6-3. Do-it-yourself maintenance
●
The tire pressure warning system
can be initialized by yourself, but
depending on the driving condi-
tions and driving environment, ini-
tialization may take some time to
complete.
■
The initialization operation
●
If you have accidentally turned the
power switch to OFF during initial-
ization, it is not necessary to
restart the initialization again as
initialization will restart automati-
cally when the power switch has
been turned to ON for the next
time.
●
If you accidentally perform initial-
ization when initialization is not
necessary, adjust the tire inflation
pressure to the specified level
when the tires are cold, and con-
duct initialization again.
●
While the position of each tire is
being determined and the inflation
pressures are not being displayed
on the multi-information display, if
the inflation pressure of a tire
drops, the tire pressure warning
light will come on.
■
If the tire pressure warning sys-
tem is not initialized properly
●
In the following situations, initial-
ization may take longer than usual
to be completed or may not be
possible. Normally, initialization
completes within approximately
30 minutes.
• Vehicle is not driven at approxi-
mately 25 mph (40 km/h) or more
• Vehicle is driven on unpaved
roads
• Vehicle is driven near other vehi-
cles and system cannot recog-
nize tire pressure warning valve
and transmitters of your vehicle
over those of other vehicles.
• If the vehicle is driven in heavy
traffic or another situation where
other vehicles are driven close by,
it may take time for the system to
recognize the tire pressure warn-
ing valve and transmitters of your
vehicle over those of other vehi-
cles.
●
If initialization does not complete
after driving for 1 hour or more,
park the vehicle in a safe place for
approximately 20 minutes and
then drive the vehicle again.
●
If the vehicle is reversed during
initialization, the data up to that
point is reset, so perform the ini-
tialization procedure again from
the beginning.
●
In the following situations, initial-
ization will not be started or was
not completed properly and the
system will not operate properly.
Perform the initialization proce-
dure again.
• If, when attempting to start initial-
ization, the tire pressure warning
light does not blink 3 times.
• If, when the vehicle 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 proce-
dure, contact your Toyota dealer.
WARNING
■
When initializing the tire pres-
sure warning system
Do not initialize tire inflation pres-
sure without first adjusting the tire
inflation pressure to the specified
level. Otherwise, the tire pressure
warning light may not come on
even if the tire inflation pressure is
low, or it may come on when the
tire inflation pressure is actually
normal.
