PDA (Proactive driv-
ing assist)
When a detectable object
(P.188) is detected, the
proactive driving assist
operates the brakes and
steering wheel to help pre-
vent the vehicle from
approaching too close to
the object.
WARNING
■For safe use
Driving safely is solely the respon-
sibility of the driver.
●The proactive driving assist is
designed to provide some
assistance for regular braking
and steering operations, as well
as helping to prevent the vehicle
from approaching too close to a
detectable object. However, the
scope of this assistance is lim-
ited.
The driver should perform brake
and steering operations as neces-
sary. Read the following items
carefully. Do not overly rely on the
proactive driving assist and
always drive carefully.( P.189)
●The proactive driving assist is
not a system which reduces the
amount of attention necessary
for safe driving. Even if the sys-
tem is operating correctly, the
surrounding conditions as rec-
ognized by the driver and
detected by the system may dif-
fer. It is necessary for the driver
to pay attention, assess risks,
and ensure safety. Over-reli-
ance on this system to drive the
vehicle safely may lead to an
accident resulting in death or
serious injury.
●Proactive driving assist is not a
system which allows for inatten-
tive driving and is not a system
which assists in poor visibility
conditions. The driver is solely
responsible for paying attention
to their surroundings and driving
safely.

Driving
Dynamic radar cruise
control
This dynamic radar cruise
control detects the pres-
ence of vehicles ahead,
determines the current vehi-
cle-to-vehicle distance, and
operates to maintain a suit-
able distance from the vehi-
cle ahead. The desired
vehicle-to-vehicle distance
can be set by operating the
vehicle-to-vehicle distance
switch.
Use the dynamic radar
cruise control only on high-
ways and expressways.
WARNING
■For safe use
●Driving safely is solely the
responsibility of the driver. Do
not overly rely on this system,
and pay careful attention to the
surrounding conditions in order
to ensure safe driving.
●The dynamic radar cruise con-
trol provides driving assistance
to reduce the driver’s burden.
However, there are limitations to
the assistance provided.
Read the following items carefully.
Do not overly rely on this system
and always drive carefully.
Conditions under which the sys-
tem may not operate correctly:
P. 1 9 9
●Set the speed appropriately
according to the speed limit,
traffic flow, road conditions,
weather conditions, etc. The
driver is responsible for confirm-
ing the set speed.
●Even if the system is operating
correctly, the condition of a pre-
ceding vehicle as recognized by
the driver and detected by the
system may differ. Therefore, it
is necessary for the driver to
pay attention, assess risks, and
ensure safety. Over-reliance on
this system to drive the vehicle
safely may lead to an accident
resulting in death or serious
injury.
■Precautions for the driving
assist systems
Observe the following precau-
tions, as there ar e limitations to
the assistance provided by the
system. Over-reliance on this sys-
tem may lead to an accident
resulting in death o r serious injury.
●Details of support provided for
the driver’s vision
The dynamic radar cruise control
is only intended to help the driver
in determining the distance
between the driver’s own vehicle
and a designated preceding vehi-
cle. It is not a system which allows
for careless or inattentive driving,
and is not a system which assists
in poor visibility conditions.
The driver must pay attention to
their surroundings, even when the
vehicle stops.
●Details of suppor t provided for
the driver’s judgement

1944-5. Using the driving support systems
WARNING
The dynamic radar cruise control
determines whether the distance
between the driver’s own vehicle
and a designated preceding vehi-
cle 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.
●Details of support provided for
the driver’s operation
The dynamic radar cruise control
does not include functions which
will prevent or avoid collisions
with vehicles ahead of your vehi-
cle. 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
safety.
■Situations in which the
dynamic radar cruise control
should not be used
Do not use the dynamic radar
cruise control in the following situ-
ations. As the s ystem will not be
able to provide appropriate con-
trol, using it may lead to an acci-
dent resulting in death or serious
injury.
●Roads where there are pedes-
trians, cyclists, etc.
●When driving on a highway or
expressway entrance or exit
●When the approach warning
sounds frequently

