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.

 Stop the vehicle in a safe place
on a hard, flat surface.
 Set the parking brake.
 Shift the shift lever to P (auto-
matic transmission) or R (manual
transmission).
 Stop the engine.
 Turn on the emergency flashers.
( P.326)
 Check the degree of the tire
damage.
A tire should only be repaired with
the emergency tire puncture repair
If you have a flat tire
Your vehicle is not equipped
with a spare tire, but instead is
equipped with an emergency
tire puncture repair kit.
A puncture caused by a nail or
screw passing through the tire
tread can be repaired tempo-
rarily with the emergency tire
puncture repair kit.
WA R N I N G
■If you have a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the
wheel beyond repair. Driving with a
flat tire may cause a circumferential groove on the side wall. In such a
case, the tire may explode when
using the emergency tire puncture repair kit, resulting in death or serious
injury.
Before repairing the vehicle

3627-2. Steps to take in an emergency
1Stop the vehicle in a safe place
and turn off the air conditioning
system, and then stop the
engine.
2 If you see steam: Carefully lift
the hood after the steam sub-
sides.
If you do not see steam: Care-
fully lift the hood.
3 After the engine has cooled
down sufficiently, inspect the
WA R N I N G
●In the event that battery fluid comes
into contact with the skin or eyes,
immediately wash the affected area with water and seek medical atten-
tion. Place a wet sponge or cloth
over the affected area until medical attention can be received.
●Always wash your hands after han-
dling the battery support, terminals, and other battery-related parts.
●Do not allow children near the bat-tery.
■To prevent damage to the vehicle
Do not pull- or push-start the vehicle
as the three-way catalytic converter
may overheat and become a fire haz- ard.
NOTICE
■When handling jumper cables
Be careful that the jumper cables do
not become tangled in the cooling fans or any of the belts when connect-
ing or disconnecting them.
■When closing the doors
While pushing the door glass towards
the inside of the vehicle, slowly close the door.
Because the side window open/close
function linked to door operation will not operate, the window may interfere
with the vehicle body, possibly
scratching both the vehicle body and window, or even shattering the win-
dow.
If your vehicle overheats
The following may indicate that
your vehicle is overheating.
 The engine coolant tempera-
ture gauge ( P.88) is in the
red zone or a loss of engine
power is experienced. (For
example, the vehicle speed
does not increase.)
 “High Coolant Temperature
Check Owner's Manual” is
shown on the multi-information
display.
 Steam comes out from under
the hood.

●If steam is seen coming from under
the hood, do not open the hood
until the steam has subsided. The engine compartment may be very
hot.
●Keep hands and clothing (espe-
cially a tie, a scarf or a muffler)
away from the fans and belts. Fail-
ure to do so may cause the hands or clothing to be caught, resulting in
serious injury.
●Do not loosen the coolant reservoir
caps while the engine and radiator
are hot. High temperature steam or coolant
could spray out.
NOTICE
■When adding engine coolant
Add coolant slowly after the engine
has cooled down sufficiently. Adding
cool coolant to a hot engine too
quickly can cause damage to the engine.
■To prevent damage to the cooling system
Observe the following precautions:
●Avoid contaminating the coolant
with foreign matter (such as sand or
dust etc.).
●Do not use any coolant additive.
If the vehicle becomes
stuck
Carry out the following proce-
dures if the tires spin or the
vehicle becomes stuck in mud,
dirt or snow:
