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.

■Checking the oil type and pre-
paring the item needed
Make sure to check the oil type and
prepare the items needed before
adding oil.

1Remove the oil filler cap by turn-
ing it counterclockwise.
2 Add engine oil slowly, checking
the dipstick.
3 Install the oil filler cap by turning
it clockwise.
■Engine oil consumption
A certain amount of engine oil will be
consumed while driving. In the following situations, oil consumption may
increase, and engine oil may need to be
refilled in between oil maintenance inter- vals.
●When the engine is new, for example directly after purchasing the vehicle or
after replacing the engine
●If low quality oil or oil of an inappropri-
ate viscosity is used
●When driving at high engine speeds
or with a heavy load, when towing, or
when driving while accelerating or decelerating frequently
●When leaving the engine idling for a long time, or when driving frequently
through heavy traffic
■After changing the engine oil
The engine oil maintenance data should
be reset. Perform the following proce- dures:
1 Press or of the meter con-
trol switch to select .
2 Press or to select “Vehicle
Settings” and then press and hold
.
3 Press or to select “Oil Main-
tenance” and then press .
4 Press or to select “Yes” and
then press .
A message will be displayed on the
multi-information display when the reset
procedure has been completed.
WA R N I N G
■Used engine oil
●Used engine oil contains poten-
tially harmful contaminants which
may cause skin disorders such as inflammation and skin cancer, so
care should be taken to avoid pro-
longed 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 fil-
ters in household trash, in sewers
or onto the ground. Call any authorized Toyota retailer
or Toyota authorized repairer, or
any reliable repairer, service station or auto parts store for information
concerning recycling or disposal.
●Do not leave used engine oil within
the reach of children.
NOTICE
■To prevent serious engine dam- age
Check the oil level on a regular basis.

■Engine coolant reservoir
The coolant level is satisfactory if it
is between the “FULL” and “LOW”
lines on the reservoir when the
engine is cold.
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the “LOW”
line, add coolant up to the “FULL” line.
( P.560)
■Intercooler coolant reservoir
The coolant level is satisfactory if it
is between the “F” and “L” lines on
the reservoir when the engine is
cold.
Reservoir cap
“F” line
“L” line
If the level is on or below the “L” line,
add coolant up to the “F” line. ( P.560)
■Coolant selection
Only use “Toyota Super Long Life Cool-
ant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with
long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-
ized water. (Minimum temperature:
-35°C [-31°F])
For more details about coolant, contact
any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
■If the coolant level drops within a
short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir caps, drain
cock and water pump.
If you cannot find a leak, have any authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer, test the cap and check for leaks in the cooling system.
NOTICE
■When replacing the engine oil
●Be careful not to spill engine oil on
the vehicle components.
●Avoid overfilling, or the engine
could be damaged.
●Check the oil level on the dipstick
every time you refill the vehicle.
●Be sure the engine oil filler cap is
properly tightened.
Checking the coolant

4767-3. Do-it-yourself maintenance
Check the radiator, condenser and
intercooler and clear away any for-
eign objects. If either of the above
parts is extremely dirty or you are
not sure of their condition, have
your vehicle inspected by any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
Check the battery as follows.
■Battery exterior
Make sure that the battery termi-
nals are not corroded and that there
are no loose connections, cracks,
or loose clamps.
Terminals
Hold-down clamp
■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 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

■When the engine is hot
Do not remove the engine coolant
reservoir cap and the intercooler cool- ant reservoir cap.
The cooling system may be under
pressure and may spray hot coolant if the cap is removed, causing serious
injuries, such as burns.
NOTICE
■When adding coolant
Coolant is neither plain water nor
straight antifreeze. The correct mix-
ture of water and antifreeze must be used to provide proper lubrication,
corrosion protection and cooling. Be
sure to read the antifreeze or coolant label.
■If you spill coolant
Be sure to wash it off with water to
prevent it from damaging parts or
paint.
