Jeep 2010 Liberty - Manual (Page 165)

To Vary the Speed Setting
When the Electronic Speed Control is set, you can in-
crease speed by pushing up and holding the RESUME
ACCEL lever. If the lever is continually held in the
RESUME ACCEL position, the set speed will continue to
increase until the lever is released, then the new set speed
will be established.
Tapping RESUME ACCEL once will result in a 1 mph
(2 km/h) speed increase. Each time the lever is tapped,
speed increases so that tapping the lever three times will
increase speed by 3 mph (5 km/h), etc.
To decrease speed while the Electronic Speed Control is
set, push down and hold the SET DECEL lever. If the
lever is continually held in the SET DECEL position, the
set speed will continue to decrease until the lever is
released. Release the lever when the desired speed is
reached, and the new set speed will be established.
Tapping the SET DECEL lever once will result in a 1 mph
(2 km/h) speed decrease. Each time the lever is tapped,
speed decreases.
To Accelerate for Passing
Press the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
