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.85, 88)
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 fan 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.
●Do not leave anything that may burn easily, such as paper and
rags, in the engine compartment.

Maintenance and care
1 Pull the hood lock release lever.
The hood will pop up slightly.
2Pull the auxiliary catch lever to
the left and lift the hood.
WA R N I N G
●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 fan or radiator grille
Be sure the engine switch is OFF.
With the engine switch in ON, the electric cooling fan may automatically
start to run if the air conditioning is on
and/or the coolant temperature is high. (P.426)
■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.

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.
Positioning a floor jack
When using a floor jack, follow
the instructions in the manual
provided with the jack and per-
form the operation safely.
When raising your vehicle with
a floor jack, position the jack
correctly. Improper placement
may damage your vehicle or
cause injury.
