WARNING
●If the tire pressure warning light 
comes on even after tire infla-
tion pressure adjustment, it is 
probable that you have a flat 
tire. Check the tires. If a tire is 
flat, change it with the spare tire 
and have the flat tire repaired by 
the nearest Toy ota dealer.
●Avoid abrupt maneuvering and 
braking.
If the vehicle tires deteriorate, 
you could lose control of the 
steering wheel or the brakes.
■If a blowout or sudden air 
leakage should occur
The tire pressure warning system 
may not activate immediately.
■Maintenance of the tires
Each tire, including the spare (if 
provided), should be checked 
monthly when cold and inflated to 
the inflation pressure recom-
mended by the vehicle manufac-
turer on the vehicle placard or tire 
inflation pressure label (tire and 
load information label). (If your 
vehicle has tires of a different size 
than the size indicated on the 
vehicle placard or tire inflation 
pressure label [tire and load infor-
mation label], you should deter-
mine the proper tire inflation 
pressure for those tires.)
As an added safety feature, your 
vehicle has been equipped with a 
tire pressure monitoring system 
(TPMS-tire pressure warning sys-
tem) that illuminates a low tire 
pressure telltale (tire pressure 
warning light) w hen one or more 
of your tires is s ignificantly under-
inflated. Accordingly, when the 
low tire pressure te lltale (tire pres-
sure warning light) illuminates, 
you should stop and check your 
tires as soon as possible, and 
inflate them to the proper pres-
sure. Driving on a significantly 
under-inflated tire causes the tire 
to overheat and can lead to tire 
failure. Under-inflation also 
reduces fuel efficiency and tire 
tread life, and may  affect the vehi-
cle’s handling and stopping ability.
Please note that the TPMS (tire 
pressure warning system) is not a 
substitute for proper tire mainte-
nance, and it is the driver’s 
responsibility to m aintain correct 
tire pressure, even  if under-infla-
tion has not reached the level to 
trigger illumination of the TPMS 
low tire pressure te lltale (tire pres-
sure warning light).
Your vehicle has also been 
equipped with a TPMS (tire pres-
sure warning system) malfunc-
tion indicator to indicate when the 
system is not operating 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 te lltale 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 ab le to detect or 
signal low tire pressure as 
intended.

When trouble arises
■Warning messages
The warning messages explained 
below may differ from the actual 
messages according to operation 
conditions and vehicle specifica-
tions.
■If a message about an operation 
is displayed
●If a message about an operation 
of the accelerator pedal or brake 
pedal is displayed
A warning message about an opera-
tion of the brake pedal may be 
shown while the driving assist sys-
WARNING
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 manufactures as 
the tire pressure  warning system 
may not operate properly.
If  a war ning message 
is displayed
The multi-information dis-
play shows warnings of 
system malfunctions, incor-
rectly performed opera-
tions, and messages that 
indicate a need for mainte-
nance. When a message is 
shown, perform the correc-
tion procedure appropriate 
to the message.
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.501)
If a warning message is dis-
played again after the 
appropriate actions have 
been performed, contact 
your Toyota dealer.
