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.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• When the sensor may not be correctly detecting the vehicle ahead:
• Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly:
●
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 sys-
tem or assuming the system ensures safety while driving can lead to an
accident, resulting in death or serious injury.
●
Switch the dynamic radar cruise control with full-speed range off using the
cruise control main switch when not in use.
■
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.
-------------------------------------------------------------------------------------------------------------------------------------------------------------
266
4-5. Using the driving support systems
WARNING
●
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.
■
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 down-
hill 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, pressing the
“+ RES” switch or depressing the accelerator pedal will resume follow-up
cruising.

If the warning message does not disappear, have the vehicle inspected
by your Toyota dealer.
●
Do not subject a sensor or its surrounding area on the rear bumper to a
strong impact.
If a sensor is moved even slightly off position, the system may malfunction
and vehicles may not be detected correctly.
In the following situations, have your vehicle inspected by your Toyota
dealer.
• A sensor or its surrounding area is subject to a strong impact.
• If the surrounding area of a sensor is scratched or dented, or part of
them has become disconnected.
●
Do not disassemble the sensor.
●
Do not attach accessories or stickers to the sensor or surrounding area on
the bumper.
●
Do not modify the sensor or surrounding area on the bumper.
●
Do not paint the rear bumper any color other than an official Toyota color.
●
Keep the sensor and its surrounding
area on the bumper clean at all times.
If a sensor or its surrounding area on
the rear bumper is dirty or covered with
snow, the Blind Spot Monitor may not
operate and a warning message (

The BSM function uses radar sensors to detect vehicles that are trav-
eling in an adjacent lane in the area that is usually not reflected in the
outside rear view mirror (the blind spot), and advises the driver of the
vehicles existence via the outside rear view mirror indicator.
The areas that vehicles can be detected in are outlined below.
The range of the detection area
extends to:
Approximately 11.5 ft. (3.5 m)
from the side of the vehicle
The first 1.6 ft. (0.5 m) from the
side of the vehicle is not in the
detection area
Approximately 9.8 ft. (3 m) from
the rear bumper
Approximately 3.3 ft. (1 m) for-
ward of the rear bumper
■
The BSM function is operational when
●
The BSM function is turned on
●
Vehicle speed is greater than approximately 10 mph (16 km/h).
■
The BSM function will detect a vehicle when
●
A vehicle in an adjacent lane overtakes your vehicle.
●
You overtake a vehicle in adjacent lane slowly.

WARNING
■
Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The BSM function is a supplementary function which alerts the driver that a
vehicle is present in the blind spot. Do not overly rely on the BSM function.
The function cannot judge if it is safe to change lanes, therefore over reli-
ance could cause an accident resulting in death or serious injury.
According to conditions, the system may not function correctly. Therefore
the driver’s own visual confirmation of safety is necessary.

Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The RCTA function is only an assist and is not a replacement for careful
driving. Driver must be careful when backing up, even when using RCTA
function. The driver’s own visual confirmation of behind you and your vehi-
cle is necessary and be sure there are no pedestrians, other vehicles, etc.,
before backing up. Failure to do so could cause death or serious injury.
According to conditions, the system may not function correctly. Therefore
the driver’s own visual confirmation of safety is necessary.

Sensor detection information
●
The sensor’s detection areas are limited to the areas around the vehicle’s
bumper.
●
Depending on the shape of the object and other factors, the detection dis-
tance may shorten, or detection may be impossible.
●
Objects may not be detected if they are too close to the sensor.
●
There will be a short delay between object detection and display. Even at
slow speeds, there is a possibility that the object will come within the sen-
sor’s detection areas before the display is shown and the buzzer sounds.
●
Thin posts or objects lower than the sensor may not be detected when
approached, even if they have been detected once.
●
It might be difficult to hear beeps due to the volume of audio system or air
flow noise of the air conditioning system.
■

If “Parking Assist Unavailable Please Clean Parking Assist Sensor” is
displayed on the multi-information display
A sensor may be dirty or covered with snow or ice. In such cases, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a malfunction dis-
play may appear or an object may not be detected. If the sensor thaws out,
the system should return to normal.

Sensors
Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an object. Particular instances where
this may occur are listed below.
●
There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve
this problem.)
●
The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show an
abnormal display, or objects may not be detected.
●
The sensor is covered in any way.
●
The vehicle is leaning considerably to one side.
●
On an extremely bumpy road, on an incline, on gravel, or on grass.
●
The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicles, or other loud noises producing ultra-
sonic waves.
●
There is another vehicle equipped with parking assist sensors in the vicin-
ity.
●
The sensor is coated with a sheet of spray or heavy rain.
●
The sensor is drenched with water on a flooded road.
●
The vehicle is equipped with a fender pole or wireless antenna.
●
Towing eyelets are installed.
●
The bumper or sensor receives a strong impact.
●
The vehicle is approaching a tall or curved curb.
●
The detection range is reduced due to an object such as a sign.
●
In harsh sunlight or intense cold weather.
●
The area directly under the bumpers is not detected.
●
If objects draw too close to the sensor.
●
A non-genuine Toyota suspension (lowered suspension, etc.) is installed.
●
A backlit license plate is installed.
In addition to the examples above, there are instances in which, because of
their shape, signs and other objects may be judged by a sensor to be closer
than they are.

NOTICE
■
When using intuitive parking assist
In the following situations, the system may not function correctly due to a
sensor malfunction, etc. Have the vehicle checked by your Toyota dealer.
●
The intuitive parking assist operation display flashes, and a buzzer sounds
when no objects are detected.
●
If the area around a sensor collides with something, or is subjected to
strong impact.
●
If the bumper collides with something.
●
If the display shows continuously without beeping, except when the buzzer
volume is muted.
●
If a display error occurs, first check the sensor.
If the error occurs even if there is no ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.
