In the situations below, the system may not be able to correctly detect the sur-
rounding brightness levels, and may flash or expose nearby pedestrians to the
high beam. Therefore, you should consider turning the high beam on or off
manually rather than relying on the Automatic High Beam system.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The inside rear view mirror or camera sensor is deformed or dirty.
• The camera sensor temperature is extremely high.
• Surrounding brightness levels are equa l to those of headlights, tail lights or
fog lights.
• Vehicles ahead have headlights that are either switched off, dirty, are chang-
ing color, or are not aimed properly.
• When driving through an area of intermittently changing brightness and
darkness.
• When frequently and repeatedly driving ascending/descending roads, or
roads with rough, bumpy or uneven surfaces (such as stone-paved roads,
gravel tracks etc.)
• When frequently and repeatedly taking curves or driving on a winding road.
• There is a highly reflective object ahead of the vehicle, such as a sign or a mir-
ror.
• The back of a vehicle ahead is highly reflective, such as a container on a truck.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or tilting, due to a flat tire, a trailer being towed etc.
• The Automatic High Beam indicator is flashing.
• The high beam and low beam are repeatedly being switched between in an
abnormal manner.
• The driver believes that the high beam may be causing problems or distress to
other drivers or pedestrians nearby.

The windshield wipers and wa sher can be operated when
The “ENGINE START STOP” switch is in IGNITION ON mode. ■
“A U T O ” m o d e
●
If the wiper switch is turned to the “AUTO” position while the “ENGINE START
STOP” switch is in IGNITION ON mode, the wipers will operate once to show
that “AUTO” mode is activated. ●
If the temperature of the rain drop sensor is 176  F (80  C) or higher, or 14  F
(-10  C) or lower, the automatic operation may not occur. In this case, operate
the wipers in any mode other than “AUTO”. Washer/wiper dual operation The wipers operate automati-
cally. (After operating several
times, the wipers operate one
more time after a short delay to
prevent dripping.)
●
The raindrop sensor judges the amount of
raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs etc. are
present on the windshield.

Effects of vehicle speed on wiper operation
With the settings other than “AUTO” also, the time until drip prevention wiper
sweep occurs is changed depending on vehicle speed.
Ty p e A
With selected, wiper operation will be switched from low speed to intermit-
tent wiper operation only when the vehicle is stationary. (However, when the sensor
sensitivity is adjusted to the highest level, the mode cannot be switched.)
Ty p e B
With selected, wiper operation will be switched from low speed to intermit-
tent wiper operation only when the vehicle is stationary. (However, when the sensor
sensitivity is adjusted to the highest level, the mode cannot be switched.) ■
If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the wind-
shield washer fluid reservoir.
CAUTION■
Caution regarding the use of windshield wipers in “AUTO” mode
The windshield wipers may operate unexpect edly if the sensor is touched or the
windshield is subject to vibration in “AUTO” mode. Take care that your fingers etc.
anything else does not become caught in the windshield wipers. ■
Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes warm. The
fluid may freeze on the windshield and cause low visibility. This may lead to an acci-
dent, resulting in death or serious injury.

When driving
LX570_OM_OM60L21U_(U) Driving in vehicle-to-vehicle distance control mode
This mode employs a radar sensor to detect the presence of vehicles up
to approximately 400 ft. (120 m) ah ead, determines the current vehicle-
to-vehicle following distance, and oper ates 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-vehi-
cle distance can also be set by operat ing the vehicle-to-vehicle distance con-
trol.
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 grea ter 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_OM60L21U_(U) ■
Dynamic radar cruise control can be set when ●
The shift lever is in “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 30 mph (50 km/h).■
Accelerating after setting the vehicle speed
The vehicle can accelerate normally. After acceleration, the set speed resumes.
However, during vehicle-to-vehicle distance control mode, the vehicle speed may
decrease below the set speed in order to maintain the distance to the vehicle
ahead. ■
Automatic cancelation of vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the follow-
ing situations: ●
Actual vehicle speed falls below approximately 25 mph (40 km/h). ●
VSC is activated. ●
The sensor cannot operate correctly because it is covered in some way. ●
The windshield wipers are operating at hi gh speed (when the wiper switch is set
to the “AUTO” mode or high speed wiper operation position). ●
When second start mode is set. ●
The switching operation continues for 5 seconds or more after the center dif-
ferential lock switch has been operated.
If vehicle-to-vehicle distance control driving is automatically canceled for any other
reason, there may be a malfunction in the system. Contact your Lexus dealer.
