Pre-Collision Braking System
When there is the risk of a rear-end collision with an 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. If the driver
takes evasive action to avoid a collision, Pre-Collision Brake Assist will operate in order to
help the driver to prevent 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 , or positions.
WARNING
xNever use the Pre-Collision Braking System and Pre-Collision Brake Assist to
stop your car or avoid a collision under ordinary conditions. These functions
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 pre-
vent rear-end collisions with other vehicles when possible and to minimize
damage and injuries in the event of a collision. In addition to other vehi-
cles, 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
*2. For example, when a vehi-
cle 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
operate even if the accelerator pedal is partially depressed. However, it will
be canceled if the accelerator pedal is deeply depressed.
x 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 auto-
matic 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
condition 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 activate depending on the conditions
*2 listed below.
*1:For vehicles: approximately 30 MPH (50 km/h),
For pedestrians: approximately 21 MPH (35 km/h)
*2:Conditions
- Distance to obstacle in front of you, speed difference, proximity condi-
tions, 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.)
- When the detected object is something other than a vehicle, motorcycle,
bicycle or pedestrian
xA domestic animal or other animal (a dog or deer, etc.)
x A guardrail, telephone pole, tree, fence or wall, etc.
- Even if the obstacle is a motorcycle, bicycle or pedestrian, depending on the brightness of the surroundings as well as the relative movement, and
aspect or angle of the object, there may be cases when the system can-
not detect it.
- When the system determines that operation by the driver (based on accelerator pedal operation, braking, steering wheel angle, etc.) is
intended as evasive action
- Vehicle maintenance status (brake systems, tire wear, tire pressure, whether a temporary spare tire is being used, etc.)
- When towing a trailer or another vehicle, etc.
- When the brakes are cold due to outside temperature being low or just after starting the engine.
- When the brakes are overheated on downhill grades (braking effective- ness is reduced)
- When driving in rain or after washing the vehicle (the brakes are wet and braking effectiveness is reduced)
- Recognition conditions of the stereo cameras In particular, the function may be unable to stop the vehicle or may not
activate in the following cases.
xBad weather (for example heavy rain, a blizzard or thick fog)
x When visibility is poor due to sand, smoke or water vapor in the air or
when the vehicle in front or oncoming traffic causes water, snow, dirt,
dust or other substances to obscure the view through the windshield
x When driving at night or in a tunnel without the headlights on
x When driving at night or in a tunnel when there is a vehicle in front that
does not have its taillights on
x When approaching a motorcycle, bicycle or pedestrian at night
x When ambient light is poor in the evening or early morning
x When a vehicle, motorcycle, bicycle or pedestrian is outside the area
illuminated by the headlights
x When affected by strong light from the front (for example, sunlight at
dawn, sunset or headlight beams, etc.)
x When there is snow, frost, dirt or dust on the windshield or it is clouded
x When fluid has not been fully wiped off the windshield during or after
washer use
x When the target cannot be correctly recognized because the stereo
cameras’ view is obstructed by water droplets from rain or the window
washer, or by the wiper blades.
