PRIUS_OM_OM47F32E_(EE)
WARNING
■For your safety
● Please drive safely.
The function of this system is to assist you in making the Emergency Call
in case of accidents such as traffic accidents or sudden medical emergen-
cies, and it does not protect the driver or passengers in any way. Please
drive safely and fasten your seatbelts at all times for your safety.
● In case of an emergency, make lives the top priority.
● If you smell anything burning or other unusual smells, leave the vehicle
and evacuate to a safe area immediately.
● Since the system detects shocks, the automatic reporting may not always
occur synchronized with the operation of the airbag system. (If the vehicle
is struck from behind, etc.)
● For safety, do not make the Emergency Call while driving.
Making calls during driving may caus e mishandling of the steering wheel,
which may lead to unexpected accidents.
Stop the vehicle and confirm the safety of your surroundings before mak-
ing the Emergency Call.
● When changing fuses, please use the specified fuses. Using other fuses
may cause ignition or smoke in the circuit and lead to a fire.
● Using the system while there is smoke or an unusual smell may cause a
fire. Stop using the system immediately and consult any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
NOTICE
■ To prevent damage
Do not pour any liquids onto the “SOS” button panel, etc. and do not impact
it.
■ If the “SOS” button panel, speaker or microphone malfunctions during
an Emergency Call or manual maintenance check
It may not be possible to make Emergency Calls, confirm the system status,
or communicate with the ERA-GLONASS/EVAK control center operator. If
any of the above equipment is damaged, please consult any authorized
Toyota retailer, Toyota authorized repairer, or any reliable repairer.

NOTICE
■Hybrid battery (traction battery) air intake vent
● Make sure not to block the air intake vent with anything, such as a seat
cover, plastic cover, or luggage. If the vent is blocked, the charging/dis-
charging of the hybrid battery (traction battery) may become limited.
● When dust etc. has accumulated in the air intake vent, clean it with a vac-
uum cleaner to prevent the vent from clogging.
● Do not get water or foreign materials in the air intake vent as this may
cause a short circuit and damage the hybrid battery (traction battery).
● Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction battery), the battery
may be damaged. Have the vehicle inspected by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
● There is a filter installed to the air intake vent. When the filter remains
noticeably dirty even after cleaning the air intake vent, filter cleaning or
replacement is recommended. For information regarding filter cleaning or
replacement, refer to P. 545.
● If “Maintenance Required for Traction Battery Cooling Parts See Owner's
Manual” is shown on the multi-information display, the air intake vent and
filter may be clogged. Refer to P. 545 for information on how to clean the
air intake vent.
