■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.

2-3. Operating the lights and windshield wipers
2
When driving
■The windshield wipers and wa sher can be operated when
The ignition switch is in the “ON” position.
■Effects of vehicle speed on wiper operation
The time until the drip prevention wiper sweep occurs is changed depending on
vehicle speed.
When low speed wiper operation is selected , wiper operation will be switched from
low speed to intermittent wiper operatio n only when the vehicle is stationary.
(However, when the intermittent wiper interv al adjuster is adjusted to the highest
level, the mode will not switch.)
■Wiper reverse motion
If snow or similar substances build up around the windshield and prevent the wiper
from moving smoothly, the wiper may reverse direction before the end of its stroke
in order to secure driver vi sibility and to protect the system. This is normal and does
not indicate a malfunction.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the wind-
shield washer fluid reservoir.
■Lifting the wiper
Activate the wiper and turn the ignition
switch to the “LOCK” position when the
wiper approaches the upper reverse position.
The wiper will stop moving.
Lift and hold the main and sub blades. The blades will not remain in the up posi-
tion if released.STEP1

Interior features
Rear window and outside rear view mirror defoggers
Defoggers are used to defog the rear window, and to remove raindrops, dew
and frost from the outside rear view mirrors.
On/off
The defoggers will automatically
turn off after 15 to 60 minutes. The
operation time changes according
to the ambient temperature and
vehicle speed.
■The defogger can be operated when
The ignition switch is in the “ON” position.
■The outside rear view mirror defoggers
Turning the rear window defogger on will turn the outside rear view mirror defog-
gers on.
CAUTION

Do not touch the outside surface of the re ar view mirror, as they can become very
hot and burn you.
