However, if the pre-collision system is
disabled and re-enabled, the operation
timing will return to the default setting
(middle).
For region A: If the pre-collision
warning timing is changed, emer-

*: If equipped
While driving on a road with clear
white (yellow) lane lines, the LTA
system warns the driver if the vehi-
cle may deviate from the current
lane*, and also can slightly operate
the steering wheel to help avoid
deviation from the lane*. Also, while
the dynamic radar cruise control
with full-speed range is operating,
this system will operate the steering
wheel to maintain the vehicle’s lane
position.
The LTA system recognizes white
(yellow) lane lines* using the front
camera. Additionally, it detects pre-
ceding vehicles using the front
camera and radar.
*: May recognize the boundaries
between the asphalt and the side of
the road, such as grass, soil, or the
curb, to be road lanes.

WARNING
■Before using LTA system
●Do not rely solely upon the LTA sys-
tem. 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.
●Failure to perform appropriate driv-
ing operations and pay careful attention may lead to an accident, resulting in death or serious injury.
■Situations unsuitable for LTA system
In the following situations, use the LTA switch to turn the system off. Fail-ure to do so may lead to an accident,
resulting in death or serious injury.
●Vehicle is driven on a road surface
which is slippery due to rainy weather, fallen snow, freezing, etc.
●Vehicle is driven on a snow-cov-ered road.
●White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.
●Vehicle is driven in a temporary lane or restricted lane due to con-
struction work.
●Vehicle is driven in a construction
zone.
●A spare tire, tire chains, etc., are
equipped.
●When the tires have been exces-
sively worn, or when the tire infla- tion pressure is low.
●When your vehicle is towing a trailer or during emergency towing.
■Preventing LTA system malfunc-tions and operations performed by mistake
●Do not modify the headlights or place stickers, etc., on the surface of the lights.
●Do 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.
●Do not install or place anything on the hood or grille. Also, do not
install a grille guard (bull bars, kan- garoo bar, etc.).
●If your windshield needs repairs, contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
■Conditions 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.
●When the follow-up cruising dis-play is displayed ( P.248) and the
preceding vehicle changes lanes. (Your vehicle may follow the pre-ceding vehicle and also change
lanes.)

WARNING
●When the follow-up cruising dis- play is displayed ( P.248) and the
preceding vehicle is swaying. (Your vehicle may sway accordingly and depart from the lane.)
●When the follow-up cruising dis-play is displayed ( P.248) and the
preceding vehicle departs from its lane. (Your vehicle may follow the preceding vehicle and depart from

●When the follow-up cruising dis-
play is displayed ( P.248) and the preceding vehicle is being driven extremely close to the left/right lane
line. (Your vehicle may follow the preceding vehicle and depart from the lane.)
●Vehicle is being driven around a sharp curve.
●Objects or patterns that could be mistaken for white (yellow) lines are
present on the side of the road (guardrails, reflective poles, etc.).
●Vehicle is driven where the road diverges, merges, etc.
●Repair marks of asphalt, white (yel-
low) lines, etc., are present due to road repair.
●There are shadows on the road that run parallel with, or cover, the white (yellow) lines.
●The vehicle is driven in an area without white (yellow) lines, such as
in front of a tollgate or checkpoint, or at an intersection, etc.
●The white (yellow) lines are cracked, “Raised pavement marker” or stones are present.
●The white (yellow) lines cannot be seen or are difficult to see due to
sand, etc.
●The vehicle is driven on a road sur-
face that is wet due to rain, pud- dles, etc.

■Lane departure alert function
When the system determines that
the vehicle might depart from its
lane*, a warning is displayed on the
multi-information display, and either
a warning buzzer will sound or the
steering wheel will vibrate to alert
the driver.
When the warning buzzer sounds or
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.
Vehicle 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.
*: May recognize the boundaries
between the asphalt and the side of
the road, such as grass, soil, or the
curb, to be road lanes.

●The traffic lines are yellow (which may be more difficult to recognize
than lines that are white).
●The white (yellow) lines cross over
a curb, etc.
●The vehicle is driven on a bright
surface, such as concrete.
●The vehicle is driven on a surface
that is bright due to reflected light, etc.
●The vehicle is driven in an area where the brightness changes sud-denly, such as at the entrances and
exits of tunnels, etc.
●Light from the headlights of an
oncoming vehicle, the sun, etc., enters the camera.
●The vehicle is driven on a slope.
●The vehicle is driven on a road

being dirty or it being misaligned.
●The vehicle is struck by a cross-
wind.
●The vehicle is affected by wind from a vehicle driven in a nearby lane.

■Steering assist function
When the system determines that
the vehicle might depart from its
lane*, the system provides assis-
tance as necessary by operating
the steering wheel in small
amounts for a short period of time
to keep the vehicle in its lane.
Vehicle 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
steering assist function will operate
even if the turn signals are operating.

■Vehicle sway warning function
When the vehicle is swaying within
a lane, the warning buzzer will
sound and a message will be dis-
played on the multi-information dis-
play to alert the driver.
