■Hands off steering wheel warn-
ing
In the following situations, a warning
message urging the driver to hold
the steering wheel and the symbol
shown in the illust ration are dis-
played on the multi-information dis-
play to warn the driver. The warning
stops when the sys tem determines
that the driver holds the steering
wheel. Always keep your hands on
the steering wheel when using this
system, regardless of warnings.
●When the system determines the
driver is not hold ing the steering
wheel while the lane centering
function is operating.
If the driver continues to keep their
hands off of the steering wheel, the
buzzer sounds, the driver is warned
and the function is temporarily can-
celed. This warning also operates in
the same way when the driver con-
tinuously operates the steering
wheel only a s mall amount.
●When the system determines that
the vehicle may deviate from the
lane while driving around a curve
while the lane centering function is
operating.

●Initialization may not have been
performed after a battery terminal
was disconnected and recon-
nected. Initialize the system.
( P.295) 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 12-volt batte ry terminal has
been disconnected and recon-
nected
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.

The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect objects that
are extremely clos
e to the vehicle.
The range of the sensors may
change depending on the shape of
the object, etc.
■Multi-information display, head-up display (if equipped) and
audio system screen
When an object is detected by a sensor, the approximate distanc e to
the object will be displayed on th e multi-information display, audio
system screen, and head-up display (if equipped). (As the dista nce
to the object becomes short, the distance segments may blink.)

■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
1.0 ft. (30 cm) of the object,
the buzzer sounds continu-
ously.
When 2 or more objects are
detected simultaneously, the
buzzer sounds for the nearest
object. If one or more objects
come within approximately
1.0 ft. (30 cm) of the vehicle,
the buzzer will repeat a long
tone, followed by fast beeps.
Automatic buzzer mute func-
tion: After a buzzer begins
sounding, if the distance
between the vehicle and the
detected object does not
become shorter, the buzzer
will be muted automatically.
(However, if the distance
between the vehicle and
object is 1.0 ft. (30 cm) or
less, this function will not operate.)
The buzzer sounds volume can
be adjusted. ( P.297)
