Ome people put oil on the rubber seals around the doors. A better solution is to pick up some silicone spray and spay that on the seals. The spray can be found at automotive or big box stores (Depot).

If the dealer/mechanic did the service early the light will come on when service is DUE. Go back to him and have it turned off. Search the web someone may have the procedure posted. Usually simple. Google "Toyota service light reset" or "Toyota Maintence light reset" Try this one

1. With the car started (ignition on), set the LCD odometer readout to total mileage (not trip A or B).
2. Turn the car off (ignition key to the OFF position).
3. Push in AND HOLD the button/knob that switches the odometer
4. Turn key to ON position without starting the car. You will notice the maintenance light blink and go out.
5. Release the odometer button/knob.
6. Turn key to OFF position.
7. That's it! The "MAINT REQD" light has been reset to warn you to change your oil in another 5,000 or 7,500 miles or so.

I have a 2004 Toyota sienna some time my gas pedal wont go why can you tell me what I can do

That light on the toyota sienna is drumroll please,,,,,,,,,, the air in one or more of your tires is low!! It would have made more sense to have a picture of a tire or the word tire or whatever,,, not sure what that symbol actually is, but check the air in all your tires and One will most likely be much lower than the rest. The tire pressure on the sienna I believe is 35 psi all 4 tires, but you can double check by looking on your doors.

Replace your brake pads and or rotors

Heater sensors for what?

Fuses panels are placed in two locations - underneath the drivers side (you have to take the cover off the panel to access them) and underneath the hood.

check stop lamps is working. if its not working check stop fuse on fuse box located under the dashboard.

There's a website that has all this information about all this and manuals everything totally free there are many actually but I personally like few .. let me know if u need help thanks

I have both lights on in my 2004 van also I have the engine light on. i took it to the dealer and they found the Yaw Rate Sensor (Vsc & TRAC) bad. The part is about$ 405 and is under the drivers seat. The other problems is the Catalyst System (engine light) about $1000 for parts.I have about 147,000 miles on my '04 and the problems started about 130,000.
