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.

Driving
*: If equipped
The system can detect the fol-
lowing as detectable objects.
(Detectable objects differ
depending on the function.)

of the vehicle ( P.270)
 Moving Vehicles Rear of the
Vehicle ( P.272)
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.

carried load
●When equipment that may
obstruct a sensor is installed,
such as a towing eyelet, bumper
protector (an additional trim
strip, etc.), bicycle carrier, or
snow plow
●When using automatic car
washing devices
●If the vehicle cannot be driven in
a stable manner, such as when
the vehicle has been in an acci-
dent or is malfunctioning
●When the vehicle is driven in a
sporty manner or off-road
●When the tires are not properly
inflated
●When the tires are very worn
●When a tire chains or compact
spare tire is used
●When your vehicle is towing a
trailer or during emergency tow-
ing
■Precautions for the suspen-
sion
Do not modify the suspension of
the vehicle. If the height or tilt of
the vehicle is c hanged, the sen-
sors may not be able to detect

■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

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.
