using the headlights is detected.
●House lights, street lights, red traffic signals, and illuminated billboards or signs may
cause the high beam to turn off.
●The following factors may affect the amount of time taken to turn high beam on or
off:
• The brightness of headligh ts, fog lights, and tail lights of oncoming and preced-
ing vehicles
• The movement and direction of oncoming and preceding vehicles
• When a oncoming or preceding vehicle on ly has operational lights on one side
• When a oncoming or preceding vehicle is a two-wheeled vehicle

●In the situations below, the system may not be able to correctly detect the sur-
rounding brightness levels, and may flash or expose oncoming or preceding vehi-
cles to the high beam or may continue using the low beam. Therefore, in these
situations you should consider turning th e high beams 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 equal to those of headlights, tail lights or fog lights.
• Vehicles ahead have headlights that are either switched off, dirty, are changing color, or have are not aimed properly.
• When driving through an area of interm ittently changing brightness and dark-
ness.
• 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 mirror.
• 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.

Decreases the sensitivity
Washer/wiper dual operation
Wipers will automatically operate a
couple of times after the washer
squirts.
■The windshield wiper and washer can be operated when
The power switch is in ON mode.
■Dripping prevention wiper sweep
After washing and the wiper has operated several times, the wipers operate one
more time after a short delay to prevent dripping.
However, the last sweep will not happen if the vehicle is traveling above 106 mph
(170 km/h).
■Effects of vehicle speed on wiper operation
Even when the wipers are not in “AUTO” mode, vehicle speed affects the time until
the drip prevention wiper sweep occurs.
With low speed windshield wiper operation selected, wiper operation will be
switched from low speed to intermittent wi per operation only when the vehicle is sta-
tionary.
(However, when the sensor sensitivity is adjusted to the highest level, the mode can-
not be switched.)

■Raindrop sensor
●If the wiper is turned to “AUTO” mode while the power switch is in ON mode, the
wipers will operate once to show that “AUTO” mode is activated.
●If the temperature of the raindrop sensor is 194°F (90°C) or higher, or 5°F (-15°C)
or lower, automatic operation may not occur. In this case, operate the wipers in any
mode other than “AUTO” mode.
■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.
■Outside rear view mirror defogger activation linked to windshield wiper operation
The outside rear view mirror defoggers automatically turn on when you operate the
windshield wipers.
The outside rear view mirror defoggers automatically turn off approximately 15 min-
utes after the wipers stop.
For details about the outside rear view mirror defoggers: P. 3 5 8
●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.
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 or
anything else do not become ca ught 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
accident, resulting in death or serious injury.

Driving
LS600hL_U(OM50E41U)
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 opera tes to maintain a suitable following
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 operating the vehicle-to-vehicle distance control.
Example of deceleration cruising and follow-up cruising
When the vehicle ahead is driving slower than the set speed
When a vehicle is detected running ahead of you, the system automatically decel-
erates your vehicle. When a greater reduction in vehicle speed is necessary, the
system applies the brakes. The system will respond to changes in the speed of the
vehicle ahead in order to maintain the vehicle-to-vehicle distance set by the
driver. A warning tone warns you when the system cannot decelerate sufficiently
to prevent your vehicle from closing in on the vehicle ahead. When the vehicle
ahead of you stops, your vehicle will also stop. After the vehicle ahead starts off,
pushing the cruise control lever up or depressing the accelerator pedal will
resume follow-up cruising.
