  3. Unlock the vehicle gateway for diagnostic communication. See Gateway (Unlock).
  4. On the vehicle touchscreen, touch Service Mode (spanner icon).
  5. Touch Chassis (damper icon) and then touch Suspension.
  6. Touch Service, and then touch Deflate All.
  7. Return to the procedure that required the air suspension system to be deflated.

Deflate One or More Dampers

  1. Raise and support the vehicle. See Raise Vehicle - 2 Post Lift.
  2. Connect a laptop with Toolbox 3 to the vehicle. See Toolbox 3 (Connect and Disconnect).
  3. Select the Actions/Autodiag tab, and then search for TAS service mode.
  4. Select PROC_TAS_X_ENTER-SERVICE-MODEvia Toolbox: (link), click Run, and then allow the routine to complete.
  5. Select the Actions/Autodiag tab, and then search for Deflate.
  6. Select the routine for the desired dampers:
    • PROC_TAS_X_DEFLATEvia Toolbox: (link)via Service Mode: Chassis ➜ Suspension ➜ Deflate - Deflates the front LH damper
    • PROC_TAS_X_DEFLATEvia Toolbox: (link)via Service Mode: Chassis ➜ Suspension ➜ Deflate - Deflates the front RH damper
    • PROC_TAS_X_DEFLATEvia Toolbox: (link)via Service Mode: Chassis ➜ Suspension ➜ Deflate - Deflates the rear LH damper
    • PROC_TAS_X_DEFLATEvia Toolbox: (link)via Service Mode: Chassis ➜ Suspension ➜ Deflate - Deflates the rear RH damper
    • PROC_TAS_X_DEFLATE-FRONT-AXLE - Deflates the front LH and RH dampers
    • PROC_TAS_X_DEFLATEvia Toolbox: (link)via Service Mode: Chassis ➜ Suspension ➜ Deflate - Deflates the rear LH and RH dampers
  7. Click Run, and then allow the routine to complete.
  8. Disconnect the laptop with Toolbox 3 from the vehicle. See Toolbox 3 (Connect and Disconnect).
  9. Return to the procedure that required the air suspension dampers to be deflated.

Deflate the Reservoir

  1. Raise and support the vehicle. See Raise Vehicle - 2 Post Lift.
  2. Connect a laptop with Toolbox 3 to the vehicle. See Toolbox 3 (Connect and Disconnect).
  3. Select the Actions/Autodiag tab, and then search for TAS service mode.
  4. Select PROC_TAS_X_ENTER-SERVICE-MODEvia Toolbox: (link), click Run, and then allow the routine to complete.
  5. Select the Actions/Autodiag tab, and then search for Deflate.
  6. Select PROC_TAS_X_DEFLATEvia Toolbox: (link)via Service Mode: Chassis ➜ Suspension ➜ Deflate, click Run, and then allow the routine to complete.
  7. Disconnect the laptop with Toolbox 3 from the vehicle. See Toolbox 3 (Connect and Disconnect).
  8. Return to the procedure that required the air suspension reservoir to be deflated.

Refill the Reservoir

  1. Remove the rear underhood apron. See Underhood Apron - Rear (Remove and Replace).
  2. Remove the underhood storage unit. See Underhood Storage Unit (Remove and Install).
  3. Remove the Schrader valve cap from the air suspension reservoir.
  4. Close the nitrogen tank valve, the pressure regulator valve, and the air line valve of the nitrogen tank kit.
  5. Connect the air line to the air suspension reservoir.
  6. Open the valve on the nitrogen tank, slowly open the regulator, and adjust the pressure to 18 Bar.
  7. Slowly open the valve on the nitrogen tank hose and allow the reservoir to fill.
    Informational PurposesAn informational icon, calling your attention
    Note
    The pressure on the regular will drop slightly, and rise as the reservoir fills.
  8. When the sound of air flow becomes silent and the regulator appears to hold steady, close the valve on the nitrogen tank, and monitor the pressure on the regulator.
  9. If the pressure on the regulator:
    • Holds steady - Close the valve on the air line, and then go to step 11.
    • Begins to drop - Close the valve on the air line, and then continue to the next step.
      Informational PurposesAn informational icon, calling your attention
      Note
      A leak has been detected.
  10. If the pressure on the regulator:
    • Continues to drop - There is a leak between the nitrogen tank valve and the air line valve. Go to step 11.
    • Stops and remains stable - There is a leak in the vehicle air suspension system. Investigate where.
  11. Close the pressure regulator valve to release the pressure in the air line.
  12. Disconnect the air line from the air suspension reservoir.
    Informational PurposesAn informational icon, calling your attention
    Note
    Remove the A/C adapter if installed previously.
  13. Install the Schrader valve cap onto the air suspension reservoir.
  14. Lower the vehicle. See .
  15. On the vehicle touchscreen, touch Service Mode (spanner icon).
  16. Touch Chassis (damper icon) and then touch Suspension.
  17. Touch Normal.
    Informational PurposesAn informational icon, calling your attention
    Note
    Any deflated dampers will automatically inflate
  18. Sit in the driver or front passenger seat, close all doors, and confirm that the vehicle moves appropriately as the suspension height is adjusted through the touchscreen.
  19. If another procedure required the air suspension reservoir to be refilled, return to that procedure, otherwise continue to the next step.
  20. Install the underhood storage unit. See Underhood Storage Unit (Remove and Install).
  21. Install the rear underhood apron. See Underhood Apron - Rear (Remove and Replace).
