Listed below are the general maintenance items that should be per-

service shop for advice.

328 4-2. Maintenance
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 the 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 set 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.

Maintenance and care
■Engine oil consumption
●The amount of engine oil consumed depends on the oil viscosity, the
quality of the oil and the way the vehicle is driven.
●More oil is consumed under driving conditions such as high speeds and
frequent acceleration and deceleration.
●A new engine consumes more oil.
●When judging the amount of oil consumption, keep in mind that the oil
may have become diluted, making it difficult to judge the true level accu-
rately.
●Oil consumption: Max. 1.1 qt./600 miles, 0.9 Imp. qt./600 miles (1.0 L per
1000 km)
●If you consume more than 1.1 qt. (1.0 L, 0.9 Imp. qt.) every 600 miles
(1000 km), contact your Toyota dealer.
■
CAUTION
Used engine oil
●Used engine oil contains potentially harmful contaminants which may
cause skin disorders such as inflammation or skin cancer, so care should
be taken to avoid prolonged and repeated contact. To remove used engine
oil from your skin, wash thoroughly with soap and water.
●Dispose of used oil and filters only in a safe and acceptable manner. Do
not dispose of used oil and filters in household trash, in sewers or onto the
ground. Call your Toyota dealer, service station or auto parts store for
information concerning recycling or disposal.
●Do not leave used engine oil within the reach of children.

346 4-3. Do-it-yourself maintenance
Disconnect the claws and
remove the service cover.
Remove the reservoir cap.
Add brake fluid slowly while checking the fluid level.STEP2
STEP3
■Brake fluid can absorb moisture from the air
Excess moisture in the fluid can cause a dangerous loss of braking effi-
ciency. Use only newly opened brake fluid.
CAUTION
■When filling the reservoir
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets in your eyes, flush your eyes with clean water immediately.
If you still experience discomfort, see a doctor.

Maintenance and care
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. 352)
■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.

Maintenance and care
■When replacing wheels
The wheels of your Toyota, except for the compact spare tire, are
equipped with tire pressure warning valves and transmitters that allow
the tire pressure warning system to provide advanced warning in the
event of a loss in tire inflation pressure. Whenever wheels are replaced,
the tire pressure warning valves and transmitters must be installed.
(P. 352)
CAUTION
■When replacing wheels
●Do not use wheels that are a different size from those recommended in
the Owner’s Manual, as this may result in 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 accident, causing serious
injury or death.
NOTICE
■Replacing tire pressure warning valves and transmitters
●Because tire repair or replacement may affect the tire pressure warn-
ing valves and transmitters, make sure to have tires serviced by your
Toyota dealer or other qualified service shop. In addition, make sure to
purchase your tire pressure warning valves and transmitters at your
Toyota dealer.
●Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly
with non-genuine wheels.

5-1. Essential information
If your vehicle needs to be towed
Before towing
The following may indicate a problem with your transmission. Contact
your Toyota dealer before towing.
●The engine is running, but the vehicle will not move.
●The vehicle makes an abnormal sound.
If towing is necessary, we recommend having your vehicle towed by
your Toyota dealer or a commercial towing service, using a lift-type
truck or a flat bed truck.
Use a safety chain system for all towing, and abide by all state/pro-
vincial and local laws.
2WD models: If towing your vehicle with a wheel-lift type truck from
the front, the vehicle's rear wheels and axles must be in good condi-
tions. (P. 393, 396)
If they are damaged, use a towing dolly or flat bed truck.
AWD models: If towing your vehicle with a wheel-lift type truck, use a
towing dolly. (P. 393, 396)
