Parking Support Brake

Purpose of the PKSB (Parking Support Brake) system

The PKSB (Parking Support Brake) system consists of the following functions that
operate when driving at a low speed or backing up, such as when parking. When
the system determines that the probability of a collision with a detected object is
high, a warning operates to urge the driver to take evasive action.

■

Parking assist function

The system can detect the following as detectable objects. (Detectable objects
differ depending on the function.)

●

Static Objects Front and Rear of the vehicle

●

Moving Vehicles Rear of the Vehicle

●

Pedestrians Rear of the Vehicle

PKSB (Parking Support Brake) system

WARNING

■

Cautions 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 conditions, 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.

●

The driver is solely responsible for safe driving. Always drive carefully, taking care to
observe your surroundings. The PKSB (Parking Support Brake) system is designed
to provide support to lessen the severity of collisions. However, it may not operate in
some situations.

●

The PKSB (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 immediately as brake control will be canceled after approxi-
mately 2 seconds.

●

It is extremely dangerous to check the system operations by intentionally driving the
vehicle into the direction of a wall, etc. Never attempt such actions.

■

When to disable the PKSB (Parking Support Brake) system

In the following situations, disable the PKSB (Parking Support Brake) as the system may
operate even though there is no possibility of a collision.

■

Precautions for the suspension

Do not modify the suspension of the vehicle. If the height or tilt of the vehicle is changed,
the sensors may not be able to detect detectable objects and the system may not operate
correctly, possibly leading to an accident.

■

System overview

If the PKSB (Parking Support Brake) determines that a collision with a detected
object or pedestrian is possible, the engine output will be restricted to restrain
any increase in the vehicle speed. (Engine 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 control: See figure 3.)

When the vehicle is subjected to a severe frontal or side impact or rollover, the
pretensioners retract the seat belts of the front seats and rear outer seats to
securely restrain the occupants.

The pretensioners will not operate in minor frontal or side impacts, or rear impacts.

INFORMATION

■

Replacing the belt after the pretensioner has been activated

If the vehicle is involved in multiple collisions, the pretensioner will activate for the first
collision, but will not activate for the second or subsequent collisions.

■

PCS-linked control

If the PCS (Pre-Collision System) determines that the possibility of a collision with a
vehicle is high, the seat belt pretensioners will be prepared to operate.

WARNING

■

Seat belt pretensioners

Observe the following precautions to reduce the risk of injury in the event of sudden
braking or an accident. Failure to do so may result in death or serious injury.

●

Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor from detect-
ing the passenger’s weight properly. As a result, the seat belt pretensioner for the front
passenger’s seat may not operate in the event of a collision.

●

If a pretensioner has operated, the SRS warning light will illuminate.
In this situation, the seat belt cannot be used and must be replaced by your Lexus
dealer.

SRS airbags

The SRS airbags deploy when the vehicle is subjected to certain types of severe
impact that may cause significant injury to the occupants. The airbags work togeth-
er with the seat belts to help reduce the risk of death or serious injury.

Your vehicle is equipped with ADVANCED AIRBAGS designed based on US
motor vehicle safety standards (FMVSS208). The airbag sensor assembly (ECU)
controls airbag deployment based on information obtained from the sensors, etc.,

shown in the system components diagram above. This information includes crash
severity and occupant information. As the airbags deploy, a chemical reaction in
the inflators quickly fills the airbags with non-toxic gas to help restrain the motion of
the occupants.

INFORMATION

■

If the SRS airbags deploy (inflate)

●

Slight abrasions, burns, bruising, etc., may be sustained from SRS airbags, due to the
extremely high speed of deployment (inflation) by hot gases.

●

A loud noise and white powder will be emitted.

●

Parts of the airbag module (steering wheel hub, airbag cover and inflator) as well as
the parts around the airbags may be hot for several minutes. The airbag itself may also
be hot.

●

The windshield may crack.

●

All of the doors will be unlocked.

●

The brakes and stop lights will be controlled automatically.

●

The interior lights will turn on automatically.

●

The emergency flashers will turn on automatically.

●

Fuel supply to the engine will be stopped.

●

For Safety Connect subscribers, if any of the following situations occur, the system is
designed to send an emergency call to the response center, notifying them of the vehi-
cle's location (without needing to push the [SOS] button) and an agent will attempt to
speak with the occupants to ascertain the level of emergency and assistance required.
If the occupants are unable to communicate, the agent automatically treats the call as
an emergency and helps to dispatch the necessary emergency services.

SRS airbag precautions

Observe the following precautions. Failure to do so may result in death or serious injury.

