Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course, shuts off
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 R/A briefly.
You'll go right back up to your chosen speed and
stay there.
If you hold the switch at R/A, 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 R/A.
