STARTING AND DRIVING Normal mode: Suitable for driving on roads with a normal surface. High mode: Suitable for driving on rough roads which are unsurfaced or continually bumpy. The damping effect is set slightly firmer in the high mode. So you may feel the vibration of the vehicle compared to in the 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 the high mode is selected. 31L336 CAUTION 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 an accident. Malfunction warning If the system is malfunctioning, "Height Hi" appears on the multi-information display, the master warning light comes on and a warning tone sounds. Although it is no problem to continue driving, have the system checked by your Lexus dealer at the first opportunity. 356
