In the following situations, the RSA sys-
tem will alert the driver.
 When the vehicle speed exceeds
the speed warning threshold of the
speed limit sign displayed, the sign
display will be emphasized and a
buzzer will sound.
 When the RSA system recognizes a
do not enter sign and determines
that your vehicle has entered a no-
entry area, the displayed sign will
flash and a buzzer will sound.
Depending on the situation, traffic
environment (traffic direction, speed
unit) may be detected incorrectly and a
warning display may not operate prop-
erly.

speed limit sign will stop being displayed
automatically:
●A new sign is not recognized for a certain
distance.
●The road changes due to a left or right
turn, etc.
In the following situations, do not enter, stop
and yield signs will stop being displayed
automatically:
●The system determines that your vehicle
has passed the sign.
●The road changes due to a left or right
turn, etc.
■Conditions in which the function may
not operate or detect correctly
In the following situations, RSA does not
operate normally and may not recognize
signs, display the incorrect sign, etc. How-
ever, this does not indicate a malfunction.
●The front camera is misaligned due to a
strong impact being applied to the sen-
sor, etc.
●Dirt, snow, stickers, etc. are on the wind-
shield near the front camera.
●In inclement weather such as heavy rain,
fog, snow or sand storms
●Light from an oncoming vehicle, the sun,
etc. enters the front camera.
●The sign is dirty, faded, tilted or bent.
●All or part of the sign is hidden by the
leaves of a tree, a pole, etc.
●The sign is only visible to the front camera
for a short amount of time.
●The driving scene (turning, lane change,
etc.) is judged incorrectly.
●Even if it is a sign not appropriate for the

currently traveled lane, such a sign exists
directly after a freeway branches, or in an
adjacent lane just before merging.
●Stickers are attached to the rear of the
preceding vehicle.
●A sign resembling a system compatible
sign is recognized.
●Side road speed signs may be detected
and displayed (if positioned in sight of the
front camera) while the vehicle is travel-
ing on the main road.
●Roundabout exit road speed signs may
be detected and displayed (if positioned
in sight of the front camera) while travel-
ing on a roundabout.
●The front of the vehicle is raised or low-
ered due to the carried load.
●The surrounding brightness is not suffi-
cient or changes suddenly.
●When a sign intended for trucks, etc. is
recognized.
●Vehicles with navigation system: The
speed information displayed on the
meter and that displayed on the naviga-
tion system may be different due to the
navigation system using map data.
■Speed limit sign display
If the engine switch wa s last turned off while
a speed limit sign wa s displayed on the
multi-information display, the same sign dis-
plays again when the engine switch is
turned to ON.

Indicators
Dynamic radar cruise con-
trol with full-speed range
In vehicle-to-vehicle distance con-
trol mode, the ve hicle automati-
cally accelerates, decelerates and
stops to match the speed changes
of the preceding vehicle even if the
accelerator pedal is not depressed.
In constant speed control mode,
the vehicle runs at a fixed speed.
Use the dynamic radar cruise con-
trol with full-speed range on free-
ways and highways.

Driving
This mode employs a radar to detect the presence of vehicles up to approximately
328 ft. (100 m) ahead, determines the cu rrent vehicle-to-vehicle following dis-
tance, and operates to maintain a suitab le following distance from the vehicle
ahead. The desired vehicle-to-vehicle distance can also be set by operating the
vehicle-to-vehicle distance switch.
When driving on downhill slopes, the vehicl e-to-vehicle distance may become shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appears
When a vehicle is detected running ahead of you, the system automatically decelerates
your vehicle. When a greater reduction in vehicle speed is necessary, the system applies
the brakes (the stop lights will come on at this time). The sy stem will respond to changes in
the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by
the driver. Approach warning warns you when th e system cannot decelerate sufficiently to
prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehi cle will also stop (vehicle is stopped by sys-
tem control). After the vehicle ahead starts off, pressing the “+RES” switch or depressing
the accelerator pedal (start-off operation) will resume follow-up cruising. If the start-off
operation is not performed, system contro l continues to keep your vehicle stopped.
When the turn signal lever is operated and your vehicle moves to a left lane while driving at
50 mph (80 km/h) or more, the vehicle will quickly accelerate to help to overtake a pass-
ing vehicle.

speed cruising.
1 Press the cruise control main switch
to activate the cruise control.
Dynamic radar cruise control indicator will
come on and a message will be displayed
on the multi-information display. Press the
switch again to deactivate the cruise con-
trol.
If the cruise control ma in switch is pressed
and held for 1.5 seconds or more, the sys-
tem turns on in constant speed control
mode. ( P.211)

■Warnings may not occur when
In the following instances, warnings
may not occur even when the vehicle-
to-vehicle distance is small.
 When the speed of the preceding
vehicle matches or exceeds your
vehicle speed
 When the preceding vehicle is trav-
eling at an extremely slow speed
 Immediately after the cruise control
speed was set
 When depressing the accelerator
pedal
When constant speed control mode is
selected, your vehicle will maintain a
set speed without controlling the vehi-
cle-to-vehicle distance. Select this
mode only when vehicle-to-vehicle dis-
tance control mode does not function
correctly due to a dirty radar, etc.
1 With the cruise control off, press
and hold the cruise control main
switch for 1.5 seconds or more.
Immediately after the switch is pressed, the
dynamic radar cruise control indicator will
come on. Afterwards, it switches to the cruise control indicator.
Switching to constant speed control mode
is only possible when
operating the switch
with the cruise control off.
2 Accelerate or decelerate, with
accelerator pedal operation, to the
desired vehicle speed (at or above
approximately 20 mph [30 km/h])
and press the “-SET” switch to set
the speed.
Cruise control “SET” indicator will come
on.
The vehicle speed at the moment the
switch is released becomes the set speed.

●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
Selecting constant speed con-
trol mode

2124-5. Using the driving support systems
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 vehicle-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.
●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 instructions. ( P.184, 367)
■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.210) may not be activated.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the same
