●Instances of the Blind Spot Moni-
tor unnecessarily d etecting a vehi-
cle and/or object may increase in 
the following situations:
• When the sensor  is misaligned 
due to a strong impact to the sen-
sor or its surrounding area
• When the distance between your  vehicle and a guardrail, wall, etc. 
that enters the detection area is 
short
• When driving up and down con-
secutive steep inclines, such as 
hills, dips in the road, etc.
• When vehicle lanes are narrow, or 
when driving on the edge of a 
lane, and a vehicle traveling in a 
lane other than the adjacent lanes 
enters the detection area
• When driving on roads with sharp  bends, consecutive curves, or 
uneven surfaces
• When the tires are slipping or  spinning
• When the distance between your  vehicle and a following vehicle is 
short
• When an accessory (such as a  bicycle carrier) is installed to the

*: If equipped
RCTA (Rear Cross Traf-
fic Alert)*
The RCTA function uses the 
BSM rear side radar sensors 
installed behind the rear 
bumper. This function is 
intended to assist the driver 
in checking areas that are 
not easily visible when 
backing up.
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 RCTA function is 
only a supplementary function 
which alerts the driver that a vehi-
cle is approaching from the right 
or left at the rear of the vehicle. As 
the RCTA function may not func-
tion correctly under certain condi-
tions, the driver’s own visual 
confirmation of safety is neces-
sary. Over reliance on this func-
tion may lead to an accident 
resulting death or serious injury.

Safe Exit Assist*
The safe exit assist is a sys-
tem that uses rear side 
radar sensors installed on 
the inner side of the rear 
bumper to help occupants 
judge if an approaching 
vehicle or bicycle may col-
lide with a door when open-
ing it or cancel opening of 
the door, to reduce the pos-
sibility of a collision.
WARNING
■Cautions regarding the use of 
the system
●The driver is solely responsible 
for safe driving. Always drive 
safely, taking care to observe 
your surroundings.
●The safe exit assist is a supple-
mentary system that, when the 
vehicle is stopped, informs 
occupants of the existence of 
approaching vehicles and bicy-
cles. As this system alone can-
not be used to judge safety, 
over-reliance on this system 
may lead to an accident result-
ing in death or serious injury.
In certain situations, this system 
may not function to its fullest 
extent. Therefore it is necessary 
for the occupants to visually 
check for safety directly and using 
the mirrors.

WARNING
■To ensure the system can 
operate properly
Safe exit assist sensors are 
installed behind the left and right 
sides of the rear bumper respec-
tively. Observe the following to 
ensure the safe exit assist 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 Safe Exit 
Assist may not operate and a 
warning message will be dis-
played. In this situation, clear off 
the dirt or snow and drive the 
vehicle with the operation condi-
tions of the SEA function satisfied 
for approximatel y 10 minutes. If 
the warning message does not 
disappear, have the vehicle 
inspected by you r 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 mal-
function and vehicles may not be 
detected correctly. In the following 
situations, have your vehicle 
inspected by you r 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 h as become dis-
connected.

WARNING
■Cautions regarding the use of 
the system
There is a limit to the degree of 
recognition accuracy and control 
performance that this system can 
provide, do not ov erly rely on this 
system. The driver is always 
responsible for paying attention to 
the vehicle’ surroundings and 
driving safely.
■To ensure the system can 
operate properly
Observe the following precau-
tions. 
Failing to do so may result in the 
vehicle being unable to be driven 
safely and possibly cause an acci-
dent.
●Do not damage the sensors, 
and always keep them clean.
●Do not attach a sticker or install 
an electronic component, such 
as a backlit license plate (espe-
cially fluorescent type), fog 
lights, fender pole or wireless 
antenna near a radar sensor.
●Do not subject the surrounding 
area of the sensor to a strong 
impact. If subjected to an 
impact, have the vehicle 
inspected by Toyota dealer. If 
the front or rear bumper needs 
to be removed/installed or 
replaced, contact your Toyota 
dealer.
●Do not modify, disassemble or 
paint the sensors.
●Do not attach a license plate 
cover.
●Keep your tires properly 
inflated.
■When to disable the function
In the following situations, disable 
the function as it may operate 
even though there is no possibility 
of a collision.
●Failing to observe the warnings 
above.
●A non-genuine Toyota suspen-
sion (lowered suspension, etc.) 
is installed.
■Notes when washing the vehi-
cle
Do not apply intensive bursts of 
water or steam to the sensor 
area.
Doing so may result in the sensor 
malfunctioning.
●When using a high pressure 
washer to wash the vehicle, do 
not spray the sensors directly, 
as doing so may cause a sensor 
to malfunction.
●When using steam to clean the 
vehicle, do not direct steam too 
close to the sensors as doing so 
may cause a sensor to malfunc-
tion.

