When trouble arises■Warning messages
The warning messages explained
below may differ from the actual
messages according to operation
conditions and vehicle specifica-
tions.
■Warning buzzer
A buzzer may sound when a mes-
sage is displayed.
In some cases, the buzzer may not
be heard due to being in a noisy
location or audio sound.
WARNING
Your vehicle has also been
equipped with a TPMS (tire pres-
sure warning system) malfunc-
tion indicator to indicate when the
system is not opera ting properly.
The TPMS (tire pressure warning
system) malfunction indicator is
combined with the low tire pres-
sure telltale (tire pressure warning
light). When the system detects a
malfunction, the telltale will flash
for approximately one minute and
then remain continuously illumi-
nated. This sequence will con-
tinue upon subsequent vehicle
start-ups as long as the malfunc-
tion exists. When the malfunction
indicator is illuminated, the sys-
tem may not be able to detect or
signal low tire pressure as
intended.
TPMS (tire pressure warning sys-
tem) malfunctions may occur for a
variety of reasons, including the
installation of replacement or
alternate tires or wheels on the
vehicle that prevent the TPMS
(tire pressure warning system)
from functioning properly. Always
check the TPMS (tire pressure
warning system) malfunction tell-
tale after replacing one or more
tires or wheels on your vehicle to
ensure that the r eplacement or
alternate tires and wheels allow
the TPMS (tire pressure warning
system) to continue to function
properly.
NOTICE
■To ensure the tire pressure
warning system operates
properly
Do not install tires with different
specifications or makers, as the
tire pressure warning system may
not operate properly.
If a war ning message
is displayed
The multi-information dis-
play shows warnings for
system malfunctions and
incorrectly performed oper-
ations, and messages that
indicate a need for mainte-
nance. When a message is
displayed, perform the
appropriate corrective
action for the message.
If a warning message is dis-
played again after the
appropriate actions have
been performed, contact
your Toyota dealer.
Additionally, if a warning
light comes on or flashes at
the same time that a warn-
ing message is displayed,
take the appropriate correc-
tive action for the warning
light. ( P.441)

When trouble arises
The air pressure gauge will
display the actual tire inflation
pressure about 1 to 5 min-
utes after the switch is turned
on.
 Turn the compressor switch
off and then check the tire
inflation pressure. Being care-
ful not to over inflate, check
and repeat the inflation proce-
dure until the specified tire
inflation pressure is reached.
 The tire can be inflated for
about 5 to 20 minutes
(depending on the outside
temperature). If the tire infla-
tion pressure is still lower than
the specified point after infla-
tion for 25 minutes, the tire is
too damaged to be repaired.
Turn the compressor switch
off and contact your Toyota
dealer.
 If the tire inflation pressure
exceeds the specified air
pressure, let out some air to
adjust the tire inflation pres-
sure. ( P.462, 487)

off, disconnect the hose from
the valve on the tire and then

valve of the emergency
repaired tire. 17Attach the air release cap to
the end of the hose.
If the air release cap is not
attached, the sealant may leak and
the vehicle may get dirty.

while it is connected to the
compressor.
19To spread the liquid sealant evenly within the tire, imme-
diately drive safely for about
3 miles (5 km) below 50 mph
(80 km/h).
20After driving, stop your vehi- cle in a safe place on a hard,
flat surface and reconnect
the repair kit.
