Maintenance and care
●If you accidentally perform initializa-
tion when initializ ation is not neces- sary, adjust the tire inflation pressure
to the specified level when the tires
are cold, and conduct initialization again.
●While the position of each tire is being determined and the inflation pres -
sures are not being displayed on the
multi-information display, if the infla - tion pressure of a ti re drops, the tire
pressure warning light will come on.
■If the tire pressure warning system
is not initialized properly
●In the following situations, initialization
may take longer than usual to be com - pleted or may not be possible. Nor -
mally, initialization completes within
approximately 30 minutes. • Vehicle is not drive n at approximately
40 km/h (25 mph) or more
• Vehicle is driven on unpaved roads • Vehicle is driven near other vehicles
and system cannot recognize tire
pressure warning valve and transmit - ters of your vehicle over those of other
vehicles.
• If the vehicle is dri ven in heavy traffic or another situation where other vehi -
cles are driven close by, it may take
time for the system t o recognize the tire pressure warning valve and trans -
mitters of your vehicle over those of
other vehicles.
●If initialization does not complete after
driving for 1 hour or more, park the vehicle in a safe place for approxi-
mately 20 minutes and then drive the
vehicle again.
●If the vehicle is rev ersed during initial-
ization, the data up to that point is
reset, so perform the initialization pro - cedure again from the beginning.
●In the following situations, initialization will not be started or was not com -
pleted properly and the system will not
operate properly. Pe rform the initial- ization procedure again.
• If, when attempting to start initializa -
tion, the tire pressure warning light
does not blink 3 times.
• If, when the vehicl e has been driven for about 20 minutes after performing
initialization, the tire pressure warning
light blinks for approximately 1 minute and then illuminates.
If initialization cannot be completed after
performing the above procedure, con -
tact any authorized T oyota retailer or
Toyota authorized repairer, or any reli -
able repairer.
Every tire pressure warning valve

WARNING
■When initializing the tire pres -
sure warning system
Do not initialize tire inflation pressure without first adjusting the tire inflation
pressure to the specified level. Other -
wise, the tire pressu re warning light may not come on even if the tire infla-
tion pressure is lo w, or it may come
on when the tire inf lation pressure is actually normal.
