■Repair and replacement
It is recommended that genuine
Toyota parts be used for repairs to
ensure performance of each sys-
tem. If non-Toyota parts are used in
replacement or if a repair shop other
than a Toyota dealer performs
repairs, confirm the warranty cover-
age.
■Allow inspection and repairs to
be performed by a Toyota
dealer
●Toyota technicians are well-
trained specialists and are kept up
to date with the latest service
information. They are well
informed about the operations of
all systems on your vehicle.
●Keep a copy of the repair order. It
proves that the maintenance that
has been performed is under war-
ranty coverage. If any problem
should arise while your vehicle is
under warranty, your Toyota
dealer will promptly take care of it.
General maintenance should be
performed on a daily basis. This
can be done by yourself or by a
Toyota dealer.
Scheduled maintenance should
be performed at specified inter-
vals according to the mainte-
nance schedule.
For details about maintenance
items and schedules, refer to the
“Scheduled Maintenance Guide” or
“Owner’s Manual Supplement”.
Maintenance require-
ments
To ensure safe and econom-
ical driving, day-to-day care
and regular maintenance
are essential. It is the
owner’s responsibility to
perform regular checks.
Toyota recommends the fol-
lowing maintenance:
WARNING
■If your vehicle is not properly
maintained
Improper maintenance could
result in serious damage to the
vehicle and possible death or seri-
ous injury.
■Handling of the 12-volt bat-
tery
●Engine exhaust, some of its
constituents, and a wide variety
of automobile components con-
tain or emit chemicals known to
the State of California to cause
cancer and birth defects and
other reproductive harm. Work
in a well ventilated area.
●Oils, fuels and fluids contained
in vehicles as well as waste pro-
duced by component wear con-
tain or emit chemicals known to
the State of California to cause
cancer and birth defects or
other reproductive harm. Avoid
exposure and wash any
affected area immediately.
●12-volt battery posts, terminals
and related accessories con-
tain lead and lead compounds
which are known to cause brain
damage. Wash your hands after

When trouble arises
WARNING
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) when one or more
of your tires is significantly under-
inflated. Accordingly, when the
low tire pressure telltale (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 abil-
ity.
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 maintain correct
tire pressure, even if under-infla-
tion has not reached the level to
trigger illumination of the TPMS
low tire pressure telltale (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 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 illumi nated, 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 replacement 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 manufacturers
as the tire pressure warning sys-
tem may not operate properly.
