WARNING
■Handling the radar sensor
Observe the following to ensure the cruise control system can function
effectively.
Otherwise, the system may not function correctly and could result in an
accident.
●Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or
damage them.
●Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may become
inaccurate or malfunction. If the sensor or surrounding area is subject to a
strong impact, always have the area inspected and adjusted by a Toyota
dealer.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor, grille cover or sur-

LDA (Lane Depar ture 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 deviated from its lane. If the system judges that the vehicle
has deviated from its lane, it alerts the driver using a buzzer and indi-
cations on the multi-information display.

■LDA indicator
Even if the LDA switch is pressed, when the LDA indicator does not come on
the system may have a malfunction. Have the vehicle inspected by your Toy-
ota dealer immediately.
■Alert buzzer for lane departure alert
Depending on the audio system sound level or air conditioning fan noise
while the audio system or air conditioning system is in use, it may be difficult
to hear the alert buzzer.
■After the vehicle has been parked in the sun
The LDA may not be available and a warning message will be displayed for a
while after driving has started. When the temperature in the cabin decreases
and the temperature around the camera sensor (P. 227) becomes suitable
for its operation, turn the LDA switch on again after a short time.
■If there are lane markers on only one side of the vehicle
The lane departure alert will not operate for the side on which lane markers
could not be recognized.
■Conditions in which the function may not operate correctly
In the following situations, the camera sensor may be unable to recognize
lane markers causing the lane departure alert function to operate incorrectly.
However, this does not indicate a malfunction.
●When there are shadows on the road running parallel with lane markers, or
if a shadow covers the lane markers
●When driving through an area with no lane markers, such as a toll booth, a
crossing or before a ticket checkpoint
●When the lane markers are broken, Botts’ dots (raised pavement markers)
or stones
●When lane markers are obscured or partially obscured by sand, dirt, etc.
●When driving on a road surface that is wet due to rain, previous rainfall,
standing water, etc.
●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 on a curb, etc.
●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 winding roads or roads that are uneven

4-5. Using the driving support systems
●When driving on rough or unpaved roads
●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 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 changing the tires
Depending on the tires used, such as snow tires, etc., sufficient performance
may not be maintainable.
■Warning messages for the LDA
Warning messages are used to indicate a system malfunction or to inform the
driver of the need for caution while driving. If a warning message is shown on
the multi-information display, read the message and follow the instructions.
Also, even if a warning message is displayed, it will not impede normal driv-
ing.
