■Lane centering function
This function is linked with dynamic
radar cruise control and provides
the required assistance by operat-
ing the steering wheel to keep the
vehicle in its current lane.
When dynamic radar cruise control is
not operating, the lane centering func-
tion does not operate.
In situations where the white (yellow)
lane lines are difficult to see or are not
visible, such as when in a traffic jam,
this function will operate to help follow a
preceding vehicle by monitoring the
position of the preceding vehicle.
■Turning the lane centering
function ON/OFF
Press the LTA switch.
The lane centering function will change
between ON/OFF each time the switch
is pressed.
The current setting will be displayed on
the multi-information display.

4-5. Using the driving support systems
• The dynamic radar cruise control is
operating in vehicle-to-vehicle dis- tance control mode.• Width of traffic lane is approximately 3
to 4 m (10 to 13 ft.). • Turn signal lever is not operated.• Vehicle is not being driven around a
sharp curve. • No system malfunctions are detected. ( P.237)
• Vehicle does not accelerate or decel- erate by a fixed amount or more.• Steering wheel is not operated with a

• Steering assist function is not operat- ing.
■Temporary cancelation of functions
●When operation conditions are no lon-ger met, a function may be temporar-ily canceled. However, when the
operation conditions are met again, operation of the function is automati-cally restored. ( P.235)
●If the operation conditions (P.235) are no longer met while the lane cen-
tering function is operating, the steer- ing wheel may vibrate and the buzzer may sound to indicate that the func-
tion has been temporarily canceled. However, if the steering wheel vibra-tion customization setting is set to on,
the system will notify the driver by vibrating the steering wheel instead of sounding the buzzer.
■Steering assist function/lane cen-
tering function
●Depending on the vehicle speed, lane
departure situation, road conditions, etc., the driver may not feel the func-tion is operating or the function may
not operate at all.
●The steering control of the function is
overridden by the driver’s steering
wheel operation.
●Do not attempt to test the operation of
the steering assist function.
■Lane departure alert function
●The warning buzzer may be difficult to
hear due to external noise, audio play- back, etc. Also, it may be difficult to feel steering wheel vibrations due to
the road conditions, etc.
●If the edge of the course* is not clear
or straight, the lane departure alert function may not operate.
●Vehicle with BSM: It may not be possi-ble for the system to determine if there
is a danger of a collision with a vehicle in an adjacent lane.
●Do not attempt to test the operation of the lane departure alert function.*: Boundary between asphalt and the
side of the road, such as grass, soil,
or a curb
■Hands off steering wheel warning
In the following situations, a warning
message urging the driver to hold the steering wheel and the symbol shown in the illustration are displayed on the
multi-information display to warn the driver. The warning stops when the sys-tem determines that the driver holds the
steering wheel. Always keep your hands on the steering wheel when using this system, regardless of warnings.
●When the system determines that the driver is driving without holding the
steering wheel while the system is operating

hands off of the steering wheel, the
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.
●“LTA Malfunction Visit Your Dealer”
The system may not be operating prop-
erly. Have the vehicle inspected by any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
●“LTA Unavailable”
The system is temporarily canceled due
to a malfunction in a sensor other than
the front camera. Turn the LTA system
off, wait for a little while, and then turn
the LTA system back on.
●“LTA Unavailable at Current Speed”
The function cannot be used as the
vehicle speed exceeds the LTA opera-
tion range. Drive slower.

■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.266), 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.215, 413)
■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.245) 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.)

■If the engine stalls
If the Stop & Start system is enabled and the clutch pedal is depressed quickly, the engine may restart.
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.
