●Use a soft cloth dampened with an
approximately 5% solution of neu-
tral detergent and water to clean
the dirt off.

■Repair and replacement
It is recommended that genuine
Toyota parts be used for repairs to
ensure performanc e 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 operation 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”.
You can perform some mainte-
nance procedures by yourself.

Tightening torque: 103 ft•lbf (140 N•m, 14.3
kgf•m)
WARNING
■When installing the tire
Failure to follow these precau-
tions could cause the wheel nuts
to loosen and the tire to fall off,
resulting in death o r serious injury.
●Never use oil or grease on the
wheel bolts or wheel nuts.
Oil and grease may cause the
wheel nuts to be excessively
tightened, leading to bolt or disc
wheel damage. In addition, the
oil or grease can cause the
wheel nuts to loosen and the
wheel may fall off, causing a
serious accident. Remove any
oil or grease from the wheel
bolts or wheel nuts.
●Have the wheel nuts tightened
with a torque wrench to 103
ft•lbf (140 N•m, 14.3 kgf•m) as
soon as possible after changing
wheels.
●Do not attach a heavily dam-
aged wheel ornament, as it may
fly off the wheel while the vehi-
cle is moving.
●When installing a tire, only use
wheel nuts that have been spe-
cifically designed for that wheel.

4187-3. Do-it-yourself maintenance
Owners Manual_USA_M62084_en
Use only Toyota wheel nuts
and wheel nut wrenches
designed for use with your
aluminum wheels.
 When rotating, repairing or
changing your tires, check
that the wheel nuts are still
tight after driving 1000 miles
(1600 km).
 Be careful not to damage the
aluminum wheels when using
tire chains.
 Use only Toyota genuine bal-
ance weights or equivalent
and a plastic or rubber ham-
mer when balancing your
wheels.
WARNING
■When replacing wheels
●Do not use wheels that are a dif-
ferent size from those recom-
mended in the Owner’s Manual,
as this may result in a loss of
handling control.
●Never use an inner tube in a
leaking wheel which is designed
for a tubeless tire.
Doing so may result in an acci-
dent, causing death or serious
injury.
■When installing the wheel
nuts
Never use oil or grease on the
wheel bolts or wheel nuts. Oil and
grease may cause the wheel nuts
to be excessively tightened, lead-
ing to bolt or disc wheel damage.
In addition, the oil or grease can
cause the wheel nuts to loosen
and the wheel may fall off, caus-
ing an accident and resulting in
death or serious injury. Remove
any oil or grease from the wheel
bolts or wheel nuts.
■Use of defective wheels pro-
hibited
Do not use cracked or deformed
wheels. Doing so could cause the
tire to leak air during driving, pos-
sibly causing an accident.
NOTICE
■Replacing tire pressure warn-
ing valves and transmitters
●Because tire repair or replace-
ment may affect the tire pres-
sure warning valves and
transmitters, make sure to have
tires serviced by your Toyota
dealer or other qualified service
shop. In addition, make sure to
purchase your tire pressure
warning valves and transmit-
ters at your Toyota dealer.
●Ensure that only genuine Toyota
wheels are used on your vehi-
cle.
Tire pressure warning valves
and transmitters may not work
properly with non-genuine
wheels.
