Look in the trunk, there is a cover over the light assembly - open and you will have access to change the light.
Which bulb are you trying to change?
hi i have smal question,how to change thermostat in Toyota echo 2000 thanks
When the fule light comes on, you have about 2 gallons of gas left (about 60 miles). I ran out of gas one time, and now my light comes on when I have one gallon left, so I have to refuel right away. Also, you can find a manuel from any Toyota Dealer.
See related link. Its not an Echo, but close enough.
For my 2002 Echo it is 3.7 Liters with a filter change.