Driving
If a sensor is dirty, the position of the 
dirty sensor will be shown on the 
display.
Also, due to ice forming on a sensor 
at low temperatures, a warning 
message may be displayed or the 
sensor may not be able to detect an 
object. Once the ice melts, the sys-
tem will return to normal.
If a warning message is displayed 
even if the sensor is clean, there 
may be a sensor malfunction. Have 
the vehicle inspected by your Toyota 
dealer.
■Sensor detection information
●The sensors may be able to only 
detect objects near the front and 
rear bumpers.
●The following situations may occur 
during use.
• Depending on the shape of the 
object and other  factors, the 
detection distance may shorten, or 
detection may be impossible.
• Detection may be impossible if  static objects draw too close to the 
sensor.
• After the static object detection,  there will be a short delay before a 
graphic is shown on displays, and 
warning buzzer sounds. Even at 
low speeds, there  is a possibility 
that the object will come within the 
sensor’s detecti on areas before 
the display is shown and the warn-
ing beep sounds.
• It might be difficult to hear the  buzzer due to the volume of the 
audio system or air flow noise of 
the air conditioning system.
• It may be difficult to hear the  buzzer if buzzers for other sys-
tems are sounding.
■Objects which the system may 
not be properly detected
The shape of the object may pre-
vent the sensor from detecting it. 
Pay particular attention to the follow-
ing objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials 
that absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with  upper sections 
projecting outwards in the direc-
tion of your vehicle
●People may not be detected if 
they are wearing certain types of 
clothing.
■Situations in which the system 
may not operate properly
Certain vehicle conditions and the 
surrounding environment may affect 
the ability of a sensor to correctly 
detect objects. Part icular instances 
where this may occur are listed 
below.
●There is dirt, snow, water drops or 
ice on a sensor. (Cleaning the 
sensors will resolve this problem.)
●A sensor is froz en. (Thawing the 
area will resolve this problem.) 
In especially cold weather, if a 
sensor is frozen the sensor dis-
play may be displayed abnormally, 
or objects, such as a wall, may not 
be detected.
●When a sensor or the area around 
a sensor is extremely hot or cold.
●On an extremely bumpy road, on 
an incline, on gravel, or on grass.
●When vehicle horns, vehicle 
detectors, motorcycle engines, air 
brakes of large vehicles, the clear-
ance sonar of ot her vehicles or 
other devices which produce ultra-
sonic waves are near the vehicle
●A sensor is coated with a sheet of 
spray or heavy rain.

PKSB (Parking Sup-
por t Brake)*
The PKSB (Parking Support 
Brake) consists of the fol-
lowing functions that oper-
ate when driving at a low 
speed or backing up, such 
as when parking. When the 
system determines that the 
possibility of a collision 
with a detected object is 
high, a warning operates to 
urge the driver to take eva-
sive action. If the system 
determines that the possi-
bility of a collision with a 
detected object is extremely 
high, the brakes are auto-
matically applied to help 
avoid the collision or help 
reduce the impact of the col-
lision.

