■Dynamic radar cruise control with
full-speed range can be set when
●The shift position is in D.
●The desired set spee d can be set when
the vehicle speed is approximately 20
mph (30 km/h) or more.
(However, when the vehicle speed is set
while driving at below approximately 20
mph [30 km/h], the set speed will be set
to approximately 20 mph [30 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 vehi-
cle-to-vehicle distance control mode, the
vehicle speed may decrease below the set
speed in order to maintain the distance to
the preceding vehicle.
■When the vehicle stops while follow-up
cruising
●Pressing the “+RES” switch while the
vehicle ahead stops w ill resume follow-up
cruising if the vehicle ahead starts off
within approximately 3 seconds after the
switch is pressed.
●If the vehicle ahead starts off within 3 sec-
onds after your vehicle stops, follow-up
cruising will be resumed.
■Automatic cancelation of vehi-
cle-to-vehicle distance control mode
Vehicle-to-vehicle dist ance 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.
●When snow mode is set.
●The sensor cannot detect correctly
because it is covered in some way.
●When the brake control or output restric-
tion control of a driving support system
operates. (For example: Pre-Collision
System, Drive-Start Control)
●The parking brake is operated.
●The vehicle is stopped by system control
on a steep incline.
●The following are detected when the
vehicle has been stopped by system con-
trol:
• The driver is not wearing a seat belt.
• The driver’s door is opened.
• The vehicle has been stopped for about 3 minutes.
If vehicle-to-vehicle distance control mode
is automatically canceled for any reasons
other than the above, there may be a mal-
function in the system. Contact your Lexus
dealer.
■Automatic cancelation of constant
speed control mode
Constant speed control mode is automati-
cally canceled in the following situations:
●Actual vehicle speed is more than
approximately 10 mph (16 km/h) below
the set vehicle speed.
●Actual vehicle speed falls below approxi-
mately 20 mph (30 km/h).
●VSC is activated.
●TRAC is activated for a period of time.
●When the VSC or TRAC system is
turned off.
●When the brake control or output restric-
tion control of a driving support system
operates. (For example: Pre-Collision
System, Drive-Start Control)
●The parking brake is operated.
If constant speed control mode is automati-
cally canceled for any reasons other than
the above, there may be a malfunction in the
system. Contact your Lexus dealer.

■Vehicles that can be detected by the Blind Spot Monitor
The Blind Spot Monitor uses rear side radar sensors to detect the following vehi-
cles traveling in adjacent lanes and advises the driver of the presence of such vehi-
cles via the indicators on th e outside rear view mirrors.
Vehicles that are traveling in areas that are not visible using the outside rear
view mirrors (the blind spots)
WARNING
●Do not subject a sensor or its sur-
rounding area on the rear bumper to a
strong impact.
If a sensor is moved even slightly off
position, the system may malfunction
and vehicles may not be detected cor-
rectly.
In the following situations, have your
vehicle inspected by your Lexus
dealer.

If a vehicle approaching from the right or
left at the rear of the vehicle is detected,
the RCTA icon (P.279) for the detected
side will be displayed on the Center Dis-
play. This illustration shows an example of a
vehicle approaching from both sides of the
vehicle.
RCTA buzzer
If a vehicle approaching from the right or
left at the rear of the vehicle is detected, a
buzzer will sound. The buzzer also sounds
for approximately 1 second immediately
after the RCTA function is turned on.
Use the meter control switches to
enable/disable the RCTA function.

■Outside rear view mirror indicator visi-
bility
In strong sunlight, the outside rear view mir-
ror indicator may be difficult to see.
■Hearing the RCTA buzzer
The RCTA buzzer may be difficult to hear
over loud noises, such as if the audio system
volume is high.
■When “RCTA Not Available” is shown
on the multi-information display
Water, snow, mud, etc., may be attached to
the rear bumper around the sensors.
( P.267) Removing the water, snow, mud,

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.
NOTICE
■Before using the RCTA function
Do not place obstacles near the sensors.

tery has been disconnected and recon-
nected, fully turn the steering wheel to
the left and then the right on level ground.
●If this message is di splayed only when the
R shift position is selected, the rear cam-
era lens may be dirty. Clean the rear
camera lens.
■Situations in which the system may not
operate properly

sarily, brake control can be canceled by
depressing the brake pedal or waiting for
approximately 2 seconds for it to automati-
cally be canceled. Then, the vehicle can be
operated by depressing the accelerator pedal.
■Re-enabling the Parking Support Brake
To re-enable the Parking Support Brake
when it has been disabled due to operation
of the Parking Support Brake, either enable
the system again ( P.285), or turn the

era lens may be dirty. Clean the camera
lens. If this message is displayed when the
shift position is any position other than R,
a sensor on the front or rear bumper may
be dirty. Clean the sensors and their sur-
rounding area on the bumpers.
●Initialization may not have been per-
formed after a battery terminal was dis-
connected and reconnected. Initialize the
system. ( P.288)
If this message continues to be displayed
even after initializati on, have the vehicle
