celed. However, when the operation con-
ditions are met again, operation of the
function is automa tically restored.
(  P.241)
●If the operation conditions ( P.241) are
no longer met while the lane centering
function is operating, the steering wheel
may vibrate and the buzzer may sound to
indicate that the function has been tem-
porarily canceled. However, if the “Alert”
customization setting is set to ,
the system will notify the driver by vibrat-
ing the steering wheel instead of sound-
ing the buzzer.
●If the operating conditions ( P.241) are
no longer met, the lane change assist
function will be canceled. (vehicles with
Lexus Safety System + A)
If a message urging operation of the steer-
ing wheel is displayed, operate the steering
wheel.
■Steering assist function/lane centering
function
●Depending on the vehicle speed, lane
departure situation, road conditions, etc.,
the driver may not feel the function is
operating or the function may not oper-
ate at all.
●The steering control of the function is
overrided by the driver’s steering wheel
operation.
●When the vehicle speed is approximately
31 mph (50 km/h) or less, the warning
display of the lane ce ntering function will
not operate.
●Do not attempt to test the operation of the steering assist function.
●The steering assist function may operate
when attempting to cut closely in front of
another vehicle while
changing lanes.
■Lane departure alert function
●The warning buzzer may be difficult to
hear due to external noise, audio play-
back, etc. Also, it may be difficult to feel
steering wheel vibrations due to the road
conditions, etc.
●If the edge of the course* is not clear or
straight, the lane departure alert function
may not operate.
●It may not be possible for the system to
determine if there is a danger of a colli-
sion with a vehicle in an adjacent lane.
●Do not attempt to test the operation of
the lane departure alert function.
●This function may operate if, when chang-
ing lanes, your vehicle cuts closely in front

Depending on the vehicle speed, vehicle
condition, road conditions, or conditions of
the area around the vehicle, the lane
change assist function may not operate or it
may be difficult to recognize that it has
operated.
If steering control oper ation is excessive or
insufficient, it can be corrected by the
driver’s operation of the steering wheel.
In situations such as the following, the lane
change assist function may be canceled:
●When the system no longer detects white
(yellow) lane lines
●When the turn signal lever is operated
fully (right/left turn position)
●When the vehicle speed is outside of the
operational range of the function
●When the system detects operation of
the steering wheel, brake or accelerator
pedal by the driver

Driving
■The system can be operated when
●The power switch is in ON mode.
●Intuitive parking assist function is on.
●The vehicle speed is less than about 6
mph (10 km/h).
●A shift position other than P is selected.
■Setting the buzzer volume
The buzzer volume can be adjusted on the
multi-information display. ( P.264)
■If “Parking Assist Unavailable Clean
Parking Assist Sensor” is displayed on
the multi-inform ation display
A sensor may be covered with ice, snow, dirt, etc. Remove the ice, snow, dirt, etc.,
from the sensor to return the system to nor-
mal.
Also, due to ice forming on a sensor at low
temperatures, a warn
ing message may be
displayed or the sensor may not be able to
detect an object. Once the ice melts, the
system will return to normal.
■Sensor detection information
●The following situations may occur
during use.
• The sensors may be able to only detect objects near the fron t and rear bumpers.
• Depending on the shape of the object
and other factors, the detection distance
may shorten, or detection may be impos-
sible.
• There will be a short delay between object detection and di splay. Even at low
speeds, there is a possibility that the
object will come within the sensor’s
detection areas befo re the display is
shown and the warning beep sounds.
• It might be difficult to hear the buzzer due to the volume of the audio system or air
flow noise of the air conditioning system.
• It may be difficult to hear the buzzer if buzzers for other systems are sounding.
■Conditions under wh ich the function
may not function correctly
Certain vehicle conditions and the sur-
rounding environment may affect the ability
of a sensor to correctly detect objects. Par-
ticular instances where this may occur are
listed below.
●There is dirt, snow or ice on a sensor.
(Cleaning the sensors will resolve this
problem.)
●A sensor is frozen. (Thawing the area will
resolve this problem.)
In especially cold weather, if a sensor is
frozen the sensor display may be dis-
played abnormally, or objects, such as a
wall, may not be detected.
●A sensor is covered in any way.
●When a sensor or the area around a sen-
sor is extremely hot or cold.
●On an extremely bumpy road, on an
incline, on gravel, or on grass.
WARNING
●If the area around a sensor collides
with something, or is subjected to
strong impact.
●If the bumper or grille collides with
something.
●If the display flashes or is displayed
continuously and a buzzer does not
sound, except when the mute function
has been turned on.
●If a display error occurs, first check the
sensor.
If the error occurs even when there is
no ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.
■Notes when washing the vehicle
Do not apply intensive bursts of water or
steam to the sensor area.
Doing so may result in the sensor mal-
functioning.
●When using a high pressure washer to
wash the vehicle, do not spray the sen-
sors directly, as doing so may cause a
sensor to malfunction.
●When using steam to clean the vehicle,
do not direct steam too close to the
sensors as doing so may cause a sen-
sor to malfunction.

etc., from the attached to the rear bumper
around the sensors to normal.
Additionally, the function may not function
normally when used in extremely hot or
cold environments.
■Rear side radar sensors
 P.260
■Operation of the RCTA function
The RCTA function uses rear side 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 indi cators and sounding a
buzzer.

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 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 certai n conditions, the
driver’s own visual confirmation of safety
is necessary. Over re liance on this func-
tion may lead to an accident resulting
death or serious injury.
