2、2)自動控制： *當車子在行駛時，AIRmatic會依據車子負載及行駛速度自 動調整車高以增加行車的安全性及減少油耗。探當行駛速度約在140Km/hr(91mile)時，無論選擇了何 種車身高度，車身都會降低到比正常高度再低15mm的高度。 探 當車速低于70Km/hr (45mi le)時，車身會回到正常高度。 探避震器軟硬度調整(ADS)避震器軟硬調整亦分為手動和自動兩種:(1)可按上控制面板(UCP)上的避震器ADS按鈕手動調 整軟硬度，共有三種模式可供選擇：探 標準模式(Comfort mode)避震器較軟濟 跑車模式1 (Sporty mode)避震器較硬探 跑車模式2 (Extre
