QConditions in which the light distribution control of the headlights
changes automatically
OWhen all of the following conditions are met, the high beams will be turned
on automatically and the system will operate:
• The vehicle speed is approximately 60 km/h (37 mph) or more.
*
*
: The area in the direction that the vehicle is turning will be illuminated more
brightly than other areas while driving on a curve.
OWhen all of the following conditions are met, the variable high beams will
turn on and the distance that the low beams are projected will be adjusted
automatically, depending on the location of vehicles ahead:
• The vehicle speed is approximately 60 km/h (37 mph) or more.
• There are vehicles ahead with headlights or tail lights turned on.
• The area ahead of the vehicle is dark.
OIf any of the following conditions is met, the high beams or variable high
beams will be changed to the low beams automatically:
• The vehicle speed is below approximately 40 km/h (25 mph).
• The area ahead of the vehicle is not dark.
• There are many vehicles ahead.
• Vehicles ahead are moving quickly and the high beams may blind the
drivers of the other vehicles.
QFront camera detection information
OThe high beams may not be automatically changed to the variable high
beams in the following situations:
• When vehicles ahead suddenly appear from a curve
• When the vehicle is cut in front of by another vehicle
• When vehicles ahead are hidden from sight due to repeated curves, road
dividers or roadside trees
• When vehicles ahead appear from the faraway lane on wide road
• When vehicles ahead have no lights
OThe high beams may be changed to the variable high beams if a vehicle
ahead that is using fog lights without its headlights turned on is detected.
OHouse lights, street lights, traffic signals, and illuminated billboards or signs
may cause the high beams to change to the variable high beams, cause the
high beams not to change to the variable high beams, or change the area
that is not illuminated.

Driving
OThe following factors may affect the amount of time taken to turn the high
beam on or off, or the speed by which the areas not illuminated change:
• The brightness of headlights, fog lights, and tail lights of vehicles ahead
• The movement and direction of vehicles ahead
• When a vehicle ahead only has operational lights on one side
• When a vehicle ahead is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of the road surface
etc.)
• The number of passengers and amount of luggage
OThe light distribution control of the headlights may change unexpectedly.
OBicycles or similar objects may not be detected.
OIn 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 camera is deformed or dirty.
• The front camera temperature is extremely high.
• Surrounding brightness levels are equal to those of headlights, tail lights
or fog lights.
• Vehicles ahead have headlights that are either switched off, dirty, are
changing color, or are not aimed properly.
• The vehicle is hit by water, snow, dust, etc. from a preceding vehicle.
• 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.
• The vehicle is listing or tilting, 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.

WARNING
QTo avoid malfunction of the front camera
Observe the following precautions.
Otherwise, the front camera may not operate properly, possibly leading to
an accident resulting in death or serious injury.
O Keep the windshield clean at all times.
• If the windshield is dirty or covered with an oily film, water droplets,
snow, etc., clean the windshield.
• If a glass coating agent is applied to the windshield, it will still be neces-
sary to use the windshield wipers to remove water droplets, etc . from
the area of the windshield in front of the front camera.
• If the inner side of the windshield where the front camera is installed is
dirty, contact any authorized Toyota retailer or Toyota authori zed
repairer, or any reliable repairer.
O If the part of the windshield in front of the front camera is fogged up or cov-
ered with condensation, or ice, use the windshield defogger to remove the
fog, condensation, or ice. ( P. 527)
O If water droplets cannot be properly removed from the area of the wind-
shield in front of the front camera by the windshield wipers, r eplace the
wiper insert or wiper blade.
O Do not attach window tint to the windshield.
O Replace the windshield if it is damaged or cracked.

Prius Plug-in Hybrid_OM_OM47E75E_(EE)QIf a warning message is displayed on the multi-information display
A system may be temporarily unavailable or there may be a malfunction in
the system.
OIn the following situations, perform the actions specified in the table. When
the normal operating conditions are detected, the message will disappear
and the system will become operational.
If the message does not disappear, contact any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
SituationActions
When the area around a cam-
era is covered with dirt, mois-
ture (fogged up, covered with
condensation, ice, etc.), or
other foreign matter
Using the wiper and A/C function,
remove the dirt and other attached mat-
ter. (P. 527)
When the temperature around
the front camera is outside of
the operational range, such as
when the vehicle is in the sun or
in an extremely cold environ-
ment
If the front camera is hot, such as after
the vehicle had been parked in the sun,
use the air conditioning system to
decrease the temperature around the
front camera.
If a sunshade was used when the vehi-
cle was parked, depending on its type,
the sunlight reflected from the surface
of the sunshade may cause the tem-
perature of the front camera to become
excessively high.
If the front camera is cold, such after the
vehicle is parked in an extremely cold
environment, use the air conditioning
system to increase the temperature
around the front camera.
The area in front of the front
camera is obstructed, such as
when the hood is open or a
sticker is attached to the part of
the windshield in front of the
front camera.
Close the hood, remove the sticker, etc.
to clear the obstruction.
When “Pre-Collision System
Unavailable” is displayed.Check whether there is attached materi-
als on the radar sensor and radar sensor
cover, and if there is, remove it.

Driving
OIn the following situations, if the situation has changed (or the vehicle has
been driven for some time) and the normal operating conditions are
detected, the message will disappear and the system will become opera-
tional.
If the message does not disappear, contact any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
• When the temperature around the radar sensor is outside of the opera-
tional range, such as when the vehicle is in the sun or in an extremely
cold environment
• When the front camera cannot detect objects in front of the vehicle, such
as when driving in the dark, snow, or fog, or when bright lights are shining
into the front camera
• Depending on the conditions in the vicinity of the vehicle, the radar may
judge the surrounding environment can not be properly recognized. In
that case, “Pre-Collision System Unavailable” is displayed.

may lead to an accident, resulting in death or serious injury.
O When not using the LTA system, use the LTA switch to turn the system off.
