WARNING
■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 fol-
lowing distance
The dynamic radar cruise control with
full-speed range is only intended to
help the driver in determining the fol-
lowing distance between the driver’s
own vehicle and a designated vehicle
traveling ahead. It is not a mechanism
that allows careless or inattentive
driving, and it is not a system that can
assist the driver in low-visibility condi-
tions.
It is still necessary for driver to pay
close attention to the vehicle’s sur-
roundings.
●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 necessary 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 does not include
functions which will prevent or avoid
collisions with vehicles ahead of your
vehicle. Therefore, if there is ever any
possibility of danger, the driver must
take immediate and direct control 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 con- trol with full-speed range in any of the
following situations. Doing so may result in inappropriate speed control and could cause an accident 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 high- ways
●When weather conditions are bad enough that they may prevent the sensors from detecting correctly
(fog, snow, sandstorm, heavy rain, etc.)

Driving
■If “Parking Assist Unavailable” is
displayed on the multi-information
display (vehicles with PKSB)
Water may be continuously flowing over
the sensor surface, such as in a heavy
rain. When the system determines that it
is normal, the system will return to nor-
mal.
■Sensor detection information
●The sensor’s detection areas are lim-
ited to the areas around the vehicle’s
front and rear bumpers.
●The following situations may occur
during use.
• Depending on the shape of the object
and other factors, the detection dis-
tance may shorten, or detection may
be impossible.
• Detection may be impossible if static
objects draw too close to the sensor.
• There will be a short delay between
static object detection and display
(warning buzzer sounds). Even at low
speeds, there is a possibility that the
object will come within 25 cm (9.8 in.)
before the display is shown and the
warning buzzer sounds.
• It might be difficult to hear the buzzer
due to the volume of the audio system
or air flow noise of the air conditioning
system.
• It may be difficult to hear the sound of
this system due to the buzzers of
other systems.
■Conditions under which the func-
tion may not function correctly
Certain vehicle conditions and the sur-
rounding environment may affect the
ability of a sensor to correctly detect
objects. Particular instances where this
may occur are listed below.
●There is dirt, snow or ice on a sensor.
(Cleaning the sensors will resolve this
problem.)
●A sensor is frozen. (Thawing the area
will resolve this problem.)
In especially cold weather, if a sensor
is frozen the sensor display may be
displayed abnormally, or objects, such
as a wall, may not be detected.
●A sensor is covered in any way.
●When a sensor or the area around a
sensor is extremely hot or cold.
●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 ultrasonic
waves.
●There is another vehicle equipped
with parking assist sensors in the
vicinity.
●A sensor is coated with a sheet of
spray or heavy rain.
●If a sensor is hit by a large amount of
water, such as when driving on a
flooded road.
●If the vehicle is significantly tilted.
●The vehicle is approaching a tall or
curved curb.
●If objects draw too close to the sensor.
■Objects which may not be properly
detected
The shape of the object may prevent the
sensor from detecting it. Pay particular
attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that
absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections pro-
jecting outwards in the direction of
your vehicle
