4-5. Using the driving support systems

When constant speed control 
mode is selected, your vehicle 
will maintain a set speed without 
controlling the vehicle-to-vehi-
cle distance. Select this mode 
only when vehicle-to-vehicle dis-
tance control mode does not 
function correctly due to a dirty 
radar, etc.

With the cruise control off, 
press and hold the cruise 
control main switch for 1.5 
seconds or more.

Immediately after the switch is 

pressed, the dynamic radar cruise 

control indicator will come on. After-

wards, it switches to the cruise con-

trol indicator.
Switching to constant speed control 

mode is only possible when operat-

ing the switch with the cruise con-

trol off.

Accelerate or decelerate, 
with accelerator pedal opera-
tion, to the desired vehicle 
speed (at or above approxi-
mately 20 mph [30 km/h]) 
and press the “-SET” switch 
to set the speed.

Cruise control “SET” indicator will 

come on.
The vehicle speed at the moment 

the switch is released becomes the 

set speed.

Dynamic radar cruise control 

can be set when

●

Vehicles with a continuously vari-

able transmission: The shift lever 

is in D.

●

Vehicles with a manual transmis-

sion: The shift lever is in range 

2nd or higher.

●

Depending on the control mode, 

this item can be set at the follow-

ing speeds.

trol mode: Approximately 20 mph 

(30 km/h) or more

• Constant speed control mode: 

Approximately 20 mph (30 km/h) 

or more

■

Accelerating after setting the 

vehicle speed

The vehicle can accelerate by oper-

ating the accelerator pedal. After 

accelerating, the set speed 

resumes. However, during vehi-

cle-to-vehicle distance control 

mode, the vehicle speed may 

decrease below the set speed in 

order to maintain the distance to the 

preceding vehicle.

RSA (Road Sign 

Assist)

*

The RSA system recognizes 
specific road signs using 
the front camera 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 dis-
play and warning buzzer.

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 replace-

ment for a driver’s own vision and 

awareness. Drive safely by 

always paying careful attention to 

the traffic rules.

Indication on the 
multi-information display

234

4-5. Using the driving support systems

The following types of road 
signs, including electronic signs 
and blinking signs, are recog-
nized.

A non-official or a recently intro-
duced traffic sign may not be recog-
nized.

In the following situations, the 
RSA system will alert the driver.


When the vehicle speed 
exceeds the speed warning 
threshold of the speed limit 
sign displayed, the sign dis-
play will be emphasized and a 
buzzer will sound.



When the RSA system recog-
nizes a do not enter sign and 
determines that your vehicle 
has entered a no-entry area, 

the displayed sign will flash 
and a buzzer will sound.

Depending on the situation, traf-
fic environment (traffic direction, 
speed unit) may be detected 
incorrectly and a warning dis-
play may not operate properly.

The Blind Spot Monitor is a 
system that uses rear side 
radar sensors installed on 
the inner side of the rear 
bumper on the left and right 
side to assist the driver in 
confirming safety when 
changing lanes.

WARNING

■

Cautions regarding the use of 

the system

The driver is solely responsible for 

safe driving. Always drive safely, 

taking care to observe your sur-

roundings.
The Blind Spot Monitor is a sup-

plementary function which alerts 

the driver that a vehicle is in a 

blind spot of the outside rear view 

mirrors or is approaching rapidly 

from behind into a blind spot. Do 

not overly rely on the Blind Spot 

Monitor. As the function cannot 

judge if it is safe to change lanes, 

over reliance could lead to an 

accident resulting in death or seri-

ous injury.
As the system may not function 

correctly under certain condi-

tions, the driver’s own visual con-

firmation of safety is necessary.

WARNING

■

Handling the rear side radar 

sensor

Blind Spot Monitor sensors are 

installed behind the left and right 

sides of the rear bumper respec-

tively. Observe the following to 

ensure the Blind Spot Monitor can 

operate correctly.

●

Keep the sensors and the sur-

rounding areas on the rear 

bumper clean at all times.

If a sensor or its surrounding area 
on the rear bumper is dirty or cov-
ered with snow, the Blind Spot 
Monitor may not operate and a 
warning message (P.236) will 
be displayed. In this situation, 
clear off the dirt or snow and drive 
the vehicle with the operation con-
ditions of the BSM function 
(P.240) satisfied for approxi-
mately 10 minutes. If the warning 
message does not disappear, 
have the vehicle inspected by 
your Toyota dealer.

