Are any other warning lights on the dash staying on? Check the brake fluid, be sure it's at the max mark, make sure the E brake is all the way off and check the brake lights for proper operation.

Under the hood is a diagnostic check connector, open the cover and locate the terminals Tc and E1, put a short jumper wire between these two, turn the key on, turn the cruise control switch on, the cruise control light should start flashing, if there is a trouble code the light will blink a pattern, for example a code 12 would be one blink and then two and so on, let me know how this goes
