NORMAL CONTROL Initial Stage When ignition switch is "ON", system initialization will be performed for approx. 3 seconds. During this time, warning lamp will stay ON and damping force will be switched to Hard status. After 3 seconds, warning lamp will turn off and normal control status will be restored. Normal Damping Force Control Establishment Damping force will have Soft Medium Hard status in AUTO mode and Medium Hard status in SPORT mode.
When double control items are satisfied at the same time it will be Hard Medium Soft in order.
Normal Damping Force Control Release Control mode release will be "Hard Medium Soft"or "Medium Soft". In case that returned from Hard status to
Medium status during control, it will be done after elapse of setting times. Returning from Medium status to Soft status
will be done immediately without delay.

Construction LCRV consists of sensing part and hydraulic control part.
1. Sensing PartIt detects the changes of vehicle height caused by vehicle load. It consists of load sensing spring and control leverwhich change according to vehicle load.
2. Hydraulic Control Part It consists of valve stem devices which controls hydraulicpressure according to load detected by sensing part.
