●When tire inflation pressure declines rapidly for example when a tire has
burst, the warning may not function.
■Warning performance of the tire pressure warning system
The warning of the tire pressure warning
system will change in accordance with the conditions under which it was initial-ized. For this reason, the system may
give a warning even if the tire pressure does not reach a low enough level, or if the pressure is higher than the pressure
that was adjusted to when the system was initialized.
When replacing tires or wheels, tire
pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure warn-
ing computer and the tire pressure
warning system must be initialized.
( P.495)
■When replacing the tires and
wheels
If the ID code of the tire pressure warn- ing valve and transmitter is not regis-
tered, the tire pressure warning system will not work properly. After driving for about 10 minutes, the tire pressure
warning light blinks for 1 minute and stays on to indicate a system malfunc-tion.

ing valves and transmitters
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 pressure 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 and 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.
■To avoid damage to the tire pres-sure warning valves and trans-mitters (vehicles without spare
tire)
When a tire is repaired with liquid sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sealant is used, contact any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer or other qualified ser-vice shop as soon as possible. After
use of liquid sealant, make sure to replace the tire pressure warning valve and transmitter when repairing
or replacing the tire. ( P.491)

■The tire pressure warning sys-
tem must be initialized in the
following circumstances:
When rotating the tires.
When changing the tire.
After registering the ID codes.
(P.495)
When changing between two
registered wheel sets.
When the tire pressure warning
system is initialized, the current tire
inflation pressure is set as the
benchmark pressure.
■How to initialize the tire pres-
sure warning system (with 7-
inch display)
1Park the vehicle in a safe place
and stop the hybrid system for
20 minutes or more.
Initialization cannot be performed while
the vehicle is moving.
2Adjust the tire inflation pressure
to the specified cold tire inflation
pressure level. (P.590)
Make sure to adjust the tire pressure to

ing for 1 hour or more, park the vehicle
in a safe place for approximately 20
minutes and then drive the vehicle
again.
■When initializing
●Initialization is performed while driving
at a vehicle speed of approximately
40 km/h (25 mph) or more.
●Make sure to carry out initialization
after adjusting the tire inflation pres-
sure. Also, make sure the tires are
cold before carrying out initialization
or tire inflation pressure adjustment.
●The tire pressure warning system can
be initialized by yourself, but depend-
ing on the driving conditions and driv-
ing environment, initialization may
take some time to complete.
■The initialization operation
●If you have accidentally turned the
power switch to OFF during initializa-
tion, it is not necessary to restart the
initialization again as initialization will
restart automatically when the power
switch has been turned to ON for the
next time.
●If you accidentally perform initializa-
tion when initialization is not neces-
sary, adjust the tire inflation pressure
to the specified level when the tires
are cold, and conduct initialization
again.
●While the position of each tire is being
determined and the inflation pres-
sures are not being displayed on the
multi-information display, if the infla-
tion pressure of a tire drops, the tire
pressure warning light will come on.
■If the tire pressure warning system
is not initialized properly
●In the following situations, initialization
may take longer than usual to be com-
pleted or may not be possible. Nor-
mally, initialization completes within
approximately 30 minutes.
• Vehicle is not driven at approximately
40 km/h (25 mph) or more• Vehicle is driven on unpaved roads
• Vehicle is driven near other vehicles
and system cannot recognize tire
pressure warning valve and transmit-
ters of your vehicle over those of other
vehicles.
• If the vehicle is driven in heavy traffic
or another situation where other vehi-
cles are driven close by, it may take
time for the system to recognize the
tire pressure warning valve and trans-
mitters of your vehicle over those of
other vehicles.
●If initialization does not complete after
driving for 1 hour or more, park the
vehicle in a safe place for approxi-
mately 20 minutes and then drive the
vehicle again.
●If the vehicle is reversed during initial-
ization, the data up to that point is
reset, so perform the initialization pro-
cedure again from the beginning.
●In the following situations, initialization
will not be started or was not com-
pleted properly and the system will not
operate properly. Perform the initial-
ization procedure again.
• If, when attempting to start initializa-
tion, the tire pressure warning light
does not blink 3 times.
• If, when the vehicle has been driven
for about 20 minutes after performing
initialization, the tire pressure warning
light blinks for approximately 1 minute
and then illuminates.
If initialization cannot be completed after
performing the above procedure, con-
tact any authorized Toyota retailer or
Toyota authorized repairer, or any reli-
able repairer.

4987-3. Do-it-yourself maintenance
■Effects of incorrect tire inflation
pressure
Driving with incorrect tire inflation pres- sure 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 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.Tire inflation pressure
Make sure to maintain the
proper tire inflation pressure.
Tire inflation pressure should
be checked at least once per
month. However, Toyota rec-
ommends that tire inflation
pressure be checked once
every two weeks. ( P.590)
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 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.
5007-3. Do-it-yourself maintenance
Use only Toyota wheel nuts and
wrenches designed for use with

■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 pur-chase 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.

Removal method
5308-2. Steps to take in an emergency
When using a flat-bed truck to
transport the vehicle, use tire strap-
ping belts. Refer to the owner’s
manual of the flat-bed truck for the
tire strapping method.
In order to suppress vehicle move-
ment during transportation, set the
parking brake and turn the power
switch off.
If a tow truck is not available in an
emergency, your vehicle may be
temporarily towed using cables or
chains secured to the emergency
towing eyelets. This should only be
attempted on hard surfaced roads
for short distances at under 30
km/h (18 mph).
A driver must be in the vehicle to
steer and operate the brakes. The
vehicle’s wheels, drive train, axles,
steering and brakes must be in
good condition.
WARNING
■When towing the vehicle
Be sure to transport the vehicle with
all four wheels raised off the ground. If the vehicle is towed with the tires contacting the ground, the drivetrain
or related parts may be damaged, the vehicle may fly off the truck, or elec-tricity generated by the operation of
the motor may cause a fire to occur depending on the nature of the dam-age or malfunction.
NOTICE
■To prevent damage to the vehicle when towing using a wheel-lift type truck
●Do not tow the vehicle from the rear when the power switch is off. The steering lock mechanism (if
equipped) is not strong enough to hold the front wheels straight.
●When raising the vehicle, ensure adequate ground clearance for tow-ing at the opposite end of the raised
vehicle. Without adequate clear- ance, the vehicle could be dam-aged while being towed.
■Towing with a sling-type truck
Do not tow with a sling-type truck to prevent body damage.