●

The driver and all passengers must wear their seat belts correctly.
The SRS airbags are supplemental devices to be used with the seat belts.

●

The SRS driver airbag deploys with considerable force, and can cause death or
serious injury, especially if the driver is very close to the airbag. The National Highway
Traffic Safety Administration (NHTSA) advises:
Since the risk zone for the driver’s airbag is the first 2 - 3 in. (50 - 75 mm) of inflation,
placing yourself 10 in. (250 mm) from your driver airbag provides you with a clear

WARNING

margin of safety. This distance is measured from the center of the steering wheel to
your breastbone. If your current driving position places you less than 10 in. (250 mm)
away from the driver airbag, you can change your driving position in several ways:

•

Move your seat to the rear as far as possible while still being able to reach the
pedals comfortably.

•

Slightly recline the seatback. Although vehicle designs vary, many drivers can
achieve the 10 in. (251 mm) distance, even with the driver seat all the way forward,
simply by reclining the seatback somewhat. If reclining the seatback makes it hard
to see the road, raise yourself by using a firm, non-slippery cushion, or raise the seat
if your vehicle has that feature.

•

If your steering wheel is adjustable, tilt it downward. This points the airbag toward
your chest instead of your head and neck. The seat should be adjusted as recom-
mended by the NHTSA, while still being able to control the vehicle with the pedals
and steering wheel, and maintaining your view of the instrument panel controls.

●

If a seat belt extender has been connected to a
front seat belt buckle but the latch plate of the seat
belt has not been fastened to the seat belt extend-
er, the SRS airbag system will judge that the occu-
pant is wearing the seat belt even though the seat
belt has not been fastened. In this case, the SRS
front airbags may not deploy correctly in a colli-
sion, resulting in death or serious injury. Be sure to
wear the seat belt correctly when using a seat belt
extender.

●

The SRS front passenger airbag deploys with considerable force, and can cause death
or serious injury, especially if the front passenger is very close to the airbag. The front
passenger seat should be positioned as far possible from the airbag with the seatback
adjusted so that the passenger is sat upright.

●

Improperly seated and/or restrained infants and children can be killed or seriously
injured by a deploying airbag. An infant or child who is too small to use a seat belt
should be properly secured using a child restraint system. Lexus strongly recommends
that all infants and children be placed in the rear seats of the vehicle and properly
restrained. The rear seats are safer for infants and children than the front passenger
seat.

WARNING

●

Do not sit on the edge of the seat or lean against
the dashboard.

●

Do not allow a child to stand in front of the SRS
front passenger airbag or sit on the lap of a front
passenger.

●

Front seat occupants should never hold items on
their lap.

●

Do not lean against the door, roof side rail, or front,
side, or rear pillar.

●

Do not allow anyone to kneel on a seat toward the
door or put their head or hands outside the vehi-
cle.

●

Do not attach anything to or lean anything against
areas such as the dashboard, steering wheel pad
and lower portion of the instrument panel.

WARNING

●

Do not attach anything to areas such as the doors,
windshield, side windows, front or rear pillars, roof
side rails and assist grips.(With the exception of
the speed limit label

）

●

Do not hang coat hangers or other hard objects on the coat hooks. These items could
become projectiles if the SRS curtain shield airbags deploy, possibly leading to death
or serious injury.

●

If a vinyl cover is attached to the area where the SRS knee airbag deploys, be sure to
remove it.

●

Do not use seat accessories which cover the parts from which the SRS airbags deploy,
as they may interfere with inflation of the SRS airbags. Such accessories may prevent
the SRS airbags from deploying correctly, may disable the system or cause the SRS
airbags to inflate unintentionally, possibly resulting in death or serious injury.

●

Do not strike or apply significant force to the SRS airbag system components, front
doors or their surrounding area. Doing so may cause the SRS airbags to malfunction.

●

Do not touch any components of the SRS airbags immediately after the SRS airbags
have deployed (inflated) as they may be hot.

●

If breathing becomes difficult after the SRS airbags have deployed, open a door or
window to allow fresh air in, or leave the vehicle if it is safe to do so. Wash off any
residue as soon as possible to prevent skin irritation.

●

If a part where an SRS airbag is stored is damaged or cracked, have it replaced by
your Lexus dealer.

●

Do not place anything, such as a cushion, on the front passenger's seat. Doing so
will disperse the passenger’s weight, which prevents the sensor from detecting the
passenger’s weight properly. As a result, the SRS front airbags for the front passenger’s
seat may not deploy in the event of a collision.
