Hilton, 25, wasn't required to appear in court.
She was arrested in Hollywood in September. Police said they saw her "driving erratically" and pulled her over for a field sobriety test.
The judge set a pretrial hearing for Jan. 23 and said the trial must begin by Feb. 23.
If convicted as a first-time offender, Hilton would likely face a fine, enrollment in an alcohol-rehabilitation program and a possible license suspension, according to prosecutors.
Hilton has starred with sometime-friend Nicole Richie in the reality TV show "The Simple Life."
