5-4. Using the driving support systems
Driving
■The system can be operated when
●The power switch is in ON.
●Toyota parking assist-sensor function is on.
●The vehicle speed is less than about 10 km/h (6 mph).
●A shift position other than P is selected.
■Sensor detection information
●The sensor’s detection areas are lim-ited 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 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 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 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
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
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 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, water drops 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.
●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 detec-tors, motorcycle engines, air brakes of large vehicles, the clearance sonar of
other vehicles or other devices which produce ultrasonic waves are near the vehicle
●A sensor is coated with a sheet of spray or heavy rain.
●If objects draw too close to the sensor.
WARNING
●When using steam to clean the vehicle, do not direct steam too
close to the sensors as doing so may cause a sensor to malfunction.

5-4. Using the driving support systems
●When a pedestrian is wearing clothing
that does not reflect ultrasonic waves (ex. skirts with gathers or frills).
●When objects that are not perpendicu-lar to the ground, not perpendicular 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, motor-cycle, 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 protector (an addi-
tional 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 a tire chains, compact spare tire
or an emergency tire puncture repair kit is used
■Situations in which the system may operate even if there is no possibil-
ity of a collision
In some situations, such as the follow- ing, the system may operate even
though there is no possibility of a colli- sion.
●When driving on a narrow road
●When driving toward a banner, flag,
low-hanging branch or boom barrier (such as those used at railroad cross-ings, toll gates and parking lots)
●When there is a rut or hole in the sur-face of the road
●When driving on a metal cover (grat-ing), 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 detec-tors, motorcycle engines, air brakes of large vehicles, the clearance sonar of
other vehicles or other devices which produce ultrasonic waves are near the vehicle
●If the front of the vehicle is raised or lowered due to the carried load

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 probabil-
ity of a collision with a
detected object or pedestrian
is high, a warning operates to
urge the driver to take evasive
action. If the s ystem deter-
mines that the possibility of a
collision with a detected object
or pedestrian is extremely
high, the brakes are automati-
cally applied to help avoid the
collision or help reduce the
impact of the collision.

If the Parking Support Brake deter-
mines that a collision with a
detected object or pedestrian is
possible, the EV system output will
be restricted to restrain any
increase in the vehicle speed. (EV
system output restriction control:
See figure 2.)
Additionally, if the accelerator pedal
continues to be depressed, the
brakes will be applied automatically
to reduce the vehicle speed. (Brake

such as on snow.
System operation
X-MODE*
This mode has improved road
handling ability off roads.
Select between the 2 types of
mode, SNOW/DIRT and
D.SNOW/MUD.
During “X-MODE”, the down-
hill assist control will control
the brakes to maintain a con-
stant vehicle speed when driv-
ing on steep descents.
Grip Control supports the
driver’s operation by maintain-
ing a low vehicle speed on
steep inclines and slippery
roads without having to step
on the accelerator pedal or
brake pedal.
WARNING
■Be sure to observe the following
before using “X-MODE”
If not observed, there is the danger that it may lead to an unexpected
accident.
●Drive the vehicle after checking that
the SNOW/DIRT indica- tor/D.SNOW/MUD indicator turns on.
●“X-MODE” is not a device that enhances the limited performance
of the vehicle. Carefully check the road surface conditions and the driving route in advance, and then
drive with caution.
