COROLLA iM_U (OM12K64U)●In the situations shown below, the system may not be able to accurately
detect surrounding brightness levels. This may cause the low beams to
remain on or the high beams to cause problems for pedestrians, vehicles
ahead or other parties. In these cases, manually switch between the high
and low beams.
• In bad weather (rain, snow, fog, sandstorms, etc.)
• The windshield is obscured by fog, mist, ice, dirt, etc.
• The windshield is cracked or damaged.
• The front sensor is deformed or dirty.
• The front sensor temperature is extremely high.
• Surrounding brightness levels are equal to those of headlights, tail lights
or fog lights.
• Vehicles ahead have headlights or tail lights that are either switched off,
dirty, are changing color, or are not aimed properly.
• When driving through an area of intermittently changing brightness and
darkness.
• When frequently and repeatedly driving ascending/descending roads, or
roads with rough, bumpy or uneven surfaces (such as stone-paved
roads, gravel tracks, etc.).
• When frequently and repeatedly taking curves or driving on a winding
road.
• There is a highly reflective object ahead of the vehicle, such as a sign or
a mirror.
• The back of a vehicle ahead is highly reflective, such as a container on a
truck.
• The vehicle’s headlights are damaged or dirty, or are not aimed properly.
• The vehicle is listing or titling due to a flat tire, a trailer being towed, etc.
• The high beam and low beam are repeatedly being switched between in
an abnormal manner.
• The driver believes that the high beam may be causing problems or dis-
tress to other drivers or pedestrians nearby.

denly, such as at the entrance or exit of a tunnel

WARNING
■Before using the LDA system
Do not rely solely upon the LDA system. LDA is not a system which auto-
matically drives the vehicle or reduces 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 always paying careful attention to the sur-
rounding conditions and operate the steering wheel to correct the path of
the vehicle. Also, make sure to take adequate breaks when fatigued, 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 the LDA by mistake
When not using the LDA system, use the LDA switch to turn the system off.
■Preventing LDA system malfunctions and operations performed by
mistake
●Do not modify the headlights or place stickers, etc., on the surface of the
lights.
●Do not modify the suspension etc. If the suspension etc. needs to be
replaced, contact your Toyota dealer.
●Do not install or place anything on the hood or grille. Also, do not install a
grille guard (bull bars, kangaroo bar, etc.).
●If your windshield needs repairs, contact your Toyota dealer.

and various functions may not operate normally.
●There are shadows on the road that run parallel with, or cover, the white
(yellow) lines.
●The vehicle is driven in an area without white (yellow) lines, such as in front
of a tollgate or checkpoint, or at an intersection, etc.
●The white (yellow) lines are cracked, or cat's eyes (reflective markers) or
stones are present.
●The white (yellow) lines cannot be seen or are difficult to see due to sand,
etc.
●The vehicle is driven on a road surface that is wet due to rain, puddles, etc.
●The traffic lines are yellow (which may be more difficult to recognize than
lines that are white).
●The white (yellow) lines cross over a curb, etc.
●The vehicle is driven on a bright surface, such as concrete.
●The vehicle is driven on a surface that is bright due to reflected light, etc.
●The vehicle is driven in an area where the brightness changes suddenly,
such as at the entrances and exits of tunnels, etc.
●Light from the headlights of an oncoming vehicle, the sun, etc., enters the
camera.
●The vehicle is driven where the road diverges, merges, etc.
●The vehicle is driven on a slope.
●The vehicle is driven on a road which tilts left or right, or a winding road.
●The vehicle is driven on an unpaved or rough road.
●The vehicle is driven around a sharp curve.
●The traffic lane is excessively narrow or wide.
●The vehicle is extremely tilted due to carrying heavy luggage or having
improper tire pressure.
●The distance to the preceding vehicle is extremely short.
●The vehicle is moving up and down a large amount due to road conditions
during driving (poor roads or road seams).
