Vehicle status information and indicators
Acceleration G-force on the vehi-
cle
Current G-force value (analyzed
value of front/rear and left/right
G-forces)
Record of the maximum G-forces
This display is intended for use as a
guideline. Depending on factors such
as the road surface condition, tem-
perature and vehicle speed, the display
may not show the actual condition of
the vehicle.
 Resetting the record of maximum
G-forces
Press and hold 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.
*: For F SPORT models, this item is not available when the ma in meter is in the
center position.
■Tire pressure
 P.260
■Vehicle sway warning*
Detects the sway of the vehicle within a
lane, which is often associated with a
decrease in the driver’s attention level, and displays the decrease in attention
using a bar display.
The shorter the bar length, the more
the driver may need to rest.
This display is a pa
rt of the LDA (Lane
Departure Alert with steering control) sys-
tem.The display is en abled when the oper-
ating conditions of the vehicle sway
warning are met. ( P.164)
*: For F SPORT models, this item is not
available when the main meter is in the
center position.
■Gear positions
Displays the current gear position
when the shift lever is in D or M.
■Units (if equipped) *
The units of measure used can be
changed while driving.
Unlike the units sett ing performed on ,
the units setting performed on can be
changed while driving.
*: For F SPORT models, this item is not available when the main meter is in the
right-side position.
■Blank (No items)
Displays no drive information contents.
■Tire pressure
●It may take a few minutes to display the
tire inflation pressu re after the engine
switch is turned to IGNITION ON mode.
It may also take a few minutes to display
the tire inflation pressure after inflation
pressure has b een adjusted.
●“---” may be displayed if the tire position
information cannot be determined due to
unfavorable radio wave conditions.
●Tire inflation pressure changes with tem-
perature. The displaye d values may also
be different from the values measured

1624-5. Using the driving support systems
• The vehicle is wobbling.
• The vehicle is being driven at extremely high speeds.
• When driving on a hill
• If the radar sensor or camera sensor is misaligned
●In some situations such as the following,
sufficient braking force may not be
obtained, preventing the system from
performing properly:
• If the braking functions cannot operate to
their full extent, such as when the brake
parts are extremely cold, extremely hot,
or wet
• If the vehicle is not properly maintained (brakes or tires are excessively worn,
improper tire inflation pressure, etc.)
• When the vehicle is being driven on a gravel road or other slippery surface
●Some pedestrians such as the following
may not be detected by the radar sensor
and camera sensor, preventing the sys-
tem from operating properly:
• Pedestrians shorter than approximately 3.2 ft. (1 m) or tall er than approximately
6.5 ft. (2 m)
• Pedestrians wearing oversized clothing (a rain coat, long skir t, etc.), making their
silhouette obscure
• Pedestrians who are carrying large bag- gage, holding an umbrella, etc., hiding
part of their body
• Pedestrians who are bending forward or squatting
• Pedestrians who are pushing a stroller, wheelchair, bicycle or other vehicle
• Groups of pedestrians which are close
together
• Pedestrians who are wearing white and look extremely bright
• Pedestrians in the dark, such as at night or while in a tunnel
• Pedestrians whose clothing appears to
be nearly the same co lor or brightness as
their surroundings
• Pedestrians near walls , fences, guardrails,
or large objects
• Pedestrians who are on a metal object (manhole cover, steel plate, etc.) on the
road
• Pedestrians who are walking fast
• Pedestrians who are changing speed abruptly • Pedestrians running out from behind a
vehicle or a large object
• Pedestrians who are extremely close to
the side of the vehicle (outside rear view
mirror, etc.)
■If VSC is disabled
●If VSC is disabled ( P.194), the pre-col-
lision brake assist and pre-collision brak-
ing functions are also disabled.
●The PCS warning light will turn on and
“VSC Turned Off Pre-Collision Brake
System Unavailable” will be displayed on
the multi-information display.

Driving
input over an extended period of time. The
steering wheel may feel heavy as a result.
Should this occur, refrain from excessive
steering input or stop the vehicle and turn
the engine off. The EPS system should
return to normal within 10 minutes.
WARNING
■The ABS does not operate effectively
when
●The limits of tire gripping performance
have been exceeded (such as exces-
sively worn tires on a snow covered
road).
●The vehicle hydroplanes while driving
at high speed on wet or slick roads.
■Stopping distance when the ABS is
operating may exceed that of normal
conditions
The ABS is not designed to shorten the
vehicle’s stopping di stance. Always main-
tain a safe distance from the vehicle in
front of you, especially in the following
situations:
●When driving on dirt, gravel or
snow-covered roads
●When driving with tire chains
●When driving over bumps in the road
●When driving over roads with potholes
or uneven surfaces
■TRAC may not operate effectively
when
Directional control and power may not
be achievable while driving on slippery
road surfaces, even if the TRAC system is
operating. Drive the vehicle carefully in
conditions where stability and power
may be lost.
■Hill-start assist control does not oper-
ate effectively when
●Do not overly rely on hill-start assist
control. Hill-start assist control may
not operate effectively on steep
inclines and roads covered with ice.
●Unlike the parking brake, hill-start
assist control is not intended to hold
the vehicle stationary for an extended
period of time. Do not attempt to use
hill-start assist control to hold the vehi-
cle on an incline, as doing so may lead
to an accident.
■When the VSC is activated
The slip indicator light flashes. Always
drive carefully. Reckless driving may
cause an accident. Exercise particular
care when the indicator light flashes.
■When the TRAC/VSC systems are
turned off
Be especially careful and drive at a speed
appropriate to the road conditions. As
these are the systems to help ensure
vehicle stability and driving force, do not
turn the TRAC/VSC systems off unless
necessary.
■Replacing tires
Make sure that all ti res are of the speci-
fied size, brand, tread pattern and total
load capacity. In addition, make sure that
the tires are inflated to the recom-
mended tire inflation pressure level.
The ABS, TRAC and VSC systems will
not function correctly if different tires are
installed on the vehicle.
Contact your Lexus dealer for further
information when replacing tires or
wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or
modifying the suspensi on will affect the
driving assist systems, and may cause a
system to malfunction.
