Precaution for Hydraulic Body-Motion Control System
WARNING: This page is about a different car, the 2012 Infiniti QX56 and 2011 Infiniti QX56. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
- Always check the piping for loose connections, damage, or twists before starting operation, since pressure in hydraulic circuit becomes high during air bleeding operation.
- When repairing or replacing a malfunctioning part, always release pressure from hydraulic circuit, since dangerous conditions may be created when oil leakage occurs during air bleeding operation.
- Clean surrounding areas of oil inlet and air bleeder using steam before starting operation, since there may be mud on it.
- Always decrease pressure when removing a system related part, since system pressure is high.
- Seal the removed part using vinyl tape for preventing dirt from getting on or entering the removed part.
- Check system pressure again 1 day or more after bleeding operation is complete, since system pressure may decrease when air bleeding is insufficient.
- Use Genuine NISSAN Hydraulic Suspension Fluid for suspension fluid.
- Never reuse drained suspension fluid.
- Check for suspension fluid leakage after removing a system-related part.
