■ If the PCS warning light flashes or illuminates
The pre-crash safety system may be temporarily unavailable or there may be
a malfunction in the system.
● In the following situations, the warning light will be cleared and the system
will become operational when normal operating conditions return:

LDA (Lane Departure Alert)
While driving on a road that has lane markers, this system recognizes
the lane markers using a camera as a sensor to alert the driver when
the vehicle deviates from its lane.
If the system judges that the vehicle has deviated from its lane, it
alerts the driver using a buzzer and indications on the meter.
Front sensor
Press the LDA switch to activate
the system.
The LDA indicator will come on.
Press the switch again to turn the
LDA system off.
The LDA system will remain on or
off even if the engine switch is
turned off.
● When the vehicle speed is approximately 50 km/h (32 mph) or
more
● When the lane width is more than approximately 3 m (9.8 ft.)
● When driving on a straight road or through a curve with a radius of
more than approximately 150 m (492 ft.)

When both of the lane marker
indicators turn green:
Indicates that both right and left
lane markers are recognized.
If the vehicle deviates from the
lane, the lane marker indicators of
the deviated side will flash yellow.
When either of the lane marker
indicators turns green:
Indicates that the lane marker on
the green-marked side is recog-
nized.
If the vehicle deviates from a lane
on the side with the recognized
lane markers, the lane marker indi-
cators will flash in yellow.
When both of the lane marker
indicators turn off:

■Temporary cancelation of the LDA system functions
If any of the following occurs, the LDA system functions will be temporarily
canceled. The functions will resume after the necessary operating conditions
have returned.
● The turn signal lever is operated.
● The vehicle speed deviates from the operating range of the LDA system
functions.
● When the lane lines cannot be recognized while driving.
● When the lane departure warning sounds.
The lane departure warning function will not operate again for a several sec-
onds after it has been activated, even if the vehicle leaves the lane again.
■ The lane departure warning
Depending on the audio system sound level or air conditioning fan noise
while the audio system or air conditioning sy stem is in use, it may be difficult
to hear the warning sound.
■ After the vehicle has been parked in the sun
The LDA system may not be immediately available. When the temperature in
the cabin decreases and the temperature around the front sensor ( P. 188)
becomes suitable for its operation, the functions will begin to operate.
■ If there are lane markers on only one side of the vehicle
The lane departure warning will not oper ate for the side on which lane mark-
ers could not be recognized.

■ Conditions in which the function may not operate correctly
In the following situations, the front sensor may be unable to recognize lane
markers causing the lane departure warning function to operate incorrectly.
However, this does not indicate a malfunction.
● When driving through an area, such as a tollbooth, a crossing or before a
ticket checkpoint
● When driving on a sharp curve
● When lane markers are extremely narrow or extremely wide
● When the vehicle leans to one side an unusual amount due to a heavy load
or improper tire inflation pressure
● When the following distance between your vehicle and the vehicle ahead is
extremely short
● When the lane markers are yellow (These may be more difficult for the sys-
tem to recognize compared to white markers.)
● When the lane markers are broken, Botts’ dots (raised pavement markers)
or stones
● When the lane markers are on a curb etc.
● When lane markers are obscured or partially obscured by sand, dirt, etc.
● When there are shadows on the road running parallel with lane markers, or
if a shadow covers the lane markers
● When driving on a particularly bright road surface, such as concrete
● When driving on a road surface that is bright due to reflected light
● When driving in a location where the light level changes rapidly, such as the
entrance to or exit from a tunnel
● When sunlight or the headlights of oncoming vehicles are shining directly
into the camera lens
● When driving on roads that are branching or merging
● When driving on a road surface that is wet due to rain, previous rainfall,
standing water, etc.
● When the vehicle experiences strong up-and-down motion such as when
driving on an extremely rough road or on a seam in the pavement
● When headlight brightness at nighttime is reduced due to dirt on the lenses,
or when the headlights are misaligned
● When driving on winding roads or roads that are uneven
● When driving on rough or unpaved roads
● When the windshield is dirty, or if raindrops, condensation or ice are adher-
ing to the windshield
● When the heater is blowing to the feet, the upper part of the windshield may
get fogged up and have a negative effect
● When cleaning the inside of the windshield, touching the lens or getting
glass cleaner on the lens may have a negative effect

■ When changing the tires
Depending on the tires used, sufficient performance may not be maintainable.
■ If the LDA indicator comes on in yellow
It may indicate a malfunction in the system. Contact any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
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 operati ng 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
