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.

windshield wipers (vehicles with rain-sensing windshield wipers)

■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.

■Pre-crash braking*3
●The pre-crash braking function may not operate if certain operations are performed
by the driver. If the accelerator pedal is being depressed strongly or the steering
wheel is being turned, the system may determine that the driver is taking evasive
action and possibly prevent the pre-crash braking function from operating.
●In some situations, while the pre-crash braking function is operating, operation of the
function may be canceled if the accelerator pedal is depressed strongly or the steer-
ing wheel is turned and the system determines that the driver is taking evasive action.
●A large amount of braking force is applied while the pre-crash braking function is
operating. As the pre-crash braking function will be canceled after the vehicle has
been stopped for approximately 2 seconds, the driver should depress the brake
pedal as necessary.
●If the brake pedal is being depressed, the system may determine that the driver is tak-
ing evasive action and possibly delay the operation timing of the pre-crash braking
function.
*3: Depending on the region in which the vehicle was sold, the pre-crash braking func-
tion may not be available.
■When to disable the pre-crash safety system
In the following situations, disable the system, as it may not operate properly, possibly
leading to an accident resulting in death or serious injury:
●When the vehicle is being towed
●When your vehicle is towing another vehicle
●When transporting the vehicle via truck, boat, train or similar means of transportation
●When the vehicle is raised on a lift with the engine running and the tires are allowed to
rotate freely
●When inspecting the vehicle using a drum tester such as a chassis dynamometer or
speedometer tester, or when using an on vehicle wheel balancer
●When a strong impact is applied to the front bumper or front grille, due to an accident
or other reasons
●If the vehicle cannot be driven in a stable manner, such as when the vehicle has been
in an accident or is malfunctioning
●When the vehicle is driven in a sporty manner or off-road
●When the tires are not properly inflated
●When the tires are very worn
●When tires of a size other than specified are installed
●When tire chains are installed
●GS350/GS200t: When a compact spare tire or an emergency tire puncture repair
kit is used
●GS F: When a spare tire or an emergency tire puncture repair kit is used

The vehicle-to-vehicle distance is set
automatically to long mode when the
engine switch is turned to IGNITION
ON mode.
If a vehicle is running ahead of you, the pr eceding vehicle mark will also be displayed.
Select a distance from the table below. Note that the distances shown corre-
spond to a vehicle speed of 80 km/h (50 mph). Vehicle-to-vehicle distance
increases/decreases in accordance with vehicle speed. When the vehicle is
stopped by system control, the vehicle-to-vehicle distance will be about 3 m
(10 ft.) to 5 m (16 ft.) regardless of the vehicle-to-vehicle distance setting.
After the vehicle ahead of you starts off,
push the lever up.
Your vehicle will also resume follow-up
cruising if the accelerator pedal is
depressed after the vehicle ahead of
you starts off.
