■Before using dynamic radar cruise control
Do not overly rely on vehicle-to-vehicle distance control mode.
Be aware of the set speed. If automatic deceleration/acceleration is not appropriate,
adjust the vehicle speed, as well as the distance between your vehicle and vehicles
ahead by applying the brakes, etc.
■Cautions regarding the driving assist systems
Observe the following precautions.
Failure to do so may cause an accident resulting in death or serious injury.
●Assisting the driver to measure following distance
The dynamic radar cruise control is only in tended to help the driver in determining
the following distance between the driver’s own vehicle and a designated vehicle
traveling ahead. It is not a mechanism that al lows careless or inattentive driving, and it
is not a system that can assist the driver in low-visibility conditions. It is still necessary
for driver to pay close attention to the vehicle’s surroundings.
●Assisting the driver to judge proper following distance
The dynamic radar cruise control determines whether the following distance
between the driver’s own vehicle and a designated vehicle traveling ahead is appro-
priate or not. It is not capable of making an y other type of judgement. Therefore, it is
absolutely necessary for the driver to remain vigilant and to determine whether or not
there is a possibility of danger in any given situation.
●Assisting the driver to operate the vehicle
The dynamic radar cruise control has no capa bility to prevent or avoid a collision with
a vehicle traveling ahead. Therefore, if there is ever any danger, the driver must take
immediate and direct control of the vehicl e and act appropriately in order to ensure
the safety of all involved.
■To avoid inadvertent dynamic radar cruise control activation
Switch the dynamic radar cruise control off using the “ON/OFF” button when not in
use.

■Dynamic radar cruise control with full-speed range can be set when
●The shift lever is in D.
●Vehicle speed is above approximately 30 mph (50 km/h).
■Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After accelerating, the
set speed resumes. However, during vehicle-to-vehicle distance control mode, the vehi-
cle speed may decrease below the set speed in order to maintain the distance to the pre-
ceding vehicle.
■Automatic cancelation of vehicle- to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the following situ-
ations:
●VSC is activated.
●TRAC is activated for a period of time.
●When the VSC or TRAC system is turned off by pressing the VSC OFF switch.
●The sensor cannot detect properly beca use it is obstructed in some way.
●Brake automatically operated for long peri ods of time, such as traffic jams, etc.
●The parking brake is operated.
●The vehicle is stopped by system control on a steep incline.
●Pre-collision braking is activated.
●The following are detected when the vehicle has been stopped by system control:
• The driver is not wearing a seat belt.
• The driver’s door is opened.
• The back door or hood is opened.
When vehicle-to-vehicle distance control mo de is automatically canceled in the follow-
ing situations, “Radar Cruise Control Unavaila ble” will be displayed on the multi-infor-
mation display:
●Actual vehicle speed falls below approximately 25 mph (40 km/h) when there are no
vehicles ahead.
●The preceding vehicle leaves the lane when your vehicle is following at a vehicle speed
below 25 mph (40 km/h). Otherwise, the se nsor cannot properly detect the vehicle.
●The windshield wipers are operating at high speed (when the wiper switch is set to the
“AUTO” mode or the high speed wiper operation position).
If vehicle-to-vehicle distance control mode is automatically canceled for any other rea-
son, there may be a malfunction in the system. Contact your Lexus dealer.

■Automatic cancelation of constant speed control mode
Constant speed control mode is automatically canceled in the following situations:
●Actual vehicle speed is more than approximately 10 mph (16 km/h) below the set vehi-
cle speed.
●Actual vehicle speed falls below approximately 25 mph (40 km/h).
●VSC is activated.
●TRAC is activated for a period of time.
●When the VSC or TRAC system is turned off by pressing the VSC OFF switch.
●Pre-collision braking is activated.
■Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-vehicle dis-
tance control mode operates properly. (Some obstructions, such as snow, ice and plastic
objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control with full-speed range is canceled if an obstruction is
detected.
■Warning messages and buzzers for dynamic ra dar cruise control with full-speed range
Warning messages and buzzers are used to indicate a system malfunction or to inform
the driver of the need for caution while driving. If a warning message is shown on the
multi-information display, read the message and follow the instructions.

◆Dynamic Torque Control AWD system (if equipped)
Automatically switches from front-wheel drive to all-wheel drive (AWD)
according to the driving conditions, he lping to ensure reliable handling and
stability. Examples of conditions wher e the system will switch to AWD are
when cornering, going uph ill, starting off or accelerating, and when the road
surface is slippery due to snow, rain, etc.
◆AVS (Adaptive Variable Suspension system) (if equipped)
By independently controlling the dampin g force of the shock absorbers for
each of the 4 wheels according to the road and driving conditions, this system
helps riding comfort with superior st eering stability, and helps good vehicle
posture. When SPORT S+ mode is selected by the driving mode select
switch, the damping force is suitable for sporty driving. ( P. 2 9 5 )

If the vehicle gets stuck in mud, dirt or snow, the TRAC 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 TRAC 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 TRAC and VSC systems
To turn the TRAC and VSC systems off, press and hold for more than 3 seconds
while the vehicle is stopped.
The VSC OFF indicator will come on and the “Traction Control Turned Off” will be
shown on the multi- information display.
*
Press again to turn the systems back on.
*: On vehicles with pre-collision system, pre-collision brake assist and pre-collision
braking will also be disabled. The PCS warn ing light will come on and the message will
be shown on the multi-information display. ( P. 3 0 6 )
■When the message is displayed on the mu lti-information display showing that TRAC
has been disabled even if the has not been pressed
TRAC and hill-start assist control cannot be operated. Contact your Lexus dealer.

PCS (Pre-Collision System)
◆Pre-collision warning
When a high possibility of a frontal
collision is detected, a buzzer
sounds and a message is shown on
the multi-information display to urge
the driver to take evasive action.
◆Pre-collision brake assist
When there is a high possibility of a frontal collision, the system applies greater brak-
ing force in relation to how strongly the brake pedal is depressed.
◆Pre-collision braking
When there is a high possibility of a fronta l collision, the system warns the driver using
warning display and buzzer. If the system determines that a collision is unavoidable,
the brakes are automatically applied to reduce the collision speed.
◆Suspension control (vehicles with Ad aptive Variable Suspension system)
When the system determines that there is a high possibility of a frontal colli-
sion, the operation of Adaptive Variable Suspension system ( P. 2 9 8 ) o p t i -
mally controls the damping force of the shock absorber.
: If equipped
When the radar sensor detects possibilit y of a frontal collision, brakes are
automatically engaged to lessen im pact as well as vehicle damage.
The alert timing for the pre-collision system can be changed or turned ON/
OFF, as necessary, by operating the switch. ( P. 304)

*:Default setting
■Turning off the pre-collision system
Press the PCS switch for 3 seconds
or more seconds.
The PCS warning light turns on and a
message is shown on the multi-infor-
mation display.
To turn on the system, press the PCS
switch again. The system is set to ON
each time the engine switch is turned
to IGNITION ON mode.
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.
