Warning message
If the following warning message is displayed on the multi-information dis-
play, follow the appropriate troubleshooting procedure.
If a different warning message is displayed, follow the instructions displayed
on the screen.
Warning messageDetails/Actions
“Lane Departure
Alert
Malfunction.
Visit Your Dealer.”The system may not be operating properly.
→ Have the vehicle inspected at your Toyota
dealer.
“Front Camera
Vision Blocked.
Clean and Demist 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.
“Front Camera System
Unavailable.”
The operation conditions of the camera sensor
(temperature, etc.) are not met.
→ When the operation conditions of the camera
sensor (temperature, etc.) are met, the LDA
system will become available. Turn the LDA
system off, wait for a little while, and then
turn the LDA system back on.
“LDA Unavailable.”
The LDA system is temporarily canceled due to
a malfunction in a sensor other than the camera
sensor.
→ Turn the LDA system off and follow the
appropriate troubleshooting procedures for
warning messages. Afterward, drive the vehi-
cle for a short time, and then turn the LDA
system back on.
“LDA Unavailable
Below Approx. 32 MPH(50km/h).”
The LDA system cannot be used as the vehicle
speed is approximately less than 32 mph (50
km/h).
→ Drive the vehicle at approximately 32 mph (50
km/h) or more.

Dynamic radar cruise control with full-speed
range
In vehicle-to-vehicle distance co ntrol mode, the vehicle automatically
accelerates, decelerates and stops to match the speed changes of the
preceding vehicle even if the acce lerator pedal is not depressed. In
constant speed control mode, t he vehicle runs at a fixed speed.
Use the dynamic radar cruise control with full-speed range on free-
ways and highways.

WARNING
■Before using dynamic radar cruise control with full-speed range
Driving safely is the sole responsibility of the driver. Do not rely solely on the
system, and drive safely by always paying careful attention to your sur-
roundings.
The dynamic radar cruise control wi th full-speed range provides driving
assistance to reduce the driver’s burden. However, there are limitations to
the assistance provided.
Even when the system is functioning normally, the condition of the preced-
ing vehicle as detected by the system may differ from the condition
observed by the driver. Therefore, th e driver must always remain alert,
assess the danger of each situation and drive safely. Relying on this system
or assuming the system ensures safety while driving can lead to an acci-
dent, resulting in death or serious injury.
■ Cautions regarding the driving assist systems
Observe the following precautions, as there are limitations to the assistance
provided by the system.
Failure to do so may cause an accident resulting in death or serious injury.
● Assisting the driver to measure following distance
The dynamic radar cruise control with full-speed range is only intended to
help the driver in determining the following distance between the driver’s
own vehicle and a designated vehicle traveling ahead. It is not a mecha-
nism that allows careless or inattentive driving, and it is not a system that
can assist the driver in low-visibility conditions. It is still necessary for
driver to pay close attention to the vehicle’s surroundings.
● Assisting the driver to judge proper following distance
The dynamic radar cruise control with full-speed range determines
whether the following distance between the driver’s own vehicle and a
designated vehicle traveling ahead is with in a set range. It is not capable
of making any other type of judgement. Therefore, it is absolutely neces-
sary for the driver to remain vigilant and to determine whether or not there
is a possibility of danger in any given situation.
● Assisting the driver to operate the vehicle
The dynamic radar cruise control with full-speed range has limited capabil-
ity to prevent or avoid a collision with a vehicle traveling ahead. Therefore,
if there is ever any danger, the driver must take immediate and direct con-
trol of the vehicle and act appropriately in order to ensure the safety of all
involved.

WARNING
■To avoid inadvertent dynamic rada r cruise control with full-speed
range activation
Switch the dynamic radar cruise control with full-speed range off using the
“ON-OFF” button when not in use.
■ Situations unsuitable for dynamic radar cruise control with full-speed
range
Do not use dynamic radar cruise control with full-speed range in any of the
following situations.
Doing so may result in inappropriate speed control and could cause an acci-
dent resulting in death or serious injury.
● Roads where there are pedestrians, cyclists, etc.
● In heavy traffic
● On roads with sharp bends
● On winding roads
● On slippery roads, such as those covered with rain, ice or snow
● On steep downhills, or where there are sudden changes between sharp up
and down gradients
Vehicle speed may exceed the set speed when driving down a steep hill.
● At entrances to freeways and highways
● When weather conditions are bad enough that they may prevent the sen-
sors from detecting correctly (fog, snow, sandstorm, heavy rain, etc.)
● When there is rain, snow, etc., on the front surface of the radar sensor or
camera sensor
● In traffic conditions that require frequent repeated acceleration and decel-
eration
● When an approach warning buzzer is heard often

This mode employs a radar sensor to detect the presence of vehicles
up to approximately 328 ft. (100 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 switch.
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.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pushing the
cruise control lever up or depressing the accelerator pedal will resume fol-
low-up cruising.
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.
