4-5. Using the driving support systems

iving

This mode employs a radar sensor to detect the presence of vehicles up to
approximately 400 ft. (120 m) ahead, determines the current vehicle-to-vehicle
following distance, and operates to maintain a suitable following distance from
the vehicle ahead.

Note that vehicle-to-vehicle distance will close in when traveling on long downhill

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 dis-

tance can also be set by operating the vehicle-to-vehicle distance control.

Example of deceleration cruising
When the vehicle ahead is driving slower than the set speed

When a vehicle is detected running ahead of you, the system automatically deceler-

ates your vehicle. When a greater reduction in vehicle speed is necessary, the system

applies the brakes. A warning tone warns you when the system cannot decelerate suf-

ficiently to prevent your vehicle from closing in on the vehicle ahead.

Example of follow-up cruising
When following a vehicle driving slower than the set speed

The system continues follow-up cruising while adjusting for changes in the speed of

the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by the driver.

Example of acceleration
When there are no longer any vehicles ahead driving slower than the set
speed

The system accelerates until the set speed is reached. The system then returns to con-

stant speed cruising.

Driving in vehicle-to-vehicle distance control mode

196

4-5. Using the driving support systems

When your vehicle is too close to a vehicle ahead, and sufficient automatic
deceleration via the Dynamic radar 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. Apply the
brakes to ensure an appropriate vehicle-to-vehicle distance.

■

Warnings may not occur when
In the following instances, there is a possibility that the warnings will not occur:

●

When the speed of the vehicle ahead matches or exceeds your vehicle
speed

●

When the vehicle ahead is traveling at an extremely slow speed

●

Immediately after the cruise control speed was set

●

At the instant the accelerator is applied

Constant speed control mode differs from vehicle-to-vehicle distance control
mode. When constant speed control mode is selected, your vehicle will maintain
a set speed regardless of whether or not there are other vehicles in the lane
ahead.

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

Press the button again to deactivate the

cruise control.

Switch to constant speed control
mode.
(Push the lever forward and hold for
approximately one second.)

Cruise control indicator will come on.
When in constant speed control mode, to return to vehicle-to-vehicle distance con-

trol mode, push the lever forward again and hold for approximately 1 second.

After the desired speed has been set, it is not possible to return to vehicle-to-vehicle

distance control mode.

If the power switch is turned off and then turned to ON mode again, the vehicle will

automatically return to vehicle-to-vehicle distance control mode.

WARNING

■

Before using dynamic radar cruise control
Do not overly rely on vehicle-to-vehicle distance control.

Be aware of the set speed. If automatic deceleration/acceleration is not appropriate,

adjust the vehicle speed, as well as the distance between your vehicle and vehicles

ahead by applying the brakes etc.

■

Cautions regarding the driving assist systems
Observe the following precautions.

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 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 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 determines whether the following distance

between the driver’s own vehicle and a designated vehicle traveling ahead is appro-

priate or not. 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 in any given situation.

●

Assisting the driver to operate the vehicle

The dynamic radar cruise control has no capability 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 control of the vehicle and act appropriately in order to ensure

the safety of all involved.
