◆Pre-collision warning
When a high possibility of a frontal
collision is detected, the pre-colli-
sion system warning light flashes, a
buzzer sounds and a message is
shown on the multi-information dis-
play to urge the driver to take eva-
sive action.
◆Pre-collision brake assist
When there is a high possibility of a frontal collision, the system applies
greater braking force in relation to ho w strongly the brake pedal is depressed.
The system may not warn the driver using a warning light, warning display and
buzzer when the system detects and judges braking operations.
◆Pre-collision braking
When there is a high possibility of a frontal collision, the system warns the
driver using a warning light, warning di splay and buzzer. If the system deter-
mines that a collision is unavoidable, the brakes are automatically applied to
reduce the collision speed.
◆Suspension control (if equipped)
When the system determines that there is a high possibility of a frontal colli-
sion, the operation of Adaptive Variable Suspension System ( P. 288) opti-
mally controls the damping force of the shock absorber.
PCS (Pre-Collision System)
: If equipped
When the radar sensor detects the possibility of a frontal collision, brakes are
automatically engaged to lessen im pact as well as vehicle damage.
The pre-collision system can be turned on and off as necessary by operating
the switch. ( P. 2 9 6 )

◆Steering control (if equipped)
When the system determines that there is a high possibility of a frontal colli-
sion while the steering wheel is being operated, the LDH (Lexus Dynamic
Handling) system controls the steering an gle of the front and rear wheels and
torque applied to the steering wheel to enhance the steering wheel operation
response.
Enabled
Disabled
The pre-collision system warning light
comes on when pre-collision system is
disabled.
The radar sensor detects vehicles or
other obstacles on or near the road
ahead and determines whether a colli-
sion is imminent based on the position,
speed, and heading of the obstacles.

■Handling the radar sensor
Blind Spot Monitor sensors are installed behind the left and right sides of the rear
bumper respectively. Observe the following to ensure the Blind Spot Monitor can
function correctly.
●Do not subject a sensor or its surrounding area on the rear bumper to a strong
impact.
If a sensor is moved even slightly off po sition, the system may malfunction and vehi-
cles may not be detected correctly.
In the following situations, have your vehicle inspected by your Lexus dealer.
• A sensor or its surrounding area is subject to a strong impact.
• If the surrounding area of a sensor is sc ratched or dented, or part of them has
become disconnected.
●Do not disassemble the sensor.
●Do not attach stickers to the sensor or surrounding area on the rear bumper.
●Do not modify the sensor or surrounding area on the rear bumper.
●Do not paint the rear bumper any color other than an official Lexus color.
●Keep the sensors and the surrounding areas
on the rear bumper clean at all times.
If a sensor or its surrounding area on the rear
bumper is dirty or covered with snow, the
Blind Spot Monitor may not operate and a
warning message (P. 555, 556) will be dis-
played. In this situation, clear off the dirt or
snow and drive the vehicle with the operation
conditions of the BSM function ( P. 3 0 8 )
satisfied for approximately 10 minutes. If the
warning message does not disappear, have
the vehicle inspected by your Lexus dealer.

Operate the active rear wing switch to raise/retract the active rear wing manu-
ally. (The active rear wing retracts when it is raised and raises when retracted.)
■Operation by switch
*: Press and hold the switch until the indicator turns off. If the switch is released while the
active rear wing is moving, it will return to the raised position automatically.
■The active rear wing can be operated when
●The engine switch is in IGNITION ON mode.
●The trunk is closed.
■Conditions which stop the operation of the active rear wing
In the following situations operatio n of the active rear wing will stop:
●The engine switch is turned off while the active rear wing is operating.
●The trunk is opened while the active rear wing is operating.
●The raising operation of the active rear wing is interrupted by an object, etc.
●The active rear wing is operated in an unus ual manner causing it to stop at an irregular
position.
In such cases, pressing the active rear wing switch will fully raise the active rear wing. Or,
begin driving the vehicle and the active rear wing will raise automatically when the vehi-
cle speed reaches 16 mph (25 km/h).
■Restoring automatic operation after the active rear wing is operated manually
If the active rear wing is operated manually, automatic operation will resume according
to the vehicle speed.
■When there is a malfunction in the system
A warning message will be displayed on the multi-information display. (P. 5 6 1 )
■Customization
The active rear wing can be held at the raised position or retracted position.

■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. 558) 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. 5 5 8 )

■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.
