The following instructions for
checking tire inflation pressure
should be observed: The pressure s hould be
checked only when the tires are
cold. If your vehicle has been
parked for at least 3 hours and has
not been driven for more than 1.5
km or 1 mile since, you will get
an accurate cold tire inflation pres-
sure reading.
Always use a tire pressure
gauge. The appearance of a tire
can be misleading. Besides, tire
inflation pressures that are even
just a few pounds off can degrade
ride and handling.
Take special care when adding
air to the compact spare tire.
The smaller tire size can gain
pressure very qu ickly. Add com-
pressed air in small quantities and
check the pressure often until it
reaches the specified pressure.
Do not bleed or reduce tire
inflation pressure after driving.
It is normal for the tire inflation
pressure to be higher after driving.
Never exceed the vehicle capac-
ity weight. The passenger and
luggage weight should be located
so that the vehicle is balanced.Tire pressure gauge
INSPECTION AND ADJUSTMENT
PROCEDURE 1. Remove the tire valve cap.
2. Press the tip of the tire pressure gauge to the tire valve.
3. Read the pressure using a gradua- tion of the gauge.
4. In case that the tire inflation pres- sure is not within the prescribed
range, insert the compressed air
from the valve. In case of applying
too much air, press the center of
t he valv e and releas e the air to ad-
just.

The effectiveness of snow tires is
lost if the tread wears down below
4 mm (0.16 in.).
If you have tire damage such as
cuts, splits, cracks deep enough to
expose the fabric, or bulges indi-
cating internal damage, the tire
should be repl aced.
If a tire often goes flat or cannot be
properly repaired due to the size or
location of a cut or other damage, it
should be replaced. If you are not
sure, consult with your Toyota dealer.
If an air loss occurs while driving, do
not continue driving with a deflated
tire. Driving even a short distance can
damage a tire beyond repair. An y ti res wh i ch are over 6 years
old must be checked by a qualified
technician even if damage is not
obvious.
Tires deteriorate with age even if they
have never or seldom been used.
This applies also to the spare tire and
tires stored for future use.
REPLACING YOUR TIRES
When replacing a tire, use a tire of
the same size and construction,
and the same or greater maximum
load as the originally installed
tires.
Using any other size or type of tire
may seriously affect handling, ride,
speedometer/odometer calibration,
ground clearance, and clearance be-
tween the body and tires or snow
chains.
Check that the maximum load of the
replaced tire is greater than 1/2 of the
Gross Axle Weight Ratings (GAWR)
of either the front axle or the rear
axle, whichever greater. As for the
maximum load of the tire, see the load
limit at maximum cold tire inflation
pressure mentioned on the sidewall
of the tire, and as for the Gross Axle
Weight Ratings (GAWR), see the Cer-
tification Label.
For details about the side wall of the
tire and the Certification Label.

Without directional tires (with a
spare tire of the same wheel
type as the installed tires)Others
To equalize the wear and help ex-
tend tire life, Toyota recommends
that you rotate your tires accord-
ing to the maintenance schedule.
(For scheduled maintenance infor-
mation, please refer to the “Sched-
uled Maintenance Guide” or “Own-
er’s Manual Supplement”.)
However, the most appropriate tim-
ing for tire rotation may vary ac-
cording to your driving habits and
road surface conditions. See “If you have a fl
at tire” in Section
4 for tire change procedure.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out −
of −balance wheels, or severe braking.
CAUTION
Do not include a compact spare
tire when rotating the tires. It is
designed for temporary use only.

CAUTION
Do not exceed 50 km/h (30 mph) or
the chain manufacturer ’s recom-
mended speed limit, whichever is
lower.
Drive carefully avoiding bumps,
holes, and sharp turns, which may
cause the vehicle to bounce.
Avoid sharp turns or locked wheel
braking, as use of chains may ad-
versely affect vehicle handling.
When driving with chains installed,
be sure to drive carefully. Slow
down before entering curves to
avoid losing control of the vehicle.
Otherwise an accident may occur.
NOTICE
Do not attempt to use a tire chain on
the compact spare tire, as it may re-
sult in damage to the vehicle as well
as the tire.
WHEN TO REPLACE YOUR WHEELS
If you have wheel damage such as
bending, cracks or heavy corrosion, the
wheel should be replaced.
If you fail to replace a damaged wheel,
the tire may slip off the wheel or cause
loss of handling control.
WHEEL SELECTION
When replacing wheels, care should be
taken to ensure that the wheels are re-
placed by ones with the same load ca-
pacity, diameter, rim width, and offset.
This must be observed on compact spare
tires, too.
Correct replacement wheels are available
at your Toyota dealer.
A wheel of a different size or type may
adversely affect handling, wheel and bear-
ing life, brake cooling, speedometer/odom-
eter calibration, stopping ability, headlight
aim, bumper height, vehicle ground clear-
ance, and tire or snow chain clearance to
the body and chassis.Replacement with used wheels is not rec-
ommended as they may have been sub-
jected to rough treatment or high mileage
and could fail without warning. Also, bent
wheels which have been straightened may
have structural damage and therefore
should not be used. Never use an inner
tube in a leaking wheel which is designed
for a tubeless tire.
CAUTION
Do not use wheels other than the
manufacturer ’s recommended size, as
this may cause dangerous handling
characteristics resulting in loss of
control. Otherwise, an accident may
occur resulting in death or serious
injuries.
