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)

The shape of the obstacle may prevent the sensor from detecting it. Pay partic-
ular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materi als that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projec ting 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 dis-
tance 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 sen-
sor’s detection areas before the di splay is shown and the warning beep
sounds.
• Thin posts or objects lower than the se nsor may not be dete cted for collision
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 air conditioning system.■

Cold weather operation
It may take longer for the vehicle height to change if the suspension fluid tempera-
ture drops below 5°F (-15°C).
The 4-Wheel AHC does not operate when the suspension fluid temperature drops
below -22°F (-30°C). ●
In this case, even if the height select switch is pressed, the vehicle height will not
change. Once the vehicle has been driven for a short time and the suspension
fluid has been warmed to within normal operating limits, the 4-Wheel AHC will
begin operating and the vehicle height wi ll automatically change to the selected
mode. ●
When the suspension fluid is around -22°F (-30°C), the vehicle height may not
be able to be raised, even if the 4-Wheel AHC is operating. In this case, pull the
height select switch to “  ” then push to “  ” after driving for a short time longer
to select the desired vehicle height.■
Parking and stopping tips ●
If you immediately stop the engine after off-road driving, the vehicle height may
gradually lower. When parking, make su re there is nothing under the vehicle
that may come in contact with the underbody. The vehicle will return to the set
height when the engine is started. ●
The vehicle height may change as the temperature changes when the engine is
stopped. The vehicle will return to the set height when the engine is started.■
Propeller shaft noise
If the vehicle height is adjusted on a slope, or with the shift lever in a position other
than “P” or “N” while the vehicle is stop ped, you may hear a sound caused by the
expansion and contraction of the propeller shaft. This does not indicate a malfunc-
tion. ■
4-Wheel AHC failure warning
If a malfunction occurs in the 4-Wheel AHC, normal mode is automatically
selected. However, the system may not sw itch to normal mode depending on the
location of the malfunction.
The warning message is displayed on the multi-information display, and the 4-
Wheel AHC cannot be activated until the malfunction is corrected.
Stop the engine and start it again. If th e warning message turns off, the system is
operating correctly. If the warning message continues to be displayed, have the
vehicle checked at your Lexus dealer as soon as possible.

Sounds and vibrations caused by the Crawl Control system ●
A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indicate that
a malfunction has occurred in Crawl Control system. ●
Either of the following conditions may occur when the Crawl Control system is
operating. None of these are indicat ors that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.■
When there is a malfunction in the system
Warning lights and/or warning messages will turn on. (  P. 827, 852)
CAUTION■
When using Crawl Control and Turn Assist function
Do not rely solely on the Crawl Control an d Turn Assist function. This function does
not extend the vehicle’s performance limi tations. Always thoroughly check the
road conditions, and drive safely. ■
These conditions may cause the system not to operate properly
When driving on the following surfaces, th e system may not be able to maintain a
fixed low speed, which may result in an accident:●
Extremely steep inclines. ●
Extremely uneven surfaces. ●
Snow-covered roads, or other slippery surfaces.
NOTICE■
When using Turn Assist function
The Turn Assist function is a function to assist turning performance when driving off
road. The function may be less effective on paved road surfaces.

When driving
LX570_OM_OM60L96U_(U) Pre-Collision System 
 : If equippedWhen the radar sensor detects possibilit y of a frontal collision, the pre-col-
lision systems such as the brakes and seat belts are automatically engaged
to lessen impact as well as vehicle damage.
■ Pre-collision seat belts (front seats only) If the pre-collision sensor detects that a collision is unavoidable, the pre-
collision system will retract the seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or loses
control of the vehicle. (  P. 94)
However, when the VSC system is disabled, the system will not operate in
the event of skidding.
■ Pre-collision brake assist When there is a high possibility of a frontal collision, the system applies
greater braking force in relation to how strongly the brake pedal is
depressed. The system may not warn the driver using a warning light,
warning display and buzzer when the system detects and judges braking
operations.
■ AVS control When the system determines that there is a high possibility of a frontal col-
lision, the AVS optimizes the damping effect. (  P. 331)

LX570_OM_OM60L96U_(U) ■
Situations in which the pre-collision system does not function properly
The system may not function effectively in situations such as the following: ●
On roads with sharp bends or uneven surfaces ●
If a vehicle suddenly moves in front of your vehicle, such as at an intersection ●
If a vehicle suddenly cuts in front of your vehicle, such as when overtaking●
In inclement weather such as heavy rain, fog, snow or sand storms ●
When your vehicle is skidding such as the VSC system off●
When your vehicle is steeply inclined ●
When the axis of the radar is out of adjustment■
Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in the
sensors being unable to detect obstacles, the pre-collision system will be automati-
cally disabled. In this case, th e system will not activate even if there is a collision pos-
sibility. ■
When there is a malfunction in the system, or if the system is temporarily unus-
able
Warning lights and/or warning messa ges will turn on or flash. (  P. 826, 837)
