■If the tire pressure warning system is not functioning
The tire pressure warning system will be disabled in the following condi-
tions:
(When the condition be
comes normal, the system will work properly.)
●If tires not equipped with tire pressure warning valves and transmit-
ters are used
●If the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure warning computer
●If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or
higher
The tire pressure warning system may be disabled in the following condi-
tions:
(When the condition be comes normal, the system will work properly.)
●If electronic devices or facilities using similar radio wave frequencies
are nearby
●If a radio set at a similar frequency is in use in the vehicle
●If a window tint that affects the radio wave signals is installed
●If there is a lot of snow or ice on the vehicle, particularly around the
wheels or wheel housings
●If non-genuine Toyota wheels are used (Even if you use Toyota
wheels, the tire pressure warning system may not work properly with
some types of tires.)
●If tire chains are used
■If the tire pressure warning light frequently comes on after blinking
for 1 minute
If the tire pressure warning light frequently comes on after blinking for 1
minute when the “ENGINE START STOP ” switch (vehicles with a smart
key system) or the engine switch (veh icles without a smart key system)
is turned on, have it che cked by your Toyota dealer.
■Customization that can be co nfigured at Toyota dealer
The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features P. 664) However, Toyota recommends that the
seat belt reminder buzzer be operational to alert the driver and front passen-
ger when seat belts are not fastened.

CAUTION
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could
cause a loss of vehicle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire
inflation pressure immediately.
●If the tire pressure warning light comes on even after tire inflation pres-
sure adjustment, it is pr obable that you have a flat tire. Check the tires.
If a tire is flat, change it with th e spare tire and have the flat tire
repaired by the nearest Toyota dealer.
●Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate,
you could lose control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning syste m may not activate immediately.

CAUTION
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle
placard or tire inflation pressure
label (tire and load information label). (If your vehicle has tires of a differ-
ent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine the
proper tire inflation pr essure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS-ti re pressure warning system) that
illuminates a low tire pressure telltal e (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale (tire pre ssure warning light) illumi-
nates, you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel effi ciency and tire tread life, and may
affect the vehicle's hand ling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper ti re maintenance, an d it is the driver's responsibility to
maintain correct tire pressure, even if under-inflation has not reached the
level to trigger illu mination of the TPMS low tire pressure telltale (tire
pressure warning light).

If you have a flat tire
Remove the flat tire and replace it with the spare tire provided.
■Before jacking up the vehicle
●Stop the vehicle on a hard, flat surface.
● Set the parking brake.
● Shift the shift lever to P.
● Stop the engine.
● Turn on the emergency flashers.

Replacing a flat tire
Chock the tires.
Remove the wheel ornament
using the wheel ornament
remover.
To protect the wheel ornament,
place a rag between the wheel
ornament remover and the
wheel ornament, as shown in
the illustration.

Stowing the flat/spare tire, jack and toolsLay down the tire with the outer
side facing up, and install the
holding bracket.
Insert the holding bracket tab into
one of the holes in the wheel.
Raise the tire.
Vehicles with kinetic dynamic suspension: Pull the tire toward
the rear of the vehicle when raising. After raising, visually
check that tire is not interfering with components.
Stow the tools and jack securely, and replace the cover.

STEP 1
■After completing the tire change
The tire pressure warnin g system must be reset. ( P. 543)
■When using the spare tire
As the spare tire is not equipped with a tire pressure warning valve and
transmitter, low inflation pressure of the spare tire will not be indicated by
the tire pressure warning system. Also, if you replace the spare tire after
the tire pressure warning light comes on, the light remains on.

CAUTION
■Using the tire jack
Improper use of the tire jack may cause the vehicle to suddenly fall off the
jack, leading to death or serious injury.
●
Do not use the tire jack for any pu
rpose other than replacing tires or
installing and removing tire chains.
●Only use the tire jack that comes wi th this vehicle for replacing a flat
tire.
Do not use it on other vehicles, and do not use other tire jacks for
replacing tires on this vehicle.
●Always check that the tire jack is securely set to the jack point.
●Do not put any part of your body under the vehicle while it is supported
by the jack.
●Do not start or run the engine while your vehicle is supported by the
jack.
●Do not raise the vehicle while someone is inside.
●When raising the vehicle, do not put an object on or under the jack.
●Do not raise the vehicle to a hei ght greater than that required to
replace the tire.
●Use a jack stand if it is necessary to get under the vehicle.
Vehicles with Automatic running boards
● Observe the following precautions. Failure to do so may result in serious
injury:
•
When jacking up the vehicle, always turn the Automatic running
boards switch off.
•When jacking up the vehicle, do not use an Automatic running
board as a jack point. The Automatic running board may break,
causing injuries.
Take particular care when lowering the vehicle to ensure that no one
working on or near the vehicle may be injured.

CAUTION
■Using the jack handle
Tighten all the jack handle bolts securely using a Phillips-head screw-
driver, to prevent the extension parts from coming apart unexpectedly.
■Replacing a flat tire
●Observe the following precautions.
Failure to do so may result in serious injury:
• Lower the spare tire completely to the ground before removing it from
under the vehicle.
• Do not try to remove the wheel ornament by hand. Take due care in handling the ornament to avoid unexpected personal injury.
• Do not attach a heavily damaged wheel ornament, as it may fly off the wheel while the vehicle is moving.
• Do not touch the disc wheels or the area around the brakes immedi- ately after the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around
the brakes will be extremely hot. Touching these areas with hands, feet
or other body parts while changing a tire, etc. may result in burns.
● Failure to follow these precautions could cause the wheel nuts to loosen
and the tire to fall off, resulting in death or serious injury.
• Have the wheel nuts tightened with a torque wrench to 81 ft•lbf (110
N•m, 11.2 kgf•m) as soon as possible after changing wheels.
• When installing a tire, only use wheel nuts that have been specifically designed for that wheel.
• If there are any cracks or deformations in the bolt screws, nut threads or bolt holes of the wheel, have the vehicle inspected by your Toyota
dealer.
• When installing the wheel nuts, be sure to install them with the tapered ends facing inward. ( P. 553)
