Maintenance and care
■When replacing wheels
The wheels of your Toyota are equipped with tire pressure warning
valves and transmitters (except for sp
are tire) that allow the tire pressure
warning system to provide advanced warning in the event of a loss in tire
inflation pressure. Whenever wheels are replaced, the tire pressure
warning valves and transmitte rs must be installed. (P. 453)
CAUTION
■When replacing wheels
●Do not use wheels that are a different size from those recommended in
the Owner’s Manual, as this may re sult in 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 accident, causing death or seri-
ous 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,
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 an
accident and resulting in death or serious injury. Remove any oil or
grease from the wheel bolts or wheel nuts.
●Be sure to install the wheel nuts with
the tapered end faci ng inward. Install-
ing the nuts with the tapered end fac-
ing outward can cause wheel to
break and eventually cause a wheel
to come off while driving, which could
lead to an accident resulting in death
or serious injury.Tapered

the system operating abnormally and possibly cause an accident.
Have the vehicle inspected by your Toyota dealer immediately.

Tire pressure warning
light
When the light comes on:
Low tire inflation pressure
such as
• Natural causes
( P. 510)
• Flat tire ( P. 515) Adjust the tire inflation
pressure to the speci-
fied level.
The light will turn off
after a few minutes.
In case the light
does not turn off
even if the tire infla-
tion pressure is
adjusted, have the
system checked by
your Toyota dealer.
• When the light stays on after blinking for 1
minute: Malfunction in
the tire pressure warning
system. ( P. 511) Have the system
checked by your
Toyota dealer.
Low fuel level warning
light
Low level of fuel. Refuel the vehicle.
(U.S.A.) Engine oil replacement
reminder light
• Illuminates for about 3
seconds and then flashes
for about 15 seconds: Indi-
cates that the engine oil is
scheduled to be changed. Check the engine oil,
and change if neces-
sary.

Warning lightWarning light/DetailsCorrection procedure

512 5-2. Steps to take in an emergency
■After changing the engine oil (U.S.A. only)
Make sure to reset the oil maintenance data. ( P. 441)
■ Customization that can be co nfigured at Toyota dealer
The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features P. 583)
CAUTION
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could
cause loss of vehicle control and re sult in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire
inflation pressure immediately.
●If the tire pressure warning light comes on even after tire inflation pres-
sure adjustment, it is pr obable that you have a flat tire. Check the tires.
If the tire is flat, change to the spare tire and have the flat tire repaired
by the nearest Toyota 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 syste m may not activate immediately.
■Maintenance of the tire
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pressure
label (tire and load information label). (If your vehicle has tires of a differ-
ent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine the
proper tire inflation pr essure for those tires.)
