2-2. Instrument cluster n Meter operation restrictions while vehicle is in motion While the vehicle is in motion, some menu items cannot be changed using the control pad. Restricted items are displayed in gray or without an arrow. These items can be operated once the vehicle is stopped. n "Rev Ind" (rev indicator) l Over-rev warning (regular setting) If the engine speed enters the red zone, the over-rev warning will be shown in red regardless of the set speed. l Even if the green or amber indicator is set to 9000 rpm, the over-rev warning will be displayed. l If the green and amber indicators are both set to the same engine speed, the indicator will be shown in amber. n Measuring the engine oil level l The dry sump lubrication system circulates the engine oil between the engine and oil tank according to driving conditions. Accordingly, the engine oil level in the oil tank may vary even if the overall amount is constant, affecting the measurement results. l It takes some time for the engine oil level to stabilize after the engine is started. To obtain a more stable result, drive the vehicle for a while and then perform the measurement without stopping the engine. l If an attempt to measure the oil level is made immediately after the previous oil level measurement process was completed, the previous measurement may be displayed. l If the measurement result flashes, the measuring function is malfunctioning. Have the vehicle inspected by your Lexus dealer. n Engine oil maintenance "Oil maintenance required" will be displayed once the vehicle has been driven for more than 6214 miles (10000 km) since the last reset. (→P. 327) The engine oil may need to be replaced earlier depending on driving conditions. 156
