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 seri-

ous injury.

■

When installing the wheel nuts

●

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

(



P. 521) 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 seri-

ous 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 an

accident and resulting in death or serious injury. Remove any oil or

grease from the wheel bolts or wheel nuts.

NOTICE

■

Replacing tire pressure warning valve and transmitters

●

Because tire repair or replacement may affect the tire pressure warn-
ing valve 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 valve and transmitters at your
Toyota dealer.

●

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

larly. For details, refer to “Scheduled Maintenance Guide” or “Owner’s Man-
ual Supplement”.

■

Cleaning the air intake vent

●

Dust in the air intake vent may interfere with the cooling of the hybrid battery
(traction battery). If charging/discharging of the hybrid battery (traction bat-
tery) becomes limited, the distance that the vehicle can be driven using the
electric motor (traction motor) may be reduced and the fuel economy may
be reduced.
Inspect and clean the air intake vent periodically.

●

Improper handling of the air intake vent cover and filter may result in dam-
age to them. If you have any concerns about cleaning the filter, contact your
Toyota dealer.
