Driving
• When the temperature around the radar sensor is outside of the opera-
tional range, such as when the vehicle is in the sun or in an e xtremely cold
environment
• When the front camera cannot d etect objects in front of the vehicle, such
as when driving in the dark, sno w, or fog, or when bright lights are shining
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 recognize d. In that
case, “Pre-Collision System Unavailable See Owner’s Manual” is dis-
played.

The system can detect the fol-
lowing (The detectable objects
differs depending on the func-
tion.):
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.
“BRAKE!”
■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 colli-
sion is extremely high, the
brakes are automatically applied
to help avoid the collision or
reduce the impact of the colli-
sion.
PCS (Pre-Collision Sys-
tem)
The pre-collision system
uses a radar sensor and
front camera to detect
objects ( P.230) in front of
the vehicle. When the sys-
tem determines that the
possibility of a frontal colli-
sion with an object is high, a
warning operates to urge
the driver to take evasive
action and the potential
brake pressure is increased
to help the driver avoid the
collision. If the system
determines that the possi-
bility of a frontal collision
with an object is extremely
high, the brakes are auto-
matically applied to help
avoid the collision or help
reduce the impact of the col-
lision.
The pre-collision system can
be disabled/enabled and the
warning timing can be
changed. ( P.234)

■Situations in which the system
may not operate properly
●In some situations such as the fol-
lowing, an object may not be
detected by the radar sensor and
front camera, preventing the sys-
tem from operating properly:
• When a detectable object is approaching your vehicle
• When your vehicle or a detectable
object is wobbling
• If a detectable object makes an abrupt maneuver (such as sudden
swerving, accelera tion or deceler-
ation)
• When your vehicle approaches a
detectable object rapidly
• When a detectable object is not directly in front of your vehicle
• When a detectable object is near a wall, fence, guardrail, manhole
cover, vehicle, steel plate on the
road, etc.
• When a detectable object is under
a structure
• When part of a detectable object is hidden by an object, such as
large baggage, an umbrella, or
guardrail
• When there are many things
which can reflect the radio waves
of the radar in the vicinity (tunnels,
truss bridges, gravel roads, snow
covered road that have tracks,
etc.)
• When there is an effect on the radio waves to the radar that is
installed on another vehicle • When multiple det
ectable objects
are close together
• If the sun or other light is shining
directly on a detectable object
• When a detectable object is a shade of white and looks
extremely bright
• When a detectable object appears to be nearly the same color or
brightness as its surroundings
• If a detectable object cuts or sud- denly emerges in front of your
vehicle
• When the front of your vehicle is hit by water, snow, dust, etc.
• When a very bright light ahead, such as the sun or the headlights
of oncoming traffic, shines directly
into the front camera
• When approaching the side or front of a vehicle ahead
• If a vehicle ahead is a motorcycle
• If a vehicle ahead is narrow, such as a personal mobility vehicle
• If a preceding vehicle has a small rear end, such as an unloaded
truck

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 t unnel, making a
detectable object appear to be
nearly the same color as its sur-
roundings
• When driving in a place where the surrounding brightness changes
suddenly, 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

WARNING
■Before using dynamic radar
cruise control with full-speed
range
●Driving safely is the sole
responsibility of the driver. Do
not rely solely on the system,
and drive safely by always pay-
ing careful attent ion to your sur-
roundings.
●The dynamic radar cruise con-
trol with full-speed range pro-
vides driving assistance to
reduce the driver’s burden.
However, there are limitations to
the assistance provided.
Read the followin g conditions
carefully. Do not overly rely on
this system and always drive
carefully.

WARNING
●Assisting the driver to operate
the vehicle
The dynamic radar cruise control
with full-speed range does not
include function s which will pre-
vent or avoid collisions with vehi-
cles ahead of your vehicle.
Therefore, if there is ever any
possibility of da nger, the driver
must take immediate and direct
control of the vehicle and act
appropriately in order to ensure
the safety of all involved.
■Situations unsuitable for
dynamic radar cruise control
with full-speed range
Do not use dynamic radar cruise
control with full-speed range in
any of the following situations.
Doing so may result in inappropri-
ate speed control and could
cause an accident resulting in
death or serious injury.
●Roads where there are pedes-
trians, 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
highways
●When weather conditions are
bad enough that they may pre-
vent the sensors from detecting
correctly (fog, snow, sand-
storm, heavy rain, etc.)
●When there is rain, snow, etc.,
on the front surface of the radar
or front camera
●In traffic conditions that require
frequent repeated acceleration
and deceleration
●When your vehicles is towing a
trailer or another vehicle, except
when the followin g condition is
met.
• When the other vehicle is a trailer properly attached and
connected to Toyota’s official
TBC ECU. ( P.181)
●When an approach warning
buzzer is heard often
●When the vehicle is lifted up,
except in the following cases.
• When using a Toyota official lift kit up to 4 in. (101 mm), includ-
ing tire height. Aftermarket lift
kits may degrade system perfor-
mance.
