Suspension Control System: Precaution

  1. WHEN USING JACK OR LIFT 
    1. When work is performed under the vehicle or when jacking the vehicle up, make sure to turn the engine switch off.
    2. If the vehicle must be raised with its engine running, connect terminals 11 (OPA) and 4 (CG) of the DLC3 to stop the vehicle height control operation of the suspension control ECU.
  2. WHEN ADDING AIR 
    NOTE:
    • Only operate the height control compressor to add air for less than 3 minutes. In order to protect the height control compressor, if it is operated for 3 minutes continuously, its operation is prohibited for 10 minutes.
    • If the height control compressor is operated continuously, its operation is automatically stopped after 3 minutes and its operation is prohibited for 10 minutes to protect the height control compressor.
