Meter operation restrictions while vehicle is in motion
■
While the vehicle is in motion, some menu items cannot be changed using the con-
trol pad. Restricted items are displayed in gray or without an arrow. These items can
be operated once the vehicle is stopped.
"Rev Ind" (rev indicator)
■
Even if the green or amber indicator is set to 9000 rpm, the over-rev warning
●
will be displayed.
If the green and amber indicators are both set to the same engine speed, the
●
indicator will be shown in amber.
Measuring the engine oil level
■
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 mea-
surement results.
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.
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.
If the measurement result flashes, the measuring function is malfunctioning.
●
Have the vehicle inspected by your Lexus dealer.
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. (
The engine oil may need to be replaced earlier depending on driving conditions.
