■High beam automatic turning on or off conditions
●When all of the following conditions are fulfilled, the high beam will be automatically
turned on (after approximately 1 second):
• Vehicle speed is above approximately 40 km/h (25 mph).
• The area ahead of the vehicle is dark.
• There are no vehicles ahead with headlights or tail lights turned on.
• There are few streetlights on the road ahead.
●If any of the following conditions are fulfilled, the high beam will be automatically turned
off:
• Vehicle speed drops below approximately 30 km/h (19 mph).
• The area ahead of the vehicle is not dark.
• Vehicles ahead have headlight s or tail lights turned on.
• There are many streetlights on the road ahead.
■Camera sensor detection information
●The high beam may not be automatically turned off in the following situations:
• When oncoming vehicles suddenly appear from a curve
• When the vehicle is cut in front of by another vehicle
• When vehicles ahead are hidden from sight due to repeated curves, road dividers or roadside trees
• When vehicles ahead appear from the faraway lane on wide road
• When vehicles ahead have no lights
●The high beam may be turned off if a vehicl e ahead that is using fog lights without using
the headlights is detected.
●House lights, street lights, traffic signals, and illuminated billboards or signs may cause
the high beam to switch to the low beams, or the low beams to remain on.
●The following factors may affect the amount of time taken to turn the high beam on or
off:
• The brightness of headlights, fog li ghts, and tail lights of vehicles ahead
• The movement and direction of vehicles ahead
• When vehicle ahead only has operational lights on one side
• When vehicle ahead 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
●The high beam may be turned on or off when the driver does not expect it.
●Bicycles or similar objects may not be detected.
●In the situations shown below, the system may not be able to accurately detect sur-
rounding brightness levels. This may cause the low beams to remain on or the high
beams to cause problems for pedestrians, vehicles ahead or other parties. In these
cases, manually switch between the high and low beams.
• 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 th ose 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.

The wipers can be used as intermittent windshield wipers, which operate regard-
less of vehicle speed or amount of raindrops. The intermittent windshield wiper
operation can be switched when the vehicle is stopped and the wiper is off. The
wiper operation cannot be switched duri ng AUTO mode or while the intermit-
tent windshield wipers are operating.
Press and hold until the AUTO
mode indicator stops flashing.
If is pressed and held until the
AUTO mode indicator stops flashing
again, it will return to its previous state.
■The windshield wiper and washer can be operated when
The engine switch is in IGNITION ON mode.
■Dripping prevention wiper sweep
After washing and wiping operation several times, the wipers operate one more time
after a short delay to prevent dripping.
However, the last sweep will not happen while the vehicle is moving.
■Effects of vehicle speed on wiper operation
●Intermittent windshield wipers interval changes when the vehicle is stopped.
●With low speed operation selected, wiper operation will be switched from low speed to
intermittent operation only wh en the vehicle is stationary.

■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If AUTO mode is selected while the engine switch is in IGNITION ON mode, the wip-
ers will operate once to show that AUTO mode is activated.
●If the temperature of the raindrop sensor is 85°C (185°F) or higher, or -30°C
(-22°F) or lower, automatic operation may not occur. In this case, operate the wip-
ers in any mode other than AUTO mode.
■When the windshield wipers are in temporary operation
AUTO mode cannot be activated even if is pressed.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the windshield
washer fluid reservoir.
●The raindrop sensor judges the amount of
raindrops.
An optical sensor is adopted. It may not oper-
ate 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 regarding the use of windshield wipers in AUTO mode
The windshield wipers may operate unexpectedly if the sensor is touched or the wind-
shield is subject to vibration in AUTO mode. Take care that your fingers or anything
else do not become caught in the windshield wipers.
■Caution regarding the use of washer fluid
When it is cold, do not use the washer fl uid 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.

2804-4. Refueling
GS350_200t_GS F_OM_OM30E87E_(EE)
Opening the fuel tank cap
●Turn the engine switch off and ensure that all the doors and windows are
closed.
●Confirm the type of fuel.
■Fuel types
→P. 6 2 6
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehicle has a fuel tank opening that only accom-
modates the special nozzle on unleaded fuel pumps.
Perform the following steps to open the fuel tank cap:
Before refueling the vehicle
WA R N I N G
■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 fr om 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, pressurized fuel
may spray out the filler neck and cause injury.
●Do not allow anyone that has not discharged 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.
