The initialization operation
●Make sure to carry out initializ
ation after adjusting the tire inflation pres-
sure.
Also, make sure the tires are co ld before carrying out initialization or tire
inflation pressure adjustment.
●If you have accidentally turned the engine switch to the “LOCK” position
(vehicles without a smart key system) or off (vehicles with a s mart key
system) during initialization, it is not necessary to press the reset switch
again as initialization will rest art automatically when the engine switch
has been turned to the “ON” posi tion (vehicles without a smart key sys-
tem) or IGNITION ON mode (vehicl es with a smart key system) for the
next time.
●If you accidentally press the reset switch when initialization is not neces-
sary, adjust the tire inflation pressure to the specified level when the
tires are cold, and cond uct initialization again.
■When initialization of the tire pressure warning system has fai led
Initialization can be completed i n a few minutes. However, in the following
cases, the settings have not been record ed and the system will not oper-
ate properly. If repeated attempts to record tire inflation pre ssure settings
are unsuccessful, have the vehicl e inspected by your Toyota dealer.
●When operating the tire pressure warning reset switch, the tire pressure
warning light does not blink 3 times.
●After carrying out the initializ ation procedure, the tire press ure warning
light blinks for 1 minute then st ays on after driving for 20 minutes.

WARNING
■When inspecting or replacing tires
Observe the following precaut ions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as
dangerous handling characteristics, which may lead to an accide nt
resulting in death o r serious injury.
●Do not mix tires of different ma kes, models or tread patterns.
Also, do not mix tires of re markably different treadwear.
●Do not use tire sizes other th an those recommended by Toyota.
●Do not mix differently constructed tires (radial, bias-belted o r bias-ply
tires).
●Do not mix summer, all season and snow tires.
●Vehicles with a compact spare tire: Do not tow if your vehicle has a
compact spare tire installed.
■When initializing the tire pressure warning system
Do not operate the tire pressure warning reset switch without first
adjusting the tire inflation pressure to the specified level. O therwise, the
tire pressure warning light may not come on even if the tire in flation
pressure is low, or it may come on when the tire inflation pres sure is
actually normal.

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 your Toyota dealer as the tire pres-
sure warning valves and transmitters may be damaged if not hand led
correctly.
●Make sure to install the tire val ve caps. If the tire valve caps are not
installed, water could enter the tire pressure warning valves a nd the
tire pressure warning valves could be bound.
●When replacing tire valve caps, do not use tire valve caps othe r than
those specified. The cap may become stuck.
■To avoid damage to the tire pressure warning valves and transmi t-
ters
When a tire is repaired with liqui d sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sea lant is
used, contact your Toyota dealer or other qualified service shop as soon
as possible. Make sure to replac e the tire pressure warning valve and
transmitter when replacing the tire. ( P. 5 3 3 )
■Driving on rough roads
Take particular care when drivi ng on roads with loose surfaces or pot-
holes.
These conditions may cause losses in tire inflation pressure, reducing
the cushioning ability of the t ires. In addition, driving on ro ugh roads
may cause damage to the tires themselves, as well as the vehicl e’s
wheels and body.
■If tire inflation pressure of e ach tire becomes low while drivi ng
Do not continue driving, or your t ires and/or wheels may be ruined.

The recommended cold tire infla-
tion pressure and tire size are dis-
played on the tire and loading
information label. (P. 660)
Tire valve
Tire pressure gauge
Remove the tire valve cap.
Press the tip of the tire press ure gauge onto the tire valve.
Read the pressure using the gauge gradations.
If the tire inflation pressure is not at the recommended level, adjust
the pressure.
If you add too much air, press the center of the valve to defla te.
After completing the tire inflation pressure measurement and
adjustment, apply soapy water to the valve and check for leakage.
Put the tire valve cap back on.

■Tire inflation pressure check interval
You should check tire inflation pressure every two weeks, or at least once
a month.
Do not forget to check the spare.
■Effects of incorrect tire inflation pressure
Driving with incorrec t tire inflation pressure may result in th e 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 your Toyota dealer.
■Instructions for checking tire inflation pressure
When checking tire inflation p ressure, 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 mile or 1.5 km, 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 o nly 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 pre ssure after
driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehi cle is
balanced.

WARNING
■Proper inflation is critical to save tire performance
Keep your tires properly inflated.
If the tires are not properly in flated, the following conditions may occur
which could lead to an accident r esulting in death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting from overh eated 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 on the road, etc.)
NOTICE
■When inspecting and adjusti ng 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 pressu re.

When trouble arises
HIGHLANDER_U (OM0E031U)■
When a tire is replace
d with a spare tire
Vehicles with a compact spare tire
The compact spare tire is not equipped with a tire pressure war ning valve
and transmitter. If a tire goes flat, the tire pressure warning light will not
turn off even though the flat tire has been replaced with the s pare tire.
Replace the spare tire with the repaired tire and adjust the ti re inflation
pressure. The tire pressure war ning light will go off after a few minutes.
Vehicles with a full-size spare tire
The spare tire is also equipped with the tire pressure warning valve and
transmitter. The tire pressure warning light will turn on if the tire inflation
pressure of the spare tire is low. If a tire goes flat, even th ough the flat tire
is replaced with the spare tire, the tire pressure warning light does not
turn off. Replace the spare tire with the repaired tire and adj ust to the
proper tire inflation pressure. The tire pressure warning light will turn off
after a few minutes.
■Conditions that the tire pressure warning system may not functi on
properly
 P. 5 3 7
■If the tire pressure warning light frequently comes on after bl inking
for 1 minute
If the tire pressure warning light frequently comes on after bl inking for 1
minute when the engine switch is turned on, have it checked by your
Toyota dealer.
■ Customization that can be configured at Toyota dealer
The vehicle speed linked seat belt reminder buzzer can be disab led.
(Customizable features P. 690) However, Toyota recommends that the seat
belt reminder buzzer be operational to alert the driver and fro nt passenger
when seat belts are not fastened.

WARNING
■If both the ABS and the brake s ystem warning lights remain on
Stop your vehicle in a safe place immediately and contact your To y o t a
dealer. The vehicle will become extremely unstable during braki ng, and the
ABS system may fail, which could cause an accident resulting in death or
serious injury.
■ When the electric power steering system warning light comes on
The steering wheel may become extremely heavy.
When steering wheel operations are heavier than usual, grip the steering
wheel firmly and operate it using more force than usual.
■
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 t he tire
inflation pressure immediately.
●If the tire pressure warning light comes on even after tire inf lation pres-
sure adjustment, it is probable that you have a flat tire. Chec k the tires.
If a tire is flat, change it with the spare tire and have the f lat tire
repaired by the nearest Toyota dealer.
●Avoid abrupt maneuvering and braking. If the vehicle tires dete riorate,
you could lose control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.
