In the following situations, disable the system, as it may not operate prop-
erly, possibly leading to an accident resulting in death or serious injury:
● When the vehicle is being towed
● When your vehicle is towing another vehicle
● When transporting the vehicle via truck, boat, train or similar means of
transportation
● When the vehicle is raised on a lift with the hybrid system on and the tires

mometer or speedometer tester, or when using an on vehicle whee l bal-
ancer
● When a strong impact is applied to the front bumper or front gr ille, due to
an accident or other reasons

● When the tires are not properly inflated
● When the tires are very worn
● When tires of a size other than specified are installed

Driving
WARNING
■Before using LDA system
Do not rely solely upon the LDA system. The LDA 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 fatigu ed, 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.
■ To avoid operating LDA system by mistake
When not using the LDA system, use the LDA switch to turn the system off.
■ Situations unsuitable for LDA system
Do not use the LDA system in the following situations.
The system may not operate properly and lead to an accident, re sulting in
death or serious injury.
● A spare tire, tire chains, etc. are equipped.
● When the tires have been excessively worn, or when the tire inf lation pres-
sure is low.
● Tires which differ by structure, manufacturer, brand or tread p attern are
used.
● Objects or patterns that could be mistaken for white (yellow) l ines are
present on the side of the road (guardrails, curbs, reflective poles, etc.).
● Vehicle is driven on a snow-covered road.
● White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.
● Asphalt repair marks, white (yellow) line marks, etc. are prese nt due to
road repair.
● Vehicle is driven in a temporary lane or restricted lane due to construction
work.
● Vehicle is driven on a road surface which is slippery due to rainy weather,
fallen snow, freezing, etc.
● Vehicle is driven in traffic lanes other than on highways and freeways.
● Vehicle is driven in a construction zone.

4-5. Using the driving support systems
WARNING
●Do not use the system in the following situations, as the syste m may be
unable to correctly assist you in reaching the target parking s pot 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. T he system
may not operate properly. When replacing tires, contact your Toyota
dealer.
● 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 your Toyota dealer.
● Make sure to observe the following precautions regarding the exit parallel
parking assist mode.
Exit parallel parking assist mode is a function used when depar ting 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 spot. In the event that the steering
control operates, either turn the system off using the S-APGS s witch or
operate 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).

WARNING
●Do not place anything on the luggage cover. In the event of sud den brak-
ing or turning, the item may go flying and strike an occupant. This could
lead to an unexpected accident, resulting in death or serious i njury.
● Do not allow children to climb on the luggage cover. Climbing on the lug-
gage cover could result in damage to the luggage cover, possibl y causing
death or serious injury to the child.
● Make sure that the rear edge of the cover is laying flat. If th e cover is
installed with the rear edge raised, the view from the rear win dow may be
obstructed, which could cause an accident.
● Make sure that seat belts are not caught up in the luggage cover. If a seat
belt is caught up in the cover, it may not be able to restrain passengers
properly.

Tires
Check if the treadwear indicators are showing on the tires. Also check
the tires for uneven wear, such as excessive wear on one side o f the
tread.
Check the spare tire (if equipped) condition and pressure if no t
rotated.
New tread
Worn tread
Treadwear indicator
The location of treadwear indicators is shown by a “TWI” or “ ” mark,
etc., molded into the s idewall of each tire.
Replace the tires if the treadwear indicators are showing on a tire.
Replace or rotate tires in accordance with maintenance sched-

6-3. Do-it-yourself maintenance
Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valves and transmitters to detect low tire infla-
tion pressure before serious problems arise.
If the tire pressure drops below a predetermined level, the dri ver is
warned by a warning light. ( P. 583)
The compact spare tire is not equipped with a tire pressure warning
valve and transmitter.
◆Installing tire pressure warn ing valves and transmitters
When replacing tires or wheels, tire pressure warning valves an d
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new ID codes must be registered in the tire pressure
warning computer and the tire pressure warning system must be
initialized. Have tire pressure warning valve and transmitter I D
codes registered by your Toyota dealer. ( P. 523)
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized when the
tire inflation pressu re is changed such a s when changing trav-
elling speed or load weight.
When the tire pressure warning sy stem is initialized, the current tire
inflation pressure is set as the benchmark pressure.
