Maintenance and care
If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
Situations in which the tire pressure warning system may not operate
properly (vehicles with a tire pressure warning system)
In the following cases, the tire pressure warning system may not operate
properly.
• If non-genuine Toyota wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equipment)
tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are equipped.
• Lock nuts are equipped.
• An auxiliary-supported run-flat tire is equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the
wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the specified level.
• If tires not equipped with tire pressure warning valves and transmitters
are used.
• If the ID code on the tire pressure warning valves and transmitters is not
registered in the tire pressure warning computer.
Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electri-
cal noise.
• When carrying a portable radio, cellular phone, cordless phone or other
wireless communication device.
When the vehicle is parked, the time taken for the warning to start or go off
could be extended.
When tire inflation pressure declines rapidly for example when a tire has
burst, the warning may not function.

CAUTION
When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as
dangerous handling characteristics, which may lead to an accident resulting
in death or serious injury.
Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
Do not use tire sizes other than those recommended by Toyota.
Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
Do not mix summer, all season and snow tires.
Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
Vehicles with a compact spare tire: Do not tow if your vehicle has a com-
pact spare tire installed.
When initializing the tire pressure warning system (vehicles with a tire
pressure warning system)
Do not operate the tire pressure warning reset switch without first adjusting
the tire inflation pressure to the specified level. Otherwise, the tire pressure
warning light may not come on even if the tire inflation pressure is low, or it
may come on when the tire inflation pressure is actually normal.

When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim width and
inset
*.
Replacement wheels are available at any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
*: Conventionally referred to as “offset”.
Toyota does not recommend using the following:
Wheels of different sizes or types
Used wheels
Bent wheels that have been straightened
Use only Toyota wheel nuts and 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 1600 km (1000 miles).
Be careful not to damage the aluminum wheels when using tire
chains.
Use only Toyota genuine balance weights or equivalent and a plas-
tic or rubber hammer when balancing your wheels.
When replacing wheels (vehicles with a tire pressure warning system)
The wheels of your vehicle (except spare tire) are equipped with tire pressure
warning valves and transmitters that allow the tire pressure warning system
to provide advance warning in the event of a loss in tire inflation pressure.
Whenever wheels are replaced, tire pressure warning valves and transmitters
must be installed. (P. 537)
Wheels
If a wheel is bent, cracked or heavily corroded, it should be
replaced. Otherwise, the tire may separate from the wheel or
cause a loss of handling control.

Maintenance and care
When removing the wheel ornament (vehicles with the wheel cap clip)
Remove the wheel ornament using the
wheel cap clip.
CAUTION
When replacing wheels
Do not use wheels that are a different size from those recommended 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 tube-
less tire. Doing so may result in an accident, 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,
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 acci-
dent and resulting in death or serious injury. Remove any oil or grease
from the wheel bolts or wheel nuts.
Use of defective wheels prohibited (vehicles with aluminum wheels)
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing an
accident.
Be sure to install the wheel nuts with the
tapered ends facing inward. Installing
the nuts with the tapered ends facing
outward can cause the wheel to break
and eventually cause the wheel to come
off while driving, which could lead to an
accident resulting in death or serious
injury.

CAUTION
When storing the spare tire
Be careful not to catch fingers or other body parts between the spare tire
and the body of the vehicle.

When trouble arises
Turn the tire jack portion “A” by
hand until the notch of the jack
is in contact with the jack point.
The jack point guides are located
under the rocker panel. They indi-
cate the jack point positions.
Raise the vehicle until the tire is slightly raised off the ground.
Remove all the wheel nuts and
the tire.
When resting the tire on the
ground, place the tire so that the
wheel design faces up to avoid
scratching the wheel surface.

When trouble arises
Install the tire and loosely tighten each wheel nut by hand by
approximately the same amount.
When replacing a steel wheel
with a steel wheel (including a
compact spare tire), tighten the
wheel nuts until the tapered
portion comes into loose con-
tact with the disc wheel seat.
When replacing an aluminum
wheel with a steel wheel
(including a compact spare
tire), tighten the wheel nuts until
the tapered portion comes into
loose contact with the disc
