Cruise Control - Detroit Diesel DD15 EuroIV Operator's Manual

DD Platform EuroIV Operators Manual
Another throttle or governor characteristic you may need time to get used to is the
DDEC Limiting Speed Governor. This allows the driver to command total engine
response between idle and rated speed, such as accelerating at half throttle - an
advantage when driving under slippery conditions.
If you require wide-open throttle engine response, either accelerating or just plain
pulling hard, the throttle AP will have to be held to the floor. To obtain 100%
fueling at any speed, the AP will have to be maintained at the fully pressed
position.

Cruise Control

For added driver convenience and comfort, DDEC also features a Cruise Control
option that works just like the system in your car. It can be operated in any gear
above 1100 rpm or road speed faster than 20 mph (32 kph), up to the rated engine
speed. It also can be programmed to hold your road speed at or below the
maximum vehicle speed. The switch to energize Cruise Control is usually mounted
on the instrument panel or steering wheel.
Engine speed and power are varied under Cruise Control to maintain the set vehicle
speed. The vehicle speed must be above Min Cruise Set Speed and below Max
Cruise Set Speed. It is recommended that Max Cruise Set Speed be set to the
default to allow proper operation of other features such as Fuel Economy Incentive
and PasSmart. The Vehicle Speed Limit should be used to limit vehicle throttle
speed.
