8. Select a nearby, lightly traveled major highway where you can maintain a speed
of 50 to 60 mph (80 to 97 km/h) for at least 20 minutes. Drive on the highway
D (continuously variable transmission) or 5th (manual). Do not use cruise (
in
control. When traffic allows, drive for 90 seconds without moving the
accelerator pedal. (Vehicle speed may vary slightly; this is okay.) If you cannot do
this for a continuous 90 seconds because of traffic conditions, drive for at least
30 seconds, then repeat it two more times (for a total of 90 seconds). While the
vehicle is traveling in this speed range, shift to 6th gear and then accelerate and
decelerate 5 times, each time making sure you do not exceed 60 mph (97 km/h).
9. Park the vehicle and let the engine idle for 1 minute without using the
accelerator pedal.
10. Park the vehicle and leave the engine off for 30 minutes.
