Here's the second way to go to a higher speed:
1. Move
the Cruise
switch from "ON"
to
"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 "Resume/Accelerate" for less than half
a
second and then release it. Each time you do this,
your vehicle will go about 1 mph (1.6 km/h) faster.
2. Push the button at the end of the lever, then release
the button and the accelerator pedal. You'll now
cruise at the higher speed.
The accelerate feature will only work after you have set
the Cruise Control speed by pushing the "SET" button.
