At the outset of jury selection in any civil or criminal case, the court must deliver preliminary instructions that: (1) explain the purpose of the voir dire examination, (2) explain the difference between peremptory challenges and removals for cause, (3) summarize the nature of the case, (4) estimate how long the trial may last, and (5) indicate whether it is anticipated that the jury will be sequestered.
