■Changing the pre-collision
warning timing
The pre-collision warning timing
can be changed on ( P.494) of
the multi-information display.
The warning timing setting is retained
when the power switch is turned off.
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-
gency steering assist timing will
also be changed accordingly.
If late is selected, emergency steer-
ing assist would not operate in case
of an emergency.

extremely hot, or wet • If the vehicle is not properly main-tained (brakes or tires are excessively
worn, improper tire inflation pressure, etc.)• When the vehicle is being driven on a

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.)

■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.
WARNING
●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
which tilts left or right, or a winding road.
●The vehicle is driven on an unpaved or rough road.
●The traffic lane is excessively nar-row or wide.
●The vehicle is extremely tilted due to carrying heavy luggage or having improper tire pressure.
●The distance to the preceding vehi-cle is extremely short.
●The vehicle is moving up and down a large amount due to road condi-
tions during driving (poor roads or road seams).
●When driving in a tunnel or at night with the headlights off or when a headlight is dim due to its lens
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.
●The vehicle has just changed lanes or crossed an intersection.
●Tires which differ by structure, man-ufacturer, brand or tread pattern are used.
●When tires of a size other than specified are installed.
●Snow tires, etc., are equipped.
●The vehicle is being driven at extremely high speeds.

Toyota parking assist-sensor OFF
indicator ( P.92) illuminates.
To re-enable the system when it
was disabled, select on the
multi-information display, select

WARNING
■Cautions regarding the use of
the system
There is a limit to the degree of recog- nition accuracy and control perfor-
mance that this system can provide, do not overly rely on this system. The driver is always responsible for paying
attention to the vehicle’s surroundings and driving safely.
■To ensure the system can oper-ate properly
Observe the following precautions.
Failing to do so may result in the vehi- cle being unable to be driven safely and possibly cause an accident.
●Do not damage the sensors, and always keep them clean.
●Do not attach a sticker or install an electronic component, such as a
backlit license plate (especially fluo- rescent type), fog lights, fender pole or wireless antenna near a radar
sensor.
●Do not subject the surrounding area of the sensor to a strong impact. If subjected to an impact, have the
vehicle inspected by your any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer. If the front or rear bumper needs to be removed/installed or replaced, contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Do n ot m od i fy, d is a sse mb l e o r p ai n t the sensors.
●Do not attach a license plate cover.
●Keep your tires properly inflated.
■When to disable the function
In the following situations, disable the
function as it may operate even though there is no possibility of a colli-sion.
●Failing to observe the warnings above.
●A non-genuine Toyota suspension (lowered suspension, etc.) is
installed.
■Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor
malfunctioning.
●When using a high pressure
washer to wash the vehicle, do not spray the sensors directly, as doing so may cause a sensor to malfunc-
tion.
●When using steam to clean the
vehicle, do not direct steam too close to the sensors as doing so may cause a sensor to malfunction.
