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 briefly from on to
resume/accelerate.
You'll go right back up to your chosen speed and
stay there.
If you 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.
Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
•
Use the accelerator pedal to get to the higher
speed. Press the set button at the end of the lever,
then release the button and the accelerator
pedal. You'll now cruise at the higher speed. If the
accelerator pedal is held longer than 60 seconds,
cruise control will turn off.
•
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.
To increase your speed in very small amounts,
move the switch briefly to resume/accelerate. Each
time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.
