●Do not turn the steering wheel fully in either direction and hold it there for an
extended period of time.
Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possi ble to avoid damaging
the wheels, underside of the vehicle, etc.
●GS200t: Make sure to idle the engine immediately after high-load driving. Stop the
engine only after the turbocharger has cooled down. ( P. 225)
Failure to do so may cause damage to the turbocharger.

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.
