Initialization may not have been
performed after a battery terminal
was disconnected and recon-
nected. Initialize the system.
(
If this message continues to be
displayed even after initialization,
have the vehicle inspected by
your Toyota dealer.
■
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 sensor’s detection areas are
limited to the areas around the
vehicle’s 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.
• There will be a short delay
between static object detection
and display (warning buzzer
sounds). Even at low speeds,
there is a possibility that the object
will come within 11.9 in. (30 cm)
before the display is shown and
the warning buzzer 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
sound of this system due to the
buzzers of other systems.
■
Objects which the system may
not properly detect
The shape of the object may pre-
vent the sensor from detecting it.
Pay particular attention to the fol-
lowing 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. Particular instances
where this may occur are listed
below.
●
There is dirt, snow or ice on a sen-
sor. (Cleaning the sensors will
resolve this problem.)
●
A sensor is frozen. (Thawing the
area will resolve this problem.)
In especially cold weather, if a
sensor is frozen the sensor dis-
play may be displayed abnor-
mally, 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 other vehicles or
other devices which produce ultra-
sonic waves are near the vehicle.
274
4-5. Using the driving support systems
●
A sensor is coated with a sheet of
spray or heavy rain.
●
If objects draw too close to the
sensor.
●
When a pedestrian is wearing
clothing that does not reflect ultra-
sonic waves (ex. skirts with gath-
ers or frills).
●
When objects that are not perpen-
dicular to the ground, not perpen-
dicular to the vehicle traveling
direction, uneven, or waving are in
the detection range.
●
Strong wind is blowing.
●
When driving in inclement weather
such as fog, snow or a sandstorm.
●
When an object that cannot be
detected is between the vehicle
and a detected object.
●
If an object such as a vehicle,
motorcycle, bicycle or pedestrian
cuts in front of the vehicle or runs
out from the side of the vehicle.
●
If the orientation of a sensor has
been changed due to a collision or
other impact.
●
When equipment that may
obstruct a sensor is installed, such
as a towing eyelet, bumper pro-
tector (an additional trim strip,
etc.), bicycle carrier, or snow
plow.
●
If the front of the vehicle is raised
or lowered due to the carried load.
●
If the vehicle cannot be driven in a
stable manner, such as when the
vehicle has been in an accident or
is malfunctioning.
●
When tire chains, a compact
spare tire or an emergency tire
puncture repair kit are used.
■
Situations in which the system
may operate even if there is no
possibility of a collision
In some situations, such as the fol-
lowing, the system may operate
even though there is no possibility of
a collision.
●
When driving on a narrow road.
●
When driving toward a banner,
flag, low-hanging branch or boom
barrier (such as those used at rail-
road crossings, toll gates and
parking lots).
●
When there is a rut or hole in the
surface of the road.
●
When driving on a metal cover
(grating), such as those used for
drainage ditches.
●
When driving up or down a steep
slope.
●
If a sensor is hit by a large amount
of water, such as when driving on
a flooded road.
●
There is dirt, snow, water drops or
ice on a sensor. (Cleaning the
sensors will resolve this problem.)
●
A sensor is coated with a sheet of
spray or heavy rain.
●
When driving in inclement weather
such as fog, snow or a sandstorm.
●
When strong winds are blowing.
●
When vehicle horns, vehicle
detectors, motorcycle engines, air
brakes of large vehicles, the clear-
ance sonar of other vehicles or

Buzzer operation and dis-
tance to an object
A buzzer sounds when the sen-
sors are operating.
The buzzer beeps faster as
the vehicle approaches an
object.
When the vehicle comes
within approximately 1.1 ft.
(34 cm) of the object, the
buzzer sounds continuously.
When 2 or more sensors
simultaneously detect a static
object, the buzzer sounds for
the nearest object.
Even when the sensors are
operating, the buzzer will be
muted in some situations.
(automatic buzzer mute func-
tion)
■
Muting the buzzer sound
●
Automatic buzzer mute function
Even when the sensors are operat-
ing, the buzzer will be muted in the
following situations:
• The distance between the vehicle
and the detected object does not
become shorter (except when the
distance between the vehicle and
object is 1.1 ft. [34 cm] or less).
• Your vehicle is moving away from
the object.
• There are no detectable objects
entering the path of your vehicle.
However, if another object is
detected or the situation changes
while the buzzer is muted, the
buzzer begins sounding again.
●
To mute the buzzer sound
The buzzer can be temporarily
muted by pressing
of the meter
control switches while a suggestion
that says mute is available is shown
on the multi-information display.
●
When the mute is canceled
Mute will be automatically canceled
in the following situations.
• When the shift position is changed
• When the vehicle speed has
reached or exceeded a certain
speed
• When the Intuitive parking assist
is turned off once and turned on
again
• When the engine switch is turned
off once and turned to ON again
■
Customization
The buzzer volume can be adjusted
on the multi-information display.

*
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
collision.
PKSB (Parking Support
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 not operate.
The detection capabilities 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. Addition-
ally, even if the system has
stopped the vehicle, it is neces-
sary to depress the brake pedal
immediately as brake control
will be canceled after approxi-
mately 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.
■
When to disable the Parking
Support Brake
In the following situations, disable
the Parking Support Brake as the
system may operate even though
there is no possibility of a colli-
sion.

remove the ice, snow, dirt, etc.,
from the sensor to return the sys-
tem to normal. If this message is
shown even after removing dirt
from the sensor, or shown when
the sensor was not dirty to begin
with, have the vehicle inspected at
your Toyota dealer.
●
A sensor may be frozen. Once the
ice melts, the system will return to
normal.
●
Water may be continuously flow-
ing over the sensor surface, such
as in a heavy rain. When the sys-
tem determines that it is normal,
the system will return to normal.

The screen illustrations used in
this text are intended as exam-
ples, and may differ from the
image that is actually displayed on
the screen.
The rear view monitor system is
a supplemental device intended
to assist the driver when back-
ing up. When backing up, be
sure to visually check all around
the vehicle both directly and
using the mirrors before pro-
ceeding. If you do not, you may
hit another vehicle, and could
possibly cause an accident.
Pay attention to the following
precautions when using the rear
view monitor system.
Rear view monitor sys-
tem

The rear view monitor sys-
tem assists the driver by
displaying an image of the
view behind the vehicle with
fixed guide lines on the
screen while backing up, for
example while parking.
Driving precautions
WARNING
●
Never depend on the rear view
monitor system entirely when
backing up. The image and the
position of the guide lines dis-
played 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 traffic con-
ditions, road surface condi-
tions, vehicle condition, etc.
when parking. It is necessary to
be fully aware of this before
using the rear view monitor sys-
tem.
●
When parking, be sure to check
that the parking space will
accommodate your vehicle
before maneuvering into it.
●
