PCS (Pre-Collision System)
The pre-collision system uses a radar sensor and front camera
to detect objects (P. 273) in front of the vehicle. When the sys-
tem determines that the possibility of a frontal collision with an
object is high, a warning operates to urge the driver to take eva-
sive action and the potential brake pressure is increased to help
the driver avoid the collision. If the system determines that the
possibility of a frontal collision with an object is extremely high,
the brakes are automatically applied to help avoid the collision
or help reduce the impact of the collision.
The pre-collision system can be disabled/enabled and the warning
timing can be changed. (P. 277)

Detectable objects
The system can detect the following:
O Vehicles
O Bicyclists
O Pedestrians

System functions
Q 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.
Q Pre-collision brake assist
When the system determines that the possibility of a frontal colli-
sion is high, the system applies greater braking force in relation to
how strongly the brake pedal is depressed.
Q 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.

WARNING
Q Limitations of the pre-collision system
OThe driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-collision system instead of normal braking operations
under any circumstances. This system will not prevent collisions or lessen
collision damage or injury in every situation. Do not overly rely on this sys-
tem. Failure to do so may lead to an accident, resulting in death or serious
injury.
OAlthough this system is designed to help avoid a collision or help reduce
the impact of the collision, its effectiveness may change according to vari-
ous conditions, therefore the system may not always be able to achieve
the same level of performance.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• Conditions under which the system may operate even if there is no pos-
sibility of a collision: P. 279
4
• Conditions under which the system may not operate properly: P. 281
ODo not attempt to test the operation of the pre-collision system yourself.
Depending on the objects used for testing (dummies, cardboard objects
imitating detectable objects, etc.), the system may not operate properly,
possibly leading to an accident.
Q Pre-collision braking
OWhen the pre-collision braking function is operating, a large amount of
braking force will be applied.
OIf the vehicle is stopped by the operation of the pre-collision braking func-
tion, the pre-collision braking function operation will be canceled after
approximately 2 seconds. Depress the brake pedal as necessary.
OThe pre-collision braking function may not operate if certain operations are
performed by the driver. If the accelerator pedal is being depressed
strongly or the steering wheel is being turned, the system may determine
that the driver is taking evasive action and possibly prevent the pre-colli-
sion braking function from operating.
O In some situations, while the pre-collision braking function is operating,
operation of the function may be canceled if the accelerator pedal is
depressed strongly or the steering wheel is turned and the system deter-
mines that the driver is taking evasive action.
O If the brake pedal is being depressed, the system may determine that the
driver is taking evasive action and possibly delay the operation timing of
the pre-collision braking function.
276

WARNING
Q When to disable the pre-collision 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:
OWhen the vehicle is being towed
OWhen your vehicle is towing another vehicle
O When transporting the vehicle via truck, boat, train or similar means of
transportation
O When the vehicle is raised on a lift with the engine running and the tires
are allowed to rotate freely
O When inspecting the vehicle using a drum tester such as a chassis
dynamometer or speedometer tester, or when using an on vehicle wheel
balancer
OWhen a strong impact is applied to the front bumper or front grille, due to
an accident or other reasons
O If the vehicle cannot be driven in a stable manner, such as when the vehi-
cle has been in an accident or is malfunctioning
O When the vehicle is driven in a sporty manner or off-road
O When the tires are not properly inflated
O When the tires are very worn
O When tires of a size other than specified are installed
OWhen tire chains are installed
O When a compact spare tire or an emergency tire puncture repair kit is used
O If equipment (snow plow, etc.) that may obstruct the radar sensor or front
camera is temporarily installed to the vehicle

LDA (Lane Departure Alert With Yaw Assist
Function)
Summary of functions
When driving on a road with clear white (yellow) lane lines, this func-
tion alerts the driver when the vehicle might depart from its lane or
course* and provides assistance by applying a brake force to keep
the vehicle in its lane or course*.
The LDA system recognizes white
(yellow) lane lines or a course*
using the front camera. Addition-
ally, it detects preceding vehicles
using the front camera and radar.
*: Boundary between asphalt and the
side of the road, such as grass,
soil, or a curb
WARNING
Q Before using LDA system
ODo not rely solely upon the LDA system. The LDA system does not auto-
matically drive the vehicle or reduce the amount of attention that must be
paid to the area in front of the vehicle. The driver must always assume full
responsibility for driving safely by paying careful attention to the surround-
ing conditions and operating the steering wheel to correct the path of the
vehicle. Also, the driver must take adequate breaks when fatigued, such
as from driving for a long period of time.
OFailure to perform appropriate driving operations and pay careful attention
may lead to an accident, resulting in death or serious injury.
O When not using the LDA system, use the LDA switch to turn the system
off.

