Prius Plug-in Hybrid_OM_OM47E75E_(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 in
the position after turning
the power switch off.
Pull the lever toward you and
release it again to turn off the
lights.
Q Daytime running light system
To make your vehicle more visible to other drivers during dayti me driving, the
daytime running lights turn on automatically whenever the hybri d system is
started and the parking brake is released with the headlight sw itch in the
position. Daytime running lights are not designed for use at n ight.
Q Headlight control sensor
Extended Headlight Lighting 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.

After washing and wiping operati on several times, the wipers operate one
more time after a short delay to prevent dripping. However, thi s function will
not operate while driving.
Q Raindrop sensor
O 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.
O If the wiper sensitivity is adjusted to higher, the wiper may operate once to
indicate the change of sensitivity.
O 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.

WARNING
QCaution regarding the use of windshield wipers in AUTO mode
The windshield wipers may operate unexpectedly if the sensor is touched or

• If your vehicle is skidding
• If the wheels are misaligned
• If a wiper blade is blocking the front camera
• The vehicle is being driven at extremely high speeds
• When driving on a hill
• If the radar sensor or front camera is misaligned
OIn some situations such as the following, sufficient braking force may not be
obtained, preventing the system from performing properly:
• If the braking functions cannot operate to their full extent, such as when
the brake parts are extremely cold, extremely hot, or wet
• If the vehicle is not properly maintained (brakes or tires are excessively
worn, improper tire inflation pressure, etc.)
• When the vehicle is being driven on a gravel road or other slippery sur-
face
QIf VSC is disabled
OIf VSC is disabled (P. 511), the pre-collision brake assist and pre-collision
braking functions are also disabled.
OThe PCS warning light will turn on and “VSC Turned Off Pre-Collision Brake

WARNING
OObserve the following precautions, as the sensors may stop functioning
properly which may lead to an accident.
• Do not subject the sensor to strong shocks by hitting it, etc. The sen-
sors may not function properly.
• When using a high-pressure washer to wash the vehicle, do not spray
water directly on the sensors. Equipment may not function prope rly if
subjected to an impact from strong water pressure. If the vehic le
bumper strikes something, equipm ent may not operate properly due to
a sensor malfunction. Have the vehicle inspected at any authori zed
Toyota retailer or Toyota author ized repairer, or any reliable repairer.
O In the following situations, the sensors may not operate normally and may
lead to an accident. Drive carefully.
• Obstacles cannot be detected in the side areas until a scan of the side
areas is completed. ( P. 456)
• Even after the scan of the side areas is completed, obstacles such as
other vehicles, people or animals that approach from the sides cannot
be detected.
• The sensor is frozen (if it thaws, the system returns to norma l).
A warning message may display at particularly low temperatures due to
the sensor freezing and it may not detect parked vehicles.
• The sensor is blocked by someone’s hand.
• The vehicle is tilted a large amount.
• The temperature is extremely hot or cold.
• The vehicle is driven on undulating roads, slopes, gravel road s, in areas
with tall grass, etc.
• An ultrasonic wave source is nearby, such as the horn or senso rs of
another vehicle, a motorcycle engine or the air brake of a larg e vehicle.
• Heavy rain or a water strikes the vehicle.
• The angle of the sensor may be deviated when assist control st arts
even if there is a parked vehicle in the target parking spot. H ave the
vehicle inspected at any authorized Toyota retailer or Toyota a uthorized
repairer, or any reliable repairer.
• Do not install any accessories within the sensor detection ran ge.

Driving
Driving assist systems
XECB (Electronically Controlled Brake System)
The electronically controlled system generates braking force corre-
sponding to the brake operation
XABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly,
or if the brakes are applied while driving on a slippery road surface
XBrake assist
Generates an increased level of braking force after the brake pedal
is depressed when the system detects a panic stop situation
XVSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces.
XVSC+ (Vehicle Stability Control+)
Provides cooperative control of the ABS, TRC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery
road surfaces by controlling steering performance.
XTRC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
XHill-start assist control
Helps to reduce the backward movement of the vehicle when start-
ing on an uphill
To keep driving safety and performance, the following systems
operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavily when operating the vehi-
cle.

5
Driving
Prius Plug-in Hybrid_OM_OM47E75E_(EE)
Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to road con-
ditions.
Park the vehicle and shift the shift position to P and block the wheel
under the vehicle without setting the parking brake. The parking brake
may freeze up, preventing it from being released. If the vehicle is
parked without setting the parking brake, make sure to block the
wheels.
Failure to do so may be dangerous because it may cause the vehicle
to move unexpectedly, possibly leading to an accident.
Use the correct tire chain size when mounting the tire chains. Chain
size is regulated for each tire size.
Side chain
3.0 mm (0.12 in.)
30.0 mm (1.18 in.)
10.0 mm (0.39 in.)
Cross chain
4.0 mm (0.16 in.)
25.0 mm (0.98 in.)
14.0 mm (0.55 in.)
Regulations regarding the use of tire chains vary depending on loca-
tion and type of road. Always check local regulations before installing
chains.

WARNING
QTo prevent the windshield from fogging up
O Do not use during cool air operation in extremely humid weather.
The difference between the temperature of the outside air and t hat of the
windshield can cause the outer surface of the windshield to fog up, block-
ing your vision.
Q To prevent burns
Do not touch the rear view mirror surfaces when the outside rea r view mirror
defoggers are on.
O Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers
from defogging.
