Chrysler 2005 Crossfire - Manual (Page 90)

To Vary The Speed Setting
If a set speed needs to be adjusted slightly, lift up or hold
down the speed control lever briefly until the desired
speed is reached. A single tap on the lever up or down
will change the speed in 0.6 mph (1 km/h) increments.
When the lever is released, the newly set speed remains.
To increase the speed for passing, use the accelerator.
After the accelerator is released, the previously set speed
will resume automatically.
To Deactivate
A soft tap on the brake pedal, or normal brake pressure
while slowing the vehicle, will deactivate the speed
control without erasing the memory. Pushing the speed
control lever forward or turning the key in the ignition
switch to the OFF/LOCK position will turn off the speed
control and erase the memory.
