Pre-Collision Braking System

Pre-Collision Braking System
When there is the risk of a rear-end collision with a obstacle in front, the EyeSight system
helps to minimize or prevent a collision by warning the driver. If the driver still does not take
evasive action to avoid a collision, the brakes can be automatically applied just before the
collision in order to reduce impact damage, or if possible, prevent the collision. When the
system determines that there is a high risk of collision with an obstacle ahead, and the
driver depresses the brake pedal, the system activates braking assist. (Pre-Collision Brake
Assist)
This system can be effective not only with frontal collisions, but also with offset (right or left)
collisions. This function can be activated when the select lever is in the D , M or N positions.
WARNING

Never use the Pre-Collision Braking System and Pre-Collision Brake
Assist to stop your car under ordinary conditions. The Pre-Collision
Braking System cannot prevent collisions under all conditions. If the driver
relies only on the Pre-Collision Braking System for Brake operation, collisions may occur.
When a warning is activated, pay attention to the front of the vehicle and its
surroundings, and operate the brake pedal and/or take other actions if necessary.
The EyeSight Pre-Collision Braking System function is primarily designed
to prevent rear-end collisions with other vehicles when possible and to
minimize damage and injuries in the event of a collision. In addition to
other vehicles, things such as motorbikes, bicycles and pedestrians can
also be treated as obstacles. However, there may be cases when detection is not possible depending on a variety of conditions*. It is highly probable that the Pre-Collision Braking System function does not work against
vehicles parked in a lateral position, oncoming vehicles, backing up vehicles, small animals, infants, fences, walls, gates, etc.
The Pre-Collision Braking System function will operate at the point when it
determines that a collision cannot be avoided and is designed to apply
strong braking force just before a collision. The result of this varies
depending on a variety of conditions*. Because of this, performance of this
function will not always be the same.
When the Pre-Collision Braking System function is activated, it will continue to operate even if the accelerator pedal is partially depressed. However, it will be canceled if the accelerator pedal is fully depressed.
If the driver depresses the brake pedal or turns the steering wheel, the system may determine that this constitutes evasive action by the driver, and
the automatic braking control may not activate in order to allow the driver
full control.
When the difference in speed with the obstacle in front is approximately 20
MPH (30 km/h) or more, it may not be possible to avoid a collision. Even if
the speed difference is approximately 20 MPH (30 km/h) or less, in cases
such as when another vehicle cuts in front of you, or in other cases
depending on visibility, condition of road surface and other factors*, the
function may be unable to stop the vehicle or may not activate. Pre-Collision Brake Assist may also not activate depending on the conditions* listed
below.
*Conditions
- Distance to obstacle in front of you, speed difference, proximity conditions, lateral displacement (the amount of offset)
- Vehicle conditions (amount of load, number of occupants, condition of
tires, etc.)
- Road conditions (grade, slipperiness, shape, bumps, etc.)
- When visibility ahead is poor (rain, snow, fog or smoke, etc.)
- When the detected object is one of the following
• A domestic animal or other animal (a dog or deer, etc.)
• A guardrail, telephone pole, tree, fence or wall, etc.
