2、2)自动控制： *当车子在行驶时，AIRmatic会依据车子负载及行驶速度自 动调整车高以增加行车的安全性及减少油耗。探当行驶速度约在140Km/hr(91mile)时，无论选择了何 种车身高度，车身都会降低到比正常高度再低15mm的高度。 探 当车速低于70Km/hr (45mi le)时，车身会回到正常高度。 探避震器软硬度调整(ADS)避震器软硬调整亦分为手动和自动两种:(1)可按上控制面板(UCP)上的避震器ADS按钮手动调 整软硬度，共有三种模式可供选择：探 标准模式(Comfort mode)避震器较软济 跑车模式1 (Sporty mode)避震器较硬探 跑车模式2 (Extre
