dard, or may be cut off completely, even when the vehicle is stationary.
■ The protection circuit may be activated to cut the power supply if any
of the following conditions apply:
●The engine is started with the power outlet main switch on.
● Use of electrical appliances exceeding the maximum capacity is
attempted.
A sound may be heard when the protection circuit is activated.
This is normal and does not indicate a malfunction.
● Electrical appliances, which consume power exceeding 100W, have
been used continuously for a long time period.
● The total power usage by all electrical features (headlights, air condition-
ing, etc.) has exceeded the total vehicle maximum for an extended
period of time.
■ If the protection circuit is activated and the power supply is cut, con-
duct the following procedure:
Park the vehicle in a safe place, and then securely apply the park-
ing brake.
Check and ensure the following conditions:• The shift lever is in P or N. (automatic transmission)
• The shift lever is in N and the clutch pedal is not depressed. (manual transmission)
Make sure that the power consumption of the electric appliance is
within the maximum capacity of the power outlet and the appliance
is not broken.
Press the power outlet main switch again.
When the cabin temperature is high, open the windows to cool the tempera-
ture down. Once it reaches the normal temperature, turn the power outlet
main switch on again.
If the power supply is not resumed even after performing the above proce-
dure, have the vehicle inspected by a Toyota dealer.

valve and transmitter. If a tire goes flat, the tire pressure warning light will
not turn off even though the flat tire is replaced with the temporary spare
tire. Replace the temporary spare tire with the repaired tire and adjust
the proper tire inflatio n pressure. The tire pres sure warning light will turn
off after a few minutes.
