The current TVD control mode will be
displayed on the meters.
STANDARD mode
This is the default mode and pro-
vides 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 di stribution of driving force between the
right and left rear wheels. ( →P. 117)
TVD (Torque Vectoring Differential)∗
∗
: If equipped
The TVD system distributes driving force (torque) between the right an\
d 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. 580) 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
The TVD fluid temperature may become excessively high when driving for a long time
under extremely high load conditions. In th is case, a warning message will be displayed
on the multi-information display. ( →P. 581)

3324-6. Driving tips
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is frozen. Pour
warm water over the frozen area to me lt the ice. Wipe away the water imme-
diately to prevent it from freezing.
●To ensure proper operation of the c limate control system fan, remove any
snow that has accumulated on the air inlet vents in front of the windshield.
●Check for and remove any excess ice or snow that may have accumulated on
the exterior lights, vehicle’s roof, chassi s, around the tires or on the brakes.
●Remove any snow or mud from the bottom of your shoes before getting in the
vehicle.
Accelerate the vehicle slowly, keep a sa fe distance between you and the vehicle
ahead, and drive at a reduced spee d suitable to road conditions.
●Park the vehicle and move the shift lever to P without setting the parking
brake. The parking brake may freeze up, preventing it from being released. If
the vehicle is parked without setting the parking brake, make sure to block the
wheels.
Failure to do so may be dangerous because it may cause the vehicle to move
unexpectedly, possibly leading to an accident.
●If the vehicle is parked without setting the parking brake, confirm that the shift
lever cannot be moved out of P
*.
*: The shift lever will be locked if it is atte mpted to be shifted from P to any other posi-
tion without depressing the brake pedal. If the shift lever can be shifted from P, there
may be a problem with the shift lock sy stem. Have the vehicle inspected by your
Lexus dealer immediately.