pressed while the vehicle is
stopped by system control, if the
preceding vehicle starts off within
approximately 3 seconds, fol-
low-up cruising will resume.
●If the preceding vehicle starts off
within approximately 3 seconds of
the vehicle being stopped by sys-
tem control, follo w-up cruising will
resume.
■Automatic cancellation of vehi-
cle-to-vehicle d istance control
mode
In the following situations, vehi-
cle-to-vehicle dista nce control mode
will be canceled automatically:
●When the brake control or output
restriction control of a driving sup-
port system operates
(For example: Pre-Collision Sys-
tem, drive-start control)
●When the parking brake has been
operated
●When the vehicle is stopped by
system control on a steep incline
●When any of the following are
detected while the vehicle is
stopped by system control:
• The driver’s seat belt is unfas- tened

sor may not detect correctly
In the following situations, depend-
ing on the conditions, if the system
cannot provide sufficient decelera-
tion or acceleration is necessary,
operate the brake pedal or accelera-
tor pedal.
As the sensor may not be able to
correctly detect th ese types of vehi-
cles, the approach warning
(  P.199) may not operate.

your vehicle or changes lanes
away from your vehicle extremely
slowly or quickly
●When changing lanes
●When a preceding vehicle is driv-
ing at a low speed
●When a vehicle is stopped in the
same lane as the vehicle
●When a motorcycle is traveling in
the same lane as the vehicle
■Conditions under which the
system may not operate cor-
rectly
In the following situations, operate
the brake pedal (or accelerator
pedal, depending on the situation)
as necessary.
As the sensor may not be able to
correctly detect a vehicle, the sys-
tem may not operate properly.

and the system cannot provide
sufficient deceleration, such as
if a vehicle cuts in front of the
vehicle, a warning display will
flash and a buzzer will sound to
alert the driver. Depress the
brake pedal to ensure appropri-
ate vehicle-to-vehicle distance.
■Warnings may not occur
when
In the following situations, the
warning may not operate even
though the vehicle-to-vehicle
distance is short.
 When the preceding vehicle is
traveling at the same speed
or faster than your vehicle
 When the preceding vehicle is
traveling at an extremely low
speed
 Immediately after the vehicle
speed has been set
 When the accelerator pedal is
depressed
When a curve is detected, the
vehicle speed will begin being
reduced. When the curve ends,
the vehicle speed reduction will
end.
Depending on the situation, the
vehicle speed will then return to the
set vehicle speed.
In situations where vehicle-to-vehi-
cle distance control needs to oper- ate, such as when a preceding
vehicle cuts in front of your vehicle,
the curve speed reduction function
will be canceled.
■Situations in which the curve
speed reduction function may
not operate
In situations such as the following,
the curve speed reduction function
may not operate:
●When the vehicle is being driven
around a gentle curve
●When the accele rator pedal is
being depressed
●When the vehicle is being driven
around an extremely short curve
If your vehicle is being driven at
approximately 50 mph (80 km/h)
or more and a lane change to
the passing lane is performed,
when the turn signal lever is
operated and the lane is
changed, the vehicle will accel-
erate up to the set speed to
assist in overtaking.
The system’s recognition of which
lane is the passing lane may be
based solely on the location of the
steering wheel in the vehicle
(left-hand drive/right-hand drive). If

the vehicle is driven in a location
where the passing lane is on the
opposite side of that where the
vehicle was originally sold, the
vehicle may accelerate when the
turn signal lever is operated away
from the passing lane. (e.g. The
vehicle was manufactured for a
right-hand traffic location, but is
being driven in a left-hand traffic
location. The vehicle may acceler-
ate when the turn signal lever is
operated to the right.)
If your vehicle is being driven at
approximately 50 mph (80 km/h) or
more and the lane is changed to
that with a vehicle traveling slower
than your vehicle, when the turn
signal lever is operated the vehicle
will gradually decelerate to assist in
changing lanes.
