NOTICE
■If you get a flat tire while driving
A flat or damaged tire may cause the follo
wing situations. Hold the steering wheel
firmly and gradually depress the brak e pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( P. 4 9 1 , 5 0 2 )
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may cause the
following serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to have
your Lexus dealer check the following:
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, transmission,
transfer (AWD models), differential, etc.
●Lubricant condition for the propeller shaft, bearings and suspension joints (where
possible), and the function of all joints, bearings, etc.

GS350_200t_GS F_OM_OM30E86U_(U)4-5. Using the driving support systems
TVD (Torque Vectoring Differential) (GS F)
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
steering response.
TRACK mode
This mode emphasizes stability for
high speed sporty driving.
The multi-information display shows the distribution of driving force between the
right and left rear wheels. (
P. 113)
The TVD system distributes driving force (torque) between the right and left
rear wheels automatically. This syst em 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 system, a warn ing message will be displayed on
the multi-information display ( P. 459) 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 excessively high due to driving for a long time
under extremely high load conditions, a warn ing message will be displayed on the multi-
information display. ( P. 4 5 9 )
WA R N I N G
■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.
