• When the sensor is misaligned due to a strong impact to the sensor or its sur-
rounding area
• When the distance between your vehicle and a guardrail, wall, etc. that enters the
detection area is short
• When driving up an d down consecutive
steep inclines, such as hills, dips in the
road, etc.
• When vehicle lanes are narrow, or when driving on the edge of a lane, and a vehi-
cle traveling in a lane other than the adja-
cent lanes enters the detection area
• When driving on roads with sharp bends, consecutive curves, or uneven surfaces
• When the tires are slipping or spinning
• When the distance between your vehicle and a following vehicle is short
• When an accessory (such as a bicycle carrier) or towing eyel et is installed to the
rear of the vehicle
■Operation of the RCTA function
The RCTA function uses radar sensors to detect vehicles approaching from the
right or left at the rear of the vehicle and alerts the driver of the presence of such
vehicles by flashing the outside rear view mirror indicators and sounding a buzzer.

Detection areas of approaching vehicles
■RCTA icon display
When a vehicle approaching from the
right or left at the rear of the vehicle is
detected, the following will be dis-
played on the monitor screen.
WARNING
■Cautions regarding the use of the
function
The driver is solely responsible for safe
driving. Always drive safely, taking care
to observe your surroundings.
The BSM function is a supplementary
function which alerts the driver that a
vehicle is in a blind spot of the outside
rear view mirrors or is approaching rap-
idly from behind into a blind spot. Do not
overly rely on the BSM function. As the
function cannot judge if it is safe to
change lanes, over re liance could lead to
an accident resulting in death or serious
injury.
As the system may not function correctly
under certain conditio ns, the driver’s own
visual confirmation of safety is necessary.

WARNING
■Cautions regarding the use of the
function
The driver is solely responsible for safe
driving. Always driv e safely, taking care
to observe your surroundings.
The RCTA function is only a supplemen-
tary function which alerts the driver that a
vehicle is approaching from the right or
left at the rear of the vehicle. As the
RCTA function may not function cor-
rectly under certain conditions, the
driver’s own visual confirmation of safety
is necessary. Over reli ance on this func-
tion may lead to an accident resulting
death or serious injury.
Active rear wing*
The vehicle is equipped with an
active rear wing that operates auto-
matically while the vehicle is being
driven. This active rear wing
enhances aerodynamic perfor-
mance, especially at high speeds,
contributing to a more stable ride.
The active rear wing can be con-
trolled manually using a switch.

■LDH (Lexus Dynamic Handling
system) (if equipped)
Provides integrated control of the
VGRS, DRS and EPS. Contributes to
turning characteristics at low speeds,
responsiveness at medium speeds and
safety at high speeds by controlling the
steering angle of the front and rear
wheels in accordance with the steering
wheel operation and vehicle speed
■VDIM (Vehicle Dynamics Inte-
grated Management)
Provides integrated control of the
ABS, brake assist, TRAC, VSC, hill-
start assist control, EPS, VGRS (if
equipped) and DRS (if equipped) sys-
tems
Helps to maintain vehicle stability when
swerving on slippery road surfaces by
controlling the brakes, engine system> output, steering assist (if
equipped), and steering ratio (if
equipped)
■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 redu ce the possibility
of further damage due to a secondary
collision
■When the
TRAC/VSC/ABS/VGRS*/DRS* sys-
tems are operating
The slip indicator light will flash while the TRAC/VSC/ABS/VGRS
*/DRS* systems
are operating.
*: Only when controlled by the VDIM sys-
tem.
■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 sys-
tem 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.
“Traction Control Turned Off” will be shown
on the multi-information display.
Press the switch again to turn the sys-
tem back on.

from its straight forward position, but it will
return when the system restarts.
●When the steering wheel is operated for
an extended period of time while the vehicle is stopped or is moving very
slowly
(on vehicles with LDH, DRS is disabled
together with VGRS)
●When the steering wheel has been held
fully to the left or right
The center position of the steering wheel
may change when VGRS is disabled. How-
ever, the position will return to normal after
VGRS is reactivated.
■When the 12-volt battery is discon-
nected (vehicles with VGRS)
The steering wheel may move from its
straight forward position, but this will be
corrected automatically when driving.
■Sounds and vibrations caused by the
ABS, brake assist, VSC, TRAC, hill-start
assist control and VGRS systems
●A 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.

occur when the above systems are oper-
ating. None of these indicates that a mal-
function has occurred.
• Vibrations may be felt through the vehicle
body and steering.

■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.
■EPS, VGRS and DRS 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 TRAC and
VSC systems
After turning the TRAC 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 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.
■Operating conditions of Active Corner-
ing Assist
The system operates when the following
occurs.
●TRAC/VSC can operate
●The driver is attempting to accelerate
while turning
●The system detects th at the vehicle is
drifting to the outer side

mately 6 mph (10 km/h)
●A certain amount of time elapses during
operation
●The accelerator pedal is depressed a
large amount
■If “Secondary Collision Brake system
Malfunction” is displayed on the multi-
information display
The system may be ma lfunctioning. Have
the vehicle inspected at your Lexus dealer.
■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, re frain from excessive
steering input or stop the vehicle and turn
the engine off. The EPS sys-
tem should return to normal within 10 min-
utes.
WARNING
■The ABS does not operate effectively
when
●The limits of tire gripping performance
have been exceeded (such as exces-
sively worn tires on a snow covered
road).
●The vehicle hydroplanes while driving
at high speed on wet or slick roads.
■Stopping distance when the ABS is
operating may exceed that of normal
conditions
The ABS is not designed to shorten the
vehicle’s stopping di stance. Always main-
tain a safe distance from the vehicle in
front of you, especially in the following
situations:
