2000 Acura RL Maintenance require light on

I got an Acura RL 2000 with the mainten. light on all time. I already read other topic related to my problem, only difference is the model year of Acura RL. and tried to do the same as you guys suggested: " push and hold Reset button then turn key to ON position for 10 sec...." but it did not work for my RL 2000 and Mainten. light still on. I do not have owner's manual. Please show me how to get rid of this light for my RL 2000. Thank you!
