Instructions for checking tire pressure

When checking tire 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 appear-

ance.

⚫

It is normal for the tire inflation pressure to be higher after driving as heat is
generated in the tire. Do not reduce tire inflation pressure after driving.

⚫

When loading luggage or driving with many occupants, do not apply the
load unevenly

WARNING

⬛

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 tubeless
tire. Doing so may result in an accident, causing death or serious injury.

⬛

When installing the wheel nuts

⚫

Be sure to install the wheel nuts with the tapered ends facing inward.
(

➞

P. 402) 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.

⚫

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, causing 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 prohibited

Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing an

accident.

NOTICE

⬛

Replacing tire pressure warning valves and transmitters (vehicles with a 
tire pressure warning system)

⚫

Because tire repair or replacement may affect the tire pressure 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 transmitters at your Toyota dealer.

⚫

Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly with

non-genuine wheels.
