■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 guar d (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.

attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that 
absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections pro-
jecting outwards in the direction of  your vehicle 
People may not be detected if they are  
wearing certain types of clothing.
■Situations in which the system may  not operate properly 
Certain vehicle conditions and the sur- 
rounding environment may affect the  ability of a sensor to correctly detect  
objects. Particular instances where this 
may occur are listed below.
●There is dirt, snow or ice on a sensor. 
(Cleaning the sensors will resolve this  problem.)
●A sensor is frozen. (Thawing the area will resolve this problem.)  
In especially cold weather, if a sensor 
is frozen the sensor display may be  displayed abnormally, or objects, such  
as a wall, may not be detected.
●A sensor is covered in any way.
●When a sensor or the area around a  sensor is extremely hot or cold.
●On an extremely bumpy road, on an  
incline, on gravel, or on grass.
●When vehicle horns, vehicle detec-
tors, motorcycle engines, air brakes of  large vehicles, the clearance sonar of  
other vehicles or other devices which 
produce ultrasonic waves are near the  
vehicle
●A sensor is coated with a sheet of  
spray or heavy rain.
●If objects draw too close to the sensor.
●When a pedestrian is wearing clothing  that does not reflect ultrasonic waves  
(ex. skirts with ga thers or frills).
●When objects that are not perpendicu- 
lar to the ground, not perpendicular to 
the vehicle traveling direction, une- ven, or waving are in the detection  
range.
●Strong wind is blowing
●When driving in inclement weather  such as fog, snow or a sandstorm
●When an object that cannot be detected is between the vehicle and a  
detected object
●If an object such as a vehicle, motor-
cycle, bicycle or pedestrian cuts in 
front of the vehicle or runs out from  the side of the vehicle
●If the orientation of a sensor has been changed due to a collision or other  
impact
●When equipment that may obstruct a 
sensor is installed, such as a towing 
eyelet, bumper protector (an addi- tional trim strip, et c.), bicycle carrier,or  
snow plow
●If the front of the vehicle is raised or 
lowered due to the carried load
●If the vehicle cannot be driven in a 
stable manner, such as when the 
vehicle has been in an accident or is  malfunctioning
●When a tire chains, compact spare tire or an emergency tire puncture repair  
kit is used
■Situations in which the system may 
operate even if there is no possibil-
ity of a collision 
In some situations, such as the follow- 
ing, the system may operate even 
though there is no possibility of a colli- sion.

■Cautions regarding the use of  
the system 
Do not overly rely on the system, as  
doing so may lead to an accident.
●The driver is solely responsible for  safe driving. Always drive carefully,  
taking care to observe your 
surroundings. The Parking Support  Brake system is designed to pro- 
vide support to lessen the severity 
of collisions. However, it may not  operate in some situations.
●The Parking Support Brake system is not designed to stop the vehicle  
completely. Additionally, even if the 
system has stopped the vehicle, it  is necessary to depress the brake  
pedal immediately as brake control 
will be canceled after approximately  2 seconds.
●It is extremely dangerous to check the system operatio ns by intention- 
ally driving the vehicle into the 
direction of a wall, etc. Never  attempt such actions.
■When to disable the Parking Sup-port Brake 
In the following situations, disable the  
Parking Support Br ake as the system  may operate even though there is no  
possibility of a collision.
●When inspecting the vehicle using 
a chassis roller, chassis dynamo or 
free roller
●When loading the vehicle onto a 
boat, truck or other transport vessel
●If the suspension has been modi-
fied or tires of a size other than  specified are installed
●If the front of the vehicle is raised or lowered due to the carried load
●When equipment that may obstruct a sensor is installed, such as a tow- 
ing eyelet, bumper protector (an 
additional trim strip, etc.), bicycle  carrier, or snow plow
●When using automatic car washing devices
●If the vehicle cannot be driven in a stable manner, such as when the  
vehicle has been in an accident or 
is malfunctioning
●When the vehicle is driven in a 
sporty manner or off-road
●When the tires are not properly 
inflated
●When the tires are very worn
●When a tire chains, compact spare 
tire or an emergency tire puncture 
repair kit is used

As with unequipped vehicles, move 
forward and back up carefully while  directly confirming the safety of  
your surroundings and the area to 
the rear of the vehicle.
●Do not back up while viewing the 
multi-information display. Backing 
up while only viewing the monitor  screen may cause a collision or  
lead to an accident, as the image 
displayed on the monitor screen  may differ from actual conditions.  
Make sure to visually check the sur-
rounding areas and the area to the  rear of the vehicle with and without  
the mirror while backing up.
●Drive slowly while adjusting your 
speed by depressing the brake 
pedal when backing up or moving  forward.
●If it seems the vehicle may make contact with a pedestrian, another  
vehicle or any other obstacles, stop 
the vehicle by depressing the brake  pedal, and then press the S-IPA  
switch to turn off the system.
●Use the system in a parking lot with 
a flat surface.
●Observe the following precautions, 
as the steering wheel automatically 
turns during use. 
• There is risk of a necktie, scarf,  
your arm, etc. being caught on the 
steering wheel. Please do not allow  your upper body to be close to the  
steering wheel. Also, do not allow 
children close to the steering wheel. 
• There is a possibility of injury when  
the steering wheel turns if you have  long fingernails.
• In case of emergency, stop the vehicle by depressing the brake  
pedal, and then press the S-IPA 
switch to turn off the system.
●Always confirm that there is appro-
priate space before attempting to  park the vehicle and operate the  
system.
●Do not use the system in the follow-
ing situations, as the system may 
be unable to correctly assist you in  reaching the target parking spot  
and may lead to an unexpected 
accident. 
• In an area that is not a parking lot 
• A parking lot that is not paved and  has no parking space lines, such as  
a sand or gravel parking lot 
• A parking lot that has a slope or  
undulations in the road 
• A frozen, snow-covered or slippery  
road 
• The asphalt is melting due to hot  
weather 
• There is an obstacle between the  
vehicle and the target parking spot 
• Using tire chains or compact spare  
tire (if equipped)
●Do not use tire other than that pro-
vided by the manufacturer. The sys-
tem may not operate properly.  When replacing tires, contact any  
authorized Toyota retailer or Toyota 
authorized repairer, or any reliable  repairer.
●The system may not be able to  
position the vehicle in the set loca- tion in the following situations. 
• The tires are extremely worn or the  
tire pressure is low 
• The vehicle is carrying very heavy  
load
