■ If the engine oil change reminder light flashes (diesel engine with a DPF
system)
Repeated short trips and/or low-speed dr iving may cause the oil to degrade
sooner than usual, regardless of the actual distance driven. If this happens,
the engine oil change reminder light will flash.
■ Engine oil change reminder light comes on (diesel engine only)
Vehicles without a DPF system
Replace the engine oil and oil filter when the engine oil change reminder light
does not come on even if you have driven over 40000 km (25000 miles) after
the engine oil was changed.
There is a possibility that the engine oil change reminder light has been illumi-
nated when you have driven less than 40000 km (25000 miles) based on a
usage or driving condition.
Vehicles with a DPF system
Replace the engine oil and oil filter when the engine oil change reminder light
does not come on even if you have driven over 15000 km (9300 miles) after
the engine oil was changed.
There is a possibility that the engine oil change reminder light has been illumi-
nated when you have driven less than 15000 km (9300 miles) based on a
usage or driving condition.
■ When the tire pressure warning light comes on (vehicles with a tire pres-
sure warning system)
Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured: P. 445, 460
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.

the tire inflation pressure is at the specified 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 inflation 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 not equipped with a tire pressure warning valve and trans-
mitter. 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 and adjust the tire inflation pressure. The tire pres-
sure warning light will go off after a few minutes.
■ If the tire pressure warning system is not functioning (vehicles with a
tire pressure warning system)
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
registered in the tire pressure warning computer
● If the tire inflation pressure is 500 kPa (5.1 kgf/cm2 or bar, 73 psi) or higher
The tire pressure warning system may be disabled in the following conditions:
(When the condition becomes normal, the system will work properly.)

or wheel housings
● If non-genuine Toyota wheels are used (Even if you use Toyota wheels, the
tire pressure warning system may not work properly with some types of
tires.)
● If tire chains are used
■ If the tire pressure warning light frequently comes on after blinking for 1
minute (vehicles with a tire pressure warning system)
If the tire pressure warning light frequently comes on after blinking for 1
minute when the engine switch is turned on, have it checked by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped profes-
