Dynamic Radar Cruise Control with
Road Sign Assist can be
enabled/disabled in the screen
on the multi-information display.
(P.186)
■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 approxi-
mately 30 km/h (20 mph) or more.
(However, when the vehicle speed is
set while driving at below approxi-
mately 30 km/h [20 mph], the set
speed will be set to approximately 30
km/h [20 mph].)
■Accelerating after setting the vehi-
cle speed
The vehicle can accelerate by operating
the accelerator pedal. After accelerat-
ing, the set speed resumes. However,
during vehicle-to-vehicle distance con-
trol mode, the vehicle speed may
decrease below the set speed in order
to maintain the distance to the preced-ing vehicle.
■When the vehicle stops while fol-
low-up cruising
●Pressing the “+RES” switch while the
vehicle ahead stops will resume fol-
low-up cruising if the vehicle ahead
starts off within approximately 3 sec-
onds after the switch is pressed.
●If the vehicle ahead starts off within 3
seconds after your vehicle stops, fol-
low-up cruising will be resumed.
■Automatic cancelation of vehicle-
to-vehicle distance control mode
Vehicle-to-vehicle distance control
mode is automatically canceled in the
following situations.
●VSC is activated.
●TRC is activated for a period of time.
●When the VSC or TRC 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 con-
trol 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 any authorized Toyota retailer
or Toyota authorized repairer, or any
reliable repairer.
■Automatic cancelation of constant
speed control mode
Constant speed control mode is auto-
matically canceled in the following situa-
tions:
Enabling/Disabling the
Dynamic Radar Cruise Con-
trol with Road Sign Assist
(vehicles with RSA)
Page 386 of 664

3865-5. Using the driving support systems
●Actual vehicle speed is more than
approximately 16 km/h (10 mph) below the set vehicle speed.
●Actual vehicle speed falls below approximately 30 km/h (20 mph).
●VSC is activated.
●TRC is activated for a period of time.
●When the VSC or TRC system is turned off.
●Pre-collision braking is activated.
●The parking brake is operated.
If constant speed control mode is auto-
matically canceled for any reasons other
than the above, there may be a malfunc-
tion in the system. Contact any autho-
rized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
■The Dynamic Radar Cruise Control with Road Sign Assist may not
operate properly when (vehicles with RSA)
As the Dynamic Radar Cruise Control
with Road Sign Assist may not operate properly in conditions in which RSA may not operate or detect correctly
( P.375), when using this function, make sure to check the speed limit sign displayed.
In the following situations, the set speed may not be changed to the recognized speed limit by pressing and holding the
“+RES”/“-SET” switch.
●If speed limit information is not avail-
able
●When the recognized speed limit is
the same as the set speed
●When the recognized speed limit is
outside of the speed range that the dynamic radar cruise control system can operate
■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 cau-tion while driving. If a warning message
is shown on the multi-information dis- play, read the message and follow the instructions. ( P.353, 578)
■When the sensor may not be cor-
rectly detecting the vehicle ahead
In the case of the following and depend- ing on the conditions, operate the brake
pedal when deceleration of the system is insufficient or operate the accelerator pedal when acceleration is required.
As the sensor may not be able to cor- rectly detect these types of vehicles, the approach warning ( P.383) 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.)
●Motorcycles traveling in the same lane
●When water or snow thrown up by the
surrounding vehicles hinders the detecting of the sensor
●When your vehicle is pointing upwards (caused by a heavy load in the luggage compartment, etc.)

●Preceding vehicle has an extremely
high ground clearance
■Conditions under which the vehi-
cle-to-vehicle distance control
mode may not function correctly
In the case of the following conditions,
operate the brake pedal (or accelerator
pedal, depending on the situation) as
necessary.
As the sensor may not be able to cor-
rectly detect vehicles ahead, the system
may not operate properly.
●When the road curves or when the
lanes are narrow
●When steering wheel operation or
your position in the lane is unstable
●When the vehicle ahead of you decel-
erates suddenly
●When driving on a road surrounded by
a structure, such as in a tunnel or on a
bridge
●While the vehicle speed is decreasing
to the set speed after the vehicle
accelerates by depressing the accel-
erator pedal

■Accelerating after setting the vehi-
cle speed
●The vehicle can be accelerated nor-
mally. After acceleration, the set speed resumes.
●Even without canceling the cruise control, the set speed can be increased by first accelerating the
vehicle to the desired speed and then pushing the “-SET” switch to set the
new speed.
■Automatic cancelation of cruise control
Cruise control will stop maintaining the
vehicle speed in any of the following sit-
uations.
●Actual vehicle speed falls more than approximately 16 km/h (10 mph)
below the preset vehicle speed.
●Actual vehicle speed is below approxi-
mately 30 km/h (20 mph).
●VSC is activated.
●TRC is activated for a period of time.
●When the VSC or TRC system is turned off.
■If the warning message for the cruise control is shown on the
multi-information display
Press the cruise control main switch once to deactivate the system, and then
press the switch again to reactivate the system.If the cruise control speed cannot be set
or if the cruise control cancels immedi- ately after being activated, there may be a malfunction in the cruise control sys-
tem. Have the vehicle inspected by any authorized Toyota retailer or Toyota authorized repairer, or any reliable
