NOTICE:
^ Be sure not to cover the connection part of the height control tube No. 7 when compressing and expanding the pneumatic shock absorber.
^ Do not touch the dust cover as much as possible in order not to deform it.
^ When disposing of the pneumatic shock absorber, see DISPOSAL.

INSTALLATION

1. INSTALL PNEUMATIC REAR LH W/SHOCK ABSORBER CYLINDER ASSEMBLY
a. Coat a new O-ring with MP grease, and install it to the pneumatic shock absorber.

HINT:
^ For disconnection and connection of the O-ring and tube, please refer to Suspension Control ( Automatic - Electronic Level ); Service Precautions. Suspension Control System
^ When replacing pneumatic cylinder assembly, it is unnecessary to replace the O-ring with a new one.

NOTICE: When the pneumatic shock absorber is not filled with air even after operating the compressor for move than 1 minute (height control indicator illumination blinks), re-start the engine and check if the compressor puts air into the pneumatic shock absorber.

5. ADJUST VEHICLE HEIGHT
6. ADJUST HEADLIGHT AIM ONLY

DISPOSAL

1. DISPOSE OF PNEUMATIC REAR LH W/SHOCK ABSORBER CYLINDER ASSEMBLY
a. Fully extend the shock absorber rod.
b. Using a drill, make a hole in the cylinder somewhere between A and B as shown in the illustration to discharge the gas inside.

CAUTION:
^ Be careful when drilling because shards of metal may fly about, so always use the proper safety equipment.
^ The gas is colorless, odorless and nonpoisonous.
