Maintance Required light on. How can I turn it off?

Take it back to the oil change place. Or check the oil. If a seal is leaking or oil filter was not tightened or put on correctly oil may have leaked out and you will blow your engine!

Is is there any oil leaking in garage or driveway or where you park?

When service to the emission control system has been completed slide the switch to the opposite position, turning off the warning light.
If the service was for the 120,000 mile interval remove the warning light bulb.

CAUTION: If the speedometer is to be replaced set the odometer to the same reading as the odometer being removed. (consult your local motor vehicle laws)

When The ( maintance required) light is on it is telling you that their is an electronic fault in the four wheel drive system.You will need to have a scanner hooked up to help diagnosis the fault. their are several micro computers and solenoids in the system and it would be to expensive to guess which parts my be required to make the system function correctly

there is a small switch behind one of the switch blank off plates to the right of the steering column. It is a very small switch about 6" deep into the dash, hard to find easy to reset.

Please see my tip at http://www.fixya.com/cars/r5932051-check_engine_light_check. These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

You could reset it by turning the ignition-key to 'ON'.
Then hold down the tripmeter knob until the
maintenance light goes off, that resets it.

Look at the owners manual it will tell you how to turn it off. But before you do that check your milage with the maintance interval list located in the owners manual. The maintance light goes on when a certain milage is obtained which will describe the type of maintence is required.

If you are speeking of the check engine light you can disconnect the battery for a few minutes then reconnect it and the light should go off.

I get many calls a week for this procedure...
This is really easy! Follow these directions:

Turn the key ON

Look at the odometer, and verify that it displays "ODO" and the total mileage traveled. If it is on "Trip A" or "Trip B", press the black stick next to the odometer to read "ODO", and the total miles traveled.

Turn the key OFF.

Press in, and HOLD the black trip meter reset button, hold it in.
DO not release it.

Turn the key ON, do not start the engine.
Observe the Odometer display. The total mileage traveled will disappear, and you will see 5 dashes, then 4, then 3, then 2, then 1 dash, and finally, 5 zeros. Then, the total mileage traveled will redisplay.

Release the black trip meter reset stick.

This completes the reset procedure, and it will be back on in 5,000 miles, to remind you of you next oil change.

If it is 4X4 and you re not going far. Put the transfer case in neutral. If it is 2X4 standard transmission, put it in neutral. If it is an automatic transmission you need to remove the driveline.
