: If equipped
⬛If the open door warning light✽ comes on
To avoid battery discharge, the warning light will automatically turn OFF after
about 10 minutes with the engine switch in “ACC” or “OFF”, and the door left
open.
⬛When the tire pressure warning light comes on (vehicles with a tire
pressure warning system)
Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured: ➞P. 3 9 6
If the tire is not punctured:
Carry out the following procedure after the tire temperature has lowered suffi-
ciently.
⚫Check the tire inflation pressure and adjust to the appropriate level.
⚫If the warning light does not go out even after several minutes, check that
the tire inflation pressure is at the sp ecified level and carry out initialization.
The warning light may come on again if the above operations are conducted
without first allowing the tire temperature to lower sufficiently.
⬛The tire pressure warning light may come on due to natural causes
(vehicles with a tire pressure warning system)
The tire pressure warning light may come on due to natural causes such as
natural air leaks and tire inflation pressure changes caused by temperature.
In this case, adjusting the tire inflatio n pressure will turn off the warning light
(after a few minutes).
⬛When a tire is replaced with a spare tire (vehicles with a tire pressure
warning system)
The spare tire is also equipped with a tire pressure warning valve and transmit-
ter. The tire pressure warning light will tu rn on if the tire inflation pressure of
the spare tire is low. If a tire goes flat, the tire pressure warning light will not
turn off even though the flat tire has been replaced with the spare tire. Replace
the spare tire with the repaired tire an d adjust the tire inflation pressure. The
tire pressure warning light will go off after a few minutes.
⬛If the tire pressure warning system is not functioning✽
The tire pressure warning system will be disabled in the following conditions:
(When the condition becomes normal, the system will work properly.)
⚫If tires not equipped with tire pressure warning valves and transmitters are
used
⚫If the ID code on the tire pressure warning valves and transmitters is not reg-
istered in the tire pressure warning computer
⚫If the tire inflation pressure is higher than the specified tire air pressure.

a Stop the vehicle in a safe place an d turn OFF the air conditioning sys-
tem, and then stop the engine
b If you see steam:
After making sure that the steam has stopped, carefully lift the hood
If you do not see steam:
Carefully lift the hood

down sufficiently, inspect the
hoses and radiator core (radiat-
ing part) for any leaks

eAdd coolant if necessary
Water can be used in an emergency if
coolant is unavailable.
fStart the engine and turn the air co nditioning system on to check that
the radiator cooling fan operates and to check again for coolant leaks
from the radiator core or hoses
The fan operates when the air conditioning system is turned on immediately after a
cold start. Confirm that the fan is operat ing by checking the fan sound and air flow.
If it is difficult to check them, turn the air conditioning system ON and OFF repeat-
edly.
(The fan may not operate in freezing temperatures)
g If the fan is not operating:
Stop the engine immediately and contact your Toyota dealer
If the fan is operating:
Have the vehicle inspected at the nearest Toyota dealer
WARNING
⬛Before taking measures
Do not remove the radiator cap if the coolant is hot. The radiator cap is under
the pressure of the coolant. Therefore, steam or hot water may spurt out of it,
causing serious injury such as burns.
⬛To prevent an accident or injury when inspecting under the hood of your
vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
⚫If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot.
⚫Keep hands and clothing (especially a tie, a scarf or a muffler) away from the
fan and belts. Failure to do so may caus e the hands or clothing to be caught,
resulting in serious injury.
⚫Do not loosen the radiator cap an d the coolant reservoir cap while the
engine and radiator are hot. High te mperature steam or coolant could spray
out.
