Cadillac cts User Manual

There are two ways to go to a higher speed:
D Use the accelerator pedal to get to the higher speed.

Press either the plus or minus button, then release the
button and the accelerator pedal. You will now cruise
at the higher speed.

D Press the resume/accelerate button. Hold it there

until you get up to the speed that you want, and then
release the button. To increase your speed in very
small amounts, briefly press the resume/accelerate
button and then release it. Each time you do 
this, your vehicle will speed up approximately 
1 mph (1.6 km/h).

The accelerate feature will only work after you have 
set the cruise control speed by pressing one of the 
set buttons.

There are two ways to reduce your speed while using
cruise control:
D Press the coast/decelerate button until you reach the

lower speed you want, then release it.

D To slow down in very small amounts, push the

coast/decelerate button briefly. Each time you 
do this, the vehicle will slow down approximately
1 mph (1.6 km/h).

Use the accelerator pedal to increase your speed. When
you take your foot off the pedal, your vehicle will slow
down to the cruise control speed you set earlier.
