disappear and the system will become operational when normal operating
conditions return:
• When the area around the front sensor is hot, such as in the sun
• When the windshield is fogged up or covered with condensation or ice
(→P. 199)
• When the front sensor or the area around either sensor is cold, such as in
an extremely cold environment
• If the area in front of the front sensor is obstructed, such as when the
hood is open
●If the PCS warning light continues to flash or illuminate or the warning mes-
sage does not disappear, the system may be malfunctioning. Have the vehi-
cle inspected by your Toyota dealer immediately.

1764-5. Using the driving support systems
COROLLA iM_U (OM12K64U)
When driving on roads with white (yellow) lines, this function alerts the
driver when the vehicle might depart from its lane.
The LDA system recognizes visi-
ble white (yellow) lines with the
front sensor on the upper portion
of the front windshield.
When the system determines that
the vehicle might depart from its
lane, a warning is displayed on
the multi-information display and
the warning buzzer sounds to
alert the driver.
When the warning buzzer sounds,
check the surrounding road situa-
tion and carefully operate the
steering wheel to move the vehicle
back to the center within the white
(yellow) lines.
