●In the following situations, if the situation has changed (or the vehicle has been
driven for some time) and the normal operating conditions are d etected, the mes- sage will disappear and the system will become operational.
If the message does not disappear, contact any authorized Toyot a retailer or Toyota
authorized repairer, or any reliable repairer.
• When the temperature around the radar sensor is outside of the operational range,
such as when the vehicle is in the sun or in an extremely cold environment • When the front camera cannot detect objects in front of the ve hicle, such as when driving in the dark, snow, or fog, or when bright lights are sh ining into the front
camera • Depending on the conditions in the vicinity of the vehicle, th e radar may judge the surrounding environment can not be properly recognized. In that case, “Pre-Colli-
sion System Unavailable See Owner’s Manual” is displayed.

*: If equipped
The system can detect the follow-
ing (The detectable objects differs
depending on the function.):
 Vehicles
 Bicyclists
 Pedestrians
■Pre-collision warning
When the system determines that
the possibility of a frontal collision is
high, a buzzer will sound and a
warning message will be displayed
on the multi-information display to
urge the driver to take evasive
action.
■Pre-collision brake assist
When the system determines that
the possibility of a frontal collision is
high, the system applies greater
braking force in relation to how
strongly the brake pedal is
depressed.
■Pre-collision braking
If the system determines that the
possibility of a frontal collision is
extremely high, the brakes are
automatically applied to help avoid
the collision or reduce the impact of
the collision.
■Emergency steering assist
If the system determines that the
possibility of a collision with a
pedestrian is high and that there is
sufficient space for the vehicle to be
PCS (Pre-Collision Sys-
tem)*
The pre-collision system uses
a radar sensor and front cam-
era to detect objects ( P.209)
in front of the vehicle. When
the system determines that the
possibility of a frontal collision
with an object is high, a warn-
ing operates to urge the driver
to take evasive action and the
potential brake pressure is
increased to he lp the driver
avoid the collision. If the sys-
tem determines that the possi-
bility of a frontal collision with
an object is extremely high, the
brakes are automatically
applied to help avoid the colli-
sion or help reduce the impact
of the collision.
The pre-collision system can be
disabled/enabled and the warn-
ing timing can be changed.

■When to disable the pre-colli- sion system
In the following situations, disable the system, as it may not operate prop-erly, possibly leading to an accident
resulting in death or serious injury:
●When the vehicle is being towed
●When your vehicle is towing another vehicle
●When transporting the vehicle via truck, boat, train or similar means of
transportation
●When the vehicle is raised on a lift
with the hybrid system on and the tires are allowed to rotate freely
●When inspecting the vehicle using a drum tester such as a chassis dynamometer or speedometer tes-
ter, or when using an on vehicle wheel balancer
●When a strong impact is applied to the front bumper or front grille, due to an accident or other reasons
●If the vehicle cannot be driven in a stable manner, such as when the
vehicle has been in an accident or is malfunctioning
●When the vehicle is driven in a sporty manner or off-road
●When the tires are not properly inflated
●When the tires are very worn
●When tires of a size other than
specified are installed
●When tire chains are installed
●When a compact spare tire or an emergency tire puncture repair kit is
used

steering wheel assist is operating, the
buzzer sounds and the driver is warned.
Each time the buzzer sounds, the con-
tinuing time of the buzzer becomes lon-
ger.
The buzzer also sounds even if the alert
type is set to steering wheel vibration.
■Vehicle sway warning function
When the system determines that the
vehicle is swaying while the vehicle sway warning function is operating, a buzzer sounds and a warning message
urging the driver to rest and the symbol shown in the illustration are simultane-ously displayed on the multi-information
display.
Depending on the vehicle and road con-
ditions, the warning may not operate.
■Warning message
If the following warning message is dis- played on the multi-information display
and the LTA indicator illuminates in orange, follow the appropriate trouble-shooting procedure. Also, if a different
warning message is displayed, follow the instructions displayed on the screen.
●“LTA Malfunction Visit Your Dealer”
The system may not be operating prop-
erly. Have the vehicle inspected by any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
●“LTA Unavailable”
The system is temporarily canceled due
to a malfunction in a sensor other than
the front camera. Turn the LTA system
off, wait for a little while, and then turn
the LTA system back on.
●“LTA Unavailable at Current Speed”
The function cannot be used as the
vehicle speed exceeds the LTA opera-
tion range. Drive slower.

WARNING
■Situations unsuitable for dynamic radar cruise control
with full-speed range
Do not use dynamic radar cruise con- trol with full-speed range in any of the
following situations. Doing so may result in inappropriate speed control and could cause an accident resulting
in death or serious injury.
●Roads where there are pedestrians,
cyclists, etc.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as those
covered with rain, ice or snow
●On steep downhills, or where there
are sudden changes between sharp up and down gradients
Vehicle speed may exceed the set
speed when driving down a steep hill.
●At entrances to freeways and high- ways
●When weather conditions are bad enough that they may prevent the
sensors from detecting correctly (fog, snow, sandstorm, heavy rain, etc.)
●When there is rain, snow, etc., on the front surface of the radar or
front camera
●In traffic conditions that require fre-
quent repeated acceleration and deceleration
●When your vehicle is towing a trailer (vehicles with towing pack-ages) or during emergency towing

ing on ramp way.
In the following situations, the RSA
system will notify the driver.
 When the vehicle speed exceeds
the speed notification threshold
of the speed limit sign displayed,
the sign display will be empha-
sized and a buzzer will sound.
 When the RSA system recog-
nizes a no-entry sign and detects
that the vehicle has entered a
no-entry area based on the map
information of the navigation sys-
tem, the no-entry sign flashes
and a buzzer will sound. (For
vehicles with 7-inch/8-inch dis-
play navigation system)
 If it is detected that your vehicle
is overtaking when a no overtak-
ing sign is displayed on the multi-
information display, the dis-
played sign will flash and a
buzzer will sound.
Depending on the situation, traffic
environment (traffic direction,
speed unit) may be detected incor-
rectly and a notification function
may not operate properly.

■Automatic turn-off of RSA sign dis-
play
One or more signs automatically turn off in the following situations.

●The road changes due to a left or right turn, etc.
■Conditions in which the function
may not operate or detect correctly
In the following situations, RSA does not operate normally and may not recognize
signs, display the incorrect sign, etc. However, this does not indicate a mal-function.
●The front camera is misaligned due to a strong impact being applied to the
sensor, etc.
●Dirt, snow, stickers, etc., are on the
windshield near the front camera.
●In inclement weather such as heavy
rain, fog, snow or sand storms.

sun, etc., enters the front camera.
●The sign is dirty, faded, tilted or bent.
●The contrast of electronic sign is low.
●All or part of the sign is hidden by the leaves of a tree, a pole, etc.
●The sign is only visible to the front camera for a short amount of time.

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, tak-
ing care to observe your surround- ings.
The Blind Spot Monitor is a supple-
mentary 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 function cannot judge if it is safe to change lanes, over reliance could lead to an
accident resulting in death or serious injury.
As the system may not function cor-
rectly under certain conditions, the driver’s own visual confirmation of safety is necessary.
