2022 LEXUS ES300h parking sensors

2404-5. Using the driving support systems
QParking Support Brake function
(rear pedestrians) (if equipped)
A rear camera sensor is used to detect
pedestrians in the detection area
behind the vehicle when backing up.
(  P.251)
WARNING
QCautions regarding the use of the
system
Do not overly rely on the system, as
doing so may lead to an accident.
Always drive while checking the safety of
the surroundings of the vehicle.
Depending on the vehicle and road con-
ditions, weather, etc., the system may not
operate.
The detection capabilities of sensors and
radars are limited. Always drive while
checking the safety of the surroundings
of the vehicle.
OThe driver is solely responsible for safe
driving. Always drive carefully, taking
care to observe your surroundings.
The Parking Support Brake system is
designed to provide support to lessen
the severity of collisions. However, it
may not operate in some situations.
OThe Parking Support Brake system is
not designed to stop the vehicle com-
pletely. Additionally, even if the system
has stopped the vehicle, it is necessary
to depress the brake pedal immedi-
ately as brake control will be canceled
after approximately 2 seconds.
OIt is extremely dangerous to check the
system operations by intentionally
driving the vehicle in to the direction of
a wall, etc. Never attempt such actions.
QWhen to disable the Parking Support
Brake
In the following situations, disable the
Parking Support Brake as the system
may operate even though there is no
possibility of a collision.
OWhen inspecting the vehicle using a
chassis roller, chassis dynamo or free
roller.
OWhen loading the vehicle onto a boat,
truck or other transport vessel.
OIf the suspension has been modified or
tires of a size other than specified are
installed.
OIf the front of the vehicle is raised or
lowered due to the carried load.
OWhen 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.
OWhen using automatic car washing
devices.
OIf the vehicle cannot be driven in a sta-
ble manner, such as when the vehicle
has been in an accident or is malfunc-
tioning.
OWhen the vehicle is driven in a sporty
manner or off-road.
OWhen the tires are not properly
inflated.
OWhen the tires are very worn.
OWhen tire chains, a compact spare tire
or an emergency tire puncture repair
kit are used.

Time
Hybrid system output restriction control begins operating
System determines that possibility of collision with detected object is high
Hybrid system output reduced
System determines that possibility of collision with detected object is extremely
high
Brake control begins operating
Brake control strength increased
Example: Multi-information display: “BRAKE!”
Example: Multi-information display: “Switch to Brake”
QIf the Parking Support Brake has oper-
ated
If the vehicle is stopped due to operation of
the Parking Support Brake, the Parking
Support Brake will be disabled and the
PKSB OFF indicator will illuminate. If the
Parking Support Brake operates unneces-
sarily, brake control can be canceled by
depressing the brake pedal or waiting for
approximately 2 seconds for it to automati-
cally be canceled. Then, the vehicle can be
operated by depressing the accelerator
pedal.
QRe-enabling the Parking Support Brake
To re-enable the Parking Support Brake
when it has been disabled due to system
operation, perform any of the following
operations. At this time, the PKSB OFF
indicator will turn off. ( P.74)
OTurn the PKSB system on ( P.241)
OTurn the power switch off, and then back
to ON mode
OShift the shift lever to P
ODrive with no operation targets in the
traveling direction of the vehicle
OChange the traveling direction of the
vehicle*
*
: Except the Parking Support Brake func- tion (rear pedestrian)
QIf “Parking Support Brake Unavailable”
is displayed on the multi-information
display and the PKSB OFF indicator is
flashing
If this message is displayed only when the
shift lever is in R, the rear camera lens may
be dirty. Clean the camera lens. If this mes-
sage is displayed when the shift lever is in
any position other than R, a sensor on the
front or rear bumper may be dirty. Clean
the sensors and their surrounding area on
the bumpers.
QIf “Parking Support Brake Unavailable”
and “Parking Assist Unavailable Clean
Parking Assist Sensor” are displayed on
the multi-information display and the
PKSB OFF indicator is flashing
OA sensor may be covered with ice, snow,
dirt, etc. In this case, remove the ice,
snow, dirt, etc., from the sensor to return
the system to normal. If this message is
shown even after removing dirt from the
sensor, or shown when the sensor was
not dirty to begin with, have the vehicle
inspected at your Lexus dealer.
OA sensor may be frozen. Once the ice
melts, the system will return to normal.
OWater 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.

2464-5. Using the driving support systems
*: If equipped
This function will operate in situations such as the following if an object is detected
in the traveling direction of the vehicle.
QWhen traveling at a low speed and the brake pedal is not depressed, or is
depressed late
Parking Support Brake function (static objects)*
If the sensors detect a static object, such as a wall, in the traveling direction of
the vehicle and the system determines that a collision may occur due to the
vehicle suddenly moving forward due to an accidental accelerator pedal oper-
ation, the vehicle moving the unintended direction due to the wrong shift posi-
tion being selected, or while parking or traveling at low speeds, the system will
operate to lessen the impact with the de tected static object and reduce the
resulting damage.

tions are met:
OHybrid system output restriction control
• The Parking Support Brake is enabled.
• The vehicle speed is approximately 9
mph (15 km/h) or less.
• Vehicles are approaching from the right or left at the rear of the vehicle at a travel-
ing speed of approximately 5 mph (8
Parking Support Brake function (rear-crossing vehicles)*
If a rear radar sensor detects a vehicle approaching from the right or left at the
rear of the vehicle and the system determines that the possibility of a collision
is high, this function will perform brake control to reduce the likelihood of an
impact with the approaching vehicle.
