ter. (→P.280, 285).
When the temperature around the front
camera is outside of the operational
range, such as when the vehicle is in the
sun or in an extremely cold environment
If the front camera is hot, such as after
the vehicle had been parked in the sun,
use the air conditioning system to
decrease the temperature around the
front camera.
If a sunshade was used when the vehicle
was parked, depending on its type, the
sunlight reflected from the surface of the
sunshade may cause the temperature of
the front camera to become excessively
high.
If the front camera is cold, such after the
vehicle is parked in an extremely cold
environment, use the air conditioning
system to increase the temperature
around the front camera.
The area in front of the front camera is
obstructed, such as when the hood is
open or a sticker is attached to the part of
the windshield in front of the front cam-
era.
Close the hood, remove the sticker, etc.,
to clear the obstruction.

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.
●When not using the LTA system, use the LTA switch to turn the sys-
tem off.
■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 tires of a size other than specified are installed.
●Vehicle is driven in traffic lanes other than that highways and free-
ways.
●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.

WARNING
■When using the Toyota parking
assist-sensor
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 use the sensor at speeds in excess of 10 km/h (6 mph).
●The sensors’ detection areas and reaction times are limited. When moving forward or reversing, check
the areas surrounding the vehicle (especially the sides of the vehicle) for safety, and drive slowly, using
the brake to control the vehicle’s speed.
●Do not install accessories within the sensors’ detection areas.
●The area directly under the bum-pers is not detected.Thin posts or objects lower than the
sensor may not be detected when approached, even if they have been detected before.
■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.
●The vehicle is equipped with a fender pole, wireless antenna or fog
lights.
