Maintenance and care
NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps
● When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer as the tire press ure warning
valves and transmitters may be damaged if not handled correctly .
● Make sure to install the tire valve caps. If the tire valve caps are not
installed, water could enter the tire pressure warning valves a nd the tire
pressure warning valves could be bound.
● When replacing tire valve caps, do not use tire valve caps other than those
specified.
The cap may become stuck.
■ Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire inflation pressure, r educing the
cushioning ability of the tires. In addition, driving on rough roads may cause
damage to the tires themselves, as well as the vehicle’s wheels and body.
■ To avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid sealants, the tire pressure warning valve
and transmitter may not operate properly. If a liquid sealant i s used, contact
any authorized Toyota retailer or Toyota authorized repairer, o r any reliable
repairer or other qualified service shop as soon as possible. A fter use of liq-
uid sealant, make sure to replace the tire pressure warning val ve and trans-
mitter when repairing or replacing the tire. ( P. 616)
■ If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be rui ned.

Maintenance and care
WARNING
■Proper inflation is critical to save tire performance
Keep your tires properly inflated.
If the tires are not properly inflated, the following condition s may occur
which could lead to an accident resulting in death or serious i njury:
● 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 damage
● 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 pressu re.

Maintenance and care
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warn ing valves
and transmitters (except for compact spare tire) that allow the tire pressure
warning system to provide advance warning in the event of a los s in tire infla-
tion pressure. Whenever wheels are replaced, tire pressure warning valves
and transmitters must be installed. ( P. 616)
WARNING
■When replacing wheels
● Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may resu lt 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
● Be sure to install the wheel nuts with the tapered ends facing inward.
( P. 736) 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 dea th 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 tight ened,
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, caus ing an acci-
dent and resulting in death or serious injury. Remove any oil o r 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, possi bly causing an
accident.

NOTICE
■Replacing tire pressure warning valves and transmitters
● Because tire repair or replacement may affect the tire pressure warning
valves and transmitters, make sure to have tires serviced by an y autho-
rized Toyota retailer or Toyota authorized repairer, or any rel iable repairer
or other qualified service shop. In addition, make sure to purc hase your
tire pressure warning valves and transmitters at any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repaire r.
● Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work prop erly with
non-genuine wheels.

Maintenance and care
■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 batte ry (traction bat-
tery) becomes limited, the distance that the vehicle can be dri ven using the
electric motor (traction motor) may be reduced and the fuel eco nomy 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 any
authorized Toyota retailer or Toyota authorized repairer, or an y reliable
repairer.
■ If “Maintenance required for Traction battery cooling parts See owner’s
manual.” is shown on the multi-information display
● If this message is shown on the multi-information display, remove the air
intake vent cover and clean the filter. ( P. 638)
● After cleaning the air intake vent, start the hybrid system and check that the
warning message is no longer displayed.
After the hybrid system is started, it may be necessary to driv e the vehicle
up to approximately 20 minutes before the warning message disap pears. If
the warning message does not disappear after driving for approp riately 20
minutes, have the vehicle inspected by any authorized Toyota re tailer or
