*: If equipped
The system can detect the follow-
ing (The detectable objects differs
depending on the function.):
 Vehicles
 Bicyclists
 Pedestrians
■Pre-collision warning
When the system determines that
the possibility of a frontal collision is
high, a buzzer will sound and a
warning message will be displayed
on the multi-information display to
urge the driver to take evasive
action.
■Pre-collision brake assist
When the system determines that
the possibility of a frontal collision is
high, the system applies greater
braking force in relation to how
strongly the brake pedal is
depressed.
■Pre-collision braking
If the system determines that the
possibility of a frontal collision is
extremely high, the brakes are
automatically applied to help avoid
the collision or reduce the impact of
the collision.
■Emergency steering assist
If the system determines that the
possibility of a collision with a
pedestrian is high and that there is
sufficient space for the vehicle to be
PCS (Pre-Collision Sys-
tem)*
The pre-collision system uses
a radar sensor and front cam-
era to detect objects ( P.209)
in front of the vehicle. When
the system determines that the
possibility of a frontal collision
with an object is high, a warn-
ing operates to urge the driver
to take evasive action and the
potential brake pressure is
increased to he lp the driver
avoid the collision. If the sys-
tem determines that the possi-
bility of a frontal collision with
an object is extremely high, the
brakes are automatically
applied to help avoid the colli-
sion or help reduce the impact
of the collision.
The pre-collision system can be
disabled/enabled and the warn-
ing timing can be changed.

Dynamic Radar Cruise Control with
Road Sign Assist can be
enabled/disabled in on the
multi-information display. ( P.431)
When the Dynamic Radar Cruise
Control with Road Sign Assist is
operating, while driving down a hill,
the vehicle speed may exceed the
set speed.In this case, the dis-
played set vehicle speed will be
highlighted and a buzzer will sound
to alert the driver.
■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 preceding
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 follow-ing 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.
●When the brake control or output
restriction 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 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 reli- able repairer.

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 (if equipped)
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.247), 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.207, 383)
■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.237) 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.)
