Perform 2 medium accelerations from zero to 45 MPH using moderate pedal pressure and slow to a stop. Perform 2 hard accelerations from zero to 55 MPH using heavy pedal pressure. When second acceleration cycle is completed, increase vehicle speed to 60 MPH and cruise for 8 minutes. Reduce speed to 50 MPH, continue cruising for another 3 minutes and slow to a stop.
