Pre-Collision Braking System
21
Continued on next page Ÿ
- 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
37
CAUTION
xAfter Adaptive Cruise Control has started, it maintains control continuously
according to the behavior of the vehicle in front. When your vehicle comes
to a stop if the vehicle in front has stopped, the stay-stopped function is
engaged. However, if the EyeSight stereo cameras lost detection of the
vehicle in front, the system may not stop your vehicle. Operate the brake
pedal and maintain the correct following distance as necessary. Be aware
that the EyeSight system has difficulty detecting objects or vehicles that
have a relative speed in comparison to your vehicle. Therefore, if the
EyeSight system loses detection just as you are approaching a line of
stopped cars, for example - you will have to brake manually.
xThere is no possibility that the vehicle will automatically begin moving from
a stay-stopped condition without operation from the driver.
xIf the conditions for automatically canceling cruise control (
Ÿ refer to page
49) are met while the vehicle is stay-stopped, Adaptive Cruise Control is
canceled and for safety reasons, the electronic parking brake is automati-
cally applied.
xBraking may not be sufficient depending on the following conditions. Oper-
ate the brake pedal and decelerate as necessary.
- Vehicle conditions (amount of load, number of occupants, etc.)
- Road conditions (grade, slipperiness, shape, bumps, etc.)
- Vehicle maintenance status (brake systems, tire wear, air pressure, tem-
porary spare tire is being used, etc.)
- When the brakes are cold. (For example, just after the engine is started
or when the outside temperature is low.)
- For a short period of time when driving after the engine is started until the
engine has warmed-up
- When the brakes are overheated on downhill grades (braking effective-
ness may be reduced)
- When driving in rain or after washing the vehicle (the brakes may
become wet and braking effectiveness may be reduced)
- When towing a trailer or another vehicle, etc.
EyeSight malfunction and temporary stop
88
Displayed screen Cause Action
xWhen the EyeSight sys-
tem is starting
xWhen the system has
determined that the vehi-
cle is extremely inclined
xWhen the pre-collision
secondary braking has
operated 3 times after the
engine was started
xWhen the engine is
stopped
xWhen the electronic
power steering system is
in the overheating preven-
tion status because the
steering wheel has been
operated while the vehicle
is at a standstill or driving
at an extremely slow
speed
xWhen the EyeSight sys-
tem judged a different
value due to the removal
or installation of the steer-
ing wheel
xWhen wheel alignments
are deviatedThe system will restart once
the cause has been elimi-
nated. At this time, it may
take some time for the sys-
tem to restart.
If the system does not
restart, even after the condi-
tions have improved and a
period of time has elapsed,
contact your SUBARU dealer
for an inspection.
NOTE
When the EyeSight temporary stop indicator has illuminated, no EyeSight
functions can be used except for Conventional Cruise Control.
