Driving
In the following situations, the RSA system alerts the driver using a
warning display.
●When the vehicle speed exceeds the speed warning threshold
applied to the speed limit of the sign displayed on the main display
or multi-information display, the sign color becomes inverted.
●If it is detected that your vehicle is overtaking when a no overtaking
sign is displayed on the multi-information display, the sign flashes.
Depending on the situation, traffic environment (traffic direction,
speed, unit) may be detected incorrectly and a warning display may
not operate properly.
■Automatic turn-off of RSA sign display
One or more signs automatically turn off in the following situations.
●A new sign is not 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 camera sensor is misaligned due to a strong impact being applied to
the sensor, etc.
●Dirt, snow, stickers, etc., are on the windshield near the camera sensor.
●In inclement weather such as heavy rain, fog, snow or sand storms
●Light from an oncoming vehicle, the sun, etc., enters the camera sensor.
●The sign is dirty, faded, tilted or bent, and if an electronic sign, the contrast
is poor.
●All or part of the sign is hidden by the leaves of a tree, a pole, etc.
●The sign is only visible to the camera sensor for a short amount of time.
●The driving scene (turning, lane change, etc.) is judged incorrectly.
●Even if it is a sign not appropriate for the currently traveled lane, such a sign
exists directly after a freeway branches, or in an adjacent lane just before
merging.
●Stickers are attached to the rear of the preceding vehicle.
●A sign resembling a system compatible sign is recognized.
●The vehicle is driven in a country with a different direction of traffic.

Driving
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle distance can also be set by operating the vehicle-to-vehicle dis-
tance button.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pushing the
cruise control lever up or depressing the accelerator pedal will resume fol-
low-up cruising.
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.

lever is operated
Large adjustment: Increases or decreases in 5 km/h (3.1 mph)
*1 or 5 mph
(8 km/h)
*2 increments for as long as the lever is held
In the constant speed control mode (P. 407), the set speed will be
increased or decreased as follows:
Fine adjustment: By 1 km/h (0.6 mph)*1 or 1 mph (1.6 km/h)*2 each time
the lever is operated
Large adjustment: The speed will continue to change while the lever is
held.
*1: When the set speed is shown in “km/h”
*2: When the set speed is shown in “MPH”

■If “Clean Parking Assist Sensor” is displayed on the multi-information
display
A sensor may be dirty or covered with snow or ice. In such cases, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a malfunction dis-
play may appear or an obstacle may not be detected. If the sensor thaws out,
the system should return to normal.
■ If “Parking Assist Malfunction” is displayed on the multi-information dis-
play
Depending on the malfunction of the sensor, the device may not be working
normally. Have the vehicle inspected by any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
■ Customization
Setting of buzzer volume can be changed.
(Customizable features: P. 708)
WARNING
■When using Toyota parking assist-sensor
Observe the following precautions to avoid an unexpected accident.
● Do not exceed the speed limit of 10 km/h (6 mph).
● The sensors’ detection areas and reaction times are limited. When moving
forward or reversing, check the areas surrounding the vehicle (especially
the sides of the vehicle) for safety, and drive slowly, using the brake to
control the vehicle’s speed.
● Do not install accessories within the sensors’ detection areas.

■Intelligent Clearance Sonar function while the Simple Intelligent Parking
Assist System is operating
While the Simple Intelligent Parking Assist System is operating, if the system
detects an obstacle that could result in a collision, hybrid system output
restriction control and brake control of the Intelligent Clearance Sonar func-
tion are operated, regardless of whether the Intelligent Clearance Sonar func-
tion is on or off. (P. 445)
●After the Intelligent Clearance Sonar function operates, operation of the
Simple Intelligent Parking Assist System is temporarily stopped, and opera-
tion of the Intelligent Clearance Sonar function is indicated on the multi-
information display. (P. 449)
●When operation of the Simple Intelligent Parking Assist System is stopped 3
times by operation of the Intelligent Clearance Sonar function, the Simple
Intelligent Parking Assist System is canceled.
●Once the Simple Intelligent Parking Assist System becomes available after
the Intelligent Clearance Sonar function is operated, a message prompting
you to shift is displayed on the multi-information display. Operation of the
Simple Intelligent Parking Assist System can be resumed by shifting accord-
ing to the prompt on the multi-information display and pressing the S-IPA
switch (P. 459) again.
■Shifting while the Simple Intelligent Parking Assist System is operating
If the system determines that the drivers intends to move forward or in
reverse, assistance continues even if the drivers shifted before being
prompted to do so by the system. However, because driver operation differs
from the guidance provided by the system, the number of turning maneuvers
may increase.
■Customization
Settings (e.g. the obstacle detection range) can be changed. (Customizable
features: P. 708)

■Function summary
If a parking space can be detected, you will be guided forward until
you reach the assist control starting position, and then the parallel
parking assist mode can be used. Furthermore, depending on the
parking space and other conditions, multi-turn maneuvering assist
control is also provided if necessary.
Continue moving forward
with the vehicle parallel to
the curb or road, and stop so
that the center of the target
parking spot appears nearly
perpendicular to the vehicle.
Then press the S-IPA switch
1 time to select the parallel
parking assist mode.
Travel straight ahead paral-
lel with the road or curb so
that the parking space is
detected.
A sound is issued and a display is shown to notify you when the
vehicle reaches a position where assist control can be used to
begin backing up from, and then when the shift position is
changed according to guidance provided by the system, steering
wheel auto operation begins.
If the detected parking space or road width (distance to the side of the
road across from the parking space) is narrow, or if there are obstacles
in front of the vehicle, guidance will not be issued.
