Warning message
If the following warning message is displayed on the multi-information display
and the LDA indicator illuminates in amber, follow the appropriate trouble-
shooting procedure.
If a different warning message is displayed, follow the instructions displayed
on the screen.
Warning messageDetails/Actions
“Check LDA System”
The system may not be operating
properly.
Have the vehicle inspected at your
Toyota dealer.
“Forward Camera
System
Unavailable
Clean Windshield”
Dirt, rain, condensation, ice, snow,
etc., are present on the windshield in
front of the camera sensor.
Turn the LDA system off, remove
any dirt, rain, condensation, ice,
snow, etc., from the windshield, and
then turn the LDA system back on.
“Forward Camera
System
Unavailable”
The LDA system is temporarily can-
celed because the operating condi-
tions of the camera sensor
(temperature, et c.) are not met.
The LDA system can be operated
when the operating conditions of
the camera sensor (temperature,
etc.) are met. Turn the LDA system
off, wait for a while, and then turn
the LDA system back on.
“LDA Not Available”
The LDA system is temporarily can-
celed due to a malfunction in a sensor
other than the camera sensor.
Turn the LDA system off and follow
the appropriate troubleshooting
procedures for other warning mes-
sages. Afterward, drive the vehicle
for a short time, and then turn the
LDA system back on.
“LDA Unavailable Below
Approx. 32 MPH”
The LDA system cannot be used as
the vehicle speed is approximately 32
mph (50 km/h) or less.
Drive the vehicle at approximately
32 mph (50 km/h) or more.

This mode employs a radar sensor to detect the presence of vehicles
up to approximately 400 ft. (120 m) ahead, determines the current
vehicle-to-vehicle following distance, and operates to maintain a suit-
able following distance from the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on long
downhill slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle distance can also be set by operating the vehicle-to-vehicle dis-
tance button.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
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 system then
returns to constant speed cruising.

Press the “ON-OFF” button to
activate the cruise control.
Radar cruise control indicator will
come on and a message will be
displayed on the multi-information
display.
Press the button again to deacti-
vate the cruise control.
If the “ON-OFF” button is pressed
and held for 1.5 seconds or more,
the system turns on in constant
speed control mode. ( P. 228)
Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed
(above approximately 30 mph
[50 km/h]) and push the lever
down to set the speed.
Cruise control “SET” indicator will
come on.
The vehicle speed at the moment
the lever is released becomes the
set speed.

If a vehicle is running ahead of you, the preceding vehicle mark will also be
displayed.
Select a distance from the table below. Note that the distances shown
correspond to a vehicle speed of 50 mph (80 km/h). Vehicle-to-vehicle
distance increases/decreases in accordance with vehicle speed.

Pulling the lever toward you
cancels the speed control.
The speed control is also canceled
when the brake pedal is
depressed.
Pushing the lever up 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 mph (40 km/h) or
less.
When your vehicle is too close to
a vehicle ahead, and sufficient
automatic 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 following 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
vehicle-to-vehicle distance is small.
●When the speed of the preceding vehicle matches or exceeds
your vehicle speed
● When the preceding vehicle is traveling at an extremely slow
speed
● Immediately after the crui se control speed was set
● When depressing the accelerator pedal

When constant speed cont rol mode is selected, your vehicle will main-
tain a set speed without controlling the vehicle-to-vehicle distance.
Select this mode only when vehicl e-to-vehicle distance control mode
does not function co rrectly due to a dirty radar sensor, etc.
With the cruise control off,
press and hold the “ON-OFF”
button for 1.5 seconds or more.
Immediately after the “ON-OFF”
button is pressed, the radar cruise
control indicator will come on.
Afterwards, it switches to the cruise
control indicator.
Switching to constant speed con-
trol mode is only possible when
operating the lever with the cruise
control off.
Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed
(above approximately 30 mph
[50 km/h]) and push the lever
down to set the speed.
Cruise control “SET” indicator will
come on.
The vehicle speed at the moment
the lever is released becomes the
set speed.

■Dynamic radar cruise control can be set when
●The shift lever is in D or range 4 or higher of S has been selected.
● Range 4 or higher of D has been selected by using the paddle shift switch.
(vehicles with paddle shift switches)
● Vehicle speed is above approximately 30 mph (50 km/h).
■ Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After acceler-
ating, the set speed resumes. However, during vehicle-to-vehicle distance
control mode, the vehicle speed may decrease below the set speed in order
to maintain the distance to the preceding vehicle.
■ Automatic cancelation of vehicle -to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the fol-
lowing situations.
● Actual vehicle speed falls below approximately 25 mph (40 km/h).
● VSC is activated.
● TRAC is activated for a period of time.
● When the VSC or TRAC system is turned off by pressing the VSC OFF
switch.
● The sensor cannot detect correctly because it is covered in some way.
● Pre-collision braking is activated.
If vehicle-to-vehicle distance control mode is automatically canceled for any
other reason, there may be a malfunction in the system. Contact your Toyota
dealer.
