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 
in 5th gear without using 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). 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.