●

Do not attach accessories, 

stickers (including transparent 

stickers), aluminum tape, etc. to 

a sensor or its surrounding area 

on the rear bumper.

●

Do not subject a sensor or its 

surrounding area on the rear 

bumper to a strong impact.

If a sensor is moved even 

slightly off position, the system 

may malfunction and vehicles 

may not be detected correctly.

In the following situations, have 

your vehicle inspected by your 

Toyota dealer.

• A sensor or its surrounding area 

is subject to a strong impact.

• If the surrounding area of a sen-

sor is scratched or dented, or 

part of them has become dis-

connected.

●

Do not disassemble the sensor.

●

Do not modify the sensor or sur-

rounding area on the rear 

bumper.

●

If a sensor or the rear bumper 

needs to be removed/installed 

or replaced, contact your Toyota 

dealer.

●

Do not paint the rear bumper 

any color other than an official 

Toyota color.

Screen description

The rear view monitor system screen will be displayed if the shift 
lever is shifted to R while the engine switch is in ON.

Vehicle width extension guide line

Displays a guide path when the vehicle is being backed straight up. The 
displayed width is wider than the actual vehicle width.

Vehicle center guide line

This line indicates the estimated vehicle center on the ground.

Distance guide line

Displays a point approximately 1.5 ft. (0.5 m) (red) from the edge of the 
bumper.

Distance guide line

Displays a point approximately 3 ft. (1 m) (blue) from the edge of the 
bumper.

Area displayed on screen

Corners of bumper

The rear view monitor system 
displays an image of the view 
from the bumper of the rear area 
of the vehicle.
The image adjustment proce-
dure for the rear view monitor 
system screen is the same as 
the procedure for adjusting the 
screen. (P.274)


The area displayed on the 
screen may vary according to 
vehicle orientation conditions.



Objects which are close to 
either corner of the bumper or 
under the bumper cannot be 
displayed.



The camera uses a special 
lens. The distance of the 
image that appears on the 
screen differs from the actual 
distance.



Items which are located 
higher than the camera may 
not be displayed on the moni-
tor.

Rear view monitor system 
camera

The camera for the rear view 
monitor system is located as 
shown in the illustration.


Using the camera

If dirt or foreign matter (such as 
water droplets, snow, mud etc.) is 
adhering to the camera, it cannot 
transmit a clear image. In this case, 
flush it with a large quantity of water 
and wipe the camera lens clean 
with a soft and wet cloth.

Differences between the 
screen and the actual road

The distance guide lines and the 
vehicle width guide lines may 
not actually be parallel with the 
dividing lines of the parking 
space, even when they appear

to be so. Be sure to check visu-
ally.
The distances between the vehi-
cle width guide lines and the left 
and right dividing lines of the 
parking space may not be equal, 
even when they appear to be 
so. Be sure to check visually.
The distance guide lines give a 
distance guide for flat road sur-
faces. In any of the following sit-
uations, there is a margin of 
error between the fixed guide 
lines on the screen and the 
actual distance/course on the 
road.


When the ground behind the 
vehicle slopes up sharply

The distance guide lines will appear 
to be closer to the vehicle than the 
actual distance. Because of this, 
objects will appear to be farther 

away than they actually are. In the 
same way, there will be a margin of 
error between the guide lines and 
the actual distance/course on the 
road.



When the ground behind the 
vehicle slopes down sharply

The distance guide lines will appear 
to be further from the vehicle than 
the actual distance. Because of 
this, objects will appear to be closer 
than they actually are. In the same 
way, there will be a margin of error 
between the guide lines and the 
actual distance/course on the road.

A margin of error

When any part of the vehicle sags 
due to the number of passengers or 
the distribution of the load, there is 
a margin of error between the fixed 
guide lines on the screen and the 
actual distance/course on the road.

■

When approaching 
three-dimensional objects

The distance guide lines are dis-
played according to flat surfaced 
objects (such as the road). It is 
not possible to determine the 
position of three-dimensional 
objects (such as vehicles) using 
the distance guide lines. When 
approaching a three-dimen-
sional object that extends out-
ward (such as the flatbed of a 
truck), be careful of the follow-
ing.

Vehicle width guide lines

Vehicle width guide lines

Visually check the surroundings 
and the area behind the vehicle. In 
the case shown below, the truck 
appears to be outside of the vehicle 
width guide lines and the vehicle 
does not look as if it hits the truck. 
However, the rear body of the truck 
may actually cross over the vehicle 
width guide lines. In reality if you 
back up as guided by the vehicle 
width guide lines, the vehicle may 
hit the truck.
