the entrance of a curve
When passing an oncoming vehicle on a curve
When passing an oncoming vehicle while making a left or right turn

When rapidly closing on an electric toll gate barrier, parking area barrier,
or other barrier that opens and closes
When approaching an overpass, traffic sign, billboard, etc.
When the front part of the vehicle is raised or lowered
When the sensor is misaligned due to a strong impact being applied to
the sensor, etc.
When there is a structural object (billboard, street light, etc.) at the top of
an uphill road
When there is a metal object (manhole cover, steel plate, etc.) at the bot-

has been parked in the sun
• When the windshield is fogged up or covered with condensation or ice
( P. 288)
• If the area in front of the front sens or is obstructed, such as when the
hood is open
● If the PCS warning light continues to flash, the system may be malfunction-
ing. Have the vehicle inspected by any authorized Toyota dealer or repairer,

WARNING
■Before using the LDA system
Do not rely solely on the LDA system. The LDA system does not drive the
vehicle automatically, nor does it reduce the amount of care you need to
take. As such, the driver must always assume full responsibility for under-
standing his/her surroundings, for operat ing the steering wheel to correct
the driving line, and for driving safely.
Inappropriate or negligent driving could lead to an accident.
■ To avoid operating the LDA by mistake
Switch the LDA system off using the LDA switch when not in use.
■ Situations unsuitable for LDA system
Do not use the LDA system in any of the following situations.
Otherwise, the system may not function correctly and could result in an
accident.
● When driving with tire chains, a spare tire, or similar equipment
● When there are objects or structures along the roadside that might be mis-
interpreted as lane markers (such as guardrails, a curb, reflector posts,
etc.)
● When driving on snowy roads
● When pavement lane markers are difficult to see due to rain, snow, fog,
sand, dirt, etc.
● When there are visible lines on the pavement from road repairs, or if the
remains of old lane markers are still visible on the road
● When driving on a road with lane closures due to maintenance, or when
driving in a temporary lane
NOTICE
■ To prevent damage to or incorrect operation of the LDA system
● Do not modify the headlights or attach stickers to the surface of the lights.
● Do not modify the suspension. If your suspension needs repairs, contact
any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional.
● Do not install or place anything on the hood or the grille. Also, do not install
a grille guard (bull bars, kangaroo bar etc.).
