■Outside temperature display
●In the following situations, the correct
outside temperature may not be dis- played, or the display may take longer
than normal to change:
• When stopped, or driving at low speeds (less than 20 km/h [12 mph])
• When the outside temperature has
changed suddenly (at the entrance/exit of a garage, tunnel, etc.)
●When “--” is displayed, the system may be malfunctioning.
Take your vehicle to any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.

■The information display at low
temperatures
Allow the interior of the vehicle to warm up before using the liquid crys-
tal information display. At extremely
low temperatures, the information dis- play monitor may respond slowly, and
display changes may be delayed.
For example, there is a lag between
the driver’s shifting and the new gear number appearing on the display.
This lag could cause the driver to
downshift again, causing rapid and excessive engine braking and possi-
bly an accident resulting in death or
injury.
NOTICE
■To prevent damage to the engine
and its components
●Do not let the indicator needle of
the tachometer enter the red zone,
which indicates the maximum
engine speed.
●Pay extra attention to the engine
speed when the engine is cold, as the red zone will be lower than nor-
mal.
●If the engine coolant temperature
gauge indicator is flashing, the
engine may be overheating. Imme- diately stop the vehicle in a safe
place, and check the engine after it
has cooled completely. ( P.362)

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. 8 8 )
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.

2926-3. Do-it-yourself maintenance
WA R N I N G
■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.
●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, con- sult 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.298)
■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.

2986-3. Do-it-yourself maintenance
“TOYOTA Genuine 50/50 Pre-mixed
Super Long Life Coolant BLUE” is a mix- ture of 50% coolant and 50% deionized
water. (Minimum temperature: -35°C
[-31°F])
For more details about engine coolant,
contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
■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 your Toyota dealer test the cap and check for
leaks in the cooling system.
Check the radiator and condenser
and clear away any foreign 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.
Hold-down clamp
Terminals
■Checking battery fluid
Check that the level is between the
“UPPER LEVEL” and “LOWER
LEVEL” lines.
WA R N I N G
■When the engine is hot
Do not remove the engine coolant reservoir cap. ( P.364)
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.
Checking the radiator and
condenser
WA R N I N G
■When the engine is hot
Do not touch the radiator or con-
denser as they may be hot and cause serious injuries, such as burns.
