Pre-Collision Braking System
44
ŸContinued from previous page
- 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 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.
• Bad weather (for example heavy rain, a blizzard or thick fog)
• 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
• 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 approaching a motorcycle, bicycle or pedestrian at night
• When ambient light is poor in the evening or early morning
• When a vehicle, motorcycle, bicycle or pedestrian is outside the area
illuminated by the headlights
• When affected by strong light from the front (for example, sunlight at
dawn, sunset or headlight high beams, etc.)
• When there is snow, frost, dirt or dust on the windshield or it is clouded
• When fluid has not been fully wiped off the windshield during or after
washer use
• 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.
• When the stereo cameras’ field of view is obstructed (for example by a
canoe on the roof of the vehicle)
• When the rear aspect of
the vehicle in front is
low, small or irregular
(the system may recog-
nize another part of the
vehicle as its rear and
will determine operation
from that)
- When there is an
empty truck or trailer
with no rear and/or
side panels on the
cargo bed
- With vehicles that
have cargo protruding
from their back ends
- With non-standard
shaped vehicles (vehicle transporters or vehicles with a sidecar
fitted, etc.)
- When the height of the vehicle is low, etc.

• When there is a wall, etc. in front of a stopped vehicle
• When there is another object near the vehicle
• When a vehicle, etc. is stopped in the lateral direction
• With vehicles that are backing up or with oncoming vehicles, etc.
• When the size and height of an obstacle is smaller than the limitations
of the stereo cameras’ recognition capability
- With small animals or children, etc.
- With pedestrians who are sitting or lying down
• When the detected
object is a fence, wall or
shutter, etc.
• When there is a wall or
door made of glass or a
mirror in front
• When the vehicle in front
suddenly swerves,
accelerates, or deceler-
ates.
• When a vehicle, motor-
cycle, bicycle or pedes-
trian cuts in from the
side or jumps out sud-
denly
• When you suddenly
change lanes and your
vehicle is immediately
behind an obstacle
• When there is a vehicle, motorbike, bicycle or pedestrian in a location
extremely close to your vehicle
• When the speed difference between your vehicle and an obstacle is 4
MPH (5 km/h) or less (As braking is performed once the obstacle is in
close proximity to your vehicle, depending on the shape and size of the
obstacle, there may be some cases when the obstacle is outside the
range of the cameras’ field of vision.)
• When driving on sharp curves, steep uphill grades or steep downhill
grades
• When driving on a bumpy or unpaved road
• When passing through the entrance or exit of a tunnel
lxFor your safety, do not test the Pre-Collision Braking System function by
yourself. There is a possibility that the vehicle will not stop or the function
will not work during the test and this may cause an unexpected accident.
xThe system may not operate correctly under the conditions listed below.
When these conditions occur, turn off the Pre-Collision Braking System.
- The tire pressure is not correct.*
- A temporary spare tire is installed.*
- Tires that are worn or have large variations in wear conditions.*
- Tires other than those of the designated size are installed.*
- Flat tires are repaired using the flat tire repair kit.
- The suspension has been modified.
- Tire chains are installed.
- The headlights are dirty or are not aligned correctly. (Objects are not cor-
rectly illuminated and are difficult to detect.)
- Vehicle operation has become compromised due to an accident or mal-
function.
- The brake warning light is illuminated.
- The vehicle is tilted due to a heavy cargo load.
- The maximum number of occupants and/or the gross vehicle weight rat-
ing has been exceeded.
*The wheels and tires have functions that are critically important. Be sure
to use the correct parts. For details, refer to the Owner’s Manual for your
vehicle.