RSA (Road Sign Assist)
Summary of function
The RSA system recognizes spe-
cific road signs using the front
camera and/or navigation system
(when speed limit information is
available) to provide information
to the driver via the display.
If the system judges that the vehicle is being driven over the speed
limit, performing prohibited actions, etc., according to the recognized
road signs, it notifies the driver through a visual notification and notifi-
4
cation buzzer.
WARNING
Q Before using the RSA
Do not rely solely upon the RSA system. RSA is a system which supports
the driver by providing information, but it is not a replacement for a driver’s
own vision and awareness. Drive safely by always paying careful attention
to the traffic rules.

Notification function
In the following situations, the RSA system will notify the driver.
O When the vehicle speed exceeds the speed notification threshold of
the speed limit sign displayed, the sign display will be emphasized
and a buzzer will sound.
O When the RSA system recognizes a no-entry sign and detects that
the vehicle has entered a no-entry area based on the map informa-
tion of the navigation system, the no-entry sign flashes and a
buzzer will sound. (For vehicles with navigation system)
O If it is detected that your vehicle is overtaking when a no overtaking
sign is displayed on the multi-information display, the displayed sign
will flash and a buzzer will sound.
Depending on the situation, traffic environment
(traffic direction,
speed unit) may be detected incorrectly and a notification function

may not operate properly.
QSetting procedure
Setting for “RSA” in
of the multi-information display is set to “On”
(P. 139)
Q Automatic turn-off of RSA sign display
One or more signs automatically turn off in the following situations.
O No sign has been recognized for a certain distance.
O The road changes due to a left or right turn, etc.
Q Conditions in which the function may not operate or detect correctly
In the following situations, RSA does not operate normally and may not rec-
ognize signs, display the incorrect sign, etc. However, this does not indicate a
malfunction.
O The front camera is misaligned due to a strong impact being applied to the
sensor, etc.
O Dirt, snow, stickers, etc. are on the windshield near the front camera.
O In inclement weather such as heavy rain, fog, snow or sand storms.

O If a sign not appropriate for the currently traveled lane, but the sign exists
directly after a freeway branches, or in an adjacent lane just before merging.
O Stickers are attached to the rear of the preceding vehicle.
O A sign resembling a system compatible sign is recognized.
OSide road speed signs may be detected and displayed (if positioned in sight
of the front camera) while the vehicle is traveling on the main road.
O Roundabout exit road speed signs may be detected and displayed (if posi-
tioned in sight of the front camera) while traveling on a roundabout.
O The front of the vehicle is raised or lowered due to the carried load.
O The surrounding brightness is not sufficient or changes suddenly.
O When a sign intended for trucks, etc. is recognized.
O The vehicle is driven in a country with a different direction of traffic.
O The navigation system map data is outdated.
OThe navigation system is not operating.
O The speed information displayed on the meter and on the navigation system
may be different due to the navigation system using map data.
Q Speed limit sign display
If the engine switch was last turned to the “LOCK” position (vehicles without
smart entry & start system) or off (vehicles with smart entry & start system)
while a speed limit sign was displayed on the multi-information display, the
same sign displays again when the engine switch is turned to the “ON” posi-
tion (vehicles without smart entry & start system) or IGNITION ON mode
(vehicles with smart entry & start system).
Q If “RSA Malfunction Visit Your Dealer” is shown
The system may be malfunctioning. Have the vehicle inspected by any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
Q Customization
Some functions can be customized. (Customizable features: P. 647)

Dynamic radar cruise control
Summary of functions
In vehicle-to-vehicle distance control mode, the vehicle automatically
accelerates and decelerates to match the speed changes of the pre-
ceding vehicle even if the accelerator pedal is not depressed. In con-
stant speed control mode, the vehicle runs at a fixed speed.
Use the dynamic radar cruise control on freeways and highways.
O Vehicle-to-vehicle distance control mode (P. 305)
O Constant speed control mode (P. 311)

WARNING
Q Before using dynamic radar cruise control
ODriving safely is the sole responsibility of the driver. Do not rely solely on
the system, and drive safely by always paying careful attention to your sur-
roundings.
OThe dynamic radar cruise control provides driving assistance to reduce the
driver’s burden. However, there are limitations to the assistance provided.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• When the sensor may not be correctly detecting the vehicle ahead:
P. 315
• Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly: P. 316
OSet the speed appropriately depending on the speed limit, traffic flow, road
conditions, weather conditions, etc. The driver is responsible for checking
the set speed.
OEven when the system is functioning normally, the condition of the preced-
ing vehicle as detected by the system may differ from the condition
observed by the driver. Therefore, the driver must always remain alert,
assess the danger of each situation and drive safely. Relying solely on this
system or assuming the system ensures safety while driving can lead to
an accident, resulting in death or serious injury.
O Switch the dynamic radar cruise control setting to off, using the “ON-OFF”
button when not in use.
