WARNING

■

When using the intuitive parking

assist

Observe the following precautions.

Failing to do so may result in the vehicle

being unable to be driven safely and pos-

sibly cause an accident.

●

Do not use the sensor at speeds in

excess of 6 mph (10 km/h).

●

The sensors’ detection areas and reac-

tion times are limited. When moving

forward or reversing, check the areas

surrounding the vehicle (especially the

sides of the vehicle) for safety, and

drive slowly, using the brake to control

the vehicle’s speed.

●

Do not install accessories within the

sensors’ detection areas.

●

The area directly under the bumpers is

not detected.

Thin posts or objects lower than a sen-

sor may not be detected when

approached, even if they have been

detected once.

■

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.

●

The vehicle is equipped with a fender

pole, wireless antenna or fog lights.

●

The front or rear bumper or a sensor

receives a strong impact.

●

A non-genuine Lexus suspension

(lowered suspension, etc.) is installed.

●

Towing eyelets are installed.

●

A backlit license plate is installed.

■

When using intuitive parking assist

In the following situations, the system

may not function correctly due to a sen-

sor malfunction, etc. Have the vehicle

checked by your Lexus dealer.

●

The intuitive parking assist operation

display flashes or shows continuously,

and a buzzer sounds when no objects

are detected.

●

If the area around a sensor collides

with something, or is subjected to

strong impact.

●

If the bumper or grille collides with

something.

●

If the display flashes or is displayed

continuously and a buzzer does not

sound, except when the mute function

has been turned on.

●

If a display error occurs, first check the

sensor.

If the error occurs even when there is

no ice, snow or mud on the sensor, it is

likely that the sensor is malfunctioning.

■

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 mal-

functioning.

●

When using a high pressure washer to

wash the vehicle, do not spray the sen-

sors directly, as doing so may cause a

sensor to malfunction.

●

When using steam to clean the vehicle,

do not direct steam too close to the

sensors as doing so may cause a sen-

sor to malfunction.

Driving

■

The intuitive parking assist can be oper-

ated when

●

Front center sensors:

• The engine switch is in IGNITION ON

mode.

• The shift lever is in a position other than P

or R.

• The vehicle speed is less than about 6

mph (10 km/h).

●

Front corner sensors:

• The engine switch is in IGNITION ON

mode.

• The shift lever is in a position other than P.

• The vehicle speed is less than about 6

mph (10 km/h).

(At any speed when the shift lever is in R)

●

Rear corner and rear center sensors:

• The engine switch is in IGNITION ON

mode.

• The shift lever is in R.

■

Muting the buzzer sound

●

To mute the buzzer sound:

The buzzer can be temporarily muted by

pressing “OK” of the meter control

switches while an obstacle detection dis-

play is shown on the multi-information dis-

play.

●

To cancel the mute:

Mute will be automatically canceled in the

following situations.

• When the shift position is changed

(except shifting from D to N, or N to D).

• When the vehicle speed has reached or

exceeded 6 mph (10 km/h) with the shift

position in D.

• When the intuitive parking assist is turned

off once and turned on again.

• When the engine switch is turned off

once and turned to IGNITION ON

mode again.

■

If “Clean Parking Assist Sensor” is dis-

played on the multi-information display

A sensor may be covered with ice, snow,

dirt, etc. Remove the ice, snow, dirt, etc.,

from the sensor to return the system to nor-

mal.
Also, due to ice forming on a sensor at low

temperatures, a warning message may be

displayed or the sensor may not be able to

detect an object. Once the ice melts, the

system will return to normal.

■

Sensor detection information

●

The following situations may occur

during use.

• The sensors may be able to only detect

objects near the front and rear bumpers.

• Depending on the shape of the object

and other factors, the detection distance

may shorten, or detection may be impos-

sible.

• There will be a short delay between

object detection and display. Even at low

speeds, there is a possibility that the

object will come within the sensor’s

detection areas before the display is

shown and the warning beep 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 buzzer if

buzzers for other systems are sounding.

