■Operational conditions for each pre-collision function
The pre-collision system is enabled and the system determines t hat the pos-
sibility of a frontal collision with a detected object is high.
The system may not operate in the following situations:
• If a 12-volt battery terminal has been disconnected and reconn ected and
then the vehicle has not been driven for a certain amount of ti me
• If the shift lever is in R
• When the VSC OFF indicator is illuminated (only the pre-collis ion warning
function will be operational)
The operation speeds and operation cancellation for each functi on is listed
below.
● Pre-collision warning
● Pre-collision brake assist

● Pre-collision braking
If either of the following occur while the pre-collision brakin g function is oper-
ating, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is turned sharply or abruptly.
● Emergency steering assist (for region A)
When the turn signal lights are flashing, emergency steering as sist will not
operate in case of an emergency.
If any of the following occur while the emergency steering assi st function is
operating, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is turned sharply or abruptly.
• The brake pedal is depressed.

● Intersection right/left turn assistance (pre-collision braking) (for region A)

■ Object detection function
The system detects objects based on their size, profile, motion , etc. However,
an object may not be detected depending on the surrounding brig htness and
the motion, posture, and angle of the detected object, preventi ng the system
from operating properly. ( P. 381)
The illustration shows an image of detectable objects.
■ Conditions under which the system may operate even if there is no pos-
sibility of a collision
● In some situations such as the following, the system may determine that
there is a possibility of a frontal collision and operate.
• When passing a detectable object, etc.
• When changing lanes while overtaking a detectable object, etc.
• When rapidly closing on a detectable object, etc.
• When approaching objects on the roadside, such as detectable o bjects,
guardrails, utility pol es, trees, or walls
Region A
Region B
• When approaching a detectable
object in an adjacent lane or on the
roadside, such as when changing the
course of travel or driving on a wind-
ing road

• When there are patterns or paint in front of your vehicle that may be mis-
taken for a detectable object
• When the front of your vehicle is hit by water, snow, dust, et c.
• When a detectable object approaches very close and then stops before
entering the path of your vehicle
• If the front of your vehicle is raised or lowered, such as whe n on an
uneven or undulating road surface
• When driving on a road surrounded by a structure, such as in a tunnel or
on an iron bridge
• When there is a metal object (manhole cover, steel plate, etc. ), steps, or a
protrusion in front of your vehicle
• When there is a detectable object or
other object by the roadside at the
entrance of a curve
• When overtaking a detectable object
that is changing lanes or making a
right/left turn
• When passing a detectable object in
an oncoming lane that is stopped to
make a right/left turn
• When passing under an object (road
sign, billboard, etc.)

3804-5. Using the driving support systems

• When approaching an electric toll gate barrier, parking area b arrier, or
other barrier that opens and closes
• When using an automatic car wash
• When driving through steam or smoke
• When driving near an object that reflects radio waves, such as a large
truck or guardrail
• When driving near a TV tower, broadcasting station, electric p ower plant,
radar equipped vehicles, etc., or o ther location where strong radio waves
or electrical noise may be present
• When there are many things which can reflect the radio waves o f the
radar in the vicinity (tunnels, truss bridges, gravel roads, sn ow covered
road that have tracks, etc.)
• For region A: While making a right/left turn, when an oncoming vehicle or
a crossing pedestrian has already exited the path of your vehic le
• For region A: While making a right/left turn, closely in front of an oncom-
ing vehicle or a crossing pedestrian
• For region A: While making a right/left turn, when an oncoming vehicle or

■ Situations in which the system may not operate properly
● In some situations such as the following, an object may not be detected by
the radar sensor and front camera, preventing the system from o perating
properly:
• When a detectable object is approaching your vehicle
• When your vehicle or a detectable object is wobbling
• If a detectable object makes an abrupt maneuver (such as sudde n swerv-
ing, acceleration or deceleration)
• When your vehicle approaches a detectable object rapidly
• When a detectable object is near a wall, fence, guardrail, man hole cover,
vehicle, steel plate on the road, etc.
• When a detectable object is under a structure
• When part of a detectable object is hidden by an object, such as large
baggage, an umbrella, or guardrail
• When there are many things which can reflect the radio waves o f the
radar in the vicinity (tunnels, truss bridges, gravel roads, sn ow covered
road that have tracks, etc.)
• When there is an effect on the radio waves to the radar that i s installed on
another vehicle
• When multiple detectable objects are close together
• If the sun or other light is shining directly on a detectable object
• When a detectable object is a shade of white and looks extreme ly bright
• When a detectable object appears to be nearly the same color o r bright-
ness as its surroundings
• If a detectable object cuts or suddenly emerges in front of yo ur vehicle
• When the front of your vehicle is hit by water, snow, dust, et c.
• When a very bright light ahead, such as the sun or the headlig hts of
oncoming traffic, shines dir ectly into the front camera
• When approaching the side or front of a vehicle ahead
• If a vehicle ahead is a motorcycle
• If a vehicle ahead is narrow, such as a personal mobility vehi cle
• If a preceding vehicle has a small rear end, such as an unload ed truck
• When a detectable object is not
directly in front of your vehicle

• If a vehicle ahead is carrying a load which protrudes past its rear bumper
• If a vehicle ahead is irregularly shaped, such as a tractor or side car
