Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course,
disengages the cruise control. But you don't need to
reset it.
Once you're going about 25 mph (40 km/h) or more, you
can move the cruise control switch from on to
resume/accelerate briefly.
You'll go right back up to your chosen speed and stay
there.
If you continue to hold the switch at resume/accelerate,
the vehicle will keep going faster until you release
the switch or apply the brake. So unless you want to go
faster, don't hold the switch at resume/accelerate.
