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.

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-

Buzzer operation and distance to
an obstacle
A buzzer sounds when the sensors are
operating.
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.

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
