Suspension: Service Precautions
Precautions^ When installing rubber parts, final tightening must be carried out under
unladen condition* with tires on ground.
^ Fuel, radiator coolant and engine oil full. Spare tire, jack, hand tools and mats in designated positions.
^ After installing removed suspension parts, check wheel alignment and adjust If necessary.
^ Use flare nut wrench when removing or installing brake tubes.
^ Always torque brake lines when installing.
SPECIAL CAUTIONS FOR FULL-ACTIVE SUSPENSION
^ Stopping the engine may cause the vehicle's height to change. Therefore, the following operations should not be performed for approximately 3 minutes after the engine has been stopped.
(1) Disconnecting battery cables
(2) Removing fuses
(3) Jacking up the vehicle
(4) Inserting your arm into the wheelhouse
^ Make the best use of CONSULT, the electronic diagnostic tester, during system checks or part replacement.
^ Control unit retains self-diagnostic results in memory. Before disconnecting battery terminals or fuse (No.17) check the self-diagnostic results. Failure to do this may clear important data.
^ Do not allow foreign matter to enter any part of active suspensions while removing or installing parts. Carefully observe the following instructions:
(1) Select an area that is clean and free from dust or dirt.
(2) Wash your hands and work with bare hands.
(3) Do not remove plugs (if so equipped) until parts are ready for immediate replacement.
^ Pipes are always filled with highly pressurized oil (regardless of ON-OFF engine operation). Be sure to relieve pressure before removing parts.
^ Do not get under vehicle or start engine when lifting vehicle with only a jack.
^ Lift vehicle with all wheels oft ground and place on rigid racks before working under vehicle.
^ Use only genuine "Fluid A-Active Suspension" in active suspension system.
^ Fill reservoir tank with specified amount of fluid. Do not overfill in the following cases, as this may cause fluid to overflow from reservoir tank:
(1) When oil pressure is relieved from hydraulic lines.
(2) Before using vehicle after an extended period of time.
^ Be extremely careful when opening multivalve unit bypass valves or pressure control unit. Doing so, may cause vehicle height to decrease abruptly.
^ Be extremely careful when loosening air vent bleeders on pressure control units and accumulators because of highly pressurized oil.
^ Before disposing of main accumulator, pressure control units or actuators, closely observe instructions on caution labels. Ensure to completely discharge nitrogen gas from accumulators. Each pressure control unit is equipped with a return accumulator and each actuator, with a sub-accumulator.
^ Before disposing of pump or pump accumulators, slowly loosen safety plugs to completely discharge nitrogen gas from accumulators. Each gas chamber is filled with oil. Place a cloth around safety plug to prevent oil from spouting out before loosening safety plug. Pump is equipped with a small accumulator.
