Maintenance and care
HIGHLANDER_HV_U (OM48F12U)
■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 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 your Toyota dealer.
■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 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 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 no t reduce tire inflation pressure after
driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is
balanced.

Tire pressure warning lightWhen the light comes on:
Low tire inflation pressure such as
• Natural causes ( →P. 572)
• Flat tire ( →P. 597)
→ Adjust the tire inflation pressure (including the
full-size spare tire) to the specified level.
The light will turn off af ter a few minutes. In case
the light does not turn off even if the tire inflation
pressure is adjusted, have the system checked by
your Toyota dealer.
When the light comes on after blinking for 1 minute:
Malfunction in the tire pressure warning system
( → P. 573)
→ Have the system checked by your Toyota dealer.
Vehicle proximity notification system warning light
This warning light flashes then stays on to indicate that
there is a malfunction in the vehicle proximity notification
system.
→ Have the vehicle inspected by your Toyota dealer
immediately.

When a tire is replaced with a spare tire
Vehicles with a compact spare tire
The compact spare tire is not equipped with a tire pressure warning valve
and transmitter. If a tire goes flat, the tire pressure warning light will not
turn off even though the flat tire ha s been replaced with the spare tire.
Replace the spare tire with the repair ed tire and adjust the tire inflation
pressure. The tire pressu re warning 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 pres sure warning light will turn on if the tire inflation
pressure of the spare tire is low. If a tire goes flat, even though 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 adjust to the
proper tire inflatio n pressure. The tire pressure warning light will turn off
after a few minutes.
■Conditions that the tire pressure warning system may not function
properly
→ P. 5 2 8
■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 power switch is turn ed to ON mode, have it checked 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. 675) However, Toyota recommends that the seat
belt reminder buzzer be operational to alert the driver and front passenger
when seat belts are not fastened.
■ Warning buzzer
In some cases, the buzzer may not be heard because of noisy place or an
audio sound.

WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact your Toyota
dealer. The vehicle will become extremely unstable during braking, and the
ABS system may fail, which could cause an accident resulting in death or
serious injury.
■ When the electric power steerin g 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 the tire
inflation pressure immediately.
●If the tire pressure warning light co mes on even after tire inflation pres-
sure adjustment, it is probable that you have a flat tire. Check the tires.
If a tire is flat, change it with the 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 system may not activate immediately.

WARNING
■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 dif-
ferent 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 pressure 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 pre ssure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale (tire pressure 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, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-inflation has not reached
the level to trigger illumination of the TPMS low tire pressure telltale (tire
pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warn-
ing system) malfunction indicator to indicate when the system is not
operating properly. The TPMS (tire pressure warning system) malfunc-
tion indicator is combined with the lo w tire pressure telltale (tire pressure
warning light). When the system detects a malfunction, the telltale will
flash for approximately one minute and then remain continuously illumi-
nated. This sequence w ill continue upon subsequ ent vehicle start-ups
as long as the malfunction exists. When the malfunction indicator is illu-
minated, the system may not be able to detect or signal low tire pres-
sure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installation of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure warning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction te lltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS (tire pressure warning system) to
continue to function properly.

●Stop the vehicle in a safe pl ace on a hard, flat surface.
● Set the parking brake.
● Shift the shift lever to P.
● Stop the hybrid system.
● Turn on the emergency flashers. ( →P. 560)
If you have a flat tire
Your vehicle is equipped with a spare tire. The flat tire can be
replaced with the spare tire.

WARNING
■If you have a flat tire
Do not continue driving with a flat tire.
Driving even a short dist ance with a flat tire can damage the tire and the
wheel beyond repair, which could result in an accident.
