WARNING
■Situations unsuitable for
dynamic radar cruise control
with full-speed range
Do not use dynamic radar cruise
control with full-speed range in
any of the following situations.
Doing so may result in inappropri-
ate speed control and could
cause an accident resulting in
death or serious injury.
●Roads where there are pedes-
trians, cyclists, etc.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as
those covered with rain, ice or
snow
●On steep downhills, or where
there are sudden changes
between sharp up and down
gradients
Vehicle speed may exceed the
set speed when driving down a
steep hill.
●At entrances to freeways and
highways
●When weather conditions are
bad enough that they may pre-
vent the sensors from detecting
correctly (fog, snow, sand-
storm, heavy rain, etc.)
●When there is rain, snow, etc.
on the front surface of the radar
or front camera
●In traffic conditions that require
frequent repeated acceleration
and deceleration
●When your vehicle is towing a
trailer or during emergency tow-
ing
●When an approach warning
buzzer is heard often

Driving
When the turn signal lever is operated and your vehicle moves to an over-
taking lane while driving at 50 mph (80 km/h) or more, the vehi cle will accel-
erate to help to overt ake a passing vehicle.
The system’s identification of what is an overtaking lane may be determined
solely based on the location of the steering wheel in the vehicle (left side
driver position versus right side driver position.) If the vehi cle is driven to a
region where the overtaking lane is on a different side from wh ere the vehi-
cle is normally driven, the vehicle may accelerate when the tur n signal lever
is operated in the opposite direction to the overtaking lane (e .g., if the driver
normally operates the vehicle in a region where the overtaking lane is to the
right but then drives to a region where the overtaking lane is to the left, the
vehicle may accelerate when the right turn signal is activated).
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The system then
returns to constan t speed cruising.
1Press the cruise control main
switch to activate the cruise
control.
Dynamic radar cruise control indi-
cator will come on and a message
will be displayed on the multi-infor-
mation display. Press the switch
again to deactivate the cruise con-
trol.
If the cruise cont rol main switch is
pressed and held for 1.5 seconds
or more, the syste m turns on in
constant speed control mode. (
 P.265)
2 Accelerate or decelerate,
with accelerator pedal opera-
tion, to the desired vehicle
speed (at or above approxi-
mately 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

1Pressing the cancel switch
cancels the speed control.
The speed control is also canceled
when the brake pedal is depressed.
(When the vehicle has been
stopped by system control,
depressing the brake pedal does
not cancel the setting.)
2Pressing the “+RES” switch
resumes the cruise control
and returns vehicle speed to
the set speed.
When your vehicle is too close
to a vehicle ahead, and suffi-
cient automatic deceleration via
the cruise control is not possi-
ble, the display will flash and the
buzzer will sound to alert the
driver. An example of this would
be if another driver cuts in front
of you while you are following a
vehicle. Depress the brake
pedal to ensure an appropriate
vehicle-to-vehicle distance.
■Warnings may not occur
when
In the following instances, warn-
ings may not occur even when
the vehicle-to-vehicle distance is
small.
 When the speed of the pre-
ceding vehicle matches or
exceeds your vehicle speed
 When the preceding vehicle is
traveling at an extremely slow
speed
 Immediately after the cruise
control speed was set
 When depressing the acceler-
ator pedal
While driving in vehicle-to-vehi-
cle distance control mode, this
function will reduce the vehicle
speed, if it is determined to be
necessary.
■Function operation
When the steering wheel begins
to be turned, the vehicle speed
will begin being reduced. When

Driving
the steering wheel is returned to
the center position, the vehicle
speed reduction will end.
Depending on the situation, the
vehicle speed will then return to
the vehicle-to-vehicle distance
control mode set speed.
In situations where vehi-
cle-to-vehicle distance control
needs to operate, such as when
a preceding vehicle cuts in front
of your vehicle, the curve speed
reduction function will be can-
celed.
■Operation display
Displayed when the vehicle
speed is being reduced.
When the vehicle speed reduc-
tion ends, the display will disap-
pear.
■Changing the settings of
the curve speed reduction
function
The curve speed reduction func-
tion can be enabled/disabled
and the vehicle speed reduction
strength can be adjusted on

When constant speed control
mode is selected, your vehicle
will maintain a set speed without
controlling the vehicle-to-vehi-
cle distance. Select this mode
only when vehicle- to-vehicle dis-
tance control mode does not
function correctly due to a dirty
radar, etc.

■Dynamic radar cruise control
with full-speed range can be set
when
●The shift lever is in D.
●The desired set speed can be set
when the vehicle speed is approx-
imately 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 w
ill be set to
approximately 20 mph [30 km/h].)
■Accelerating after setting the
vehicle speed
The vehicle can a ccelerate by oper-
ating the accelera tor 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 will
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 seconds after your vehicle
stops, follow-up c ruising will be
resumed.
■Automatic cancelation of vehi-
cle-to-vehicle d istance control
mode
Vehicle-to-vehicle distance control
mode is automatically canceled in
the following situations.
●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 cor-
rectly because i t is covered in
some way.
●When the brake control or output
restriction control of a driving sup-
port system operates.

control on a steep incline.
●The following are detected when
the vehicle has been stopped by
system control:
• 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 malfunction in the
system. Contact your Toyota dealer.
■Automatic cancelation of con-
stant speed control mode
Constant speed control mode is
automatically cance led in the follow-
ing situations:
●Actual vehicle speed is more than
approximately 10 mph (16 km/h)
below the set vehicle speed.
●Actual vehicle speed falls below
approximately 20 mph (30 km/h).
●VSC is activated.
●TRAC is activated for a period of
time.

tem, Drive-Start Control)
●Pre-collision braking is activated.
●The parking brake is operated.
If constant speed control mode is
automatically canceled for any rea-
sons other than the above, there
may be a malfunction in the system.
Contact your Toyota dealer.
■Situations in which the curve
speed reduction function may
not operate
In situations such as the following,
the curve speed reduction function
may not operate:
●When the vehicle is being driven
around a gentle curve
●When the accele rator pedal is
being depressed
●When the vehicle is being driven
around an extremely short curve
■Brake operation
A brake operation sound may be
heard and the brake pedal response
may change, but these are not mal-
functions.
■Warning messages and buzzers
for dynamic radar cruise con-
trol with full-speed range
Warning messages and buzzers are
used to indicate a system malfunc-
tion or to inform the driver of the
need for caution while driving. If a
warning message is shown on the
multi-information display, read the
message and follow the instructions.
(  P.233, 467)
■When the sensor may not be
correctly detecting the vehicle
ahead
In the case of the following and
depending on the conditions, oper-
ate the brake pedal when decelera-
tion of the system is insufficient or
operate the accelerator pedal when
acceleration is required.
As the sensor may not be able to
correctly detect th ese types of vehi-
cles, the approach warning
(  P.264) may not be activated.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the
same lane
●Vehicles with small rear ends
(trailers with no load on board,
etc.)
