3885-3. Operating the lights and wipers
Prius Plug-in Hybrid_OM_OM47D72E_(EE)
This system allows the headlights and front position lights to be turned
on for 30 seconds when the power switch is off.
Pull the lever toward you and
release it with the light switch is in
the position after turning
the power switch off.
Pull the lever toward you and
release it again to turn off the
lights.
■ Daytime running light system
To make your vehicle more visible to other drivers during daytime driving, the
daytime running lights turn on automatically whenever the hybrid system is
started and the parking brake is released with the headlight switch in the
position. Daytime running lights are not designed for use at night.
■ Headlight control sensor
Follow me home system
IO53PH031
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the
windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.
Air conditioning operation may also be interrupted.

Driving
AHS (Adaptive High-beam System)
● Adjusts the brightness and illuminated area of the high beams
according to the vehicle speed.
● Operates the variable high
beams so that the area around
vehicles ahead is partially not
illuminated while all other areas
continue to be illuminated with
the high beams.
The variable high beams help opti-
mize forward visibility while reduc-
ing the dazzling effect on the
drivers of vehicles ahead.
● Adjusts the intensity of the high beams, while driving on a curve, so
that the area in the direction that the vehicle is turning will be illumi-
nated more brightly than other areas.
● Adjusts the distance that the low beams are projected according to
the distance to a preceding vehicle.
The Adaptive High-beam System uses a front camera located
behind the upper portion of the windshield to assess the bright-
ness of the lights of vehicles ahead, streetlights, etc., and auto-
matically controls the headlight light distribution as necessary.
Illuminated area of the high beams
Illuminated area of the low beams
WARNING
■ Limitations of the Adaptive High-beam System
Do not rely on the Adaptive High-beam System. Always drive safely, taking
care to observe your surroundings and turning the high beam on or off man-
ually if necessary.
■ To prevent incorrect operation of the Adaptive High-beam system
Do not overload the vehicle.

Driving
●The 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
●The light distribution control of the headlights may change unexpectedly.
●Bicycles or similar objects may not be detected.
●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 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.

Washer/wiper dual
operation
Pulling the lever operates the wip-
ers and washer.
The wipers will automatically oper-
ate a couple of times after the
washer squirts.
■ The windshield wipers and washer can be operated when
The power switch is in ON mode.
■ Dripping prevention wiper sweep
After washing and wiping operation se veral times, the wipers operate one
more time after a short delay to prevent dripping. However, this function will
not operate while driving.
■ Raindrop sensor
● If the wiper switch is turned to the position while the power switch is in
ON mode, the wipers will operate once to show that AUTO mode is acti-
vated.
● If the wiper sensitivity is adjusted to higher, the wiper may operate once to
indicate the change of sensitivity.
● If the temperature of the raindrop sensor is 85C (185F) or higher, or -15C
(5°F) or lower, automatic operation may not occur. In this case, operate the
wipers in any mode other than AUTO mode.
■ If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the
washer fluid tank.
■ Customization
Settings of AUTO mode operation can be changed. (Customizable features:

●The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs etc. are
present on the windshield.IO53PH040
