INFORMATION

■

Situations in which the curve speed reduction function may not operate

In situations such as the following, the curve speed reduction function may not operate:

●

When the vehicle is being driven around a gentle curve

●

When the accelerator pedal is being depressed

●

When the vehicle is being driven around an extremely short curve

Support for lane change

If your vehicle is being driven at approximately 50 mph (80 km/h) or more and
a lane change to the passing lane is performed, when the turn signal lever is
operated and the lane is changed, the vehicle will accelerate up to the set speed to
assist in overtaking.

The system’s recognition of which lane is the passing lane may be based solely on the
location of the steering wheel in the vehicle (left-hand drive/right-hand drive). If the vehicle
is driven in a location where the passing lane is on the opposite side of that where
the vehicle was originally sold, the vehicle may accelerate when the turn signal lever is
operated away from the passing lane. (e.g. The vehicle was manufactured for a right-hand
traffic location, but is being driven in a left-hand traffic location. The vehicle may accelerate
when the turn signal lever is operated to the right.)
If your vehicle is being driven at approximately 50 mph (80 km/h) or more and the lane is
changed to that with a vehicle traveling slower than your vehicle, when the turn signal lever
is operated the vehicle will gradually decelerate to assist in changing lanes.

Emergency Driving Stop System

The emergency driving stop system is a system which automatically decelerates
and stops the vehicle within its lane if the driver becomes unable to continue
driving the vehicle, such as if they have suffered a medical emergency, etc.
During LTA (Lane Tracing Assist) control, if the system does not detect driving
operations, such as if the driver is not holding the steering wheel, and determines
the driver is not responsive, the vehicle will be decelerated and stopped within its
current lane to help avoid a collision or reduce the impact of a collision.

WARNING

■

For safe use

●

Driving safely is solely the responsibility of the driver. Pay careful attention to the
surrounding conditions in order to ensure safe driving. The emergency driving stop
system is designed to provide support in an emergency where it is difficult for the
driver to continue driving, such as if they have had a medical emergency. It is not
designed to support driving while drowsy or in poor physical health, or inattentive
driving.

●

Although the emergency driving stop system is designed to decelerate the vehicle
within its lane to help avoid or help reduce the impact of a collision if the system
determines that it is difficult for the driver to continue driving, its effectiveness may
change according to various conditions. Therefore, it may not always be able to
achieve the same level of performance. Also, if the operating conditions are not met,
this function will not operate.

●

After the emergency driving stop system operates, if driving becomes possible again,
immediately begin driving again or, if necessary, park the vehicle on the shoulder of
the road and set a warning reflector and flare to warn other drivers of your stopped
vehicle.

●

After this system operates, passengers should attend to the driver as necessary and
take appropriate hazard prevention measures, such as moving to a place where safety
can be ensured, such as the shoulder of the road or behind a guardrail.

●

This system detects the condition of the driver through the operation of the steering
wheel. This system may operate if the driver is aware but intentionally and continuously
does not operate the vehicle. Also, the system may not operate if it cannot determine
that the driver is not responsive, such as if they are leaning on the steering wheel.

6-2. Using the safe driving support functions

450

Summary of the system

Operation of this system is separated into 4 control states. Through control state
"warning phase 1" and "warning phase 2", the system determines if the driver
is aware and responsive while outputting a warning and controlling the vehicle
speed. If the system determines the driver is not responsive, it will operate in
control state "deceleration stop phase" and "stop hold phase" and decelerate and
stop the vehicle. It will then operate continuously in "stop hold phase".

INFORMATION

■

Operating conditions

This system operates when all of the following conditions are met:

●

When the LTA is on

●

When the vehicle speed is approximately 30 mph (50 km/h) or more

LTA control when operation is canceled

When emergency driving stop system operation is canceled, LTA control may also be
canceled.

Warning phase 1

If driving operations are not detected after the hands off steering wheel warning
operates, a buzzer will sound intermittently and a message will be displayed to
warn the driver, and the system will judge if the driver is responsive or not. If driving
operations, such as holding the steering wheel, are not performed within a certain
amount of time, the system will enter warning phase 2.

Warning phase 2

After entering warning phase 2, a buzzer will sound in short intervals and a
message will be displayed to warn the driver, and the vehicle will slowly decelerate.

Driving suppor

t s

ystem

If driving operations, such as holding the steering wheel, are not performed within
a certain amount of time, the system will determine that the driver is not responsive
and enter the deceleration stop phase.

The audio system will be muted until the driver becomes responsive.
When the vehicle is decelerating, the brake lights may illuminate, depending on the road
conditions, etc.

Deceleration stop phase

After entering the deceleration stop phase, a buzzer will sound continuously and a
message will be displayed to warn the driver, and the vehicle will slowly decelerate
and stop. After the vehicle stops, the system will enter the stop and hold phase.

