■Situations in which the system
may not operate properly
●In certain situations, such as the
following, a detectable object may
not be detected by the front sen-
sors, and the system may not
operate properly:
• When a detectable object is approaching your vehicle
• When your vehicle or a detectable object is wandering
• When a detectable object makes
an abrupt maneuver (such as sud-
den swerving, acceleration or
deceleration)
• When suddenly approaching a detectable object
• When the detectable object is
near a wall, fence, guardrail, man-
hole cover, steel plate on the road
surface, or another vehicle
• When there is a structure above a detectable object
• When part of a detectable object
is hidden by another object (large
luggage, umbrella, guardrail, etc.)
• When multiple det ectable objects
are overlapping
• When a bright light, such as the sun, is reflecting off of a detect-
able object
• When a detectable object is white and looks extremely bright
• When the color or brightness of a detectable object causes it to
blend in with its surroundings
• When a detectable object cuts in
front of or suddenly emerges in
front of your vehicle
• When approaching a vehicle
which is diagonal

• If a vehicle ahead is a child sized bicycle, is carrying a large load, is
carrying an extra passenger, or
has an unusual shape (bicycles
equipped with a child seat, tan-
dem bicycles, etc.)
• If a pedestrian or bicycle is shorter than approximately 3.2 ft. (1 m) or
taller than approximately 6.5 ft. (2
m).
• When the silhouette of a pedes- trian or bicycle is unclear (such as
when they are wearing a raincoat,
long skirt, etc.)
• When a pedestrian or bicycle is
bending forward or squatting
• When a pedestrian or bicycle is moving at high speed
• When a pedestrian is pushing a stroller, wheelchair, bicycle or
other vehicle
• When a detectable object blends in with the surrounding area, such

greatly from the direction traffic
flows in the oncoming lane
• When turning left/right and approaching a pedestrian which
was traveling in the same direc- tion as the vehicle and continues
straight
●In addition to the preceding, in
certain situations, such as the fol-
lowing, the emergency steering
assist may not operate properly:
• When a detectable object is too close to the vehicle
• When there is insufficient space to perform evasive steering maneu-
vers or an obstruction exists in the
evasion direction
• When there is an oncoming vehi- cle
The pre-collision system can
be enabled/disabled through
a customize setting. ( P.412)
The system is enabled each time
the engine switch is turned to ON.
When the system is disabled,
the PCS warning light will illu-
minate and a message will be
displayed on the multi-infor-
mation display.

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

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.

■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.

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 8 9
■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

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.

System componentsWARNING
■To ensure the system can
operate properly
Blind Spot Monitor sensors are
installed behind the left and right
sides of the rear bumper respec-
tively. Observe the following to
ensure the Blind Spot Monitor can
operate correctly.
●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
Monitor may not operate and a
warning message will be dis-
played. In this situation, clear off
the dirt or snow and drive the
vehicle with the operation condi-
tions of the BSM function
(
P.235) satisfied for approxi-
mately 10 minutes. If the warning
message does not disappear,
have the vehicle inspected by
your Toyota dealer.
●Do not attach a ccessories,
stickers (including transparent
stickers), aluminum tape, etc. to
a sensor or its surrounding area
on the rear bumper.
