any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
● “Lane Departure Alert Unavailable”
• The system is temporarily canceled due to a malfunction in a sensor
other than the front camera. Turn the LDA system off, wait for a little
while, and then turn the LDA system back on.
• The system is temporarily unavaila ble as the vehicle repeatedly departs
from its lane or course* in a short period of time. Turn the engine switch
to the “LOCK” position (vehicles without smart entry & start system) or off
(vehicles with smart entry & start system), and then turn it to the “ON”
position (vehicles without smart entry & start system) or IGNITION ON
mode (vehicles with smart entry & start system) again.
*: Boundary between asphalt and the side of the road, such as grass, soil, or
a curb
● “LDA Unavailable at Current Speed”
The function cannot be used as the vehicle speed exceeds the LDA opera-
tion range. Drive slower.
■ Customization
Function settings can be changed. (Customizable features: P. 648)

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 emphasized
and a buzzer will sound.
● 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)
● 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.
■ Setting procedure
Setting for “RSA” in of the multi-information display is set to “On”
( P. 137)
■ Automatic turn-off of RSA sign display
One or more signs automatically turn off in the following situations.
● No sign has been recognized for a certain distance.
● 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 rec-
ognize signs, display the incorrect sign, etc. However, this does not indicate a
malfunction.
● 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.
● Light from an oncoming vehicle, the sun, etc. enters the front camera.
● The sign is dirty, faded, tilted or bent.
● The contrast of electronic sign is low.

WARNING
■Before using dynamic radar cruise control
● Driving 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.
● The 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. 314
• Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly: P. 315
● Set the speed appropriately depending on the speed limit, traffic flow, road
conditions, weather conditions, etc. The driver is responsible for checking
the set speed.
● Even 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, t he 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.
● Switch the dynamic radar cruise control setting to off, using the “ON-OFF”
button when not in use.

■Dynamic radar cruise control can be set when
● The shift lever is in D. (Vehicles with automatic transmission)
● The shift lever is in range 2nd or higher. (Vehicles with manual transmission)
● Depending on the control mode, this item can be set at the following
speeds.
• Vehicle-to-vehicle distance control mode: Approximately 30 km/h (20
mph) or more
• Constant speed control mode: Approximately 30 km/h (20 mph) or more
■ Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After acceler-
ating, the set speed resumes. However, during vehicle-to-vehicle distance
control mode, the vehicle speed may decrease below the set speed in order
to maintain the distance to the preceding vehicle.
■ Shift position selection (vehicles with manual transmission)
Select a shift position according to the vehicle speed. If the engine speed is
too high or too low, control may be automatically canceled.
■ Automatic cancelation of vehicle-to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the fol-
lowing situations.
● Actual vehicle speed falls below approximately 25 km/h (16 mph).
● VSC is activated.
● TRC/A-TRC is activated for a period of time.
● When the VSC or TRC/A-TRC system is turned off.
● The sensor cannot detect correctly because it is covered in some way.
● When the brake control or output restriction control of a driving support sys-
tem operates. (For example: Pre-Coll ision System, Drive-Start Control)
● When the shift lever is in N or the clutch pedal is depressed for a certain
amount of time or more. (Vehicles with manual transmission)
● 4WD models: Switching the transfer mode is not completed within 5 sec-
onds while the cruise control system is on.
If vehicle-to-vehicle distance control mode is automatically canceled for any
reasons other than the above, there may be a malfunction in the system.
Contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer.

■ When the sensor may not be correctly detecting the vehicle ahead
In the case of the following and depending on the conditions, operate the
brake pedal when deceleration of the system is insufficient or operate the
accelerator pedal when acceleration is required.
As the sensor may not be able to correctly detect these types of vehicles, the
approach warning ( P. 309) may not be activated.
● Vehicles that cut in suddenly
● Vehicles traveling at low speeds
● Vehicles that are not moving in the same lane
● Vehicles with small rear ends (trailers with no load on board, etc.)
● Motorcycles traveling in the same lane
● When water or snow thrown up by the surrounding vehicles hinders the
detecting of the sensor
● When your vehicle is pointing upwards
(caused by a heavy load in the luggage
compartment, etc.)
● Preceding vehicle has an extremely high
ground clearance

■ Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly
In the case of the following conditions, operate the brake pedal (or accelera-
tor pedal, depending on the situation) as necessary.
As the sensor may not be able to correctly detect vehicles ahead, the system
may not operate properly.
● When the vehicle ahead of you decelerates suddenly
● When driving on a road surrounded by a structure, such as in a tunnel or on
a bridge
● While the vehicle speed is decreasing to the set speed after the vehicle
accelerates by depressing the accelerator pedal
● When the road curves or when the lanes
are narrow
● When steering wheel operation or your
