Maintenance and care
Tire inflation pressure
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
●Reduced fuel economy
●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 inflation 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 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.
●Passengers and luggage weight should be placed so that the vehicle is bal-
anced.
Make sure to maintain proper tire inflation pressure. Tire infla-
tion pressure should be checked at least once per month. How-
ever, Toyota recommends that tire inflation pressure be checked
once every two weeks. (P. 779)

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 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 pressure.

Maintenance and care
Wheels
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
●Use only Toyota wheel nuts and 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 balancing your 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.

■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. 651)
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 tube-
less tire. Doing so may result in an accident, causing death or serious
injury.
■ When installing the wheel nuts
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
● 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
or other qualified service shop. In addition, make sure to purchase your
tire pressure warning 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.

Maintenance and care
WARNING
■ Using the tire jack
Observe the following precautions.
Improper use of the tire jack may cause the vehicle to suddenly fall off the
jack, leading to death or serious injury.
● Only use the tire jack that comes with this vehicle for replacing a tire.
Do not use it on other vehicles, and do not use other tire jacks for replac-
ing tires on this vehicle.
● Do not raise the vehicle while someone is inside.
● Do not use the tire jack for any purpose other than replacing tires or install-
ing and removing tire chains.
● Do not put any part of your body under the vehicle while it is supported by
the jack.
● Do not start the hybrid system or drive the vehicle while the vehicle is sup-
ported by the jack.
● When raising the vehicle, do not put an object on or under the jack.
● Do not raise the vehicle to a height greater than that required to replace
the tire.
● Use a jack stand if it is necessary to get under the vehicle.
● When lowering the vehicle, make sure that there is no-one near the vehi-
cle. If there are people nearby, warn them vocally before lowering.
■ When removing the jack from the storage location
The jack may be hot due to heat from the charging equipment during or
after charging. Please use gloves when handling the jack. If it is touched
with bare hands, it may result in burns.
● Put the jack properly in its jack point.
