WARNING
■When the Emergency Call may not be made
● It may not be possible to make Emergency Calls in any of the following sit-
uations. In such cases, report to emergency services provider ( 112 sys-
tem, etc.) by other means such as nearby public phones.
• Even when the vehicle is in the cellular phone service area, i t may be
difficult to connect to the eCall control center if the recepti on is poor or
the line is busy. In such cases, even though the system attempt s to con-
nect to the eCall control center, you may not be able to connec t to the
eCall control center to make Emergency Calls and contact emerge ncy
services.
• When the vehicle is out of the cellular phone service area, th e Emer-
gency Calls cannot be made.
• When any related equipment (such as the “SOS” button panel, in dicator
lights, microphone, speaker, DCM, antenna, or any wires connect ing
the equipment) is malfunctioning, damaged or broken, the Emerge ncy
Call cannot be made.
• During an Emergency Call, the system makes repeated attempts t o
connect to the eCall control center. However, if it cannot conn ect to the
eCall control center due to poor radio wave reception, the syst em may
not be able to connect to the cellular network and the call may finish
without connecting. The red indicator light will blink for appr oximately 30
seconds to indicate this disconnection.
● If the 12-volt battery’s voltage decreases or there is a disconnection, the
system may not be able to connect to the eCall control center.
● The Emergency Call system might not work outside of EU area, depend-
ing on the available infrastructure in the country.
■ When the Emergency Call system is replaced with a new one
The Emergency Call system should be registered. Contact any aut horized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.

the “READY” indicator does not come on, contact any authorized To y o t a
retailer or Toyota authorized repairer, or any reliable repaire r.
■ Running out of fuel
When the vehicle has run out of fuel and the hybrid system cann ot be started,
refuel the vehicle with at leas t enough gasoline to make the low fuel level
warning light ( P. 683) go off. If there is only a small amount of fuel, the
hybrid system may not be able to start. (The standard amount of fuel is about
7.5 L [2.0 gal., 1.7 Imp.gal.], when the vehicle is on a level surface. This value
may vary when the vehicle is on a slope. Add extra fuel when th e vehicle is
inclined.)
■ Electromagnetic waves
● High voltage parts and cables on Hybrid Electric Vehicles incorporate elec-
tromagnetic shielding, and therefore emit approximately the sam e amount
of electromagnetic waves as conventional gasoline powered vehic les or
home electronic appliances.
● Your vehicle may cause sound interference in some third party-produced
radio parts.
