Maintenance and care
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 misses (misfire), 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, pedal almost touches the floor, vehicle pulls to one
side when braking
●Engine coolant temperature continu- ally higher than normal ( P.94, 99)
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.

Maintenance and care
WARNING
●Keep hands, clothing and tools away from the moving fan.
●Be careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other flu-ids may also be hot.
●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 12- volt battery. Fuel and 12-volt battery fumes are flammable.
●Be extremely cautious when work-ing on the 12-volt battery. It con-
tains poisonous 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 power switch is OFF.
With the power 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.329)
■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.
