After the vehicle ahead of you starts
off, push the lever up.
Your vehicle will also resume follow-up
cruising if the accelerator pedal is
depressed after the vehicle ahead of
you starts off.

Pulling the lever toward you can-
cels the speed control.

The speed control is also canceled when
the brake pedal is depressed.
(When the vehicle has been stopped by
system control, depressing the brake pedal
does not cancel the setting.)

Pushing the lever up resumes the
cruise control and returns vehicle
speed to the set speed.

However, when a vehicle ahead is not
detected, cruise control does not resume
when the vehicle speed is approximately
25 mph (40 km/h) or less.

When your vehicle is too close to a
vehicle ahead, and sufficient automatic
deceleration via the cruise control is
not possible, the display will flash and
the buzzer will sound to alert the driver.
An example of this would be if another
driver cuts in front of you while you are
following a vehicle. Depress the brake
pedal to ensure an appropriate vehi-
cle-to-vehicle distance.

Sensor detection information

●

The sensor’s detection areas are limited

to the areas around the vehicle’s bumper.

●

Certain vehicle conditions and the sur-

rounding environment may affect the

ability of a sensor to correctly detect an

obstacle. Particular instances where this

may occur are listed below.

• There is dirt, snow or ice on the sensor.

(Wiping the sensors will resolve this

problem.)

• The sensor is frozen. (Thawing the area

will resolve this problem.)

In especially cold weather, if a sensor is

frozen the screen may show an abnormal

display, or obstacles may not be

detected.

• The sensor is covered in any way.

• The vehicle is leaning considerably to one

side.

• 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

parking assist sensors in the vicinity.

• The sensor is coated with a sheet of spray

or heavy rain.

• The vehicle is equipped with a fender

pole or wireless antenna.

• Towing eyelets are installed.

• The bumper or sensor receives a strong

impact.

• A backlit license plate, license plate

holder, etc., are installed.

• The vehicle is approaching a tall or

curved curb.

• In harsh sunlight or intense cold weather.

• The area directly under the bumpers is

not detected.

• If obstacles draw too close to the sensor.

• A non-genuine Lexus suspension (low-

ered suspension etc.) is installed.

• People may not be detected if they are

wearing certain types of clothing.

In addition to the examples above, there are
instances in which, because of their shape,
signs and other objects may be judged by a
sensor to be closer than they are.

●

The shape of the obstacle may prevent a

sensor from detecting it. Pay particular

attention to the following obstacles:

• Wires, fences, ropes, etc.

• Cotton, snow and other materials that

absorb sound waves

• Sharply-angled objects

• Low obstacles

• Tall obstacles with upper sections pro-

jecting outwards in the direction of your

vehicle

●

The following situations may occur

during use.

• Depending on the shape of the obstacle

and other factors, the detection distance

may shorten, or detection may be impos-

sible.

• Obstacles may not be detected if they

are too close to the sensor.

• There will be a short delay between

obstacle detection and display. Even at

slow speeds, there is a possibility that the

obstacle will come within the sensor’s

detection areas before the display is

shown and the buzzer sounds.

• Thin posts or objects lower than the sen-

sor may not be detected when

approached, even if they have been

detected once.

• It might be difficult to hear beeps due to

the volume of audio system or air flow

noise of the air conditioning system.

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.

NOTICE

■

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, and a buzzer sounds

when no obstacles are detected.

●

If the area around a sensor collides

with something, or is subjected to

strong impact.

●

If the bumper collides with something.

●

If the display shows continuously with-

out beeping, except when the buzzer

mute switch has been turned on.

●

If a display error occurs, first check the

sensor.

If the error occurs even if there is no

ice, snow or mud on the sensor, it is

likely that the sensor is malfunctioning.

Buzzer operation and distance to
an obstacle

A buzzer sounds when the sensors are
operating.

 The buzzer sounds faster as the

vehicle approaches an obstacle.
When the vehicle comes within the
approximately 1.0 ft. (30 cm) of the
obstacle, the buzzer sounds contin-
uously.

 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.

 Automatic buzzer mute function:

After a buzzer begins sounding, if
the distance between the vehicle
and the detected object does not
become shorter, the buzzer will be
muted automatically. (However, if
the distance between the vehicle
and object is 1.0 ft. (30 cm) or less,
this function will not operate.)

obstacle while parking or traveling
at low speeds, when the vehicle
suddenly moves forward due to
mistaken accelerator pedal opera-
tion, or when the vehicle moves due
to the shift lever being in the wrong
position, the sensors detect obsta-
cles to the front or rear in the travel-
ing direction of the vehicle, and the
system operates to lessen impact
with obstacles such as walls, and
reduce resulting damage.
