buzzer sounds, the driver is warned and
the function is temporarily canceled.
This warning also operates in the same
way when the driver continuously oper-
ates the steering wheel only a small
amount.
The buzzer also sounds even if the alert
type is set to steering wheel vibration.
●When the system determines that the vehicle may deviate from the lane while driving around a curve while the
lane centering function is operating.
Depending on the vehicle condition and
road conditions, the warning may not
operate. Also, if the system determines
that the vehicle is driving around a
curve, warnings will occur earlier than
during straight-lane driving.
●When the system determines that the
driver is driving without holding the steering wheel while the steering wheel assist of the steering assist
function is operating.
If the driver continues to keep their
hands off of the steering wheel and the
steering wheel assist is operating, the
buzzer sounds and the driver is warned.
Each time the buzzer sounds, the con-
tinuing time of the buzzer becomes lon-
ger.
The buzzer also sounds even if the alert
type is set to steering wheel vibration.
■Vehicle sway warning function
When the system determines that the vehicle is swaying while the vehicle
sway warning function is operating, a buzzer sounds and a warning message urging the driver to rest and the symbol
shown in the illustration are simultane- ously displayed on the multi-information display.
Depending on the vehicle and road con-
ditions, the warning may not operate.
■Warning message
If the following warning message is dis- played on the multi-information display
and the LTA indicator illuminates in orange, follow the appropriate trouble-shooting procedure. Also, if a different
warning message is displayed, follow the instructions displayed on the screen.

Road Sign Assist can be
enabled/disabled in on the
multi-information display. ( P.498)
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 displayed set vehi-
cle 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.
●When snow mode is set.
●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

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.269), 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.229, 449)
■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.259) may not be activated.

BSM (Blind Spot Moni-
tor)*
The Blind Spot Monitor is a
system that uses rear side
radar sensors installed on the
inner side of the rear bumper
on the left and right side to
assist the driver in confirming
safety when changing lanes.
WARNING
■Cautions regarding the use of
the system
The driver is solely responsible for safe driving. Always drive safely, tak-
ing care to observe your surround- ings.
The Blind Spot Monitor is a supple-
mentary function which alerts the driver that a vehicle is in a blind spot of the outside rear view mirrors or is
approaching rapidly from behind into a blind spot. Do not overly rely on the
Blind Spot Monitor. As the function cannot judge if it is safe to change lanes, over reliance could lead to an
accident resulting in death or serious injury.
As the system may not function cor-
rectly under certain conditions, the driver’s own visual confirmation of safety is necessary.
