●

Range 4 or higher has been selected by using the paddle shift. (vehicles with paddle

shift switches)

●

Vehicle speed is above approximately 25 mph (40 km/h).

■

Accelerating after setting the vehicle speed

●

The vehicle can be accelerated normally. After acceleration, the set speed resumes.

●

Even without canceling the cruise control, the set speed can be increased by first accel-

erating the vehicle to the desired speed and then pushing the lever down to set the new

speed.

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 following distance of the obstacle, the
buzzer sounds continuously.

• Front center sensors: Approximately 1.1 ft. (35 cm)
• Corner: Approximately 1.1 ft. (35 cm)
• Rear center sensors: Approximately 1.6 ft. (50 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 dis-
tances, the beep will repeat a long tone, followed by fast beeps.

●

You can change the volume of the warning beeps. (

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

• The vehicle speed is less than approximately 6 mph (10 km/h).

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

●

Front center sensors:

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

• The vehicle speed is less than about 6 mph (10 km/h).

●

Rear corner and rear center sensors:
• The engine switch is in IGNITION ON mode.

• The shift lever is in R.

■

Intuitive parking assist display

When an obstacle is detected while the rear view monitor system, Lexus parking assist

monitor or Multi-terrain Monitor is in use, the warning indicator will appear in the upper

corner of the screen even if the display setting has been set to off.

■

Sensor detection information

●

The sensor’s detection areas are limited to the areas around the vehicle’s bumper.

●

Certain vehicle conditions and the surrounding 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 prob-

lem.)

• 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.

• The bumper or sensor receives a strong impact.

• 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 (lowered 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.

300

4-5. Using the driving support systems

●

The shape of the obstacle may prevent a sensor from detecting it. Pay particular atten-

tion 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 projecting outwards in the direction of your vehi-

cle

●

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 impossible.

• 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 sensor 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.

■

If “Clean Parking Assist Sensor” is displayed on the multi-information display

A sensor may be dirty or covered with snow or ice. In such cases, if it is removed from the

sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a malfunction display may

appear or an obstacle may not be detected. If the sensor thaws out, the system should

return to normal.

■

If “Parking Assist Malfunction” is displayed on the multi-information display

Depending on the malfunction of the sensor, the device may not be working normally.

Have the vehicle inspected by your Lexus dealer.

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 possibly

cause an accident.

●

Do not use the sensor at speeds in excess of 6 mph (10 km/h).

●

The sensors’ detection areas and reaction times are limited. When moving forward or

reversing, check the areas surrounding the vehicle (especially the sides of the vehi-

cle) 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 sensor mal-

function etc. Have the vehicle checked by your Lexus dealer.

●

A buzzer does not sound when you turn the intuitive parking assist on.

●

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 without a buzzer.

●

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.

■

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 malfunctioning.

■

“HI” (high) height mode

Vehicle height is about 2.0 in. (50 mm) higher at the front, and about 2.4 in.
(60 mm) higher at the rear than the normal mode height.
This mode is suitable when driving on bumpy roads or through water.
High height mode is only available when the vehicle speed is under 18 mph
(30 km/h).

■

N (normal) height mode

The standard vehicle height. This mode is suitable for ordinary driving.
When driving at high speeds, the vehicle height is automatically lowered by
0.8 in. (20 mm) in the front and 0.6 in. (15 mm) in the rear, to ensure excellent
aerodynamic characteristics and stability.
If the vehicle speed drops, normal height mode is automatically resumed.

■

“LO” (low) height mode

Vehicle height is about 2.4 in. (60 mm) lower at the front, and about 1.6 in. (40
mm) lower at the rear than the normal mode height.
This mode allows easy access to the vehicle.
Low height mode is only available when the vehicle is travelling at 7 mph
(12 km/h) or less. When the vehicle speed exceeds 7 mph (12 km/h), normal
height mode is automatically selected.