Stop hold phase

After the vehicle is stopped, the parking brake will be applied automatically. After
entering the stop and hold phase, the buzzer will continue sounding continuously
and the emergency flashers (hazard lights) will flash to warn other drivers of the
emergency.

Customizable features(P. 783)

Purpose of the Blind Spot Monitor

The Blind Spot Monitor is a system that uses rear side radar sensors installed on
the inner side of the rear bumper on the left and right side to assist the driver in
confirming safety when changing lanes.

WARNING

■

Cautions regarding the use of the system

The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
The Blind Spot Monitor is a supplementary function which alerts the driver that a vehicle
is in a blind spot of the outside rear view mirrors or is approaching rapidly from behind
into a blind spot. Do not overly rely on the Blind Spot Monitor. As the function cannot
judge if it is safe to change lanes, over reliance could lead to an accident resulting in
death or serious injury.
As the system may not function correctly under certain conditions, the driver’s own visual
confirmation of safety is necessary.

INFORMATION

■

Conditions under which the system will not detect a vehicle

The Blind Spot Monitor is not designed to detect the following types of vehicles and/or
objects:

●

Small motorcycles, bicycles, pedestrians, etc.

●

Vehicles traveling in the opposite direction

●

Customizable features(P. 783)

Purpose of the Safe Exit Assist

The Safe Exit Assist (with door opening control) is a system that uses radar sensors
installed on the inner side of the rear bumper to help occupants judge if an
approaching vehicle or bicycle may collide with a door when opening it or cancel
opening of a door, to reduce the possibility of a collision.

WARNING

■

Cautions regarding the use of the system

●

The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings. The safe exit assist is a supplementary system that, when
the vehicle is stopped, informs occupants of the existence of approaching vehicles
and bicycles. As this system alone cannot be used to judge safety, over-reliance on
this system may lead to an accident resulting in death or serious injury. In certain
situations, this system may not function to its fullest extent. Therefore it is necessary for
the occupants to visually check for safety directly and using the mirrors.

INFORMATION

■

Conditions under which the system will not detect a vehicle

●

Safe Exit Assist does not detect the following objects, vehicles, and bicycles:

•

Vehicles or bicycles which are approaching slowly

•

Vehicles or bicycles which are determined to have a low possibility of colliding with
a door (other than the back door) when opened

•

Vehicles or bicycles which are approaching from directly behind

•

Vehicles or bicycles which are approaching from the front

•

Guardrails, walls, signs, parked vehicles, and other stationary objects

•

Pedestrians, animals, etc.

●

In situations such as the following, Safe Exit Assist will not operate:

•

When 3 minutes or more have elapsed since the hybrid system was stopped (the
time which operation is possible may be extended if a door is opened and closed)

•

When your vehicle is not completely stopped

Intuitive parking assist

Purpose of the intuitive parking assist

The distance from your vehicle to nearby obstacles when parallel parking or
maneuvering into a garage is measured by the sensors and communicated via the
displays and a buzzer. Always check the surrounding area when using this system.

WARNING

■

Cautions regarding the use of the system

There is a limit to the degree of recognition accuracy and control performance that this
system can provide, do not overly rely on this system. The driver is always responsible for
paying attention to the vehicle’ surroundings and driving safely.

■

To ensure the system can operate properly

Observe the following precautions. Failing to do so may result in the vehicle being unable
to be driven safely and possibly cause an accident.

●

Do not damage the sensors, and always keep them clean.

●

Do not attach a sticker or install an electronic component, such as a backlit license
plate (especially fluorescent type), fog lights, fender pole or wireless antenna near a
radar sensor.

●

Do not subject the surrounding area of the sensor to a strong impact. If subjected to
an impact, have the vehicle inspected by your Lexus dealer. If the front or rear bumper
needs to be removed/installed or replaced, contact your Lexus dealer.

●

Do not modify, disassemble or paint the sensors.

●

Do not attach a license plate cover.

●

Keep your tires properly inflated.

■

When to disable the function

In the following situations, disable the function as it may operate even though there is no
possibility of a collision.

●

Failing to observe the warnings above.

●

A non-genuine Lexus suspension (lowered suspension, etc.) is installed.

■

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 projecting 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 surrounding 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 ex-
tremely hot or cold.

●

On an extremely bumpy road, on an incline, on gravel, or on grass.

●

When vehicle horns, vehicle detectors, motorcycle engines, air brakes of large vehi-
cles, 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.

●

When a pedestrian is wearing clothing that does not reflect ultrasonic waves (ex. skirts
with gathers or frills).

●

When objects that are not perpendicular to the ground, not perpendicular to the
vehicle traveling direction, uneven, or waving are in the detection range.

●

When strong winds are 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, motorcycle, 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 additional 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
