■Enabling/disabling the
pre-collision system
The pre-collision system can be
enabled/disabled on
( P.516) of the multi-informa-
tion display.
The system is automatically
enabled each time the power
switch is turned to ON.
If the system is disabled, the
PCS warning light will turn on
and a message will be displayed
on the multi-information display.
■Changing the pre-collision
warning timing
The pre-collision warning timing
can be changed on
( P.516) of the multi-informa-
tion display.
The warning timing setting is
retained when the power switch is
turned off. Howeve r, if the pre-colli-
sion system is disabled and
re-enabled, the ope ration timing will
return to the default setting (mid-
dle).

■Operational conditions
The pre-collision syst em is enabled and the system determines t hat the pos-
sibility of a frontal c ollision with a detected object is high.
Each function is operatio nal at the following speed
●Pre-collision warning
●Pre-collision brake assist
●Pre-collision braking
Detectable objectsVehicle speedRelative speed between
your vehicle and object
VehiclesApprox. 7 to 110 mph (10 to 180 km/h)Approx. 7 to 110 mph (10 to 180 km/h)

1784-5. Using the driving support systems
COROLLA HV_UThe system may not operate in the following situations:
●If a 12-volt battery te
rminal has been disc onnected and reconne cted and
then the vehicle has not been dr iven for a certain amount of time
●If the shift lever is in R
●When the VSC OFF indicator is illuminated (only the pre-collision warning
function will be operational)
■Object detection function
The system detects objects based
on their size, profile, motion, etc.
However, an object may not be
detected depending on the sur-
rounding brightness and the motion,
posture, and angle of the detected
object, preventing the system from
operating properly. ( P.179)
The illustration sh ows an image of
detectable objects.
■Cancelation of t he pre-collision
braking
If either of the fo llowing occur while
the pre-collision braking function is
operating, it will be canceled:
●The accelerator pedal is
depressed strongly.
●The steering wheel is turned
sharply or abruptly.
■Conditions under which the
system may operate even if
there is no possibility of a colli-
sion
●In some situations such as the fol-
lowing, the system may determine
that there is a possibility of a fron-
tal collision and operate.
• When passing a detectable object, etc.
• When changing lanes while over-
taking a detectable object, etc.
• 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 winding road
• When rapidly closing on a detect- able object, etc.
• When approaching objects on the roadside, such as detectable
objects, guardrails, utility poles,
trees, or walls
• When there is a d etectable object
or other object by the roadside at
the entrance of a curve

■Situations in which the system
may not operate properly

lowing, an object may not be
detected by the radar sensor and
front camera, pre venting the sys-
tem from opera ting properly:
• When a detectable object is approaching your vehicle
• When your vehicle or a detectable object is wobbling

LTA (Lane Tracing
Assist)
When driving on highways
and freeways with white
(yellow) lane lines, this
function alerts the driver
when the vehicle might
depart from its lane or
course
* and provides assis-
tance by operating the
steering wheel to keep the
vehicle in its lane or
course
*. Furthermore, the
system provides steering
assistance when dynamic
radar cruise control with
full-speed range is operat-
ing to keep the vehicle in its
lane.
The LTA system recognizes
white (yellow) lane lines or a
course
* using the front cam-
era. Additionally, it detects
preceding vehicles using
the front camera and radar.
*: Boundary between asphalt and the side of the road, such as
grass, soil, or a curb
WA R N I N G
■Before using LTA system
●Do not rely solely upon the LTA
system. The LTA system does
not automatically drive the vehi-
cle or reduce the amount of
attention that m ust be paid to
the area in front of the vehicle.
The driver must always assume
full responsibilit y for driving
safely by paying careful atten-
tion to the surrounding condi-
tions and operating the steering
wheel to correct the path of the
vehicle. Also, the driver must
take adequate breaks when
fatigued, such as from driving
for a long period of time.
●Failure to perform appropriate
driving operations and pay care-
ful attention may lead to an
accident, result ing in death or
serious injury.
●When not using the LTA system,
use the LTA swit ch to turn the
system off.
■Situations unsuitable for LTA
system
In the following situations, use the
LTA switch to turn the system off.
Failure to do so may lead to an
accident, resulting in death or
serious injury.
●Vehicle is driven on a road sur-
face which is slippery due to
rainy weather, fallen snow,
freezing, etc.
●Vehicle is driven on a snow-cov-
ered road.
●White (yellow) lin es are difficult
to see due to ra in, snow, fog,
dust, etc.
●Vehicle is driven in a temporary
lane or restricted lane due to
construction work.

■Situations unsuitable for
dynamic radar cruise control
with full-speed range
Do not use dynamic radar cruise
control with full-speed range in
any of the following situations.
Doing so may result in inappropri-
ate speed control and could
cause an accident resulting in
death or serious injury.
●Roads where there are pedes-
trians, cyclists, etc.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as
those covered with rain, ice or
snow
●On steep downhills, or where
there are sudden changes
between sharp up and down
gradients
Vehicle speed may exceed the set
speed when driving down a steep
hill.
●At entrances to freeways and
highways
●When weather conditions are
bad enough that they may pre-
vent the sensors from detecting
correctly (fog, snow, sand-
storm, heavy rain, etc.)
●When there is rain, snow, etc.
on the front surface of the radar
or front camera
●In traffic conditions that require
frequent repeated acceleration
and deceleration
●During emergency towing
●When an approach warning
buzzer is heard often

Driving
This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current veh i-
cle-to-vehicle following distance, and operates to maintain a s uitable
following distance from the vehicle ahead. The desired vehi-
cle-to-vehicle distance can also be set by operating the vehi-
cle-to-vehicle distance switch.
When driving on downhill slopes, t he vehicle-to-vehicle distance may
become shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration crui sing and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected runni ng ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle s peed is nec-
essary, the system applies the brakes (the stop lights will come on at this
time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you st ops, your vehicle will also stop (vehicle is
stopped by system control). Afte r the vehicle ahead starts off, pressing the
“+RES” switch or depressing the accelerator pedal (start-off operation) will
resume follow-up cruising. If the start-off operation is not pe rformed, system
control continues to keep your vehicle stopped.
