7. 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
in
D
(automatic) or 5th (manual). Do not use cruise 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).
8. Drive in city/suburban traffic for at least 10 minutes. When traffic conditions
allow, let the vehicle coast for several seconds without using the accelerator
pedal or the brake pedal.
9. Park the vehicle and leave the engine off for 30 minutes.
