Temporary cancellation of functions
When the operation conditions are no longer met, a function may be tempo-
rarily canceled. However, when the operation conditions are met again, oper-
ation of the function is automatically restored. (
■
Steering control function
Depending on the vehicle speed, lane departure situation, road conditions,
etc., the driver may not feel the function is operating or the function may not
operate at all.
■
Lane departure alert function
The warning buzzer may be difficult to hear due to external noise, audio play-
back, etc.
■
Hands off steering wheel alert
If the driver continues to keep their hands off of the steering wheel, a warning
message and the symbol shown in the illustration are displayed on the multi-
information display, and the function is temporarily canceled. This warning
also operates in the same way when the driver continuously operates the
steering wheel only a small amount. Always keep your hands on the steering

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
the warning message. Afterward, drive the
vehicle 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

Dynamic radar cruise controlwith full-speed
range
In vehicle-to-vehicle distance control mode, the vehicle automatically
accelerates, decelerates and stops to match the speed changes of the
preceding vehicle even if the accelerator pedal is not depressed. In
constant speed control mode, the 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 with full-speed range provides driving
assistance to reduce the driver’s burden. However, there are limitations to
the assistance provided.
Set the speed appropriately depending on the speed limit, traffic flow, road
conditions, weather conditions, etc. The driver is responsible for checking
the set speed.
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, the 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 within 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 radar 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
●
During emergency towing
●
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.
Driving in vehicle-to-vehicle distance control mode
252
4-5. Using the driving support systems
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.

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. (
Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed (at or
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 the lever is operated while the
vehicle speed is below approxi-
mately 30 mph (50 km/h) and a
preceding vehicle is present, the
set speed will be adjusted to
approximately 30 mph (50 km/h).
