Pulling the lever toward you
cancels the cruise control. The speed setting is also can-
celed when the brakes are
applied.
Pushing the lever up resumes
the cruise control and returns
vehicle speed to the set
speed. Resuming is available when the
vehicle speed is more than
approximately 25 mph (40 km/
h)

When driving
LX570_OM_OM60L96U_(U) Driving in vehicle-to-veh icle distance control mode
This mode employs a radar sensor to detect the presence of vehicles up
to approximately 400 ft. (120 m) ahead, determines the current vehicle-
to-vehicle following distance, and operates to maintain a suitable follow-
ing distance from the vehicle ahead. Note that vehicle-to-vehicle distance will close in when traveling on long
downhill slopes.
Example of constant speed cruising
When there are no vehicles ahead The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle distance can also be set by op erating the vehicle-to-vehicle distance
control.
Example of deceleration cruising
When the vehicle ahead is driving slower than the set speed When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is nec-
essary, the system applies the brakes . A warning tone warns you when the
system cannot decelerate sufficiently to prevent your vehicle from closing in
on the vehicle ahead.

2422-4. Using other driving systems
LX570_OM_OM60L96U_(U) Example of follow-up cruising
When following a vehicle driving slower than the set speed The system continues follow-up cruising while adjusting for changes in the
speed of the vehicle ahead in order to maintain the vehicle-to-vehicle dis-
tance set by the driver.
Example of acceleration
When there are no long er any vehicles ahead driving slower than the
set speed The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.
Approach warning
When your vehicle is too close to a vehicle ahead, and sufficient auto-
matic deceleration via the cruise co ntrol is not possible, the display will
flash and the buzzer will sound to al ert the driver. An example of this
would be if another driver cuts in fron t of you while you are following a
vehicle. Apply the brakes to ensure appropriate vehicle-to-vehicle dis-
tance.
■ Warnings may not occur when
In the following instances, there is a possibility th at the warnings will not
occur:
● When the speed of the vehicle ahead matches or exceeds your
vehicle speed
● When the vehicle ahead is traveling at an extremely slow speed
● Immediately after the cruise control speed was set
● At the instant the accelerator is applied

When driving
LX570_OM_OM60L96U_(U) CAUTION■
Before using dynamic radar cruise control
Do not overly rely on vehicl e-to-vehicle distance control.
Be aware of the set speed. If automatic deceleration/acceleration is not appropri-
ate, adjust the vehicle speed, as well as the distance between your vehicle and vehi-
cles ahead by applying the brakes, etc. ■
Cautions regarding the driving assist systems
Observe the following precautions.
Failure to do so may cause an accident resulting in death or serious injury.●
Assisting the driver to measure following distance
The dynamic radar cruise control is only in tended to help the driver in determin-
ing the following distance between the driver’s own vehicle and a designated
vehicle traveling ahead. It is not a mech anism that allows careless or inattentive
driving, and it is not a system that can assist the driver in low-visibility conditions. It
is still necessary for driver to pay close attention to the vehicle’s surroundings. ●
Assisting the driver to judg e proper following distance
The dynamic radar cruise control dete rmines whether the following distance
between the driver’s own vehicle and a designated vehicle traveling ahead is
appropriate or not. It is not capable of making any other type of judgement.
Therefore, it is absolutely necessary for the driver to remain vigilant and to deter-
mine whether or not there is a possibi lity of danger in any given situation.●
Assisting the driver to operate the vehicle
The dynamic radar cruise control has no capability to prevent or avoid a collision
with a vehicle traveling ahead. Therefore, if there is ever any danger, the driver
must take immediate and direct control of the vehicle and act appropriately in
order to ensure the safety of all involved.■
To avoid inadvertent cruise control activation
Switch the cruise contro l off using the “ON-OFF” button when not in use.

When driving
LX570_OM_OM60L96U_(U) CAUTION■
When the radar sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles are in
front of you.
As the sensor may not be able to correctly detect these types of vehicles, the
approach warning (  P. 242) will not be activated, and a fatal or serious accident
may result: ●
Vehicles that cut in suddenly ●
Vehicles traveling at low speeds ●
Vehicles that are not moving ●
Vehicles with small rear ends (trailers with no load on board etc.) ●
Motorcycles traveling in the same lane■
Conditions under which the vehicle-to-veh icle distance control may not function
correctly
Apply the brakes as necessary in the following conditions as the radar sensor may
not be able to correctly detect vehicles ahead, and a fatal or serious accident may
result: ●
When water or snow thrown up by the surrounding vehicles hinders the function-
ing of the sensor ●
When your vehicle is pointing upwards (caused by a heavy load in the luggage
compartment, etc.) ●
When the road curves or when the lanes are narrow ●
When steering wheel operation or your position in the lane is unstable●
When the vehicle ahead of you decelerates suddenly

Sensor detection information ●
The sensor’s detection areas are limited to the areas around the vehicle’s front
corner and rear bumpers. ●
Certain vehicle conditions and the surrounding environment may affect the
ability of the sensor to correctly detect obstacles. Particular instances where
this may occur are listed below.
• There is dirt, snow or ice on the sens or. (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 sensor s 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 hook is installed.
• 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 (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 ju dged by the sensor to be closer than
they are.

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 possi-
bly 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 for-
ward or reversing, check the areas surro unding 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 ma y not function correctly due to a sensor
malfunction etc. Have the vehicle checked by your Lexus dealer. ●
A beep does not sound when you turn the main switch on. ●
The intuitive parking assist operation disp lay flashes, and a beep 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 beep. ●
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 wa ter or steam to the sensor area.
Doing so may result in the sensor malfunctioning.

LX570_OM_OM60L96U_(U) CAUTION■
When using the rear view monitor system
The rear view monitor system is a suppleme ntal device intended to assist the driver
when backing up. When backing up, be sure to check visually behind and all
around the vehicle before proceeding.
Observe the following precautions to avoid an accident that could result in death or
serious injuries. ●
Never depend on the rear view monitor system entirely when backing up. The
image and the position of the guide lines displayed on the screen may differ from
the actual state.
Use caution, just as you would when backing up any vehicle. ●
When parking, be sure to check that the parking space will accommodate your
vehicle before maneuvering into it. ●
Be sure to back up slowly, depressing the brake pedal to control vehicle speed.●
In low temperatures, the screen may darken or the image may become faint. The
image could distort when the vehicle is moving, or you may become unable to
see the image on the screen. Be sure to check direct visually and with the mirrors
all around the vehicl e before proceeding.●
The camera uses a special lens. The di stances between objects and pedestrians
that appear in the image displayed on the screen will differ from the actual dis-
tances. (  P. 292)
