Here's the second way to go to a higher speed:
1.
Move the Cruise switch from ON to WA (Resume/Accelerate). Hold it
there until you get up
to
the speed you want, and then release the
~
switch.
2. To increase your speed in very small amounts, move the switch
to RIA
(Resume/Accelerate) for less than half
a second and
then release it.
Each time you do this, your vehicle
will go 1
mph
(1.6
km/h) faster.
