STARTING AND DRIVING "NORMAL" mode - For driving on roads with a normal surface. "HIGH" mode - For driving on rough roads which are unsurfaced or continually bumpy. The damping effect is set slightly firmer in "HIGH" mode. So you may feel the vibration of the vehicle compared to in "NORMAL" mode. However, this does not mean a malfunction in the system. We recommend you use a "NORMAL" mode in normal driving. To change the mode, push the selector switch. "NORMAL" mode The vehicle height remains at normal height at all driving speeds. "HIGH" mode The vehicle height switches between the following two vehicle heights according to the driving conditions: Vehicle height Normal High Driving condition Medium and high speed driving Low speed driving The indicator light shows "HIGH" mode is selected. When you turn the ignition key to the "ON" position, the indicator light will come on for 2 seconds in any mode. NOTICE For vehicles equipped with the height control switch, be sure to turn the ignition switch off before jacking. If this is not done, the vehicle height adjustment function will operate, which may cause body damage. (b) Malfunction warning If the "HI" indicator light blinks, there is a malfunction in this system. Have the system checked by your Lexus dealer at the first opportunity. 140
