Sport mode•SPORT S mode
Assists acceleration response by controlling the transmission and engine.
When not in SPORT S mode, if the driving mode select switch is turned to the
right, the “SPORT S” indicator comes on in the meter.
•SPORT S+ mode
Provides earlier downshift timing than SPORT S mode in order to maintain
a high engine speed and provides fa ster gear changes. This mode also
changes the steering feel and VDIM co ntrol, making it suitable for power-
ful sporty driving.
When in SPORT S mode, if th e driving mode select switch is turned to the right,
the “SPORT S+” indicator comes on in the meter.
■Operation of the air conditioning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the air condi-
tioning system to enhance fuel efficiency ( →P. 394). To improve air conditioning perfor-
mance, adjust the fan speed or turn off Eco drive mode.
■Automatic operation of the seat heater during Eco drive mode
Eco drive mode controls the heating operation and fan speed of the air conditioning sys-
tem to enhance fuel efficiency. If the driving mode select switch is switched to Eco drive
mode in cold temperatures, the seat heater will be automatically operated to assist heat-
ing performance.
■Automatic deactivation of sport mode and customized mode
If the engine switch is turned off after dr iving in sport mode or customized mode, the
drive mode will be changed to normal mode.
■Driving mode pop-up display (12.3-inch display only)
When the driving mode is changed, the selected driving mode will be temporarily dis-
played on the side display. ( →P. 3 9 2 )

Interior features
GS350_200t_GS F_OM_OM30E87E_(EE)
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the outside/recircu-
lated air mode button to the recirculated air mode. This is effective in preventing out-
side air from entering the vehicle interior. During cooling operation, setting the
recirculated air mode will also cool the vehicle interior effectively.
●Outside/recirculated air mode may automatically switch depending on the tempera-
ture setting or the inside temperature.
■Automatic mode for air intake control
In automatic mode, the system detects exhaust gas and other pollutants and automati-
cally switches between outside air and recirculated air modes.
When the dehumidification function is off, and the fan is operating, turning automatic
mode on will activate the dehumidification function.
■Operation of the air conditioning system in Eco drive mode
In the Eco drive mode, the air conditioning system is controlled as follows to prioritize
fuel efficiency:
●Engine speed and compressor operation controlled to restrict heating/cooling capac-
ity
●Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
●Adjust the fan speed
●Turn off Eco drive mode (→P. 3 5 6 )
■When the S-FLOW mode operates
If air flows to the driver’s seat only, the temperature setting for the front passenger’s seat
is not displayed.
■When the outside temperature is low
The dehumidification function may not operate even when “A/C” on the option control
screen is selected.
■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the outside air mode.
●During use, various odors from inside and outside the vehicle may enter into and accu-
mulate in the air conditioning system. This may then cause odor to be emitted from the
vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode prior
to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time immediately after the air conditioning system is started in automatic mode.

4446-3. Do-it-yourself maintenance
GS350_200t_GS F_OM_OM30E87E_(EE)
WA R N I N G
The engine compartment contains many mechanisms and fluids that may move suddenly,
become hot, or become electrically energized. To avoid death or serious injury, observe
the following precautions.
■When working on the engine compartment
●Keep hands, clothing and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, radiator, exhaust manifold, etc. right after driving
as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the engine
compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel or
the battery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous and corro-
sive sulfuric acid.
●Take care because brake fluid can harm your hands or eyes and damage painted sur-
faces. If fluid gets on your hands or in your eyes, flush the affected area with clean
water immediately. If you still experience discomfort, consult a doctor.
■When working near the electric cooling fans or radiator grille
Be sure the engine switch is off.
With the engine switch in IGNITION ON mode, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant temperature is high.
( → P. 4 6 0 )
■Safety glasses
Wear safety glasses to prevent flying or fallin g material, fluid spray, etc. from getting in
your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear due to dirt
in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear or when
the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.
