(g) Operation in cold weather The active height control suspension does not operate in cold weather when the suspension fluid temperature drops below -30_C (-22_F). In this case, operating the height select switch does not change the vehicle height. The vehicle height control enters the ready mode and the selected height control indicator light blinks. The active height control becomes operable if the engine is warmed up with the suspension fluid temperature being raised within normal operating limits. The vehicle changes to the selected height when the vehicle height control is in the ready mode. When the suspension fluid temperature is around -30_C (-22_F), the vehicle height cannot be raised even within the available load capacity. After warming up the engine, push the control switch on the "B" side once and then on the "Y" side to select the desired vehicle height. It takes longer to change the vehicle height when the suspension fluid temperature drops below -15_C (5_F).
