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 pay-

ing careful attention to your surround-

ings.

●

The dynamic radar cruise control with

full-speed range provides driving

assistance to reduce the driver’s bur-

den. However, there are limitations to

the assistance provided.

Read the following conditions care-

fully. Do not overly rely on this system

and always drive carefully.

• When the sensor may not be correctly

detecting the vehicle ahead:

P.244

• Conditions under which the vehi-

cle-to-vehicle distance control mode

may not function correctly:



P.245

●

Set the speed appropriately depend-

ing 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 solely 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 con-

trol with full-speed range setting to off,

using the “ON/OFF” button 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 follow-

ing 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 vehi-

cle and a designated vehicle traveling

ahead. It is not a mechanism 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

necessary for the driver to remain vigi-

lant 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 func-

tions which will prevent or avoid colli-

sions with vehicles ahead of your vehicle.

Therefore, if there is ever any possibility

of danger, the driver must take immedi-

ate and direct control of the vehicle and

act appropriately in order to ensure the

safety of all involved.

Driving

328 ft. (100 m) ahead, determines the current vehicle-to-vehicle following dis-
tance, and operates to maintain a suitable following distance from the vehicle
ahead. The desired vehicle-to-vehicle distance can also be set by operating the
vehicle-to-vehicle distance switch.

When driving on downhill slopes, the vehicle-to-vehicle distance may become shorter.

Example of constant speed cruising
When there are no vehicles ahead

The vehicle travels at the speed set by the driver.

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 sufficiently 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 sys-
tem control). After the vehicle ahead starts off, pushing the cruise control lever up or
depressing the accelerator pedal (start-off operation) will resume follow-up cruising. If the
start-off operation is not performed, system control continues to keep your vehicle
stopped.
When the turn signal lever is operated and your vehicle moves to an overtaking lane while
driving at 50 mph (80 km/h) or more, the vehicle will accelerate to help to overtake a
passing vehicle.
The system’s identification of what is an overtaking lane may be determined 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 from where the vehicle is normally driven, the vehicle may accelerate when the turn

signal lever is operated in the opposite direction to the overtaking lane (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 system then returns to constant
speed cruising.

Press the “ON/OFF” button to acti-
vate the cruise control.

After the vehicle ahead of you starts
off, push the lever up.
Your vehicle will also resume follow-up
cruising if the accelerator pedal is
depressed after the vehicle ahead of
you starts off.

Pulling the lever toward you 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 con-
trol, depressing the brake pedal does not
cancel the setting.)

Pushing the lever up resumes the
cruise control and returns vehicle
speed to the set speed.

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 vehi-
cle-to-vehicle distance.

BSM (Blind Spot Monitor)

The Blind Spot Monitor is a system
that uses rear side radar sensors
installed on the inner side of the
rear bumper on the left and right
side to assist the driver in confirm-
ing safety when changing lanes.

WARNING

■

Cautions regarding the use of the sys-

tem

The driver is solely responsible for safe

driving. Always drive safely, taking care

to observe your surroundings.
The Blind Spot Monitor is a supplemen-

tary function which alerts the driver that a

vehicle is in a blind spot of the outside

rear view mirrors or is approaching rap-

idly from behind into a blind spot. Do not

overly rely on the Blind Spot Monitor. As

the function cannot judge if it is safe to

change lanes, over reliance could lead to

an accident resulting in death or serious

injury.
As the system may not function correctly

under certain conditions, the driver’s own

visual confirmation of safety is necessary.
