Tire valve

Tire pressure gauge

Remove the tire valve cap.

Press the tip of the tire pres-
sure 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
deflate.

After completing the tire infla-
tion 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 pres-

sure 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 pres-

sure, 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

appearance.

●

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 pressure

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

inflated, the following conditions

may occur which could lead to an

accident resulting in death or seri-

ous 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

damage

●

Greater possibility of tire dam-

age while driving (due to road

hazards, expansion joints,

sharp edges in the road, etc.)

NOTICE

■

When inspecting and adjust-

ing 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.

When replacing wheels, care
should be taken to ensure that
they are equivalent to those
removed in load capacity, diam-
eter, rim width and inset

Replacement wheels are avail-
able at your Toyota dealer.

: Conventionally referred to as off-

set.

Toyota does not recommend
using the following:



Wheels of different sizes or
types



Used wheels



Bent wheels that have been
straightened

■

When replacing wheels (vehi-

cles with a tire pressure warn-

ing system)

The wheels of your vehicle are

equipped with tire pressure warning

valves and transmitters that allow

the tire pressure warning system to

provide advance warning in the

event of a loss in tire inflation pres-

sure. Whenever wheels are

replaced, the tire pressure warning

valves and transmitters must be

installed. (



P.473)

Wheels

If a wheel is bent, cracked or
heavily corroded, it should
be replaced. Otherwise, the
tire may separate from the
wheel or cause a loss of
handling control.

Wheel selection

WARNING

■

When replacing wheels

●

Do not use wheels that are a dif-

ferent size from those recom-

mended in the Owner’s Manual,

as this may result in a loss of

handling control.

●

Never use an inner tube in a

leaking wheel which is designed

for a tubeless tire.

Doing so may result in an acci-

dent, causing death or serious

injury.

■

When installing the wheel

nuts

●

Be sure to install the wheel nuts

with the tapered ends facing

inward.(P.534) Installing the

nuts with the tapered ends fac-

ing outward can cause the

wheel to break and eventually

cause the wheel to come off

while driving, which could lead

to an accident resulting in death

or serious injury.

●

Never use oil or grease on the

wheel bolts or wheel nuts.

Oil and grease may cause the

wheel nuts to be excessively

tightened, leading to bolt or disc

wheel damage. In addition, the

oil or grease can cause the

wheel nuts to loosen and the

wheel may fall off, causing an

accident and resulting in death

or serious injury. Remove any

oil or grease from the wheel

bolts or wheel nuts.

■

Use of defective wheels pro-

hibited

Do not use cracked or deformed

wheels. Doing so could cause the

tire to leak air during driving, pos-

sibly causing an accident.

LED light bulbs

The lights other than the front turn

signal lights/parking lights (vehicles

without side turn signal lights), front

lights, rear side marker lights (bulb

type) and back-up lights consist of a

number of LEDs. If any of the LEDs

Toyota dealer to have the light

replaced.

■

Condensation build-up on the

inside of the lens

In certain situations, such as when

driving in the rain or when washing

the vehicle, condensation may form

on the inner side of the headlight

lens and other lights. As each light

has a ventilation hole, moist air may

enter. If the ambient temperature is

low, condensation may form tempo-

rarily, but it will dissipate as the

inside of the light is warmed up. As

the condensation is due to a phe-

nomenon similar to windows fogging

in the rain, it does not indicate a

malfunction.
Contact your Toyota dealer for more

information in the following situa-

tions:

●

Large drops of water have built up

on the inside of the lens.
