Toyota Sienna Maintenance and Repair (2004+)

    I just noticed that my 2005 Sienna XLE AWD model does not have a TRAC OFF button on the dash below and to the right of the steering wheel column. I looked in the manual, which describes the use of this button (to turn the traction control system off) for the 2-wheel drive Siennas. For the AWD Siennas, the manual writeup makes no mention of this button. I wonder why there is no capability to turn the traction control system off in the AWD Sienna?

    The Trac system IS your AWD system, turn it off, no AWD.

    Just had the seat heaters fixed. I did not notice the problem until i started using the heaters more often.


    They work great now!

    September 20, 2004

    Some 2004 model year Sienna vehicles may experience a concern where the driver and

    passenger seat heaters do not operate until the temperature control switch is turned to

    the high position. The following repair procedure has been made available to correct

    this concern.
  • Very sorry to hear about your terrible experience with your new Sienna. I am curious if the MORONS at the TOYOTA Dealer who had helped you informed you that there had been a RECALL ON 5000 Siennas? Relating specifically to the Fuel pump and the Fuel Tank. The problem should not have been unfamiliar to them and in turn you, but something tells me that there is a whole in their info. hwy.... Sorry you had trouble. Even more surprising is that they LET you OUT of your contract. But good for you.



    Happy Holidays

    I know there is a "Post your MPG" area, but I would like to hear of possible solution to a poor MPG on an '04 Sienna XLE Ltd. Is it possible that the tranny isn't getting into high gear? What should the RPM be at say 60 MPH? Any possible sensor problems? Any and all suggestions most welcome. Same drivers and conditions as on 2000 Sienna.
  • approximately 1800rpm at 60mph in 5th gear
  • after pushing the button to raise the power hatch it goes up and then comes down right away there seems to be no block age but just wondering if anyone else has had this problem ?? the side doors are working and we are not experiencing any other problems that I know of. Any help is appricated thanks and Happy holidays!!
  • Driving through a parking lot yesterday, traction control came on as I accelerated. Parking lot was wet. Engine died, and will NOT re-start.


    It is not getting fuel. Will turn over and run for 1 or 2 sec., then quits. Will continue to run as long as you stand in front and feed it starter fluid.


    It is cold here, 10-30 defrees F, so I added 24 oz. of gasline anti-freeze. No help either. Can't get it to a dealer until Monday. Seems like a computer signal or something related to VSC, will not send gas to the carbuerator. Any ideas? Please help! Thanks.

    The new emissions standards requires the gas cap to be sealed such that the tank will build a light vacuum. If the vacuum control valve in the gas cap is frozen shut the fuel pump will not be able to suck fuel from the tank....
  • Thanks for the idea. Unfortunately, it still will not run. Any other thoughts on it would be appreciated. Happy Holidays!

    We have an XLE Ltd, '04. With the factory-installed DVD, is it always necessary to reach back into the vehicle and turn on the DVD player to restart the movie after the engine has been turned off and on again? Is there any way to actually activite the DVD from the dash? (Actually, we find there are many features of the DVD that can only be activited from the DVD player itself, not from the dash. Is this correct?) Also, is there anyway to have the DVD put in the "CD" player behind the NAV up front and broadcast it to the DVD player in the back (as opposed to having to reach back and put it in the machine in the back?) Thanks.
  • I have the same questions about using Synthetic Oil. Also what should be the intervals for my first oil change? Thanks.

    You can control a lot of the functions of the DVD player via "softkeys" on the NAV screen after inserting the DVD and hitting the disk key twice to display the DVD video on the NAV screen. You still have to put the DVD in the player overhead and hit the "DVD" button on the remote to turn the screen on, but you can do everything else from the NAV screen. However, unless you've made the "DVD anytime" modification (which consists of interrupting the vehicle speed sensor wire and grounding the parking brake wire), you'll only be able to control it while the vehicle is stopped and the parking brake is on. The "big" Sienna forum has directions on how to enable it.
  • I live in Michigan and it is COLD! I own a 2004 Sienna. I have noticed that when ever we travel for any extended time that the passenger side window gets a layer of frost on the inside. It is the window next to the second row. I cannot get rid of it? It is the only window in the vechile like this at the time. Any solutions out there or similar problems?
  • Hi

    I was wondering why I was constantly dialing up my heated seat to the highest position. I called my dealer and, sure enough, my VIN is eligible for TSB #AC005-04. Dealer says wiring harness repair is required. I'm the first one they've encountered, and they 'need to order the tool.' No parts required, apparently.
  • does anybody know why the mileage on the odometer since i bought now has 150 miles and the mileage on the rear view mirror show 340 any ideas/thanks for the input
