Speed Control without erasing the set speed memory.
Pressing the ON/OFF button or turning the ignition
switch OFF erases the set speed memory.
To Resume Speed
To resume a previously set speed, push the RESUME
ACCEL lever up and release. Resume can be used at any
speed above 20 mph (32 km/h) for 3.7L, 4.7L, and 5.7L
engines, and 14 mph (23 km/h) for 3.0L diesel engines.
To Vary The Speed Setting
When the Electronic Speed Control is on, speed can be
increased by pushing up and holding RESUME ACCEL.
Release the lever when the desired speed is reached, and
the new speed will be set.
Tapping RESUME ACCEL once will result in a 1 mph
(2 km/h) (3.7L, 4.7L, 5.7L, and 3.0L diesel engines) 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) (3.7L, 4.7L, 5.7L, and 3.0L diesel en-
gines).
To decrease speed while Electronic Speed Control is on,
push down and hold SET DECEL. Release the lever when
the desired speed is reached, and the new speed will be
set.
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.
NOTE: The Electronic Speed Control system has been
designed to shut down if multiple speed control switch
functions are operated simultaneously in order to ensure
proper operation. If this occurs, the system can be
reactivated by pushing the Electronic Speed Control
switch ON/OFF button and resetting the desired vehicle
SET speed.
