Pre-Collision Braking System
21
Continued on next pageŸ
- 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.)
xA 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)
xWhen 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
xWhen driving at night or in a tunnel without the headlights on
xWhen driving at night or in a tunnel when there is a vehicle in front that
does not have its taillights on
xWhen approaching a motorcycle, bicycle or pedestrian at night
xWhen ambient light is poor in the evening or early morning
xWhen a vehicle, motorcycle, bicycle or pedestrian is outside the area
illuminated by the headlights
xWhen affected by strong light from the front (for example, sunlight at
dawn, sunset or headlight beams, etc.)
xWhen there is snow, frost, dirt or dust on the windshield or it is clouded
xWhen fluid has not been fully wiped off the windshield during or after
washer use
xWhen 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.

Adaptive Cruise Control
34
ŸContinued from previous page
- When water droplets from rain or the window washer, or dirt has not
been fully wiped off the windshield
It may not be possible to detect the vehicle in front, making correct con-
trol impossible.
- When the stereo cameras’ field of view is obstructed (for example by a
canoe on the roof of the vehicle)
xThe stereo cameras may have difficulty detecting the following objects or
conditions. Operate the brake pedal and take other actions as necessary.
- Vehicles at significantly different speeds (vehicles driving slowly,
stopped or oncoming vehicles, etc.)
- Vehicles cutting into your lane
- Motorcycles, bicycles, pedestrians and animals, etc.
- When light is poor in the evening or early morning
- When driving at night or in a tunnel without the headlights on
- When driving at night or in a tunnel when there is a vehicle in front that
does not have its taillights on
- When affected by strong light from the front (sunlight or headlight high
beams, etc.)
- Vehicles in front that have
a rear aspect that is low,
small or irregular (the sys-
tem may recognize
another part of the vehicle
and will determine opera-
tion from that)
xAn empty truck or trailer
that has no cargo in the
cargo bed being affected
by wind
xVehicles that have cargo
protruding from their
back ends
xNon-standard shaped ve- hicles (vehicle transporters or vehicles with a
sidecar fitted, etc.)
xVehicles that are low
- Objects that are located close to the bumper of your vehicle
xWhen you do not want to use Adaptive Cruise Control, be sure to turn the
(CRUISE) switch off. If the switch is left on, cruise control may be
accidentally engaged, possibly resulting in an accident.
xBefore using Adaptive Cruise Control, be sure to fully verify the safety of
the vehicle occupants and the area around the vehicle. Never operate the
cruise control from outside the vehicle.

Pre-Collision Throttle Management
63
Continued on next pageŸ
xIf your vehicle is trapped on a railroad crossing and you are trying to
escape by driving through the crossing gate, the stereo cameras may rec-
ognize the crossing gate as an obstacle and Pre-Collision Throttle
Management system may activate. In this case, remain calm and either
continue to depress the accelerator pedal or turn off the Pre-Collision
Throttle Management system.
Ÿ Refer to page 67.
xPre-Collision Throttle Management may not activate depending on the fol-
lowing conditions:
- The distance between your vehicle and the obstacle, speed difference,
and lateral displacement (amount of offset)
- Recognition status of the stereo cameras
In particular, the function may not activate in the following cases:
xBad weather (for example heavy rain, a blizzard or thick fog)
xWhen visibility is poor due to sand or smoke in the air
xWhen light is poor in the evening, early morning, or at night
xIn a dark area (indoor parking area, etc.)
xWhen there is an obstacle outside the area illuminated by the head-
lights
xWhen affected by strong light from the front (for example sunlight at
sunrise or sunset headlight beams, etc.)
xWhen there is snow, frost, dirt or dust on the windshield, or it is clouded
xWhen fluid has not been fully wiped off the windshield during or after
use of the window washer
xWhen obstacles cannot be correctly recognized due to water droplets
from rain or the washer, or the wiper blades obstructing the stereo
cameras’ field of view
xWhen the stereo cameras’ field of view is obstructed (for example by a
canoe on the roof of the vehicle)
xWith low obstacles (low wall, crash barrier, low vehicle, etc.)
xWhen the size and height of an obstacle is smaller than the limitations
of the stereo cameras’ recognition capability
xWith small animals or children.
xWith pedestrians who are sitting or lying down
xWhen the rear portion
nearest your vehicle is
too small or too close
(such as a trailer or
oncoming vehicle) the
system may not recog-
nize the part of that
vehicle which is closest
to you.
