4366-3. Do-it-yourself maintenance
4RUNNER (U)■
The initialization operation
●Make sure to carry out initializ
ation after adjusting the tire inflation pres-
sure.
Also, make sure the tires are co ld before carrying out initialization or tire
inflation pressure adjustment.
●If you have accidentally turned the engine switch off during in itialization,
it is not necessary to press the reset swit ch again as initialization will
restart automatically when the engine switch has been turned to IGNI-
TION ON mode for the next time.
●If you accidentally press the reset switch when initialization is not neces-
sary, adjust the tire inflation pressure to the specified level when the
tires are cold, and cond uct initialization again.
●While the position of each tire is being determined and the inf lation pres-
sures are not being displayed on the multi-information display, if the
inflation pressure of a tire drops, the tire pressure warning l ight will come
on.
■When initialization of the tire pressure warning system has fai led
●Do not move the vehicle backward during initialization. Initialization is
started again from the beginning and it may take longer than usual.
●Initialization may take longer to complete if the vehicle is driven on an
unpaved road.
When performing initialization, drive on a paved road if possib le.
Depending on the driving environment and condition of the tires , initial-
ization will be complet ed in approximately 10 to 30 minutes.
• If initialization is not complet e after driving approximately 30 minutes,
continue driving for a while.
• If initialization is not complet e after driving approximately 1 hour, park
the vehicle in a safe place for approximately 20 minutes. Then drive
straight (with occasional left a nd right turns) at approximatel y 25 mph
(40 km/h) or more
* for approximately 10 to 30 minutes.
• If initialization is still not co mplete, have the vehicle inspected by your
Toyota dealer.
*: Except when making a left/right turn
●In the following situations, the tire inflation pressure will n ot be recorded
and the system will not operate p roperly. Perform initialization again.
• When operating the tire pressure warning reset switch, the tir e pres-
sure warning light does not blink 3 times.
• After performing initialization, the tire pressure warning light blinks for
1 minute then stays on after driving for about 20 minutes.

WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as
dangerous handling characteristics, which may lead to an accide nt
resulting in death o r serious injury.
●Do not mix tires of different ma kes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other th an those recommended by Toyota.
●Do not mix differently constructed tires (radial, bias-belted o r bias-ply
tires).
●Do not mix summer, all season and snow tires.
●Do not use tires that have been used on another vehicle.
Do not use tires if you do not kn ow how they were used previous l y.
■When initializing the tire pressure warning system
Do not operate the tire pressure warning reset switch without first
adjusting the tire inflation pressure to the specified level. O therwise, the
tire pressure warning light may not come on even if the tire in flation
pressure is low, or it may come on when the tire inflation pres sure is
actually normal.

5087-2. Steps to take in an emergency
4RUNNER (U)
Repeat step any time the tire is lowered or disturbed.
Stow the tools and jack securely.
■After completing the tire change
The tire pressure warni ng system must be reset. ( P. 430)
■When using the spare tire (veh icles without P245/60R20 tires)
As the spare tire is not equipped with a tire pressure warning valve and
transmitter, low inflation pressure of the spare tire will not be indicated by
the tire pressure warning system. Also, if you replace the spar e tire after
the tire pressure wa rning light comes on, the light remains on.
NOTICE
■Do not drive the vehicle with a flat tire
Do not continue driving with a flat tire.
Driving even a short distance wit h a flat tire can damage the tire and the
wheel beyond repair.
■When stowing the flat tire
Ensure that there is no object c aught between the tire and the vehicle
underbody.
■When replacing the tires
●When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact your Toyota dealer as the tire p ressure
warning valve and transmitter may be damaged if not handled cor -
rectly.
●Replace the grommets for the tire pressure warning valves and trans-
mitters as well.
■To avoid damage to the tire pressure warning valves and transmi t-
ters
When a tire is repaired with liquid sealants, the tire pressure warning valve and transmitter may not operate properly. If a liquid sea lant is
used, contact your Toyota dealer or other qualified service shop as soon
as possible. Make sure to replace the tire pressure warning valve and
transmitter when replacing the tire. ( P. 430)
