GMC 2006 Sierra - Manual (Page 190)

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.
