The wipers can be used as intermittent windshield wipers, which operate regard-
less of vehicle speed or amount of raindrops. The intermittent windshield wip er
operation can be switched when the vehicle is stopped and the wiper is off. The
wiper operation cannot be switched during 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 op eration will be switched from low speed to
intermittent operation only when 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.
WARNING
■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 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.

2824-4. Refueling
GS350_200t_GS F_OM_OM30F83E_(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. 632
■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
WARNING
■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.

GS350_200t_GS F_OM_OM30F83E_(EE)
●Side road speed signs may be detected and di splayed (if positioned in sight of the cam-
era sensor) while the vehicle is traveling on the main road.
●Roundabout exit road speed signs may be detected and displayed (if positioned in sight
of the camera sensor) while traveling on a roundabout.
●On some models: The speed information displayed on the meter and t hat displayed on
the navigation system may be different due to the navigation system using map data.
■When driving vehicle in country with different speed unit
Since RSA recognizes signs based on the set un it of the meter, it is necessary to change
the set unit of the meter. Adjust the set unit of the meter to the speed unit of signs in the
current location. ( P. 641)
■Turning the system on/off
■Speed limit sign display
If the engine switch was last turned off while a speed limit sign was displayed on the multi-
information display, the same sign displays again when the engine switch is turned to
IGNITION ON mode.
■Customization
Setting (e.g. speeding warning threshold) can be changed.
(Customizable feature: P. 634)

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 preceding 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.

TVD (Torque Vectoring Differential)
With the engine switch in IGNITION
ON mode, pressing the TVD switch
changes the TVD control mode.
The current TVD control mode will be
displayed on the meters.
STANDARD mode
This is the default mode and provides an
optimum balance of driving agility and
stability.
SLALOM mode
This mode emphasizes enhanced steer-
ing response.
TRACK mode
This mode emphasizes stability for high
speed sporty driving.
The multi-information display shows the distribution of driving force b etween the
right and left rear wheels. (  P. 134)
: If equipped
The TVD system distributes driving fo rce (torque) between the right and left
rear wheels automatically. This system contributes to enhanced steering
response while cornering and increased traction when exiting a corner, pro-
viding an agile driving experience.

■Automatic cancelation of the selected TVD control mode
SLALOM and TRACK mode are canceled when the engine switch is turned off. When
the engine switch is turned to IGNITION ON mode, the TVD system will be in STAN-
DARD mode.
■Automatic disabling of the TVD system
If a malfunction is detected in the TVD sy stem, a warning message will be displayed on
the multi-information display ( P. 524) and the TVD system will be disabled automati-
cally. If the system is disabled, driving force will not be distributed by the TVD but through
normal differential operation.
■To protect the system
If the TVD fluid temperature becomes excessi vely high due to driving for a long time
under extremely high load conditions, a warning message will be displayed on the multi-
information display. ( P. 524)
WARNING
■Cautions regarding the use of the system
The driver is solely responsible for safe driv ing. Do not overly rely on the TVD system.
Always drive safely, taking care to observe your surroundings.
