Check if the treadwear indicators are showing on the tires. Also check
the tires for uneven wear, such as excessive wear on one side of the
tread.
Check the spare tire condition and pressure if not rotated.

Treadwear indicator
The location of treadwear indicators is shown by a “TWI” or “Δ” mark,
etc., molded into the sidewall of each tire.

◆Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to register the ID code. Have the ID code
registered by your Toyota dealer.
■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric, and bulges indicating internal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the size
or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
■Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not reg-
istered, the tire pressure warning system will not work properly. After driv-
ing for about 20 minutes, the tire pressure warning light blinks for 1
minute and stays on to indicate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even
if it has seldom or never been used or damage is not obvious.
■Proper storage of the spare tire
As an improperly stored spare tire may cause damage to the wire cable
that holds it, check that the spare tire is stored properly on a daily basis.
• If the spare tire is slanted, the hoist assembly may be stuck in the wheel opening. If the spare tire rattles while driving, it may not be fully
raised. Lower the spare tire to the ground and make sure that the
hoist assembly is perpendic ular to the wheel opening.
• Raise the tire slowly and steadily until a click is heard and the jack handle skips.
• If the spare tire cannot be lowered, the wire cable may be severed.
Have the vehicle inspected at your Toyota dealer.
●If the stored spare tire is slanted or
causes a rattle while driving, properly
store the spare tire by following the
tire change procedure correctly
( → P. 597).

Situations in which the tire pressure warning system may not oper-
ate properly
●In the following cases, the tire pr
essure warning system may not operate
properly.
• If non-genuine Toyota wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equip- ment) tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are equipped.
• An auxiliary-supported run- flat tire is equipped.
• 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 the tire inflation pressure is extremely higher than the specified level.
• If the spare tire is in a location subject to poor radio wave signal
reception.
*
• If a large metallic object which ca n interfere with signal reception is
put in the luggage compartment.
*

: Vehicles with a full- size spare tire only
●Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large
display, airport or other facility that generates strong radio waves or
electrical noise
• When carrying a portable radio, cellular phone, cordless phone or
other wireless communication device
●When the vehicle is parked, the time taken for the warning to start or go
off could be extended.
●When tire inflation pressure declines rapidly for example when a tire has
burst, the warning may not function.

When trouble arises
HIGHLANDER_HV_U (OM48F12U)
WARNING
■Replacing a flat tire for vehicles with power back door
In cases such as when replacing tires, make sure to turn off the power
back door main switch ( →P. 133). Failure to do so may cause the back
door to operate unintentionally if the power back door switch is acciden-
tally touched, resulting in hands and fingers being caught and injured.
■After using the tools and jack
Before driving, make sure all the tools and jack are securely in place in
their storage location to reduce the po ssibility of personal injury during a
collision or sudden braking.
NOTICE
■Be careful when driving over bumps with the compact spare tire
installed on the vehicle.
The vehicle becomes lower when driving with the compact spare tire
compared to when driving with standa rd tires. Be careful when driving
over uneven road surfaces.
■Driving with tire chains and the compact spare tire
Do not fit tire chains to the compact spare tire.
Tire chains may damage the vehicle body and adversely affect driving
performance.
■When replacing the tires
When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact your Toyota dealer as the tire pressure
warning valve and transmitter may be damaged if not handled correctly.
■To avoid damage to the tire pressure warning valves and transmit-
ters
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 your Toyota dealer or other qualified service shop as soon
as possible. Make sure to replace the tire pressure warning valve and
transmitter when replacing the tire. ( →P. 524)

HIGHLANDER_HV_U (OM48F12U)
NOTICE
■When stowing the flat tire
●Ensure that there is no object caught between the tire and the vehicle
underbody.
●Securely tighten the spare tire clam p bolt to hold the spare wheel car-
rier by the hook.
●Stow the flat tire in the spare tire location. Failure to do so may cause
damage to the spare tire carrier. Proper storage redu ces the possibility
of injury in a collision or during sudden braking.
●Have the flat tire repaired and the spare tire replaced with it as soon as
possible.
■Proper storage of the spare tire
●Do not attempt to turn the spare tire clamp bolt without a tire on the
hoist assembly, as doing so may cause the wire cable to slip off of the
shaft inside the unit and the wire cable may not be able to be raised or
lowered. If the spare tire clamp bolt has been turned without a tire on
the hoist assembly and the wire cable cannot be raised or lowered,
contact your Toyota dealer.
●If the hoist assembly is slanted when
stowing a tire, the hoist assembly may
become stuck in the wheel opening
and the tire may not be raised prop-
erly, causing damage to the wheel or
the wire cable.

Tire ply composition and materials
Plies are layers of rubber-coated parallel cords. Cords are the strands
which form the plies in a tire.
Radial tires or bias-ply tires
A radial tire has “RADIAL” on the sidewall. A tire not marked “RADIAL”
is a bias-ply tire.
TUBELESS or TUBE TYPE
A tubeless tire does not have a tube and air is directly put into the tire.
A tube type tire has a tube inside the tire and the tube maintains the air
pressure.
Load limit at maximum cold tire inflation pressure ( →P. 660)
Maximum cold tire inflation pressure (→ P. 660)
This means the pressure to which a tire may be inflated.
Uniform tire quality grading
For details, see “Uniform Tire Quality Grading” that follows.
Summer tires or all season tires (→ P. 527)
An all season tire has “M+S” on the sidewall. A tire not marked “M+S”
is a summer tire.
“TEMPORARY USE ONLY”
A compact spare tire is identified by the phrase “TEMPORARY USE
ONLY” molded on its sidewall. This tire is designed for temporary
emergency use only.
