Maintenance requirements
■Repair and replacement
It is recommended that genuine Toyota parts be used for repair to ensure
performance of each system. If non-Toyota parts are used in replacement or
if a repair shop other than a Toyota dealer performs repairs, confirm the war-
ranty coverage.
To ensure safe and economical driv ing, day-to-day care and regular
maintenance is essential. It is the owner’s responsibility to perform
regular checks. Toyota recommen ds the following maintenance.
■General maintenance
Should be performed on a daily basis. This can be done by your-
self or by a Toyota dealer.
■ Scheduled maintenance
Should be performed at specified intervals according to the
maintenance schedule.
For details about maintenance items and schedules, refer to the
“Scheduled Maintenance Guide” or “Owner’s Manual Supplement”.
■Do-it-yourself maintenance
You can perform some maintenance procedures yourself.
Please be aware that do-it-yourself maintenance may affect war-
ranty coverage.
The use of Toyota Repair Manuals is recommended.

●Toyota technicians are well-trained specialists and are kept up to date
with the latest service information. They are well informed about the
operations of all systems on your vehicle.
● Keep a copy of the repair order. It proves that the maintenance that has
been performed is under warranty coverage. If any problem should arise
while your vehicle is under warranty, your Toyota dealer will promptly
take care of it.
CAUTION
■Warning in handling of battery
●Engine exhaust, some of its constituents, and a wide variety of automobile
components contain or emit chemicals known to the State of California to
cause cancer and birth defects and other reproductive harm. Work in a
well ventilated area.
● Oils, fuels and fluids contained in vehicles as well as waste produced by
component wear contain or emit chemicals known to the State of
California to cause cancer and birth defects or other reproductive harm.
Avoid exposure and wash any affected area immediately.
● Battery posts, terminals and related accessories contain lead and lead
compounds which are known to cause brain damage. Wash your hands

Emission inspection and maintenance (I/M) programs
Some states have vehicle emission inspection programs which
include OBD (On Board Diagnostics) checks. The OBD system moni-
tors the operation of th e emission control system.
■If the malfunction indicator lamp comes on
The OBD system determines that a problem exists somewhere
in the emission control system. Your vehicle may not pass the I/
M test and may need to be repaired. Contact your Toyota dealer
to service the vehicle.
■ Your vehicle may not pass the I/M test:
●When the battery is disconnected or discharged
Readiness codes that are se t during ordinary driving are
erased.
Also, depending on your driving habits, the readiness codes
may not be completely set.
● When the fuel tank cap is loose
The malfunction indicator lamp comes on as a temporary mal-
function and your vehicle may not pass the I/M test.
■ When the malfunction indicator lamp goes off after several
driving trips
The error code in the OBD system will not be cleared unless the
vehicle is driven 40 or more times.
■ If your vehicle does not pass the I/M test
Contact your Toyota dealer to prepare the vehicle for re-testing.

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 (U.S.A. only)
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. 422)
The compact spare tire is not equipped with the tire pressure
warning valve and transmitters.

Maintenance and care
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 pre ssure 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. 370)
Initializing the tire pressure warning system
The tire pressure warning system must be initialized when changing
the tire size.
When the tire pressure warning syst em 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 START
STOP” switch or the engine switch OFF.
While the vehicle is moving, in itialization is not performed.
Adjust the tire inflation pressure to the specified cold tire infla-
tion pressure level. ( P. 474)
Make sure to adjust the tire pressure to the specified cold tire
inflation pressure level. The ti re pressure warning system will
operate based on this pressure level.
Turn the “ENGINE START STOP” switch to IGNITION ON
mode (vehicles with smart key sy stem) or the engine switch to
the “ON” position (vehicles without smart key system).

■Low profile tires (vehicles with 17-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 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 restrictions. Snow tires
should be installed on all wheels. ( P. 181)
■Initializing the tire pr essure warning system
Initialize the tires with the tire inflati on pressure adjusted to the specified
level.
■If you push the tire pressure warning reset switch accidentally
If initialization is performed, adjust the tire in flation pressure to the speci-
fied level and initialize the tire pressure warning system again.
