1382-2. Charging
and use the external power
source only at night. As a result,
the solar charging system can be
used effectively.
●When the vehicle is left in the hot
weather, the temperature preser-
vation function of the solar
charging system becomes easy to
operate due to high temperature
of the vehicle interior.
●Applying a glass coating to the
solar roof may change the refrac-
tive index of light and reduce the
amount of power generated.
●Small dots, lines, and stains may
be visible inside the solar roof,
however there is no problem with
the power generation function or
safety.
NOTICE
■To protect the solar charging
system from damage
●Make sure to observe the fol-
lowing precautions.
• Do not modify the solar roof
• Do not condense sunlight onto the solar roof
• Do not place anything on top of the solar roof
• Do not subject the solar roof to strong impacts or apply force
with sharp objects from the
inside roof of the vehicle.
●If the solar roof is damaged, do
not touch the damaged area
and immediately request repairs
from your Toyota dealer.

■If “Charging Stopped High Energy Use See Owner’s Manual”
is shown
■If “Charging System Malfunction See Owner’s Manual” is
shown
■If “The Traction Battery Temp is low System put priority on
charging to preserve battery condition” is shown (Alaska and
Canada only)
Likely causeCorrection procedure
Power is being consumed by electri-
cal components of vehicle
Check the following items, and then
carry out charging again.
If the headlights and audio are
turned on, turn them off.
 Turn the power switch off.
If charging cannot be carried out,
even after performing the above, the
auxiliary battery may not be suffi-
ciently charged. Operate the hybrid
system for approximately 15 minutes
or more to charge the 12-volt battery.
Likely causeCorrection procedure
Malfunction occurred in charging
systemHave the vehicle inspected by your
Toyota dealer.
Likely causeCorrection procedure
The Hybrid battery (traction battery)
warming control was operated
(  P.109)
When the hybrid battery (traction
battery) warming control operates,
the charging schedule is not used
and charging is performed.
This is a control to protect the hybrid
battery (traction battery), and not a
malfunction.

WARNING
■If a safety system warning
light does not come on
Should a safety system light such
as the ABS and SRS warning light
not come on when you start the
hybrid system, this could mean
that these systems are not avail-
able to help protect you in an acci-
dent, which could result in death
or serious injury. Have the vehicle
inspected by your Toyota dealer
immediately if this occurs.

tery) is fully charged
The hybrid battery (traction bat-
tery) for EV mode is not remain-
ing
■Distance to empty
●This distance is computed based
on your average fuel consump-
tion. As a result, the actual dis-
tance that can be driven may
differ from that displayed.
●When only a small amount of fuel
is added to the tank, the display
may not be updated. When refuel-
ing, turn the power switch off. If
the vehicle is refueled without
turning the power switch off, the
display may not be updated.
●When “Refuel” is displayed, the
remaining fuel amount is low and
the distance that can be driven
with the remaining fuel cannot be
calculated. Refuel immediately.
■EV driving range
●When the air conditioning system
is operating, is displayed next
to the EV driving range and the
EV driving range with the air con-
ditioning system on is displayed.
●The EV driving range may shorten
even when not driving due to
power consumption by the sys-
tem.
●For details, refer to “EV driving
range” (P.90)
■Outside temperature display
●Displays the outside temperature
within the range of -40°F (-40°C)
to 140°F (60°C).
●When the outside temperature is
approximately 37°F (3°C) or
lower, the indicator will flash
for approximately 10 seconds,
then stay on.
●In the following situations, the cor-
rect outside temperature may not
be displayed, or the display may
take longer th an normal to
change.
• When stopped, or driving at low speeds (less than 12 mph [20
km/h])
• When the outside temperature has changed suddenly (at the
entrance/exit of a garage, tunnel,
etc.)
●When “--” or “E” is displayed, the
system may be malfunctioning.
Take your vehicle to your Toyota
dealer.
■Liquid crystal display
Small spots or light spots may
appear on the display. This phe-
nomenon is characteristic of liquid
crystal displays, and there is no
problem continuing to use the dis-
play.
