WARNING
■Replacing a flat tire
●Do not touch the disc wheels or the
area around the brakes immedi- ately after the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around the brakes will be extremely
hot. Touching these areas with hands, feet or other body parts while changing a tire, etc. may
result in burns.
●Failure to follow these precautions
could cause the wheel bolts to loosen and the tire to fall off, result-ing in death or serious injury.
• Never apply oil or grease to the
wheel bolts or their contact surface
on the wheel .
Doing so may cause the wheel
bolts to be tightened excessively,
leading to damage to the wheel
bolts, the threaded portion the
wheel bolts install to , or the
wheel.
Also, the wheel bolts may come
loose, possibly leading to the wheel
coming off, causing a serious acci-
dent.
If oil or grease is attached to either
of these parts, remove it.
●When installing a wheel, use the
same wheel bolts that were removed with the wheel. Also, do not use any wheel bolts other than
Toyota genuine wheel bolts.
• If a wheel bolt hole in a wheel or the threads of a wheel bolt or the wheel hub are deformed, cracked, rusty or
otherwise damaged, have the vehi- cle inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
■When tightening the wheel bolts
Do not tighten the wheel bolts exces- sively.Doing so may cause the wheel bolts,
the threads of the wheel hub, or the wheel to be damaged.
■Replacing a flat tire for vehicles with power back door
In cases such as when replacing tires,
make sure to cancel the power back door system ( P.202). Failure to do so may cause the back door to oper-
ate unintentionally if the power back door switch is accidentally touched, resulting in hands and fingers being
caught and injured.

■Effects of incorrect tire inflation
pressure
Driving with incorrect tire inflation pres- sure may result in the following:
●Reduced electricity consumption effi-ciency
●Reduced driving comfort and poor handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating, have it checked by any authorized Toyota retailer or Toyota authorized repairer, or
any reliable repairer.
■Instructions for checking tire infla- tion pressure
When checking tire inflation pressure,
observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not been driven for more than 1.5 km or 1 mile, you
will get an accurate cold tire inflation pressure reading.
●Always use a tire pressure gauge.It is difficult to judge if a tire is properly inflated based only on its appearance.
●It is normal for the tire inflation pres-sure to be higher after driving as heat
is generated in the tire. Do not reduce tire inflation pressure after driving.
●Passengers and luggage weight
should be placed so that the vehicle is balanced.
Tire inflation pressure
Make sure to maintain proper
tire inflation pressure. Tire
inflation pressure should be
checked at least once per
month. However, Toyota rec-
ommends that tire inflation
pressure be checked once
every two weeks.
WARNING
■Proper inflation is critical to save
tire performance
Keep your tires properly inflated. If the tires are not properly inflated,
the following conditions may occur which could lead to an accident resulting in death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting from overheated tires
●Air leaking from between tire and wheel
●Wheel deformation and/or tire dam-age
●Greater possibility of tire damage while driving (due to road hazards, expansion joints, sharp edges in the
road, etc.)
NOTICE
■When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back
on. If a valve cap is not installed, dirt or moisture may get into the valve and
cause an air leak, resulting in decreased tire inflation pressure.

Maintenance and care
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 retailer or
Toyota authorized repairer, or any
reliable repairer.
*: 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
■When replacing wheels
The wheels of your vehicle 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.479)
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.
Wheel selection
WARNING
■When replacing wheels
●Do not use wheels that are a differ-
ent 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 leak-ing wheel which is designed for a
tubeless tire. Doing so may result in an accident, causing death or seri-ous injury.
■Wheel bolts
Observe the following precautions to
reduce the risk of death or serious injury:
●Do not over tighten.
●Never use oil or grease on the
wheel bolts. Oil and grease may cause the wheel bolts to be exces-sively tightened, leading to bolt or
disc wheel damage. In addition, the oil or grease can cause the wheel bolts to loosen and the wheel may
fall off, causing a serious accident. Remove any oil or grease from the wheel bolts.
●If there are any cracks or deforma-tions in the wheel bolts, or if the sur-
face treatment becomes worn, have the wheel bolts replaced at your any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer. Failure to follow these precautions could cause the
wheel bolts to loosen and the tire to fall off, resulting in death or serious injury.
■Use of defective wheels prohib-ited
Do not use cracked or deformed wheels.Doing so could cause the tire to leak
air during driving, possibly causing an accident.
