When trouble arises■Warning messages
The warning messages explained
below may differ from the actual
messages according to operation
conditions and vehicle specifica-
tions.
■Warning buzzer
A buzzer may sound when a mes-
sage is displayed.
In some cases, the buzzer may not
be heard due to being in a noisy
location or audio sound.
WARNING
Your vehicle has also been
equipped with a TPMS (tire pres-
sure warning system) malfunc-
tion indicator to indicate when the
system is not opera ting properly.
The TPMS (tire pressure warning
system) malfunction indicator is
combined with the low tire pres-
sure telltale (tire pressure warning
light). When the system detects a
malfunction, the telltale will flash
for approximately one minute and
then remain continuously illumi-
nated. This sequence will con-
tinue upon subsequent vehicle
start-ups as long as the malfunc-
tion exists. When the malfunction
indicator is illuminated, the sys-
tem may not be able to detect or
signal low tire pressure as
intended.
TPMS (tire pressure warning sys-
tem) malfunctions may occur for a
variety of reasons, including the
installation of replacement or
alternate tires or wheels on the
vehicle that prevent the TPMS
(tire pressure warning system)
from functioning properly. Always
check the TPMS (tire pressure
warning system) malfunction tell-
tale after replacing one or more
tires or wheels on your vehicle to
ensure that the r eplacement or
alternate tires and wheels allow
the TPMS (tire pressure warning
system) to continue to function
properly.
NOTICE
■To ensure the tire pressure
warning system operates
properly
Do not install tires with different
specifications or makers, as the
tire pressure warning system may
not operate properly.
If a war ning message
is displayed
The multi-information dis-
play shows warnings for
system malfunctions and
incorrectly performed oper-
ations, and messages that
indicate a need for mainte-
nance. When a message is
displayed, perform the
appropriate corrective
action for the message.
If a warning message is dis-
played again after the
appropriate actions have
been performed, contact
your Toyota dealer.
Additionally, if a warning
light comes on or flashes at
the same time that a warn-
ing message is displayed,
take the appropriate correc-
tive action for the warning
light. ( P.441)

When trouble arises
■Starting the fuel cell system
when the 12-volt battery is dis-
charged
The fuel cell system cannot be
started by push-starting.
■To prevent 12-volt battery dis-
charge
●Turn off the headlights and the
audio system while the fuel cell
system is off.
●Turn off any unnecessary electri-
cal components when the vehicle
is running at a low speed for an
extended period, such as in heavy
traffic.
■When the 12-volt battery is
removed or discharged
●Information stor ed in the ECU is
cleared. When the 12-volt battery
is depleted, have the vehicle
inspected at you r Toyota dealer.
●Some systems may require initial-
ization. ( P.510)
●If the 12-volt battery discharges, it
may not be possible to shift the
shift position to other positions.
In this case, the vehicle cannot be
towed without lifting both rear
wheels because the rear wheels will
be locked.
■When removing the 12-volt bat-
tery terminals
When the 12-volt battery terminals
are removed, the information stored
in the ECU is cleared. Before
removing the 12-volt battery termi-
nals, contact your Toyota dealer.
■Charging the 1 2-volt battery
The electricity stor ed in the 12-volt
battery will discharge gradually even
when the vehicle is not in use, due
to natural discharge and the drain-
ing effects of certain electrical appli-
ances. If the vehicle is left for a long
time, the 12-volt battery may dis-
charge, and the fuel cell system
may be unable to s tart. (The 12-volt battery recharges automatically
while the fuel cell
system is operat-
ing.)
■When recharging or replacing
the 12-volt battery
●In some cases, it may not be pos-
sible to unlock the doors using the
smart key system when the 12-
volt battery is discharged. Use the
wireless remote c ontrol or the
mechanical key to lock or unlock
the doors.
●The fuel cell system may not start
on the first attempt after the 12-
volt battery has recharged but will
start normally after the second
attempt. This is not a malfunction.
●The power switch mode is memo-
rized by the vehicle. When the 12-
volt battery is reconnected, the
system will return to the mode it
was in before the 12-volt battery
was discharged. Before discon-
necting the 12-volt battery, turn
the power switch off.
If you are unsure what mode the
power switch was in before the
12-volt battery discharged, be
especially careful when recon-
necting the 12-volt battery.
●When the 12-volt battery is recon-
nected, start the fuel cell system,
depress the brake pedal, and con-
firm that it is possible to shift into
each shift position.
●If the battery is removed or the ter-
minals disconnected without oper-
ating the water release function
during cold weather, the vehicle
may not start due to the fuel cell
system being frozen. To prevent
this, operate th e water release
function before removing the bat-
tery or disconnecting the termi-
nals. ( P.189)
■When replacing t he 12-volt bat-
tery
●Use a Central De gassing type 12-
volt battery (European Regula-
tions).
