■ Trailer towing precautions
When towing, make sure that none of the weight limits are exceeded.
( P. 2 3 4 )
■ To avoid accident or injury
● Vehicles with a compact spare tire:
Do not tow a trailer when the compact spare tire is installed on your vehi-
cle.
● Vehicles with the emergency tire puncture repair kit:
Do not tow a trailer when the tire installed is repaired with the emergency
tire puncture repair kit.
● Do not use cruise control or dynamic radar cruise control with full-speed
range when trailer towing. (if equipped)
■ Vehicle speed in towing
Observe the legal maximum speeds for trailer towing.
■ Before descending hills or long declines
Reduce speed and downshift. However, never downshift suddenly while
descending steep or long downhill grades.
■ Operation of the brake pedal

WARNING
■Before using LTA system
● Do not rely solely upon the LTA system. The LTA system does not auto-
matically 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 surround-
ing conditions and operating the steering wheel to correct 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 driving 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 system off.
■ Situations 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 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-covered 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 construction
work.
● Vehicle is driven in a construction zone.
● A spare tire, tire chains, etc. are equipped.
● When the tires have been excessively worn, or when the tire inflation pres-
sure is low.
● During emergency towing.
■ Preventing LTA system malfunctions 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, kangaroo bar, etc.).
● If your windshield needs repairs, contact any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.

● 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 additional trim strip, etc.), 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 tire chains, a compact spare tire or an emergency tire puncture repair
kit are used.
■ Situations in which the system may operate even if there is no possibil-
ity of a collision
In some situations, such as the following, the system may operate even
though there is no possibility of a collision.
● When driving toward a banner, flag, low-hanging branch or boom barrier
(such as those used at railroad crossings, toll gates and parking lots)
● When there is a rut or hole in the surface of the road
● When driving on a metal cover (grating), such as those used for drainage
ditches
● When driving up or down a steep slope
● If a sensor is hit by a large amount of water, such as when driving on a
flooded road
● There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors
will resolve this problem.)
● A sensor is coated with a sheet of spray or heavy rain
● When driving in inclement weather such as fog, snow or a sandstorm
● When driving on a narrow road
● When strong winds are blowing

■When to disable the Parking Support Brake
In the following situations, disable the Parking Support Brake 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 modified or tires of a size other than specified
are installed

● When tire chains, compact spare tire or an emergency tire puncture repair
kit are used
■ To ensure the system can operate properly
 P. 3 9 2
■ Handling the suspension
Do not modify the suspension, as changes to the height or incline of the
vehicle may prevent the sensors from correctly detecting obstacles, may
cause the system not operate, or may cause the system to operate unnec-
essarily.
■ If the Parking Support Brake function (static objects) operates unnec-
essarily, such as at a railroad crossing

WARNING
●Do not use the system in the following 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 provided by the manufacturer. The system
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 position the vehicle in the set location in the
following situations.
• The tires are extremely worn or the tire pressure is low
• The vehicle is carrying very heavy load
• The vehicle is tilted due to having luggage, etc. located on one side of
the vehicle
• There are road heaters installed in the parking lot to prevent the road
surface from freezing.
In any other situations when the set position and vehicle position greatly
differ, have the vehicle inspected by any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
● Make sure to observe the following precautions regarding the exit parallel
parking assist mode.
Exit parallel parking assist mode is a function used when departing from a
parallel parking spot. However, this function may not be usable if obsta-
cles or people are detected in front of the vehicle. Only use this function
when departing from a parallel parking s pot. In the event that the steering
control operates, either turn the system off using the S-IPA switch or oper-
ate the steering wheel to stop the control.
● If exit parallel parking assist mode is mistakenly used in the following situ-
ations, the vehicle may make contact with an obstacle.
The departure function is operated in a direction where an obstacle is
present, but the obstacle is not detected by the side sensors (situations
such as when the vehicle is directly beside a pole).
