Cruise Control
Important: For vehicles with Eaton VORAD Collision Warning System (CWS) with SmartCruise, see the “Collision Warning System” in General Information of this manual, before operating cruise control.
The cruise control is activated by the SPD CNTL (on/off) and RSM/ACC–SET/CST switches on the dash (see Fig.), or by optional PAUSE, RESUME, and SET buttons on the transmission shift knob (see Fig.). The minimum speed at which cruise control can be used is 30 mph (48 km/h). The minimum and maximum speed cruise control set limits can be programmed, by authorized personnel, into the engine electronics.

- To cruise at a particular speed:
- Press the upper half of the SPD CNTL (on/off) rocker switch on the instrument control panel.
- Hold the throttle down until the speedometer reaches the desired speed.
- Momentarily flip the RSM/ACC–SET/CST paddle switch on the instrument control panel down to SET/CST. or — Push the SET button on the transmission shift knob.
- To disengage the cruise control: Depress the brake pedal or clutch pedal. or — Press the lower half of the SPD CNTL rocker switch on the instrument control panel. or — Push the PAUSE button on the transmission shift knob.
- To resume a preselected cruise speed: Momentarily flip the RSM/ACC–SET/CST paddle switch on the instrument control panel to RSM/ACC. or — Push the RESUME button on the transmission shift knob. Cruise will return to the last speed selected. If the SPD CNTL rocker switch on the instrument control panel is off, turn it on.
- To adjust cruise speed up or down: Hold the paddle switch on the instrument control panel at RSM/ACC to accelerate, or at SET/CST to decelerate, until the desired speed is reached. or — Press the SET button on the transmission shift knob to accelerate, or the RESUME button to decelerate, until the desired speed is reached.
Warning: Do not use the cruise control system when driving conditions do not permit maintaining a constant speed, such as in heavy traffic or on roads that are winding, icy, snow-covered, slippery, or roads with a loose driving surface. Failure to follow this precaution could cause a collision or loss of vehicle control, possibly resulting in personal injury or property damage.
Notice: Do not attempt to shift gears without using the clutch pedal when the cruise control is engaged. Failure to follow this precaution will result in a temporarily uncontrolled increase in engine speed; transmission damage and gear stripping could result.
Note: The resume vehicle speed memory is not maintained if the ignition is shut off.
