Static Objects Front and Rear of the vehicle

If the sensors detect a static object, such as a wall, in the travelling direction of the
vehicle and the system determines that a collision may occur due to the vehicle
suddenly moving forward due to an accidental accelerator pedal operation, the
vehicle moving the unintended direction due to the wrong shift position, or while
parking or traveling at low speeds, the system will operate to lessen the impact with
the detected static object and reduce the resulting damage.

Dynamic radar cruise control

This dynamic radar cruise control uses radar to detect the presence of vehicles
ahead, determines the current vehicle-to-vehicle distance, and operates to main-
tain a suitable distance from the vehicle 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 highways 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 control 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 system may not operate correctly:

→

P.447

●

Set the speed appropriately according to the speed limit, traffic flow, road conditions,
weather conditions, etc. The driver is responsible for confirming the set speed.

●

Even if the system is operating correctly, the condition of a preceding 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 precautions, as there are limitations to the assistance provided by
the system. Over-reliance on this system 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 vehicle 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.

WARNING

The dynamic radar cruise control determines whether the distance between the
driver’s own vehicle and a designated preceding vehicle 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 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 safety.

■

Situations in which the dynamic radar cruise control should not be used

Do not use the dynamic radar cruise control in the following situations. As the system will
not be able to provide appropriate control, using it may lead to an accident resulting in
death or serious injury.

Basic functions

6-2. Using the safe driving support functions

444

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 blink 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 vehicle automatically
decelerates and if a greater reduction in vehicle speed is necessary, the brakes are
applied (the stop lights will come on at this time). The vehicle is controlled to maintain
the vehicle-to-vehicle distance set by the driver, in accordance with changes in the
speed of the preceding vehicle. If vehicle deceleration is not sufficient and the vehicle
approaches the vehicle ahead, the approach warning will sound.

Acceleration

When there are no longer any preceding vehicles driving slower than the set vehicle
speed
The vehicle accelerates until the set vehicle speed is reached and then resumes
constant speed cruising.

Starting off:

Vehicles without a head-up display: If a preceding vehicle stops, the vehicle will also
stop (controlled stop). After the preceding vehicle starts off, pressing the [+RES] switch
or depressing the accelerator pedal will resume follow-up cruising (start off operation).
If a start off operation is not performed, the controlled stop will continue.
Vehicles with a head-up display: If a preceding vehicle stops, the vehicle will also stop
(controlled stop). After the preceding vehicle starts off, pressing the [ + ] switch or
depressing the accelerator pedal will resume follow-up cruising (start off operation). If
a start off operation is not performed, the controlled stop will continue.
