*: This button is intended for commu-
nication with the ERA-GLONASS/
EVAK system operator.
Other SOS buttons available in
other systems of a motor vehicle do
not relate to the device and are not
intended for communication with
the ERA-GLONASS/EVAK system
operator.
1: If equipped
2: Operates within regions offering emergency notification services. Ask any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer for details.
3: The system name differs depending on the country.
The Emergency Call system is a device installed on a vehicle to
determine its location and movement direction (using GLONASS
[Global Navigation Satellite System] and GPS [Global Position-
ing System] signals), and ensure the generation and transmis-
sion of vehicle information (in a nonadjustable form) in case of
traffic accidents or other incidents on motor roads in the coun-
tries offering emergency notification services. In addition, it
ensures two-way voice communication between the vehicle and
an ERA-GLONASS/EVAK system operator through cellular net-
works (GSM).
Automatic Emergency Calls (via Automatic Collision Notifica-
tion) and manual Emergency Calls (by pressing the “SOS” but-
ton) can be made to the ERA-GLONASS/EVAK control center.
This service is mandatory according to the technical regulations
of the Customs Union.

2944-5. Using the driving support systems
PRIUS_OM_OM47F32E_(EE)■If 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.
●In 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. 462)
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.

● Do not touch the glass portion of the light bulb with bare hands. When it is
unavoidable to hold the glass portion, use and hold with a clean dry cloth
to avoid getting moisture and oils on the bulb.
Also, if the bulb is scratched or dropped, it may blow out or crack.

may result in heat damage, fire, or water entering the headlight unit. This
may damage the headlights or cause condensation to build up on the lens.
● Do not attempt to repair or disassemble light bulbs, connectors, electric
circuits or component parts.
Doing so may result in death or serious injury due to electric shock.
■ To prevent damage or fire
● Make sure bulbs are fully seated and locked.
● Check the wattage of the bulb before installing to prevent heat damage.
