If a warning message of the Auto matic High Beam is displayed...
It may indicate a malfunction in th e system. Contact your Lexus dealer.■
Temporary lowering sensor sensitivity
The sensitivity of the sensor can be temporarily lowered.
To lower the sensitivity, push and hold on the inside rear view mirror for 15 to
20 seconds, and release. The indicator light on the inside rear view mirror will flash
to indicate that the sensitivity has been lowered.
When the “ENGINE START STOP” switch is turned off, the sensitivity will be
returned to its normal level. ■

Cruise control can be set when ●
The shift lever is in the “D” or range “4” or higher of “S” has been selected. ●
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 s etting 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 accelerating the vehicle to the de sired speed and then pushing the lever
down to set the new speed. ■
Automatic cruise control cancelation
Cruise control will stop maintaining the ve hicle speed in any of the following situa-
tions. ●
Actual vehicle speed falls more than approximately 10 mph (16 km/h) below
the preset vehicle speed.
At this time, the memorized set speed is not retained.●
VSC is activated. ●
Actual vehicle speed is below approximately 25 mph (40 km/h). ●
The switching operation continues for 5 seconds or more after the center dif-
ferential lock switch has been operated.■
If the warning message for the cruise control is shown on the multi-information
display
Press the “ON-OFF” button once to deactiv ate the system, and then press the but-
ton again to reactivate the system.
If the cruise control speed cannot be set or if the cruise control cancels immediately
after being activated, there may be a malfunction in the cruise control system. Have
the vehicle inspected by your Lexus dealer.

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

Automatic cancelation of constant speed control
The cruise control will stop maintaining th e vehicle speed in the following situations:●
Actual vehicle speed is more than approximately 10 mph (16 km/h) below the
set vehicle speed.
At this time, the memorized set speed is not retained.●
Actual vehicle speed falls below approximately 25 mph (40 km/h). ●
VSC is activated. ●
The switching operation continues for 5 seconds or more after the center dif-
ferential lock switch has been operated.■
Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-vehicle
distance control operates properly. (Some obstructions, such as snow, ice and plas-
tic objects, cannot be detect ed by the obstruction sensor.)
Dynamic radar cruise control is canceled if an obstruction is detected.
■
Warning messages and buzzers for dynamic radar cruise control
Warning messages and buzzers are used to indicate a system malfunction or to
inform the driver of the need for caution while driving. (  P. 837)Grille cover

2482-4. Using other driving systems
LX570_OM_OM60L96U_(U) CAUTION■
Situations unsuitable for dy namic radar cruise control
Do not use dynamic radar cruise contro l in any of the following situations.
Doing so may result in inappropriate sp eed control and could cause an accident
resulting in death or serious injury. ●
In heavy traffic ●
On roads with sharp bends ●
On winding roads ●
On slippery roads, such as thos e covered with rain, ice or snow●
On steep downhills, or where there are sudden changes between sharp up and
down gradients
Vehicle speed may exceed the set speed when driving down a steep hill.●
At entrances to expressways ●
When weather conditions are bad enough that they may prevent the sensors
from functioning correctly (fog, sn ow, sandstorm, heavy rain etc.)●
When an approach warning buzzer is heard often ●
When your vehicle is towing a trailer or during emergency towing

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

When driving
LX570_OM_OM60L96U_(U) ■ Buzzer operation and distance to an obstacle
A buzzer sounds when the corner sensors and rear center sensors are
operating.
● The buzzer beeps faster as the vehicle approaches an obstacle.
When the vehicle comes within the following distance of the obsta-
cle, the buzzer sounds continuously:
• Front corner sensors: Approximately 0.8 ft. (25 cm)
• Rear corner sensors: Approximately 1.0 ft. (30 cm)
• Rear center sensors: Approximately 1.6 ft. (50 cm)
● When 2 or more obstacles are d etected simultaneously, the buzzer
system responds to the nearest obst acle. If one or both come within
the above distances, the beep wi ll repeat a long tone, followed by
fast beeps.
● You can change the volume of the warning beeps. (  P. 257)
