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 li mitations 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 ahe ad:
P. 295
• Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly: P. 296
● 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 s olely on this
system 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 s etting to off,
using the cruise control main switch when not in use.

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 se rious 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 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 neces-
sary 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.

WARNING
■Situations unsuitable for dynamic radar cruise control with ful l-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 s harp up
and down gradients
Vehicle speed may exceed the set speed when driving down a stee p 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 rada r or front
camera
● In traffic conditions that require frequent repeated acceleration and decel-
eration
● During emergency towing
● When an approach warning buzzer is heard often

2864-5. Using the driving support systems
When the turn signal lever is operated and your vehicle moves to an over-
taking lane while driving at 50 mph (80 km/h) or more, the vehi cle will
accelerate to help to overtake a passing vehicle.
The system’s identification of what is an overtaking lane may b e deter-
mined solely based on the location of the steering wheel in the vehicle (left
side driver position versus right side driver position.) If the vehicle is driven
to a region where the overtaking lane is on a different side fr om where the
vehicle is normally driven, the vehicle may accelerate when the turn signal
lever is operated in the opposite direction to the overtaking l ane (e.g., if the
driver normally operates the vehicle in a region where the overtaking lane
is to the right but then drives to a region where the overtaking lane is to the
left, the vehicle may accelerate when the right turn signal is activated).
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The syst em then
returns to constant speed cruising.
Press the cruise control main
switch to activate the cruise
control.
Dynamic radar cruise control indi-
cator will come on and a message
will be displayed on the multi-infor-
mation display.
Press the switch again to deacti-
vate the cruise control.
If the cruise control main switch is pressed and held for 1.5 seconds or
more, the system turns on in constant speed control mode. ( P. 292)
Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed (at or
above approximately 20 mph
[30 km/h]) and press the “- SET”
switch to set the speed.
Cruise control “SET” indicator will
come on.
The vehicle speed at the moment
the switch is released becomes the
set speed.

After the vehicle ahead of you
starts off, press the “+ RES”
switch.
Your vehicle will also resume fol-
low-up cruising if the accelerator
pedal is depressed after the vehi-
cle ahead of you starts off.
Pressing the cancel switch can-
cels the speed control.
The speed control is also canceled
when the brake pedal is
depressed.
(When the vehicle has been
stopped by system control,
depressing the brake pedal does
not cancel the setting.)
Pressing the “+ RES” switch resumes the cruise control and returns
vehicle speed to the set speed.

2904-5. Using the driving support systems
When your vehicle is too close to
a vehicle ahead, and sufficient
automatic deceleration via the
cruise control is not possible, the
display will flash and the buzzer
will sound to alert the driver. An
example of this would be if
another driver cuts in front of you
while you are following a vehicle.
Depress the brake pedal to
ensure an appropriate vehicle-to-
vehicle distance.
■Warnings may not occur when
In the following instances, war nings may not occur even when th e
vehicle-to-vehicle distance is small.
● When the speed of the preceding vehicle matches or exceeds
your vehicle speed
● When the preceding vehicle is traveling at an extremely slow
speed
● Immediately after the cruise control speed was set
● When depressing the accelerator pedal
While driving in vehicle-to-vehi cle distance control mode, this function
will reduce the vehicl e speed, if it is determined to be necess ary.
■Function operation
When the steering wheel begins to be turned, the vehicle speed will
begin being reduced. When the steering wheel is returned to the
center position, the vehicl e speed reduction will end.
Depending on the situat ion, the vehicle speed will then return to the
vehicle-to-vehicle distanc e control mode set speed.
In situations where vehicle-to-v ehicle distance control needs to
operate, such as when a preceding vehicle cuts in front of your
vehicle, the curve speed reduction function will be canceled.

2924-5. Using the driving support systems
When constant speed control mode is selected, your vehicle will main-
tain a set speed without controllin g the vehicle-to-vehicle distance.
Select this mode only when vehic le-to-vehicle distance control mode
does not function correctly due to a dirty radar, etc.
With the cruise control off,
press and hold the cruise con-
trol main switch for 1.5 seconds
or more.
Immediately after the switch is
pressed, the dynamic radar cruise
control indicator will come on.
Afterwards, it switches to the cruise
control indicator.
Switching to constant speed control mode is only possible when operating
the switch with the cruise control off.
Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed (at or
above approximately 20 mph
[30 km/h]) and press the “- SET”
switch to se t the speed.
Cruise control “SET” indicator will
come on.

■Dynamic radar cruise control wi th full-speed range can be set when
● The shift lever is in D.
● The desired set speed can be set when the vehicle speed is approximately
20 mph (30 km/h) or more.
(However, when the vehicle speed is set while driving at below approxi-
mately 20 mph [30 km/h], the set speed will be set to approximately 20 mph
[30 km/h].)
■ Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After acceler-
ating, the set speed resumes. However, during vehicle-to-vehicl e distance
control mode, the vehicle speed may decrease below the set spee d 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 fol-
low-up cruising if the vehicle ahead starts off within approxim ately 3 sec-
onds after the switch is pressed.
● If the vehicle ahead starts off within 3 seconds after your vehicle stops, fol-
low-up cruising will be resumed.
■ Automatic cancelation of vehicle-to-vehicle distance control mo de
Vehicle-to-vehicle distance control mode is automatically cance led in the fol-
lowing situations.
● VSC is activated.
● TRAC is activated for a period of time.
● When the VSC or TRAC system is turned off.
● The sensor cannot detect correctly because it is covered in some way.
● When the brake control or output restriction control of a driving support sys-
tem operates. (For example: Pre -Collision System, Drive-Start Control)
● The parking brake is operated.
● The vehicle is stopped by system control on a steep incline.
● The following are detected when the vehicle has been stopped by system
control:
• The driver is not wearing a seat belt.
• The driver’s door is opened.
• The vehicle has been stopped for about 3 minutes
If vehicle-to-vehicle distance control mode is automatically ca nceled for any
reasons other than the above, there may be a malfunction in the system.
