Low Speed Braking Control

Continued

Driving

Low Speed Braking Control

The Low Speed Braking Control system has three functions: Low Speed Brake,
Collision Mitigation Throttle Control, and Rear Collision Mitigation Throttle Control.
Using sonar sensors located on the front and rear bumpers, the vehicle detects if
there danger of collision with a wall or other obstacle when the accelerator is
depressed with too much force, and the system assists in avoiding collisions and
reducing damage from impact by limiting power system output.

Low Speed Braking Control

When trapped in a railway crossing, the system may
detect the crossing gate as an obstacle and activate.
If this happens, Low Speed Brake will automatically
cancel after a certain amount of time after stopping,
so continue to move forward. If Collision Mitigation
Throttle Control is activated, continue to calmly
depress the accelerator or depress the accelerator
once again, then push aside the crossing gate.

If the system is activated by curbs/parking curbs or
level differences on the road and you are unable to
park or clear them, turn the system off.

WARNING

It is not possible for the Low Speed Braking
Control system to avoid collisions or reduce
damage from collisions in all situations
where the accelerator has been depressed
accidentally or with too much force.
Over reliance on this system may result in a
collision and serious injury or death.
It is your responsibility to always check your
shift position, pedal location and
surroundings, and safely operate the
vehicle.

Driving

Low Speed Brake function

The Low Speed Brake function provides a visual and audible alert when the vehicle
is moving between approximately 2 and 10 km/h (1 and 6 mph) and there is the
possibility of a collision with a wall or other obstacle, as well as providing assistance
with braking.

How the System Works

Low Speed Braking Control

For directions on the proper handling of the sonar
sensors, please refer to the following page.

Sonar Sensors

P. 497

In order to prevent the system from activating when
not needed, always turn it off during vehicle
maintenance, when loading on ships, trucks, and so
on, or when using a chassis dynamometer or free
rollers for inspection.

Do not make any modifications to the suspension.
The system may not operate correctly.

Always use the size and type of tyres recommended,
make, and amount of wear. If these differ, the system
may not operate correctly.

Collision Mitigation Throttle Control and Rear Collision Mitigation Throttle
Control

When the vehicle is stopped or moving at less than 10 km/h (6 mph) and there is an
obstacle such as a wall near the front of or back of the vehicle, if the accelerator is
depressed more than necessary, the system will inform you with a visual and audible
alert. At the same time, the system will prevent sudden forward or backwards
movement by limiting the output of the power system, then Low Speed Brake will
activate.

Collision Mitigation Throttle Control and Rear Collision Mitigation Throttle Control
will not activate in the following situations.
When moving forward:
When on a steep slope or the shift position is in

Conditions for Collision Mitigation Throttle Control, and Rear Collision Mitigation
Throttle Control.

•

When the accelerator is no longer depressed.

•

When the accelerator is depressed for approximately four seconds.

•

When the brake pedal is depressed.

•

When the steering wheel is turned and a collision avoided.

Conditions for Low Speed Brake function cancellation.

•

A certain amount of time has passed since activation.

The system may not operate correctly in the following conditions:

■

Examples of obstacles the sonar sensor cannot detect

•

Obstacles that do not reflect sound waves well, such as people, snow, cloth,
sponges, etc.

•

Thin obstacles such as fences, bicycles, sign posts, etc.

•

Short or small obstacles.

•

Obstacles immediately in front of the bumper.

•

Moving objects or obstacles that suddenly enter the road.

•

Obstacles that are not perpendicular to the ground, such as a wall.

Conditions for Cancellation

■

Low Speed Braking Control System Conditions and Limitations

Conditions for Cancellation

After Low Speed Brake and Collision Mitigation
Throttle Control have activated once, they will not
activate again for the same obstacle.
They can be activated again after driving for some
time after the last activation.

Low Speed Brake and (Rear) Collision Mitigation
Throttle Control activate separately when moving
forward and reversing. (For example, if it activates
when moving forward, it can be activated again
immediately if reversing.)
However, if Low Speed Brake has been activated, in
order to activate Collision Mitigation Throttle Control
again, it is necessary to drive for a certain amount of
time.

Adaptive Cruise Control (ACC) with Low Speed Follow

Helps to maintain a constant vehicle speed and a set following-interval behind a
vehicle detected ahead of yours and, if the detected vehicle comes to a stop, can
decelerate and stop your vehicle, without you having to keep your foot on the brake
or the accelerator.
When ACC with Low Speed Follow slows your vehicle by applying the brakes, your
vehicle’s brake lights will illuminate.

Adaptive Cruise Control (ACC) with Low Speed Follow

Important Reminder

As with any system, there are limits to ACC with Low
Speed Follow. Use the brake pedal whenever
necessary, and always keep a safe interval between
your vehicle and other vehicles.

For directions on the proper handling of the radar
sensor, refer to the following page.

Radar Sensor

P. 496

WARNING

Improper use of ACC with Low Speed
Follow can lead to a crash.

Use ACC with Low Speed Follow only when
driving on motorways and in good weather
conditions.

WARNING

ACC with Low Speed Follow has limited
braking capability and may not stop your
vehicle in time to avoid a collision with a
vehicle that quickly stops in front of you.

Always be prepared to apply the brake
pedal if the conditions require.

The camera is located behind the rearview mirror.

The radar sensor is located in the front grille.
Be careful not to hit the radar sensor cover. Strong impact can damage it.
