■

When adding engine coolant

Coolant is neither plain water nor straight antifreeze. The correct mixture of
water and antifreeze must be used to provide proper lubrication, corrosion
protection and cooling. Be sure to read the antifreeze or coolant label.

■

If you spill coolant

Be sure to wash it off with water to prevent damage to parts or paint.

CAUTION

■

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.

AWD models: Do not fail to
initialize the tire pressure
warning system after tire
rotation.

■

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. (

→P. 400)

The compact spare tire is not equipped with the tire pressure
warning valves and transmitters.

Installing tire pressure warning valves and transmitters

When replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.

When new tire pressure warning valves and transmitters are
installed, new tire pressure warning valve and transmitter ID codes
must be registered in the tire pressure warning computer and the tire
pressure warning system must be initialized. Have tire pressure
warning valve and transmitter ID codes registered by your Toyota
dealer

. (

→P. 352)

Initializing the tire pressure warning system

■

The tire pressure warning system must be initialized in the fol-
lowing circumstances:

● When rotating the tires on vehicles differing with front and rear tire

inflation pressure.

● When changing the tire size.

When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the pressure benchmark.

How to initialize the tire pressure warning system

Park the vehicle in a safe place and turn the engine switch
OFF.

While the vehicle is moving, initialization is not performed.

Adjust the tire inflation pressure to the specified cold tire infla-
tion pressure level. (

→P. 451)

Make sure to adjust the tire pressure to the specified cold tire
inflation pressure level. The tire pressure warning system will
operate based on this pressure level.

Turn the engine switch to the “ON” position.

Push and hold the tire pressure
warning reset switch until the tire
pressure warning light blinks
slowly 3 times.

Wait for a few minutes with the engine switch in the “ON” posi-
tion, and then turn the engine switch to the “LOCK” position.

Registering ID codes

The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to register the ID code of tire pressure
warning valve and transmitter. Have the ID code registered by your
Toyota dealer.

■

When to replace your vehicle’s tires
Tires should be replaced if:

●

You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric, or bulges indicating internal damage

●

A tire goes flat repeatedly or cannot be properly repaired due to the
size or location of a cut or other damage

If you are not sure, consult with your Toyota dealer.

■

Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pressure warning system will not work properly. After
driving for about 20 minutes, the tire pressure warning light comes on
after blinking for 1 minute to indicate a system malfunction.

■

Tire life
Any tire over 6 years old must be checked by a qualified technician even
if they have seldom or never been used or damage is not obvious.

■

If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.

■

If you push the tire pressure warning reset switch accidentally
If initialization is performed, adjust the tire inflation pressure to the speci-
fied level and initialize the tire pressure warning system again.

■

When the initialization of the tire pressure warning system has
failed
Initialization can be completed in a few minutes. However, in the follow-
ing cases, the settings have not been recorded and the system will not
operate properly. If repeated attempts to record tire inflation pressure
settings are unsuccessful, have the vehicle inspected by your Toyota
dealer.

●

When operating the tire pressure warning reset switch, the tire pres-
sure warning light does not blink 3 times.

●

After carrying out the initialization procedure, the tire pressure warn-
ing light blinks for 1 minute then stays on after driving for about 20
minutes.

■

Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation
pressure checks. Make sure to check tire inflation pressure as part of
your routine of daily vehicle checks.

■

Maximum load of tire
Check that the maximum load of the replacement tire is greater than 1/2
of the Gross Axle Weight Ratings (GAWR) of either the front axle or the
rear axle, whichever is greater.

■

Low profile tires (models not equipped with 16-inch tires)
Generally, low profile tires will wear more rapidly and tire grip perfor-
mance will be reduced on snowy and/or icy roads when compared to
standard tires. Be sure to use snow tires or tire chains

*

on snowy and/or

icy roads and drive carefully at a speed appropriate for road and weather
conditions.

*

: Tire chains cannot be mounted on 18-inch tires.

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. (

Tire types
1 Summer tires

Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Since summer tires do not have the same
traction performance as snow tires, 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.

3 Snow 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 originally 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 restrictions. Snow tires
should be installed on all wheels. (

→P. 162)

■

Initializing the tire pressure warning system
Initialize the tires with the tire inflation pressure adjusted to the specified
level.

CAUTION

■

When inspecting or replacing tires
Observe the following precautions to prevent accidents. Failure to do so
may cause damage to parts of the drive train, as well as dangerous han-
dling characteristics, which may lead to an accident resulting in death or
serious injury.

●

Do not mix tires of different makes, models or tread patterns. Also, do not
mix tires of remarkably different treadwear.

●

Do not use tire sizes other than those recommended by Toyota.

●

Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).

●

Do not mix summer, all season and winter tires.

■

When initializing the tire pressure warning system
Do not push the tire pressure warning reset switch without first adjusting
the tire inflation pressure to the specified level. Otherwise, the tire pres-
sure warning light may not come on even if the tire inflation pressure is
low, or it may come on when the tire inflation pressure 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 pressure
warning valves and transmitters may be damaged if not handled correctly.

●

When replacing tire valve caps, do not use tire valve caps other than those
specified. The cap may become stuck.

■

To avoid damage to the tire pressure warning valves and transmit-
ters
When a tire is repaired with liquid sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sealant is
used, contact your Toyota dealer or other qualified service shop as soon
as possible. Make sure to replace the tire pressure warning valve and
transmitter when replacing the tire. (

→P. 350)

■

Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot-
holes.
These conditions may cause losses in tire air 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.

■

Low profile tires and wheels
Wheels with profile tires like 17- and 18-inch tires may cause greater
damage than usual to the tire wheel when receiving impact from the road
surface. Therefore pay attention to the following:

●

Be sure to use proper tire inflation pressure. If tires are under-inflated,
they may be damaged more severely.

●

Avoid pot holes, uneven pavement, curbs and other road hazards.
Failure to do so can lead to severe tire and wheel damage.

■

If tire inflation pressures become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.