Pre-Collision Braking System
49
When there is an obstacle in the forward direction during driving, the system activates in the
following sequence in order to warn the driver, activate braking control, and active the brake
lights.
(1) Following Distance Warning:
When the system determines that there is a risk of collision, a buzzer sounds repeated short
beeps and the indicators on the meter display and the multi function display illuminate to
warn the driver.
The Following Distance Warning operates when Adaptive Cruise Control is not set.
When the driver depresses the brake pedal to decelerate and achieves a suitable following
distance, the warning is canceled.
(2) First Braking and Warning:
When the system determines that there is a high risk of collision with an obstacle in front, a
buzzer sounds repeated short beeps and the indicators on the meter display and the multi
function display illuminate to warn the driver, and braking control is activated. If the system
determines that the amount of evasive action (braking, steering, etc.) taken by the driver
has reduced the risk of collision, braking activation is canceled.
(3) Second Braking and Warning:
If the system then determines that the risk of collision is extremely high, the buzzer changes
to a continuous beeping sound and stronger braking control is activated. If, despite any eva-
sive action taken by the driver, the system subsequently determines that a collision is
unavoidable, braking control is continued.
When the vehicle stops, a buzzer sounds three short beeps and a single long beep. The
automatic braking function is cancelled approximately 2 seconds after the vehicle stops and
the vehicle starts creeping forward gradually.

Pre-Collision Throttle Management
53
Continued on next page Ÿ
xPre-Collision Throttle Management will not reduce acceleration under all
conditions. It is also not designed to prevent collisions.
xPre-Collision Throttle Management will operate when an obstacle is
detected in front. However, this function will not reduce acceleration in
cases where no obstacle is recognized (for example when approaching a
cliff, etc.)
xDo not intentionally depress the accelerator pedal excessively when there
are obstacles nearby. If the driver relies only on Pre-Collision Throttle
Management to control acceleration, collisions may occur.
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.
* Refer to page 57.
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:
• Bad weather (for example heavy rain, a blizzard or thick fog)
• When visibility is poor due to sand or smoke in the air
• When light is poor in the evening, early morning, or at night
• In a dark area (indoor parking area, etc.)
• When there is an obstacle outside the area illuminated by the head-
lights
• When affected by strong light from the front (for example sunlight at
sunrise or sunset headlight high beams, etc.)
• When there is snow, frost, dirt or dust on the windshield, or it is clouded
• When fluid has not been fully wiped off the windshield during or after
use of the window washer
• When obstacles cannot be correctly recognized due to water droplets
from rain or the washer, or the wiper blades obstructing the stereo cam-
eras’ field of view
• When the stereo cameras’ field of view is obstructed (for example by a
canoe on the roof of the vehicle)
• With low obstacles (low wall, crash barrier, low vehicle, etc.)
• When the size and height of an obstacle is smaller than the limitations
of the stereo cameras’ recognition capability
• With small animals or children
• With pedestrians who are sitting or lying down

Troubleshooting
86
EyeSight does not restart after a temporary stop.
Is Vehicle Dynamics Control turned off?
EyeSight cannot be activated when Vehicle Dynamics Control is off.
Is the X-mode turned on?
EyeSight cannot be activated when the X-mode is turned on.
Are you driving in the rain with old wipers or is there an oily film on the windshield?
Replace the wipers with new ones, or clean the oily film off the windshield.
Is your vehicle subject to sunlight from the front (sunset or sunrise, etc.) or to
bright headlights from oncoming vehicles at nighttime?
In these cases, EyeSight may temporarily stop operating.
The timing of the “brake more” warning is sometimes earlier and sometimes later
than what seems to be normal operation.
The “brake more” warning sounds when the system determines that more braking
is necessary, based on conditions such as the distance from the vehicle in front
and the difference in speed. As a result, timing may vary depending on how the
brake of the vehicle in front is applied.
Acceleration is sometimes slower and sometimes faster when the vehicle in front
is no longer detected.
Depending on the timing of when the detection of the vehicle in front is lost,
EyeSight’s ability to react may be slower, causing the start of acceleration to feel
delayed and braking time to feel longer than what seems to be normal operation.
Which SI-DRIVE mode is selected?
The acceleration varies due to the characteristics change of Adaptive Cruise Con-
trol depending on which mode is selected.
Cruise control is canceled automatically.
Did you perform one of the following operations?
xManually depressing the brake pedal
xPressing the CANCEL switch for cruise control
xOperating the paddle shift lever
xShifting the selector lever to the position
xPressing the Vehicle Dynamics Control OFF switch (VDC OFF indicator
illuminates.)
xPressing the X-mode switch (X mode indicator illuminates.)
Has the EyeSight system temporarily stopped?
