■The Adaptive High-beam System can be operated when
The engine switch is in IGNITION ON mode.
■Camera sensor detection information
●High beam may not be automatically turned off or changed to variable shade beam
in the following situations:
• When oncoming vehicles suddenly appear from a curve
• When the vehicle is cut in front of by another
• When oncoming or preceding vehicles are hidden from sight due to repeated
curves, road dividers or roadside trees
●High beam may be turned off or variable shade beam may be changed to if an
oncoming vehicle that is using fog lights without 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 or variable shade beam to be changed to and may
change the area that is shielded.
●The following factors may affect the amount of time taken to turn high beam on or
off, or the speed by which the shielded areas change:
• The brightness of headlights, 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 only has operational lights on one side
• When a oncoming or preceding vehicle is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of the road surface etc.)
• The number of passengers and amount of luggage
●High beam and variable shade beam may be turned on or off when unexpected by
the driver.
●Small vehicles, such as bicycles, may not be detected.

3024-3. Operating the lights and wipers
LS460/LS460L_GE (OM50G06E)
■The windshield wiper and washer can be operated when
The engine switch is in IGNITION 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 170 km/h
(106 mph).
■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 wiper 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 engine switch is in IGNITION ON
mode, the wipers will operate once to show that “AUTO” mode is activated.
●If the temperature of the raindrop sensor is 90 C (194F) or higher, or -15C
(5 F) or lower, automatic operation may not occur. In this case, operate the wip-
ers 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. 445
●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.

3064-4. Refueling
LS460/LS460L_GE (OM50G06E)
CAUTION
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do so may
result in death or serious injury.
●After exiting the vehicle and before opening the fuel door, touch an unpainted
metal surface to discharge any static electricity. It is important to discharge static
electricity before refueling because sparks resulting from static electricity can
cause fuel vapors to ignite while refueling.
●Always hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened. Wait until
the sound cannot be heard before fully removing the cap. In hot weather, pressur-
ized fuel may spray out the filler neck and cause injury.
●Do not allow anyone that has not discharg ed static electricity from their body to
come close to an open fuel tank.
●Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
●Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
●Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition hazard.
■When refueling
Observe the following precautions to prevent fuel overflowing from the fuel tank:
●Securely insert the fuel nozzle into the fuel filler neck.
●Stop filling the tank after the fuel nozzle automatically clicks off.
●Do not top off the fuel tank.
NOTICE
■Refueling
Do not spill fuel during refueling.
Doing so may damage the vehicle, such as causing the emission control system to
operate abnormally or damaging fuel system components or the vehicle’s painted
surface.
