Vehicle status information and indicators
*4: This distance is computed based on your average fuel consumption. As a
result, the actual distance that can be
driven may differ from that displayed.
■Energy monitor
 P.99
■AWD Control
Displays the driving force applied to
each wheel using segments.
The greater the number of segments
displayed, the greater the driving force
applied.
■G-force (if equipped)
Displays lateral G-forces on the vehi-
cle. Also displays, around the periph-
ery of the G-force display, the left and
right steering amount, accelerator
pedal input, and brake fluid pressure.

This display is intended for use as a guide- line. Depending on fact
ors such as the road
surface condition, temperature and vehicle
speed, the display may not show the actual
condition of the vehicle.
 Resetting the record of maximum
G-forces
Press and hold of the meter control
switch to reset the record.
Peak hold function
If lateral G-forces of 0.5 G or greater are
generated, the G-forc e value display will
turn amber and be held for 2 seconds.
■Tire pressure
 P.376
■Units (if equipped)
The units of measure used can be
changed while driving.
Unlike the units setting performed on the
settings display, th e units setting per-
formed on the drive information display
can be changed while driving.
■Blank (No items)
Displays no drive information contents.
■G-force display (if equipped)
●The G-force values may not be zero even
when the vehicle is parked, such as when
it is parked on an incline.
●Depending on the vehicle usage condi-
tions, the brake fluid pressure display may
not reach its maximum reading even
though the brake pedal is fully depressed.
●If a 12-volt battery terminal is discon-
nected and reconnect ed, the steering
amount display may be disabled tempo-
rarily. After driving th e vehicle for a while,
the display will be enabled.

Maintenance and care
When position of each tire is determined,
the inflation pressure of each tire will be
displayed on the multi-information display.
If tire inflation pressure becomes low
before the inflation pr essure is displayed,
the tire pressure warning light will come
on.
Depending on the vehicle and driving con-
ditions, initialization may take up to
approximately 1 hour to complete.
■Initializing the tire pressure warning sys-
tem
Initialize the system with the tire inflation
pressure adjusted to the specified level.
■If you press the tire pressure warning
reset switch accidentally
If initialization is perf ormed, adjust the tire
inflation pressure to the specified level and
initialize the tire pressure warning system
again.
■Initialization procedure
●Make sure to carry out initialization after
adjusting the tire inflation pressure.
Also, make sure the tires are cold before
carrying out initializat ion or tire inflation
pressure adjustment.
●If you have accidentally turned the power
switch off during initialization, it is not
necessary to press the reset switch again
as initialization will restart automatically
when the power switch has been turned
to ON mode for the next time.
●If you accidentally press the reset switch
when initialization is not necessary, adjust
the tire inflation pres sure to the specified
level when the tires are cold, and conduct
initialization again.
●While the position of each tire is being
determined and the inflation pressures
are not being displayed on the
multi-information display, if the inflation
pressure of a tire drops, the tire pressure
warning light will come on.
■When initialization of the tire pressure
warning system has failed
Initialization may take lo nger to complete if
the vehicle is driven on an unpaved road. When performing initialization, drive on a
paved road if possible. Depending on the
driving environment and condition of the
tires, initialization
will be completed in
approximately 10 to 30 minutes. If initializa-
tion is not complete after driving approxi-
mately 10 to 30 minutes, continue driving
for a while.
If the inflation pressure of each tire is not
displayed after driving for approximately 1
hour, perform the following procedure.
●Park the vehicle in a safe place for
approximately 20 minutes. Then drive
straight (with occasional left and right
turns) at approximately 25 mph (40
km/h) or more for approximately 10 to
30 minutes.
However, in the following situations, the tire
inflation pressure will not be recorded and
the system will not operate properly. Per-
form initialization again.
●When operating the tire pressure warn-
ing reset switch, the tire pressure warning
light does not blink 3 times.
●After performing initialization, the tire
pressure warning light blinks for 1 minute
then stays on while driving.
If the inflation pressure of each tire is still not
displayed, have the vehicle inspected by
your Lexus dealer.
The tire pressure warning valve and
transmitter is equipped with a unique
ID code. When replacing a tire pres-
sure warning valve and transmitter, it is
WARNING
■When initializing the tire pressure
warning system
Do not initializing tire inflation pressure
without first adjusting the tire inflation
pressure to the spec ified level. Other-
wise, the tire pressu re warning light may
not come on even if the tire inflation pres-
sure is low, or it may come on when the
tire inflation pressure is actually normal.
