fix this problem. We don't have a warrantee (bought it used). Is there anyway to fix this on my own without taking it to the dealer?
  • deepandeepan Posts: 342
    i used 89 octane for the first yr. A waste of money. 87 Octane is all u need. you might want to add a can of fuel injector cleaner. do regular maintenance. I cant stress this enough. Infact i have an Avalon as well (identical engine) and both use 87. Ofcourse the Avalon is a bit faster off the mark because its carrying a few hundred pounds less.

    I've seen several people have this issue here and the response is to either
    1) change the battery (is this valid? can it be this simple?
    2) Change the A/F ratio sensor (Bank 1 Sensor 1)

    Here it mentions Bank 1 Sesor 1 being on the back, firewall side and requiring a special tool to replace (what kind of tool)?

    This seems to be different depending on year and size engine. Is this correct?

    I called the parts department and they mentioned two different parts. 89467-41030 and 89467-41040. They said P1130 refers to 89467-41040 and is located in the front, which contradicts what I have been reading. I'm assuming is due to being a 2001 and not a 2000 sienna.

    Thanks for you help! I don't want to get the wrong sensor if it can be avoided.

    Thanks!

    Hello all, just found this site. My wife and I recently bought a 2000 Toyota Sienna LE and it didn't come with an owners manual, there is a light in the gauges that looks like a cross section of a tire with 2 arrows point towards each other, and there is a button down between the door and the steering column that has the same symbol and says "Set" Can anyone tell me what the light and button is for?

    Thanks in advance...
  • jlewis99jlewis99 Posts: 2
    Yes, this means that a tire is low. If you check your tires and they are not low, reset the sensor by hold in that button for a few seconds with the key on.
  • santacruz1santacruz1 Posts: 11
    That is the low tire pressure warning light and the "set" button is to reset the tire pressure system after an event like anytime you take a wheel off the van. You have to look at the owner's manual to see how the reset is done because it's not as simple as just pressing the button.
  • user777user777 Posts: 3,341
    An owners manual is a good thing to have, but a better thing to actually read and consult periodically. It's also a good thing to have when you turn around and sell the vehicle. ;)

    You might want to call a local dealership...Toyota's web site indicates you can contact the Toyota Materials Distribution Center 1-800-622-2033 for documentation. You may be able to find something like this on EBay or from a store dealing with owner's manuals for vehicles.

    I'm not sure what will be the least expensive route to an owner's manual. Good luck.

    make sure the tires are at the correct pressure. Turn on Iginition and hold the "set" button for 5 secs. This will reset the light.

    Need to add something to aid in driving at night. Dark roads and Sienna's headlights don't make it, especially on a rainy night. Any recommendations for additional front lighting? Any caveats about wiring?

    Also found there are metal "shields" in the overhead lights on my 2000. Simply removing them by snapping off the plastic light cover and popping out the thin metal plate attached to it (with a small hole in it to let the light through) greatly increased interior lighting. Sorta made a spotlight like a floodlight.

    It's not changing the battery, as you post, but disconnecting it awhile to clear the CE code(s).

    The special tool you question accomodates the wire that comes out of the sensor. It makes R&R easier, but a standard wrench will work.

    Thanks all for the responses, that is what I thought it was and I do plan on buying an owner's manual, just haven't done it yet :)

    user777, tried the eraser trick and it seemed to work. Thanks for the suggestion!
