● After charging the 12-volt battery, the message may not go off until the shift
position is changed from P.
■ If “Shifting Unavailable Low 12-Volt Battery See Owner’s Manual” is
shown
Indicates that the shift position cannot be changed because the voltage of the
12-volt battery drops. Charge or replace the 12-volt battery.
(Coping method in the case the 12-volt battery is discharged: P. 711)

position is in N, when stopped for long periods of time shift the shift position to
P.
■ If “Hybrid Battery Low Hybrid Syst em Stopped Shift to and Restart”
is shown
Message is displayed when the remaining charge for the hybrid battery (trac-
tion battery) is low, because vehicle has been shifted to N for a long period of
time.
When operating the vehicle, shift to P and restart the hybrid system.

When trouble arises
Inflate the tire until the specified air pressure is reached.The sealant will be injected
and the pressure will spike to
between 44 psi (300 kPa,
3.0 kgf/cm
2 or bar) and
58 psi (400 kPa, 4.0 kgf/cm2
or bar), then gradually
decrease.
The air pressure gauge will
display the actual tire infla-
tion pressure about 1 to 5
minutes after the switch is
turned on.
• Turn the compressor switch off and then check the tire
inflation pressure. Being
careful not to over inflate,
check and repeat the inflation
procedure until the specified
tire inflation pressure is
reached.
• The tire can be inflated for about 5 to 20 minutes (depending on the outside temperature). If the tire inflation pressure is still lower
than the specified point after inflation for 25 minutes, the tire is
too damaged to be repaired. Turn the compressor switch off and
contact your Toyota dealer.
• If the tire inflation pressure exce eds the specified air pressure, let
out some air to adjust the tire inflation pressure. ( P. 700, 734)
With the compressor switch off, disconnect the hose from the valve
on the tire and then pull out the power plug from the power outlet
socket.
Some sealant may leak when the hose is removed.
Install the valve cap onto the valve of the emergency repaired tire.
