RSA (Road Sign Assist)
The RSA system recognizes spe-
cific road signs using the front
camera and/or navigation system
(when data 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., in relation to the recognized
road signs, it alerts the driver using a warning display and warning
buzzer.
: If equipped
Summary of function
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.

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. 381
• Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly: P. 382
● 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.

WARNING
■Cautions regarding the driving assist systems
Observe the following precautions, as there are limitations to the assistance
provided by the system. Failure to do so may cause an accident resulting in
death or serious injury.
● Assisting the driver to measure following distance
The dynamic radar cruise control is only intended to help the driver in
determining the following distance between the driver’s own vehicle and a
designated vehicle traveling ahead. It is not a mechanism that allows care-
less or inattentive driving, and it is not a system that can assist the driver in
low-visibility conditions.
It is still necessary for driver to pay close attention to the vehicle’s sur-
roundings.
● Assisting the driver to judge proper following distance
The dynamic radar cruise control det ermines whether the following dis-
tance between the driver’s own vehicle and a designated vehicle traveling
ahead is within a set range. It is not capable of making any other type of
judgement. Therefore, it is absolutely necessary for the driver to remain
vigilant and to determine whether or not there is a possibility of danger in
any given situation.
● Assisting the driver to operate the vehicle
The dynamic radar cruise control does not include functions which will pre-
vent or avoid collisions with vehicles ahead of your vehicle. Therefore, if
there is ever any possibility of danger, the driver must take immediate and
direct control of the vehicle and act appropriately in order to ensure the
safety of all involved.

When this function is enabled and the system is operating in vehicle-
to-vehicle distance control mode ( P. 371), when a speed limit sign is
detected, the recognized speed limit will be displayed with an up/
down arrow. The set speed can be increased/reduced to the recog-
nized speed limit by pushing the lever up or down.
● When the current set speed is
lower than the recognized
speed limit
Push the lever up
● When the current set speed is
higher than the recognized
speed limit
Push the lever down
Dynamic Radar Cruise Control with Road Sign Assist can be enabled/
disabled in on the multi-information display. ( P. 151)

■ Automatic cancelation of constant speed control mode
Constant speed control mode is automatically canceled in the following situa-
tions:
● Actual vehicle speed is more than approximately 16 km/h (10 mph) below
the set vehicle speed.
● Actual vehicle speed falls below approximately 30 km/h (20 mph).
● VSC is activated.
● TRC/A-TRC is activated for a period of time.
● When the VSC, TRC/A-TRC system is turned off.
● Pre-collision braking is activated.
● 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 constant speed 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.
■ The Dynamic Radar Cruise Control with Road Sign Assist may not oper-
ate properly when
As the Dynamic Radar Cruise Control with Road Sign Assist may not oper-
ate properly in conditions in which RSA may not operate or detect correctly
( P. 365), when using this function, make sure to check the speed limit
sign displayed.
In the following situations, the set speed may not be changed to the recog-
nized speed limit by pushing the lever up or down.
● If speed limit information is not available
● When the recognized speed limit is the same as the set speed
● When the recognized speed limit is outside of the speed range that the
dynamic radar cruise control system can operate
■ Brake operation
A brake operation sound may be heard and the brake pedal response may
change, but these are not malfunctions.
■ Warning messages and buzzers for dynamic radar cruise control
Warning messages and buzzers are used to indicate a system malfunction or
to inform the driver of the need for caution while driving. If a warning message
is shown on the multi-information display, read the message and follow the
instructions. ( P. 337, 643)

Rear view monitor system
The rear view monitor system will
activate when the shift lever is in
R. ( P. 293, 300)
The rear view monitor system will
be deactivated when the shift lever
is in any position other than R.
When the shift lever is shifted to
the R position and any mode but-
ton (such as “SETUP”) is pressed,
the rear view monitor system is
canceled, and the screen is
switched to the mode of the button
that was pressed.
: If equipped
The rear view monitor system assists the driver by displaying an
image of the view behind the vehicle with fixed guide lines while
backing up, for example while parking.
The screen illustrations used in this text are intended as examples,
and may differ from the image that is actually displayed on the
screen.

WARNING
■When using the rear view monitor system
The rear view monitor system is a supplemental device intended to assist
the driver when backing up. When backing up, be sure to visually check all
around the vehicle both directly and using the mirrors before proceeding.
Observe the following precautions to avoid an accident that could result in
death or serious injuries.
● Never depend on the rear view monitor system entirely when backing up.
The image and the position of the guide lines displayed on the screen may
differ from the actual state.
Use caution, just as you would when backing up any vehicle.
● Be sure to back up slowly, depressing the brake pedal to control vehicle
speed.
● The instructions given are only guide lines.
When and how much to turn the steering wheel will vary according to traf-
fic conditions, road surface conditions , vehicle condition, etc. when park-
ing. It is necessary to be fully aware of this before using the rear view
monitor system.
● When parking, be sure to check that the parking space will accommodate
your vehicle before maneuvering into it.
● Do not use the rear view monitor system in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains
• When the tailgate is not closed completely
• On roads that are not flat or straight, such as curves or slopes.
● In low temperatures, the screen may darken or the image may become
faint. The image could distort when the vehicle is moving, or you may
become unable to see the image on the screen. Be sure to visually check
all around the vehicle both directly and using the mirrors before proceed-
ing.
● If the tire sizes are changed, the position of the fixed guide lines displayed
on the screen may change.
● The camera uses a special lens. The distances between objects and
pedestrians that appear in the image displayed on the screen will differ
from the actual distances.
