QCancelation of the pre-collision
braking
If either of the following occur while the pre-collision braking function is operat-
ing, it will be canceled:
OThe accelerator pedal is depressed
strongly.
OThe steering wheel is turned sharply
or abruptly.
QConditions under which the system may operate even if there is no pos-sibility of a collision
OIn some situations such as the follow-ing, the system may determine that
there is a possibility of a frontal colli- sion and operate.• When passing a detectable object,
etc. • When changing lanes while overtak-ing 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 wind- ing road
• When rapidly closing on a detectable object, etc.• When approaching objects on the
roadside, such as detectable objects,
guardrails, utility poles, trees, or walls
• When there is a detectable object or other object by the roadside at the entrance of a curve
• 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, etc.
• 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 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 when 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

*: If equipped
LTA (Lane Tracing
Assist)
*
While driving on a road with
clear white (yellow) lane lines,
the LTA system warns the
driver if the vehicle may devi-
ate from the current lane or
course
*, and also can slightly
operate the steering wheel to
help avoid deviation from the
lane or course
*. Also, while the
dynamic radar cruise control
with full-speed range is operat-
ing, this system will operate
the steering wheel to maintain
the vehicle’s lane position.
The LTA system recognizes
white (yellow) lane lines or a
course
* using the front cam-
era. Additionally, it detects pre-
ceding vehicles using the front
camera and radar.
*: Boundary between asphalt and the
side of the road, such as grass,
soil, or a curb

WARNING
QBefore using LTA system
ODo not rely solely upon the LTA
system. The LTA system does not automatically drive the vehicle or reduce the amount of attention that
must be paid to the area in front of the vehicle. The driver must always assume full responsibility for driving
safely by paying careful attention to the surrounding conditions and operating the steering wheel to cor-
rect the path of the vehicle. Also, the driver must take adequate breaks when fatigued, such as from
driving for a long period of time.
OFailure to perform appropriate driv-
ing operations and pay careful attention may lead to an accident, resulting in death or serious injury.
OWhen not using the LTA system, use the LTA switch to turn the sys-
tem off.
QSituations 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 acci- dent, resulting in death or serious injury.
OVehicle is driven on a road surface which is slippery due to rainy
weather, fallen snow, freezing, etc.
OVehicle is driven on a snow-cov-
ered road.
OWhite (yellow) lines are difficult to
see due to rain, snow, fog, dust, etc.
OVehicle is driven in a temporary lane or restricted lane due to con-struction work.
OVehicle is driven in a construction zone.
OA spare tire, tire chains, etc. are equipped.
OWhen the tires have been exces-sively worn, or when the tire infla-tion pressure is low.
OWhen your vehicle is towing a trailer or during emergency towing
QPreventing LTA system malfunc-tions and operations performed
by mistake
ODo not modify the headlights or place stickers, etc. on the surface of
the lights.
ODo not modify the suspension etc. If
the suspension etc. needs to be replaced, contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
ODo not install or place anything on
the hood or grille. Also, do not install a grille guard (bull bars, kan-garoo bar, etc.).
OIf your windshield needs repairs, contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
QConditions in which functions may not operate properly
In the following situations, the func-
tions may not operate properly and the vehicle may depart from its lane. Drive safely by always paying careful
attention to your surroundings and operate the steering wheel to correct the path of the vehicle without relying
solely on the functions.

the steering wheel vibrates, check the
area around your vehicle and carefully
operate the steering wheel to move the
vehicle back to the center of the lane.
Vehicles with BSM: When the system
determines that the vehicle might
depart from its lane and that the possi-
bility of a collision with an overtaking
vehicle in the adjacent lane is high, the
lane departure alert will operate even if
the turn signals are operating.
*: Boundary between asphalt and the

the vehicle might depart from its
lane or course
*, the system pro-
vides assistance as necessary by
operating the steering wheel in
small amounts for a short period of
time to keep the vehicle in its lane.
If the system detects that the steering wheel has not been operated for a fixed
amount of time or the steering wheel is
not being firmly gripped, a warning is
displayed on the multi-information dis-
play and the function is temporarily
canceled.

visible, such as when in a traffic jam,
this function will operate to help follow a
preceding vehicle by monitoring the
position of the preceding vehicle.
If the system detects that the steering
wheel has not been operated for a fixed
amount of time or the steering wheel is
not being firmly gripped, a warning is
displayed on the multi-information dis-
play and the function is temporarily canceled.
