Idle 2.5 minutes in drive,(auto), neutral, (man) ac and rear defogger on.
Ac off, accelerate to 55 mph, 1/2 throttle.
3 minutes of steady state driving at 55 mph.
clutch engaged, (man), no braking, decelerate to 20 mph.
Accelerate to 50--60 mph at 3/4 throttle.

Decelerate, no breaking, end of drive cycle.
