The buttons are on both sides of the speedometer.Work had been done on this vehicle. Afterwards all lights on trouble panel came on. How do you reset computer in order to turn off these lights? Is there a code system that you need to follow? Symbols that are always on are: battery, coolant, oil, brakes, windshield washer, all along a strip underneath the speedometer cluster. Colors are red, yellow.

try turn ign. on,disconnect battery10mins.reconnect,start do not rev. allow to idle.will try to get further info.but this could be a dash problem.
