*: If equipped
This function will operate in situations such as the following if an object is detected
in the traveling direction of the vehicle.
â– When traveling at a low speed and the brake pedal is not depressed, or is
depressed late
Parking Support Brake function (static objects)*
If the sensors detect a static object, such as a wall, in the traveling direction of
the vehicle and the system determines that a collision may occur due to the
vehicle suddenly moving forward due to an accidental accelerator pedal oper-
ation, the vehicle moving the unintended direction due to the wrong shift posi-
tion being selected, or while parking or traveling at low speeds, the system will
operate to lessen the impact with the de tected static object and reduce the
resulting damage.

2464-5. Using the driving support systems
â– ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the
brakes are applied suddenly, or if the
brakes are applied while driving on a
slippery road surface
â– Brake assist
Generates an increased level of brak-
ing force after the brake pedal is
depressed when the system detects a
panic stop situation
â– VSC (Vehicle Stability Control)
Helps the driver to control skidding
when swerving suddenly or turning on
slippery road surfaces.
â– Enhanced VSC (Enhanced Vehi-
cle Stability Control)
Provides cooperative control of the
ABS, TRAC, VSC and EPS.
Helps to maintain directional stability
when swerving on slippery road sur-
faces by controlling steering perfor-
mance.
â– Secondary Collision Brake
When the SRS airbag sensor detects a
collision and the system operates, the
brakes and brake lights are automati-
cally controlled to reduce the vehicle
speed and help reduce the possibility
of further damage due to a secondary
collision.
â– TRAC (Traction Control)
Helps to maintain drive power and
prevent the drive wheels from spinning
when starting the vehicle or accelerat-
ing on slippery roads
â– Active Cornering Assist (ACA)
Helps to prevent the vehicle from drift-
ing to the outer side by performing
inner wheel brake control when
attempting to accelerate while turning
â– Hill-start assist control
Helps to reduce the backward move-
ment of the vehicle when starting on an
uphill
â– 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.
â– EPS (Electric Power Steering)
Employs an electric motor to reduce
the amount of effort needed to turn the
Driving assist systems
To keep driving safety and perfor-
mance, the following systems oper-
ate automatically in response to
various driving situations. Be
aware, however, that these systems
are supplementary and should not
be relied upon too heavily when
operating the vehicle.

â– AVS (Adaptive Variable Suspen-
sion System) (if equipped)
By independently controlling the
damping force of the shock absorbers
for each of the 4 wheels according to
the road and driving conditions, this
system helps riding comfort with supe-
rior vehicle stability, and helps good
vehicle posture.
Also, the damping force changes
depending on the selected driving
mode. ( ď‚®P.213)
â– When the TRAC/VSC systems are
operating
The slip indicator light will flash while the
TRAC/VSC systems are operating.
â– Disabling the TRAC system
If the vehicle gets stuck in mud, dirt or snow,
the TRAC system may reduce power from
the engine to the wheels. Pressing the
switch 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 switch.
The “Traction Control Turned Off” will be
shown on the multi-information display.
Press the switch again to turn the

*: PCS (Pre-Collision System) will also be disabled (only Pre-Collision warning is
available). The PCS warning light will
come on and a message will be displayed
on the multi-information display.
(ď‚® P.186)
â– When the message is displayed on the
multi-information display showing that
TRAC has been disabled even if the
switch has not been pressed
TRAC is temporary deactivated. If the
information continues to show, contact your
Lexus dealer.
â– Operating conditions of hill-start assist
control
When all of the following conditions are
met, the hill-start assist control will operate:
â—ŹThe shift lever is in a position other than P
or N (when starting off forward/back-
ward on an upward incline).
â—ŹThe vehicle is stopped.
â—ŹThe accelerator pedal is not depressed.
â—ŹThe parking brake is not engaged.

â– Automatic system cancelation of hill-
start assist control
The hill-start assist control will turn off in any
of the following situations:
â—ŹThe shift lever is shifted to P or N.
â—ŹThe accelerator pedal is depressed.
â—ŹThe parking brake is engaged.
â—Ź2 seconds at maximum elapsed after the
brake pedal is released.
â– Sounds and vibrations caused by the
ABS, brake assist, VSC, TRAC and hill-
start assist control systems
â—ŹA sound may be heard from the engine
compartment when the brake pedal is
depressed repeatedly, when the engine is
started or just after the vehicle begins to
move. This sound does not indicate that a
malfunction has occurred in any of these
systems.
â—ŹAny of the following conditions may
occur when the above systems are oper-
ating. None of these indicates that a mal-
function has occurred.
• Vibrations may be felt through the vehi-
cle body and steering.
• A motor sound may be heard also after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly
after the ABS is activated.
â– Active Cornering Assist operation
sounds and vibrations
When the Active Cornering Assist is oper-
ated, operation sounds and vibrations may
be generated from the brake system, but
this is not a malfunction.
â– EPS operation sound
When the steering wheel is operated, a
motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
â– Automatic reactivation of TRAC and
VSC systems
After turning the TRAC and VSC systems
off, the systems will be automatically re-
enabled in the following situations:
â—ŹWhen the engine switch is turned off
â—ŹIf only the TRAC system is turned off, the
TRAC will turn on when vehicle speed
increases
If both the TRAC and VSC systems are
turned off, automatic re-enabling will not
occur when vehicle speed increases.
â– Secondary Collision Brake operating
conditions
The system operates when the SRS airbag
sensor detects a collision while the vehicle
is in motion.
However, the system does not operate
when the components are damaged.
â– Secondary Collision Brake automatic
cancellation
The system is automatically canceled in any
of the following situations.
â—ŹThe vehicle speed drops to approxi-
mately 6 mph (10 km/h)
â—ŹA certain amount of time elapses during
operation
â—ŹThe accelerator pedal is depressed a
large amount
â– Operating conditions of Active Corner-
ing Assist
The system operates when the following
occurs.
â—ŹTRAC/VSC can operate
â—ŹThe driver is attempting to accelerate
while turning
â—ŹThe system detects that the vehicle is
drifting to the outer side
â—ŹThe brake pedal is released
â– Reduced effectiveness of the EPS sys-
tem
The effectiveness of the EPS system is
reduced to prevent the system from over-
heating 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.
