Driving 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.
●
Pre-collision braking is activated.
●
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. ●
Pre-collision braking is activated.
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. ■
Brake operation
A brake operation sound may be heard and
the brake pedal response may change, but
these are not malfunctions. ■
Warning messages and buzzers for
dynamic radar 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 driv-
ing. If a warning messa ge is shown on the
multi-information displa y, read the message
and follow the instruc-
tions.(  P.196,202,425)
■
When the sensor may not be correctly
detecting the vehicle ahead
In the case of the fo llowing and depending
on the conditions, operate the brake pedal
when deceleration of the system is insuffi-
cient or operate the accelerator pedal
when acceleration is required.
As the sensor may not be able to correctly
detect these types of vehicles, the approach
warning (  P.243) may not be activated.

■
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 ve hicle and alerts the driver of the presence
of such vehicles by flashing the outside rear view mirror indi cators and sounding a
buzzer.Turning the RCTA function

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.

Driving with the RCTA function on
• When the sensors cannot detect a vehi-
cle due to obstructions
●
Instances of the RCTA function unneces-
sarily detecting a vehicle and/or object
may increase in the following situations:
• When a vehicle passes by the side of your
vehicle
• When the parking space faces a street
and vehicles are being driven on the
street
• When the distance between your vehicle
and metal objects, such as a guardrail,
wall, sign, or parked vehicle, which may
reflect electrical waves toward the rear of
the vehicle, is short
• When a towing eyelet is installed to the
rear of the vehicle *

(  P.286)PKSB (Parking Support
Brake) *
The Parking Support Brake system
consists of the following functions
that operate when driving at a low
speed or backing up, such as when
parking. When the system deter-
mines that a collision with a
detected object or pedestrian is
high, a warning operates to urge
the driver to take evasive action. If
the system determines that the pos-
sibility of a collision with a detected
object or pedestrian is extremely
high, the brakes are automatically
applied to help avoid the collision or
help reduce the impact of the colli-
sion.

system WARNING■
Limitations of the Parking Support
Brake system
Do not overly rely on the system, as
doing so may lead to an accident. ●
The driver is solely responsible for safe
driving. Always drive carefully, taking
care to observe your surroundings.
The Parking Support Brake system is
designed to provide support to lessen
the severity of collisions. However, it
may not operate in some situations. ●
The Parking Support Brake system is
not designed to stop the vehicle com-
pletely. Additionally, even if the system
has stopped the vehicl e, it is necessary
to depress the brake pedal immedi-
ately as brake control will be canceled
after approximately 2 seconds.
NOTICE■
If “Parking Support Brake Unavail-
able” is displayed on the multi-infor-
mation display and the PKSB OFF
indicator is flashing
If this message is displayed immediately
after the engine swit ch is changed to
IGNITION ON mode, operate the vehi-
cle carefully, paying attention to your sur-
roundings. It may be necessary to drive
the vehicle for a certain amount of time
before the system returns to normal. (If
the system is not return to normal after
driving for a while, clean the rear camera
lens.)

Parking precaution
If the vehicle is parked for a long time, the
vehicle height may change due to
changes in the ambient temperature.
When parking the vehicle, make sure
that the area above and below the vehi-
cle is clear, so that the vehicle will not
contact anything if its height changes.
Be careful when parking the vehicle in an
area with a low ceiling or near low hang-
ing objects, as the vehicle height will
