Vehicle status information and indicators
■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 part of the LTA (Lane
Tracing Assist) system or LDA (Lane
Departure Alert with steering control)
system. The display is enabled when
the operating conditions of the vehicle
sway warning are met. ( P.221, 230)
■Display off
A blank screen is displayed.
■Tire inflation pressure
●It may take a few minutes to display the
tire inflation pressure after the power
switch is turned to ON mode. It may also
take a few minutes to display the tire infla-
tion pressure after inflation pressure has
been adjusted.
●“--” may be displayed if the tire informa-
tion cannot be determined due to unfa-
vorable radio wave conditions.
●Tire inflation pressure changes with tem-
perature. The displayed values may also
be different from the values measured
using a tire pressure gauge.

WARNING
■Lexus Safety System+ 2.0
The Lexus Safety System+ 2.0 is
designed to operate under the assump-
tion that the driver will drive safely, and is
designed to help reduce the impact to
the occupants and the vehicle in the case
of a collision or assist the driver in normal
driving conditions.
As there is a limit to the degree of recog-
nition accuracy and control performance
that this system can provide, do not
overly rely on this system. The driver is
always responsible for paying attention
to the vehicle’s surroundings and driving
safely.

*:If equipped
LTA (Lane Tracing Assist)*
When driving on highways and
freeways with white (yellow) lane
lines, this function alerts the driver
when the vehicle might depart
from its lane or course
* and pro-
vides assistance by operating the
steering wheel to keep the vehicle
in its lane or course
*. Furthermore,
the system provides steering assis-
tance when dynamic radar cruise
control with full-speed range is
operating to keep the vehicle in its
lane.
The LTA system recognizes white
(yellow) lane lines or a course
*
using the front camera. Addition-
ally, it detects preceding vehicles
using the front camera and radar.
*: Boundary between asphalt and the side of the road, such as grass, soil, or
a curb
WARNING
■Before using LTA system
●Do not rely solely upon the LTA sys-
tem. The LTA system does not auto-
matically drive the vehicle or reduce
the amount of attention that must be
paid to the area in front of the vehicle.
The driver must always assume full
responsibility for driving safely by pay-
ing careful attention to the surround-
ing conditions and operating the
steering wheel to correct the path of
the vehicle. Also, the driver must take
adequate breaks when fatigued, such
as from driving for a long period of
time.
●Failure to perform appropriate driving
operations and pay careful attention
may lead to an accident, resulting in
death or serious injury.
●When not using the LTA system, use
the LTA switch to turn the system off.
■Situations unsuitable for LTA system
In the following situations, use the LTA
switch to turn the system off. Failure to do
so may lead to an accident, resulting in
death or serious injury.
●Vehicle is driven on a road surface
which is slippery due to rainy weather,
fallen snow, freezing, etc.
●Vehicle is driven on a snow-covered
road.
●White (yellow) lines are difficult to see
due to rain, snow, fog, dust, etc.
●Vehicle is driven in a temporary lane or
restricted lane due to construction
work.
●Vehicle is driven in a construction
zone.
●A spare tire, tire chains, etc. are
equipped.
●When the tires have been excessively
worn, or when the tire inflation pres-
sure is low.

■Lane departure alert function
When the system determines that the
vehicle might depart from its lane or
course
*, a warning is displayed on the
multi-information display, and either a
warning buzzer will sound or the steer-
ing wheel will vibrate to alert the driver.
When the warning buzzer sounds or the
steering wheel vibrates, check the area
around your vehicle and carefully operate
the steering wheel to move the vehicle
back to the center of the lane.
*: Boundary between asphalt and the side of the road, such as grass, soil, or a curb
■Steering assist function
When the system determines that the
vehicle might depart from its lane or
course
*, the system provides assis-
tance as necessary by operating the
steering wheel in small amounts for a
short period of time to keep the vehicle
in its lane.
If the system detects that the steering
wheel has not been operated for a fixed
amount of time or the steering wheel is not
being firmly gripped, a warning is displayed
on the multi-informat ion display and the
function is temporarily canceled.
*: Boundary between asphalt and the side of the road, such as grass, soil, or a curb
WARNING
●The vehicle is affected by wind from a
vehicle driven in a nearby lane.
●The vehicle has just changed lanes or
crossed an intersection.
●Tires which differ by structure, manu-
facturer, brand or tread pattern are
used.
●Snow tires, etc. are equipped.
●The vehicle is being driven at
extremely high speeds.
