SAFETY AND EMERGENCY FEATURES
Keep as low on
hips as possible
Take up slack
Too high
Moving the lever to “LOCK” will allow the door to be opened only from
the outside\b
If belt is fully extended, then retracted even slightly, it cannot be
reextended beyond that point, unless fully retracted again\b This feature
is used to help hold child restraint systems securely\b
To find more information about seat belts, and how to install a child
restraint system, refer to theOwner’s Manual\b

If tire pressure becomes critically low on any of the tires (excluding the
spare), “ ” indicator will illuminate\b Correctly adjusting tire inflation
will turn off the light after a few minutes\b If the light does not turn off,
have the system checked by your Toyota dealer\b

Tires
Replace or rotate tires in accordance with maintenance sched-
ules and treadwear.
■Checking tires
New tread
Treadwear indicator
Worn tread
The location of treadwear
indicators is shown by the
“TWI” or “ ” marks, etc.,
molded on the sidewall of
each tire.
Check spare tire condition
and inflation pressure if not
rotated.
■Tire rotation
Rotate the tires in the order
shown.
To equalize tire wear and
extend tire life, Toyota recom-
mends that tire rotation is
carried out at the same inter-
val as tire inspection.
■The tire pressure warning system (if equipped)
Your Toyota is equipped with a tire pressure warning system that
uses tire pressure warning valves and transmitters to detect low
tire inflation pressure before serious problems arise.

252 4-3. Do-it-yourself maintenance
■If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
■Maximum load of tire
Check that the maximum load of the replacement tire is greater than 1/2
of the Gross Axle Weight Ratings (GAW R) of either the front axle or the
rear axle, whichever is greater.
■Tire types
1 Summer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Sinc e summer tires do not have the same
traction performance as snow tire s, summer tires are inadequate for
driving on snow-covered or icy roads. For driving on snow-covered
roads or icy roads, the use of snow tires is recommended. When
installing snow tires, be sure to replace all four tires.
2 All season tires All season tires are designed to provide better traction in snow and to
be adequate for driving in most winter conditions, as well as for use
year round. All season tires, however, do not have adequate traction
performance compared with snow tires in heavy or loose snow. Also,
all season tires fall short in acceleration and handling performance
compared with summer tires in highway driving.
3Snow tires
For driving on snow-covered roads or icy roads, we recommend using
snow tires. If you need snow tires, select tires of the same size, con-
struction and load capacity as the or iginally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires without
first checking local regulations for possible restriction. Snow tires
should be installed on all wheels. ( →P. 150)
For the GAWR, see the Certification
Label. For the maximum load of the
tire, see the load limit at maximum cold
tire inflation pressure mentioned on the
sidewall of the tire. (→ P. 3 5 2

Maintenance and care
■Routine tire inflation pressure checks
The tire pressure warning system doe
s not replace routine tire inflation
pressure checks. Make su re to check tire inflation pressure as part of
your routine of daily vehicle checks.
■Tire pressure warning system certification

Maintenance and care
NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps (vehicles with a tire pressure warn-
ing system)
●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 cor-
rectly.
●When replacing tire valve caps, do not use tire valve caps other than
those specified. The cap may become stuck.
■To avoid damaging the tire pressure warning valves and transmit-
ters (vehicles with a tire pressure warning system)
Do not use liquid sealants on flat tires.
■Driving on rough roads
Take particular care when driving
on roads with loose surfaces or pot-
holes.
These conditions may cause losses in tire inflation pressure, reducing
the cushioning ability of the tires. In addition driving on rough roads may
cause damage to the tires themselves, as well as the vehicle’s wheels
and body.
■If tire inflation pressures become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Inspection and adjustment procedure
Tire valve
Tire pressure gauge
Remove the tire valve cap.
Press the tip of the tire pressure gauge onto the tire valve.
Read the pressure using the graduations of the gauge.
If the tire inflation pressure is not within the recommended
levels, adjust inflate the tire.
If you add too much air, pres s the center of the valve to
lower.
After completing the tire inflation pressure measurement
and adjustment, apply soapy water to the valve and check
for leakage.
Reinstall the tire valve cap.
