Driving
WARNING
●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 are limitations to
the assistance provided by the
system. Over-reliance on this sys-
tem may lead to an accident
resulting in death or 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 vehi-
cle and a designated preceding
vehicle. 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 The
dynamic radar cruise control
determines whether the dis-
tance between the driver’s own
vehicle and a designated pre-
ceding vehicle is within a set
range. It is not capable of mak-
ing any other type of judgement.
Therefore, it is absolutely nec-
essary for the driver to remain
vigilant and to determine
whether or not t here is a possi-
bility of danger.
●Details of suppor t provided for
the driver’s operation The
dynamic radar cruise control
does not include functions
which will prevent or avoid colli-
sions with vehicles ahead of
your vehicle. Ther efore, 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 safety.
■Situations in which the
dynamic radar cruise control
should not be used
Do not use the d ynamic radar
cruise control in the following situ-
ations. As the system 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
●Situations in which the sensors
may not operate properly:
 P.263
●Situations in which the lane may
not be detected:  P.264

Constant speed cruising:
When there are no vehicles ahead
The vehicle drives at the speed set by the driver.
If the set vehicle speed is exceeded while driving down a hill, the set vehicle
speed display will blin k and a buzzer will sound.
Deceleration and follow-up cruising
When a preceding vehicle driving slower than the set vehicle
speed is detected
When a vehicle is detected driving ahead of your vehicle, the v ehicle auto-
matically decelerates and if a greater reduction in vehicle spe ed is neces-
sary, the brakes are applied (the stop lights will come on at t his time). The
vehicle is controlled to maintai n the vehicle-to-vehicle distance set by the
driver, in accordance with changes in the speed of the precedin g vehicle. If
vehicle deceleration is not sufficient and the vehicle approaches the vehicle
ahead, the approach wa rning will sound.
Acceleration
When there are no longer any preceding vehicles driving slower
than the set vehicle speed
The vehicle accelerates until th e set vehicle speed is reached and then
resumes constant speed cruising.
Starting off: If a preceding vehi cle stops, the vehicle will also stop
(controlled stop). After the preceding vehicle starts off, pressing
the “RES” switch or depressing the accelerator pedal will resum e
follow-up cruising (start off operation). If a start off operat ion is not
performed, the controlled stop will continue.

Driving
Each time the switch is pressed,
the vehicle-to-vehicle distance
setting will change as follows:
If a preceding vehicle is detected,
the preceding vehicle mark will
be displayed.
The actual vehicle-to-vehicle dis-
tance varies in accordance with the
vehicle speed. Also, when the vehi-
cle is stopped by system control, it
will be stopped at a certain distance
from the preceding vehicle,
depending on the situation, regard-
less of the setting.
■Operating conditions
●D shift position is selected.
●The desired set speed can be set
when the vehicle speed is approx-
imately 20 mph (30 km/h) or more.
(If the vehicle speed is set while
driving at below approximately 20
mph [30 km/h], th e set speed will
be set to approxi mately 20 mph
[30 km/h].)
■Accelerating after setting the
vehicle speed
As with normal driving, acceleration
can be performed by depressing the
accelerator pedal. After accelerat-
ing, the vehicle will return to the set
vehicle speed. However, while in
vehicle-to-vehicle distance control
mode, the vehicle speed may
decrease to below the set vehicle
speed in order to maintain the dis-
tance from the preceding vehicle.
■When the vehicle is stopped by
system control during follow-up
cruising
●When the “RES” switch is pressed
while the vehicle is stopped by
system control, if the preceding
vehicle starts off within approxi-
mately 3 seconds, follow-up cruis-
ing will resume.

■Preceding vehicles that the sen-
sor may not detect correctly
In the following situations, depend-
ing on the conditions, if the system
cannot provide sufficient decelera-
tion or accelerati on is necessary,
operate the brake pedal or accelera-
tor pedal.
As the sensor may not be able to
correctly detect these types of vehi-
cles, the approach warning
(  P.294) may not operate.
●When a vehicle cuts in front of
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 i s 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.
●When a preceding vehicle brakes
suddenly
●When changing lanes at low
speeds, such as in a traffic jam
In situations where the vehicle
approaches a preceding vehicle
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

Driving
 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 whe n a preceding
vehicle cuts in front of your vehicle,
the curve speed r eduction function
will be canceled.
■Situations in which the curve
speed reduction function may
not operate
In situations such as the following,
the curve speed r eduction function
may not operate:
●When the vehicle is being driven
around a gentle curve
●When the accelerator 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-ha nd drive). If the
vehicle is driven in a location where
the passing lane i s 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 traf-
fic location, but is being driven in a
left-hand traffic location. The vehi-
cle may accelera te 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.
