When driving
■Average vehicle speed
■ Driving range
Displays the average vehicle speed since
the engine was started or the function was
reset.
The function can be reset by pressing up or
down on the control pad for longer than
one second when the average vehicle
speed is displayed.
Displays the estimated maximum distance
that can be driven with the quantity of fuel
remaining.
This distance is computed based on your
average fuel consumption. As a result, the
actual distance that can be driven may dif-
fer from that displayed.
When only a small amou nt of fuel is added
to the tank, the display may not be updated.

■Engine coolant and engine oil temperature displays
In congested traffic, the engine coolant and engine oil displays may show a higher
than usual temperature. This is not a ma lfunction. If temperatures are abnormal,
these displays will flash.
To help protect the engine, the red zone of
the tachometer starts at different engine
speeds ranging from 4400 rpm to 9000
rpm depending on the engine coolant tem-
perature.

■“Oil Maintenance” (engine oil maintenance)
This system calculates engine oil replacement timing and reminds the
driver when it is time to replace th e oil. Resetting operation should be
performed at your Lexus dealer when you have them change the
engine oil. (This procedure cannot be performed while the vehicle is in
motion.)
Select “Oil Maintenance” and
press right on the control pad.
Press and hold right on the control
pad for 5 seconds.

■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.

4-3. Do-it-yourself maintenance
Add oil based on the oil level shown on the meter.
Do not add more than 0.5 qt. (0.5 L, 0.4 Imp. qt.) at a time regardless of
the oil level reading.
To check the oil level again, install the oil filler cap by turning it
clockwise.
Check the oil level using the “Oil Level” display and repeat the
above procedure if more oil is required.
Even if the measurement result shows that the oil is below the maximum
level, be careful not to add more oil than necessary.
Install the oil filler cap by turning it clockwise.
■Engine oil consumption
●The amount of engine oil consumed depe nds on the oil viscosity, the quality of
the oil and the way the vehicle is driven.
●More oil is consumed under driving conditions such as high speeds and fre-
quent acceleration and deceleration.
●A new engine consumes more oil.
●When judging the amount of oil consumpt ion, keep in mind that the oil may
have become diluted, making it difficult to judge the true level accurately.
●Oil consumption: Max. 1.1 qt./600 miles (0.9 Imp. qt./600 miles, 1.0 L/1000
km)
●If your vehicle consumes more than 1.1 qt. (1.0 L, 0.9 Imp. qt.) every 600 miles
(1000 km), contact your Lexus dealer.
■After the engine oil has been changed
The “Oil Maintenance” display on the mete r needs resetting. Have the display reset
at your Lexus dealer. ( P. 1 3 2 )

Indicates that engine oil
level is low. Check the level of engine
oil (
P. 132), and add if
necessary ( P. 2 5 7 ) .
Indicates that the engine
oil needs to be changed. Have the engine oil
