●If the operation conditions (P.176)  
are no longer met while the lane cen- tering function is operating, the buzzer may sound to indicate that the func- 
tion has been temporarily canceled.
■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.
●If the edge of the course* is not clear  
or straight, the lane departure alert  function may not operate.

■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 
If the driver continues to keep their  
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.
●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.
■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.
■Customization 
Function settings can be changed. (Cus- tomizable features:  P.359)
*: If equipped
In vehicle-to-vehicle distance con- 
trol mode, the vehicle automati- 
cally accelerates and decelerates  
to match the speed changes of the  
preceding vehicle even if the accel- 
erator pedal is not depressed. In  
constant speed control mode, the  
vehicle runs at a fixed speed. 
Use the dynamic radar cruise con- 
trol on freeways and highways.

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.186)

2 Accelerate or decelerate, with  
accelerator pedal operation, to  
the desired vehicle speed (at or  
above approximately 30 km/h  
[20 mph]) and press the “-SET”  
switch to set the speed.
Cruise control “SET” indicator will come  on. 
The vehicle speed at the moment the  switch is released becomes the set speed.
■Adjusting the set speed by the

increased or decreased as follows:
Fine adjustment: By 1 km/h (0.6 mph)*1  
or 1 mph (1.6 km/h)*2 each time the  
switch is pressed 
Large adjustment: The speed will con- 
tinue to change while the switch is held.

cle-to-vehicle distance  
increases/decreases in accor- 
dance with vehicle speed. 
1 Pressing the cancel switch can- 
cels the speed control.
The speed control is also canceled  
when the brake pedal is depressed.
2 Pressing the “+RES” switch  
resumes the cruise control and  
returns vehicle speed to the set  
speed.
However, cruise control does not  
resume when the vehicle speed is 
approximately 25 km/h (16 mph) or 
less.
When your vehicle is too close to a  
vehicle ahead, and sufficient auto- 
matic deceleration via the cruise  
control is not possible, the display  
will flash and the buzzer will sound  
to alert the driver. An example of  
this would be if another driver cuts  
in front of you while you are follow- 
ing a vehicle. Depress the brake  
pedal to ensure an appropriate  
vehicle-to-vehicle distance.
■Warnings may not occur when 
In the following instances, warnings  
may not occur even when the vehi-
cle-to-vehicle distance is small.