Brake) system
WARNING
■Cautions regarding the use of 
the system
Do not overly rely on the system, 
as doing so may lead to an acci-
dent.
Always drive while checking the 
safety of the surroundings of the 
vehicle.
Depending on the vehicle and 
road conditions, weather, etc., the 
system may n ot operate.
The detection cap abilities of sen-
sors and radars are limited. 
Always drive while checking the 
safety of the surroundings of the 
vehicle.
●The driver is solely responsible 
for safe driving. Always drive 
carefully, taking care to observe 
your surroundings. The PKSB 
(Parking Support Brake) system 
is designed to provide support 
to lessen the severity of colli-
sions. However, it may not oper-
ate in some situations.
●The PKSB (Parki ng Support 
Brake) system is not designed 
to stop the vehicle completely. 
Additionally, even if the system 
has stopped the vehicle, it is 
necessary to depress the brake 
pedal immediately as brake 
control will be canceled after 
approximately 2 seconds.
●It is extremely dangerous to 
check the system operations by 
intentionally driving the vehicle 
into the direction  of a wall, etc. 
Never attempt such actions.

■ABS (Anti-lock Brake Sys-
tem)
Helps to prevent wheel lock 
when the brakes are applied 
suddenly, or if the brakes are 
applied while driving on a slip-
pery road surface
■Brake assist
Generates an increased level of 
braking force after the brake 
pedal is depressed when the 
system detects a panic stop sit-
uation
■VSC (Vehicle Stability Con-
trol)
Helps the driver to control skid-
ding when swerving suddenly or 
turning on slippery road sur-
faces.
■Enhanced VSC (Enhanced 
Vehicle Stability Control)
Provides cooperative control of 
the ABS, TRAC, VSC and EPS.
Helps to maintain directional 
stability when swerving on slip-
pery road surfaces by con-
trolling steering performance.
■TRAC (Traction Control)
Helps to maintain drive power 
and prevent the drive wheels 
from spinning when starting the 
vehicle or accelerating on slip-
pery roads
■Active Cornering Assist 
(ACA)
Helps to prevent the vehicle 
from drifting to the outer side by 
performing inner wheel brake 
control when attempting to 
accelerate while turning
■Hill-start assist control
Helps to reduce the backward 
movement of the vehicle when 
starting on an uphill
■EPS (Electric Power Steer-
ing)
Employs an electric motor to 
reduce the amount of effort 
needed to turn the steering 
wheel.
■Dynamic Torque Control 
AWD system (AWD models)
Automatically controls the drive 
system such as to front-wheel 
drive or AWD (all wheel drive) 
according to various running 
Driving assist systems
To keep driving safety and 
performance, the following 
systems operate automati-
cally in response to various 
driving situations. Be 
aware, however, that these 
systems are supplementary 
and should not be relied 
upon too heavily when oper-
ating the vehicle.

■Secondary Collision Brake 
operating conditions
The system operates when the SRS 
airbag sensor detects a collision 
while the vehicle is in motion.
However, the system does not oper-
ate when the components are dam-
aged.
■Secondary Collision Brake 
automatic cancellation
The system is automatically can-
celed in any of th e following situa-
tions.
●The vehicle speed drops below 
approximately 0 mph (0 km/h)
●A certain amount o f time elapses 
during operation
●The accelerator pedal is 
depressed a large amount
WARNING
■The ABS does not operate 
effectively when
●The limits of tire gripping perfor-
mance have been exceeded 
(such as excessively worn tires 
on a snow covered road).
●The vehicle hydroplanes while 
driving at high speed on wet or 
slick roads.
■Stopping distance when the 
ABS is operating may exceed 
that of normal conditions
The ABS is not designed to 
shorten the vehicle’s stopping dis-
tance. Always maintain a safe dis-
tance from the vehicle in front of 
you, especially in  the following sit-
uations:
●When driving on d irt, gravel or 
snow-covered roads
●When driving with tire chains
●When driving over bumps in the 
road
●When driving over roads with 
potholes or uneven surfaces
■TRAC/VSC may not operate 
effectively when
Directional control and power may 
not be achievable while driving on 
slippery road surfaces, even if the 
TRAC/VSC system is operating. 
Drive the vehicle  carefully in con-
ditions where stability and power 
may be lost.
■Active Cornering Assist does 
not operate effectively when
●Do not overly rely on Active 
Cornering Assist. Active Corner-
ing Assist may not operate 
effectively when accelerating 
down slopes or driving on slip-
pery road surfaces.
●When Active Corn ering Assist 
frequently operates, Active Cor-
nering Assist may temporarily 
stop operating to ensure proper 
operation of the brakes, TRAC 
and VSC.
■Hill-start assist control does 
not operate effectively when
●Do not overly rely on hill-start 
assist control. Hill-start assist 
control may not operate effec-
tively on steep inclines and 
roads covered with ice.
●Unlike the parking brake, 
hill-start assist control is not 
intended to hold the vehicle sta-
tionary for an extended period 
of time. Do not attempt to use 
hill-start assist control to hold 
the vehicle on an incline, as 
doing so may lead to an acci-
dent.

