1824-5. Using the driving support systems
The LDA system warns the
driver if the vehicle may deviate
from the current lane or course
*,
and also can slightly operate the
steering wheel to help avoid
deviation from the lane or
course
*.
The front camera is used to
detect lane lines or a course
*.
*: Boundary between the asphalt and grass, soil, etc., or structures,
such as a curb, guardrail, etc.
■Lane departure alert func-
tion
When the system determines
that the vehicle might depart
from its lane or course
*, a warn-
ing is displayed on a display,
and either a warning buzzer will
sound or the steering wheel will
vibrate to alert the driver.
Check the area around your vehicle
and carefully operate the steering
wheel to move the vehicle back to
the center of the lane or course
*.
Vehicles with BSM: If the system
determines that the vehicle may
collide with a vehicle in an adjacent
lane, the lane de parture alert will
operate even if the turn signals are
operating.
*: Boundary between the asphalt and grass, soil, etc., or structures, such as a curb,
guardrail, etc.
■Lane departure prevention
function
If the system determines that
the vehicle is likely to depart
from its lane or course
*, it pro-
vides assistance through steer-
ing wheel operations to help
avoid deviation from the lane or
course.
If the system determines that the
steering wheel has not been oper-
ated for a certain amount of time or
the steering wheel is not being
firmly gripped, a warning message
may be displayed and a warning
buzzer may sound to alert the
driver.
Vehicles with BSM: If the system
determines that the vehicle may
collide with a vehicl e in an adjacent
lane, the lane departure prevention
function will operate even if the turn

Driving
Constant speed cruising:
When there are no vehicles ahead
The vehicle drives at the speed set by the driver.
If the set vehicle speed is exceeded while driving down a hill, the set vehicle
speed display will blin k and a buzzer will sound.
Deceleration and follow-up cruising
When a preceding vehicle driving slower than the set vehicle
speed is detected
When a vehicle is detected driving ahead of your vehicle, the v ehicle auto-
matically decelerates and if a greater reduction in vehicle spe ed is neces-
sary, the brakes are applied (the stop lights will come on at t his time). The
vehicle is controlled to maintai n the vehicle-to-vehicle distance set by the
driver, in accordance with changes in the speed of the precedin g vehicle. If
vehicle deceleration is not sufficient and the vehicle approaches the vehicle
ahead, the approach wa rning will sound.
Acceleration
When there are no longer any preceding vehicles driving slower
than the set vehicle speed
The vehicle accelerates until th e set vehicle speed is reached and then
resumes constant speed cruising.
Starting off:
If a preceding vehicle stops, the vehicle will also stop (contr olled
stop). After the preceding vehicle starts off, pressing the “RES”
switch or depressing the accelerator pedal will resume follow-u p
cruising (start off operation). If a start off operation is not per-

Driving
Through control state “warning
phase 1” and “warning phase 2”,
the system determines if the
driver is aware and responsive
while outputting a warning and
controlling the vehicle speed. If
the system determines the
driver is not responsive, it will
operate in control state “deceler-
ation stop phase” and “stop hold
phase” and decelerate and stop
the vehicle. It will then operate
continuously in “stop hold
phase”.
■Operating conditions
This system opera tes when all of
the following cond itions are met:
●When the LTA is on
●When the vehicle speed is
approximately 30 mph (50 km/h)
or more
■Operation cancelation condi-
tions
In the following si tuations, system
operation will be canceled:
●When LTA control has been can-
celed (the LTA switch has been
pressed, etc.)
●When the dynamic radar cruise
control has been canceled
●When driver operations are
detected (the steering wheel is
held, the brake pedal, accelerator
pedal, parking brake, hazard light
switch, or turn sig nal lever is oper-
ated)
●When the driving assist switch is
pressed while in the stop and hold
phase
●When the engine switch has been
turned from ON to off
●Situations in whic h some or all of
the functions of the system cannot operate:
P. 1 6 6
■LTA control when operation is
canceled
When emergency driving stop sys-
tem operation is canceled, LTA con-
trol may also be canceled.
If driving operations are not
detected after the hands off
steering wheel warning oper-
ates, a buzzer will sound inter-
mittently and a message will be
displayed to warn the driver, and
the system will judge if the driver
is responsive or not. If driving
operations, such as holding the
steering wheel, are not per-
formed within a certain amount
of time, the system will enter
warning phase 2.
After entering warning phase 2,
a buzzer will sound in short
intervals and a message will be
displayed to warn the driver, and
the vehicle will slowly deceler-
ate. If driving operations, such
as holding the steering wheel,
are not performed within a cer-
tain amount of time, the system
will determine that the driver is
not responsive and enter the
deceleration stop phase.
The audio system will be muted
until the driver becomes respon-
sive.

After entering the deceleration
stop phase, a buzzer will sound
continuously and a message will
be displayed to warn the driver,
and the vehicle will slowly decel-
erate and stop. After the vehicle
stops, the system will enter the
stop and hold phase.
After the vehicle is stopped, the
parking brake will be applied
automatically. After entering the
stop and hold phase, the buzzer
will continue sounding continu-
ously and the emergency flash-
ers (hazard lights) will flash to
warn other drivers of the emer-
gency.

RSA (Road Sign
Assist)*
The RSA system detects
specific road signs using
the front camera and/or nav-
igation system (when speed
limit information is avail-
able) and warns the driver
via displays and buzzers.
WARNING
■For safe use
●Driving safely is solely the
responsibility of the driver. Pay
careful attent ion to the sur-
rounding conditions in order to
ensure safe driving.
●Do not rely so lely upon the
RSA. The RSA assists the
driver by providing road sign
information, but it is not a
replacement for the driver’s own
vision and awareness. Driving
safely is solely the responsibility
of the driver. Pay careful atten-
tion to the surrounding condi-
tions in order to ensure safe
driving.
■Situations in which the RSA
should not be used
●When it is necessary to disable
the system: P.161

tem may not ope rate properly

BSM (Blind Spot Moni-
tor)*
The Blind Spot Monitor is a
system that uses rear side
radar sensors installed on
the inner side of the rear
bumper on the left and right
side to assist the driver in
confirming safety when
changing lanes.
WARNING
■Cautions regarding the use of
the system
●The driver is solely responsible
for safe driving. Always drive
safely, taking care to observe
your surroundings.
●The Blind Spot Monitor is a sup-
plementary function which alerts
the driver that a vehicle is in a
blind spot of the outside rear
view mirrors or is approaching
rapidly from behind into a blind
spot. Do not overly rely on the
Blind Spot Monitor. As the func-
tion cannot judge if it is safe to
change lanes, over reliance
could lead to an accident result-
ing in death or serious injury. As
the system may not function
correctly under certain condi-
tions, the driver’s own visual
confirmation of safety is neces-
sary.

●Keep the sensors and the sur-
rounding areas on the rear
bumper clean at all times.
If a sensor or its surrounding area
on the rear bumper is dirty or cov-
ered with snow, the Blind Spot

stickers (including transparent
stickers), aluminum tape, etc. to
a sensor or its surrounding area
on the rear bumper.
●Do not subject a sensor or its
surrounding area on the rear
bumper to a strong impact.
If a sensor is moved even
slightly off position, the system
may malfunction and vehicles
may not be detected correctly.
In the following si tuations, have
your vehicle inspected by your
Toyota dealer.

• If the surrounding area of a sen- sor is scratched or dented, or
part of them h as become dis-
connected.
