*2: Depending on the operating condi-
tion, the color and illuminating/flash-
ing state of the light change.
*3: The light comes on when the system
is turned off.
*4: Toyota parking assist-sensor OFF
indicator turns on when the power
switch is turned to ON while the
Toyota parking assist-sensor func-
tion is on. It will turn off after a few
seconds.
*5: These lights turn on when the power
switch is turned to ON to indicate
that a system check is being per-
formed. They will turn off after the
hybrid system is on, or after a few
seconds. There may be a malfunc-
tion in a system if the lights do not
turn on, or turn off. Have the vehicle
inspected by any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.

■Operational conditions
The pre-collision system is enabled and the system determines that the possibility of a frontal collision with a detected object is high.Each function is operational at the following speed
●Pre-collision warning
●Pre-collision brake assist
●Pre-collision braking
The system may not operate in the following situations:
●If a 12-volt battery terminal has been disconnected and reconnected and then the vehicle has not been driven for a certain amount of time
●If the shift lever is in R
●When the VSC OFF indicator is illuminated (only the pre-collision warning function will be operational)
■Object detection function
The system detects objects based on
their size, profile, motion, etc. However, an object may not be detected depend-
ing on the surrounding brightness and the motion, posture, and angle of the
detected object, preventing the system from operating properly. ( P.360)

which protrudes past its rear bumper
• If a vehicle ahead is irregularly
shaped, such as a tractor or side car
• If a vehicle ahead is a child sized bicy-
cle, a bicycle that is carrying a large
load, a bicycle ridden by more than
one person, or a uniquely shaped
bicycle (bicycle with a child seat, tan-
dem bicycle, etc.)
• If a pedestrian/or the riding height of a
bicyclist ahead is shorter than approx-
imately 1 m (3.2 ft.) or taller than
approximately 2 m (6.5 ft.)

oversized clothing (a rain coat, long
skirt, etc.), making their silhouette
obscure

squatting or bicyclist is bending for-
ward
• If a pedestrian/bicyclist is moving fast
• If a pedestrian is pushing a stroller,
wheelchair, bicycle or other vehicle
• When driving in inclement weather
such as heavy rain, fog, snow or a
sandstorm
• When driving through steam or smoke
• When the surrounding area is dim,
such as at dawn or dusk, or while at
night or in a tunnel, making a detect-
able object appear to be nearly the same color as its surroundings
• When driving in a place where the sur-
rounding brightness changes sud-
denly, such as at the entrance or exit
of a tunnel
• After the hybrid system has started
the vehicle has not been driven for a
certain amount of time
• While making a left/right turn and for a
few seconds after making a left/right
turn

lowered
• If the wheels are misaligned
• If a wiper blade is blocking the front
camera
• The vehicle is being driven at
extremely high speeds
• When driving on a hill
• If the radar sensor or front camera is
misaligned
●In some situations such as the follow-
ing, 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 main-
tained (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
■If VSC is disabled
●If VSC is disabled (P.439), the pre-
collision brake assist and pre-collision
braking functions are also disabled.

3625-5. Using the driving support systems
●The PCS warning light will turn on and
“VSC Turned OFF Pre-Collision Brake
System Unavailable” will be displayed
on the multi-information display.

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 provides assis-
tance by operating the steering
wheel to keep the vehicle in its
lane or course
*. Furthermore,
the system provides steering
assistance 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 cam-
era. Additionally, it detects pre-
ceding vehicles using the front
camera and radar.
*: Boundary between asphalt and the
side of the road, such as grass,
soil, or a curb

the vehicle departs from its lane, the
white line displayed on the side the
vehicle departs from flashes orange.
Inside of displayed lines is black
Indicates that the system is not able to

* or is temporarily canceled.
*: Boundary between asphalt and the

■Operation conditions of each func-
tion
●Lane departure alert function

following conditions are met.
• LTA is turned on.
• Vehicle speed is approximately 50
km/h (32 mph) or more.
*1
• System recognizes white (yellow) lane lines or a course

ate only for the recognized side.)
• Width of traffic lane is approximately 3
m (9.8 ft.) or more.
• Turn signal lever is not operated.
(Vehicles with BSM: Except when
another vehicle is in the lane on the

(P.371)
*1: The function operates even if the
vehicle speed is less than approxi-
mately 50 km/h (32 mph) when the
lane centering function is operating.
*2: Boundary between asphalt and the
side of the road, such as grass, soil,
or a curb
●Steering assist function
This function operates when all of the
following conditions are met in addition
to the operation conditions for the lane
departure alert function.
• Setting for “Steering Assist” in the
screen of the multi-information display
is set to “ON”. (P.179)
• Vehicle is not accelerated or deceler-
ated by a fixed amount or more.
• Steering wheel is not operated with a
steering force level suitable for chang-
ing lanes.
• ABS, VSC, TRC and PCS are not
operating.
• TRC or VSC is not turned off.
• Hands off steering wheel warning is
not displayed. (P.370)
●Vehicle sway warning function
This function operates when all of the
following conditions are met.

km/h (32 mph) or more.
• Width of traffic lane is approximately 3
m (9.8 ft.) or more.
• No system malfunctions are detected.
(P.371)
●Lane centering function
This function operates when all of the
following conditions are met.
• LTA is turned on.
• Setting for “Steering Assist” and “Lane
Center” in the screen of the multi-
information display are set to “ON”.
(P.179)
• This function recognizes white (yel-
low) lane lines or the position of a pre-
ceding vehicle (except when the
preceding vehicle is small, such as a
motorcycle).
• The dynamic radar cruise control with
full-speed range is operating in vehi-
cle-to-vehicle distance control mode.

■Temporary cancelation of functions
●When operation conditions are no lon-
ger met, a function may be temporar-
ily canceled. However, when the
operation conditions are met again,
operation of the function is automati-
cally restored. (P.369)
●If the operation conditions (P.369)
are no longer met while the lane cen-
tering function is operating, the steer-
ing wheel may vibrate and the buzzer
may sound to indicate that the func-
tion has been temporarily canceled.
However, if the “Alert” customization
setting is set to “Steering wheel vibra-
tion”, the system will notify the driver
by vibrating the steering wheel instead
of sounding the buzzer.
■Steering assist function/lane cen-
tering function
●Depending on the vehicle speed, lane
departure situation, road conditions,
etc., the driver may not feel the func-
tion is operating or the function may
not operate at all.
●The steering control of the function is
overridden by the driver’s steering
wheel operation.
●Do not attempt to test the operation of
the steering assist function.
■Lane departure alert function
●The warning buzzer may be difficult to
hear due to external noise, audio play-
back, etc. Also, it may be difficult to
feel steering wheel vibrations due to
the road conditions, etc.
●If the edge of the course* is not clear
or straight, the lane departure alert
function may not operate.
●Vehicles with BSM: It may not be pos-
sible for the system to determine if
there is a danger of a collision with a
vehicle in an adjacent lane.
●Do not attempt to test the operation of
the lane departure alert function.
*: Boundary between asphalt and the
side of the road, such as grass, soil,
or a curb
■Hands off steering wheel warning
In the following situations, a warning
message urging the driver to hold the
steering wheel and the symbol shown in
the illustration are displayed on the
multi-information display to warn the
