■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. (
P. 3 2 7 )
The engine oil may need to be replaced earlier depending on driving conditions.
●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.

■Using the “Lap Timer”
●When the “Lap Timer” function is turned “OFF” or the engine is stopped while a
lap is being timed, the lap timer will stop and the lap time up to that point will be
recorded.
●If the lap time being recorded ends with the same time as the fastest lap, the
newer time will be saved as the fastest lap time.
●If the lap time exceeds “9:59:59.99”, the display will return to “0:00:00.00” but
the total time will be recorded.
●If a warning message is displayed when a lap time is being measured, the lap
time will still continue to be recorded.
Operating the control pad while the warning message is shown returns the dis-
play to the stopwatch but the warning message will continue to appear until the
warning is resolved.
●In the normal display, the current measurement time and the latest lap time will
be displayed.
■Changing the temperature measurement unit
When the “Temp” measurement unit is ch anged, the air conditioning system tem-
perature setting, air outlet s and fan speed characteristic s may be changed. This is
normal and does not indicate a malfunction.
■If the battery is disconnected or discharges
“Lap Timer” data and “Clock” settings will be reset.

CAUTION
■When using the rear view monitor system
Observe the following precautions to avoid an accident that could result in death or
serious injuries:
●Never depend solely on the monitor system when reversing.
●Always check visually and with the mirrors to confirm your intended path is clear.
●Depicted distances between objects and flat surfaces differ from actual dis-
tances.
■Conditions which may affect the rear view monitor system
●If the back of the vehicle has been hit, the camera’s position and mounting angle
may have changed. Have the vehicle inspected by your Lexus dealer.
●Rapid temperature changes, such as when hot water is poured on the vehicle in
cold weather, may cause the system to function abnormally.
●If the camera lens is dirty, it cannot transmit a clear image. Rinse with water and
wipe with a soft cloth. If the camera lens is extremely dirty, wash with a mild
cleanser and rinse.
●The displayed image may be darker and mo ving images may be slightly distorted
when the system is cold.
NOTICE
■Camera precautions
●As the camera has a water proof constr uction, do not detach, disassemble or
modify it. This may cause incorrect operation.
●Do not allow organic solvent, car wax, window cleaner or glass coat to adhere to
the camera. If this happens, wipe it off as soon as possible.
●If a power washer is used for washing the vehicle, do not point it at or near the
camera as doing so may damage the camera.
●Do not use too much force when cleaning the camera lens.
