■Warning message
If the following warning message is displayed on the multi-information display
and the LTA indicator illuminates in yellow, 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 properly. Have the vehicle inspected by
your Toyota dealer.
●“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 operation
range. Drive slower.
■Customization
Function settings can be changed. (P. 109, 126)

2824-5. Using the driving support systems
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-
cation buzzer
*.
*: This setting needs to be customized.

WARNING
■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.

When the front camera recognizes a sign and/or information of a sign
is available from the navigation system, the sign will be displayed on
the multi-information display.
●When the driving assist system
information is selected, a maxi-
mum of 3 signs can be dis-
played. (P. 104, 117)
●When a tab other than the driv-
ing assist system information is
selected, the following types of
road signs will be displayed.
(P. 104, 117)
• Speed limit sign
• Do Not Enter sign (when notifi-
cation is necessary)
If signs other than speed limit
signs are recognized, they will
be displayed in an overlapping
stack under the current speed
limit sign.

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 do not enter sign and deter-
mines that your vehicle has entered a no-entry area, the displayed
sign will flash and a buzzer will sound.
Depending on the situation, a notification function may not operate
properly.

■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.

■Speed limit sign display
If the power switch was last turned off while a speed limit sign was displayed
on the multi-information display, the same sign displays again when the
power switch is turned to ON.

The system may be malfunctioning. Have the vehicle inspected by your Toy-
ota dealer.

In vehicle-to-vehicle distance control mode, the vehicle automatically
accelerates, decelerates and stops to match the speed changes of the
preceding vehicle even if the accelerator pedal is not depressed. In
constant speed control mode, the vehicle runs at a fixed speed.
Use the dynamic radar cruise control with full-speed range on free-
ways and highways.

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 paying careful attention to your sur-
roundings.
●The dynamic radar cruise control with full-speed range 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. 301
• Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly: P. 302
●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, 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.
●Switch the dynamic radar cruise control with full-speed range setting to off,
using the cruise control main switch when not in use.
