warning lights

I have a quick question.. In my 99 silverado the "low washer fluid" and "low coolant" lights have been coming on. I actually filled the washer fluid and coolant to acceptable levels. I was under the impression I had to use a sequence to reset the lights like when changing the oil. I can't find anything about it so I was wondering what ideas y'all had. By the way the warning lights are still on.
Thanks
