Driving
In vehicle-to-vehicle distance control mode, the vehicle automatically
accelerates, decelerates and stops to match the speed changes of the
preceding vehicle even if the accelerator pedal is not depressed. In
constant speed control mode, the vehicle runs at a fixed speed.
Use the dynamic radar cruise control with full-speed range on free-
ways and highways.

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 limitations 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 ahead:
P. 274
• Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly: P. 275
●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 on this sys-
tem 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 off using the
cruise control main switch when not in use.
■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 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 surroundings.
●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.

WARNING
●Assisting the driver to operate the vehicle
The dynamic radar cruise control with full-speed range has limited capabil-
ity to prevent or avoid a collision with a vehicle traveling ahead. Therefore,
if there is ever any danger, the driver must take immediate and direct con-
trol 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 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 sharp up
and down gradients
Vehicle speed may exceed the set speed when driving down a steep 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 radar sensor or
camera sensor
●In traffic conditions that require frequent repeated acceleration and decel-
eration
●When an approach warning buzzer is heard often

2664-5. Using the driving support systems
This mode employs a radar sensor to detect the presence of vehicles
up to approximately 328 ft. (100 m) ahead, determines the current
vehicle-to-vehicle following distance, and operates to maintain a suit-
able following distance from the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on down-
hill slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle distance can also be set by operating the vehicle-to-vehicle dis-
tance switch.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pressing the
“+ RES” switch or depressing the accelerator pedal will resume follow-up
cruising.

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 system 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. 272)
Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed (at or
above approximately 30 mph
[50 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.
If the switch is operated while the vehicle speed is below approximately 30
mph (50 km/h) and a preceding vehicle is present, the set speed will be
adjusted to approximately 30 mph (50 km/h).
