Situations in which the emergency sup-
port brake may not operate properly
In some situations, such as the following,
a detectable object may not be detected
by the sensors, and this function may not
operate properly:
• When a detectable object is approaching
your vehicle
• When your vehicle or a detectable object
is wandering
• If a detectable object makes an abrupt
maneuver (such as sudden swerving,
acceleration or deceleration)
• When suddenly approaching a detect-
able object
• When a detectable object is not directly
in front of your vehicle
• When the detectable object is near a
wall, fence, guardrail, manhole cover,
steel plate on the road surface, or
another vehicle
• When there is a structure above a detect-
able object
• When part of a detectable object is hid-
den by another object (guardrail, etc.)
• When multiple detectable objects are
overlapping
• When a bright light, such as the sun, is
reflecting off of the detectable object
• When the detectable object is white and
looks extremely bright
• When the color or brightness of the
detectable object causes it to blend in
with its surroundings
• When a detectable object cuts in front of
or emerges from beside a vehicle
• When water, snow, dust, etc. is thrown up
in front of the vehicle
• When a very bright light in front of the
vehicle, such as the sun or the headlights
of an oncoming vehicle, shines directly
into a camera or sensor
• When the headlights are not illuminated
while driving at night or when in a tunnel
• When approaching the side or front of a
detectable object
• When a vehicle ahead is a motorcycle
• If a detectable object is narrow, such as a
small mobility vehicle
• If a detectable object has a small rear
end, such as an unloaded truck
• If a detectable object has a low rear end,
such as a low bed trailer
• If a detectable object has extremely high
ground clearance
• If a detectable object is carrying a load
which protrudes from its cargo area
• If a detectable object is irregularly
shaped, such as a sidecar
• When driving in inclement weather (rain,
fog, snow, sandstorm, etc.)
• When driving through steam or smoke
• When a detectable object blends in with
the surrounding area, such as when it is
dim (at dawn or dusk) or dark (at night or
in a tunnel)
• When driving in a place where the sur-
rounding brightness changes suddenly,
such as at the entrance or exit of a tunnel
• When the vehicle has not been driven for
a certain amount of time after the hybrid
system was started
• While driving around a curve and a few
seconds after driving around a curve
• If your vehicle is skidding
