5.
When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)
6.
Perform self-diagnosis check of all control units using CONSULT-III.
Precaution for Procedure without Cowl Top Cover
INFOID:0000000006256138
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for Hydraulic Body-Motion Control System
INFOID:0000000006255996
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.

DESCRIPTION
Description
INFOID:0000000006255998
• Hydraulic body-motion control system is adopted, which makes shock absorber stroke appropriately by
hydraulic pressure according to driving scenes.
• The adoption of this system allows the reduction in a roll angle (i.e. vehicle body tilt angle at cornering) to
improve steering stability and ride quality during travel on level roads. Furthermore, the use of this system
improves the running performance on rough roads by shock absorption and quality tire adhesion through
maximized stroke.
