■The Parking Support Brake func- tion (static object) will operate
when
The function will operate when the PKSB OFF indicator is not illuminated
( P.170, 171) and all of the following conditions are met:
●Hybrid system output restriction con-trol
• The Parking Support Brake is enabled.• The vehicle speed is approximately 15
km/h (9 mph) or less. • There is a static object in the traveling direction of the vehicle and approxi-
mately 2 to 4 m (6 to 13 ft.) away. • The Parking Support Brake deter-mines that a stronger-than-normal
brake operation is necessary to avoid a collision.
●Brake control• Hybrid system output restriction con-
WARNING
●If the area around a radar sensor is subjected to an impact, the system
may not operate properly due to a sensor malfunction. Have the vehi-cle inspected by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■Handling the suspension
Do not modify the suspension, as changes to the height or inclination of
the vehicle may prevent the sensors from detecting objects correctly or cause the system to not operate or
operate unnecessarily.
■If the Parking Support Brake
function (static objects) operates unnecessarily, such as at a rail-road crossing
In the event that the Parking Support Brake function (static objects) oper-ates unnecessarily, such as at a rail-
road crossing, brake control will be canceled after approximately 2 sec-onds, allowing you to proceed forward
and leave the area, brake control can also be canceled by depressing the brake pedal. Depressing the acceler-
ator pedal after brake control is can- celed will allow you to proceed forward and leave the area.
■Notes when washing the vehicle
Do not apply intensive bursts of water
or steam to the sensor area.
Doing so may result in the sensor malfunctioning.
●When using a high pressure washer to wash the vehicle, do not
spray the sensors directly, as doing so may cause a sensor to malfunc-tion.
●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.
■When to disable the Parking Sup-port Brake
In the following situations, disable the
Parking Support Brake as the system may operate even though there is no possibility of a collision.
●When inspecting the vehicle using a chassis roller, chassis dynamo or
free roller
●When loading the vehicle onto a
boat, truck or other transport vessel
●If the suspension has been modi-
fied or tires of a size other than specified are installed
●If the front of the vehicle is raised or lowered due to the carried load
●When equipment that may obstruct a sensor is installed, such as a tow-ing eyelet, bumper protector (an
additional trim strip, etc.), bicycle carrier, or snow plow
●When using an automatic car wash

5 5-5. Using the driving support systems
Driving
• When strong winds are blowing
• If a sensor is covered with ice, snow,
dirt, etc. (when cleared, the system
will return to normal)
• If heavy rain or water strikes a sensor
• When driving in inclement weather
such as fog, snow or a sandstorm
• A sensor is frozen. (Thawing the area
will resolve this problem.)
●Vehicle surroundings
• 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
• The vehicle is approaching a tall or
curved curb.
• On an extremely bumpy road, on an
incline, on gravel, or on grass.
• The objects draw too close to the sen-
sor.
●Other sonic waves sources
• 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 a sticker or an electronic compo-
nent, such as a backlit license plate
(especially fluorescent type), fog lights, fender pole or wireless antenna
is installed near a sensor
●Changes in the vehicle
• If the vehicle is significantly tilted
• If the front of the vehicle is raised or
lowered due to the carried load
• 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 suspension has been modified
or tires of a size other than specified
are installed
• If paint or a sticker is applied to the
sensor

approximately 24 km/h (15 mph)
*: Depending on the conditions, detec-
tion of a vehicle and/or object may
occur.
■Situations in which the system may
operate even though there is no
possibility of a collision
In some situations such as the following,
the Parking Support Brake function
(rear-crossing vehicles) may operate
even though there is no possibility of a
collision.
●When the parking space faces a
street and vehicles are being driven
on the street
●When a detected vehicle turns while
approaching the vehicle
●When a vehicle passes by the side of
your vehicle
●When the distance between your vehi-
cle and metal objects, such as a
guardrail, wall, sign, or parked vehicle, which may reflect electrical waves
toward the rear of the vehicle, is short
●When there are spinning objects near
your vehicle such as the fan of an air
conditioning unit
●When water is splashed or sprayed
toward the rear bumper, such as from
a sprinkler
■Situations in which the Parking
Support Brake function (rear-cross-
ing vehicles) may not operate prop-
erly
In some situations, such as the follow-
ing, the radar sensors may not detect an
object and this function may not operate
properly
●Stationary objects
●When a sensor or the area around a
sensor is extremely hot or cold
●If the rear bumper is covered with ice,
snow, dirt, etc.
●When it is raining heavily or water
strikes the vehicle
●When the detection area of a radar
sensor is obstructed by an adjacent
vehicle
●If the vehicle is significantly tilted
●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 suspension has been modified
or tires of a size other than specified
are installed
●If the front of the vehicle is raised or
lowered due to the carried load
●If a sticker or an electronic compo-

should be placed so that the vehicle is
balanced.
When replacing wheels, care
should be taken to ensure that they
are equivalent to those removed in
load capacity, diameter, rim width
and inset*.
Replacement wheels are available
at any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
*: Conventionally referred to as offset.
Toyota does not recommend using
the following:
Wheels of different sizes or types
Used wheels
Bent wheels that have been
straightened
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves and
transmitters that allow the tire pressure warning system to provide advance warning in the event of a loss in tire
inflation pressure. Whenever wheels are replaced, tire pressure warning valves and transmitters must be installed.
( P.511, 531)
WARNING
■Proper inflation is critical to save tire performance
Keep your tires properly inflated. If the tires are not properly inflated, the following conditions may occur
which could lead to an accident resulting in death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting
from overheated tires
●Air leaking from between tire and
wheel
●Wheel deformation and/or tire dam-
age
●Greater possibility of tire damage
while driving (due to road hazards, expansion joints, sharp edges in the road, etc.)
NOTICE
■When inspecting and adjusting
tire inflation pressure
Be sure to put the tire valve caps back on.
If a valve cap is not installed, dirt or moisture may get into the valve and cause an air leak, resulting in
decreased tire inflation pressure.
Wheels
If a wheel is bent, cracked or
heavily corroded, it should be
replaced. Otherwise, the tire
may separate from the wheel
or cause a loss of handling
control.
