WARNING
●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 mechanism that
allows careless or inattentive driv-
ing, 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 vehi-
cle’s surroundings.
●Assisting the driver to judge
proper following distance
The dynamic radar cruise control
with full-speed range determines
whether the follo wing 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 function s which will pre-
vent or avoid collisions with vehi-
cles ahead of your vehicle.
Therefore, if there is ever any
possibility of da nger, 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
control with full-speed range in
any of the following situations.
Doing so may result in inappropri-
ate speed control and could
cause an accident resulting in
death or serious injury.
●Roads where there are pedes-
trians, 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 d riving down a
steep hill.
●At entrances to freeways and
highways
●When weather conditions are
bad enough that they may pre-
vent the sensors from detecting
correctly (fog, snow, sand-
storm, heavy rain, etc.)
●When there is rain, snow, etc.
on the front surface of the radar
or front camera
●In traffic conditions that require
frequent repeated acceleration
and deceleration
●When your vehicle is towing a
trailer or during emergency tow-
ing
●When an approach warning
buzzer is heard often

the set speed will be set to
approximately 20 mph [30 km/h].)
■Accelerating after setting the
vehicle speed
The vehicle can accelerate by oper-
ating the accelerator pedal. After
accelerating, the set speed
resumes. However, during vehi-
cle-to-vehicle distance control
mode, the vehicle speed may
decrease below the set speed in
order to maintain the distance to the
preceding vehicle.
■When the vehicle stops while
follow-up cruising
●Pressing the “+RES” switch while
the vehicle ahead stops will
resume follow-up cruising if the
vehicle ahead starts off within
approximately 3 seconds after the
switch is pressed.
●If the vehicle ahead starts off
within 3 seconds after your vehicle
stops, follow-up c ruising will be
resumed.
■Automatic cancelation of vehi-
cle-to-vehicle d istance control
mode
Vehicle-to-vehicle distance control
mode is automatically canceled in
the following situations.

BSM (Blind Spot Moni-
tor)*
The Blind Spot Monitor is a
system that uses rear side
radar sensors installed on
the inner side of the rear
bumper on the left and right
side to assist the driver in
confirming safety when
changing lanes.
WARNING
■Cautions regarding the use of
the system
The driver is solely responsible for
safe driving. Always drive safely,
taking care to o bserve your sur-
roundings.
The Blind Spot Monitor is a sup-
plementary function which alerts
the driver that a v ehicle is in a
blind spot of the outside rear view
mirrors or is approaching rapidly
from behind into a blind spot. Do
not overly rely on the Blind Spot
Monitor. As the function cannot
judge if it is safe to change lanes,
over reliance could lead to an
accident resulting in death or seri-
ous injury.
As the system may not function
correctly under certain condi-
tions, the driver’s own visual con-
firmation of safety is necessary.
