When trouble arises
4RUNNER (U)_(OM35A83U)■
The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such
as natural air leaks and tire inflation pressure changes caused by temper-
ature. In this case, adjusting the ti
re inflation pressure will turn off the
warning light (after a few minutes).
■When a tire is replaced with a spare tire
The spare tire is not equipped with a tire pressure warning valve and
transmitter. If a tire goes flat, the tire pressure warning light will not turn off
even though the flat tire has been r eplaced with the spare tire. Replace
the spare tire with the repaired tire and 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 condi-
tions:
(When the condition be comes 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 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or
higher
The tire pressure warning system may be disabled in the following condi-
tions:
(When the condition be comes normal, the system will work properly.)
●If electronic devices or facilities using similar radio wave frequencies are
nearby
●If a radio set at a similar frequency is in use in the vehicle
●If a window tint that affects the radio wave signals is installed
●If there is a lot of snow or ice on the vehicle, particularly around the
wheels 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
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 your
Toyota dealer.
■ Customization that can be co nfigured at Toyota dealer
The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features P. 485) However, Toyota recommends that the seat
belt reminder buzzer be operational to alert the driver and front passenger
when seat belts are not fastened.

Improper use of the tire jack may cause the vehicle to suddenly fall off
the jack, leading to death or serious injury.
●Do not use the tire jack for any purpose other than replacing tires or
installing and removing tire chains.
●Only use the tire jack that comes with this vehicle for replacing a flat
tire.
Do not use it on other vehicles, and do not use other tire jacks for
replacing tires on this vehicle.

*: The engine oil capacity is a reference quantity to be used when changingthe engine oil. Warm up and turn off the engine, wait more than 5 minutes,
and check the oil level on the dipstick.
■
Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to sat-
isfy the following grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice
for good fuel economy and
good starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change.
Oil viscosity (0W-20 is explained here as an example): • The 0W in 0W-20 indicates the characteristic of the oil which
allows cold startability. Oils wi th a lower value before the W allow
for easier starting of the engine in cold weather.
• The 20 in 0W-20 indicates the viscosity characteristic of the oil when the oil is at high temperature. An oil with a higher viscosity
(one with a higher value) may be better suited if the vehicle is
operated at high speeds, or under extreme load conditions.
