1 Pressing the cancel switch can-
cels the speed control.
The speed control is also canceled
when the brake pedal is depressed.
(When the vehicle has been stopped by
system control, depr essing the brake
pedal does not cancel the setting.)
2 Pressing the “+RES” switch
resumes the cruise control and
returns vehicle speed to the set
speed.
When your vehicle is too close to a
vehicle ahead, and sufficient auto-
matic deceleration via the cruise
control is not possible, the display
will flash and the buzzer will sound
to alert the driver. An example of
this would be if ano ther driver cuts
in front of you whi le you are follow-
ing a vehicle. Depress the brake
pedal to ensure an appropriate
vehicle-to-vehicle distance.

■Toyota parking assist-sensor
precautions
Observe the following precautions. Failing to do so may result in the vehi -
cle being unable to be driven safely
and possibly cause an accident.
●Do not use the sensor at speeds in
excess of 10 km/h (6 mph).
●The sensors’ detection areas and
reaction times are limited. When moving forward or reversing, check
the areas surrounding the vehicle
(especially the sides of the vehicle) for safety, and drive slowly, using
the brake to control the vehicle’s
speed.
●Do not install acce ssories near the
bumpers as those areas are within the sensors’ detection areas.

■If “Parking Assist Unavailable” is
displayed on the multi-information display (vehicles with PKSB)
Water may be continuously flowing over
the sensor surface, such as in a heavy rain. When the system determines that it
is normal, the system will return to nor-
mal.
■Sensor detection information
●The sensor’s detec tion areas are lim-
ited to the areas aro und the vehicle’s front and rear bumpers.
●The following situations may occur during use.
• Depending on the shape of the object
and other factors, t he detection dis- tance may shorten, or detection may
be impossible.
• Detection may be impossible if static objects draw too close to the sensor.
• There will be a shor t delay between
static object detec tion and display (warning buzzer sounds). Even at low
speeds, there is a possibility that the
object will come withi n 25 cm (9.8 in.) before the display is shown and the
warning buzzer sounds.
• It might be difficu lt 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 t o the buzzers of
other systems.
■Conditions under which the func -
tion may no t function correctly
Certain vehicle c onditions and the sur-
rounding 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 sensor.
(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 display may be displayed abnormally, or objects, such
as a wall, may not be detected.
●A sensor is covered in any way.
●When a sensor or the area around a sensor is extremely hot or cold.
●On an extremely bumpy road, on an incline, on grav el, or on grass.
●The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines,
air brakes of large vehicles, or other
loud noises pro ducing ultrasonic waves.
●There is another vehicle equipped with parking assist sensors in the
vicinity.
●A sensor is coated with a sheet of
spray or heavy rain.
●If a sensor is hit by a large amount of
water, such as when driving on a
flooded road.
●If the vehicle is significantly tilted.
●The vehicle is approaching a tall or
curved curb.
●If objects draw too close to the sensor.
■Objects which may not be properly
detected
The shape of the object may prevent the sensor from detecting it. Pay particular
attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that
absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections pro- jecting outwards in the direction of
your vehicle

some situations. (automatic
buzzer mute function)
■Muting the buzzer sound (vehicles
with PKSB)
●Automatic buzzer mute function
Even when the sensor s are operating,
the buzzer will be muted in the following
situations:
• The distance between the vehicle and the detected objec t does not become
shorter (except when the distance
between the vehicle and object is 30 cm [1.0 ft.] or less).
• Your vehicle is moving away from the
object. • There are no detec table objects enter-
ing 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 automatic ally canceled in
the following situations.
• When the shift position is changed • When the vehicle s peed has reached
or exceeded a certain speed
• When the Toyota par king assist is turned off once and turned on again
• When the power switch is turned off
once and turned to ON again
■Customization
The buzzer volume can be adjusted on
the multi-information display. (except for
vehicles without front sensors) ( →P.186)

PKSB (Parking Support
Brake)*
The Parking Support Brake
system consists of the follow -
ing functions that operate
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 oper-
ates to urge the driver to take
evasive action. If the system
determines that the possibility
of a collision with a detected
object is extrem ely high, the
brakes are automatically
applied to help avoid the colli -
sion or help red uce the impact
of the collision.
