  1. Backrest Tilt:Pull the handle out completely and lean back or forwards to adjust the backrest tilt. Release the handle when the correct position is achieved. The backrest has a 52 degree range of movement.
    When adjusted, the backrest inclination should allow the driver to reach the steering wheel with angled arms.

    Notice: Do not install seat covers on seats with heating and ventilation. Do not cover the seat with blankets, clothing, or pillows. Blocking the air flow through the cushions can cause the seat to overheat and damage the seat.

    Do not run the seat heating or ventilation when the seat is unoccupied.
    1. Heat/Ventilation:There are three heat or ventilation settings available as as shown, see Fig..Toggle the rear button to adjust the level of seat heating or ventilation.
      Heat:To turn on the heat, push the top of the forward switch as as shown, see Fig..The red light next to the switch illuminates.
      A sensor located in the seat controls the temperature and turns the heat off when the desired temperature is reached. Body size and clothing can affect how quickly the seat achieves the set temperature.
      Ventilation:To turn on the ventilation, push the bottom of the forward switch as as shown, see Fig.. The blue light next to the switch illuminates.
      Two fans draw cabin air into the seats to reduce perspiration. Ventilation should not be run continuously.
      To turn off the heat and ventilation, move the switch to the middle position.

      1. Ventilation On

      2. Heat/Ventilation Off

    2. Back and Side Support:There are three switches that control the back and side support areas of the seat. Making changes to a driver's sitting position from time to time helps prevent driver fatigue and improves posture.
      1. Lumbar (Lower) Back Support:Press the forward button to inflate the cushion highlighted in see Fig. to increase support at the lower back. This moves the driver's spine into a double S shape and decreases pressure on the spine.

      2. Upper Back Support:Press the central button to inflate the cushion highlighted in see Fig. to increase support at the mid-back region. This can help prevent the driver from sitting in a slouched, hunched, or hollow-back position.

      3. Side Support:
        Inflate the side bolster's as shown, see Fig. to help prevent driving in slouched position and from sliding across the backrest.

    3. Height Adjustment:Pull or push the handle to adjust the seat height.
      Adjust the seat so the driver's feet can move each pedal through its full range of motion without fully stretching out the driver's legs or using force.
    4. Damper Adjustment:Move the lever down to increase damping on rough roads, or up to decrease damping on flat roads.
      The damper protects the driver's spine by absorbing vertical vibrations and shocks. It should be adjusted down far enough that the driver's feet never lose contact with the pedals. In general, heavier drivers won't have to adjust the lever up.
    5. Fore/Aft Isolator:Rotate the isolator lever to the left to lock the isolator, or to the right to allow horizontal movement.
      Damping horizontal shocks can be helpful with driving off-road or pulling a tank trailer.
    6. Seat Extension:Pull the lever to move the seat cushion forwards or back. The cushion moves up to 2-3/8 inches (60 mm) in 3/8-inch (10-mm) increments. Releasing the lever locks the cushion in place.
      Adjust the length of the seat cushion until there is space for three fingers between the cushion's front edge and the back the driver's knee. This helps to help improve circulation in the lower legs.
    7. Fore/Aft Slide:Pull the lever to unlock the seat and slide it forward or back. Release the lever to lock the seat in position.
      Adjust the seat so that reaching and pressing the pedals requires no effort and all dashboard controls are within easy reach.
    8. Seat Tilt:Pull the lever and add or reduce weight on the front area of the seat cushion to move it into one of three positions. Release the lever to lock the seat into position.
      The tilt of the seat, along with the tilt of the backrest and the contour of the seat cushion, affects the amount of pressure placed on the underside of the thighs and the back.
    9. Armrest Tilt:To adjust the armrest angle, tilt the armrest to the highest position, then down to the lowest position, then to the desired position.
      The armrest should be at an angle where the elbows lay lightly on it; this helps to relax the muscles in the shoulder and neck.