■

Conditions under which the function

may not function correctly

Certain vehicle conditions and the sur-

rounding environment may affect the ability

of a sensor to correctly detect objects. Par-

ticular instances where this may occur are

listed below.

●

There is dirt, snow 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 dis-

played abnormally, or objects, such as a

wall, may not be detected.

●

A sensor is covered in any way.

●

When a sensor or the area around a sen-

sor is extremely hot or cold.

●

On an extremely bumpy road, on an

incline, on gravel, or on grass.

●

The vicinity of the vehicle is noisy due to

vehicle horns, motorcycle engines, air

brakes of large vehicles, or other loud

noises producing ultrasonic waves.

●

There is another vehicle equipped with

186

4-5. Using the driving support systems

parking assist sensors in the vicinity.

●

A sensor is coated with a sheet of spray

or heavy rain.

●

If a sensor is hit by a large amount of

water, such as when driving on a flooded

road.

●

If the vehicle is significantly tilted.

●

The vehicle is approaching a tall or

curved curb.

●

If objects draw too close to the sensor.

■

Objects which 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 project-

ing outwards in the direction of your vehi-

cle

The buzzer beeps faster as the vehi-
cle approaches an obstacle. When
the vehicle comes within the follow-
ing distance of the obstacle, the
buzzer sounds continuously:

• Front center sensors: Approximately 1.0

ft. (30 cm)

• Corner sensors: Approximately 1.0 ft.

(30 cm)

• Rear center sensors: Approximately 1.1 ft.

(35 cm)



When 2 or more obstacles are

detected simultaneously, the buzzer
system responds to the nearest
obstacle. If one or both come within
the above distances, the beep will
repeat a long tone, followed by fast
beeps.

WARNING

■

Cautions regarding the use of the

function

The driver is solely responsible for safe

driving. Always drive safely, taking care

to observe your surroundings.
The BSM function 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 rap-

idly from behind into a blind spot. Do not

overly rely on the BSM function. 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.
The RCTA function is only a supplemen-

tary function which alerts the driver that a

vehicle is approaching from the right or

left at the rear of the vehicle. As the

RCTA function may not function cor-

rectly under certain conditions, the

driver’s own visual confirmation of safety

is necessary. Over reliance on this func-

tion may lead to an accident resulting

death or serious injury.

■

TRAC (Traction Control)

Helps to maintain drive power and pre-
vent the drive wheels from spinning
when starting the vehicle or accelerat-
ing on slippery roads

■

Hill-start assist control

Helps to reduce the backward move-
ment of the vehicle when starting on an
uphill

■

VGRS (Variable Gear Ratio Steer-
ing) (if equipped)

Adjusts the front wheel turning angle in
accordance with the vehicle speed and
steering wheel movement

■

DRS (Dynamic Rear Steering) (if
equipped)

Contributes to the turning characteris-
tics and responsiveness of the vehicle
by adjusting the rear wheel angle of the
vehicle in accordance with steering
wheel movement.

■

EPS (Electric Power Steering)

Employs an electric motor to reduce
the amount of effort needed to turn the
steering wheel

■

Adaptive Variable Suspension Sys-
tem (if equipped)

By independently controlling the
damping force of the shock absorbers
for each of the 4 wheels according to
the road and driving conditions, this
system combines riding comfort with
superior vehicle stability, and helps
good vehicle posture.

■

LDH (Lexus Dynamic Handling
system) (if equipped)

Provides integrated control of the
VGRS, DRS and EPS. Contributes to
turning characteristics at low speeds,
responsiveness at medium speeds and
safety at high speeds by controlling the
steering angle of the front and rear
wheels in accordance with the steering
wheel operation and vehicle speed.

■

VDIM (Vehicle Dynamics Inte-
grated Management)

Provides integrated control of the
ABS, brake assist, TRAC, VSC,
hill-start assist control, EPS and VGRS
systems
Helps to maintain vehicle stability when
swerving on slippery road surfaces by
controlling the brakes, engine output,
steering assist, and steering ratio
