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 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, 89)
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.

The hood will pop up slightly.
2Push the auxiliary catch lever to
the left and lift the hood.
WARNING
●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.357)
■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.

■Before recharging
When recharging, the battery produces hydrogen gas which is flammable and explosive. Therefore, observe the fol-
lowing precautions before recharging:
●If recharging with the battery installed
on the vehicle, be sure to disconnect the ground cable.
●Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the battery.
■After recharging/reconnecting the battery (vehicles with a smart entry
& start system)
●Unlocking the doors using the smart
entry & start system may not be possi- ble immediately after reconnecting the battery. If this happens, use the wire-
less remote control or the mechanical key to lock/unlock the doors.
●Start the engine with the engine switch in ACC. The engine may not start with the engine switch turned off.
However, the engine will operate nor- mally from the second attempt.
●The engine switch mode is recorded by the vehicle. If the battery is recon-nected, the vehicle will return the
engine switch mode to the status it
was in before the battery was discon- nected. Make sure to turn off the engine before disconnecting the bat-
tery. Take extra care when connecting the battery if the engine switch mode prior to discharge is unknown.
If the system will not start even after
multiple attempts, contact any autho-
rized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer.
