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.

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.

Prius Plug-in Hybrid_OM_OM47D72E_(EE)
WARNING
■Caution regarding the use of windshield wipers in AUTO mode
The windshield wipers may operate unexpectedly if the sensor is touched or
the windshield is subject to vibration in AUTO mode. Take care that your fin-
gers etc. do not become caught in the windshield wipers.
■ Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.
NOTICE
■ When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■ When the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may over-
heat.
■ When a nozzle becomes blocked
In this case, contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.

Prius Plug-in Hybrid_OM_OM47D72E_(EE)
WARNING
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do
so may result in death or serious injury.
● After exiting the vehicle and before opening the fuel door, touch an
unpainted metal surface to discharge any stat ic electricity. It is important to
discharge static electricity before re fueling because sparks resulting from
static electricity can cause fuel vapors to ignite while refueling.
● Always hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out of the filler neck and cause injury.
● Do not allow anyone that has not discharged static electricity from their
body to come close to an open fuel tank.
● Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
● Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
● Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition
hazard.
■ When refueling
Observe the following precautions to pr event fuel overflowing from the fuel
tank:
● Securely insert the fuel nozzle into the fuel filler neck.
● Stop filling the tank after the fuel nozzle automatically clicks off.
● Do not top off the fuel tank.
NOTICE
■Refueling
Do not spill fuel during refueling.
Doing so may damage the vehicle, such as causing the emission control
system to operate abnormally or damaging fuel system components or the
vehicle’s painted surface.
