Pre-Collision Braking System
When there is the risk of a rear-end collision with an obstacle in front, the EyeSight system
helps to prevent or minimize 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. If the driver
takes evasive action to avoid a collision, Pre-Collision Brake Assist will operate in order to
help the driver to prevent or minimize the collision.
This system can be effective not only with direct rear-end collisions, but also with offset
rear-end collisions. This function can be activated when the select lever is in the D , M or
N positions.
WARNING
x Never use the Pre-Collision Braking System and Pre-Collision Brake Assist
to stop your car or avoid a collision under ordinary conditions. These func-
tions cannot prevent collisions under all conditions. If the driver relies only on
the Pre-Collision Braking System for Brake operation, collisions may occur.
x 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 nec-
essary.
x The EyeSight Pre-Collision Braking System is primarily designed to prevent
rear-end collisions with other vehicles when possible or 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 obsta-
cles. However, there may be cases when detection is not possible depend-
ing on a variety of conditions *2 . For example, when a vehicle is viewed from
the side, oncoming vehicle, vehicles approaching in reverse, small animals
or children, or walls or doors are not likely to be detected.
x The Pre-Collision Braking System will operate at the point when it deter-
mines 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 *2 . Because of this, performance of this function will not
always be the same.
x When the Pre-Collision Braking System is activated, it will continue to oper-
ate even if the accelerator pedal is partially depressed. However, it will be
canceled if the accelerator pedal is suddenly or fully depressed.
x If the driver depresses the brake pedal or turns the steering wheel, the sys-
tem 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.
x When the difference in speed with the obstacle in front is the following fig-
ure *1 or more, it may not be possible to avoid a collision. Even if the speed
difference is the following figure *1 or less, in cases such as when another
vehicle cuts in front of you, or in other cases depending on visibility, the con-
dition of road surface and other factors *2 , the function may be unable to stop
the vehicle or may not activate. Pre-Collision Brake Assist also may not acti-
vate depending on the conditions *2 listed below.
*1: For vehicles: approximately 30 MPH (50 km/h),
For pedestrians: approximately 20 MPH (35 km/h)
*2: 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, etc.)
- Road conditions (grade, slipperiness, shape, bumps, etc.)
- When visibility ahead is poor (rain, snow, fog or smoke, etc.)
