BSM (Blind Spot Moni-
tor)*
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 o bserve your sur-
roundings.
The Blind Spot Monitor is a sup-
plementary function which alerts
the driver that a v ehicle 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.

●Initialization may not have been
performed after a battery terminal
was disconnected and recon-
nected. Initialize the system.
(  P.287) If this message contin-
ues to be displayed even after ini-
tialization, have the vehicle
inspected by you r Toyota dealer.
■If “Parking Assist Unavailable
Clean Parking Assist Sensor” is
displayed on the multi-informa-
tion display
A sensor may be covered with ice,
snow, dirt, etc. Remove the ice,
snow, dirt, etc., from the sensor to
return the syste m to normal.
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 battery terminal has been
disconnected and reconnected
The system needs to be initialized.
To initialize the system, drive the
vehicle straight ahead for 5 seconds
or more at a speed of approximately
22 mph (35 km/h) or more.
■Sensor detection information
●The following situations may occur
during use.
• The sensor's detection areas are limited to the areas around the
vehicle front and rear bumpers.
• Depending on the shape of the object and other factors, the
detection distance may shorten, or
detection may be impossible.
• If an object is extremely close to a sensor, it may not be detected.
• There will be a short delay
between object detection and dis-
play. Even at low speeds, there is
a possibility that the object will
come within the sensor’s detec-
tion areas before the display is
shown and the warning 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 diffi cult 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 attent ion 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 cloth-
ing.
■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.

por t Brake)*
The Parking Support Brake
system 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.

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 Parking
Support Brake system is
designed to provide support to
lessen the severity of collisions.
However, it may not operate in
some situations.
●The Parking Support Brake sys-
tem 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 imme-
diately as brake control will be
canceled after approximately 2
seconds.

■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.
■Trailer Sway Control
Helps the driver to control trailer
sway by selectively applying
brake pressure for individual
wheels and reducing driving
torque when trailer sway is
detected.
■TRAC (Traction Control)
Helps to maintain drive power
and prevent the drive wheels
from spinning when starting the

tions may be generated, but this is
not a malfunction.
■EPS operation sound
When the steering wheel is oper-
ated, a motor sound (whirring
sound) may be heard. This does not
indicate a malfunction.
■Reduced effectiveness of the
EPS system
The effectiveness of the EPS sys-
tem is reduced to prevent the sys-
tem from overheating when there is
frequent steering input over an
extended period of time. The steer-
ing wheel may feel heavy as a
result. Should this occur, refrain
from excessive steering input or
stop the vehicle and turn the engine
off. The EPS syst em should return
to normal within 10 minutes.
