• 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 force level suitable for chang- ing lanes.• ABS, VSC, TRC and PCS are not
operating. • TRC or VSC is not turned off.• Hands off steering wheel warning is
not displayed. ( P.236) • The vehicle is being driven in the center of a lane.
• 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.

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.

WARNING
■Before using dynamic radar cruise control with full-speed range
●Driving safely is the sole responsi-bility of the driver. Do not rely solely on the system, and drive safely by
always paying careful attention to your surroundings.
●The dynamic radar cruise control with full-speed range provides driv-ing assistance to reduce the
driver’s burden. However, there are limitations to the assistance pro-vided.
Read the following conditions care-
fully. Do not overly rely on this system
and always drive carefully.
• When the sensor may not be cor-
rectly detecting the vehicle ahead: P.248

4-5. Using the driving support systems
When the turn signal lever is operated and your vehicle moves t o an overtaking lane
while driving at 80 km/h (50 mph) or more, the vehicle will acc elerate to help to over-
take a passing vehicle.
The system’s identification of what is an overtaking lane may b e determined solely
based on the location of the steering wheel in the vehicle (lef t side driver position
versus right side driver position.) If the vehicle is driven to a region where the over-
taking lane is on a different side from where the vehicle is no rmally driven, the vehi-
cle may accelerate when the turn signal lever is operated in th e 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 over-
taking lane is to the left, the vehicle may accelerate when the right turn signal is acti-
vated).
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 syst em then returns to
constant speed cruising.
1 Press the cruise control main
switch to activate the cruise con-
trol.
Dynamic radar cruise control indicator will come on and a message will be dis-played on the multi-information display.
Press the switch again to deactivate the cruise control.
If the cruise control main switch is
pressed and held for 1.5 seconds or more, the system turns on in constant
speed control mode. ( P.245)
