Need to turn off 2004 rx330 maintenance light; SUV has NAV too.

Yes you can reset at home:

1. To reset MAINT reminder light after engine oil replacement, turn ignition switch to OFF position with odometer showing ODOMETER READING. Turn ignition switch to ON position while holding down trip meter RESET button.
2. Hold trip meter RESET button down for at least 5 seconds until odometer indicates "000000" and MAINT reminder light goes out.

If you take your civic into a Honda dealer for regular maintenance they should reset it for you. Even most Lube shops do as well. But if you do your own vehicle services like oil changes (which is what that light is there for) then here's how you can reset it.

1. put your key in the ignition but do NOT turn it.
2. press and hold the Odometer/Trip button.
3. while holding the Odometer/Trip button, turn the key to the ON position but do NOT start the engine.
4. As you hold the Odometer/Trip button, after about 10-15 seconds the Maintenance required light should turn itself off.
5. Once the Maintenance required light is off, turn the key into the off position then release the Odometer/Trip button.

That should do it. Hope this helps

Instructions

1. • 1 Turn the ignition switch to "ON" without starting the engine.
     
   • 2 Press the trip odometer button to change the display to the total mileage.
     
   • 3 Turn the ignition switch to "OFF."
     
   • 4 Press and hold the trip odometer button. Turn the ignition switch to "ON."
     
   • 5 Release the trip odometer button when the oil change maintenance light resets.
     

1. With your car OFF, place your key in the ignition and turn to "On". Do not start the car.
2. Find the odometer button and press until it reads the total odometer setting, (not the Trip A or Trip B setting).
3. Turn the key to OFF.
4. Place your finger back on the odometer button, press and hold. At the same time, turn the key back to "On".
5. Hold the odometer button in until the MAINT REQD light goes out...should take about 8-10 seconds.

page 77 of the 2004 Lexus rx330 handbook...
(you will find the answer you are looking for in resetting your maintenance light.)
with the odometer reading visible, (not trip A or trip B..) turn off engine.

While keeping Odo/trip button depressed, turn ignition back on (not starting the engine) You will see dashes (instead of numbers) on your odometer disappearing one at a time. it will be replaced by 0's (zeros).. Release the Odo/trip button and your original mileage will come up....
And your done..... until the next oil change.

Thank you for using fixya and good luck

Ive never heard of a timing belt light, but there is a maintenance light that can be reset. Here the procedure:

To reset the maintenance reminder light: Turn the ignition switch to the "ON" position. Set the odometer/trip display to the odometer (ODO) mode. Turn the ignition switch off. Depress and hold the trip meter reset button while turning the ignition switch to the on position. The maintenance reminder light will, illuminate for 3 seconds, blink for 2 seconds, illuminate solid for 1 second and then turn off. Release the trip meter reset button. Turn the ignition switch to the off position. Turn the ignition switch to the on position. Confirm that the maintenance light goes out.
Let me know if this helped you out!

my mother in law's 2005 Toyota Camry to turn off the maintenance light after an oil change. push and hold the trip/odometer and turn the ignition key to the run position while still holding trip/ odometer switch and release trip/ odometer tun ignition switch off and light should be reset

a major service is due at 60000 miles. the light is just a reminder that maintenance is due. is it the message on the nav screen or the one on the dash cluster? if you want to turn it of, hold the trip/od button in while turning the ignition on, keep your foot off the brake, dont start the car. you will see dashes flashing where the od shows miles, hold until its done flashing. and the lite on the dash cluster will go out. it will come back on after 5000 miles. you can go online to lexus.com to review what the services are and what they involve.

Look in your owners manual and go to the part that explains the different symbols on your dash. Look for that service reminder and it should tell you what page to go to to learn more about that. Somewhere there should be some wording to the effect that "When you have your car serviced by a certified Toyota dealer they will reset it for you. In the event that someone other does your maintenance then this is the procedure to reset......."

reset: turn ignition on...push odometer button till it displays mileage on car...not trip milage but actual mileage. Turn car off. Open driver's door, press and hold odometer button....turn ignition to on....hold odometer button for 10 seconds....odometer display will show -----,----,---,--,-,0000000....maintenance lights are reset...lights will come on every 7500 miles to remind you to change oil and check fluids etec....

service light ? you mean check engine. . . .when the check enggine light turns on, tmeans somethigns broken( or just a loose sensor) if you dont have any skills with fixing the car bring it to a mechanic. . .. .

but if you do know how to tinker with your engine, buy a service manual from haynes. . . . 8)
