801-3. Emergency assistance
PRIUS_OM_OM47F01U_(U)■
Enhanced Roadside Assistance
Enhanced Roadside As
sistance adds GPS data to the already
included warranty-based Toyota roadside service.
Subscribers can press the “SOS” button to reach a Safety Connec t
response-center agent, who can he lp with a wide range of needs,
such as: towing, flat tire, fuel delivery, etc. For a description of the
Roadside Assistance services an d their limitations, please see the
Safety Connect Terms and Conditions, which are available at
Toyota.com in the United States, Toyotapr.com in Puerto Rico an d
Toyota.ca in Canada.
Important! Read this informatio n before using Safety Connect.
■Exposure to radio frequency signals
The Safety Connect system installed in your vehicle is a low-po wer
radio transmitter and receiver. I t receives and also sends out radio
frequency (RF) signals.
In August 1996, the Federal Communications Commission (FCC)
adopted RF exposure guidelines with safety levels for mobile wi re-
less phones. Those guidelines are consistent with the safety stan-
dards previously set by the following U.S. and international
standards bodies.
● ANSI (American National Stand ards Institute) C95.1 [1992]
● NCRP (National Council on Radi ation Protection and Measure-
ment) Report 86 [1986]
● ICNIRP (International Commission on Non-Ionizing Radiation
Protection) [1996]
Those standards were based on comprehensive and periodic eval-
uations of the relevant scienti fic literature. Over 120 scientists, engi-
neers, and physicians from unive rsities, and government health
agencies and industries reviewed the available body of research to
develop the ANSI Standard (C95.1).
The design of Safety Connect complies with the FCC guidelines i n
addition to those standards.

NOTICE
■When driving the vehicle
● Do not depress the accelerator and brake pedals at the same tim e during
driving, as this may restrain the hybrid system output.
● Do not use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.
■ When parking the vehicle
Always set the parking brake, and shift the shift position to P. Failure to do
so may cause the vehicle to move or the vehicle may accelerate suddenly if
the accelerator pedal is accidentally depressed.
■ Avoiding damage to vehicle parts
● Do not turn the steering wheel fully in either direction and ho ld it there for
an extended period of time.
Doing so may damage the power steering motor.
● When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
■ If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehi-
cle.
● It may be difficult to control your vehicle.
● The vehicle will make abnormal sounds or vibrations.
● The vehicle will lean abnormally.

●In the situations shown below, the system may not be able to accurately
detect surrounding brightness levels. This may cause the low be ams 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, d irty, 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 w inding
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 co ntainer 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 betwe en in
an abnormal manner.

WARNING
■Cautions regarding the use of the system
There is a limit to the degree of recognition accuracy and cont rol perfor-
mance that this system can provide, do not overly rely on this system. The
driver is always responsible for paying attention to the vehicl e’s surround-
ings and driving safely.
■ To ensure the system can operate properly
Observe the following precautions to avoid an unexpected accident.
● Do not damage the sensors, and always keep them clean.
● Do not attach a sticker or install an electronic component, such as a backlit
license plate (especially fluorescent type), fog lights, fender pole or wire-
less antenna near a radar sensor.
● Do not subject the surrounding area of the sensor to a strong impact. If
subjected to an impact, have the vehicle inspected by your Toyota dealer.
If the front or rear bumper needs to be removed/installed or replaced, con-
tact your Toyota dealer.
● Do not modify, disassemble or paint the sensors.
● Do not attach a license plate cover.
● Keep your tires properly inflated.
■ When to disable the function
In the following situations, disable the function as it may operate even
though there is no possibility of a collision.
● Failing to observe the warnings above.
● A non-genuine Toyota suspension (lowered suspension, etc.) is installed.
■ Side sensors
In the following situations, the intuitive parking assist may n ot operate nor-
mally and may result in an unexpected accident. Drive carefully.
● Obstacles may not be detected in the side areas until the vehicle is driven
for a short time and a scan of the side areas is completed. ( P. 364)
● Even after the scan of the side areas is completed, obstacles s uch as
other vehicles, people or animals that approach from the sides cannot be
detected.
● Even after the scan of the side areas is completed, obstacles may not be
detected depending on the surrounding situation of the vehicle.
At that time, the side sensor operation displays ( P. 359) temporary turn
off.
■ Notes when washing the vehicle
● Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.
● When using steam to wash the vehicle, do not direct steam too c lose to
the sensors. The sensors may not function properly if subjected to steam.