2784-5. Using the driving support systems
WARNING
■When the TRAC/VSC is acti-
vated
The slip indicator light flashes. 
Always drive carefully. Reckless 
driving may cause an accident. 
Exercise particular care when the 
indicator light flashes.
■When the TRAC/VSC systems 
are turned off
Be especially careful and drive at 
a speed appropriate to the road 
conditions. As these are the sys-
tems to help ensure vehicle stabil-
ity and driving force, do not turn 
the TRAC/VSC systems off 
unless necessary.
■Replacing tires
Make sure that all tires are of the 
specified size, brand, tread pat-
tern and total load capacity. In 
addition, make sure that the tires 
are inflated to the recommended 
tire inflation pressure level.
The ABS, TRAC and VSC sys-
tems will not f unction correctly if 
different tires are installed on the 
vehicle.
Contact your Toyota dealer for fur-
ther information when replacing 
tires or wheels.
■Handling of tires and the sus-
pension
Using tires with any kind of prob-
lem or modifying the suspension 
will affect the driving assist sys-
tems, and may cause a system to 
malfunction.
■Secondary Collision Brake
Do not rely solely upon the Sec-
ondary Collision Brake. This sys-
tem is designed to help reduce 
the possibility of  further damage 
due to a secondary collision, how-
ever, that effect changes accord-
ing to various conditions. Overly 
relying on the system may result 
in death or serious injury.

2824-6. Driving tips
When driving your vehicle 
off-road, please observe the fol-
lowing precautions to ensure 
your driving enjoyment and to 
help prevent the closure of 
areas to off-road vehicles:
Drive your vehicle only in 
areas where off-road vehicles 
are permitted to travel.
 Respect private property. Get 
owner’s permission before 
entering private property.
 Do not enter areas that are 
closed. Honor gates, barriers 
and signs that restrict travel.
 Stay on established roads. 
When conditions are wet, 
driving techniques should be 
changed or travel delayed to 
prevent damage to roads.

■Off-road driving precautions
Always observe t he following pre-
cautions to minim ize the risk of 
death, serious injury or damage to 
your vehicle:
●Drive carefully when off the 
road. Do not take  unnecessary 
risks by driving in dangerous 
places.
●Do not grip the steering wheel 
spokes when driving off-road. A 
bad bump could jerk the wheel 
and injure your hands. Keep 
both hands and especially your 
thumbs on the ou tside of the 
rim.
●Always check your brakes for 
effectiveness immediately after 
driving in sand, mud, water or 
snow.
●After driving through tall grass, 
mud, rock, sand, rivers, etc., 
check that there  is no grass, 
bush, paper, rags, stone, sand, 
etc. adhering or trapped on the 
underbody. Clear off any such 
matter from the underbody. If 
the vehicle is used with these 
materials trapped or adhering to 
the underbody, a breakdown or 
fire could occur.
●When driving off-road or in rug-
ged terrain, do not drive at 
excessive speeds, jump, make 
sharp turns, strike objects, etc. 
This may cause loss of control 
or vehicle rollover causing 
death or serious injury. You are 
also risking expensive damage 
to your vehicle’s suspension 
and chassis.
