Cruise Control

108SD d 10.03.000

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: When the cruise control is engaged, do not attempt to shift gears without using the clutch pedal. Failure to follow this precaution will result in a temporarily uncontrolled increase in engine speed. Transmission damage and gear stripping could result.

Cruise control is activated by two dash-mounted switches (see Fig.).

  • On/Off Switch—this two-position rocker is labeled SPD CNTL on the lower half of the switch. When cruise control is on, an amber light illuminates the top part of the switch.

  • Set/Resume Switch—this three-position paddle switch is labeled RES/ACC above the paddle and SET/CST below the paddle.

To turn cruise control on, press the upper half of the On/Off switch. To turn cruise control off, press the lower half of the On/Off switch.

To increase cruise speed, raise and hold the paddle of the Set/Resume switch to RES/ACC until the vehicle accelerates to the desired speed. To decrease cruise speed, lower and the paddle of the Set/Resume switch to SET/CST until the vehicle decelerates to the desired speed.

  1. To cruise at a particular speed:
    1. Press the upper half of the On/Off switch.
    2. Hold the accelerator pedal down until the speedometer reaches the desired speed.
    3. Momentarily lower the paddle of the Set/Resume switch to SET/CST.
  2. To disengage the cruise control:
    1. Depress the brake pedal (on an automatic or manual transmission) or
      Depress the clutch pedal (on a manual transmission only).
    2. Press the lower half of the On/Off switch.
  3. To resume a preselected cruise speed:
    1. Ensure the On/Off switch is on.
    2. Momentarily raise the paddle of the Set/Resume switch to RES/ACC. Cruise will return to the last speed selected.

    4. Note: When the vehicle speed drops below the minimum cruise control speed, cruise control will disengage. To resume to the preselected cruise speed, increase vehicle speed to above minimum cruise control speed and momentarily raise the paddled of the Set/Resume switch to RES/ACC.

    Note: The speed memory is lost whenever the ignition is turned off or the cruise control switch is toggled to Off.

  4. To increase cruise speed, raise and hold the paddle of the Set/Resume switch to RES/ACC until the vehicle accelerates to the desired speed.
  5. To decrease cruise speed, lower and the paddle of the Set/Resume switch to SET/CST until the vehicle decelerates to the desired speed.
