Maintenance and care
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pres- sure may result in the following:
●Reduced safety
●Damage to the drivetrain
●Reduced tire life due to wear
●Reduced fuel economy
●Reduced driving comfort and poor
handling
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.
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 on 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.

6-3. Do-it-yourself maintenance
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, the tire pressure warning valves and transmitters must be
installed. ( P.336)
■When removing the wheel orna-
ment (vehicles with a wheel cap clip)
Remove the wheel ornament using the
wheel cap clip*.*: The wheel cap clip is installed in the
glove box. ( P.298)
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 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.

6-3. Do-it-yourself maintenance
Maintenance and care
Use only Toyota wheel nuts and
wheel nut 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 bal-
ancing your wheels.
WARNING
●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,
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 prohib-
ited
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
●Because tire repair or replacement
may affect the tire pressure warning valves and transmitters, make sure to have tires serviced by any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer. In addition, make sure to
purchase your tire pressure warn- ing valves and transmitters at any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
●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.

Refer to “Toyota Service Booklet” or “Toyota Warranty Booklet”.
■Cleaning the air intake vent
●Dust in the air intake vent may inter-fere with the cooling of the hybrid bat-
tery (traction battery). If charging/discharging of the hybrid battery (traction battery) becomes lim-
ited, 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
damage to them. If you have any con- cerns about cleaning the filter, contact any authorized Toyota retailer or
Toyota authorized repairer, or any reli- able repairer.
■If “Maintenance Required for Trac-tion Battery Cooling Parts See
Owner’s Manual” is displayed on the multi-information display
●If this warning message is displayed on the multi-information display, remove the air intake vent cover and

clean the filter. ( P.348)
●After cleaning the air intake vent, start the hybrid system and check that the
warning message is no longer dis- played.After the hybrid system is started, it
may be necessary to drive the vehicle up to approximately 20 minutes before the warning message disappears. If
the warning message does not disap- pear after driving for appropriately 20 minutes, have the vehicle inspected
by any authorized Toyota retailer or Toyota authorized repairer, or any reli-able repairer.
WARNING
■When cleaning the air intake vent
●Do not use water or other liquids to clean the air intake vent. If water is
applied to the hybrid battery (trac- tion battery) or other components, a malfunction or fire may occur.
●Before cleaning the air intake vent, make sure to turn the power switch
off to stop the hybrid system.
■When removing the air intake
vent cover
Do not touch the service plug located near the air intake vent. ( P.80)
NOTICE
■When cleaning the air intake vent
When cleaning the air intake vent,
make sure to only use a vacuum to suck out dust and clogs. If a com-pressed air blow gun, etc. is used to
blow out dust and clogs, the dust or clogs may be pushed into the air intake vent, which may affect the per-
formance of the hybrid battery (trac- tion battery) and cause a malfunction.
■To prevent damage to the vehicle
●Do not allow water or foreign matter to enter the air intake vent when the
cover is removed.
●Carefully handle the removed filter
so that it will not be damaged. If the filter is damaged, have it replaced with a new filter by any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Make sure to reinstall the filter and cover to their original positions after
cleaning.
