■Where to go for maintenance ser-
vice?
In order to maintain your vehicle in the best possible condition, Toyota recom-
mends that maintenance service opera-
tions as well as other inspections and repairs be carried out by authorized
Toyota retailers or Toyota authorized
repairers, or any reliable repairers. For repairs and services covered by your
warranty, please visit an authorized
Toyota retailer or repairer, who will use genuine Toyota parts in repairing any
difficulties you may encounter. There
can also be advantages in utilizing authorized Toyota retailers or repairers
for non-warranty repairs and services,
as members of the Toyota network will be able to expertly assist you with any
difficulties you may encounter.
Your Toyota retailer or Toyota authorized
repairer, or any reliable repairer will per- form all of the scheduled maintenance
on your vehicle reliably and economi-
cally due to their experience with Toyota vehicles.
Scheduled maintenance should be
performed at specified intervals
according to the maintenance
schedule.
For full details of your maintenance
schedule, read the “Toyota Service
Booklet” or “Toyota Warranty Booklet”.
What about do-it-yourself mainte-
nance?
Many of the maintenance items are
easy to do yourself if you have a little
mechanical ability and a few basic
automotive tools.
Note, however, that some maintenance
tasks require special tools and skills.
These are best performed by qualified
technicians. Even if you're an experi-
enced do-it-yourself mechanic, we rec-
ommend that repairs and maintenance
be conducted by any authorized Toyota
retailer or Toyota authorized repairer, or
any reliable repairer. Any authorized
Toyota retailer or repairer will keep a
record of maintenance, which could be
useful should you ever require War-
ranty Service. Should you choose to
select a qualified and equipped profes-
sional other than an authorized Toyota
repairer to service or maintain your
vehicle, we recommend that you

request that a record of maintenance
be kept.
■Does your vehicle need repairs?
Be on the alert for changes in perfor- mance and sounds, and visual tip-offs
that indicate service is needed. Some
important clues are:
●Engine missing, stumbling or pinging
●Appreciable loss of power
●Strange engine noises
●A fluid leak under the vehicle (How-
ever, water dripping from the air con- ditioning system after use is normal.)
●Change in exhaust sound (This may indicate a dangerous carbon monox-
ide leak. Drive with the windows open
and have the exhaust system checked immediately.)
●Flat-looking tires, excessive tire squeal when cornering, uneven tire
wear
●Vehicle pulls to one side when driven
straight on a level road
●Strange noises related to suspension
movement
●Loss of brake effectiveness, spongy
feeling brake pedal or clutch pedal
(vehicles with a manual transmission),
pedal almost touches the floor, vehicle pulls to one side when braking
●Engine coolant temperature continu-ally higher than normal ( P.89, 93)
If you notice any of these clues, take
your vehicle to any authorized Toyota retailer or Toyota authorized repairer, or
any reliable repairer as soon as possi-
ble. Your vehicle may need adjustment or repair.

WA R N I N G
The engine compartment contains many mechanisms and fluids that
may move suddenly, become hot, or
become electrically energized. To avoid death or serious injury, observe
the following precautions.
■When working on the engine
compartment
●Keep hands, clothing and tools away from the moving fans and
engine drive belt.
●Be careful not to touch the engine,
radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.

Maintenance and care
WA R N I N G
●Do not leave anything that may
burn easily, such as paper and
rags, in the engine compartment.
●Do not smoke, cause sparks or
expose an open flame to fuel or the battery. Fuel and battery fumes are
flammable.
●Be extremely cautious when work- ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
●Take care because brake fluid can
harm your hands or eyes and dam-
age painted surfaces. If fluid gets on your hands or in your eyes, flush
the affected area with clean water
immediately. If you still experience discomfort,
consult a doctor.
■When working near the electric
cooling fans or radiator grille
Be sure the engine switch is OFF. With the engine switch in ON, the
electric cooling fans may automati-
cally start to run if the air conditioning is on and/or the coolant temperature
is high. (P.476)
■Safety glasses
Wear safety glasses to prevent flying
or falling material, fluid spray, etc. from getting in your eyes.
NOTICE
■If you remove the air cleaner fil-
ter
Driving with the air cleaner filter removed may cause excessive
engine wear due to dirt in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to
go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refill-
ing, it may indicate a serious problem.

Opening the hood
WA R N I N G
■Pre-driving check
Check that the hood is fully closed
and locked.
If the hood is not locked properly, it
may open while the vehicle is in motion and cause an accident, which
may result in death or serious injury.
■After installing the support rod
into the slot
Make sure the rod supports the hood securely preventing it from falling
down onto your head or body.
NOTICE
■When closing the hood
Be sure to return the support rod to its
clip before closing the hood. Closing
the hood with the support rod not clipped could cause the hood to bend.
