Normal mode
Provides an optimal balance of fuel ec onomy, quietness, and dynamic perfor-
mance. Suitable for city driving.
Press the switch to change the driving mode to normal mode when Eco drive mode or sport mode is selected.
Eco drive mode
Helps the driver accelerate in an eco-friendly manner and improve fuel econ-
omy through moderate throttle characteristics and by controlling the opera-
tion of the air conditioning system (heating/cooling).
When not in Eco drive mode, if the driving mode select switch is turned to the left, the
Eco drive mode indicator will come on.
Sport mode
Controls the transmission and engine to provide quick, powerful acceleration.
This mode also changes the steering feel, making it suitable for when agile
driving response is desired, such as when driving on roads with many curves.
When not in sport mode, if the driving mode se lect switch is turned to the right, the “SPORT” indicator will comes on.

■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 . To improve air conditioning performance, adjust the fan speed or turn off Eco drive mode.
■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. 533)

Press the switch.
The torque of the engine is distributed to the rear wheels to the maximum extent pos-
sible in accordance with driving conditions.
Pressing the switch again cancels all-wheel drive lock mode and returns the Dynamic Torque Control AWD system to normal mode. ( P. 423)
■All-wheel drive lock mode can be operated when
The engine switch is in IGNITION ON mode.
■Automatic release for the all-wheel drive lock mode
●All-wheel drive lock mode is canceled when the brakes are applied to ensure the ABS and VSC systems operate effectively.
●All-wheel drive lock mode is canceled when the vehicle speed exceeds 40 km/h(25 mph).
All-wheel drive lock switch (AWD models)
All-wheel drive lock mode can be used when a large amount of drive power
needs to be applied to all the wheels, such as when the vehicle gets stuck in
mud and you need to free it.

◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn the
steering wheel
◆Dynamic Torque Control AWD system (AWD models)
Automatically switches from front-wheel drive to all-wheel drive (AWD)
according to the driving conditions, helping to ensure reliable handling and
stability. Examples of conditions where the system will switch to AWD are
when cornering, going uphill, starting off or accelerating, and when the road
surface is slippery due to snow, rain, etc.
◆Adaptive Variable Suspension System (if equipped)
Controls the damping force of the shock absorber of each wheel according to
the road and driving conditions, helping achieve a comfortable ride, excellent
driveability and a high level of stability.
If SPORT S+ mode is selected using the driving mode select switch, the
damping force will become more suitable for sporty driving. ( P. 418)
◆VDIM (Vehicle Dynamics Integrated Management) (if equipped)
Provides integrated control of the ABS, brake assist, TRC, VSC, hill-start
assist control and EPS systems
Helps to maintain vehicle stability when swerving on slippery road surfaces by
controlling the brakes and engine output
◆Emergency brake signal
When the brakes are applie d suddenly, the stop lights automatically flash to
alert the vehicle behind.

The slip indicator light will flash while
the TRC/VSC systems are operating.
If the vehicle gets stuck in mud, dirt or snow, the TRC system may reduce power
from the engine to the wheels. Pressing to turn the system off may make
it easier for you to rock the vehicle in order to free it.
To turn the TRC system off, quickly
press and release .
The “Traction Control Turned Off” will
be shown on the multi-information dis-
play. Press again to turn the sys-
tem back on.

■Turning off both TRC and VSC systems
To turn the TRC and VSC systems off, pr ess and hold for more than 3 seconds
while the vehicle is stopped.
The VSC OFF indicator light will come on an d the “Traction Control Turned Off” will be
shown on the multi-information display.
*
Press again to turn the systems back on.
*: On vehicles with PCS (Pre-Crash Safety system), pre-crash brake assist and pre-
crash braking will also be disabled. ( P. 312)
■When the message is displayed on the mult i-information display showing that TRC has
been disabled even if the VSC OFF switch has not been pressed
TRC cannot be operated. Contact any authoriz ed Lexus dealer or repairer, or another
duly qualified and equipped professional.
■Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assist control will operate:
●The shift lever is in a position other than P or N (when starting off forward/backward on
an upward incline).
●The vehicle is stopped
●The accelerator pedal is not depressed
●The parking brake is not engaged
■Automatic system cancelation of hill-start assist control
The hill-start assist control will turn off in any of the following situations:
●The shift lever is shifted to P or N
●The accelerator pedal is depressed
●The parking brake is engaged
●Approximately 2 seconds elapse after the brake pedal is released
■Sounds and vibrations caused by the ABS, brake assist, TRC, VSC and hill-start assist
control systems
●A sound may be heard from the engine compartment when the brake pedal is
depressed repeatedly, when the engine is st arted or just after the vehicle begins to
move. This sound does not indicate that a malfunction has occurred in any of these sys-
tems.
●Any of the following conditions may occu r when the above systems are operating.
None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard also after the vehicle comes to a stop.
• The brake pedal may pulsate slig htly after the ABS is activated.
• The brake pedal may move down slig htly after the ABS is activated.
■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be heard.
This does not indicate a malfunction.

■Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automatically re-enabled in the following situations:
●When the engine switch is turned off
●If only the TRC system is turned off, the TR C will turn on when vehicle speed increases
If both the TRC and VSC systems are turned off, automatic re-enabling will not occur
when vehicle speed increases.
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is redu ced to prevent the system from overheating
when there is frequent steering input over an extended period of time. The steering wheel may feel heavy as a result. Should this occur, refrain from excessive steering input or stop the vehicle and turn the engine off. The EPS system should return to normal
within 10 minutes.
■Operating conditions of emergency brake signal
When the following three conditions are me t, the emergency brake signal will operate:
●The emergency flashers are off.
●Actual vehicle speed is over 55 km/h (35 mph).
●The brake pedal is depressed in a manner that cause the system to judge from the vehi-
cle deceleration that this is a sudden braking operation.
■Automatic system cancelation of emergency brake signal
The emergency brake signal will turn of f in any of the following situations:
●The emergency flashers are turned on.
●The brake pedal is released.
●The system judges from the vehicle deceleration that is not a sudden braking operation.
